Document providing guideance and considerations for duct design in an energy efficient house.

Report on the stability of furring strips as a means for cladding attachment over walls with thick exterior rigid insulation.

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.

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...

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.

Job Process sheet for the manufactured housing industry showing how to cut insulation batts to fit wall cavities in a factory production environment.

Guidance document on deep energy retrofits.

Report identifying two barriers that limit the ability of builders to explore opportunities for higher levels of energy efficiency in housing: the use of duct system materials that inherently achieve airtightness and are right-sized for low-load houses, and, the ability to air seal fire separation...

Report on the field evaluation of whole-building approaches and estimation of the relative contributions of select technologies toward reducing energy use related to space conditioning in new manufactured homes.
