IEA SHC Task 53 Subtask B Deliverable DB.4: Technical report on system sizing and optimal control strategies

The main objective of SubTask B is to analyse and select optimized control strategies to manage the interaction between solar and cooling machine and to investigate demand/response strategies to optimise the interaction with smart grids. The latter objective is developed in the Deliverable B2, while the first is presented in the Deliverable B5. Reference buildings, energy plant layouts and control strategies used for assessing the performance of innovative systems are described in B1, B3 and B4 respectively. The aim of this report is therefore to provide information on the boundary conditions and construction typologies that have been used to simulate heating and cooling demands of residential buildings. Two approaches are presented in this document. The first adopts reference buildings: the simulation models have been benchmarked (calibrated) against the energy statistics for each of the seven climate regions based on the aggregated data for the whole residential building stock in that climate region. The second method refers to the last three cases and uses specific buildings, actually designed or monitored by project partners, which location, wall construction, windows, HVAC systems are well characterised. The reference buildings of the first approach include a Single Family House (SFH) and a Multi Family House (MFH) located in seven different European climates. The second example is a wooden Single Family House located in south Italy, therefore in a humid and warm climate. The third case is another SFH, but located in Austria, so in a Continental climate. Finally, the forth example is a MFH located in Austria with three floors and four dwellings per floor.
