Building Science is the study of buildings and construction techniques as they apply to the performance and sustainability of the structure. Many of the products and techniques associated with green construction are considered good building science.
The housing construction industry ranks among the worst in research and development. The independent nature of small builders combined with market pressures, have previously put the science of building at a low priority level. Rising energy costs and interest in green construction, have fueled the interest to learn a little more.
Additionally, it's apparent that many consumers are demanding higher quality and performance from their builders. Recognized performance standards and third-party inspections are becoming the norm rather than the exception. Assurance that the structure and its systems are sustainable and performing correctly, has only been recently offered within the industry. Prior to recent awareness, there was no means for the consumer to really know what they were purchasing.
