On previously developed or graded site, restore or protect a minimum
of 50% of the site area (excluding the building footprint) with native or
adaptive vegetation. Native or adaptive plants are plants indigenous
to a locality or cultivars of native plants that are adapted to the local
climate and are not considered invasive species or noxious weeds.
Applicable to landscaping on rooftops and roof gardens so long as the
plans meet the definition of native or adaptive vegetation. Total Site Area = 12,046 m2
Building Footprint = 3,334 m2
Balance area = 8,712m2

● Implement an Erosion & Sediment Control (ESC) Plan
● Proper site management of surface water run-off treatment.
● Increasing or improving ground surface infiltration.
● Elimination of contamination sources.● Proper handling of contaminants and disposal.
● Removing pollutants from storm water run-off.
● Provision of silt-traps prior to final discharge to exist drains and waterways.

STRATEGYTo recover condensate water into a/c make up tank
Condensate water recovery (accounting for at least 50% of total
AHUs/FCUs for use as cooling tower make up water etc
Estimation of Condensate water generation.
Latent heat = mass of water x heat of vaporisation
H = m x L
Base on 1445kW(411RT) cooling load, 20% goes to latent heat.
The heat of vaporisation is 2438kJ/kg, to condense vapor into
water.
Hence, the generated condensate water is estimated to be
Q (l/s) = 1445kW x 0.20 / 2438kJ/kg x 1 L/kg = 0.12 L/s
Daily condensate water generation = 0.12 L/s x 3600 s/hrs x 10
hrs/day x 0.8DF = 3456 Liter/day (3.5m3/day)
