4.6 EA CREDIT 3: ENHANCED

COMMISSIONING - 2 POINTS

4.6.1 INTENT:

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

4.6.2 REQUIREMENTS:

Implement, or have a contract in place to implement, the following additional commissioning process activities in addition to the requirements of EA Prerequisite 1:

Fundamental Commissioning of Building

Energy Systems and in accordance with the

LEED Reference Guide for Green Building

Design and Construction, 2009 Edition:

- Prior to the start of the construction documents phase, designate an independent commissioning authority (CxA) to lead, review and oversee the completion of all commissioning process activities.

- The CxA must have documented commissioning authority experience in at least 2 building projects.

- The individual serving as the CxA:

- Must be independent of the work of design and construction.

- Must not be an employee of the design firm, though he or she may be contracted through them.

- Must not be an employee of, or contracted through, a contractor or construction manager holding construction contracts.

- May be a qualified employee or consultant of the owner.

- The CxA must report results, findings and recommendations directly to the owner.

- The CxA must conduct, at a minimum, 1 commissioning design review of the owner’s project requirements basis of design, and design documents prior to the mid-construction documents phase and back-check the review comments in the subsequent design submission.

- The CxA must review contractor submittals applicable to systems being commissioned for compliance with the owner’s project requirements and basis of design. This review must be concurrent with the review of the architect or engineer of record and submitted to the design team and the owner.

- The CxA or other project team members must develop a systems manual that gives future operating staff the information needed to understand and optimally operate the commissioned systems.

- The CxA or other project team members must verify that the requirements for training operating personnel and building occupants have been completed.

- The CxA must be involved in reviewing the operation of the building with operations and maintenance (O&M) staff and occupants within 10 months after substantial completion. A plan for resolving outstanding commissioning-related issues must be included.

4.6.3 POTENTIAL TECHNOLOGIES &

STRATEGIES:

Although it is preferable that the CxA be contracted by the owner, for the enhanced commissioning credit the CxA may also be contracted through the design firms or construction management firms not holding construction contracts.

The LEED Reference Guide for Green Building

Design and Construction, 2009 Edition provides detailed guidance on the rigor expected for the following process activities:

- Commissioning design review

- Commissioning submittal review

- Systems manual.

4.7 EA CREDIT 4: ENHANCED REFRIGERANT

MANAGEMENT - 2 POINTS

4.7.1 INTENT:

To reduce ozone depletion and support early compliance with the Montreal Protocol while minimizing direct contributions to climate change.

4.7.2 REQUIREMENTS:

OPTION 1

Do not use refrigerants.

OPTION 2

Select refrigerants and heating, ventilation, air conditioning and refrigeration (HVAC&R) equipment that minimize or eliminate the emission of compounds that contribute to ozone depletion and climate change. The base building HVAC&R equipment must comply with the following formula, which sets a maximum threshold for the combined contributions to ozone depletion and global warming potential:

LCGWP ≤ 13

LCGWP = [GWPr x (Lr x Life +Mr) x Rc]/Life

LCGWP: Lifecycle Direct Global Warming

Potential [kg CO2/ (kW/ycar)]

For multiple types of equipment, a weighted average of all base building HVAC&R equipment must be calculated using the following formula:

( LCGWP) x Qunit <=13

Qtotal

Qunit = Gross eurovent rated cooling capacity of an individual HVAC or refrigeration unit

(kW)

Qtotal = Total gross eurovent rated cooling capacity of all HVAC or refrigeration

Small HVAC units (defined as containing less than 0.5 pounds of refrigerant) and other equipment, such as standard refrigerators, small water coolers and any other cooling equipment that contains less than 0.5 pounds of refrigerant, are not considered part of the base building system and are not subject to the requirements of this credit.

Do not operate or install fire suppression systems that contain ozone-depleting substances such as CFCs, hydrochlorofluorocarbons (HCFCs) or halons.

4.7.3 POTENTIAL TECHNOLOGIES &

STRATEGIES:

Design and operate the facility without mechanical cooling and refrigeration equipment. Where mechanical cooling is used, utilize base building HVAC&R systems for the refrigeration cycle that minimize direct impact on ozone depletion and global climate change. Select HVAC&R equipment with reduced refrigerant charge and increased equipment life. Maintain equipment to prevent leakage of refrigerant to the atmosphere. Use fire suppression systems that do not contain HCFCs or halons.

4.8 EA CREDIT 5: MEASUREMENT AND

VERIFICATION - 3 POINTS

4.8.1 INTENT:

To provide for the ongoing accountability of building energy consumption over time.

4.8.2 REQUIREMENTS:

OPTION 1

Develop and implement a measurement and verification (M&V) plan consistent with

Option D: Calibrated Simulation (Savings

Estimation Method 2) as specified in the

International Performance Measurement &

Verification Protocol (IPMVP) Volume III:

Concepts and Options for Determining

Energy Savings in New Construction, April

2003.

The M&V period must cover at least 1 year of post-construction occupancy.

Provide a process for corrective action if the results of the M&V plan indicate that energy savings are not being achieved.

OPTION 2

Develop and implement a measurement and verification (M&V) plan consistent with

Option B: Energy Conservation Measure

Isolation, as specified in the International

Performance Measurement & Verification

Protocol (IPMVP) Volume III: Concepts and

Options for Determining Energy Savings in

New Construction, April 2003.

The M&V period must cover at least 1 year of post-construction occupancy.

Provide a process for corrective action if the results of the M&V plan indicate that energy savings are not being achieved.

4.8.3 POTENTIAL TECHNOLOGIES &

STRATEGIES:

Develop an M&V plan to evaluate building and/or energy system performance.

Characterize the building and/or energy systems through energy simulation or engineering analysis. Install the necessary metering equipment to measure energy use.

Track performance by comparing predicted performance to actual performance, broken down by component or system as appropriate.

Evaluate energy efficiency by comparing actual performance to baseline performance.

While the IPMVP describes specific actions for verifying savings associated with energy conservation measures (ECMs) and strategies, this LEED credit expands upon typical IPMVP

M&V objectives.

Measurement & verification activities should not necessarily be confined to energy systems where ECMs or energy conservation strategies have been implemented.

The IPMVP provides guidance on M&V strategies and their appropriate applications for various situations.

These strategies should be used in conjunction with monitoring and trend logging of significant energy systems to provide for the ongoing accountability of building energy performance.

For the corrective action process, consider installing diagnostics within the control system to alert the staff when equipment is not being optimally operated.

Conditions that might warrant alarms to alert staff could include:

- Leaking valves in the cooling and heating coils within air handling units;

- Missed economizer opportunities (e.g., faulty economizer damper controls) ;

- Software and manual overrides allowing equipment to operate 24 hours a day/7 days a week;

- Equipment operation during unusual circumstances (e.g., boiler on when outside air temperature is above 65 °F).

Construction debris processed into a recycled content commodity that has an open market value (e.g., wood derived fuel [WDF], alternative daily cover material, etc.) may be applied to the construction waste calculation.

Designate a specific area(s) on the construction site for segregated or comingled collection of recyclable materials, and track recycling efforts throughout the construction process. Identify construction haulers and recyclers to handle the designated materials.
