Abstract
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.Keywords: Energy efficiency, energy building, energy saving, library building, energy simulation Pemanfaatan energy fosil dalam jumlah yang besar secara global menimbulkan permasalahan berkaitan dengan lingkungan. Usaha untuk mengimplementasikan teknologi dalam penghematan energi sangat signifikan dalam penerapannya pada bangunan. Tulisan ini mendiskusikan parameter-parameter penghematan energi serta mensimulasikannya pada sebuah bangunan perpustakaan Universitas Surabaya yang terdiri dari 6 lantai. Simulasi dilakukan menggunakan sofware EDGE. Hasil simulasi menunjukkan bahwa kombinasi 4 parameter penghematan energi dapat memberikan penghematan energi hingga 53%. Parameter tersebut adalah daylight photoelectric sensors for internal spaces (OFE29), radiant cooling and heating system (OFE16), higher thermal performance glass (OFE8), dan external shading devices (OFE4). Implementasi keempat parameter tersebut akan mengurangi emisi karbodiokasida 758 ton per tahun dengan payback period sekitar 2,2 tahun.Kata kunci: Efisiensi energi, energi pada bangunan, hemat energi, bangunan perpustakaan, simulasi energi
