2009 GHG Emission Reduction Measures at SFO: 32,075 tonnes
COMPARISON
EMISSION EMISSION REDUCTIONS• 86% IS DUE TO ENERGY
CONSUMPTION• 14% OTHER
• 7% DUE TO ENERGY SAVINGS
• 91% INDIRECT REDUCTION• 2% RENEWABLE
GHG REDUCTION STRATEGY
• IMPROVE ENERGY EFFCIENCY– NEW EQUIPMENT, GREEN VEHICLES
• RESOURCE CONSERVATION– OPERATION PRACTICES
• INFLUENCE STAKEHOLDERS –PUBLIC,TENANTS,CONTRACTORS,SERVICE PROVIDERS
• RENWABLE ENERGY - SOLAR
Bottled water costs about 2000 times more than tap water.5 Can you imagine paying 2000 times the price of anything else?
How about a $10,000 sandwich?
SHORT TERM GHG REDUCTION MEASURES
• Achieve 75% Solid Waste Recycling• Complete PC Air Installation at B/A B&E
and at T2• Complete Ongoing Lighting Efficiency
Projects• Continue Fleet Vehicle Replacement
Program• Measure Fugitive Refrigerant Gas Losses• Other Measures: Green Car Rental and
Carbon Kiosks
Goal: Achieve Carbon Neutrality by July 2011 -- 9 MONTHS AWAY ….. IF
THEN WHAT?
• THIS IS A CONTINUOUS
PROCESS THAT WILL HAVE TO
BE MONITORED, UPDATED
AND MODIFIED TO CONTINUE
TO MEET THE GOAL OF
CARBON NEUTRALITY
IT WILL REQUIRE
• MANAGEMENT COMMITMENT
• POLICY CHANGES
• RESOURCES
• STAKEHOLDER BUYIN AND PARTICIPATION
• EDUCATION AND ENCOURAGEMENT
Medium and Long Term Recommendations
• Continue Lighting Efficiency Measures
• Install Additional Solar Panels with SFPUC Funding
• Replace an Outdated Chiller Unit at the Central Plant
• Replace Outdated T3 Fan Room Equipment
• Procure More Efficient Hybrid and Electric Vehicles
• Reduce Vehicle Idling Time through Employee Education
Medium and Long Term Recommendations (Continued)
• Install Computer Sleep Mode Software• Replace Desktop Computers with Laptops• Develop a Data Warehouse at SFO• Erect a Greenhouse over Biosolids Drying
Beds• Obtain O&M LEED Certification for Terminal
Complex• Develop O&M Plan for Terminal Complex
OTHER LONG TERM GHG EMISSION REDUCTION MEASURES
• Further Improve the Efficiency of Terminal Complex HVAC System
• Improve HVAC System Efficiency in other SFO Buildings
• Further Reduce Fuel Consumption at SFO• Evaluate Digester Gas Reuse Options• Further Enhance Solid Waste Recycling• Minimize Refrigerant Gas Emissions
INFLUENCE STAKEHOLDERS
• GREEN RENTAL CARS• SUSTAINABLE FOOD• CARBON KIOSKS• GREEN CONTRACTORS• GREEN TENANTS
Chiller #2 – Installed in 1978
Existing supply fan in B/A E. Installed 1978. It is about seven feet tall and perhaps ten feet long. This one fan serves half the boarding area If it fails, then half the boarding area is without ventilation until the unit is repaired. For a catastrophic failure, it could be at least a week of no ventilation.
Fan Wall Fans like those installed in T2. Typically these box fans (3 ft by 3 ft) are in arrays of 3 by 3 (or 4 by 4). If one fan fails, the others pick up the load and supply normal ventilation. They are run by a VFD to maintain all fans at a uniform speed to maintain static pressure at setpoint.
