Guidelines to calculate the annual energy balance of a PED. D4.2
report
Calculation of energy balance in positive energy districts is complex since it includes several parameters regarding RES on-site, primary energy factors, deciding if a resource is an input or not for calculation and so on. In order to reach an annual positive energy balance, buildings involved in the district have to manage their energy consumption and the energy flow between them and the wider energy system. The system and the interaction between the buildings should make optimal use of elements such as advanced materials, local RES, local storage, smart energy grids, demand-response, cutting edge energy management (electricity, heating and cooling), user interaction/involvement and ICT. Calculation methodology for annual balance may be generated following a few steps. First, energy sources and resources within the limits of the district need to be studied. Once both analyses are done, an iterative process and examination of energy balances will result in different alternatives for the district. In order to assess how positive a certain district is, the balance is made in primary energy terms, as it compares different type of energy and considers the benefits within and beyond the limits of the district. To calculate energy balance, the appropriate assumptions need to be realized (i.e. primary energy factors, average efficiencies of the systems, etc.).
