IN OUR DESIGNER HOMES
The importance of passive design cannot be overstated.
Paying attention to the principles of good passive design suitable for your climate effectively “locks in” thermal comfort, low heating and cooling bills, and reduced greenhouse gas emissions for the life span of your home.
Use natural sources of heating and cooling, such as the sun and cooling breezes, achievable by appropriately orientating your building on its site and carefully designing the building envelope (roof, walls, windows and floors of a home).
Well-designed building envelopes minimise unwanted heat gain and loss (Source Australia’s guide to environmentally sustainable homes).
Design openings to bring in daylight without direct exposure to the sun and also to catch breeze for internal spaces ventilation. Let’s not forget that landscape is one of the important elements used to provide protection from the heat and direct exposure.
What keeps you comfortable that is not air conditioning, heating or insulation?
It is Phase Change Materials. Using phase-change floor and wall materials with thermal mass property finishes (tiles or concrete floor) keeps the temperature cool in summer and warm in winter. Phase Change Materials store and release heat or cool air, all the while retaining a near constant temperature. They do it up to a dozen times more efficiently than other “thermal mass” mediums, such as water and masonry. And they keep doing this for decades, with no power input or maintenance.
