Building Commissioning is rapidly being embraced by public and private organizations because of its benefits to the building envelope and improved project delivery results. 

If commissioning is part of your process, expert guidance is essential.

ASHRAE offers several resources to help guide your team through this critical phase of a new construction project.


Commissioning Stakeholder's GuideCommissioning Stakeholders' Guide

Using ASHRAE Guideline 0 and ANSI/ASHRAE/IES Standard 202, this guide provides concise advice, instruction, and step-by-step requirements for new construction commissioning for owners, designers, and project managers. Purchasers also receive access to download more than 50 customizable checklists for use in the field.

The Strategic Guide to Commissioning FREE
This guide, a report from the ASHRAE Presidential Ad-Hoc Committee, Building Performance Alliance on Commissioning, serves as a quality-focused, high level strategic commissioning resource, providing stakeholders with a basis for understanding enhanced delivery of new and existing building projects. It describes the value, benefits, and rationale for verifying and documenting that all commissioned systems and assemblies are planned, designed, installed, tested, operated, and maintained to meet the Owner's Project Requirements (OPR) for new buildings and/or major renovations, and the Current Facility Requirements (CFR) for existing buildings. This guide is also available in Spanish.

Standard 202-2024 -- The Commissioning Process Requirements for New Buildings and New Systems

ASHRAE/IES Standard 202 describes the Commissioning Process for new buildings and new systems, the roles of the principal agents and stakeholders, and a framework for developing design documents, specifications, procedures, documentation, and reports. It also describes the general requirements for a training program for continued successful system and assembly performance.



Standard 230-2022, Commissioning Process for Existing Buildings and Systems

ASHRAE Standard 230 establishes the minimum requirements for commissioning an existing building and allows the Owner to define the specific scope of work and project budget. This standard provides procedures, methods, and documentation requirements for each commissioning activity from planning through initial ongoing commissioning.



Guideline 0-2019 -- The Commissioning Process

This Guideline, also available in Spanish, describes the Commissioning Process capable of verifying that a facility and its systems meet the Owner's Project Requirements. The procedures, methods, and documentation requirements in this guideline describe each phase of the project delivery and the associated Commissioning Processes from pre-design through occupancy and operation.



Guideline 0.2-2015 -- Commissioning Process for Existing Systems and Assemblies

This Guideline is the comprehensive description of a systematic quality-oriented process that improves the performance and sustainability of existing facilities. This road map includes planning, assessing, investigating, implementing, verifying, and documenting performance to meet defined and optimized operational requirements.



Guideline 1.1-2007 -- HVAC&R Technical Requirements for The Commissioning Process

Guideline 1.1-2007 focuses on HVAC&R systems while addressing total building commissioning processes by validating interfaces and possible interferences between all building systems. 



Guideline 1.2-2019 -- Technical Requirements for the Commissioning Process for Existing HVAC&R Systems and Assemblies

Never-before-published Guideline 1.2-2019 offers brand new content outlining requirements for the application of the Commissioning Process (Cx) described in ASHRAE Guideline 0.2 to existing heating, ventilating, air-conditioning, and refrigerating (HVAC&R) systems and assemblies. 



Guideline 1.3-2018 -- Building Operations and Maintenance Training for the HVAC&R Commissioning Process

Guideline 1.3, also available in Spanish, provides methodologiesand formats for developing training plans, conducting training programs, anddocumenting training results for the operation and maintenance of building HVAC&R systems during the Commissioning (Cx) Process.



Guideline 1.4-2019 -- Preparing Systems Manuals for Facilities

ASHRAE Guideline 1.4 provides guidance and procedures for producing a Systems Manual. The format and content of the Systems Manual provided in this guideline can be effectively used in both new construction and for an existing building, even if the building is not commissioned.



Guideline 1.5-2017 -- The Commissioning Process for Smoke Control Systems

Guideline 1.5 describes the technical requirements for the application of the Commissioning Process described in ASHRAE Guideline 0 that will verify that the smoke control system achieves the Owner's Project Requirements (OPR).



Guideline 4-2019, Preparation of Operating and Maintenance Documentation for HVAC&R Systems

ASHRAE Guideline 4 provides guidance for the preparation and delivery of operations and maintenance (O&M) documentation that is simple to update, delivered on time, easy to use, and provides accurate and relevant information. This guideline is intended for use by those responsible for the design, manufacturing, construction, commissioning, and operation of building HVAC&R and on-site generation systems.



Guideline 41-2023, Design, Installation , and Commissioning of Variable Refrigerant Flow (VRF) Systems

ASHRAE Guideline 41 expands on the basic information provided in ASHRAE Handbook—HVAC Systems and Equipment to provide a procedure for the design, installation, and commissioning of variable refrigerant flow (VRF) systems.


Commissioning Definitions and Terminology for the Building Industry: A Common Overview

Commissioning Definitions and Terminology for the Building Industry: A Common Overview is a joint effort between ASHRAE, AiCAAR and CIBSE to standardize terminology related to commissioning. This resource is an important step in improving building performance through improved communication and consistent, globalized terminology to improve collaboration among building technology professionals.
