Dwellings designed along the principles of passive solar gain do not require mechanical means to gather and utilize the sun’s energy and enhance their ventilation (Sustainable Sources 2011b). According to the California Energy Commission (2011), by designing a house to take full advantage of the sun’s heat, energy consumption can be reduced by 30 to 40 per cent. Despite appearing to be simple, design for passive solar gain requires careful attention to details and application.
The two key aspects that need to be considered in passive design are the dwelling’s exterior and interior. For the former, it is important to site the house properly and account for seasonal changes, solar cycles and local vegetation, ...
