ENERGY BENCHMARKING

22 of 53

Reasons for benchmarking

ENERGY BENCHMARKING

Your best first step! You can’t find the path to your intended goal or destination unless you know where you are!
Allow building owners to grade their energy performance
The benchmark “score” identifies whether opportunities exist
Once you identify projects and implement them, you can track your savings and your updated benchmarked score

23 of 53

What is benchmarking?

ENERGY BENCHMARKING

Establishes a metric for measuring performance

What does 185 kbtu/sf mean to a building owner?

Compares the performance to a standard or to comparable buildings
Primary building energy benchmarking tool is ENERGY STAR Portfolio Manager – ratings based on CBECS 2012

Commercial Buildings Energy Consumption Survey

24 of 53

ENERGY STAR Portfolio Manager

ENERGY BENCHMARKING

A free tool that benchmarks your building against a database of similar buildings

Required by law in Philadelphia, and many other cities
Some have voluntary programs

Corrects for occupancy (hours and number of people) weather, computers, square footage and type of use, among other elements
Provides a sore of 1 – 100 and a “Statement of Energy Performance” (SEP) as a benchmark report

DETAILED ENERGY AUDITS

29 of 53

How do buildings work?

DETAILED ENERGY AUDITS

Multiple systems use energy
There are interactive effects and weather impacts
Identify the primary energy-using systems, breakdown by percent

HVAC
Lighting
Domestic hot water
Plug loads: appliances, computers, printers, copier, space heaters(!!)
Building envelope (impact on HVAC and lighting)

Roof, walls, doors, windows

Server rooms

30 of 53

Energy Audits

DETAILED ENERGY AUDITS

Where, when and how are you using energy?
Have an expert evaluate your building to identify projects that will improve building energy performance

Perform operational studies to identify ways to save energy quickly, with little or no investment
Inventory of primary energy using equipment
Evaluate existing equipment based on age, condition, efficiency, size
Energy modeling (investment grade audit) for major capital investments
Assess energy savings and financial returns

31 of 53

Energy Audits and Energy Planning

DETAILED ENERGY AUDITS

Energy Audits can be the foundation of an Energy Master Plan for future facility improvements

Identify your goals, ie. 25% reduction in energy use, 100% renewable
Implement capital upgrades to buildings to reach goals
Plan for equipment replacement at end of life

Can establish a baseline for tracking your future energy performance and metrics to measure your success

32 of 53

Utility Bill Analysis

DETAILED ENERGY AUDITS

Rate structure
Consumption quantities
Natural gas savings versus electricity (BTUs)
Consumption patterns
Projection or baseline of future energy consumption

Operational Improvements

DETAILED ENERGY AUDITS

Low cost, high return on investment options:

Control sequences to match building operation to occupancy
Setpoints and efficient management of systems
Occupant behavior
Maintenance staff involvement
Best suited to facilities with limited operating hours

ENERGY MANAGEMENT POLICIES

38 of 53

What does an Energy Management Policy do?

ENERGY MANAGEMENT POLICIES

Provides guidance or requirements for operational and capital purchase activities, such as:

Assigns responsibility for energy performance of buildings
Outlines target settings for HVAC equipment to optimize energy performance, comfort, productivity and indoor air quality
Sets purchasing policies for appliances and other plug loads
Can also identify beyond code priorities for new buildings and major renovations such as:

LEED
Green Globes
ENERGY STAR

Provides guidance for occupant behaviors that impact energy use
Training requirements for maintenance staff

STRATEGIC PLANNING AND CAPITAL UPGRADES

Capital Investments

STRATEGIC PLANNING AND CAPITAL UPGRADES

Lighting

LED
Controls

Building Envelope

Insulation
Windows
Infiltration

Heating and Air Conditioning

More efficient primary systems (consider electrification)
Better controls
Accessories:

Economizers
Heat Recovery
VFDs
Demand Controlled Ventilation

Domestic Hot Water

41 of 53

Heating and Air Conditioning

STRATEGIC PLANNING AND CAPITAL UPGRADES

Heating, Ventilating and Air Conditioning (HVAC) accounts for 40 – 60% of the energy used in U.S. commercial buildings
The older your current system is the greater the opportunity to improve efficiency
New controls
Proper sizing and set up (lighting and building envelope affect this)
Electrification

42 of 53

Best HVAC Opportunities

New construction vs. existing buildings
End of life replacements

Be prepared 1 to 5 years before system reaches the end of its useful life – energy audit, schematic design
Don’t just rely on your maintenance contractor to do the best thing for your needs
Calculating paybacks for end of life
Efficiency in HVAC

Can you do better than 100% efficiency?

43 of 53

Best HVAC Opportunities

The Case for Investing in Electrification

Our primary options for renewable energy all involve electricity
Investing in natural gas or oil fired heating prevents getting to zero carbon emissions for the life of the equipment purchased.
Our ONLY option for getting to net zero carbon emissions is to use electricity for all heating and cooling

44 of 53

Best HVAC Opportunities

Heating Efficiency examples

Oil fired heat – 80% (0.80 COP)
Standard natural gas boiler - 85%
Modular natural gas condensing boiler – 95% - 98%
Air source heat pump – COP > 2.0 (200%!)
Geothermal/Ground Source heat pump - COP 3 - 4

Cooling Efficiency

Air-cooled DX – COP of 2.8
Air source heat pump – COP of 3 - 5
Water cooled centrifugal chiller – COP > 5.5
Geothermal – COP up to 18! (vs. 2.8 for DX)
