ENERGY SAVING FEATURES

Passive Design:

• Limited west and east orientation

• Reduced window-to-wall ratio (only 13.29% of WWR on

east/west facades)

• Natural ventilation for the canteen building

Building Envelope:• Low-E glazing for office area with SHGC = 0.55 and

corridor used as buffer between glazed façade and

office rooms

• Roof assembly made of aluminum bubble foil and metal

sheet with solar reflectivity of 0.659 and thermal

emissivity of 0.82. Above office space, an air

• Walls made with concrete blocks achieve a U-value of

1.767 W/m2.K.

ENERGY SAVING FEATURES

Building Cooling:• Use of evaporative cooling (with cooling pads) for manufacturing facilities and warehouse

• Use energy efficient split-units in office • Use natural ventilation for the canteen

ENERGY SAVING FEATURES

Artificial Lighting:

Only 2.42 W/m2 of installed LPD with efficient LED lighting installed.

Renewable Energy:

72 solar PV panels of 345 Wp = 24.84 kWp

37,400 kWh/yearproduced by solar panels

WATER SAVING FEATURES

Water-efficient fixtures:

• WCs: dual-flush with flush volume of 3 / 4.8 liters per flush

• Urinals: flush volume of 1 liter per flush

• Taps: flowrate of 2 liters per minute

Water-efficient landscaping:

• Native species installed.

• Irrigation demand 100% covered by non-domestic water

Non-domestic water use:

• Rainwater harvesting

• Reuse of treated wastewater that can be used as domestic water (meet water quality requirements
