EAc5 — ENHANCED COMMISSIONING
增强调试

CREDIT New Construction 1–4分 / Core and Shell 1–3分

影响领域：✓ Decarbonization

INTENT 意图

To further support the design, construction, and eventual operation of a project that meets the owner's project requirements for energy, water, thermal comfort, indoor air quality, and durability.

进一步支持项目的设计、施工和最终运营满足业主对能源、用水、热舒适、室内空气质量和耐久性的项目要求。

REQUIREMENTS: NEW CONSTRUCTION (1–4 pts)

选拔路径组合最多可得4分。Platinum项目要求至少2分。

PATH 1 Enhanced Commissioning—Energy and Water Systems (1 point)
增强调试—能源与用水系统（1分）

Design Phase 设计阶段

• CxP must have commissioning experience on at least two buildings of equivalent size and complexity, and shall not be a member of the design team (unless CxP is an employee of the owner). The commissioning authority shall not be responsible for the design concept or criteria.
• Review designer's BOD for completeness, clarity, and coordination relative to OPR.
• Develop commissioning specifications and commissioning plan.
• Review submittals for commissioned systems for compliance with OPR and BOD.
• Develop and implement the systems manual for building operations staff.
• Review operator and occupant training requirements.

Construction & Occupancy Phase 施工与入住阶段

• Verify contractor's TAB plan and review TAB report.
• Verify installation and functional performance of commissioned systems.
• Perform a seasonal testing on a minimum of 10% of terminal heating and cooling units (minimum 2).
• Within 10 months after occupancy, review building operation relative to OPR. Include a plan for resolving outstanding issues.
• Develop an ongoing commissioning plan and hold an integrated systems test.

PATH 2 Enclosure Commissioning (1–3 points)
围护结构调试（1–3分）

Case 1. Enclosure Commissioning (1 point)

• Include envelope in commissioning scope per ASHRAE Guideline 0 and NIBS Guideline 3.
• Review OPR and BOD for building enclosure elements.
• Review submittals for continuity of air, water, thermal, and vapor control, and penetrations.
• Site observation at 25%, 50%, and 90% completion of exterior skin with narrative report at each observation. Include witnessing whole-building airtightness testing.
• Document results in final commissioning report.

Case 2. Enclosure + Air Leakage Testing (2 points)

• Case 1 items AND verified air leakage ≤ 0.13 cfm/sq. ft. at 50 Pa per ASTM E779/E1827.

Case 3. Enclosure + Enhanced Air Tightness (3 points)

• Case 2 items AND verified air leakage ≤ 0.08 cfm/sq. ft. at 50 Pa.

PATH 3 Monitoring-Based Commissioning (2 points)
基于监测的调试（2分）

• Develop Monitoring-Based Procedures (MBP) including energy and water performance indicators measured 15-min intervals.
• Develop plan for periodic review and incorporate results into ongoing commissioning.
• Fault detection and diagnostics for non-packaged unitary equipment with >75 MBH (22 kW) cooling or >250 MBH (73 kW) heating.
• Continuous monitoring point data trended and archived. Reports generated to demonstrate ongoing energy and water performance.
• MBP must be implemented for at least 1 year post occupancy.

CORE AND SHELL (1–3 pts) / 核心与外壳（1–3分）

Note: Enclosure pathways only available for Shell component. Path 1 (Energy + Water systems) not applicable to C&S.
