Kurzfassung englisch:
Existing industrial buildings implement retrofit measures to reduce energy demand for space conditioning, with primary focus given to heating loads, as existing industrial halls often lack cooling systems. However an optimized refurbishment should be able to tackle summer overheating, since studies indicate an increase in the frequency of hot days and intensity of heat waves. In addition, fluctuations of production and economic cycles have an impact on manufacturing process loads and thus internal heat gains affecting building performance. If production levels alter in the long term, an initially satisfying option may fail to respond to the future conditions. This paper presents stepwise retrofit alternatives based on varying manufacturing process load levels for a case study of a historical industrial facility in Austria. A thorough picture of the initial condition was achieved by measurements of indoor climate conditions and energy consumption. Based on a calibrated dynamic thermal simulation model, optimization measures and natural ventilation patterns were tested under current production conditions and hypothetical future scenarios for their adequacy of minimizing overheating. Results were classified and evaluated by adaptive comfort and workplace regulation criteria, while differences between the two approaches were discussed. There are measure constellations diminishing overheating for all internal heat gain conditions, whose applicability can adapt to the prevailing needs of the facility at the time, hence providing a more cost-effective initial investment.
