The Builder's Guide provides the building industry with the latest and best practical information on how to apply building science principles to structures as systems in hot-humid climate regions.

Research study investigating the energy performance and cost effectiveness of several state-of-the-art retrofit strategies that could be used in residential houses in the Boston and New England area.

The objective of this research was to quantify the field performance of wood-frame walls clad with a variety of common claddings in a mixed-humid climate.

Report focusing on building envelopes that have been enhanced with phase change materials (PCMs), which can simultaneously reduce total cooling loads and shift peak-hour loads.

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. Walls with...

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...

Article Describing methods for thermally isolating multifamily parking garages.

Guidebook providing useful examples of high performance retrofit techniques for the building enclosure of wood frame residential construction in a cold and somewhat wet climate.

Guidance document on deep energy retrofits.

Information sheet with details on a building enclosure designed for Albuquerque, NM, as an example for building enclosures built for hot-dry and mixed-dry climates.

The next generation of building enclosures is a key step toward achieving high-performance goals through decreasing energy load demand and enabling advanced space-conditioning systems. Yet the adoption of high-R enclosures and particularly high-R walls has been a slow-growing trend because...

Report focusing on the performance and durability of unvented-cathedralized attics in hot-humid climates with both tile and asphalt shingle roofing.

Research project aimed to verify whether homes in the New Jersey HPwES program achieved 30% source energy savings, and if so, what measures were implemented to achieve them.
