Energy-efficient Design with Masonry Construction

Masonry materials and wall systems, with their inherent thermal mass characteristics, provide designers with many options to achieve energy-efficient designs. This article illustrates examples of wall configurations that exceed national building code requirements and high-performance standards, taking into account factors like increased R-values for non-mass opaque walls (prescriptive design), continuous insulation, requirements for R-value reductions caused by thermal bridging, mandatory continuous air barriers, and options for building energy design.

Energy Efficiency and Building with Wood: Six Building Lifecycle Steps

Buildings have an impact on people and the environment throughout their entire lifecycle, starting with extracting resources from the earth to putting them back in the earth, or burning them, at the end of their lives. To evaluate the effect of buildings in this regard, everything from the energy they consume, the waste they generate, and the carbon dioxide (CO?) they emit must be considered throughout six major cycles.

Energy Efficiency and Building with Wood

The combination of wood and energy efficiency in construction can be the result of new wood technologies. Introducing new sustainable forestry management policies and manufacturing with engineered lumber products will lead to alternative building practices using glued-laminated (glulam) and cross-laminated timber (CLT), computer-aided manufacturing, and optimal value-engineered framing. The lifecycle of a building, energy measurement, and Passive House design elements are discussed.

Building automation systems (BAS) have evolved rapidly over the past several decades, expanding beyond HVAC alone to monitoring and controlling numerous other building systems. This article explores the opportunities from implementing BAS in new construction and in building retrofits, the latest features and benefits available, and factors to consider when specifying BAS controllers, software, and wall sensors for commercial and institutional buildings.

Reducing Environmental Impact with Coatings

Untitled-1

Inadequate insulation and air leakage are leading causes of energy waste in most projects, and coatings selection can play a big role in reducing these inefficiencies. This article examines use of coatings in applications as diverse as cool roofs, air barriers, infrared (IR) reflective pigments, and radiant heat barriers.
