Car Dealerships and LEDs: Implement Sustainability and Reduce Costs

When car dealerships try to outshine each other through the use of bright light on their lots, much of the light spills off the lots’ parameters, and is also wasted upward. While these lights serve a dual purpose of attracting potential customers and as a 24/7 security system, they devour energy. Light-emitting diodes can help.

A Look at Cool Roof Options

Providing roofs with a reflective surface is not a new concept. For example, asphalt coatings with leafing aluminum pigment have always promoted the benefit of reducing interior temperatures while slowing the oxidation of the waterproofing membrane. However, the term ‘cool roofing’ was more recently coined with the increased focus on the reduction of energy consumption. This article examines options from built-up roofs (BURs) to modified-bitumen (mod-bit) systems to single-ply membranes.

New technologies can provide optimal natatorium environmental control and energy savings. Today’s indoor pool dehumidifiers and outside air ventilation systems technology has changed so much over the last decade, a new or retrofitted natatorium stands to save millions of dollars in energy costs over the 15 to 25-year lifecycle of the equipment. Equipment comes with reduced refrigerant charges of up to 85-percent, compressor heat recovery for free pool water heating, exhaust heat recovery for preheating outdoor air, modulating controls for pinpoint temperature and humidity control, glycol heat rejection to dry coolers, and web-based microprocessor monitor, alarms, and control for factory technician review.

Seeing the Urban Forests for the Trees: Secondary benefits of our cities’ wood

In the wake of the devastation caused by the emerald ash borer, urban lumber harvesting has emerged as a response in the United States and Canada. Instead of grinding the wood into mulch, the urban wood movement promotes using urban forests to provide distinctive finishes for built spaces while also connecting those spaces to a piece of history. Designers, contractors, specifiers, and related professionals wishing to use urban wood must be aware of special considerations if they wish to take advantage of this unique resource.

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 (CO₂) they emit must be considered throughout six major cycles.

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.
