Prescription for Energy Savings: Reducing cost and consumption with upgraded cooling tower fans

19297247_l copy

The average hospital uses three times the energy of typical commercial buildings, and U.S. medical facilities spend $8.8 billion annually on energy. Between lighting, medical equipment, HVAC, and plumbing, energy consumption in medical facilities outpaces any other type of building. For large hospital systems, annual costs can reach into the tens of millions of dollars—no small amount in an industry of thin margins.

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.
