Retrofitting of a School with an Integral Aspect

International studies, like the PISA study [PISA 2006], detect the performance of pupils. Besides the teaching method, other influences are also relevant for their performance. The environment in the classrooms is supposed to play an important role. Caused by sinking numbers of pupils, new school buildings are very rare, and available school buildings will be increasingly retrofitted. A great reduction potential and a not insignificant environmental protection could be achieved by specific measures in this field. But what are the adequate measures? Yet school buildings are different from residential buildings. Therefore, airtight and well insulated building envelopes are not sufficient, because this one-sided approach forces a false user behaviour and counterproductive as concerns targeted energy savings and environmental protection. During the school year 2006/2007 environment measurements (energy consumption, IAQ, acoustics, etc) were carried out in a school in the Munich region and an integral retrofitting strategy was developed. For the first time all relevant factors, not only energy saving, were taken into account. A special focus was laid on the future performance of the pupils.
