– Install motion sensors for security lighting. Sensors can activate security lightingonly as necessary, eliminating the energy waste of round-the-clock lighting.– Use two different circuits for temporary lighting, one for OSHA-required work lightingand the other for temporary emergency lighting kept on at night for security purposes.– Wire temporary lighting with the conduit systems installed for the project. Note thatthe use of new conduit systems is often not allowed for temporary construction lighting,requiring the installation of temporary distribution wiring that is later discarded.– Use energy-efficient lamps and equipment for temporary lighting. Most temporarylighting on construction projects is incandescent. Consider the use of compact fluorescentlamps, which offers paybacks in reduced consumption (although compactfluorescent lamps are more expensive than their incandescent peers, they use considerablyless energy to produce the same quantity of light) and reduced maintenance(compact fluorescent lamps last significantly longer than incandescent lamps,reducing the time and cost associated with lamp replacement and maintenance).Bear in mind, however, that cost-effectiveness varies, depending on such factors ashours of operation, utility consumption rates, replacement costs, and material costs.– Install low-flow fixtures and appliances for reduced water use during construction.Install a temporary drip watering method for exterior landscaping. Consider rainwaterfor irrigation (see Chapter 7, “Site Materials and Equipment”).– Reuse captured stormwater and/or construction wastewater on the project site.Settling ponds, for example, can be used during construction, then made into permanentsite features.– Use the building’s new or existing HVAC system to provide temporary ventilationor conditioning (heating and/or cooling). Coordinate this use with good IAQ practicesso that systems are properly maintained and cleaned. Note that the use of newor existing HVAC systems to provide temporary ventilation for construction is oftennot permitted (see Chapter 13, “Indoor Air Quality”).❑ Use products and materials with recycled content, as appropriate and consistentwith construction plans and specifications, good IAQ practices, and health recommendations.The use of building materials with significant recycled content helps divert recyclablesfrom disposal at the landfill. It also reduces the use of raw materials and, in turn, thedepletion of natural resources.❑ Use products and materials with reduced packaging and/or encourage manufacturersto reuse or recycle their original packaging materials.Such strategies help divert materials from disposal at the landfill and reduce the use ofraw materials. The associated reduction in waste and disposal cost can also result insavings to the contractor and developer.❑ Purchase materials in a manner that minimizes waste and unnecessary costs.For example, purchase nine-foot sheets of drywall if the ceiling height in a building isjust under or exactly nine feet.❑ Require an on-site recycling system for waste materials (for resale, in the case ofmetals, or for giveaway to local programs or at curbside).Recycling waste materials on-site requires the development of a plan to accumulate,separate, and store the materials until they can be transported to an appropriate market.As part of the plan, identify markets for recyclable materials to determine the economicfeasibility of construction waste recycling. Markets for recycled buildingmaterials vary throughout the country; typically, however, markets for recycled steeland other metals, masonry, concrete, untreated dimensional lumber, corrugated cardboard,and asphalt exist. In all cases, on-site separation and stringent monitoring ofrecyclable materials are critical. Contact the local waste management board for morerecycling information. (See Chapter 1, “The Economics of Green Buildings,” for a construction-wastesavings example.)❑ Require the recycling and reuse of materials salvaged from demolition.Building materials salvaged from demolition may be used as building fill material or
