Reference Values of Cooling Systems in Buildings
Changing climate conditions and higher internal loads and comfort requirements lead to an increasing demand for cooling in buildings, especially virulent in cities. However, there is a lack of simple, quickly usable and practical foundations to estimate the demand for air conditioning and energy efficient cooling solutions in the planning phase. In order to provide building owners and energy planners with a simple tool to estimate the real cooling demand of buildings, this project was launched to collect cooling data and develop a cooling calculator.
The first step of the project is to gain knowledge about the general needs of building owners and companies in the field of cooling systems for buildings in order to anticipate these needs in future energy consulting and strategic planning.
After this assessment, energy consultants, energy coaches and HVAC planners should be able to determine the expected temperature increase without cooling, the (specific) cooling capacity requirement (W/m2) and the cooling demand (kWh/m2) with the help of the developed cooling calculator and a few input specifications (e.g. type of usage, building typology). Furthermore, possible efficiency potentials and cooling demand reduction measures (solar shading, natural and free cooling, hybrid re-coolers, etc.) should be identified.
