Solar Thermal System in Buildings in Japan (2008)

This presentation was made by Mr Mitsuhiro Udagawa, Professor at the Kogakuin University in Tokyo, Japan, during the Asian Workshop on Energy and Environmental Technologies which took place in 2008.

The presentation includes many visuals showing the evolution of solar thermal system installations in households and other buildings in Japan over the years (1974, 1985, 1999). It is possible to see the evolution of both technology and design.

Recent trends point towards hybrid systems, mixing different technologies. Japan is missing standards in design of systems and evaluation of design methods. The payback period is still considerable, so further incentives are needed to develop the market.
