Report outlining workflow and results of regression models on monthly and daily utility data (meter readings of electricity consumption), outlining a process for screening and gathering useful results from inverse models.

Information sheet about reservoir claddings.

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

Report exploring alternative methods to find long-term solutions to energy loss in 1 ½-story homes to save energy, improve comfort, prevent frost buildup on the underside of the roof deck, and reduce the risk of ice dam formation/reformation.

Research study evaluating energy savings and cost effectiveness of installing low-emissivity (low-e) storm windows over existing windows in residential homes in all climate zones.

Report outlining the issues with using existing ducts with a new low-load HVAC system, which reduces throw at supply registers causing decreased mixing of supply and room air, leading to potential thermal comfort complaints.

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...

In this report, BSC seeks to research and report on the field monitoring of the performance of in-situ supplemental dehumidification systems in low-energy, high performance, homes in a hot-humid climate.

Report describing research that helps inform best practices for air-sealing multifamily buildings in the Northeast.

Research report presenting results of short term tests on measures used in an energy efficiency retrofit project in California.

Report summarizing the status of a central hydronic heating system project in multifamily housing at the conclusion of the 20112012 heating season.

The study described in this white paper is based on building energy modeling with an important focus on the indoor humidity impacts of ventilation.

Measure Guideline describing how to assess and carry out the isolation of natural draft combustion appliances from the conditioned spaces of low-rise residential buildings.

This measure guideline provides guidance on combustion safety inspection procedures for appliances and heating equipment that use indoor air for combustion and dilution of flue gases in low-rise residential buildings.

Report providing step-by-step instructions for heating contractors and hydronic designers for selecting the proper control settings to maximize system performance and improve response time when using a thermostat setback.

Case study about how to properly tape insulating sheathing drainage planes.

Guideline describing information and specifications relevant to air-seal existing attics.

This document addresses adding—or improving—mechanical ventilation systems to existing homes. The purpose of ventilation is to remove contaminants from homes either directly or by dilution. This report discusses where, when, and how much ventilation is appropriate in a home, including some...

This report investigates whether mini-split heat pumps can live up to their potential for one market segment: multifamily retrofits.
