EA Credit 5: Measurement and Verification
3 Points

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

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.
OR
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.
OR
OPTION 3 (1 point)
Meet MPR 6 through compliance Opttion1: Energy and Water Data Release Form. Projects must register an
account in ENERGY STAR’s Portfolio Manager tool and share the project file with the USGBC master account.

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).
Besides control diagnostics, consider employing retro-commissioning services or dedicating staff to investigate
increases in energy usage (such a staff member is usually a resource conservation manager — see http://www.energy.state.or.us/rcm/rcmhm.htm for additional information).

EA C5: 计量与验证(M&V)
3分

目的
提供建筑能源消耗随时计量能力。
要求
选项1
根据2003年4月版的国际效能计量与验证协议(IPMVP)第三册：新建筑确定节能的定义与方
法中，方法D:模拟校准(节能估算法2)，制定并实施一个计量和验证(M&V)方案。
M&V应在建筑使用后实施至少一年时间。
如M&V实施中发现节能未达目标，提供整改的活动和结果。
或者
选项2
根据2003年4月版的国际效能计量与验证协议(IPMVP)第三册：新建筑确定节能的定义与方
法中，方法B:能源节约隔离测量，制定并实施一个计量和验证(M&V)方案。
M&V应在建筑使用后实施至少一年时间。
如M&V实施中发现节能未达目标，提供整改的活动和结果。

技术措施和策略
制定一个M&V方案来评价建筑，和/或能源系统效能，通过模拟或分析说明建筑或能源系统。安
装必要的能源计量设备，合理分解各用能部分，对比分析预期能效和实际用能情况。评价基准
能效和实际能效的对比。
IPMVP给出了验证节能措施(ECM)的特定活动和方法，本LEED项目则是在IPMVP的M&V目标基础上
的延伸。有些实施节能措施的能源系统由于条件限制，也不必非得进行计量与验证。IPMVP只是
对各种情形给出了计量与验证的适用方法。这些方法应结合能源数据采集，提供随时的用能监
控。
对于整改活动，可考虑在控制系统中安装诊断系统，在设备没有最佳运行时提示操作人员。这
些提示或报警应包括：
-- 空气处理装置中阀门出现冷热泄漏；
-- 节能器失效(例如，节能器阀门控制失效) ;
-- 软件或手动使得设备超时运行，如每周7天24小运转；
-- 设备在异常环境条件下运转（如在室外温度超过65°F时启动锅炉）
除控制系统诊断外，考虑采用再调试或经验员工发现用能增加原因。（这种员工通常是节能主
管，其它信息见http://www.energy.state.or.us/rcm/rcmhm.htm )。
