Climate

Every region in New Zealand has its own local climate, and every site within those regions has its own microclimate.

To commence each project, AM Architects will carry out a Site Assessment to check seasonal temperatures, sun and shade angles, prevailing winds across seasons and how they are impacted by the fall of the land, vegetation and other buildings.

The Site Assessment will inform the best location for the home on the site, building orientation and form so it is able to perform efficiently within its local context.

Orientation

How the house is positioned on site, and in relation to the sun will determine the potential for access to sunlight and shade.

The direction & angle of the sun changes through the seasons and impacts the internal temperature of a home, and can also allow for changes in quality of light which in turn influences the potential use and feel of each space.

In New Zealand, main living areas are ideally positioned to the north to maximise sunlight. The eastern part of the home will receive low morning light, and the west typically hotter, more intense sun that will reach deep into the buildings interior. The southern elevation won’t receive any direct sunlight so typically windows are minimised to reduce heat loss.

Scale

Bigger is not always better in sustainable design. It is important to consider the scale of the home that is being designed and to interrogate the size and number of rooms desired. Is it imperative that a home includes a 3 car garage, a third ensuite and a 5th bedroom than only gets used once a year? Reducing the size of a home reduces construction cost, energy use, materials and allows for greater outdoor space.
