Energy Efficient Built Environment of the R&D Institute of the Transilvania University of Brasov Romania

Abstract

The built environment newly developed by the Transilvania University of Brasov, Romania into the R&D Institute, the first phase of the Green, ENergy Independent University CampuS (GENIUS), is presented in the paper. The state of the art materials and solutions implemented in the design process of the buildings are described. The Low Energy Building standard is targeted, taking into account the thermal (heating, cooling and domestic hot water) and electrical (lighting) energy consumption of the building. The energy performance of a building is assessed through TRNSYS simulations according to its location (mountain, temperate continental climate area), occupancy and specific office activities, resulting a specific energy consumption of 79 kWh/m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> /year. A renewable energy mix consisting of a 22 kW ground-water heat pump, two flat plate solar thermal collectors and a 12 kWp photovoltaic platform is considered to cover 90.9% of the building energy demand.
