xCalibur Group's 40 year old multi-use facility was faced with high energy consumption, reduced thermal comfort and inadequate indoor air quality. xCalibur's mission was to increase the efficiency of its aged facility and bring the indoor environment comfort level in concert with green building principles.
Working through Nativus Energy's 4 step plan, the facility has been upgraded with a Systemair ERV (energy recovery ventilator) controlled by demand ventilation to meet indoor air quality levels as set forth in ASHRAE 62.1- 2007. For heating and cooling, the facility was outfitted with a VRF (variable refrigerant flow) system that utilizes heat recovery for further energy and increased thermal comfort.
xCalibur has begun the retrofit of its lighting systems with LED's to further reduce its energy demand. With a desire to do more, Nativus Energy has developed a thermal and solar PV solution to further assist xCalibur in expanding it sustainable building approach.
