Variable refrigerant flow (VRF) HVAC zoning and geothermal systems are two of the most energy-efficient options for heating and cooling available—now, new hybrid assemblies combine the two. This article provides an overview of geothermal (or water-source) with VRF zoning technology and its advantages compared to traditional geothermal systems, air-source VRF zoning systems and conventional HVAC systems. In addition, the article will discuss considerations for specifying water-source VRF zoning systems and provide case studies of successful applications.

The Oak Ridge National Laboratory (ORNL) recently undertook a series of trials comparing the moisture and temperature management properties of several different exterior insulation and finishing system (EIFS) configurations with those of other claddings. This article looks at how the research was conducted (along with related modeling software), and focuses on the findings for different types of climate locations, and other data.

This article explores some of the benefits realized through the speed of construction enabled by specifying insulating concrete forms (ICFs)—a technology that combines reinforced concrete with thermal insulation. The piece profiles diverse projects—a school, a multi-family midrise, a big box, and a hotel—in detailing the cost efficiencies. It also looks at ICF design possibilities, installation techniques, and accessory products.

In the October 2014 issue of The Construction Specifier, an article examined how urban lumber harvesting has emerged as an option for resources otherwise devastated by the emerald ash borer. It takes a particular look at how Milwaukee, Wisconsin, is becoming an important player in finding new opportunities for wood—carpentry, casework, and flooring included. This web piece takes the story further.
