Audience – for now, we are going to assume that the audience are people who are somewhat familiar with our industry – we will work on a separate piece for those folks who want to make presentations to the general public. My deadline
to get this to the BOD is Monday

Today’s building designs mortgage the energy future
of the United States.

Need to Save Energy
• World energy consumption is projected to grow by 71 percent from 2003 to 2030 (U.S. Energy Information Agency)
• Oil is forecasted to remain dominant energy source with coal forecasted as primary fuel for generating electricity – Cost of oil in 1976 vs. now (getting figures from Gordon)
• Energy use increasingly shifting away from developed countries and becoming more carbon-intensive

Why ASHRAE?
• ASHRAE developed the first energy conservation standard in the U.S. at request of the federal government during the 1970s energy crisis
• Standard 90.1 now serves as the national reference for state commercial building energy codes through the U.S. Energy Policy Act
• ASHRAE continues to provide a wealth of technical and engineering information, including Standard 90.1, to help engineers reduce energy use
• ASHRAE has a long history in energy conservation and is committed to economic energy-efficiency standards and advanced guidance

Who We Are
• Help keep indoor environments comfortable, productive and energy efficient
• Deliver healthy food to consumers• Preserve the outdoor environment • 50,000 volunteer members in 133 countries• Consulting engineers, contractors, manufacturers,
manufacturing representatives and architects

Net-Zero Energy Buildings
Buildings which, on an annual basis, use no more energy than is provided by on-site renewable energy sources.
![Page 8: Note – we are having a title slide and a background slide created – for now, please focus on copy](https://reader036.vdocuments.us/reader036/viewer/2022062309/5681574f550346895dc4f1de/html5/thumbnails/8.jpg)
Challenges
• Establish carbon-neutral buildings by the year 2030
• Design buildings that use substantially less energy, reduce greenhouse gas emissions and create spaces that are healthy and comfortable
• Many high-performance buildings exist today that exceed minimum energy requirements by over 50 percent – yet aggressive research and development needed to achieve feasible, cost-effect net-zero-energy buildings
![Page 9: Note – we are having a title slide and a background slide created – for now, please focus on copy](https://reader036.vdocuments.us/reader036/viewer/2022062309/5681574f550346895dc4f1de/html5/thumbnails/9.jpg)
Guiding Principles
• With new buildings adding only 2% to the stock each year, we must emphasize improvements to existing buildings
• Standard 90.1 provides the code minimum, which must meet widespread consensus in the marketplace as the requirement for all new buildings
• Above-code documents can lead the market by providing means to voluntarily exceed code minimum requirements
![Page 10: Note – we are having a title slide and a background slide created – for now, please focus on copy](https://reader036.vdocuments.us/reader036/viewer/2022062309/5681574f550346895dc4f1de/html5/thumbnails/10.jpg)
Factors at Play
• How exactly do we define net-zero?
• Net-zero-energy buildings cannot be achieved by energy efficiency alone – renewable energy applications must be applied
• Standard 90.1 only influences the design of new buildings – actual performance of occupied building depends on many operating and maintenance factors – therefore actual EUI will differ from design EUI. Measured data is essential to verify performance

How Will We Do It?
• Standards• Research• Special Publications
![Page 12: Note – we are having a title slide and a background slide created – for now, please focus on copy](https://reader036.vdocuments.us/reader036/viewer/2022062309/5681574f550346895dc4f1de/html5/thumbnails/12.jpg)
Standards
• Standard 90.1-2010 – goal is 30 percent improvement over 90.1-2004
• Standard 189.1P – Design of High Performance Green Buildings Except Low-Rise Residential Buildings
![Page 13: Note – we are having a title slide and a background slide created – for now, please focus on copy](https://reader036.vdocuments.us/reader036/viewer/2022062309/5681574f550346895dc4f1de/html5/thumbnails/13.jpg)
Special Projects/Publications
• Advanced Energy Design Guides – provide 30 percent energy savings over Standard 90.1– Small office buildings– Small retail buildings– Warehouses– Kindergarten through
grade 12 schools
![Page 14: Note – we are having a title slide and a background slide created – for now, please focus on copy](https://reader036.vdocuments.us/reader036/viewer/2022062309/5681574f550346895dc4f1de/html5/thumbnails/14.jpg)
Special Projects Steering Committees
• Building Performance Protocols• Carbon Emissions Calculation Tool• Building Information Modeling and Interoperability

ASHRAE is committed to providing aggressive energy efficiency improvements in buildings. While Standard 90.1 provides the
code minimum, ASHRAE will provide beyond-code guidance through documents such as the Advanced Energy Design Guide
series. The ultimate goal is net-zero-energy buildings.
