- Well-Considered Approach to A Plan
This project was initiated on the basis of an urge to build up a scheme
of introducing PV power generation system for housing under the leadership
of housing industries complying with the important national policy
of "conservation of regional environment. In order to implement
this unique plan of installing the PV power generation system as standard
equipment to all the 71 houses in the complex, the following approaches
were taken:
- In consideration of harmony with the overall design of housing,
various parameters such as exposure to the sun, insolation, orientation,
roof slope and appearance were examined for individual houses.
- Each of houses is designed under the energy-saving specifications,
including paired glass, insulator arrangement and floor heating, aiming
at reducing the load of air-conditioning and improving the availability.
- Cost is reduced extensively, by as much as 20 %, through collective
purchase, concentrated construction works and revising construction
parts.
- PV modules installed on the top of roof serve as insulators, making
the temperatures of the attic "cool in summer, and warm in winter".
