Case study describing solar thermal and photovoltaic systems in new construction.

Report describing the monitored long-term performance of two solar domestic water heating systems in northern climates.

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 exploring feasibility of designing prescriptive retrofit measure packages for typical Chicago region multifamily buildings in order to achieve 25% source energy savings.

Brochure on specifications for solar thermal systems.

Best Practices document providing an introduction to current photovoltaic and solar thermal building practices.

Article discussing indoor water management.

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.

Document with important building science considerations, designed for members of the residential construction and remodeling industries, as well as owners and managers who work in affordable housing.

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 air-sealing.

Information sheet describing how to select a properly sized water heater based on household usage patterns, peak demand, and heater type—whether tankless, solar, or storage-based—to ensure efficiency and adequate hot water supply.
