High-efficiency ventilation and heating systems by means of solar air collectors for industry building refurbishment

Abstract

For the purpose of energy conservation, modern buildings are becoming more and more air-tight and generally rely on a mechanical ventilation system. According to the literature, solar air heating systems can contribute in a cost-effective way to the heating and ventilation of utility buildings. Especially cost-efficient, unglazed, facade-integrated solar air collectors seem to be an attractive new market for facade renovation. To demonstrate the technical feasibility of generating heating energy on facades, a demonstration plant based on an unglazed solar air collector was installed in 2013 in the facade of a demonstration building and was intensively studied using energy metering.
