Energy Systems Research Unit Low Carbon Energy Systems

Energy Systems Research Unit Low Carbon Energy Systems Expertise Nick Kelly, Assoc. Director, ESRU.

OVERVIEW • multi disciplinary research team with a focus on low carbon energy systems at all scales (individual building – city scale) • designated BRE Centre of excellence in energy utilisation • group has expertise in – – energy systems modelling and simulation developing software tools for energy professionals developing and testing low-carbon technologies performance monitoring of buildings, microgeneration, heating, cooling and ventilation equipment

MODELLING AND SIMULATION • ESRU develop the Open Source ESP-r tool - used to analyse performance in domestic and non-domestic buildings • detailed simulation engine that can be used to simulate thermal performance of any existing building or building design • also models and simulates the performance of the heating, cooling, ventilation and other energy systems (e. g. renewable generation) in detail • used extensively in consultancy for modelling of technically challenging building and systems • ESP-r has been applied in the modelling of – low carbon schools offices and hospitals – passive houses – domestic heat pumps – combined heat and power (CHP) – trigeneration – fuel cell CHP – PV solar facades – advanced glazings – solar heating and cooling

SOFTWARE TOOLS • ESRU produce a range of other software tools including – MERIT – energy demand supply matching and sizing tool – ENTRAK – customisable energy information system with ability to capture live data – HUE – housing upgrade evaluation tool • the group also develops software for 3 rd parties – Biomass Design and Sizing Tool for Carbon Trust – IDEAS domestic heating/cooling controls test environment for CIBSE – City Electrical Demand Modeller for Scottish Power Energy Networks – used to analyse impact of electrified heating – ADEPT for detailed modelling of heating systems for controls manufacturers

LOW CARBON TECHNOLOGIES • ESRU have been involved in field trialling, testing and development of a range of low-carbon technologies – – – photovoltaics (PV) solar facades air source heat pumps combined heat and power (CHP) PEM fuel cells boiler controllers automated heating load-shift controllers smart plugs smart homes technologies low-cost pervasive sensing high-performance storage heating phase change thermal storage

PERFORMANCE MONITORING • ESRU have extensive experience of building performance monitoring including: – – – BRE innovation park Lighthouse Glasgow City Council Housing Refurbishment Shetland low carbon heating (NINES) Heat pumps (Findhorn, West Lothian Council) – – blower door testing (air tightness) temperature, RH and indoor contaminants electrical demand monitoring of outdoor climate (solar, wind speed, etc) • Testing and monitoring capability • Group also helps develop and apply the Build. AX range of low cost environmental sensors and loggers

RESEARCH PROJECTS example research projects: • International Energy Agency (IEA) projects on microcogeneration for domestic applications; validation of whole building thermal modelling programs; influence of user behaviour on building energy use • EU projects: passive solar systems (PASSYS); passive cooling (PASCOOL); internet-based building eservices (Smart. Homes); community based supplydemand matching (ORIGIN); addressing building design/actual performance gap (HIT 2 GAP); design and evaluation of exemplar renewable energy districts (RUGGEDISED) • UK projects (EPSRC): Top and Tail Grand Challenge in Energy Networks; pervasive sensing for collaborative facilities management; Fabric integrated thermal storage in low carbon dwellings (FITS-LCD).
