  1. Sub-hourly electricity demand November 2011-March 2012 Managing energy demand from buildingsProfile, energy efficiency and the effects of climate in Bangladesh Monjur MourshedBuilding Energy Research GroupLoughborough University

  2. Project details • 3 year research project, funded by the British Council • Project partners • Rob Wilby, Department of Geography, Loughborough University • FuadMallick, Department of Architecture, BRAC University • Aims • Assess the impact of built environment on energy demand • Investigate the impact of changing climates • Develop a framework for resilient built environment in Urban Dhaka, considering: • Energy • Human comfort and wellbeing

  3. Power outage in Dhaka Dhaka during blackout Overlooking Mohakhali 02 April 2012 Immediately before blackout

  4. Context: Energy demand and generation High speed diesel (10.19%) Hydro Coal Heavy fuel oil (5%) Furnace oil 7% pa 33.7 GW 7.5 GW Gas (76%)

  5. Sub-hourly demand and generation profiles

  6. Sub-hourly shortage (outage) profile

  7. Hourly demand vs. generation profile March weekday 29/3/2012 December weekday 21/7/2012 March weekend 29/3/2012 December weekend 21/7/2012

  8. How do people cope with outages?

  9. Coping with outages: Energy storage and gen. systems Commercial Diesel gen-sets UPS Domestic Diesel gen-sets EPS – Backup power supply (~.5-1 hr)

  10. Simulation: Investigating the effects of glazing on lighting • Typical mid-rise • Location: Banani • Single leaf construction • Different glazing types • Typical office occupancy

  11. Effect of glazing type on daylighting availability Single Clear 6mm SHGC: .810 LT: .881 U-value: 6.121 Double Clear 6mm – Argon - 13mm SHGC: .698 LT: .781 U-value: 2.549 • South zone • Model parameters: • CIE clear sky • 21 July at noon Single Tinted 6mm SHGC: .427 LT: .251 U-value: 6.066 Double Low E (e=2.1) 6mm – Argon - 13mm SHGC: .564 LT: .745 U-value: 1.499

  12. Reducing lighting energy during the day: Effect of glazing South zone North zone

  13. Increasing temperature and demand for cooling

  14. Changes in mean daily temperature: More warming during winter

  15. Projected increases in cooling degree-days ~ cooling energy consumption

  16. Concluding remarks
