Otago St Clair Dunedin Certified, Passive House Classic


This amazing home sits south west over the coastal view.  The architects had to solve the issue of being able to enjoy the vista while enabling some shelter from the prevailing winds. Super insulation was used along with Triple argon filled low-E coated glazing necessary for the climate this far south. European windows by ecoWindows in wood and aluminium also feature. This grid tied photo-voltiaic home is perfect for this progressive family, often generating more energy than it uses.

Extraordinary heat energy savings.

Every one of our projects are energy modelled using the Passive House Planning Package (PHPP). It's through this powerfully clever tool that we can accurately calculate just how much heat energy every eHaus will save when compared to a similarly- sized typical new home, built in the same climate region.

This project is making significant carbon savings for a better environment.

We believe that our homes should have a big impact on the way we live, but little impact on the land. We've calculated the amount of carbon our homes have saved through energy efficiency from move in day 'til now. At their core, eHaus' are built with the elimination of carbon emissions in mind - so we're not only creating healthy, comfy & high performing homes, but spaces that don't cost the earth.
