Abstract: An energy modelling on Solaris was carried out by Aurecon Singapore as part of the requirements to qualify for the Green Mark Platinum rating. However, the inputs for energy modelling simulations are based on assumptions. As such, this dissertation looks into the validity and accuracy of Solaris’s energy modelling by comparing simulation data (Proposed Model) with Solaris’s actual energy consumption for the year 2013/14. The objectives of this dissertation seeks to uncover any disparities between the actual energy consumption and proposed model results. Further investigation would be conducted to uncover reasons for the disparities. Solutions would then be recommended to address these disparities. A detailed case study was first carried out to allow the author to understand Solaris’s operations and effectiveness of its ‘green’ features. An interview with Solaris’s Facilities Manager and a site visit was conducted as part of the case study. A thorough analysis of the energy data retrieved from the Building Management System will be analysed. Additionally, a post occupancy survey that was conducted by Solaris’s building management team will be analysed and used to understand the energy data trends. In the course of examining the actual energy consumption and proposed model data, it was discovered that Solaris consumed more energy for certain components. Further investigation uncovered that it was because the energy modelling did not take into account of the additional Gross Floor Area that was awarded to Solaris. Hence, to ensure a fair comparison, the Energy Efficiency Index (EEI) was calculated for both data sets. Solaris have managed to achieve an EEI of 149.83 kWh/m2/year which is 2.3% more efficient than the proposed model. This dissertation analysed the data trend over a course of one year and maybe insufficient to draw an accurate conclusion. In conclusion of the dissertation, recommendations were suggested to correct the findings from the occupants’ survey and lower the energy consumption for Solaris subsequently. An evaluation of the recommendations was also carried out to assert the suitability, reliability, flexibility and the economical aspect.
