A passive solar home is unique due to the fact that essentially every element of the home is used to collect energy and distribute it evenly throughout the home. This includes the floors, roof, walls and even the windows. The only way these passive solar homes can be effective is by the careful and thorough design by a structural engineer. Everything from the area you build the home at, the materials, the base structure and more all combine to make a passive solar home useful. Here are some things to consider about structural engineering and passive solar homes.

Factors To Consider For Passive Solar Homes

The sun doesn’t have to shine around the clock in order for passive solar homes to work, but these factors are essential:

  • Location on the land you’re building on. By building the home on the northern side of the lot, the southern end of the home will have the clearest possible view of the sun.
  • The structure itself. Your structural engineer will tediously design the windows and walls to ensure they are exposed to as much sunlight as possible. Some windows should allow sunlight in, while other surfaces on the structure should absorb the heat to store and use at a later time.
  • Design materials. The most common materials used in passive solar homes include brick, tile, stone and concrete. These are the best thermal mass materials since they absorb and store heat from both the inside and the outside to be used at the appropriate times of the year.

Challenges When Designing Passive Solar Homes

From a structural engineering perspective, the main challenges of designing a passive solar home include ensuring the home is air tight and is structurally stable. Most passive solar homes will have a larger ratio of windows on the southern side of the building, which means there will be fewer structural shear walls on that side. In order to prevent damage to the windows because of the stress placed on them, trimming beams are usually specially designed to give them additional strength.

Collaboration And Comprehensive Analysis is Essential

A structural engineer must work closely with the design team and any other contractors who are working on a passive solar home. Since there are so many different nuances and various components to these homes, every detail is critical. Every good structural engineering company can take the lead in ensuring the home is designed and constructed safely and will be as effective as possible.
