- CONTENTS
- FOREWORD
- 1. PURPOSE [Go to Page]
- 1.1 The purpose of this guideline is to provide requirements for the application of the Commissioning (Cx) Process described in ASHRAE Guideline 0.2 to existing heating, ventilating, air-conditioning, and refrigerating (HVAC&R) systems and assemblies.
- 2. SCOPE [Go to Page]
- 2.1 This guideline applies to the procedures, methods, and documentation requirements for each phase of the Commissioning (Cx) Process applied to existing HVAC&R systems and assemblies, including:
- 2.2 This guideline focuses on the following:
- 3. DEFINITIONS AND ABBREVIATIONS [Go to Page]
- 3.1 Definitions
- 3.2 Initialisms and Acronyms
- 4. PROCESS OVERVIEW [Go to Page]
- 4.1 Refer to ASHRAE Guideline 0.2 for process overview.
- 4.2 The EBCx Process is highly cost effective for improving existing HVAC&R systems. Experience shows many projects pay for themselves in one to three years. The total cost to the Owner of the EBCx project consists of several factors: the Commissioni...
- 4.3 The Hand-Off Phase budget is based on the complexity of the facility and the current state of the Ongoing Commissioning (OCx) Plan, the Facility Guide, and the Systems Manual. Because these factors can be assessed at the outset of the project, th...
- 4.4 The OCx operational budget should be included within the facility operating budget, subject to the current and future state of facility maintenance. Any additional costs will be associated with the increased data collection and reporting required...
