Sustainable House Day

A major feature being orientation on the block which had the living areas facing the north so that heat gain during the day would be maximised to avoid artificial heating.

On Sunday 6th November several members of DRREA (Dandenong Ranges Renewable Energy Association) and EMFSUS (Emerald for Sustainability) visited several houses to view various sustainable features that people have incorporate dinto their houses.

There were both new houses and retro-fitted houses on the tour and talks given by all home owners on the features that had been incorporated into the houses.

The retro-fitted houses included adding insulation to walls and ceilings and foilboard under the floor to minimise heat loss. Also added was double glazing on windows and adding thick drapes and pelmets to hold heat in the house (or block it out in the summer).

A further feature was solar panels on north facing roofs with panels to view output from the panels as well as solar hot water systems.

Another feature that was shown was bushfire prevention precautions that had been taken with tanks and sprinkler systems as well as making sure there weren’t trees and shrubs and mulch too close to the house.

We saw several raised garden beds and an elaborate efficient composting system.

The 2 new homes had similar features with a major one being orientation on the block. Both houses had the living areas facing the north so that heat gain during the day would be maximised to avoid artificial heating. Both homes used minimal heating showing the advantage of smart house design in creating energy efficient buildings.

Eaves were added with dimensions designed to block hot summer sun but allow access to winter sun by taking advantage of the changes in the height of the sun from summer to winter. This was one thing having a major effect on the need to heat/ cool the houses.

All in all a very succesful day, tahnk you to DRREA, with everyone learing new ways to add energy efficiency features to their homes.
