Transcript Advanced Energy Conservation 101: Understanding the

Note – we are having a title slide and a background slide created – for now,
please focus on copy
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.
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-zeroenergy buildings
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
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
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
Special Projects/Publications
• Advanced Energy
Design Guides – provide
30 percent energy
savings over Standard
90.1

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.
