eNeRgY eFFIcIeNcY glAZINg PROvISIONS FOR bcA vOlUme TWO
The ABCB has prepared a document
to explain the changes to the Volume
Two glazing provisions introduced
with BCA 2010. The document covers
many of the issues that practitioners
are experiencing when attempting to
design a complying glazing solution
using the elemental Deemed-to-Satisfy
provisions in BCA 2010, especially for
buildings in the cooler climate zones.
Topics include:
• glazing basics;
• the importance of window ratings;
• the new conductance calculation;
• exposure factors;
• changes to the glazing calculator
layout;
• advanced glazing calculator
techniques; and
• glazing in alterations and additions.
One of the biggest changes is the new
conductance calculation for climate
zones 2 to 8. The allowance in these
climate zones is no longer based on
floor area. The calculation is best
thought of as “winter performance”, and
aims to ensure that the total heat lost by
conduction through the glazing will not
exceed the direct solar gains available.
The “winter performance” is affected
by both the Total U-Value and the SHGC
of the glazing, so it is very important to
optimise the SHGC for both winter and
summer conditions.
The document is available on the ABCB
website.

8 • Australian Building Regulation Bulletin
Your opportunity to hear about
the National Construction Code
from the experts
The Australian Building Codes Board will
take the first step in delivering the National
Construction Code (NCC), when it publishes
the Plumbing Code of Australia (PCA) as
Volume Three of the NCC, for the first time
in 2011. It is expected that future editions of
the NCC will eventually comprise all on-site
construction regulation (building, plumbing,
gas, electrical and telecommunications). The
implementation of this national policy initiative
will improve regulatory consistency across
jurisdictions and deliver benefits for both the
industry and community.
The 2011 National Seminar series will play
an important role in raising practitioner
awareness of issues associated with
the launch of the NCC and other code
amendments scheduled for 2011. The
seminars will be divided into two sessions,
which will provide an opportunity for
practitioners to hear about relevant aspects of
the consolidated code and how it will affect
their work.
BCA Seminars, 9.30am – 12.30pm
As with previous years, there will be half
day seminars in all capital cities focusing
on changes to the BCA, including the new
disability access provisions.
PCA Seminars, 2.00pm – 4.30pm
The ABCB will also be conducting seminars
in the afternoon at the same venue, that will
focus on the release of the new 2011 PCA
and what implications the NCC will have.
The registration fee will include a copy of the
2011 PCA and other relevant materials.
Don’t miss out – the National
Construction Code will be introduced
on 1 May 2011*
*PCA adoption dates may vary in some States & Territories
Please note that the BCA and PCA sessions
are being conducted independently and a
separate registration form must be completed
for each seminar.
Visit the ABCB website from mid-November for registration details www.abcb.gov.au
