HVAC Design ManualNovember 1, 2017FOREWORDVA Program Offices, project teams, designers and constructors, are obligated to our Nation'sVeterans and taxpayers to make the most effective and efficient use of resources, by providinga continuum of safe, secure, high quality, high performance, and high value environments ofcare and service for Veterans. The VA Office of Construction and Facilities Management (CFM)supports the Department's mission through development and application of standards as abasis for disciplined planning, design, and construction of VA facilities.VA Standards are the culmination of a partnership among the Department of Veterans Affairs(VA), the VA Administrations, Program Officials, Clinicians, Industry, Academic and ResearchOrganizations, Expert Consultants, and the Office of Construction and Facilities Management.VA Standards are developed through integration of VA-specific requirements, Federal law andregulation, benchmarking of industry best practice, evidence-based research and design, andvalue-based analysis of leading edge innovation. The result is the establishment of best valuestandards for optimum functionality, safety, operability, performance, and quality throughoutthe VA environment of care and service.The VA Technical Information Library (TIL) (www.cfm.va.gov/TIL) provides standards for all VAplanning, design, and construction projects. VA TIL Standards communicate the basis of designand are required to be utilized by project teams working on new construction and renovationsof existing facilities. VA Standards will maximize the effectiveness and efficiency of theplanning and design process and facilitate a high level of design, while controlling construction,operating, and maintenance costs.For all VA projects, it is required that project teams comply with the following in all phases ofproject development:1) All applicable VA Standards published in the VA Technical Information Library (TIL) shallbe applied as a basis, foundation, and framework in planning, design, and construction.Any substantial variance from Standards shall be considered only as required toaccommodate specific site, functional, and operational conditions. Upon considerationof variance CFM shall be consulted, and each Administration will function as AuthorityHaving Jurisdiction for decision. Each substantial variance shall have a basis rationaleand be documented in the project record;2) Clinicians, providers, primary users, and other stakeholders shall be involved in allphases of project development to best adapt Standards for specific functional,operational, and site conditions, and to provide optimum service environments forVeterans. This also includes installations and modifications of systems or technologyinvolving safety, security, functionality, or environmental quality. Stakeholderinvolvement shall be documented in the project record.VA TIL Standards are not project‐specific. It is impossible to foresee all rapidly evolvingrequirements of VA facilities and each site or project will have unique requirements orconditions. Site‐specific issues must be addressed within the context of these standards andapplied to each individual project. Use these Standards does not preclude the need for, norabsolve planners, designers, and constructors of their responsibility to provide complete,GENERALiv

HVAC Design ManualNovember 1, 2017INTRODUCTIONThis 2017 VA HVAC Design Manual for the Department of Veterans Affairs (VA) HealthcareFacilities is the only detailed design requirements manual for VA. Compliance to The DesignManual, which promulgates minimum performance design standards for VA owned and leasednew buildings and renovated facilities, ensures that VA facilities will be of the highest quality tosupport Veterans Health Care.The Office of Construction and Facilities Management (CFM) is responsible for developing andmaintaining this Design Manual. Revisions are made as necessary. The Architect/Engineers(A/E), Project Managers (PM), Resident Engineers (RE), Contractors, and Consultants shouldrefer to the VA Directives, VA Policies, VA Design Alerts and Memorandums before each use ofthis design manual to note any updates that have been made since the last use. The VA DesignManuals align the VA Facilities program with the VA mission.VA has adopted the latest edition of the codes and standards as a minimum for all projectsperformed in the modernization, alteration, addition, or improvement of its real property andthe construction of new structures. VA design Manuals and Master Specifications specifyadditional codes and standards that VA follows on its projects.Design, construction, renovation and installation of all VA Facilities must be in accordance withthis Design Manual and with the latest editions and/or revisions of all applicable codes, policiesand standards. Nothing in this Design Manual should be construed as authorization orpermission to disregard or violate local and legal requirements.Substantial variance from this Design Manual may be proposed to promote new concepts anddesign enhancements. Variance shall not conflict with Federal Regulations, Public Laws,Executive Orders, or the needs of the end users. Substantial variance shall be reviewed by theVHA Office of Capital Asset Management, Engineering and Support (OCAMES) in consultationwith CFM Consulting Support Service (CSS).Any reviewed variances are subject to written approval by the VA Authority. The VA Authorityfor all VHA projects is the Director of the Office of Capital Asset Management, Engineering andSupport (OCAMES). The VA Authority for VBA and NCA projects is the Director of the Office ofConstruction and Facilities Management (CFM). Request for variance shall be submitted inwriting by the A/E through the COR in sufficient detail to explain the issues.GENERALviii

As they got smaller, they would get hotter and .
