Let the Sun shine in. The most efficient and effective way of heating your home in cold climates
is by using the natural energy of the Sun as much as possible. Letting the Sun shine into
living areas and naturally heating the internal envelope of thermal mass within the
building will most effectively stabilise internal temperatures and therefore create
a home that is comfortable all year round with little or no artificial heating.

In regions such as the South Island of New Zealand, the use of passive solar designs in homes
makes a lot of sense. The use of maximum insulation, thermal mass and daylighting where
appropriate help to make a home more livable. Correct orientation to the north to allow
maximum "solar gain" in winter and minimum in summer and the use of mechanical devices
such as solar hot water and shade sails all help to regulate your environment in a manner
which is low-energy and therefore with a lower greenhouse gas intensity ie: less carbon dioxide
into the atmosphere. Efficient lighting, the use of low-energy appliances, waste-minimisation,
the adoption of photovoltaic electricity, the incorporation of Trombe walls or the integration
of natural ventilation, are all positive ways in which cold climate houses can become more
energy efficient. There are many ways we can live more efficiently and therefore more
sustainably - and it can actually benefit our lifestyle, not hinder it.
