Background

• Research is a part of Annex 54 from the IEA− Integration of Micro-Generation and Related Energy Technologies in Buildings”

• The Netherlands, Eindhoven participates in 54 subtask B− Use simulations to develop an extensive library of performance studies and

synthesis techniques to identify generic performance trends and “rules of thumb” regarding the appropriate deployment of micro-generation technologies.

Research question

• “How to develop a design concept which ensures the comfort of the occupants, and has an optimized (system) performance of an energy system with 100% renewable micro-generation technologies which has to satisfy the electrical and thermal energy demand, for an off-grid campground at Texel, in the Netherlands?”

Priority steps

• Reducing the CO2 emissions

• Direct use of the generated renewable energy• Use the renewable energy source which has the

most energy contribution throughout the year regarding the demand profile

Expected results

• Predefined outcomes from the IEA Annex 54− Compilation of case studies of the introduction of micro generation technologies− Country-specific studies on the performance of a range of micro-generation systems.− Studies of the viability of micro-generation systems in different operational contexts and of the

impacts of micro-generation on the wider community and the potential benefits, in particular for the electricity network.

− Performance assessment methodologies.− Component models and their implementation in building simulation tools.− An update on occupant related DHW and electric load profiles.
