Energy demands for multi-family buildings in different climatic zones D1.1
This document covers the definition of reference multi-family buildings and the calculation of the corresponding energy demands to be used in the simulation framework developed in Task 1.3. The study targets two distinct scenarios: space heating (SH) dominated and space cooling (SC) dominated climates, corresponding to Northern/Central and Southern Europe, respectively. As a base for the energy demand calculations, two particular buildings representative of each zone were defined as reference cases. All the parameters, such as dwelling floor surface, insulation, etc. were set considering average values, resulting in the typical kind of construction that can be found in each zone. Additional parameters, such as number of occupants, use of appliances, etc. were also particularized so that the energy consumption is also representative of each case. Both reference cases were modelled using different simulation software. Then, several scenarios were tested in order to calculate the corresponding energy demands in various conditions. Mainly, new low-energy buildings (low space heating/cooling SH/SC demand with a significant share of domestic hot water DHW) and older SH/SC dominant buildings were simulated. The aim was to obtain different sets of conditions to further analyze the performance of the systems developed in the project when implemented in different kinds of buildings. In order to do that, relevant parameters, such as U-values or infiltration rate, were modified in the models to representative values. Reference values according to local regulations were considered when doing so. Additionally, different climatic zones were analyzed for each of the cases, so as to broaden the scope of performance and applicability studies that will be undertaken in other tasks (mainly within WP 7). For instance, the dual-source system, which is intended for Southern Europe, i.e. typically cooling dominant climates, will also need to provide heat (e.g. for the case of Madrid). For the purpose of providing the necessary data to assess such cases, the Southern European reference building was simulated also in a climate in which heating demand is significant: Bilbao. Apart from the heating and cooling demand, domestic hot water (DHW) and electric demands were calculated in order to simulate the complete system with the whole energy demand. Occupant behavior was taken into account in the calculation process. Consequently, the whole energy demand of different reference buildings was obtained for various climates. All the combinations result in energy data representative of a significant number of European buildings. This reference data will be used as an input for the design of the systems developed within the project as well as for the extrapolation to various conditions, maximizing the impact of the project. Finally, the preliminary design conditions were defined for each heat pump concept. These reference design points were defined taking into account the characteristics of each concept as well as nominal conditions derived from applicable standards.
