  • 1. Carbon Footprint of EuroVillage CompoundAhmad AlqahtaniProf. GoodeE-16May 2012

2. Agenda Description of Euro Village (EV) Sources of Emissions Methodology GHG emissions GHG reduction plans Improving the inventory2 3. Description EVA fully serviced residential/office complex locatedin Khobar, Saudi Arabia Built in 1975, multiple expansion 80s, 90s, 00s. Purchases electricity from the Saudi ElectricityCompany Desalinates water onsite using RO Consists of: 470 villas one school 6 office buildings one nursery 2 hotels one gym 3 workshops 5 kitchens (dining halls)3 4. Description EV80s villa90s villaEuroInn (built in 2005) Office building 4 5. Description EVOver 6000 Electric bill5 6. Sources Sources of emissions ScopeType of source GHG emissions Sources1Stationary Combustion CO2, CH4, N2O Kitchens uses LPG for cooking Mobile Combustion CO2, CH4, N2O Trucks, pickups, buses and cars Fugitive EmissionsHCFC-22 CFC-11Refrigerators and ACs2Purchased Electricity CO2, CH4, N2O SEC power plant3Employee Travel CO2, CH4, N2O International Flights6 7. Methodology Approach Operational control - full control over the operational policies. All facilities are run and managed by EV All offices and 4 out of 5 kitchens are leased EV responsible for all bills and maintenance One exception is LPG for leased kitchens7 8. Methodology Datacollection Scope 1 LPG bills Freon gas usage records Diesel and gasoline annual consumption Distance traveled was estimated Scope 2 Over 6000 Electric bills. Scope 3 Vacationschedule8 9. Methodology The GRP methods Scope 1 StationaryCombustion Tier C method Emission factors for fuel type (natural gas) and commercialend user to calculate CH4 and N2O emission factors Mobile Combustion Tier B for CO2 emissions and tier C for CH4 and N2O Distance traveled estimated. FugitiveEmissions Tier A method GWP cited from California Environmental Protection Agency. 9 10. Methodology Continuethe GRP methods Scope 2 Electricity Tier B Method. Emission factors were cited from EIA Scope 3 EmployeeTravel Calculated using 10 11. GHG Emissions Totalemissions The total emissions released by EV in 2011 was 53,767metric ton of CO2 equivalent Purchased electricity + fugitive emissions = over 99% Scope Emission categoryEmissions (mtCO2e)% of total emissionsStationary Combustion230.04% 1Mobile Combustion 2360.44%Fugitive Emissions6,156 11.45% 2Purchased Electricity47,272 87.92% 3Employee Travel800.15% Total 53,767100.00%11 12.

Reduction Tracking and Accounting Tracking Install a meter at every unit link bills to the consuming unit Accounting Record monthly consumption per unit Monitor and identify most energy intensive 17 18. Reduction EnergyAudit Blower Door Test Air tightness test Thermographic Scan Heatloss measurement Record wattage from labels of all appliances18 19. Reduction Energy Efficiency Construction Invest in thermal envelope (wall, roof, air/vapor retarders Intensify weather-stripping and sealing Low U-factor windows can save up to 25%19 20. Reduction EnergyEfficiency Air Conditioning Roughly26% of total electricity consumption Replace ACs older than 20 years with high SEER to save at least 20% of cooling costs Include filter cleaning or replacement to improve the efficiency by 5% 20 21. Reduction Energy Efficiency Energy Star Appliances Thousandsof electrical appliances, at least 13 per a unit. Look at labels for the most efficient 21 22. Reduction Replacement of HCFC-22 & CFC-11 HCFC-22 Replace with R-134a CFC-11 Replace with HFC-12322 23. Suggested Target Suggestedtarget 20% reduction by 2020 Will result in reduction of over 10,000 mtCO2e Quick wins ACs filter maintenance = 1% Replacing CFC-11 = 1% Replacing HCFC-22 = 1% 8 year investment plan More efficient ACs = 7% reduction Improved construction = 5% reduction More efficient appliances = 5%23 24.
