Project summary
All houses of the Hills-Garden Kiyota are all-electric and using high-efficiency energy equipment such as a heat pump system, as well as PV system. The community realizes a low maintenance and operation cost, in addition to a low energy-consumption and low CO2 emissions. In total 142 PV rooftops of 2,4 kWp each have been installed.

Urban scale PV aspects
Hills-Garden Kiyota is located in the east of Sapporo-city, Hokkaido. The community is a residential area designed for the 21st century, aimed at a harmonization of “life”, “local environment” and “global environment”. Hokkaido is the most northerly in Japan, and the energy demand for heating and hot-water supply is larger.

Special PV project info
PV architecture and building integrationTo create a well-designed appearance of the houses and a harmonized streetscape as required by the community. As well, a high thermal insulation performance was designed for energy conservation.
Urban planning issues
Economical and financial issuesAfter starting operation, a net-metering scheme was applied so that surplus PV is traded between the inhabitant and the utility company, at the same price of the residential electric tariff.
PV ownershipBuilding owner: Inhabitant. PV owner: Inhabitant. PV energy user: Inhabitant.
Tariffs and metering
Info on grid issuesTo avoid negative influences against the grid network caused by a high-density of PV systems installed in a limited area, a precise negotiation with a utility company was implemented and the design of grid-connection was decided.
Other infoAll houses of the community were all-electric. A heat pump system for heating, a high-efficiency electric water heater and an induction heater (for kitchen) were used to realize a high efficiency energy system.
