Energy Efficiency
Energy efficiency is a key objective for LSI’s operations. LSI has established a cross-functional Energy Conservation Team committed to improving LSI's energy efficiency, reducing cost and associated green house gas emissions. The team places an emphasis on Whole Building Analysis techniques followed with implementation and life cycle cost and emissions analyses to determine which projects to promote. Energy conservation methods, projects, and programs include:
- Modernized and decommissioned Data Center servers and other IT equipment with an increased emphasis on energy use reduction
- Intense analysis of Data Center temperature and relative humidity requirements and the energy streams to deliver the required spectrum of requirements without wasting energy
- Installation and use of higher efficacy (i.e., fewer watts per lumen) lighting systems which includes use of motion sensors and timers
- Re-lamping in cases where higher efficacy lighting systems require fewer fixtures per square foot
- Purchase and use of USEPA Energy Star labeled office equipment including effective use power management settings
- Replacement of old control systems with modern digital Building Automation Systems
- An increased focus on Recommissioning and scrutiny of the settings of automated controls and building energy management systems to optimize central heating, ventilating, and air conditioning (HVAC) performance
- Identifying and replacing oversized air compressors and other process systems and equipment that could not be operated efficiently because they were mismatched to newer lower loads
- Extensive use and new installations of variable frequency drives
- Extensive replacement and installation of air-side economizers to automatically control dampers to cool with outside air
- Improvement to existing water-side economizers to extend the Winter operating hours so our large chiller compressor motors draw power fewer hours than ever
In 2010, LSI ‘s Milpitas McCarthy Blvd campus has been certified as an USEPA Energy Star labeled building and our Munich Metris campus is registered and meets the gold certification level under the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED). Rated features include water and energy efficiency, quality of materials, indoor environmental quality and sustainability. Additionally, LSI has voluntarily entered into agreements with local utilities to curtail energy usage during critical high peak demand periods to prevent community brown-outs and black-outs. LSI also encourages ride sharing through our carpool database, telecommuting and teleconferencing to reduce green house gas emissions associated with travel.
