English abstract:
Due to the strengthening of regulations and building codes on building energy performance, as well as with the new ISO 50000 series for energy management and efficiency, existent industrial facilities are using thermal refurbishment and renovation as impetus for increasing their overall energy efficiency. This paper presents strategies for thermal refurbishment and extension for a case study of an existing historical industrial facility. First, a building model of the facility was compiled in BIM (Building Information Modelling) software to serve as a knowledge-database. Then, two refurbishment scenarios of the building envelope were developed and thermal simulation using EnergyPlus was implemented to evaluate the potential for improvement. Thereby the impact of interior loads was considered, determined by measurements conducted on factory machines, occupancy and lighting operation patterns. However, data regarding constructions of the existing facility, information on installed HVAC systems as well as appropriate ventilation and infiltration rates standards for such facilities are limited. To overcome these limitations a study of various material databases was carried out, in order to assess data for building envelope composition. Parameters regarding systems and air-change rates were provided, based on literature, allowing a fair comparison between refurbishment scenarios. Simulation results showed that the heating demand of the factory could be reduced up to 53%. Such reduction indicates a significant potential for energy savings. Beyond energy savings, the thermal performance against summer overheating also depicted considerable improvements.
