B3: Step-by-step

B3 Basics
B3 = Buildings, Benchmarks, and Beyond

Uses engineering algorithms to model how much energy
buildings should be using based on current building code.

2000 – B3 Sustainability Guidelines
developed

2002 – Law c398-H.F. No.2972
enacted

2004 – MNBenchmarking.com
launched6

2011 – Coming soon, redesign!


B3: Step-by-step

B3 Poll
How confident are you in your ability to utilize B3?

A. Very – I can input building and utility data and use the reporting tab.

B. Fairly – I can input building and utility data.

C. Somewhat – I can input utility data, but not much else.

B3 Step 6: Utilize B3 Extras
• “Versioning” – when adding space/renovating create a new version so that
energy use is comparable across time

• “Energy Star” – the EPA’s energy rating system, provides a score based on
“statistically representative models that are used to compare your building
against similar buildings from a national survey conducted by the
Department of Energy’s Energy Information Administration.”
EPA Energy Star Portfolio Manager


B3: Step-by-step

B3 Review
1. Profile – Enter complete building profile data.

2. Utility data – Enter complete utility data.

3. Focus building - Determine the focus building.

4. Energy type – Understand the energy make-up of the

BMPs: Immediate and Easy

Building Evaluation
Walk-through:
A tour of the building during different operational periods (i.e.
during business hours, after hours, during major events).

• Take note of the following:
– Lighting
– Electronic equipment
– Temperature/humidity
– Noticeable building damage
– Staff expertise and knowledge

• Pros and cons:
– Pros: self-guided, low cost, many low cost opportunities
– Cons: technical opportunities will likely be missed



No/Low Cost Practices
Lighting – No Cost

• Turn off when not in use!
• Daylight – Use sunlight when available and arrange furniture so
that sunlight does not cause glares.
• Delamping - Evaluate how much lighting individuals need to
work and remove unnecessary lamps.

U of M light switch Daylight-lit room Delamped lamp
sticker reminder


Lighting – Low Cost

• Automatic lighting controls - Use occupancy sensors,
especially in bathrooms, closets, hallways, or other occasionally
used areas.
• LEDs – Use especially in “Exit” signs and security lights that
must always be on.

Building Envelope – Low Cost

• Don’t forget your storm windows
• Seal windows and doors
• Rope caulk weatherstripping
• Door sweeps
• Caulking cracks


Computer – No cost

• Signs and reminders to do the following:
•Unplug when you leave
• Use powerstrips for easy reach
• Use sleep mode when you step away Phantom Load=

Appliances – No cost

• Put little-used appliances on powerstrips
• Down-size number of appliances

Appliances - Low(ish) cost

• When purchasing new appliances, buy EnergyStar
• Utilize low flow faucet aerators and pre-rinse spray valves to
reduce hot water use

Pre-rinse spray valve Faucet aerator
$30-40 ea. $1-5 ea.


Effective Scheduling – No cost

• Are buildings occupied during the evening, over weekends and/or
holidays?
•Check if heating and lighting are necessary
• What is the cleaning schedule like?
•Dedicate specific days to specific zones for cleaning and only heat/light
those zones


Example
Schedule:



Other behavior – no cost

• Add a delay to the elevator door to
encourage stair use

• Use automatic openers on doors only
when absolutely necessary

• Think twice before clicking the PRINT, &
use both sides of the paper

• Get rid of the nice-to-have but
unnecessary personal, energy-consuming
luxuries like fish tanks, decorative
lighting, coffee cup warmers, miniature
water falls, etc.

• Be creative!



Other behavior – No cost

1. Provide an supportive atmosphere
• Point out at meetings who has fewest
extra electronics
• Caught “Green Handed” awards/prizes
• Report on the reduction of paper/energy
2. Use norms to further your cause
• Mention that other cities and buildings
are working towards sustainability
targets

Other behavior – Resources
Everyone’s doing it.
• Community Based Social Marketing

BMPs: Longer term & more effort

Building Evaluation
• Recommissioning:

“A systematic process to improve the operation of your
building systems so that they:

• Actually meet your needs (for ventilation, comfort, air
quality control)
• Use only as much energy as is really necessary to do
so.”

Center for Energy and the Environment4



Building Evaluation
Recommissioning - So how does it work?

• “Calibration: ensure control sensors and devices are calibrated
• Scheduling and Enabling: Turn equipment off or down when unneeded
• Air and Water Flows: Don’t run equipment at higher air or water flows
than needed
• Ventilation: Make sure the right amount of ventilation air gets in, and that
it gets to where the people are.
• Setpoints and Resets: Don’t run equipment at higher heating or lower
cooling temperatures or higher air or water pressures than needed
• Condition and Function Checks: Make sure key equipment is working
the way it should (actuators, dampers, valves, VFDs, etc.)”

Center for Energy and the Environment4



Building Evaluation
Recommissioning – In-house experts

• Use talents and knowledge of current maintenance staff

• Capacity building - consider investing in building management
training courses for staff
– Practices in the building industry are constantly evolving
– Extra training helps provide and ensure proper energy
management over the long term
– Utilities might help with training costs – just ask!

es_Business/Pages/Recommissioning.aspx

• Ask your local utility about recommissioning information and
rebates



Building Evaluation
Energy audit:
• Inspection, analysis, and survey from professional engineers (PE)
and/or registered architects (RA) of building energy flows and
building “tightness”
• Provides recommendations for capital improvements
Energy audit - Resources
• Find PE/RAs in your area:
