| Abstract | Globally, the energy performance of the buildings is measured in final energy per floor area has increased by 1.5% per annum since 1990. Energy use in buildings is predicted to escalate in future because of increasing population, economic growth and climate change. Educational institutions which consists of building has a potential for energy reduction of 30%. The RETScreen software is used to study the electricity consumption pattern at institute level (Asian Institute of Technology) and to identify the energy efficiency measures for improving energy efficiency at a building (library). Typical energy efficient options in buildings are discussed along with efficiency trends in common appliances which have major share in electricity consumption. Results of the previous case studies done on energy assessment in buildings and AIT were reviewed and the software’s used to assess energy use in buildings were compared. Input data required for the performance and feasibility module using RETScreen was studied and data related to inputs required was collected by noting the procedure to collect them. Then the performance at institute level and building level was assessed using the factors identified by RETScreen software. The overall electricity consumption during past 5 years from 2013 to 2018 was used to study the energy consumption of AIT. The specific electricity consumption rate of AIT was estimated to be 0.5 kWh/m2 which may be high when compared to other universities because AIT electricity consumption includes consumption of AIT conference centre, residential space (students, staff, & faculty) and other academic buildings. It was found that factors such as weather, occupancy did not much influence the electricity consumption. In case of library, the electricity consumption of the library varies from 1000 to 1200 kWh/day and on a holiday, it consumes about 50 kWh/day. On average, the electricity production on roof top of library building is about 200 kWh/day. It was found that both occupancy and CDD has no influence on electricity consumption of library. Feasibility analysis for library building was done using feasibility module in RETScreen software to know the financial viability, environmental impact of implementing energy efficiency measure. It is found that 15,404 kWh/year of savings can be obtaining by energy conservation measure before implementing energy efficiency measure at library building. The possible annual energy savings that can be obtained by replacing Fluorescent T8 with LED in library building is 90,727 kWh/ year which is 25% reduction actual electricity consumption. The possible annual energy savings that can be obtained by replacing CFL with LED is 8130 kWh/ year which is 3% reduction from actual electricity consumption of library building. In this case 4.5 tCO2 is reduced every year which is equivalent to 1 acre of forest absorbing carbon. It is recommended that using detailed measurements on occupancy, and to study the performance of chiller and PV production by using performance module in RETScreen which can be used to predict the actual baseline for energy consumption in AIT. A study on portfolio analysis is recommended which helps analysing various facilities in AIT and can help in energy management and energy reduction, and this can consider not only electricity but also other energy forms in the campus. |
