ASHRAE
Building EQ Energy Ratings
Why- It makes good “business sense”;May 2014 “bEQ” Journal Article ……
• ASHRAE is committed to helping its members navigate the uncertain waters of great change and strives to create competitive advantages that will result in higher margins and a higher quality end result. A compelling example of ASHRAE’s commitment can be found in its new Building Energy Quotient (bEQ) program. The bEQ program creates a more holistic approach towards energy performance and helps our clients make better decisions that produce long-term benefits in a rapidly changing environment. (by, Ross Montgomery & Tim Wentz)
Why..Buildings Represent• 17% of fresh water consumption
• 25% of wood consumption
• 39% of CO2 emissions
• 30% of waste generation
• 40% of energy use
• 55% of natural gas use
• 72% of electrical energy use
Total global energy consumption in 2007 was 145 trillion kWh
(495 quadrillion British thermal units [Btu])
Why …….?
• Most of world energy consumption is from fossil fuels
• OIL is forecasted to remain dominant energy source with COAL forecasted as primary fuel for generating electricity
• According to the Energy Information Agency, worldwide
energy consumption is expected to increase 1.4% per year through 2035, implying that buildings will
consume 86 trillion kWh (296 quadrillion Btu) by the year 2035
(EIA 2010).
34
Buildings account for approximately 40% of the worldwide
annual energy consumption (WBCSD 2009). meaning the
buildings sector consumed about 58 trillion kWh (198
quadrillion Btu).
(Cooling/Heating) and (Lighting) typically make up nearly 75% of an office building’s KWhr usage
Why; Buildings use a lot of Energy
(WE can make a difference)
Why? Atmospheric CO2 Levels and Emissions
• Pre-industrial: 180 - 280 PPM
• 2007: 380 + PPM
• 2014; 400 PPM
• 2050 Business as usual: 580 PPM
CO2 Levels are
Rising too fast !
? Global Warming and Cooling ?
Scripps Institution of Oceanography shows a record-breaking amount of CO2 in our atmosphere.
• New tests show the level of carbon dioxide CO2, is now at its highest in human history.
• In April 2014, the gas measured more than 400 parts per million each day,
• much of the rise in carbon dioxide has come about in the past 100 years."Humans have caused carbon dioxide concentrations to rise over 90 percent of that in the past century alone."
• "The rate of increase has accelerated from about 0.7 ppm per year in the late 1950s to 2.1 ppm per year during the last decade."
• It's clear if we keep on the same course we're heading for a very different world. That carries with it lots of risks. If the climate changes fast enough, those risks are compounded."
• Most buildings will lose up to 30% of their energy efficiency in the first three years of operation
• Construction budgets versus M&O budgets?– Deferred Maintenance
– Budget cuts

Performance Index/Rating• What is measured?
– Source energy
(notates “site energy” and “energy cost”)
– On-site renewables
– Emissions
• It’s a “sea of thought change”: that we can measure the performance of the buildings as they were designed, built, then operated.

What is the “Building EQ Rating Scale”
(Intuitive and Simple)
• Compare • Scale
• The bEQ scale is dimensionless
• Zero point on scale set to “zero net energy”
• Score can go below zero for net energy producing buildings
• Median value (100) set to national median EUI of CBECS for that building type
• Bottom half of scale exceeds 115 for “inefficient” and “unsatisfactory” high energy usage
Scale Range
Rating Description

What types of Ratings can
Building EQ Deliver ? ? (Commercial Buildings):
•«As Designed
(asset)»
• «In Operation
(operational)«
Building EQ As Designed
Features
The As Designed Rating (asset) provides a rating of
the building based on the components specified in the
Design—including mechanical systems, building
envelope/enclosure , orientation, and daylighting. The
asset rating will be based on the results of a
standardized BUILDING ENERGY MODEL as
compared to a baseline (using building use and geo-
location-climate zone).
– Applicable to both new and existing buildings (less than
12 months old)
– Must be viable designs and intended for construction

As-Designed……..“Asset”
• Very important concepts:
• “Shows off ”, “Highlights” the “ASSET” value of the
building
• Tells the user, “What it can do” , “What it is designed to
do”
• Used for financial valuations, appraisals and sale or lease transactions since
they are more dependent on long term performance of a building
• An Asset Rating is evaluated at a single point in time and is a long termmetric since its drivers change very infrequently (once in perhaps 10 years
when buildings undergo a major retrofit).
• Excellent “comparison” (asset vs operational) about what it is designed to
do versus what it is actually doing.
Building EQ As Designed Features
Assessment of energy performance potential,
based on building’s physical characteristics and
systems
Independent of some buildings occupancy and operating
conditions– Based on an energy model that normalizes for operational variables using standardized inputs and schedules (provided in
Building EQ workbook)
– Improves consistency in rating comparisons with known values for HDD,CDD,setpoints,schedules, fuel
mix,etc.
– Improves consistency comparing like buildings from climate zone to climate zone
• Note: Does not predict actual building energy consumption because some
operational and occupancy parameters are not customized to the candidate building.

Building EQ As Designed Process
(EUI standardized(candidate) / EUI median(baseline)) x 100
(Your Building) (From Energy Star/Portfolio Manager or
ASHRAE Standard 100 EUI Targets)
• Compares standardized modeled energy use of candidate building to median/baseline EUI
• Uses specified modeling inputs of certain building operating parameters
• The median EUI for all building types now determined using methodology from Oak Ridge National Laboratory paper ORNL/TM-
2014/215 – Derivation of Building Energy Use Intensity Targets for ASHRAE Standard 100 from August 31, 2011
Now lets see the “In Operation” portion of Building EQ
Building EQ In Operation
Features
The In Operation Rating (operational) provides
a rating based on the measured “metered”
energy use of a building-------- being the
combination of the “Assessment of energy
performance with the existing characteristics and
how it is operated”
• Operational Rating is based on day-to-day operations of the
building and measures the operational performance of a
building that are affected by the building’s operating schedule,
occupant behavior, HVAC system performance and equipment
and lighting loads (in the context of the specific building’s
geometry, equipment and local climate).
– Applicable for existing buildings and after 12-18 months
of operation for new buildings
Building EQ In Operation Features
• Includes an ASHRAE Level 1+ Energy Audit
– Recommends actions to reduce energy use
– Identifies both peak demand reduction and energy management opportunities
– Recognizes energy use from on-site renewables
– Actionable recommendations for improving energy performance
• Site visit and photos required
• Includes measurement-based IEQ indicators to assure levels of service
are maintained (no gaming; Confirms that indoor environmental quality is not
compromised for energy savings

– Added thermostats and occupancy sensors for exhaust and supply fans
– Adjusted time schedules for better tracking of occupancy
– Reset hot water set points of back-up water heaters to 100ºF allowing greater efficiency of solar panel heating.
Case Study EEM’s(#2)
• Energy Efficiency Measures (EEM):– Interlock toilet (TEF) exhaust and
ventilation (OAU) operation during actual occupied times, etc.
– Increase shading-outside and inside window/door weatherization treatments.
– Add occupancy sensors to lighting to turn off when not needed.
