Energy-efficiency requirements were developed for manufactured homes, which are regulated by the U.S. Department of Housing and Urban Development (HUD). A life-cycle cost analysis from the homeowner's perspective was used to establish parameters for a least-cost home in a large number of cities. Economic, financial, and energy-efficiency measures for the life-cycle cost analysis were selected and documented. The resulting energy-efficiency levels were aggregated to zones that were expressed as a maximum overall home U-value (U0) requirement for the building envelope. The proposed revised standard's costs, benefits, and net value to the consumer were quantified.  This analysis updates a similar effort completed in 1992, which was the basis for the existing HUD code U0 requirement.  Updated U0s for manufactured homes are recommended.

The sun is the main source of heat in all homes. By looking at how houses receive sunlight, site planners can help optimize how much solar energy is available to heat a house, and how much heat must be removed with air conditioning. In hot climates, site planners should use lot orientation to avoid solar gains in the summer.

The appropriate treatment of task lighting for energy code compliance has always been a potentially confusing issue. The intent of ASHRAE Standard 90.1-2007 (as well as previous editions back to 1999) and the International Energy Conservation Code (IECC) (including editions back to 2003) is for task lighting to be included in compliance calculations when it is part of the lighting design. This applies to office spaces where task lighting is common, as well as other spaces where task lighting may appear in various forms.

This technical support document (TSD) is designed to explain the technical basis for the COMcheck software as originally developed based on the ANSI/ASHRAE/IES Standard 90.1-1989 (Standard 90.1-1989). Documentation for other national model codes and standards and specific state energy codes supported in COMcheck has been added to this report as appendices. These appendices are intended to provide technical documentation for features specific to the supported codes and for any changes made for state-specific codes that differ from the standard features that support compliance with the national model codes and standards. Beginning with COMcheck version 3.8.0, support for 90.1-1989, 90.1-1999, and the 1998 IECC and version 3.9.0 support for 2000 and 2001 IECC are no longer included, but those sections remain in this document for reference purposes.

The purpose of this brief is to provide a discussion related to amending or not amending model codes and standards when adopting them at the federal, state, or local level. It was considered necessary based on the significant amendment activity related to energy code adoption and the observation that in almost every case mistakes are made—some as significant as inadvertently excluding key building types from the code. In some cases, governing bodies will opt to amend with the goal of increasing energy savings; this is positive, and it is necessary to have states that are trendsetters with regard to efficiency. However, it is sometimes possible for amendment activities to yield the opposite result because of increased debate about the technical provisions and the “islanding” of jurisdictions with respect to the support infrastructure available for implementation and compliance with the model codes and standards.

The intent of the vestibule requirement is to reduce infiltration of air into a space, thereby addressing energy conservation and comfort issues for occupants located near primary entrance doors. The majority of infiltration comes through primary entrance doors that are typically used to access public areas, and have higher usage rates than doors classified for personnel use. Vestibules can reduce the infiltration losses (or gains) from wind and stack effects by creating an air lock entry.
