The Government the Republic of Korea is showing a lot of interest in net zero-energy buildings (NZEBs) to reduce energy consumption of buildings and to promote green growth policy in construction sector. The application of building passive technologies and renewable energies is essential to achieving NZEBs. Green remodeling reinforced the insulation of the exterior walls and roofs of the buildings and replaced high-efficiency windows and doors. In this study, the energy performance before and after green remodeling applied in a senior citizens’ center was comparatively analyzed for baseline case and three different cases, Case-A, Case-B and Case-C. A building modeling software (DesignBuilder V7.0) with EnergyPlus (V9.4) calculation engine was used to evaluate the energy demand and energy consumption of each case. Based on the simulation results of the building’s energy demand for baseline, it was determined that the target building
required more heating energy than cooling energy. The simulation results also showed that the implementation of building envelope performance improvement technologies (Case-A) could notably decrease the heating energy consumption of the building. After the remodeling (Case-A), the source energy consumption per unit floor area was assessed to be reduced by 61.8%, compared to prior remodeling of 363.9 kWh/m²-y. Meanwhile, Case-B can achieve energy savings of 59.4% and Case-C can achieve savings of 63.2%. Following completion of the remodeling project, actual construction costs, and on-site measurements and verification results will be gathered and compared with the simulation results. Additionally, economic analysis including construction costs and payback period will be conducted using actual site data.
