OPERATIONS AND ADMINISTRATION

LESSOR TO WORK WITH FACILITY SECURITY COMMITTEE (FSC) (SHELL)

The Lessor shall cooperate and work with the buildings Facility Security Committee (FSC) throughout the term of the lease.

ACCESS TO BUILDING INFORMATION (SHELL)

Building Information—including mechanical, electrical, vertical transport, fire and life safety, security system plans and schematics, computer automation systems, and emergency operations procedures—shall be strictly controlled. Such information shall be released to authorized personnel only, approved by the Government, by the development of an access list and controlled copy numbering. The Contracting Officer may direct that the names and locations of -Government tenants not be disclosed in any publicly accessed document or record. If that is the case, the Government may request that such information not be posted in the building directory.

Lessor shall have emergency plans and associated documents readily available in the event of an emergency.

CYBERSECURITY (SHELL)

A. Lessors are prohibited from connecting any portion of their building and access control systems (BACS) to any federally-owned or operated IT network. BACS include systems providing fire and life safety control, physical access control, building power and energy control, electronic surveillance, and automated HVAC, elevator, or building monitoring and control services (including IP addressable devices, application servers, or network switches).

B. In the event of a cybersecurity incident related to BACS, the Lessor shall initially assess the cyber incident, identify the impacts and risks to the Building and its occupants, and follow their organization’s cyber and IT procedures and protocols related to containing and handling a cybersecurity incident. In addition, the Lessor shall immediately inform the Lease Contracting Officer’s (LCO’s) designated representative, i.e., the Lease Administration Manager (LAM), about cybersecurity incidents that impact a federal tenant’s safety, security, or proper functioning.

C. Lessors are encouraged to put into place the following cyber protection measures in order to safeguard facilities and occupants:

1. Engineer and install BACS to comply with the Department of Homeland Security Industrial Control Systems Computer Emergency Response Team (DHS ICS-CERT) cyber security guidance and recommendations (https://ics-cert.us-cert.gov/Recommended-Practices).

2. Refer to the National Institute of Standards and Technology Cyber Security Framework (NISTCSF) (https://www.nist.gov/cyberframework) and cybersecurity guidance in the DHS Commercial Facilities Sector-Specific Plan (https://www.dhs.gov/publication/nipp-sspcommercial-facilities-2015) for best practices to manage cyber risks.

3. Encourage vendors of BACS to secure these devices and software through the following:

a. Develop and Institute a proper Configuration Management Plan for the BACS devices and applications, so that the system can be supported.

b. Safeguard sensitive data and/or login credentials through the use of strong encryption on devices and applications. This means using NIST- approved encryption algorithms, secure protocols (i.e., Transport Layer Security (TLS) 1.1, TLS 1.2, TLS 1.3) and Federal Information Processing Standard (FIPS) 140-2 validated modules.

c. Disable unnecessary services in order to protect the system from unnecessary access and a potential exposure point by a malicious attacker. Examples include File Transfer ProtocolFTP (a protocol used for transferring files to a remote location) and Telnet (allowing a user to issue commands remotely). Additionally, use of protocols that transmit data in the clear (such as default ZigBee) should be avoided, in favor of protocols that are encrypted.

d. Close unnecessary open ports to secure against unprivileged access.

e. Monitor and free web applications and supporting servers of common vulnerabilities in web applications, such as those identified by the (Open Web Application Security Project (OWASP) Top 10 Project (https://www.owasp.org/index.php/Category:OWASP_Top_Ten_Project).

f. Enforce Least Privilege, where proper permissions are enforced on a device or application so that a malicious attacker cannot gain access to all data. Enforcing Least Privilege will only allow users to access data they are allowed to see. Additional information can be found at https://www.beyondtrust.com/blog/what-is-least-privilege/

g. Protect against Insufficient User Access Auditing, where device or application does not have a mechanism to log/track activity by user. Enforce changing of factory default Username and Password to prevent unauthorized entry into the BACS system.

h. Use updated antivirus software subscription at all times. Kaspersky-branded products or services, prohibited from use by the Federal Government, are not to be utilized.

i. Conduct antivirus and spyware scans on a regular basis. Patching for workstations and server Operating System (OS), as well as vulnerability patching should follow standard industry best practices for software development life cycle (SDLC).

j. Discontinue the use of end of life (EOL) systems and use only applications/systems that are supported by the manufacturer.

k. Operating Systems must be supported by the vendor for security updates (e.g., do not use Windows Server 2003).

l. Proposed standard installation, operation, maintenance, updates, and/or patching of software shall not alter the configuration settings from the approved United States Government Configuration Baseline (USGCB) or tenant agency guidance (if applicable).

m. Disallow the use of commercially-provided circuits to manage building systems and install building systems on a protected network, safeguarded by the enterprise firewalls in place.

Workstations or servers running building monitor and control systems are not connected and visible on the public internet.

n. Systems should have proper system configuration hardening and align with Center for Internet Security (CIS) benchmarks or other industry recognized benchmarks. Additional information can be found at https://www.cisecurity.org/cis-benchmarks/.

FOREWORD

VA Program Offices, project teams, designers and constructors, are obligated to our Nation's Veterans and taxpayers to make the most effective and efficient use of resources, by providing a continuum of safe, secure, high quality, high performance, and high value environments of care 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 a basis 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 Research Organizations, Expert Consultants, and the Office of Construction and Facilities Management.

VA Standards are developed through integration of VA-specific requirements, Federal law and regulation, benchmarking of industry best practice, evidence-based research and design, and value-based analysis of leading edge innovation. The result is the establishment of best value standards for optimum functionality, safety, operability, performance, and quality throughout the VA environment of care and service.

The VA Technical Information Library (TIL) (www.cfm.va.gov/TIL) provides standards for all VA planning, design, and construction projects. VA TIL Standards communicate the basis of design and are required to be utilized by project teams working on new construction and renovations of existing facilities. VA Standards will maximize the effectiveness and efficiency of the planning 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 of project development:

1) All applicable VA Standards published in the VA Technical Information Library (TIL) shall be applied as a basis, foundation, and framework in planning, design, and construction.

Any substantial variance from Standards shall be considered only as required to accommodate specific site, functional, and operational conditions. Upon consideration of variance CFM shall be consulted, and each Administration will function as Authority Having Jurisdiction for decision. Each substantial variance shall have a basis rationale and be documented in the project record;

2) Clinicians, providers, primary users, and other stakeholders shall be involved in all phases of project development to best adapt Standards for specific functional, operational, and site conditions, and to provide optimum service environments for Veterans. This also includes installations and modifications of systems or technology involving safety, security, functionality, or environmental quality. Stakeholder involvement shall be documented in the project record.

VA TIL Standards are not project-specific. It is impossible to foresee all rapidly evolving requirements of VA facilities and each site or project will have unique requirements or conditions. Site-specific issues must be addressed within the context of these standards and applied to each individual project. Use these Standards does not preclude the need for, nor absolve planners, designers, and constructors of their responsibility to provide complete, http://www.cfm.va.gov/TIL

GENERAL v functional, safe, and secure designs suited to the unique requirements of each project, within budget, and on schedule.

Materials, equipment and systems are shown in an illustrative, performance-based format and are not intended to depict, suggest, or otherwise constitute endorsement of any specific product or manufacturer. Manufacturers should be consulted for actual dimensions, configurations, and utility requirements.

For additional information regarding the VA Technical Information Library and development and application of VA planning, design, and construction standards, please contact Donald L.

INTRODUCTION

This VA HVAC Design Manual for the Department of Veterans Affairs (VA) Healthcare Facilities is the only detailed design requirements manual for VA. The original 2017 version has been edited several times since first publication to keep the information updated and synchronized with the latest industry trends. VA lessons learned, collected from VHA clinicians and operations personnel, have been incorporated as well. The November 1, 2021 revision of this manual includes high priority changes recommended by the VA CFM/VHA HVAC committee in response to the COVID-19 pandemic. Compliance to the Design Manual, which promulgates minimum performance design standards for VA owned and leased new buildings and renovated facilities, ensures that VA facilities will be of the highest quality to support Veterans Health Care.

The Office of Construction and Facilities Management (CFM) is responsible for developing and maintaining this Design Manual. Revisions are made as necessary. The Architect/Engineers (A/E), Project Managers (PM), Resident Engineers (RE), Contractors, and Consultants should refer to the VA Directives, VA Policies, VA Design Alerts and Memorandums before each use of this design manual to note any updates that have been made since the last use. The VA Design Manuals 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 projects performed in the modernization, alteration, addition, or improvement of its real property and the construction of new structures. VA design Manuals and Master Specifications specify additional codes and standards that VA follows on its projects.

Design, construction, renovation and installation of all VA Facilities must be in accordance with this Design Manual and with the latest editions and/or revisions of all applicable codes, policies and standards. Nothing in this Design Manual should be construed as authorization or permission to disregard or violate local and legal requirements.

Variance from this Design Manual may be proposed to promote new concepts and design enhancements. Variance shall not conflict with Federal Regulations, Public Laws, Executive Orders, or the needs of the end users. All variances shall be reviewed by the VHA Office of Healthcare Engineering (OHE) in consultation with CFM Consulting Support Service (CSS).

Any reviewed variances are subject to written approval by the VA Authority. The VA Authority for all VHA projects is the Director of the Office of Healthcare Engineering. The VA Authority for VBA and NCA projects is the Director of the Office of Construction and Facilities Management (CFM). Request for variance shall be submitted in writing by the A/E through the COR in sufficient detail to explain the issues.

The VA Authority for all VHA projects is the Director of the Office of Healthcare Engineering (OHE). The VA Authority for VACO, VBA and NCA projects is the Director of the Office of Construction and Facilities Management (CFM). Request for deviations shall be submitted in writing by the A/E through the COR in sufficient detail to explain the issues. The amount of documentation will vary on a case by case basis but in general may contain some or all of the following elements:

• Narrative explanation of the requested deviation (provided in all cases).

• Construction cost impact (provided in all cases).

• Construction schedule impact (provided in all cases).

• Equipment and material data sheets when applicable.

• Photographs of existing conditions when applicable.

BASIC REQUIREMENTS 1-3

• Calculations, including cost estimates.

• Drawings and sketches.

• Other background information such as codes, standards etc.

The complete request for deviation shall include all the required elements listed above in a concise narrative package with supporting data which clearly communicate what the deviation is, why the deviation is being requested, and the operational, maintenance, energy, cost, and schedule impacts of accepting the deviation and of rejecting the deviation.

1.2 ENERGY CONSERVATION

Refer to the VA Sustainable Design Manual, May 6, 2014 or approved latest edition available at the time design NTP is issued.

1.2.1 ENERGY REDUCTION REQUIREMENT - NEW CONSTRUCTION

All new buildings and/or additions to existing buildings entering design on or after April 7, 2023, must be designed to meet the minimum requirements of ASHRAE 90.1-2019. In addition, if lifecycle cost-effective, reduce site energy use by 30 percent compared to the baseline building performance rating per ASHRAE 90.1-2019, Appendix G. If a lifecycle cost effective design cannot be achieved that meets the 30 percent reduction requirements, select the most efficient design that meets or exceeds the minimum requirements and is lifecycle cost-effective.

1.2.2 ENERGY REDUCTION REQUIREMENT - MAJOR RENOVATIONS

Comply with requirement to achieve LEED Silver certification contained in CFM Policy Memo 003C-2021-21 (Green Building Certification Requirement) and Standards Alert 018 (Green Building Certification Standard Update).

Meet the minimum requirements of LEED v4.1 Energy and Atmosphere prerequisite “Minimum Energy Performance.” In addition, achieve a minimum of five points (20% better than ASHRAE 90.1-2016) under LEED v4.1 Energy and Atmosphere Credit “Optimize Energy Performance,” if lifecycle cost-effective. If five points cannot be achieved in a LCC-effective manner, design to achieve the highest number of points that are LCC-effective.

1.2.3 LIFE-CYCLE COST ANALYSIS – METHODOLOGY

An engineering and economic analysis shall be performed in accordance with the procedure outlined by the DOE in the National Institute of Standards and Technology (NIST) Handbook 135 dated February 1996 (or the approved latest edition) – Life-Cycle Costing Manual for the Federal Energy Management Program.
