Passive Solar House Design Principles

Passive Solar House Design Principles

A passive solar house design maximizes the efficiency and enjoyment of your home.

In our day and age, we are always trying to figure out how to maximize efficiency, especially in the construction of our homes. The passive solar house design one way to achieve the efficiency we are looking for, and the principles involved are ones that can easily apply to any type of house. Below are the design principles that make the passive solar home so well-made.

Orientation to the Sun

The position that the sun runs in relation to the house determines the lighting and heating of the space. The house should face not directly towards the south, but about 15 degrees or less off from it. Due to the high arc of the sun in summer and its lower arc in winter, a greater amount of solar energy, light and heat, will penetrate the house in winter, and less in the summer. One must have a thorough local knowledge of the site location to determine the angle of the sun’s rays. The landscape, such as shade trees near the house, will also affect the heating and light of the house. 


Passive solar homes are completely wrapped around in insulation for the best retention of heat or coolness. Like a thermos, the greater the insulation, the longer the house is able to hold its internal temperature. Of course, its main source of temperature regulation is the sun.

Airtight Construction

The construction of the home is also not just highly insulated, but built to be airtight. In any home, air filtration is the main reason why the heating and cooling bills go up. With little to no gaps anywhere in the build, plus all-around insulation, the house is able to retain the warm or cool air its inhabitants need. If the house is too hot, opening the windows at night can soon alleviate the issue. 


Because the house is so well insulated and airtight, the question of ventilation arises. How can fresh air circulate throughout the house? The placement of windows and doors helps facilitate airflow, while heating and cooling system needs vary depending on your climate. In any case, the need for larger HVAC units is unnecessary. 


With an emphasis on maximizing heating and cooling, windows too must be able to beat the heat and the chill. Double or triple-glazed, clear windows and Low-e windows are typical for the passive solar house.
