Let’s be honest, Dunedin may be a fantastic place to live but it isn’t the warmest place on earth. Finding a warm, comfortable home even among Dunedin’s new housing stock can be really hard and even when you are able to find one, there are serious ongoing heating costs to consider, not to mention windows dripping with condensation.
Surely in 2017 we can do better than this? Well, we can.
Early in the planning of the High Street Cohousing project the group made the decision to pursue the international Passive House standard for the construction of the new homes. The Passive House standard is the international gold standard for indoor health, comfort and energy efficiency.
The principle behind Passive House is simple – you can either build a home which leaks heat and spend the rest of the life of the building trying to replace that heat; or you can build it right in the first place and it will remain warm and healthy for the life of the building.
All Passive House buildings are carefully designed to maintain an internal temperature of between 20-25oCelsius all year round with little active heating or cooling. There is no condensation, no drafts, no cold surfaces and a constant supply of fresh air to all parts of the building. All this while reducing space heating energy demand by around 90%. These are the homes of the future and we are going to see a lot more of them.
