Energy Saving Measures and Simulation in the Library Building of University of Surabaya Tarigan, Elieser

The rapid rate use of fossil fuels globally results in many environmental problems. The adoption of energy efficient technology has the potential to substantially reduce the amount of energy used in buildings. This paper discuses the energy saving measures and simulation for a six-floor library building, University of Surabaya, Indonesia. Simulation was carried out using the Excellence in Design for Greater Efficiency (EDGE) simulation software. The results of simulation showed that 53% of energy efficiency can be reached, without lowering of the building comfort, by applying of four measures at the same time are daylight photoelectric sensors for internal spaces (OFE29), radiant cooling and heating system (OFE16), higher thermal performance glass (OFE8), and external shading devices (OFE4). The implementation of the four measures would result in reduction of 758 ton of CO2/year with a payback period of 2.2 years.

Simulation studies for a PV system would be useful for planning before real implementation, and to predict the cost for a large scale PV system. This work is to simulate a 3 kWp rooftop photovoltaic (PV) system under the climate of Surabaya, Indonesia. SolarGIS PV Planner and RETScreen simulation tools are used in this work. The simulation results are then compared with a full year of measurement results. The results of simulations show that a 3 kWp rooftop system could produce electricity of 4,200 kWh per year, while in the real measurement energy production is found about 3,898 kWh per year. There were slightly different results values of energy output between Simulation and real measurement of the PV system, however statistically it still can be accepted. Economic analysis shows that, under current conditions, a grid-connected PV system investment would give about 5 years of the payback period. Environmentally, the 3 kWp PV system would provide a reduction of CO2 emission of about 2.7 tons per year.
