Introduction

When implementing energy efficiency techniques one must be aware of the possible solutions for energy use and the effective techniques that can be employed to provide better energy efficiency.

While some energy features add to construction costs, others can reduce costs. For example, increasing insulation and sealing air leaks reduces heating and cooling needs, allowing the use of smaller equipment and ductwork. The savings on the mechanical systems can help to offset the increased cost of additional insulation and air sealing. Energy efficient framing techniques can reduce lumber costs and prevent mold growth in outside walls and ceilings.
