ABSTRACT

This thesis develops a method and a resulting computer

program for estimating the energy input required by the

heating-cooling-ventilating system of a building. The

computer program has the ability to model the ventilating

system and all the inefficiencies introduced when the heating

system is allowed to fight the cooling system to provide

temperature control within the conditioned space. The program

also can consider mechanical heat reclaim accurately, making

the consideration on a time of need versus a time of occurrence

basis.

The program is written to utilize input data in rather

simplified form. This allows the program to be used during

early design stages for a project when only general concepts

ii

are available to get comparisons of types of systems, or final

design characteristics may be used to prepare highly accurate

estimates. Weather data is used in such a form that average

data for a period of years can be used for input or any specific

year may be used individually.

ACKNOWLEDGEMENTS

The author wishes to thank Professor J. D. Morgan,

University of Missouri - Rolla, for his advice and

iii

assistance in preparing this thesis and Mr. George C. Wagner,

Union Electric Company, and Union Electric Company for

allowing the work done by the author to be used as the

subject matter for this thesis.

I. INTRODUCTION

During the past 10 to 15 years, many electric utilities

have seen their systems become the victim of large summer

l.

air conditioning loads which have reduced annual load factors

and resulted in summer generating peaks far greater than

winter peaks. Union Electric Company in St. Louis had a

summer peak of ~000 MW in 1969 with an annual load factor of

slightly more than 50% for the year. This combined with the

fact that transmission and distribution facilities in our area

have about ~0% greater load capacity in winter than in summer

have prompted Union Electric to look for s~lective loads that

will take advantage of this summer-winter unbalance to better

utilize system facilities and maximize return on investment.

Electric space heating is a load that has the potential to

bring back into balance summer and winter peaks and to greatly

improve annual load factor.

Electric utilities have spent large sums of money; and

expended many manhours promoting electric space heating.

Virtually all companies now have special rates for space heat

ing. Union Electric Company 1 s rates are such that electric

heating should be considered for every new building being

constructed, with electric heating being competitive with

other fuels in most instances. This means that to effectively

promote space heating, the utility engineer must be able to

quickly and accurately evaluate a project and its proposed

heating system. This is relatively easy for small buildings

such as homes, small stores, etc. because they are either a

heating load or a cooling load at any given time and the

system required to satisfy the needs of the building are

relatively simple.

Such is not the case for larger buildings. Internal

2.

lighting loads in larger buildings, combined with an archi

tectural philosophy that permits large internal building

areas that have no outside exposure and consequently no heat

loss, result in buildings that almost always present a simul

taneous heating and cooling load for different parts of the

building. Also, in most instances, the heating and cooling

systems are worked against one another to gain temperature

control in the space. These problems and the fact that the

heating and cooling loads vary with the solar heat gain on the

perimeter of the building further complicate the situation.

Finally, these, and relatively new techniques such as mech

anical heat reclaimation and air-handling light fixtures have

combined to result in an unsolved problem of providing acc

urate electric heating and cooling estimates that can be cal

culated without unreasonable amounts of effort on the part of

the engineer.

The purpose of this thesis is to set forth a method that

3.

will accurately, to within 10%, produce an estimate of electri

cal consumption for the heating and cooling system in any build

ing, giving consideration not only to building thermal

characteristics but also to the particular heating-cooling-

ventilating system chosen. Since the calculations are so

numerous, any manual attempt at using this method is not prac

tical, hence the end result of this thesis is a computer program

utilizing this method. The program is written for an IBM

System 1130 having an 8 K core memory and 256,000 words of on

line disk storage.

The method of estimating and its associated program are

not intended to be an exact simulation technique, but rather

an accurate approximation utilizing simplified data inputs

and a relatively small and inexpensive computing system. The

important points developed in this method are the accurate

modeling of the heating and cooling system including ventila

tion air; the ability to reco~1ize concurrent heating and

cooling requirements; the ability to determine the efficien

cies of different systems using heating vs. cooling to gain

temperature control; and the ability to evaluate mechanical

heat reclaim on a time of occurence vs. a time of need basis.

II. REVIEW OF LITERATURE

Work has been done in the past on this subject by

Westinghouse Electric Corp., Arkansas Power and Light Company,

and American Electric Power. Work is presently under way by

Edison Electric Institute, Automated Procedures for Engineer

ing Consultants, United Stated Post Office Department and

American Society of Heating, Refrigeration, and Air Condi

tioning Engineers. A brief description of past work by the

individual companies listed above is as follows:

A. WESTINGHOUSE ELECTRIC CORPORATION

A computer program was originally developed for an IBM

70 94- sys tern. This program received as input data the building

construction characteristics and physical dimension data. It

then calculated heat loss and heat gain, and simulated a year 1 s

operation by using hourly U. S. Weather Bureau data for any

given location. It took these results and applied different

system configurations of equipment to determine energy input

to the building. Primary disadvantages of this method were

that no consideration of ventilating system type was included,

the building was always treated as a cooling load or a heating

load and never as a simultaneous condition, and only one

operating condition for inside temperature and ventilation

was allowed. Another great disadvantage was that very few

4-.

utilities had a computer comparable to the 709~ on which to

execute the program. This meant that anyone using the program

had to go to a service bureau type of operation which usually

is not satisfactory with this type of work.

B. ARKANSAS POWER AND LIGHT COMPANY

The work done by these people basically consisted of

taking the Westinghouse program and modifying it for use on

an IBM System 1130. VirtuaLly no changes were made in program

logic and as a result, the program still did not consider the

building as a simultaneous load, and only one operating condi-

tion could be studied. This program had the further disadvan-

5.

tage of taking a minimum of 1.3 hours to execute in its simplest

form with an additional 1 hour being added for each zone above

the first zone. The greatest advantage of this program was that

it utilized a small and inexpensive computing system and could

be used within the user company.

C. AMERICAN ELECTRIC POWER

This company also started with the Westinghouse program,

made certain revisions, added more types of systems for con-

sideration and wrote the program for an IBM System 360/50. This

program is propria tary and administered by the Electric Heating

Association to member companies only and run by American Electric

Power on their computer. The program still has the previously

6.

mentioned inaccuracies of no simultaneous heating and cooling

consideration and no modeling of the ventilating system. This

program is further complicated by the fact that no listing of

the program is available and this immediately minimizes its

value as a sales aid.

D. WORK PRESENTLY UNDER WAY

The work presently under way includes those groups ment-

ioned previously in this section. In most instances, they are

at least two to four years away from any meaningful results.

Also, in the case of the American Society of Heating, Refriger

ation and Air Conditioning Engineers, their method will probably

be such that the accurate simulation technique they are develop

ing will require the detailed design of the system for input

data. This will greatly limit the usefullness of such a method

because it will not be easily usable as a design tool in the

early stages of system choice.

7.

III. DEFINITIONS AND DESCRIPTION OF WEATHER DATA

At this point, it would be well to define terms that will

be used throughout this thesis in developlng the mathematical

model for the system. Also, an understanding of the form that

the weather data takes on for this application is necessary.

A. DEFINITION OF TERMS

A brief definition of some of the terms used in the

following discussion will avoid confusion on the part of the

reader.

l. RETURN AIR TEMPERATURE

Temperature of air returning to ventilating system

from the conditioned space. It may be constant

at room temperature or variable if returned through

a ceiling plenum or cavity.

2. MIXED AIR TEMPERATURE

Temperature of the mixture of return air and fresh

outside air prior to being conditioned by heating

and cooling system.

3. CEILING RETURN AIR PLENUM

A system where return air is drawn through lighting

fixtures or grilles into the space above the ceiling

and returned to the supply air fan. Some of the

heat generated by light fixtures is prevented from

entering the conditioned space thereby reducing

the cooling requirement of the space. Under this

condition, the return air temperature can differ

from room temperature.

4. IN-SPACE REQUIREMENTS

Those heat loss and heat gain components that occur

within the conditioned space or area. They include

gains and losses from walls, floors, glass, people,

lights, other internal loads, roof (only if a ceil

ing return air plenum is not used) and ventilation

or infiltration (only if a central ventilating

system is not used).

5. BALANCE TEMPERATURE

The temperature at which the heat losses of a space

are just equal to the internal heat gains including

people but not including solar heat gain.

6. UNIT SYSTEM

A conditioning system where the heat exchanger is

located within the given room or space. This ex-

8.

changer may be supplied with energy from some remote

location but the exchange of heat actually takes

place within this room. Examples of this are base-

board heaters, unit ventilators, finned radiation,

etc.

7. CENTRAL SYSTEM

A system where the heat exchanger is located out

side the conditioned room and it serves more than

one room or space. Examples of this are central

ventilating systems.

8. MECHANICAL HEAT RECLAIM

A mechanical air conditioning machine that has

double condensing water circuits with one circuit

going back to the heating system hot water circuit.

This enables heat mechanically removed from one

area of the building to be put back into the build

ings heating system.

B. WEATHER DATA

9.

Weather data for virtually all cities is available on an

hourly basis for past years from the U. S. Weather Center in

Ashville, North Carolina. The data available includes dry

and wet bulb temperatures, barometric pressure, wind condi

tions, precipitation and cloud cover for each hour of the

year. Since this program is not an hour by hour simulation,

the data in this form is not of great value since sequential

processing of hourly temperature readings is too time con

suming. Methods presently used by Union Electric Company

for electric heating estimates accept weather data arranged

by total number of hourly observations per month within 5° F.

temperature ranges. For simple space heating estimates, this

is within reasonable accuracy without considering the hour of

of the day that the observation occurred. When the estimates

are to include air conditioning and mechanical heat reclaim,

10.

it becomes necessary to consider also the hour of the day in

which the observation occurred. This is necessary because part

of the cooling load is radiant load not present at night; and

when considering heat reclaim, the heat reclaimed must be avail-

able for use at the hour when it is needed.

Weather data for this program was set up monthly on the

basis shown in Figure 1 where hourly temperature observations

0 were segregated by 5 F. temperature ranges and by hour of

occurrence. Along with this, the average humidity ratio for

temperature ranges above 70°F. is included to enable an esti-

mate for maintaining fixed humidity conditions. This program

only calculates summer dehumidification and humidity ratios

0 are zeroed for temperature ranges below 70 F.

Weather data is not available in this form and must be

sorted and preferably averaged over a period of years. The

original data mentioned previously is available from the U. S.

Weather Bureau and a computer program for processing the data

into the form of Figure l is included in Appendix C. The

complete set of weather data used for the test case presented

in Chapter VII is included in Appendix B.

IV. DEVELOPMENT OF THE SYSTEM MODEL

The model for this program consists of two major model

components and a number of sub-models. Dependent upon the

heating system selected, the program may use all major models

and all sub-models or as few as just one major model and no

sub-models.

A. IN-SPACE MODEL

The in-space model concerns itself with only those cond

itions that occur within the conditioned space. Assume for the

moment a simple room as the conditioned space. That room may

have as minimum considerations structural heat loss, structural

and solar heat gain, heat gain from lights and other loads and

heat gain from people. The room may also have ventilation or

infiltration (ingress of outside air around windows and doors)

loads dependent upon the type of heating system used. If the

room has a unit type system, then the ventilation and infil

tration heat gains and losses become part of the in-space

module. If the room is supplied by a central ventilating

system, then these loads are a part of the ventilating system

model.

One major assumption that will be made is that solar and

structural heat gain will not be considered until the space has

attained its balance temperature. This assumption will tend to

13.

increase space heating requirements and minimize cooling req-

uirements. The actual effect of this will be discussed further

under the general heading of errors.

Figure 2 gives a graphical representation of the heating

or cooling requirements of the space. Those quantities above

the x-axis represent heating loads and those below represent

cooling loads. The expression for heat requirement Q is as

follows:

When T ( TB,

Q =Structural Heat Loss (T) - Internal

Sensible Heat Gain.

Q =Structural Heat Loss (T) - Internal Sensible

Heat Gain- Solar and Structural Heat Gain (T).

When T > TIS,

Q = - Internal Sensible Heat Gain - Solar and

S true tura l Heat Gain (T) - In te rna l La tent

Heat Gain (T).

Where:

Q = Heat Requirement maintaining sign integrity.

Positive values are heating requirements and

negative values are cooling requirements, in Btu/hr.

0 T =Outdoor ambient temperature in F.

TB= Balance Temperature in °F. where the internal

sensible heat gain balances heat loss.

TIS = Inside or in-space temperature in °F.

These general equations can be furthur formalized in the

initial case for T < TB'

Q = HL

Where:

(TIS - T)

l ) - HGLT - HGps - HGOTH Tis - TwD

(l)

HL =Design Heat Loss in Btu/Hr.

HGLT =Heat Gain to Space from lighting in Btu/Hr.

HGps = Sensible Heat Gain to Space from people in

Btu/Hr.

HGOTH = Heat Gain from any other Internal Source in

Dtu/Hr.

TwD =Outdoor Winter Design Temperature in oF.

By successively evaluating (l) for increasing values of T

and checking Q for positive sign, when Q becomes negative, the

value of TB has been determined. Progressing then to the

second case for TD < T ~ Tis,

(Tis-T) (T-TB) Q = HL (Trs-TwD) - HGsT (TsD-TB) - HGLT - HGps - HGoTH (2)

Where:

HGST = Design Structural and Solar Sensible Heat

Gain in Btu/Hr.

0 = Outdoor Summer Design Temperature in F.

16.

Q as determined by (2) will have a negative value repre-

senting a cooling load. The third case is for T > TIS,

Where:

HGPL =Heat Gain to Space from People, Latent in

Btu/Hr.

In the foregoing (l), (2) and (3), any portion of the

lighting load given up to a ceiling air plenum must not be

included if the space has a ceiling plenum. When the space

has a ceiling plenum, the appropriate value for HGLT becomes,

(LJ-)

Where:

KWLT = Lighting Load in KW.

PRA = Per cent of Lighting Load given up to Ceiling

Plenum. This value is available from fixture

manufacturer.

These equations provide the basic formulation for determining

the heat requirement (Q) of the space. Equations (2) and (3)

must now be adjusted for variations of structural and solar

heat gain (HGsr) related to hour of occurrence. Since no solar

gain is present during night hours and the amount present during

day hours varies with season, the correction factor must vary

to attempt to match the actual conditions.

17.

Data was taken from the American Society of Heating, Ref

rigeration and Air Conditioning Engineerrs Guide giving solar

radiation intensities in Btu/Sq. Ft. on vertical surfaces

during daylight hours for each month. These were averaged for

north, east, south and west exposures for the design day of

each month. Table 1 shows this table of solar radiation in

tensities. Also shown is a temperature correction factor which

includes heat gain due to outside temperature above room temp-

erature. This correction factor has been applied to only those

intensities having the parenthesis below indicating the amount

included in that particular intensity. This temperature corr

ection factor is based upon expected maximum daily temperature

and single pane glass for the structure.

For the purposes of simplicity in structuring the computer

program, one correction curve for the year with different cut

off points for each month would be most usable. The average

corrected solar intensity for each hour under consideration was

then calculated as shown in the average row of Table l. A diff

erence table was then constructed showing the difference bet

ween the hourly average and the actual corrected solar inten

sity. The differences for each month were then summed and

considered with respect to the total average corrected solar

intensity for that month to determine the monthly percent

difference. Table 2 shows this difference table and the result

ing monthly differences.

PLOT OF SOLAR GAIN CORRECTION FACTORS BY HOUR FOR TilE 12 NONTHS OF THE YEAR

FIGURE 3. (CONCLUDED)

N N .

2 3.

Since the average building usually has its heat gain

made up of l/3 solar gain, l/3 ventilation gain and l/3 int

ernal lighting and people gain, this means that the maximum

monthly error that would be introduced by using one curve

(the average corrected solar intensity values) for the entire

year would be about +2.5% in September. For the entire year,

less than +0.2% would be introduced. As a result, it is con

cluded that one curve using the average corrected hourly solar

intensities shown in Table l can be used. Figure 3

shows the family of monthly correction factor curves genera ted

from Table l. The only other difference is the inclusion of

solar gain at night during June, July and Au~~st to account

for the heat absorbing quality of buildings, commonly referred

to as nfly-wheel rr effect. The actual use of the solar gain

correction factor, later referred to a SGCOR, is shown in

Equation (18) on Page 34-.

B. VENTILATING SYSTEM MODEL

The requirements of the ventilating system are the most

difficult to express in rna thema tical terms. The type of vent-

ilating system, if one is present, can be one of many. All

ventilating systems have one thing in common however, that be

ing the requirement that a given amount of air entering the

system at a determinable temperature must be either heated or

cooled to a specified room temperature. For the present, we

need not concern ourselves with the room requirements because

2 4-.

we have calculated these in the in-space calculation. Looking

at only that portion of the air for a given space and consider-

ing that we know the mixed air temperature entering the system,

the heat requirement can be expressed as:

(5)

Where:

Q = Heating or Cooling Requirement, positive for

heating , negative for cooling~ in Btu/hr.

V = Supply Air for Room in C.F.M.

TIS = Inside Design Temperature in °F.

TMA =Mixed Air Temperature entering the Ventilating

0 System in F.

FKW = Central Fan Motor Capacity in K.W. if Fan is

enclosed within Ventilating Duct System.

By maintaining algebraic sign integrity here and in the in-space

requirement calculation, the algebraic sum of these two quan-

tities will give the room requirement. If Q for the ventilat-

ing system were negative, indicating some cooling of the vent-

ilation air would be required, and Q of the space were positive,

indicating a heating load, the summing of the two would have

a cancelling effect, indicating the ventilating system was

supplying excess heat which the room needed.

The only variable to be defined in (5) is the mixed air

temperature. This can be pre-defined or it can be a function

of return air temperature and outside temperature. By the saiTE

25.

token, return air temperature can be constant or a function

of ceiling plenum characteristics if a ceiling plenum return

air system is used. Each of these will be investigated

separately.

l. DEFINED MIXED AIR TEMPERATURE PROFILE

The simplest case to consider is that of a thermosta-

tically controlled mixed air temperature. The mixture

of outside air and return air is constantly adjusted

to maintain the desired mixed air temperature being

called for by the mixed air thermostat. Normally,

this condition will shift over to minimum outside

air settings when mechanical cooling is required and

this will require the mixed air temperature to be

calculated corresponding to various outside tempera-

tures. For this particular discussion however, we

are only concerned with pre-defined mixed air tempera-

tures which are already in usable form to be applied

with(5). The pre-defined case may have a constant

0 mixed air temperature specified such as 55 F. for all

0 outdoor temperatures below 55 F., or they may be

varied or re-set downward as outdoor temperatures in-

crease. An example of the latter would be a straight

line re-set maintaining 70°F. mixed air temperature

at 0°F. outdoors and 55°F. mixed air temperature at

0 55 F. outdoors.

26.

2. UNDEFINED MIXED AIR TEMPERATURES

If the ventilating system operates with a constant

intake of outside air, then the mixed air temperature

becomes a variable that is a function of outside air

temperature and return air temperature. Assuming for

the moment that return air temperature is a known

quantity, then the mixed air temperature can be ex

pressed as,

TMA =

0 F.

The next problem becomes one of determining return

(6)

air temperatures. If the return air is simply drawn

out of the space through air grilles in a conventional

manner, then return air temperature will be the same

as in-space temperature, neglecting any duct loss or

gain outside the space. In this event, (6) becomes,

Vosx(TALVJB) - CV-Vos)xTis

v (7)

When the return air is removed through a ceiling re-

27.

turn plenum system, then return air becomes a function

of outdoor temperature, of lighting load and that per-

centage of the lighting load going to the return air,

of in-space temperature, of solar heat gain on exposed

plenum surfaces and air volume being considered.

Figure 4 illustrates these items. Taking these com-

ponents individually, for plenum heat loss we will

have,

(8)

Where:

UHLp = Design Unit Heat Loss of Plenum in

0 Btu/Hr/ F. Temp. Diff.

TpL = Plenum Temperature in oF.

Again, as with the in-space calculations, it will be

assumed that there is no solar or structural heat gain

to the plenum until the heat loss of the plenum is

totally offset by fixed internal heat gain to the

plenum. In this case, this becomes the quantity of

lighting fixture heat injected to the plenum space.

Solar and structural heat gain to the plenum will then

be considered on a straight line basis from this bal-

ance temperature (TBp) to summer outdoor design temp-

erature, with the heat gain ranging from 0 to design

load respectively. The expression for plenum solar

and structural gain then becomes,

Q (Gain to Plenum) = UHGpx (TAt-m-TBp)

Where:

29.

(9)

UHGp = Design Solar and Structural Unit Heat

Gain to Plenum in Btu/Hr./°F. Temp. Diff.

TBP = Balance Temperature of Plenum in °F.

The remaining Q components to be defined are:

Q(Gain from Ltg.) = KWLTx 34-13. X PRA (10)

Where:

KWLT = Lighting Load in KW.

PRA = Percentage of Light Fixture Heat that is

given to Return Air Plenum.

Q(Gain from Room Air) = 1. 08 XV X Trs (ll)

Q(Total Return Air) = 1. 08 X V X TRA (12)

The basic heat balance equations must be set up now

to solve for TpL· Taking the first case where fixed

gain in the plenum from lighting does not exceed

plenum heat loss, or the resultant TpL will be less

than Trs,

Q (Total Return Air) = Q (Gain from Lighting) +

Q(Gain from Room Air) -

Q(Loss from Plenum) (13)

Substituting (8), (10), (11) and (12) into (13) and

30.

solving for TpL gives,

(l.08xVxTis) + (34l3.xKWLTxPRA) + (UHLpxTAMB) T - (14)

PL- UH~ + (1. 0 8 x V)

For TAMB ( TBP and TpL ( TIS·

Case Two occurs when TAMB is greater than the balance

temperature thereby including solar and structural

heat gain but less than the in-space temperature TIS

therefore requiring heat loss to also be included.

Adding (9) along with the others to (13) and solving

for TpL gives,

(1. 08 X V X Tis) + (3413. X KWLT x PRA) TpL= +

(1.08 x V) + UHLp

(UHGp x (TAMB- TBp)) + UHLp x TAMB

(1. 08 x V) + UHLp

For TBP ( TAMB ( TIS and TPL ) TIS.

(15)

The third case occurs when TAMB is greater than TIS'

resulting in heat loss no longer being a consideration.

If (8) is eliminated from (13) with (9), (10) , (11)

and (12) being included, solving for TpL gives,

1.08 XV

UHGp x (TAMB-TBp)

31.

Egua tions (14) , (15) and (16) define TpL for all out

door temperature ranges. Assuming idealized conditions

with no duct losses or gains outside the conditioned

space,

(17)

These values of TRA are now defined for determining

mixed air temperatures TMA and ultimately the heat

requirement of the ventilating system.

V. DESCRIPTION OF THE COMPUTATIONAL METHOD

The weather data and the heating-cooling load have now

been defined and using these two inputs, the system usage must

be determined. Reviewing Figure l which shows the weather

data as stored on disk data file, assume this information is

used in the following array form:

IHR (l, l) • • IHR (l ,N) .. IHR (l, 25)

IHR (M, l) • IHR (M, N) IHR (M, 25)

IHR (24, l) • • IHR (24, N) Il!R (2lt, 25)

Where:

IHR(M,N) = The Number of Hourly Temperature

M = l-+24 Observations occurring in Temperature

N = l-+24 Range M during Hour N.

riHR (M, 25)l =

LM = l-+2~ Average Water Ratio in# Water per

# Dry Air for Temperature Range M.

The combined effects of in-space requirements and venti-

lating system requirements will be considered as a one dim-

ensional array,

SPREQ (l)

SPREQ (2) • • •

SPREQ (24)

33.

Where:

fSPREQ (M)l =

~ = l-+2d Individual Heating or Cooling Require-

ments for each Temperature Range M.

Sign Integrity must be Maintained.

SPREQ (M) = Qin-Space (M) + QVen t (M)

These must be modified to compensate for hourly variations

in solar heat gain also considered as a one dimensional array,

SGCOR (l) SGCOR (N) SGCOR (24)

Where:

JSGCOR (N)J=

~ = 1~24 Solar Gain Correction Factor.

The heating and cooling usage will then be calculated into

a two dimensional array,

HTCOL (l, l) HTCOL (l ,N) HTCOL (l, 24) •

• HTCOL (M, l) . . . HTCOL (M, N) . . . HTCOL (~1, 24)

• HTCOL (24, l) HTCOL (24,N) HTCOL (24, 24)

Where:

HTCOL(M,N) =Heating or Cooling Requirement for

M = 1~24 Temperature Range JVJ during Hour N.

N = l-+24 Sign Integrity as before.

The general equation for calculating the values for this

3 4-.

array are,

HTCOL (M, N) = ~HR (M, N) x S PREQ (MJ

+ {'B'ID. x v08 x [w18-rHR (M,2s~ For:

- ~IGs T x [1-SGCOR (~ (18)

l < M < 24-

1 < N < 24-

Where:

v0 s for M ~ 16

or

or

TAMB < 70°F.

TAMB ~ 70°F.

HGsT = Design Structural and Solar Heat Gain

v08 = Outside Air Volume

Wrs = Inside Design Humidity Ratio

The 1 HTCOL 1 array is then sorted for positive values for

heating and negative values for cooling. These values are added

to the zone arrays 1 ZOHTG 1,

1 ZOCLG 1,

1 ZOFHT 1 and 1 ZORCL 1, these

arrays being the same size as 1 HTCOL 1, by the following orders:

For HTCOL(M,N) Positive,

ZOHTG (M, N) = HTCOL (M, N)

and if the heating can be done by mechanically reclaimed

heat,

ZOFHT(M,N) = HTCOL(M,N).

For HTCOL(M,N) Negative,

ZOCLG (M, N) = HTCOL (M, N)

and if this excess heat can be mechanically reclaimed

for use elsewhere,

ZORCL (M, N) = HTCOL (M, N)

35.

At the conclusion of all calculations for a zone, these

files are added to the total building files 1 TOHTG 1,

1 TOCLG 1,

1 TOFHT 1 and 1 TORCL 1 which are identical to the zone files in

size and composition.

Upon completion of the total building, the building files

are then summarized by month. The first step in this operation

is to determine what heating can be done by mechanical reclaim

if such a system is considered. This is done to see if a heat-

ing requirement occurs at the same hour and the same outdoor

condition as a cooling load (heat surplus) in some other part

of the building. If the condition is found where TOFHT (M, N) ) 0

and TORCL(M,N) > 0 for the same values of M and N, then for

TOHTG (M, N) < TORCL (M, N) ,

TOHTG (M,N) = TOHTG (M, N) - TOFHT (M, N) (19)

and for TOFHT (M, N) ) TORCL (M, N) ,

TOHTG (M,N) = TOHTG (M,N) - TORCL (M, N) (20)

TOFHT (M,N) = TORCL (M,N) (21)

The monthly totals then become,

Heat Requirement = ~~ TOHTG (M,N) (2 2) 24 24

M=l N=l Heat Reclaimed = ~ ~ TOFHT (M,N) (23)

M=l N=l Cooling Requirement = L: ~ TOCLG (M,N) (24)

VI. COMPUTER PROGRAM DOCUMENTATION

The mathematical formulation described in the previous

chapters must now be set up in such a way so as to accurately

model the building heating and cooling system. The following

discussion of the program flow chart and the input data forms

is intended to give the reader a working knowledge of the

program:

A. DISK DATA FILES

The program has 9 data files set up on disk storage for

use during program execution.

l. WEATHER DATA FILE

3 6.

There is one permanently stored weather data file.

The file has 288 records, each record consisting of

25 data words. Information is stored in integer form

with l number per data word. There are 24 records

per month and the data contained for each month is as

shown in Appendix C.

2. ZONE DATA FILES

There are 4 zone data files, one for each of the four

categories of space heating (ZOHTG), air conditioning

(ZOCLG), space heating that can be done with reclaim-

ed heat (ZOFHT) and air conditioning load that is avail-

able for heat reclaim (ZORCL) . Each file consists of

300 records, each record being 50 data words long and

3 7.

containing 25 real numbers. Each month consists of

25 records for each file. The first 24 numbers in

the first record contain the maximum demand for each

hour of the day. The 25th number in the first record

contains the fan kwhrs for the month. The next 24

records correspond to the 24 five degree temperature

range increments from -5 °F. to 115 °F. with the first

24 numbers of each record containing the requirement

or load for that five degree increment over the 24

hours. The 25th number of each record contains a

weighted average of load for that five degree incre

ment but this number is not used in this specific

application.

3. BUILDING DATA FILES

There are '+ building files, one each for space heat

ing (TOHTG), air conditioning (TOCLG), space heating

that can be done with reclaimed heat (TOFI-IT) and air

conditioning load that is available for heat reclaim

(TORCL) . These files are identical to the !,one Data

Files and have the same purpose except they store

building totals rather than zone totals.

13. PROGRAM FLOWCHART

The logical major steps of the computer program as shown

D. ERROR DISCUSSION

At this point, consideration of errors known to be in

herent with this computer program and a discussion of their

effect on estimates calculated by the program are in order.

A good understanding of this will be of help in making in

telligent use of this program.

l. INCLUSION OF SOLAR AND STRUCTURAL HEAT GAINS

In the discussion of in-space and ceiling plenum

solar and structural heat gains previously, these

quantities were not allowed to enter the calcula

tion until after the outdoor temperature had

exceeded the balance temperature (TB) of the space.

This means that until the heat loss of the space

was offset by internal lighting and people load,

there is no inclusion of solar and structural heat

gain. Obviously, since the space has solar heat

gain anytime the sun shines, this condition is not

correct.

The reason this was done was to make the resulting

55.

56.

estimate a conservative one. The end result of

this condition is that the heating estimate will be

greater than actually required and the cooling

estimate will be slightly low, dependent on type of

system considered and building characteristics. Since

the addition of heat to the building requires about

four times as much energy input as removal of the

same quantity of heat by the air conditioning system,

it can be seen the net effect of this condition is

to make the over-all estimate a conservative one.

Since the field of large all-electric heating and

cooling systems is still relatively new, it is in

the best interest of the electric utilities to retain

this conservativeness. As more experience is gained

with large systems, it may become desirable to modify

this approach; but for now, it should remain as is.

2. AVERAGING SOLAR AND STRUCTURAL HEAT GAINS

The computer program is designed to take one value for

solar and structural heat gain per area being con-

side red. Since the solar gain inclusion is based on

an average of solar radiation from four directions

and on outdoor temperature, the value for solar and

structural heat gain to be used should be carefully

chosen. If a zone or room has predominantly one or

57.

two exposed sides with the major glass areas, then

using maximum heat gain as the input for that zone

will result in a high estimate for air conditioning

usage. For this reason, maximum accuracy can be

obtained by using the average solar and structural

heat gain for the hours being considered.

The output from the Heating-Cooling Load Calculation

Program by Automated Procedures for Engineering Con

sultants is such that it gives the heat gains of a

structure on an hourly basis for 12 hours on the

design day for any month. If the building or zone

under consideration is fairly well symmetrically

balanced with respect to the different directions,

then the design solar heat gain can be used.

58.

VII. TEST PROBLEM AND COMPARISON WITH ACTUAL DATA

The only large building in St. Louis that has been in

operation long enough for sufficient operating data to be

collected for meaningful comparison is the McGraw Hill Office

Building. The building is approximately 110,000 square feet

and is conditioned with a double-duct high velocity air system

using electric hot water heaters and electric drive centrifugal

air conditioners. A total of 600 K.W. of electric hot water

heaters is used along with two 200 ton Carrier centrifugal

chillers. One of the chillers had a dual circuited condenser

which can reject heat either to the cooling towers or to the

hot-deck of the heating system, the purpose of this being to

mechanically reclaim heat from the interior of the building.

The air distribution system uses a ceiling plenum return

and air handling light fixtures which will remove about 65%

of the lighting heat from the conditioned space. The floor

plan is arranged such that individual offices are located

around the perimeter of the building with the inner area for

large offices. The following is a general breakdown of tech

nical design data for the building:

AH#3 4-,000 3,200 2. 7

The building is heated and air conditioned continuously

24- hours per day and there is no change in interior conditions

maintained during the unoccupied hours. A total of 66 K.W. of

lighting is left on during the unoccupied hours for security

lighting and all the remaining lights are turned on when the

0 outdoor temperature falls below 25 F. The exterior zone of

the building is taken to be that area from the outside walls

60.

to a point 15 feet towards the interior. The remainder of the

building is the interior zone and tabulations for these zones

are as follows:

Pages 63 thru 70 show the input data forms completed

for this test run and pages 71 thru 75 are the computer

print out of the estimated usage for the heating and cooling

system using weather data for the year 1964-.

Since the computer data is for the year 1964- and the

experience available is for the years 1967 and 1968, the

computer estimate must be adjusted to compensate for variations

in weather conditions. Also, some usages such as pumps and

exhaust fan operation are not included in the computer study

and must be added. The following shows the difference between

years on the weather conditions:

6l.

Year Heating Cooling

1964 (Data) 4726 Degree Days 1688 Degree Days

1967 4819 Degree Days 1448 Degree Days

1968 5119 Degree Days 1607 Degree Days

The adjustments for heating and cooling usage can then be

made on the computer estimate:

1967 Heating including Heat Reclaim KWHR:

4819 690,726 KWHR x 4726 = 705,000 KWHR

1967 Cooling:

1448 679,297 KWHR x 1688 = 582,000 KWHR

1968 Heating including Heat Reclaim KWHR:

5119 690,726 KWHR x 4726 = 750,000 KWHR

1968 Cooling:

1607 679,297 KWHR x 1688 = 647,000 KWHR

The other adjustment that must be made accounts for the

hot water circulating pumps that operate 9 months per year and

the building exhaust fans that operate continuously.

Hot Water Pumps- 26.2 K.W.

KWHR/Yr. = 26.2 x 720 Hours/Month x 9 Months

KWHR/Yr. = 170,000

Exhaust Fans - lO K.W.

KWHR/Yr. = lO x 720 Hours/Month x 9 Months

KWHR/Yr. = 86,400

62.

The adjusted computer estimate for KWHR usage then be-

comes:

1967 1968

Space Heating Usage 705,000 750,000

Air Conditioning Usage 582,000 64-7,000

Fan usage 1,34-8,700 1,34-8,700

0 ther Usages 256,4-00 256,4-00

Adjusted Computer Estimate 2,892,100 3,002,100

Comparing this with the actual heating and cooling system

usage for the years 1967 and 1968;

Actual Adjusted % Diff. Sub-Metered Computer from

Usage Estimate Actual

Year 1967 2,725,280 2,892,100 +6.2

Year 1968 3,317,280 3,002,100 -9.5

Two Year Total 6, 0 4-2, 5 60 5,894-,200 -2.4-

As can be seen, the individual yearly results are within

10% of actual usage. The two year average is within S% of the

actual usage. The probable cause of the improvement for the

two year comparison is that the exact effect of solar radiation

will vary from year to year independent of heating or cooling

degree days, but the greater the span of consideration, the

more likely that the norm or average will be approached.

VIII. CONCLUSIONS

The comparison of actual experience for the McGraw Hill

Office Building with the computer estimate tends to indicate

that the program is sufficiently accurate to meet the accuracy

criterion of 10 per cent established at the outset. This how

ever is not sufficient to justify blind obedience to the pro

gram because one test comparison is certainly not conclusive.

The problem lies in finding large buildings with sufficient

data to allow adequate testing of the program. There will

continue to be more comparisons made as more data from build

ings of this type becomes available, and possibly some changes

in the program will become necessary. For the present, the

attitude is that the program will be used with the results

being analyzed and judged using factors which are felt to be

reasonable from experience.

The program is one that proves to be extremely flexible

and usable. The input information can be as simplified or as

complete as desired dependent upon the stage of design and the

degree of accuracy wanted. Unlike most other programs that

require very detailed inputs with regard to heating system

components, this program can be used with general building

characteristics and a minimum of system design input to select

a particular system best suited for a given building. The

program can also be used to evaluate various schemes for

76.

,

zoning the building and the resulting effect on operating

costs.

This program in its present state should not be construed

as a final document but rather a beginning. The general feel

ing expressed by two national groups recently, the American

Society of Heating, Refrigeration and Air Conditioning Engi

neers' Task Force on Energy Analysis and the Automated Pro

cedures for Engineering Consultants Group, was that the

most desirable method to approach energy analysis problems

is with the classical hour by hour approach. In this fashion

the solar and structural heat gain could be adjusted with

respect to hourly sun position and cloud cover. To take this

program and re-structure it to accept such data would be rela

tively easy but it would extend the run time on a System 1130

to the point of being unusable, due to the extremely slow

access times to disk storage and the limited core storage

of this system. Progressing to larger computers such as a

System 360/~0 or larger with high speed disk capability

would make this re-structured program run in reasonable time,

such as 30 minutes or less. This is within the present running

time on the System 1130. The primary point to be made is that

the mathematical model developed herein for the ventilating

system and the in-space or room condition are the backbone

of this program and these are valid and easily used regardless

of the form of the weather data input. These methods can be

77.

the stepping stones to more elaborate inclusion of weather data

and still maintain the simplicity and convenience of this

program.
