How do many Canberra homes perform?
In winter – turn the heating off, and the home looses heat quickly.
There will be little insulation, and the heat will radiate or move out of the home.
There will be air movement or leakage in all house surfaces,
and your warm air will be removed from your home.
Most homes get little winter sun into the inside of the home,
and get little natural heating.
Some times its colder inside the house then it is outside.
A lack of light may also make it dark inside.
Unfortunately, this describes many homes, and the result can be depressing.
Heating costs will be high, comfort will be low.
How does an Energy Efficient Home work?
If you put a hot cup of coffee on a outdoor table in the middle of winter,
the coffee goes cold quickly.
If it was in a thermos, the coffee would stay hot for some time.
If the thermos worked “perfectly”, the coffee would not get cold.
That’s the theory. Now let’s use it.
If we could have a perfectly insulated building envelope,
i.e, floor, walls and ceiling, we wouldn’t lose any heat?
We also need the building envelope to be air tight,
So we don’t lose our heated air.
If we can face many windows to the north, and get the sun to the interior,
we can gain some heat into our building envelope.
It is common sense, not rocket science,
yet it is rarely done as Canberra will testify.
How we build an Energy Efficient Home
We have gained many years of experience with all the critical processes
needed to build a high quality energy efficient home.
A clear understanding of what works and how it works is needed to achieve
the high performance we are after.
We know it is achievable, we are building energy efficient homes now.
