5 General description of the method - Output of the method This method covers the calculation of
« thermal loss of the distribution system for space heating, space cooling and domestic hot water in the zone;
« recoverable thermal loss for space heating, space cooling and domestic hot water in the zone;
« auxiliary energy demand of distribution systems;
« recoverable auxiliary energy in the zone for space heating, space cooling and domestic hot water in the zone;
« recovered auxiliary energy in the fluid in the zone for space heating, space cooling and domestic hot water in the zone. The time step of the output can be according to the time-step of the input values: — hourly; — monthly; — yearly. All input and output values are mean values in the corresponding time step. Because of summarized time steps with the same boundary conditions the bin-method is also valid. 6 Calculation of heat losses and auxiliary energy of distribution systems 6.1 Output data The output data of this method are listed in Table 4: Table 4 — Output data of this method: Description Symbol Unit Validity interval Intended destination module Varying Temperature of DHW ÍWend °C 30.70 M8–1 YES Thermal loss of the distribution system for heating in the zone QH,dis,ls kWh

This method does not take into account any dynamic effect. 6.3 Input data 6.3.1 Product technical data (quantitative) According to the EU-Regulations circulation pumps (wet running meter) are certified with an energy efficiency index EEI (see Table 5). The EEI-value is determined by a measurement procedure. If the EEI of a real pump is known it can be taken into account.
Other circulation pumps are not included in this regulation. SIST EN 15316-3:2018

The bin-method can also be used because in this method only identical time steps are summarized. No dynamic effects are explicitly taken into account because there are no significant time constants. This procedure is not suitable for dynamic simulations. 6.4.2 Operating conditions calculation 6.4.3 Heat loss calculation The heat loss calculation of a distribution system is based on the mean water supply temperature, the surrounding temperature in a space, the thermal transmittance of the pipes, the length of the pipes and the operation time.
