In its commitment to shift to cleaner energy sources and reduce overall energy consumption, the Ateneo de Manila University has taken active steps to shift to inverter technology, stimulating the energy savings for the Grade School Cafeteria, the Grade School Covered Courts, and High School Covered Courts. This was initiated as a way to compare the actual energy cost consumed by the high volume low speed (HVLS) fans in case the areas were to be air-conditioned.
Shifting to HVLS fans resulted in remarkable energy and cost savings. In the GS Cafeteria, the shift resulted in total energy savings of 164,208.57 KW-Hr per year or cost savings of PHP 1,642,085.71 per year; in the GS Covered Court, energy savings amounted to 162,886.29 KW-Hr or PHP 1,628,862.86 of cost savings; lastly, HS Covered Court saved 141,347.14 KW-Hr of energy savings or PHP 1,413,471.43 worth of cost savings.
The Church of Gesu Air Conditioning System Design and Build Project also applied energy conservation technologies to offset energy consumption. Blow split type air conditioning units with EER not lower than 10.5 and energy efficiency features such as variable frequency drive (VFD) and/or variable refrigerant flow (VRF) were used to implement energy conservation objectives while at the same time ensuring comfort cooling to the space, and the desired temperature and humidity.
