Building Simulation, Solar Potential and Consumption Analysis of Residential Dwellings, in Dubai
City sustainability analysis is overly broad, and people with diverse mindsets look at cities from different perspectives. As part of the city’s fabric, buildings are an integral component and hence require attention. Although the electricity consumed in buildings varies from country to country, it is equal to 30–40% of the total electricity consumption all over the world. . This research targeted studying residential building simulation in Dubai, using various Green Building Codes, assessing energy consumption trends, designing solar systems with respective sizing along with conducting detailed load profile analysis and developing statistical model to directly estimate the HVAC consumption. The results showed that Green Building Codes progression and enhancements have reduced energy consumption gradually, totaling a 37.87% drop at Al Sa’fat Platinum compared to a base case. The EUI for Al Sa’fat Platinum residential villa is 151 KW/m2 and is approximately 60% above the nZEB targets for UAE. Optimum solar PV tilt angles are 25O, south facing, and Al Sa’fat Platinum 10% on-site solar energy mandate results in a payback period of 5 years and compensates 16% of grid import costs. Furthermore, the load profile analysis studied the average day load profiles and changes in load shape for various codes and statistical modeling of villa consumption showed that the about 33% of the Weather Independent Consumption contributed to HVAC consumption share.
