EAP1 Fundamental Commissioning (Cx) REQ

Intent EA Prerequisite 1:

To verify that the project’s energy-related systems are installed, calibrated and perform according to the owner’s project requirements, basis of design and construction documents.


Intent EA Credit 3:

To begin the commissioning process early in the design process and execute additional activities after systems performance verification is completed.


Cx Benefits of commissioning include reduced energy use, lower operating costs, reduced contractor callbacks, better building documentation, improved occupant productivity and verification that the systems perform in accordance with the owner’s project requirements.


At a minimum Projects must Commission:


Commission Process:

• Begin EARLY in Design Process • Independent Commissioning Authority (CxA) • OPR – Owners Project Requirements • BOD – Basis of Design

EAP2 Minimum Energy Performance REQ EAC1 Optimize Energy Performance PTS

Intent

To establish the minimum level of energy efficiency for the proposed building and systems to reduce environmental and economic impacts associated with excessive energy use.


SCHOOLS

EPA's TargetFinder Rating Tool Target Finder is an online tool that can establish

energy performance goals for a project.

It uses data such as zip code and building type to calculate the estimated total energy use for the building, and then it assigns an energy performance rating on a scale of 1 to 100.

Energy Costs?

Annual energy costs are determined using rates for purchased energy, such as electricity, gas, oil, propane, steam, and chilled water, that are based on actual local utility rates or

the state average prices published annually by the U.S. Department of Energy’s Energy Information Administration, at www.eia.doe.gov.


Process Energy Office and general miscellaneous equipment Computers Elevators and escalators Kitchen cooking and refrigeration Laundry washing and drying Lighting exempt from the lighting power allowance (e.g., lighting integral to medical equipment) and other (e.g., waterfall pumps).


Regulated (non-process) Energy

Lighting

Heating, ventilating, and air conditioning (HVAC)

Service water heating for domestic or space heating purposes.


Strategies to Increase Energy Performance

Reduce demand

Harvest free energy

Increase efficiency

Recover waste energy

EAC6 Green Power

Intent To encourage the development and use of grid-source, renewable energy technologies on a net zero pollution basis.

EAC6 Green Power

NC, SCHOOLS & CS Engage in at least a 2-year renewable energy contract to provide at least 35% of the building’s electricity from renewable sources, as defined by the Center for Resource Solutions’ Green-e Energy product certification requirements.

EAC6 Green Power

All purchases of green power shall be based on the quantity of energy consumed, not the cost.

OPTION 1. Determine Baseline Electricity Use

Use the annual electricity consumption from the results of EA Credit 1: Optimize Energy Performance.

OR

OPTION 2. Estimate Baseline Electricity Use

Use the U.S. Department of Energy’s Commercial Buildings Energy Consumption Survey (CBECS) database to determine the estimated electricity use.

EAC6 Green Power

RECs Renewable energy certificates (RECs), tradable renewable certificates (TRCs), green tags and other forms of green power that comply with the technical requirements of the Green-e Energy program may be used to document compliance with this credit.
