Minimize heat gain
CONCLUSIONS FROM SITE MICRO-CLIMATE ANALYSIS SITE OPPORTUNITIES
•Small footprint of building
-EXISTING SERVICE ROAD •Skewed south façade for maximum solar gain -LOW WIND INTENSITY •Spatial mapping according to climatic needs of each space
-EXISTING PARKING FACILITIES
•Highly insulated envelope ( U value < 0.12W/sq.m °C)
-EXPERIMENTAL FORMS OF SURROUNDING BUILDINGS SITE CONSTRAINTS -IRREGULAR SHAPE OF SITE -NO SITE FRONTAGE -DOMINATING SURROUNDING BUILDINGS

GROUND SOURCE HEAT PUMP
•1unit of electricity produces 3-4 units of heat •Depth of trench : 2-3m below ground level •A trench of about 10m length provides 1kw of heating load
•POWER REQUIRED – 1,46,000KWh/yr •POWER GENERATED USING 115sq.m of solar panels – 12,765kwh/yr (10%)
MVHR HEAT PUMP SYSTEM •A supply fan and duct system provides fresh air whilst an extract fan and duct system exhausts stale, moist air •Heat exchanger is used to transfer heat from the exhaust air to the supply air
