![]() A summarized flow-chart of the procedure is shown in Figure 1. The goal of the program is to produce high-quality affordable homes that are energy efficient, healthy, and durable. DOE Energy Efficiency and Renewable Energy. Finally, a proper choice of building envelope thermal resistance should be made in. DOE Energy Efficiency and Renewable Energy. A building envelope is the physical separator between the conditioned and unconditioned environment of a building including the resistance to air, water. DOE Energy Efficiency and Renewable Energy. For additional reading see Maine Home Performance Technical Standards and EPA's Do-It-Yourself Guide to Sealing And Insulating with Energy Star (PDF). If any of these areas show signs of air leaks it is necessary to caulk, seal or weather-strip in order to prevent energy loss. In Ontario, the relevant regulations are outlined in ASHRAE 90.1-2013 chapters 1-4. Accordingly, most governmental bodies have outlined a number of regulations and codes governing the design of commercial building envelopes. Every building should also be checked for air leaks near electrical boxes and outlets, plumbing and ceiling fixtures, attic hatches, and other locations where it is possible for air to pass outside. Alterations to the building envelope shall comply with the requirements of Section 5 for insulation, air leakage, and fenestration applicable to those specific. One of the main functions of a building's envelope design is the safety and comfort of the people using the building. There are many other areas in a building that can be the source of energy loss. Moisture Management is headquartered in Indianapolis, Indiana and serves a diverse set of clients across the United States. For new construction there are new Energy Star-rated window technologies that are designed for energy efficiency and the prevention of heat loss. It is also important to consider adding storm doors to entryways to prevent energy loss at this active area in the building. ![]() Or instead of complete window replacement, consider adding another single pane. 2 Diagram showing the solar gain performance of WFG and conventional glass. Another opportunity to improve the building envelope of an existing building, although expensive, is to replace existing windows with more energy efficient double pane windows. 1 Typical layout of Water House building envelope FIG. ![]()
