Passive home building refers to a collection of architectural ideas that combine the creation of comfortable interior living areas with a strict level of energy efficiency. This architectural idea, which has its roots in Germany, has spread throughout the world of construction as a way to reduce the energy required to heat or cool a structure and lessen the project's environmental impact. When comparing passive homes to conventional building stock, they may save up to 90% of the energy used for space heating and cooling and over 75% when compared to average new construction. In addition to passive energy-saving components like solar panels, well-placed shade, and well-insulated materials, passive home building employs architectural features like windows, flooring, and roofs that are intended to stabilise internal temperatures.

Radiant barrier

The shield panels represent the top-performing radiant barrier, which is designed to help block radiant heat from entering the home’s attic. Passive house supplies have demonstrated that the panels may block up to 97% of radiant heat, resulting in a 30-degree Fahrenheit drop in attic temperatures. These energy-efficient panels could also help you get lower HERS scores and energy codes. 

Air and water barriers

A tight building envelope is crucial to protecting your building and conserving energy. Passive house suppliers come with these panels equipped with a water-resistive overlay. Panel seams sealed with tape create the WRB system which eliminates the need for housewrap. This also helps avoid water intrusion and reduces air infiltration for a more protected and energy-efficient structure.

Thermally insulated sheathing

The thermally insulated sheathing combines OSB sheathing with continuous insulation to dominate heat loss and gain without the loss of R-value suffered by other foam insulation products as temperatures drop. R-values of passive house supplies, including foam, increase as temperatures drop. This type of insulation contributes to a more energy-efficient build. 

A vented attic with ducts buried beneath insulation and positioned above the bottom of the truss chords is a common choice among builders, as there are other insulating techniques as well. The main goal of passive house construction is to design your house for optimal efficiency. You also need to be equipped with the products that you need to stand up to the elements and help you achieve these standards.
