Energy efficient improvement of an office building model   Fraga De Cal B.   2017/04/25

Abstract

Building Information Model (BIM) is designed to analyse and improve the energy efficiency of a
existing building of offices in Madrid, Spain. Three models are compared in order to reduce energy consumption and meet the current European legal framework. Firstly, lighting and insulation are considered to improve at least 10% the energy efficiency of the building. Then, a reversible Heat
Pump is fed by photovoltaic panels working along with a Heat Recovery Ventilation System. Furthermore, a biomass boiler is implemented to provide underfloor heating substitute former fan coils. The aim is to meet in excess 40% of energy demand with a renewable source.It is concluded a reduction of 11.14% in the energy demand by adding an air cavity wall, roof insulation, Argon gas gap in windows and low consumption lighting. Furthermore, the addition of the biomass boiler along with the underfloor heating resulted in a he heat load reduction of 33.07%
