无论是《基本原理手册》还是任何其他单一来源，都没有提供定义住宅建筑围护结构框架因素的统计信息。然而，框架因素是定义住宅结构整体围护结构热性能的主要特征之一。为了使影响全国能源效率水平的重大决策更适合开发更准确、更具成本效益的节能机会，需要进行这项研究。该研究项目的目的是收集低海拔地区轻型框架墙施工特征的统计信息- 增加住宅建设。这些信息将涉及房屋类型、几何结构和施工技术。预计这些统计信息将被组织成有用的格式，纳入《基础知识手册》。主要研究人员:Alex McGowan，Enermodal工程有限公司进行:1999年9月至2001年10月

Neither theHandbook of Fundamentalsnor any other single source presents statistical information on defining framing factors for the residential building envelope. Yet, the framing factor is one of the major characteristics, which define the overall envelope thermal performance in residential structures. This research is needed in order that major decisions affecting the energy efficiency levels throughout the country may be better suited to develop more accurate cost effective energy savings opportunities.The objective of the research project is to collect statistical information on the construction characteristics of light frame walls in low-rise residential construction. The information will refer to house types, geometry, and construction techniques. It is anticipated that this statistical information will then be organized into a useful format for inclusion in theHandbook of Fundamentals.Principal Investigator: Alex McGowan, Enermodal Engineering LimitedConducted: Sept. 1999 - Oct. 2001
