Description

At the beginning of the 2013 winter semester, the Fulda University of Applied Sciences (Hochschule Fulda) moved into a new complex consisting of a university/state library, an attached cafeteria with a main kitchen and an experimental kitchen and a new Student Service Center. In a 2008 architectural design competition, the university, the state of Hesse and the contractor for the project had specified that the project should emphasize sustainable construction methods and that the finished facility’s energy efficiency should be 30% better than that required under the German 2009 Energy Saving Ordinance (EnEV 2009).

Input

Technical building services: Planning and monitoring, sanitary engineering, heating systems, ventilation and air conditioning, cooling systems, electrical engineering, telecommunications, conveying systems, measuring and control technology, building automation.

Unique / Key Features

The project’s architects and engineers collaborated intensively throughout the effort, beginning with the preliminary planning phase. The design team was able to meet the demanding energy efficiency requirements by integrating use of process-related waste heat within the basic designs for the building services. Heat for the combined university open-access library is supplied via a bivalently operating heat pump (air/water). When outside temperatures are especially low, additional heat is provided via the complex’s heating network (gas-fired condensing boiler). The heat pump, a reversible unit, has been integrated within the library’s central ventilation system. When the pump is operating in heating mode, this arrangement enables it to use the heat contained in the ventilation system’s exhaust air. The system is able to “deheat” the exhaust air to a temperature lower than the outside temperature, and its heat production is comparable to that of a conventional air-only heat pump. When the library’s systems are running at full capacity, they can generate more heat than the library itself requires. The excess heat so produced is transported into the SSC and meets about 18 % of that facility’s heat requirements. Water heating is decentralized; it is carried out by electronically controlled continuous-flow water heaters.
