Building Performance Audits
How-To-Guide
Why do we do Building Performance
Audits?



Sustainable Initiatives is responsible for encouraging environmental
sustainability at UWA, including both sustainable teaching/research and
operations:

Managing carbon emissions from energy and transport

Water consumption

Waste and recycling

Fair Trade and sustainable purchasing ie paper
We look at operations from two different angles:

Building Performance

Workplace (Tenancy Performance)
Building Performance Audits give us the baseline data on our buildings

The Audits are done by completing a spreadsheet for each building

Different spreadsheets per type of room:

There are two main categories of lights:

Ceiling Light Fittings. Need to record:



Type of tube in the fitting (thickness)

T5s (1/2 inch)

T8s (1 inch)

T12s (1.5 inch).
Length of tube in the fitting


Energy - HVAC


How is this area heated/cooled?

Central air conditioning

Split air conditioning

Spill air

Heater

Fan
Central Air Conditioning vs. Split Air Conditioning

Central air conditioning has ducts in the roof (no temp control)

Split systems have a rectangular wall-mounted machine (w/ temp control)
Energy - Controls

How many light switches does the area have?

Does the area have motion sensors?

Does the area have A/C on/off push buttons?
Water - Taps

We look for 3 kinds of restrictors on taps:
Push Button Taps
Restrictor at Aerator
4.5L per min
Restrictor at Isolator
No Restrictors
15L per min
Water – WCs (Toilets)

Different toilets at UWA have different flush volumes. Distinguish by button:
Flusher Valves: 6L
(1 button)
Dual Flush: 3/6L
(2 buttons)
Turn Cistern: 4.5/9L
(turn handle)
Water - Urinals

Different Urinals have different flush volumes. Distinguish by shape:
Waterless
Caroma Cube
Trough (include
size)
Wall mounted
cistern
In-duct cistern
Waste - Bins

How many general waste bins does the room have? (Normally have a black
plastic bag in them)

How many recycling bins does the room have?
Internal Environment Quality

Factors that determine Indoor Environment Quality:

Number of occupants (=number of desks)

Lighting Quality

Are there external views?

Is there natural or borrowed light?

Are there window blinds or shading?



Comments?
