| Resource Title | Analysis of Retrofits for Energy Efficiency Improvement of the UP College of Fine Arts New Building Atrium |
| Date Issued | 5 July 2024 |
| Abstract | This study assessed retrofits for energy efficiency improvement of the University of the Philippines College of Fine Arts New Building atrium. Using EnergyPlus simulation software, the baseline annual energy consumption of the atrium was 39,022.06 kWh. The effects of wall, window, and roof insulation retrofits on energy consumption were evaluated. Wall insulations included polystyrene, fiberglass, gypsum board, aerogel-based coating, polystyrene-gypsum board, and fiberglass-gypsum board. Except for gypsum board and aerogel-based coating, all wall insulations in the atrium resulted in reduced energy consumption. This reduction is primarily due to decreased cooling loads, directly reducing air conditioning unit (ACU) usage. Since ACUs are the main energy consumers in the atrium, this decrease leads to overall energy savings. Reduced cooling loads are attributed to significantly lower heat gain or OTTV through the walls. External heat gain through the building envelope constitutes a substantial part of the atrium's heat load. By minimizing external heat gain, less energy is needed to cool the atrium, thereby reducing the ACU consumption and overall energy consumption. Window insulations evaluated were single clear exterior film, single reflective tinted exterior film, single clear interior film, single reflective tinted interior film, double clear film, and double reflective tinted film. All window insulations resulted in an insignificant reduction in energy consumption due to minimal decreases in cooling loads. The negligible reduction in cooling load can be attributed to negligible OTTV reduction through the windows. Consequently, this leads to negligible decrease in energy consumption and energy savings. Roof insulations assessed are polystyrene, fiberboard sheathing, gypsum board, polyurethane foam, roof membrane paint, and opaque glass. All roof retrofits resulted in negligible energy consumption reduction. It is due to insignificant decrease in cooling load which |
