Integrated BACnet® control system helps WPPI Energy facility maximize efficiency and obtain LEED® Gold certification
Sun Prairie, WI
WPPI Energy is a regional power company serving 51 customer-owned utilities that provide electricity to more than 195,000 homes and businesses in Wisconsin, Upper Michigan and Iowa. The company had outgrown their Office and Operations Facility in Sun Prairie, WI, and planned to expand the original building. The new facility needed to be comfortable in order to maximize employee productivity. It also required flexible, easy to use digital controls for the heating, ventilation and cooling system in order to operate the facility at greatest efficiency. WPPI Energy hoped to obtain a LEED® (Leadership in Energy and Environmental Design) Gold Certification for the new building, with full points for energy efficiency.
The new WPPI Energy headquarters facility incorporated many elements of sustainable design, including a geothermal heating and cooling system and heat recovery ventilation. Temperature Systems, Inc. (TSI) designed a BACnet® control system of approximately 2,300 points for the heating, ventilation and air conditioning (HVAC) equipment, accessible to WPPI Energy employees through an i-Vu® web-based user interface. In the resulting facility, WPPI Energy employees enjoy a bright, comfortable new workspace, and facilities staff can track and control the super-efficient heating and cooling system from any web-enabled location. WPPI Energy’s efforts were rewarded with a LEED Gold Certification, with full points for energy efficiency. The company doubled the size of the almost completely electric-powered facility while electric usage remained at pre-expansion levels.
