Building an energy-efficient home is one of the most effective ways to save money by keeping your energy bills low. Therefore, make sure your builder is using the following materials to keep cold air out and hot air in during the winter and vice versa during the summer:
PIR Foam Energy Bricks
Straw and Stucco
Compressed Soil
Structural Insulated Panels
Vacuum Insulation Panels
Plant-Based Polyurethane Insulation
Low-Emissive Windows
Plastic Composite Wood-Substitute
Also, ensure your heating and cooling systems are in good condition and replace filters regularly to prevent the systems from working harder than they need to. After all, an energy-efficient home is a more cost-effective home.
