Energy Conservation

Welcome to
Energy Conservation

In 1973 the world experienced the first oil crisis where the price of oil skyrocketed dramatically. There where 3 oil peaks in the 70's. Back then oil was used to heat homes, many homes had oil space heaters.
An oil tanker would pull up outside the homes and oil was pumped through a long hose into a tank that was adjacent to the side of the house. As the price of oil became out of the reach of homeowners and the need to conserve energy became
widely acknowledged, this form of home heating was phased out and replaced with gas. The Newspapers at the time where constantly urging homeowners to conserve energy and recycle. This was accompanied by massive advertising campaigns promoting Batt type insulation for ceilings of existing homes.
These Batt INSULATION companies soon found they couldn't keep installers employed as they where becoming sick from the highly irritant Batts.
This resulted in them taking on a new approach, Do It Yourself advertising campaigns flooded the newspapers and tv. These ads were highly gimmicky such as "pretty pink", "the roof fairy", "the pink panther" etc and all they said about the insulation was that "Its Easy, you can do it yourself and save".

With The general public at the time being keen to conserve energy, they didn't question these types of adds.
Back then the attitude was that "if its on tv it must be ok". Consequently millions of Australian homes where done by Do It Your-selfers, who later where to remark "NEVER GAIN, had to throw my clothes out i couldn't get the glass, and was itching for days.

Homeowners were unaware of the need to wear a mask and protective clothing as this type of fiberglass was highly irritant and dangerous to the respiratory system, eyes and skin. Also homeowners were unaware that the performance could be reduced considerably
by gaps and spaces in the insulation. With batts then being only half of today's recommended thickness it resulted in the vast majority of homes being very poorly insulated, not a good way to conserve energy. It wasn't until 1984 that a CSIRO information sheet about types of insulation stated:

"What is required for good performance?"
The first essential for good performance of ceiling insulation is that the insulation be applied without gaps otherwise the thermal insulating effect can be reduced considerably.

Even today, with all the various obstacles up in the roof, avoiding gaps and spaces in Batt type insulation is virtually impossible and is not a recommended way to insulate the ceiling of an existing home.

During the 70's, a stand out article that appeared in the Melbourne Age Newspaper quoted "the then" lecturer in architecture at Melbourne University, Dr Alan Coldicutt, describing all the various ways to keep the heat in in winter, and out in summer. The journalist dubbed it "The Thermal Home".Since then, more ways to conserve energy in the home have been developed. To see the modern version of retrofitting existing homes,
