Abstract

The renewable energy sources are becoming more and more current in the energy supply of buildings, from residential buildings to institutional buildings. The renewable energy sources have proved to be a solution and an important element of the Romanian Energy System. We are starting from the idea of using the renewable sources to passivize a building, and we are relying on existing facilities in the Multidisciplinary Scientific and Technological Research Institute (ICSTM) from Valahia University of Targoviste (UVT) to produce the energy from its own sources. We are also considering the consumption data from previous year as well as the electric link to external power grid. This paper aims to propose new renewable energy units so that ICSTM become energetical independent. Currently, the ICSTM building consumes an amount of energy produced from renewable sources about three times less than that consumed from the external network. In order to determine the number of equipment, specifically CPV (concentrating photovoltaic) panels placed on trackers, it is desirable to create a 40% reserve above the installed power, taking in account the possible future development of the research laboratories.

Highlights

  • An energy-efficient construction is no more than a construction concept that can be reached and applied by anyone. [1]Multidisciplinary Scientific and Technological Research Institute is part of the University of Targoviste (UVT), being built on an area with a ground footprint of 2240 m2 and a total built area of 7250 m2

  • Solution we propose to achieve the autonomy of ICSTM building is: installing ten systems of concentrating photovoltaic panels (CPV) Tracker type with two axes of 12.00 kWp

  • The ICSTM building is partially powered from renewable sources and partially from national network (SEN) of energy

Summary

Introduction

An energy-efficient construction is no more than a construction concept that can be reached and applied by anyone. [1]. Multidisciplinary Scientific and Technological Research Institute is part of the UVT, being built on an area with a ground footprint of 2240 m2 and a total built area of 7250 m2. The internal part of the building is formed by 35 laboratory spaces, 5 technological laboratories, 6 functional annexes, 7 administrative spaces and 4 dissemination spaces, with installations and equipment used for different activities of research. Multidisciplinary Scientific and Technological Research Institute is equipped with more sources which produce renewable energy: photovoltaic platform, wind platform, thermosolar platform. All those sources cover only one part from necessary consumption for ICSTM, the other part is consumed from the National Energy System (SEN) network
