摘要

This paper presents the evaluation and optimization results of the office building Siedlungswerk as part of the EVA project. Within EVA, 19 German office buildings are being "eva"-luated in terms of energy efficiency and user comfort. Built in the early 1990s in the city center of Stuttgart the building Siedlungswerk provides office spaces for 135 employees on a net heated floor area without a parking garage (NGF_r) of 5.589 m~2. The evaluation showed an annual consumption of primary energy of 614 kWh/(m~2_(NGFr)a). This was the highest within the EVA sample and significantly above reference values. Users complained about high temperatures in summer and low temperatures in winter especially during the morning hours. A short term monitoring of the indoor climate confirmed these problems. A comprehensive concept of improvement was implemented at the end of 2004 at a total cost of 250 T€ including 100 T€ for improvements in energy efficiency. The following year showed a reduction of 36 % in consumption of electrical energy and 49% in gas consumption. The energy savings generate annual cost savings of 50 T€, which equals a return on invest in energy efficiency after two years. The optimized building operation also significantly improved the user comfort.
