losses of the DH network and a higher utilization of the plants. The concept of low temperature DH in combination with renewable heat sources can be an important player for meeting the goals of limiting greenhouse effects set forth at the COP21 meeting and a feasible way towards achieving the future sustainable renewable energy system.
In the longer run, building energy renovations, like replacement of windows and typically insulation of ceilings, lead to a reduced energy consumption, allowing reduction of the DH net temperatures from the perspective of energy capacity. Anyhow, low temperature DH focuses on the general temperature level, but increasing the temperatures in the network when the ambient is very cold is an obvious option to optimize the network investment and operational costs. Conclusion 4th generation DH is an important step leading to increased efficiency of the system, including reduced thermal distribution

It is hardly a secret that the sun does not always shine in Denmark. That is why the construction of a seasonal thermal store, where the energy can be deposited until needed, is valuable. On sunny days, the heat is absorbed in water in a pit and saved for district heating consumers to use during autumn and winter. This 200-million- litre/5.3-million-gallon pit, the largest in the world, has been designed for Vojens District Heating by Ramboll.
THIS PIT REDUCES CO2 BY 6,000 TONNES (AND SAVES 10% ON THE HEATING BILL)
