Low Energy Building Design Group B

This project focuses on the design of a low energy building in remote Scotland, structured as student accommodation. Comprising 16 bedrooms, a common kitchen, lounge, and library, the design is subdivided into four zones, each consisting of modular elements. Occupancy varies from 52 in summer to 16 in winter. The demand profiles are modeled through simulations to optimize energy consumption for heating, cooling, lighting, and hot water. The energy supply incorporates wind energy and thermal storage to better align with these demand profiles, aiming for a sustainable balance in power usage.

  1. Low Energy Building DesignGroup B Embedded Generation Romain Jauffres, Karen Kennedy, Pedro Ros Zuazua, Ulrich Sanson

  2. The building • Living area of a Research Centre • Located in remote Scotland • Can be considered as a student accommodation place • 16 Bedrooms • Common kitchen • Common spaces: a lounge and a library Group B: Romain Jauffres, Karen Kennedy, Pedro Ros Zuazua, Ulrich Sanson

  3. The Design • Made up of four different zones: bedrooms, kitchen, lounge and library. • Each zone is composed of modules • Occupancy: • 52 during Summer (June 1st to August 31st), • 16 during Winter (September 1st to May 31st) • Linked with a work building. Group B: Romain Jauffres, Karen Kennedy, Pedro Ros Zuazua, Ulrich Sanson

  4. Demand profiles • profiles generated via simulation program ESP-r • they focus on weekdays and weekends demand during winter and summer time • Simulation are based on typical weeks for winter and summer, results are for one day of these typical weeks • the model simulated is made up of 4 zones • Profiles: space heating/cooling, small power, lighting, water heating Group B: Romain Jauffres, Karen Kennedy, Pedro Ros Zuazua, Ulrich Sanson

  17. Supply Matching Supply Sources to Demand Profiles Utilising thermal storage e.g. rock stores, hot water, we are able to shift the times when we use the Heat Pump. Group B: Romain Jauffres, Karen Kennedy, Pedro Ros Zuazua, Ulrich Sanson

  18. Supply Matching Supply Sources to Demand Profiles The use of geothermal requires 1/3 power to heat e.g. 6kW heat pump uses 2kW Group B: Romain Jauffres, Karen Kennedy, Pedro Ros Zuazua, Ulrich Sanson

  25. Supply Matching Supply Sources to Demand Profiles Group B: Romain Jauffres, Karen Kennedy, Pedro Ros Zuazua, Ulrich Sanson

  26. Conclusion At present the Power Supply and Demand profiles are very mismatched, by continuing to work on demand side management and also looking at methods of power/energy storage we hope to be able to create a better match.
