Plot the sun path and sun angles across the site at different times of the year and use this information in the design.
Orientate the house along an east-west axis.
This will maximise the amount of wall area exposed to the north. Careful design is important, as homes in Auckland can be more prone to overheating than loss of heat.
Maximise glazing and any shading devices or roof overhangs on the north facing wall.
This allows for winter sun and summer shade. Use a reduced area of glazing on south facing walls.
Consider how different rooms will be used during the day.
Plan the house accordingly around this to maximise the benefit of sun throughout the day.
Use pergolas, deciduous trees and planting in open spaces on the north of the site.
This will provide shade in summer but allow the sun’s warmth in winter. Consider using evergreens in open spaces to the south to offer all year round protection from the wind.
Place heavy and hard surfaced ‘high thermal mass’ floors in rooms exposed to winter sun.
For example an insulated polished concrete floor slab in rooms exposed to winter sun. These will store the sun’s heat and release it within the house.
Provide for solar panels for hot water or electricity.
A north facing sloping roof is the most efficient place to locate panels.
Locate and shape the building so its north side receives sun between 9am and 3pm in winter.
