"I hired Albana Roofing to replace the Soffit and Fascia on my house. It's a family-owned company and everyone was super nice and very knowledgable. They did a great job, arriving at 8:00 am each day to work a full day. They even worked on Saturday to get the job done quicker. I recommend them and would hire them again in the future."

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage.

Many builders offer energy-efficient upgrades as part of the design process.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation.
