A passive house is a home that aims to improve the energy efficiency of a home so that it can be lived comfortably without relying on air conditioning or heating equipment.

By efficiently utilizing the sun's solar energy, indoor heat generation, and heat recovery through the ventilation system, there is no need for heating equipment even during the coldest winter months.

We aim to maintain the minimum amount of air conditioning even in the summer by making good use of solar shading and heat storage.
