FACTORS OF REVERBERATION TIME
A1.1 ABSORPTION COEFFICIENT
Sound is the mechanical vibration of particles in a medium such as
air, generated by vibrations at a source. When a source is turned on in a room,
sound waves propagate away from the source, encountering the room’s
bounding surfaces and objects in the room. This frequency-dependent
interaction results in the absorption and reflection of the energy of the sound
waves. If the source is turned off, these interactions lead to the decay of the
sound energy in the room. The latter quantity is the sum of the contributions
of the various absorptive surfaces, absorbent objects, and of the air in the
room. In rooms, chairs, people and their clothing are absorbent objects that
contribute to the sound absorption of the room. Table A1.1 (Wikipedia 2010)
gives an idea of how the different common building materials and finishes
absorb sound at different frequencies.

APPENDIX 1
NINE PRINCIPLES TO GUIDE PUBLIC POLICY OF
I) THE REGION: METROPOLIS, CITY, AND TOWN
II) THE NEIGHBORHOOD, THE DISTRICT, AND
THE CORRIDOR
III) THE BLOCK, THE STREET, AND THE BUILDING.
I) The region: Metropolis, City, and Town
1. Metropolitan regions are finite places with geographic
boundaries derived from topography, watersheds, coastlines,
farmlands, regional parks, and river basins. The metropolis is
made of multiple centers that are cities, towns, and villages,
each with its own identifiable center and edges.
2. The metropolitan region is a fundamental economic unit of the
contemporary world. Governmental cooperation, public
policy, physical planning, and economic strategies must
reflect this new reality.
3. The metropolis has a necessary and fragile relationship with
its agrarian hinterland and natural landscapes. The relationship
is environmental, economic, and cultural. Farmland and nature
are as important to the metropolis as the garden is to the
house.
4. Development patterns should not blur or eradicate the edges of
the metropolis. Infill development within existing urban areas
conserves environmental resources, economic investment, and
263
social fabric, while reclaiming marginal and abandoned areas.
Metropolitan regions should develop strategies to encourage
such infill development over peripheral expansion.
5. Wherever appropriate, new development contiguous to urban
boundaries should be organized as neighborhoods and
districts, and be integrated with the existing urban pattern.
Noncontiguous development should be organized as towns
and villages with their own urban edges, and planned for a job
/ housing balance, not as bedroom suburbs.
6. The development and redevelopment of towns and cities
should respect historical patterns, precedents, and boundaries.
7. Cities and towns should bring into proximity a broad spectrum
of public and private uses to support a regional economy that
benefits people of all incomes. Affordable housing should be
distributed throughout the region to match job opportunities
and to avoid concentrations of poverty.
8. The physical organization of the region should be supported
by a framework of transportation alternatives. Transit,
pedestrian, and bicycle systems should maximize access and
mobility throughout the region while reducing dependence
upon the automobile.
9. Revenues and resources can be shared more cooperatively
among the municipalities and centers within regions to avoid
destructive competition for tax base and to promote rational
coordination of transportation, recreation, public services,
housing, and community institutions.
264
II) The Neighborhood, the District, and the Corridor
1. The neighborhood, the district, and the corridor are the
essential elements of development and redevelopment in the
metropolis. They form identifiable areas that encourage citizens
to take the responsibility for their maintenance and evolution.
2. Neighborhoods should be compact, pedestrian-friendly, and
mixed-use. Districts generally emphasize a special single use,
and should follow the principles of neighborhood design
whenever possible. Corridors are regional connectors of
neighborhoods and districts; they range from boulevards and
rail lines to rivers and parkways.
3. Many activities of daily living should occur within walking
distance, allowing independence to those who do not drive,
especially the elderly and the young. Interconnected networks
of streets should be designed to encourage walking, reduce the
number and length of automobile trips, and conserve energy.
4. Within neighborhoods, a broad range of housing types and
price levels can bring people of diverse ages, races, and
incomes into daily interaction, strengthening the personal and
civic bonds essential to an authentic community.
5. Transit corridors, when properly planned and coordinated, can
help organize the metropolitan structure and revitalize urban
centers. In contrast, highway corridors should not displace
investment from existing centers.
6. Appropriate building densities and land uses should be within
walking distance of transit stops, permitting public transit to
become a viable alternative to the automobile.
265
7. Concentrations of civic, institutional, and commercial activity
should be embedded in neighborhoods and districts, not isolated
in remote, single-use complexes. Schools should be sized and
located to enable children to walk or bicycle to them.
8. The economic health and harmonious evolution of
neighborhoods, districts, and corridors can be improved through
graphic urban design codes, that serve as predictable guides for
change.
9. A range of parks, from tot-lots and village greens to ball fields
and community gardens, should be distributed within
neighborhoods. Conservation areas and open lands should be
used to define and connect different neighborhoods and districts.
III) The Block, the Street, and the Building
1. A primary task of all urban architecture and landscape design
is the physical definition of streets and public spaces as places
of shared use.
2. Individual architectural projects should be seamlessly linked
to their surroundings. This issue transcends style.
3. The revitalization of urban places depends on safety and
security. The design of streets and buildings should reinforce
safe environments, but not at the expense of accessibility and
openness.
4. In the contemporary metropolis, development must adequately
accommodate automobiles. It should do so in ways that
respect the pedestrian and the form of public space.
266
5. Streets and squares should be safe, comfortable, and
interesting to the pedestrian. Properly configured, they
encourage walking, and enable neighbours to know each other
and protect their communities.
6. Architecture and landscape design should grow from local
climate, topography, history, and building practice.
7. Civic buildings and public gathering places require important
sites to reinforce community identity and the culture of
democracy. They deserve distinctive form, because their role
is different from that of other buildings and places that
constitute the fabric of the city.
8. All buildings should provide their inhabitants with a clear
sense of location, weather and time. Natural methods of
heating and cooling can be more resource-efficient than
mechanical systems.
9. The preservation and renewal of historic buildings, districts,
and landscapes affirm the continuity and evolution of urban
society.

APPENDIX 4
THE DIFFERENT IMAGEABILITY PARAMETER ADDRESSED IN EACH CITY WITH THE
METHOD OF FORMULATION OF STANDARDS AND THE GUIDELINE PRINCIPLES
A. City/ Area: Downtown Halifax, Halifax Regional Municipality Guide line Principles are:1. Street Wall Height (M)To ensure a comfortable human-scaled street enclosure, street walls should be no less than 35’ and generally no greater than a heightproportional (1:1) to the width of the street as measured from one building face to the opposite building face. Along heritage streetscapes,the maximum street wall height should be consistent with the prevailing heights of the heritage buildings. Along the Waterfront, frontingbuilding walls are not to exceed 40’ to maintain a low-rise interface. Street wall placements are categorized according to setback standards.All retail frontages should be encouraged to reinforce the ‘main street’ qualities associated with the historic downtown, including:
Narrow shop fronts, high levels of transparency and frequent entries.Protecting pedestrians from the elements with awnings will be encouraged.Patios and other spill-out activity will be permitted and encouraged.A “street wall” is formed when buildings consistently line or front onto a street with consistent setbacks. The following qualitative
design aspects of the street wall should be considered:Design of the Street wallBuilding Orientation and PlacementRetail UsesResidential UsesSloping ConditionsMaterialsEntrancesRoof Line
272
2. Building Height ( M)
The most important part of the design of a building is the first three to four storeys, as that part of the building and the
established street wall affect the pedestrian experience.
3. Special Features
The articulation of a building is often what gives it a human scale and a sense of quality, through attention to detail.
Articulation implies a three-dimensional facade, where windows and other elements have depth, creating a dynamic play
of light and shadows. Typically the articulation will indicate the transition between floors and interior spaces, giving a
human scale to the facade. This articulation can also include changes in materials, or material treatments.
·To encourage continuity in the streetscape and to ensure vertical ‘breaks’ in the façade, buildings should be designed to
reinforce the following key elements through the use of setbacks, extrusions, textures, materials and/or detailing:
Base – Within the first four storeys, a base should be clearly defined and positively contribute to the quality of the
pedestrian environment through animation, transparency, articulation and material quality.
Middle – The body of the building above the base should contribute to the physical and visual quality of the overall
streetscape.
Top - The roof condition should be distinguished from the rest of the building and designed to contribute to the visual
quality of the skyline.
Buildings should contribute to a mix and variety of high quality architecture, while remaining respectful of downtown’s
context and tradition. To provide architectural variety and visual interest, other opportunities to articulate the massing should
be encouraged, including vertical and horizontal recesses or projections, datum lines, and changes in material, texture or
colour. Street facing facades should have the highest design quality; however, all publicly viewed facades at the side and rear
should have a consistent design expression.
273
Typically, street wall heights are determined by using a1:1 ratio with the street width from the base of one building to another.
Heritage buildings in need of repair can often be saved from demolition by integrating them with new developments.
Infill development on Street will help form a continuous street wall, improving the pedestrian experience.
B. City/ Area: High Land Square Business District, Akron, Ohio Guide line Principles are:
1. Street Enclosure
Require the development of all new buildings and infill development up to the street edge/property line to establish a solid
edge to the street along the building line. For retail buildings, the setback rule is straightforward: don’t have one.
Traditional retail, to be successful, must pull directly up to the sidewalk, so that people can see the merchandise in the
window. Parking lots in front are of course forbidden: there is little that is more destructive to pedestrian life.
2. Cross Section of the Street
Buildings should be at least two storeys in height to establish a sense of street enclosure.
The relationship between the height of the buildings and the width of the street is important when maintaining a pedestrian
oriented environment. A two-storeyed building (approximately 27 feet high) will give a height to width ratio of 1:3. A
three- storeyed building) approximately 40 feet high) will give a height to width ratio of 1:2. If buildings are too high
in relation to the width of the street, a canyon like effect can be created; if too low, there is no sense of enclosure.
The height to width ratio should be not less than 1:2.5 if a sense of enclosure is to be achieved
274
3. Promote mixed-use
Development throughout the district and particularly discourage single storey, single use development in the district.
Encourage a variety and intensity of street activity. Promote a continuous retail edge at the property line. Re -establish
street level retail continuity by infilling vacant sites. Develop a continuous retail edge on all new buildings, that connects
to existing retail buildings. Promote a continuous retail use at the pedestrian level with office or residential uses on the
upper floors.
4. Special Features
Street activities should include on-street parking. This brings people into the area at all times of the day and night, and
provides another level of activity and accessibility. Encourage local cafes in the district. Build the front of the café so that
a set of tables can extend the café out onto the street. Promote a sense of urban activity within the retail district that is
“unique”.
Vehicular and Pedestrian Access
Reinforce both vehicular and pedestrian access to the retail district. Off street parking should be convenient for customers
and visitors, but its visual impact should be minimized. Provide clear pedestrian links from the parking area to the street
and retail establishments. Parking should be provided behind the building and accessible from either adjacent street.
Parking on the street edge between buildings and the street drastically reduces a favorable height –to- width proportion on
the street.
Buffer the surrounding residential neighborhood from retail business uses. All service areas and trash containers must be
screened from view through the use of evergreen plant materials, masonry screens or similar solid structures compatible
with the building design.
Street Facades
Major facades and entrances to buildings should face West Market Street. Access to service bays and parking should be
275
from the cross street. The architectural composition of building elevations should express a base, middle, and top
articulation on all street facades.
Storefronts
At least 60% of the total area of the first floor façade facing West Market Street and the public square at Highland Avenue
should be windows display. Walls exposed to side streets must have doors, windows or fixed glazing areas of at least 30%
of the total surface area of the wall facing the street.
Building Signs
Exterior signs should be located within the base of the building with concern for the appropriateness of location, size,
color, and lighting
Parking lot- behind the building
276
C. City/ Area: Loughborough Town centre Guide line Principles are:
1. Principles of Continuity and Enclosure:
Development should be in the form of secure perimeter blocks, which clearly distinguish between public fronts and private
backs, and follow a coherent building line.
Projections and occasional set-backs from the building line can be used to add emphasis, but the function of any space created
must be clearly defined.
The primary access to buildings should be directly from the street.
Developments including large stores and other ‘big box’ units, such as multi-storeyed car parks, can create exposed ‘dead’
frontages (the Bridge Street frontage to the Rushes is a local example). Careful design will be required in any future
developments of this nature to ensure the retention/creation of active and attractive street frontages, which are compatible with
the fine-grain of the Town Centre.
2. Building use:
All new development will be expected to consider the opportunity to encourage a mix of uses that contribute to the economic
and social ‘health’ of the area. Complementary uses can be mixed horizontally (side by side) or vertically (on different floors
of the same building).
Large development proposals should provide a mix of housing type, form and tenure. A compatible mix of uses should include
live/work units.
3. Special Features
A high quality design will be sought using layout, form, scale, massing, detailing and materials in the design of buildings and
external spaces appropriate to the character of the street, place and Town Centre in general. Design inspiration should be
sought from the particular local materials, building forms and features of character within the Town Centre.
New development should respect the historic street patterns, intricate grain, and vertical and horizontal rhythms (e.g. the
building widths, the proportion and scale of windows and doors etc.) of the Town Centre. Opportunities to repair street pattern
and grain where this has been lost, should be exploited.
Create a skyline which adds visual interest and conveys particular activities and concentration of uses.
277
• The main entrances to public and other major buildings should be emphasized through carefully designed streets, lighting,
signage and paving.
Existing important views and vistas should not be blocked or compromised by new development. In new development, the
opportunity to create new views and vistas that will contribute to the legibility of the Town Centre, should be considered.
• Development at strategic corners should emphasis their importance through the use of
building height, prominent entrances and other architectural features
•
Close attention to the detailing and quality of materials should be provided especially at ground floor and building entrances
that are very visible to pedestrians.
278
D. City/ Area: NOTTINGHAM CITY Guide line Principles are:
1. Building Height: 17 m to 26 m
2. Street Enclosure:
This unity of character comes from the consistency of street enclosure ratio in the centre of the city. The enclosure ratio is a
measure of the profile of the street. It relates the height of the buildings to the width of the street (expressed in this guide with
the height of the building first). In a street with a 1:1 enclosure ratio (such as Lister Gate), the height of the buildings is the
same as the width of the street. If the enclosure ratio is 1:2 (for example Mansfield Road), the height of the buildings is half
the width of the street. An enclosure ratio of 1:0.5 (for example Kings Walk), means that the buildings are twice as high as the
width of the street.
The main streets tend to have a 1:1 enclosure ratio, meaning that the predominant building height is the same as the
width of the street. This ratio increases on secondary streets that are narrower. Enclosure for diff roads should ensure
that the maximum heights of buildings do not overwhelm the Character of key streets.
a. Arterial routes 1:2
b. The Ring Road 1:1.5
c. High Streets 1:1
d. Secondary Streets 1:0.75
e. Minor Streets 1:0.75
f. Alleyways 1:0.5
The beauty of the city comes from its streets and public squares, and these would be nothing without the buildings that enclose
these spaces. The way, in which buildings enclose the streets, alleyways, parks and public squares of the city is known as its
urban form.
The most beautiful city in the world is nothing if its streets don’t throng with life and its buildings glow with activity. The
activity in a city is, therefore, at least as important as its design. This relates to the mix of different uses that bring people into
the city centre at different times of the day. It relates to the intensity of activity and the density of office and residential uses,
279
that determine how many people there are about. It also relates to the design of buildings and the extent to which they animate
the surrounding streets as well as the design of those streets, and the way they encourage vitality.
The strategy to maintain and increase activity in the city centre is based on three strands; increasing the density of
development around the fringes of the city centre, promoting a greater mix of uses, and ensuring that buildings spill their
activity out onto the street.
Arterial routes 1:2
Urban form relates to the way that buildings are positioned and designed to enclose public spaces, streets and squares.
E. City/ Area: Islington, London Guide line Principles are:
The height of street frontages should normally be in proportion to the width of the street
1. Street Enclosure:
Height also needs to be considered in terms of its proportion in relation to the size of the space it defines / encloses. The height
of a street frontage should provide sufficient sense of enclosure, natural surveillance and maximize the potential development
opportunity of a site. Most of Islington’s Victorian residential terraced streets have a height- to -width ratio of between 0.5: 1
to 0.7: 1.
280
Streets with a ratio of between 0.5:1 to 1:1 normally provide a well proportioned street frontage which provides a good
sense of enclosure. Anything less than a 0.3:1 height-to-width ratio can result in streets, which suffer from too little
enclosure where the buildings appear divorced from the street.
2. Special Features
Foot way design, Design of Street Furniture, Trees, and Accessibility for all. Nevertheless a
building that stands out can sometimes contribute positively to the urban environment by:
Becoming a focal point
Providing an element of surprise or contrast.
Reinforcing a sense of place
Highlighting the importance of a public building
The scale of a building is also determined by its bulk and width, and the manner in which
the façade is articulated. Historically, most of Islington’s street frontages are characterized
by narrow plot widths, where terraces are sub divided into plots, where the height is greater
than the width of the building.
The vertical proportions are expressed both in the overall dimensions and the individual
elements, especially the fenestration, and the manner in which they are composed within the frontage. The repeated pattern of
narrow street frontages of Islington’s streets creates a rhythm, harmony, and coherence.
Rooflines should normally respond to the articulation of the rest of the façade. It should normally be possible to read the width
of the plot divisions from the bottom to the top of the building. The roofline should reflect the rhythm, harmony and scale of
the longer street frontage. Stepped or sculptured rooflines can appear monolithic, particularly where the shape of the roof does
not pick up the sub division of the façade.
281
Window Shape, Position and Sizes
The windows are a key component of the façade, that help define a building’s character and provide underlying order as well
as its overall proportions. Care needs to be taken to ensure that the windows are of an appropriate scale to the façade, and that
each window in the façade has some relationship with the other. Key to this is identifying the appropriate shape, position and
size of the windows. Some elevations can be unduly monotonous, because of the number of repeated windows. The risk of this
is greatest in large façades, particularly when small windows are used, where they can appear lost within the elevation. Too
many different types of windows, particularly if they appear to have no apparent relationship to one another, can result in an
untidy façade.
Use of Materials
The use of materials needs to be considered both in terms of the relationship with the surrounding built form as well as the
articulation of a façade. Use of different materials can help to articulate and add interest to a façade. Facades can be further
articulated by employing recesses and projections that can animate a façade.
