....we should be able to avoid the need for heating the house for the vast majority of the year.
In Auckland we are lucky enough to have a temperate climate, making energy efficient building design fairly simple. A house that is comfortable all year round can be achieved with reasonable levels of insulation, reduced thermal bridging, summertime shading features and ventilation. The envelope of a house (i.e. walls, roof, floor and windows/doors) is a very important element of the design as it can have a huge impact on the energy performance of the building and the health and comfort of the occupants.
Thermal modelling of our preliminary design shows that with adequate insulation and high performance windows we should be able to avoid the need for heating the house for the vast majority of the year. The high insulation levels will result in uncomfortably high temperatures in the summer without adequate ventilation and shading which we will address through opening windows, eaves and other shading devices. This level of thermal performance has been demonstrated on projects like the Now House1 which only needed heating for two days last winter.
Design Opportunities Matrix
The matrix below shows the key design considerations related to the building envelope in the left column and the project goals listed along the top. The coloured boxes indicate the goals that the design considerations contribute towards. The matrix is colour coded as follows:
- Indicates that the design feature has a positive effect on the goal
- Indicates that the design feature has a negative effect on the goal
- Indicates that the design feature can have a negative or positive effect on the goal
The sections of the website listed in the top menu bar are evolving and details on the design initiatives will be added to these sections as we develop the design and build the house.
