By reducing the energy needs for heating and cooling, the local renewable energy production can be used for addressing other buildings end-uses (lighting, ventilation, appliances) which are less dependent on seasonality, thus reducing the yearly mismatch between the PV production and the buildings’ energy use. The LowEx system is integrated by using the existing infrastructure, thus saving cost and embodied energy from material use. The same can be said about the use of a common system for heating and cooling, resulting in less need for piping and heating and cooling emitters. The use of high temperature cooling makes it possible to utilize free cooling from the energy wells to a much larger extent than in traditional systems, because cooling from the wells can be directly utilized even when the temperature of the water from the borehole rises towards 19 °C. This technology is interesting for many actors as it reduces the need of energy from the grid, it is clean, and the energy can be applied directly to use efficiently. The technology has scaling potential as it reduces the energy cost for building owners. Hence the constructors, architects and service providers will benefit from more practical knowledge about the technology to be able to provide it to meet the demand.
