2009 edition of code establishing a baseline for the design and installation of fuel gas systems and gas fired appliances through performance requirements.

Article describing methods for thermally isolating a garage in a Passive House-certified multifamily building.

The Guide addresses walls constructed with 2x4 wood frame studs, wood structural panel sheathing (WSP) as wall bracing and added backing for foam sheathing, a layer of rigid foam sheathing insulation up to 1.5 inches thick over the WSP, and a cladding system installed over the foam sheathing in low...

Part I of the Guide addresses walls constructed with 2x6 wood frame studs, wood structural panel (WSP) sheathing as exterior sheathing, gypsum board as interior sheathing, and a cladding system installed over WSP sheathing in low-rise residential buildings up to three stories in height.

The Guide addresses walls constructed with 2x4 wood frame studs, wood structural panel (WSP) sheathing as wall bracing and added backing for foam sheathing, a layer of rigid foam sheathing insulation up to 1.5 in. thick over the WSP, and a cladding system installed over the foam sheathing in low...

Report covering the fire performance of combustible cladding over combustible insulation.

Article describing issues with condensation in unvented attics insulated with open-cell spray foam.

Report describing the objective evaluation of space conditioning interactions between heat pump water heaters and home heating systems during winter 2016-2017, revealing a smaller than anticipated impact on space conditioning loads.

Web resource that lays out the pre-work considerations, methods and finishes for installing mechanical insulation.

Study in which a central heat pump water heater system was monitored in detail and used to create a model for assessing similar systems in various climates.

This project analyzed combined condensing water heaters or boilers and hydronic air coils to provide high efficiency domestic hot water (DHW) and forced air space heating. Called "combi" systems, they provided similar space and water heating performance less expensively than installing two...

Factsheet describing the use of rigid foam insulation to meet energy efficiency requirements and minimize fire risks.

Conference paper describing testing of the performance of fasteners used to attach rigid foam insulation to the exterior of walls.

Article describing the evolution of the IRC to permit class 3 vapor retarders (latex paint) in walls coupled with exterior continuous insulation to allow drying and reduce condensation risk.

Report covering the migration of wind-blown embers in roof vents.
