| Resource Title | Building envelope optimization using energy modelling for energy efficient design of a case study public elementary school building |
| Date Issued | July 2021 |
| Abstract | The building sector holds a significant share in total final energy consumption globally and in the Philippines. In the Philippines, consumption is continuously increasing due to increased electrification, improved living standards, and increasing ambient temperatures. Space cooling will be among the fastest growing end uses. With this, it is important to have a good understanding of how design and material choices could impact indoor conditions and thus impact energy use, particularly for cooling. This study investigated the indoor thermal conditions and overheating risk in a case study public elementary school building. Building energy modelling was used to generate simulations and evaluate current design and alternative envelope design strategies. It was found that overheating occurs in the current building design for 72% of the total occupied schooldays. Alternative design simulations showed that building envelope design strategies can significantly improve indoor thermal conditions and can provide energy savings. Optimum envelope design of high thermal mass walls, insulated and high reflectivity roofing, and low U-Value and low SHGC windows have the potential to decrease overheating risk by up to 53%, but could not provide total elimination of overheating risk. Using air conditioning for total overheating risk elimination in the base case design would correspond to 159,356.36kWh annual schoolyear consumption. This can be reduced by 42.81% with the application of the optimum building envelope design strategy. |
