A Survey of Advanced Residential Building Techniques & Technologies and Their Impacts on Energy Codes

There is a distinct lack of knowledge on commonly used building practices that save energy in homes. However, energy codes need to advance by incorpo-rating such practices, not by mandating new tech-nologies and techniques. In the spring of 2009, BCAP conducted a builder survey to collect data on what is common practice and uncover opportunities to “catch up” the code to energy-efficient technology and methods that have been proven in the field but are not in the code.
