Has Hardly Advanced Since the 1950s

THE
Heat
Transfer
Problem
Homes gain
and lose heat
in many waysDuring Summer
homes become hotter
as unwanted external
heat transfers
into the home
In Winter the
opposite occurs
and wanted heat
transfers out
resulting in a
colder home
What Is
Heat Transfer
Heat transfer describes
a natural occurrence
where thermal energy
transfers from hotter
substances bodies or
spaces to colder
substances bodies or
spaces
It occurs when
substances bodies or
spaces are in thermal
contact with each other

internal heat is

the outside
Notice how the
wall is far more
effective than the
double glazed
window at reducing
heat transfer

Thermal Imaging
Australians mistakenly
believe double glazing
is the best standard in
window technology
Though double
glazing exceeds the
performance of framed
and double brick walls
it cannot equal the
performance of the
insulated thermal
mass wall built
around it
You can see the heat
transferring through
the double glazed
window to the outside
Sub-Standard
Ceiling
Insulation
Missing and poorly
installed insulation
in an Australian
homeIf your focus is on
lower pricing the
quality standard is
usually reduced
Questions To
Ask If you
want a Low
Energy Home
Are the building materials a
part of the solution or the
cause of the problem
Are basic building and
design methodologies being
used - The majority of double brick
homes are only single
brick at the hottest
part of the home - hardly
intelligent
Are you addressing all
points of thermal contact
vulnerability in the
building envelope
Energy

Home
The standard Australian
double brick or framed
home built today
is NOT energy efficient
A home built utilising

The Total
Building
Envelope
Energy efficient low

the performance of
external components
known collectively
as the building
envelope
The envelope
includes the slab

and roof working
cohesively to protect
the occupants
against heat transfer
and air leakage
Strength and

Frequently Asked Questions
Does it cost more to build?
Yes of course it does. How much more depends on the choices you make. An energy efficient home can be built for the same budget of a larger inefficient counterpart, providing you reduce the size of the home.
Will an energy efficient, passive home save me money?
Yes, once you move in you won't need to purchase, install and maintain expensive products that attempt to reduce heat transfer. Your homes lifetime ongoing daily running costs will be significantly reduced.
Can I make my home energy efficient once it's built?
Reverse engineering is less effective than implementing energy efficiency at the design stage.
Does it take longer to build?
Whilst some parts of the process can be faster than more traditional building methods, the simple fact is that when you build with an intelligent methodology that has far greater attention to detail it will take more time
Does an energy efficient home have better resale value?
It's most likely that your resale value will far exceed average market prices simply because prospective purchasers will notice the comfort difference as soon as they walk inside.
