INTRODUCTION OF PATRAS
-The third largest urban area of Greece, in northern Peloponnese-Is built in the foothills of Mount Panachaikon- Urban geography : division into upper and lower sections
INTRODUCTION OF PATRAS
CLIMATEMediterranean; Mild, wet winters and hot, dry summersSpring and autumn : pleasant transitional seasons
EXAMPLES OF ARCHITECTURE First Building
Current Condition : GoodSuggestions for renovation : •Replacement of the openings (but keeping the same style)•Probably replace the roof •Put insulation for the thermal bridges•Repair the barriers•Put some shelters above the windows •Repaint the facade
EXAMPLES OF ARCHITECTURE Second building
Current condition : Very badSuggestions for renovation : •Remove the damaged materiels of the walls•Put a new surface• Internal insulation•Replace all the openings (keeping the same style)•Build a new roof•Repair the barriers•Probably put solar pannels on the top of the building for energy saving
EXAMPLES OF ARCHITECTURE
EXAMPLES OF ARCHITECTURE
Third building :
Current condition :Very badSuggestions for the renovation :•Repair mostly the side walls of the building•Repair the openings by putting double glazing on the same frame•Reconstruction of the roof•Possible internal insulation
PROJECT OF THE VILLA
BASIC IDEAS
Keep it simple Keep it cheap, efficient Renewable as much as possible Use original components
INTRODUCTION ABOUT THE VILLA
Plan of DesignBuilder
PROBLEMS
insulation Uninsulated walls Uninsulated roof Wooden doors One glassing windows Uninsulated basement
PROBLEMS
heating / cooling system Bad Insulation of the pipes Circulation pump in a bad shape Heat boiler is damaged and too expensive Lack of space for Fan Coils
PROBLEMS
heating / cooling system
PROBLEMS
domestic water system 100l Electric boiler
PROBLEMS
ventilation Uncontrolled supply and exhaust air amount
SOLUTIONS
insulation1. Roof insulation Options:
Insulation to the whole ground; Insulation between the beams on the roof; Insulation around the ground and the room;
Which materials are possible? Glass wool
Strawbale
Wood fibre
SOLUTIONS
Reasons for the strawbale Easy to find Low Cost of straw: 3 €/m2
High performance: λ= 0.045 W/m*K High humidity resistance Very good fire resistance
SOLUTIONS
Windows insulation options
SOLUTIONS
Reasons for the secondary glazing Want to use original components -> no
change in exterior appearance High thermal insulation Very good U-value= 1,7 [W/m2*K] Cost per window: 150 €
SOLUTIONS
Doors options Replace the door with a new one with the
same style Improve the original door with self-stick
foam to the frame of the doors Decision : second option because it’s
cheaper and easier to install
SOLUTIONS
Basement Options Mineral wool Wood fiber
Reasons for the mineral wool: It’s cheap material Good insulation properties Thermal conductivity only 0,035-0.05 W/m2*K Resistance against mold Good noise insulation
SOLUTIONS
Walls Thin material to preserve the original room
size Should be breathable and compatible with
the original wall material Avoid any cold bridging
SOLUTIONS
Advantages of wood viber The thermal capacity is more higher than of
mineral wool Protect much better against summer heat It supports uniform interior climate It’s easy to install on the wall It’s ecological material It’s cheap
SOLUTIONS
calculation for insulation’s cost
SOLUTIONS
heating/cooling system
insulation for the pipes Material: mineral wool Thickness: 3cm Cost: 15€/m2
SOLUTIONS
circulation pump Type: Wilo-Stratos 30/1-12 Power: 200W Energy and money saved:
Qbefore=1620kWh/a
Qafter=432kWh/a
Saved: 178 €/a
SOLUTIONS
heating with a heat pump Energy and money saved:Diesel –Boiler :
2230 Liter/a DieselCost = 3100€/a
Heat pump:PHP=6300 kWh/a
Cost=900€/a
Saved: 2200€/a
SOLUTIONS
New Fan Coils Wall Fan Coils in the rooms (except hall)
SOLUTIONS

SOLUTIONS
ventilation Air vents in a top of the windows
ELECTRICAL SYSTEMS OF THE VILLA
System is very old and has been built in small steps No clear plan for protection No documentation
System is running when it is not needed Lighting, computers, heating and cooling
systems
CURRENT ELECTRICAL POWER USAGE About 12 computers approximately 500
W each Six lights for the hallways, one light per
office and lights in other rooms 12 – 40 W each
Heat pump, appliances and other electrical systems
All evaluated individually and total energy usage calculated annually ~ 36 000 kWh
SOLUTIONS FOR FOUND ISSUES
The main goal is to cut down unneeded power usage Lower energy use
The total used electrical energy is , where P is the power of the system and t is the time it’s used P’ < P t’ < t
Villa needs better electrical appliances and smart control for the systems of the house
THE LIGHTING
We chose LED lamps for the villa : Easy to install Efficiency Lifespan Low consumption
THE LIGHTING
Approximately 12m² Original fixtures Fit LEDS 700 lumens per
lamp 7 watt per lamp
Approximately 16 m² One flat LED panel 1500-2400 lumens Possibly work lights Maximum : 20W per
office
Hallway Offices
THE LIGHTING
One big office Approximately 20m² Two hanging
decorative LED fixtures : 2000 lumens (close
to center) 1000 lumens
(towards the corner) Possibly work lights
(maximum 20W)
Staircases Indirect LED lighting : on
the corners of the ceilingBathroom : Discrete bathroom LEDS 500 lumens 300 lumens (3)
Attic Two lamps 500 lumens (2)
CONTROL
The idea for the control of the house is to only run systems when they are actually needed Heat/cool and light the offices only when
they are in use Install a main computer and necessary
sensors Plug in office hours and monitor office
use with possibly RFIDs Doable very cheaply!!
CONCLUSION FOR THE ELECTRICAL SYSTEM
System is NOT SAFE! Protection might not work could cause a fire
Peak power can be cut down by installing better lighting Good for the working atmosphere Pretty cheap
Time of use can be cut down by better control of the relevant systems
