| JM trailers help cut energy consumption in half Construction trailers and lighting account for more than 70% of energy consumption at a building site. By using better insulated trailers, low-energy lights and timers to control heating and lighting, Swedish housing developer JM will be able to cut energy consumption for trailers and lighting in half. The result will involve a savings of about 9,000,000 kWh annually, which is equivalent to the average energy consumption for 500 single-family homes. JM has decided that all construction trailers at JM's new job sites will be fitted with features such as improved insulation, motion-controlled lighting and heat recovery. In addition, only low-energy lighting will be used at the construction site and will be turned down at night. In all, JM expects to cut energy consumption for trailers and lighting in half. In addition to energy savings, switching to a new type of low-energy bulb has resulted in improved lighting and a better working environment. A work group has spent six months working on the action package to improve energy efficiency at the construction sites, but the initiative actually began almost two years ago. Both in-house measurements and a follow-up in an Uppsala University degree project provided early indications that substantial savings could be achieved from the standpoint of both costs and energy. write your comments about the article :: © 2009 Construction News :: home page |
