Bill Harrison Cleveland - Akron Chapters Joint Meeting March 16, 2009
Challenges • Energy – cost and availability • Food – cost and availability • Protecting the environment
ASHRAE • 52,000 members in 130 countries • 170 chapters in 24 countries • Associate Societies in 32 countries • 2500 members active on committees
Energy • Cost and availability • IEA: $100 / Barrel till 2015; $120 till 2030 • End use in developed economies • Buildings – 40% • Transportation 28% • Industry 32% • Coal and oil primary energy sources • 45% Growth between 2006 and 2030
Food • Cost • Energy driven costs • Spoilage • Availability • Cost and spoilage • Foodstock diversion • Refrigeration – large energy consumer
Environment • Buildings use 70% of electricity • Extensive emissions from generation • Water use for generation • 45% Emissions growth 2006 to 2030 ASHRAE role: Take energy out of buildings
Energy Waste A Real Problem… A Real Opportunity
Sustainability for ASHRAE Energy Efficiency And Healthy and Productive Indoor Environments
Improved Operating Strategies • Energy Systems Lab - Texas A & M– Save 10% to 40% energy • World Energy Forum: 17% Internal rate of return for energy efficiency upgrades • Not product centered • Software and expert knowledge focused • Limited knowledge distribution
Improved Operating Strategies • Lack of standardization • Minor changes use major energy • Wrong incentives for operators • No training programs
Chilled Water Plant Strategies • Rightsizing equipment • Variable Primary Pumping • Optimized condenser water • Temperature • Flow • Thermal storage • Model energy - track energy • Periodic re-commissioning
Energy Conserving Strategies • Envelope testing • Pressure tests • Infrared Scans • Return to design conditions • Scheduling review
Operator Training • Local chapter program • HVAC fundamentals • High performance products and systems • 1980’s training produces 1980 results
The Cost of Owning HVAC • Capital costs • Utility costs • Repair costs • Replacement costs • Maintenance costs
Maintenance Plans • ASHRAE Guideline 4 – 2008 • Preparation of Operating and Maintenance Documentation for Building Systems • CIBSE Guide M – 2008 • Maintenance Engineering and Management • Must include energy budgets and energy reporting
Maintenance Strategies • Develop proper documentation • ASHRAE Guideline 4 • Keep equipment clean • Don’t accept dirty equipment • Maintenance management software • Monitor energy use • In house / outsource • Training capabilities
Sustainability Challenge • Six of top ten energy measures under control of architects • Integrated Building Design process essential • Communication - collaboration • “First Cost” mentality • Engineers: evil enablers
Owner Organizations • Building Owners and Managers Association • International Facility Management Association • APPA – The Association of Higher Education Facility Executives
Owner Issues • Life Cycle Costing • Equipment room sizing • Engineers need to deliver energy message • Energy cost implications • Building Commissioning

High Performance Building Design Energy Modeling Building Narrative
High Performance Building Design A larger budget for planning and design produces lower construction costs and lower operating costs
ASHRAE’s Role • Net zero design guidance by 2015 • Building Energy Labeling • AEDGs to reduce energy in existing buildings • Affordable and maintainable refrigeration systems • Efficient refrigeration systems
ASHRAE Chapter Actions • Schedule a meeting with local owner organizations • Integrated Building Design • High performance design costs more • Keep your Green Buildings Green • Get comfortable with building energy benchmarks:“What’s your EUI?” • Walk the talk – how is your building being operated?
The Buildings Business • Largest user primary energy • Improved building operations • 10% to 40% energy savings • Local educational programs by ASHRAE chapters • Keep our green buildings green
World Population Growth • 2008 - 6,700,000,000 • 2050 – 9,200,000,000 Growth: 2,500,000,000 People
Per Capita CO2 Emissions • World: 4.3 Metric tons/person • OECD Nations: 11 Metric tons/person • USA: 19 Metric tons/person • Grow from 2 t0 6 “Americums” Global CO2 Emissions 2009: 30 Billion metric tons 2030: 42 Billion metric tons
Atmospheric CO2 Levels • Pre-industrial: 280 PPM • 2007: 380 PPM • 2050 Business as usual: 580 PPM Can we afford to take a chance?
The Cost of Being Green • Energy Efficiency - $170 Billion • Smart Grid - $8.6 Trillion • Energy Storage - $180 per Megawatt hour • Carbon Capture and Sequestration - $ ??? • Priced carbon emissions - $ ??? • $450 - $600 Billion per year until 2030 Estimates for global mitigation from “Green Investing” - 2009 WEF
The Cost of Being Green • 2006 Global Emissions: 28,000,000,000 MT • 2006 USA Emissions: 5,700,000,000 United States Share: 20% • Global cost of mitigation: $10,500,000,000,000 • US Share: $2,100,000,000,000 What is the cost of taking energy out of buildings?
