SECURE HVAC Sample Clauses
SECURE HVAC. OUTDOOR AIR INTAKES (NOV 2005)
A. Outdoor air intakes shall be relocated. The lowest edge of the outdoor air intakes shall be placed 40 feet, 0 inches above grade and not less than 30 feet, 0 inches from the loading dock. Access shall be locked and secured, if feasible. For increased visibility of suspicious items, moat areas and other ground level areas surrounding outside air intakes shall be completely free of trash, debris or any other matter.
B. Outdoor air intakes shall be extended. If relocation is not feasible, as approved by the Government, intake extensions shall be constructed without creating adverse effects on HVAC performance. The higher the extensions, the better, as long as other design constraints (excessive pressure loss, dynamic and static loads on structure) are considered. An extension height of 40 feet, 0 inches is required unless adverse effects on HVAC performance can be demonstrated. The entrance to the intake shall be covered with a sloped metal mesh to reduce the threat of objects being tossed in the intake. A minimum slope of 45 degrees may be required. Extension height shall be increased where existing platforms or building features (e.g., loading docks, retaining walls) might provide access to the outdoor air intakes.
C. A security zone around outdoor air intakes shall be established. When outdoor air intakes are publicly accessible and relocation or physical extensions are not viable options or are cost prohibitive, perimeter barriers that prevent public access to outdoor air intake areas shall be required based on the Government’s building security assessment. Iron fencing or similar see-through barriers may be required. The restricted area shall also include an open buffer zone between the public areas and the intake louvers. The Government will have the right to monitor the buffer zone by physical security and/or closed circuit television (CCTV). Security lighting or intrusion detection sensors are required and shall be provided and installed by the Lessor.
SECURE HVAC. DEDICATED HVAC FOR LOBBIES, MAILROOMS, AND LOADING DOCKS (NOV 2005) SECTION 4 DESIGN, CONSTRUCTION, AND POST AWARD ACTIVITIES
4.01 SCHEDULE FOR COMPLETION OF SPACE (AUG 2011)
▇. ▇▇▇▇▇▇-provided design intent drawings (DIDs): The Lessor must submit to DOE, as part of the shell cost, complete DIDs conforming to the requirements of this Lease and other Government-supplied information related to the tenant agency's interior build-out requirements not later than 30 working days following the lease award date, provided that the Government supplies such information and direction as reasonably required for Lessor to timely complete DIDs. The Government (DOE and the tenant agency) shall attend two meetings at the Lessor's request for the purpose of providing information and direction in the development of DIDs. The Lessor should anticipate at least two submissions of DIDs before receiving approval.
SECURE HVAC. DEDICATED HVAC FOR LOBBIES, MAILROOMS, AND LOADING DOCKS (BUILDING SHELL) (NOV 2005) To prevent widespread dispersion of a contaminant released within lobbies, mailrooms, and loading docks, the associated HVAC systems shall be isolated and the areas maintained by a dedicated exhaust system at a negative pressure relative to the rest of the building, but at a positive pressure relative to the outdoors. Physical isolation of these areas (well-sealed floor to roof-deck walls, sealed wall penetrations) is critical to maintaining the pressure differential and requires special attention to ensure airtight boundaries between these areas and adjacent spaces. A qualified HVAC professional can assist in determining if the recommended isolation is feasible for a given building. A modification to an existing system will likely require a re-evaluation of the existing HVAC system as well as potentially involving architectural and/or structural changes to the building. Any re-engineering of HVAC systems shall be estimated and costs identified to the Contracting Officer before beginning any proposed alterations. In addition, lobbies, mailrooms, and loading docks shall not share a return-air system. The Lessor shall provide lobby, mailroom, and loading dock ventilation systems' outside air intakes and exhausts with low leakage, fast acting, isolation dampers that can be closed to isolate their systems. Dedicated HVAC will be required for mailrooms only when the Government specifically requires a centrallyoperated mailroom. Non-Government building tenants may share the mailroom. Where possible, the mailroom shall be adjacent to the loading dock to prevent the possible contamination of additional areas within the building. Any mailroom or area where mail is received and sorted, shall have posted the telephone numbers of the Lessor/Owner’s building manager/engineer and local emergency personnel for emergency notification. Mailrooms shall also have posted a copy of the general precautions for mail handling.
