Applying Existing Solutions in European Buildings for Carbon Savings

While decarbonisation is the main objective of the RES4BUILD integrated energy solutions, decoupling from fossil fuels contributes to security of supply, and using on-site generated electricity contributes to affordability, moving away from heavily fluctuating market prices. A report has indicated the technical potential of these integrated energy systems in the European market,

Research Need

Never has it been more important to ensure that Europeans can cover their buildings energy needs in an affordable and environmentally friendly way. The RES4BUILD project aims to decarbonise the energy consumption in buildings by developing integrated renewable-energy-based solutions; incorporating heat pumps, combined solar photovoltaic-thermal technologies, thermal energy storage and smart management o produce low to zero carbon heating and cooling. While decarbonisation is the main objective, decoupling from fossil fuels contributes to security of supply. In addition, using on-site generated electricity contributes to affordability and moves away from heavily fluctuating market prices.

The pilot systems are operating in Greece, Denmark and Belgium. Simultaneous work has assessesed the potential impact of this integrated energy system from a decarbonisation point of view.

European Market Research and Modelling

The integrated system design is tailored to the needs and requirements of the users. These are are generally defined by the building typology. Additionally, location and energy performance of such building typologies affects the system design. RES4BUILD partners ARUP completed a market assessment to understand the potential project impact.

The partners built a blueprint of the EU building stock from existing data bases and additional relevant research projects. The four selected building typologies characterise approx. 86% of the total EU building stock floor area, across four climatic regions. The RES4BUILD system operation and energy consumption was modeled based on typical building energy demand profiles. Thermal energy demand was then optimised using ‘smart-buildings’ control algorithms.

Impact Assessment

By applying these results across the European market, implementing the RES4BUILD system could lead to a 75% reduction in fossil fuel usage and CO2e. The potential for a major reduction in building energy related CO2 emissions is considerable. However, research on the local market and regulatory drivers, as well as the cost and social impacts of adopting these technological solutions is required.

Although this indicates the technical potential of integrated energy systems in the European market, the actual impact depends on the reach to building owners, tenants and investors. This impact study is a prelude to the wider market analysis, which is currently ongoing.

RES4BUILD

RES4BUILD will decarbonise the energy consumption in buildings by developing integrated renewable energy-based solutions that are tailored to the needs and requirements of users and installers. The consortium works to: Improve the performance and reduce the cost of the most innovative components of the RES4BUILD solutions; Develop tools for simulation, sizing and control, making optimal use of integrated energy systems and the flexibility of consumption, while respecting the wishes of end-users; Engage all relevant stakeholders in an interactive process to co-design integrated energy systems that suit current needs and future expectations; Test and validate various RES4BUILD solutions in different climates; and Pave the way for bringing the developed solutions to the market using rigorous life cycle assessments to measure their real impact, ensuring wide adoption.
