The Earth is heating up and global warming is conspicuous today. Carbon dioxide (CO2) gas generated by the burning of fossil fuels and the forests and it is responsible for about half the greenhouse gas warming. Notably, the energy used to heat, light and run our homes accounts for 27 % of all the CO2 emissions in the UK. One of the most promising renewable energy technologies is a solar photovoltaic (PV) power generating system that can be integrated into today’s homes. This paper identifies design, production and marketing approaches being applied successfully by Japanese housing manufacturers for the commercialisation of their PV solar homes. As well, this analyses housing producers’ perception or emotional attachment to such innovative green houses by documenting their experience of participating in the Japan Solar Photovoltaic Manufactured Housing Technical Mission that was organised in 2006 by Natural Resources Canada, where the author acted as the mission coordinator. This study may provide guidelines on how to increase the number of early adopters of PV solar housing and how to commercialise such homes that conventional homebuilders and housing manufacturers are often not familiar with.
