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.

Potential and feasibility study for heat supply in Aesch
The municipality of Aesch (BL) is developing a climate-friendly, economical and secure heat supply for households and businesses. The aim of the municipality is to achieve the national climate targets (net zero by 2050) and build a sustainable energy infrastructure. As part of the feasibility study, renewable energy sources for heating and hot water, including geothermal energy, local and district heating solutions and air-to-water heat pumps, were analysed. TEP Energy analysed their economic viability and possible implementation in various sub-areas. The study was carried out in collaboration with eicher+pauli, the municipality of Aesch and the Basel-Landschaft Office for Environmental Protection and Energy and forms the basis for the municipality's heat planning.
