Description

Authority center Husarenstraße in Braunschweig - Energetic refurbishment SFP 2035 Planning service object planning building according to § 33 ff HOAI 2021Performance phase (LPH) 2 to 8; step-by-step commissioning, i.e. initially LS 1 corresponds to LPH 2 to 4The Husarenstraße authority center is located at Husarenstraße 74.

The neighboring high-rise building of the Altewiekring tax office is also part of the property, and the entire property, excluding Frankfurter Haus, was considered in this rough renovation concept.

However, the presence of pollutants cannot be completely ruled out, and the district heating system on the property will be reorganized in advance and the house connections will be renewed. This is already part of the energy refurbishment and a preliminary investigation is currently underway to identify the necessary energy-related measures. Following the VgV procedure, the energy efficiency report with recommendations for action is available and is to be examined with regard to its economic viability. Sustainability and grey energy are also to be taken into account in the evaluation of all measures, all of which are to take place during ongoing operations, and the development of an economical and cost-effective concept and its timely implementation is the primary objective.
