Guide describing Installing blanket fiberglass insulation on the interior walls of a conditioned, unfinished basement as an alternative to best practice solutions.
Table adapted from Table R402.1.1 in the 2009 and 2012 IECC and Table R402.1.2 in the 2015 and 2018 IECC (Table N1102.1 in 2009 IRC, Table 1102.1.1 in 2012 IRC, and Table N1102.1.2 in 2015 and 2018 IRC).
Guide describing materials and methods for incorporating thermal mass into the construction of a home for temperature regulation, energy savings, and resistance to extreme heat and cold.
Guide describing methods for insulating an unvented crawlspace or conditioned basement with rigid foam on the interior side of the walls to provide an insulated space for HVAC equipment.
Information guide describing things to consider in the basement or crawlspace before attempting retrofits of adjacent items including HVAC, wiring, or structural systems.
Guide describing how to upgrade a wall with a floor overhang (or cantilever) on an existing home by adding insulation (rigid insulating sheathing and/or closed-cell spray foam) and air-sealing.
The intent of this brief is to provide code-related information about gas-fired boilers to help ensure that the measure will be accepted as being in compliance with the code. Providing notes for code officials on how to plan reviews and conduct field inspections can help builders or remodelers...
The intent of this brief is to provide code-related information about sealing and insulating crawl space walls in existing residential buildings to help ensure that the measures will be accepted as being in compliance with the code. Providing the same information to all interested parties (e.g., code officials, builders, contractors, designers, etc.) is expected to result in increased compliance and fewer innovations being questioned at the time of plan review and/or field inspection.
An entirely new section in the 2015 IECC/IRC regarding fuel-burning appliances basically requires the appliance to be isolated from the building thermal envelope, located either outside or within a separate room if the fuel-burning appliance is supplied by open combustion air ducts. This brief provides an overview of the requirements and further details of approving the actual "room".
The intent of this brief is to provide additional information to help assure the measure will be deemed in acceptance with the code. Providing notes for codes officials on how to plan review and field inspect can help the builder or remodeler with the proposed designs and provide the jurisdiction...
This brief discusses the provisions in the 2015 International Energy Conservation Code (IECC) and International Residential Code (IRC) related to evaporative cooling.
Guide describing the principal of compartmentalization in multifamily buildings - the separation of dwelling units from each other and from common areas in terms of air flow. Locations where air-sealing is critical to maintain separation of air spaces and air-sealing methods especially for party walls are also described.
The intent of this brief is to provide code-specific information about air sealing and insulating common walls in multi-family buildings to help ensure that the measures will be accepted as being in compliance with the code. Providing the same information to all interested parties (e.g., code officials, builders, designers, etc.) is expected to result in increased compliance and fewer innovations being questioned at the time of plan review and/or field inspection.
The focus of this brief is on boiler efficiency, sizing requirements, controls, combustion air, and pipe insulation for the 2015 version of the IRC/IECC.
Applicable codes and standards regarding heat pump water heaters (HPWHs) that are an energy-efficient alternative to electric resistance water heaters.
The intent of this brief is to provide code-related information about buried ducts in vented attics to help ensure that the measure will be accepted as being in compliance with the code. Providing notes for code officials on how to plan review and conduct field inspections can help provide jurisdictional officials with information for acceptance. Providing the same information to all builders, designers, and others is expected to result in increased compliance and fewer innovations being questioned at the time of plan review and/or field inspection.
