DESIGN: This is where the process of creating an energy efficient building must start.
How to be environmentally conscious and what to consider before you begin your project:
When determining a sustainable design, it will be necessary to consider the following
Energy and CO2 emissions
The thermal efficiency of a building is its ability to retain heat. The ultimate
goal in building design is passive, (a passive house is a building in which a comfortable
interior climate can be maintained without active heating and cooling systems) which
utilizes design features to make a building more climate responsive and energy efficient.
It involves various strategies which take into account factors such as climate conditions,
sun position, seasons, wind speed and direction, seasonal humidity and combined temperature.
There are numerous aspects to consider in achieving a truly passive design, some
of which may be extremely difficult to incorporate into a new build or an extension
to a building within the confines of a city. However, the most relevant considerations
· Compact form with efficient insulation
· Orientation and solar gain
· Design which minimizes the area of perimeter walls
