Abstract
Within the Cool-down Güssing project, measures for sustainable cooling of existing buildings were investigated. While in new buildings the heat input can be reduced by intelligent construction and passive cooling measures can be integrated relatively easily by installing surface cooling system (e.g. concrete core activation), the situation in existing buildings is much more difficult. Nevertheless, with suitable measures, sustainable cooling, or at least a significant reduction of the residual cooling demand, can be achieved. It has been shown that there is no universal solution for all different types of existing buildings. For example, different measures are suitable for large production halls of companies compared to private households. Therefore, the buildings were divided into several categories, like private households, companies and public buildings. Different types of night ventilation have shown good potential for public building and companies to reduce room temperatures by at least a few degrees. This can be done either by means of decentralized ventilation units or automatic window openers, or by intelligent control of existing infrastructure such as fire ventilation systems which is especially suitable for production halls. Especially for public buildings, financing is often a major challenge, so that suitable financing models must be found. In addition, the heat input should be reduced as far as possible. This can be achieved by external shading and by reducing internal loads. Proper user behavior should also not be underestimated. The remaining electricity demand should be covered as far as possible with electricity from renewable generation. If the installation of an own photovoltaic system (PV) is not possible, energy communities offer the possibility to purchase local renewable electricity at favorable conditions.
