To refine your search use the buttons below. First select the type of document you would like to view, next check off the climate zone you are building in.
This paper discusses the differences between vented, unvented and conditioned crawl spaces. Best practice construction techniques and assemblies for conditioned crawl spaces are discussed, the results of a field monitoring program are presented, and the code language addressing crawl spaces is explained.
Everything you ever wanted to know about HVAC for homes-thermal comfort, air distribution, nature of and dealing with contaminants, HVAC strategies, and climate-appropriate graphics to boot.
Understanding the significance of the complex flow and pressure distribution problems created by the interaction of the building envelope with the mechanical system and climate can lead to changes in building design, commissioning, operations, maintenance, diagnostics and rehabilitation.
This presentation examines the integrated system concepts of advanced framing, air flow retarder system, thermal envelope system, air distribution system and mechanical systems.
This article briefly repeats some of the information in the other mold articles but also includes information on how to prevent mold in residential structures.
Humidity concerns in the southern humid climates are particularly difficult to resolve. This is because one of the most effective approaches to dealing with humidity in heating climates, ventilation, can cause major humidity problems in the humid south.
This list contains some of the basic characteristics that should be met in all high performance homes. It has been used as our baseline criteria for all of BSC’s Building America projects.
Energy efficient homes are inherently airtight and require ventilation for acceptable indoor air quality. Recognizing this fact, two building code jurisdictions, the federal department of Housing and Urban Development and the State of Washington, require mechanical ventilation for homes.
This presentation examines health related building problems in public housing.
A presentation examining the requirement for roof/attic venting in hot-humid climates.
A presentation discussing zero energy homes, affordable housing and the available technologies to reach zero energy.
When designing a building’s envelope and its interaction with the mechanical system, temperature, humidity, rain and the interior climate often are ignored.
Moisture accumulates when the rate of moisture entry into an assembly exceeds the rate of moisture removal. When moisture accumulation exceeds the ability of the assembly materials to store the moisture without significantly degrading performance or long-term service life, moisture problems result.
The effects of building development on the environment are at the most basic level about durability. Building a house or community is really about the durability of people, the durability of buildings, and the durability of the planet.
Ventilation air change rate, local mean age-or-air, and interzonal ventilation air distribution were measured for two single-family homes and eight ventilation systems.
