16469- Low Energy Building Design Presentation 2- Supply Options

This presentation by Edmund Tsang, Graham Dow, Marc Smeed, and others explores the goals and options for low energy building design, focusing on environmental, financial, and operational aspects of power supply. It highlights the importance of low CO2 emissions, sustainable operational efficiency, and the need for designs that can be maintained by non-technical personnel. The analysis includes an evaluation of various energy supply technologies such as wind, biomass, and hydro power, assessing their feasibility and effectiveness based on historical weather data and solar potential methodology.

  2. Goals for our Power Supply • Environmental • Financial • Operational

  3. Environmental • Low Co2 and other greenhouse gas emissions • Low embodied energy • Sustainable

  4. Operational • Operable by non-technical personnel or autonomous operation • Maintenance commitments must not be time consuming or expensive • Demand/comfort conditions must be met at all times • Should be efficient • Must be reliable

  5. Initial Rationalisations • Infeasible designs: • Large Scale Wind • Biomass • Hydro Power

  6. Available Technology • B+Q sell a windsave turbine £1500 • Rated Power Output: 1kW @ rated wind speed • Rated Wind Speed: 12.5m/s • Cut-in Wind Speed: 3.5 to 5 m/s @ hub height • Cut-out Wind Speed: 14 m/s@ hub height

  7. Available Technology Proven Stewarton based company

  8. Wind Data Glasgow From Paisley weather station 32m above sea level 1971-2000 averages.

  9. Solar Potential? Solar Collector facing SW @ 60°
