CESBA Principles and Indicators

Quality of site

Since the building is located in the center of town,the pedestrial accessibility of basic infrastructure facilities is very good. It is situated less than 300 metres from the train station, but it has no bus connection. The site itself has been the site of the old town hall of Lorüns that could not be renovated anymore, so there is no additional land consumption which is a very positive aspect..

Process and planning quality

The used building materials both in the interior and outdoor space show the high process and planning quality. The town hall is a timber construction and ecological materials have been used with nearly no exceptions. Regional timber, cellulose insulation and the facade is made out of local silver fir.

Environmental quality

Within the building, the local heating supply of the adjacent fire station is used; warm water is decentrally produced with boilers. The electricity supply comes from the photovoltaic installation of the fire station (annual revenue: 7970 KWh).

Social quality

The town hall is barrier-free and has a controlled ventilation system. No measurements of room air or lighting conditions took place.

Economic quality

No profitability assessment were conducted, since considering different alternatives would have lead to a "downscaling" of the building quality.
