A solar heating system was designed for a private home in Jerusalem, with the goal of economizing on energy consumption and ongoing expenses.  In general, the architectural design of the house took elements for collecting, storing and distributing solar energy into consideration, as well as appropriate thermal insulation.

The Ministry of National Infrastructures recognized this system as a demonstration facility for energy conservation and assisted in its construction by means of a grant constituting 30% of the investment.

The goal of the project: Utilization of solar energy for home heating in Jerusalem.

The course of the project: The construction of a passive solar heating system, comprising a greenhouse, air collectors and a Trombe wall, and the construction of unique floors and ceilings for storing solar energy and radiating it into the interior of the house at night.

The result: An annual savings of 6,500 kWh in energy and electricity
