Sandia National Laboratories Building 753
The Department of Energy Sandia National Laboratory's Building 753 in Albuquerque, New Mexico, is a one-story office building that was strategically selected for the installation of occupancy sensors for lighting and HVAC automation for two reasons: It was already fully metered, and it was relatively small.
The energy reduction at Building 753 was designed to leverage the existing building metered system and take occupancy sensing to a higher level. Improvements included:
- Installing new occupancy sensors and connecting them to the office lighting, as well as the building automation system, which controls the HVAC system.
With this "smart" building approach in place, the system senses when the building occupants vacate their offices and will switch lights off. The system also closes airflow dampers in unoccupied offices through the HVAC occupancy sensing meters. The team also worked with the building occupants to allow another addition, which provided the energy saving ability to adjust the thermostats that control the temperature in their offices, allowing occupants to control temperatures according to their comfort during occupancy.
As a result of these improvements, Building 753 is currently a candidate for High-Performance Sustainable Building Guiding Principles for Existing Buildings through its achievement of ENERGY STAR® certification.
