Site Planning & Passive Principles

by Wayne Congar , Founder & CEO of HUTS

Many of our clients ask how we incorporate passive principles into the design and specification of our homes. We discuss energy sources, like solar and geothermal. We discuss building science concepts and how to achieve airtight homes with precise and highly-insulated envelopes. We discuss low VOC material choices, high-efficiency equipment, the benefits of local suppliers, and choosing the right window package.

One of the highest impact decisions, however, has nothing to do with what we choose for the home build, but everything to do with where we place it.

The way a house is positioned plays a crucial role in its energy use. By smartly placing a house to take advantage of the sun's path, we can naturally heat the home in winter, using the sunlight to our advantage. This means less reliance on artificial heating, which saves energy. Additionally, careful orientation and use of landscaping can provide shade during the hotter months, reducing the need for air conditioning.

Materials also play a part in this energy-saving strategy. Using substances that absorb and store heat from the sun during the day and release it slowly at night can help maintain a comfortable temperature inside the house. This approach, known as thermal mass, is a key element of passive design that contributes to a home's energy efficiency.

Finally, positioning a home to catch natural breezes can significantly reduce the need for mechanical cooling systems like air conditioners and fans. Strategic placement of windows and doors can enhance cross-ventilation, leveraging the natural airflow to cool the home. Combining these elements—solar gain, thermal mass, and natural ventilation—not only reduces energy bills but also contributes to a more sustainable and environmentally friendly home.
