<br/><br/> Due to increase in climate change and urbanization, Net Zero Energy Buildings are one of the most<br/>effective solutions in energy and building sectors. Techniques to decrease the cooling and heating<br/>loads have been applied to buildings for centuries such as vernacular design. The challenge<br/>researchers are facing in the current weather scenario is to retrofit different energy efficiency<br/>measures to decrease energy load. These measures can be passive or active measures. In previous<br/>research, energy refurbishment using more than five energy efficiency measures lacks for sub<br/>tropic humid regions. The use of cork as insulation and heat pumps as energy efficiency measures<br/>has not been performed before for sub tropic humid region. In this research, a building is modeled<br/>with climatic data of Islamabad. It is later calibrated with mean bias error and calibration signature.<br/>After the verification of simulated building, six energy efficiency measures are applied such as<br/>insulation on external wall, insulation on roof, improvement of transparent objects, insulation on<br/>ground floor, change of HVAC system and solar PV panels. First passive measures are applied to<br/>the model and then active measures. Each energy efficiency measure is chosen on the basis of<br/>availability, net present value and discounted payback time. The main concept behind the research<br/>is to decrease the primary energy consumption of the building and excess energy can be exported.<br/>After the implementation of EEM, it was observed that parameter with high effect on primary<br/>energy consumption is as insulation on external with lowest effect that was of insulation on ground.<br/>Solar panels are modeled in such a way that it provides excess energy for net metering. The<br/>challenge to decrease the primary energy consumption can be solved by these measures. The policy<br/>makers, engineers and architects can benefit from this research to further research on weather like<br/>Islamabad that is sub tropic humid.
