EA Prerequisite 1: Fundamental Commissioning of Building Energy Systems
Required

Intent
To verify that the project’s energy-related systems are installed, and calibrated to perform according to the owner’s
project requirements, basis of design and construction documents.
Benefits of commissioning include reduced energy use, lower operating costs, fewer contractor callbacks, better
building documentation, improved occupant productivity and verification that the systems perform in accordance
with the owner’s project requirements.

Requirements
The following commissioning process activities must be completed by the project team:
-- Designate an individual as the commissioning authority (CxA) to lead, review and oversee the completion of
the 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 project design and construction
management, though the CxA may be an employee of any firm providing those services. The CxA may be a
qualified employee or consultant of the owner.
• The CxA must report results, findings and recommendations directly to the owner.
• For projects smaller than 50,000 gross square feet, the CxA may be a qualified person on the design or
construction team who has the required experience.
-- The owner must document the owner’s project requirements. The design team must develop the basis of
design. The CxA must review these documents for clarity and completeness. The owner and design team must be responsible for updates to their respective documents.
-- Develop and incorporate commissioning requirements into the construction documents.
-- Develop and implement a commissioning plan.
-- Verify the installation and performance of the systems to be commissioned.
-- Complete a summary commissioning report.
Commissioned Systems
Commissioning process activities must be completed for the following energy-related systems, at a minimum:
-- Heating, ventilating, air conditioning and refrigeration (HVAC&R) systems (mechanical and passive) and
associated controls
-- Lighting and daylighting controls
-- Domestic hot water systems
-- Renewable energy systems (e.g., wind, solar)

Potential Technologies & Strategies
Engage a CxA as early as possible in the design process. Determine the owner’s project requirements, develop and maintain a commissioning plan for use during design and construction and incorporate commissioning requirements in bid documents. Assemble the commissioning team, and prior to occupancy verify the performance of energy consuming systems. Complete the commissioning reports with recommendations prior to accepting the commissioned systems.
Owners are encouraged to seek out qualified individuals to lead the commissioning process. Qualified individuals are identified as those who possess a high level of experience in the following areas:
-- Energy systems design, installation and operation
-- Commissioning planning and process management
-- Hands-on field experience with energy systems performance, interaction, start-up, balancing, testing,
troubleshooting, operation and maintenance procedures
-- Energy systems automation control knowledge
Owners are encouraged to consider including water-using systems, building envelope systems, and other systems in the scope of the commissioning plan as appropriate. The building envelope is an important component of a facility that impacts energy consumption, occupant comfort and indoor air quality. While this prerequisite does not require building envelope commissioning, an owner can achieve significant financial savings and reduce risk of poor indoor air quality by including it in the commissioning process.
The LEED Reference Guide for Green Building Design and Construction, 2009 Edition provides guidance on the rigor expected for this prerequisite for the following:
-- Owner’s project requirements
-- Basis of design
-- Commissioning plan
-- Commissioning specification
-- Performance verification documentation
-- Commissioning report

EAP1: 建筑能源系统基本运行调试
必须

目的
确认工程的能源系统已安装、校核，并能够按照工程业主要求、工程设计、建设文件运行。
运行调试的好处在于可降低能源使用、节省运行费用、减少工程返工、便于建筑建档，可促进
建筑员工的生产效率，确认建筑运行符合业主对于工程的要求。

要求
下述运行调试工作，必须在本阶段实施和完成：
-- 指派一个独立机构作为运行调试单位(CxA)，来领导、评审、监管、验收运行调试工作.
-- 该CxA必须书面说明具有至少具有2个工程的运行调试经验。
-- 作为运行调试机构，必须独立于设计、施工管理，但其成员可以是设计、施工的员工。
运行调试机构可以是业主的资深员工或顾问。
-- 运行调试机构必须可以向业主直接报告结果、发现和建议。
-- 小于建筑面积50,000平方英尺的工程，运行调试机构可以是一个有相关经验的设计、施
工人员。
-- 业主必须提供业主的工程要求文件，设计部门必须提供设计依据和基础文件。运行调试机
构必须评审这些文件，确认其完备性。业主和设计部门必须负责各自的变更。
-- 将运行运行调试工作编入施工文件中。
-- 编制并实施运行调试方案。
-- 对要进行运行调试的系统性能的安装、性能进行检查确认。
-- 提出运行调试报告简述。

需要运行调试的系统
运行调试活动必须至少覆盖以下能源相关系统：
-- 采暖、通风、空调和制冷系统，以及相关控制系统；
-- 照明和采光控制系统；
-- 热水系统；
-- 可再生能源系统（如风能、太阳能）；

技术措施和策略
尽早的在设计阶段，引入运行调试机构。确定业主的工程要求，编制并维护一个运行调试方案，
用于设计和施工，并将运行调试要求招标文件中。组建一个运行调试团队，在工程入住前检查
确认系统性能，在系统验收前，提出运行调试报告。
鼓励业主寻找一个资深人员领导运行调试工作，所谓资深人员应在以下领域富有高水平经验：
-- 能源系统设计、安装和运行；
-- 运行调试策划和过程管理；
-- 对于能源系统性能检查、启动、权衡、测试、故障判断、系统运行和维护程序富有现场经
验；
-- 能源系统自动控制知识；
鼓励业主适当地将用水系统、建筑围护结构和其它系统纳入运行调试工作中，围护结构是影响
建筑能源消耗、室内热舒适度和室内空气质量的重要因素，虽然基本运行调试并没有要求涵盖
建筑围护结构，但将它纳入运行调试工作，可为业主带来较多的节省投资、并减少室内空气质
量问题的风险。

LEED参考手册2009版，对于以下概念提出了严格的要求：
-- 业主的工程要求；
-- 设计依据和基础；
-- 调试运行方案；
-- 运行调试规范；
-- 性能检查文件；
-- 运行调试报告；
