WATER USAGE

Only 20 per cent of the water is used for drinking, cooking;

Over 60 per cent is used for bathing, washing and flushingdown the toilet. Important that our water toilets are still 10-12 litres per each pull of the chain.

Literally, water down the drain

...80% potable water ends up as waste-water


IN COMMERCIAL BUILDINGSq Major Water consumers are

n Plumbing (Flow / Flush Fixtures)

n HVAC

n Landscaping

q Thus efficient use of water can lower water use fees, lowersewage volumes to treat etc. and thus lower capacitycharges and limits

q Technologies are available to treat gray water, harvest rain

water and use treated water for landscaping / flushing etc.

q Potential to reduce water consumption upto 30%

Intent

v Verify and ensure that fundamental building elements andsystems are designed, installed and calibrated to operate asintended

Requirementsv Engage Commissioning Team,

Can be from project team but not responsible for design

v Develop and implement commissioning plan


qWHY COMMISSIONING?

v Commissioning is a quality based method

v It is owners means of verifying that the planning, design,

construction and operational processes are achieving their

goals

v It ensures delivery of high quality building with maximum

asset value




43/106


q A commissioned building provides

v Optimized energy efficiency

v Indoor Air Quality

v Occupants comfort

v And thus sets stage for minimal operation and

maintenance cost



Properly executed commissioning process often increases

energy efficiency by 5% - 10%


q LEED focuses on systems and assemblies having to do with

projects operational performance particularly those related

to LEED pre-requisites and credits

q HVAC and their associated system

q Building Management System

q Lighting systems

q Renewable and alternative energy technologies
