In case of conflicting requirements, the more stringent requirements shall govern.

A/E shall incorporate into the design premium efficiency solutions to all issues related to water and energy.

Lighting:

• Lighting fixtures shall use LED technology to the maximum extent feasible. Color temp and CRI shall be appropriate for the application. Preferred fixture for lay-in applications:

o Lithonia 2x2 LED Lay-in Fixture Cat# 2GTL2LP840 o Lithonia 2x4 LED Lay-in Fixture Cat# 2GTL4LP840

• LED Exit signs (Replace all non-LED in project area with LED)

• Outdoor lighting. Use LED or Induction lighting in all outdoor applications where technology is available as a solution.

• Use of day lighting

• Use of light sensors etc. to harvest natural day light

• Use dual technology occupancy sensors

• No incandescent lighting

• All pilot/indicator lights to be LED

• Use occupancy sensors in all appropriate locations

(equipment/storage rooms, mechanical/electrical rooms with keyed-switch override, restrooms and locker rooms, offices, conference rooms, lounges/staff areas, all hallways in non-patient areas)

Motors:

• Premium efficiency motors with VFD drives.

HVAC:

• Maximize recirculation air to the extent permissible per ASHRAE

Std 62.1 procedures subject to VA HVAC Design Manual minimum OA requirements

• Air handlers with full economy cycles (where applicable)

• Air Handlers with thermal recovery systems (where applicable)

• VFD drives on all fan motors larger than 1 horsepower.

• After hour and night set back reducing air flow and allowing temperatures to swing through a larger range

• Use of VAV system where possible https://www.cfm.va.gov/til/sustain/dmSustain.pdf

• Allow a maximum of thermostats for individual control of temps in rooms (limit allowable temp range through programming)

• Enthalpy controls (where applicable)

• Full DDC control

• No single pass cooling with domestic water. Single pass with chilled water acceptable if it is returned through the chilled water return system.

Controls:

• DDC controls with after hour and night set back.

• Full commissioning of controls for any new equipment put on the system

• Consider use of CO2 sensors for control of air flow in common rooms, waiting rooms, conference rooms etc. (VAV systems only)

• Allow a maximum of thermostats for individual control of temps in rooms (limit allowable temp range through programming)

• Put lighting on DDC controlled contactors to shut lights off during non-operational hours (where conditions allow) Chillers

• Use centrifugal chillers with VFD drives on all systems 500 ton and larger

• Use micro centrifugal chillers for all chillers 30 – 200 ton

• All new chillers to be tied directly into building management systems for monitoring and control.

Boiler Plants

• Boilers shall have stack economizers.

• Boilers shall have automatic blow down.

• New Boilers shall have combustion air fans on VFD drive.

• Only the highest efficiency boilers should be considered for new plants.

• Boilers shall have automated oxygen trim controls

Medical Equipment:

• Highest energy efficient equipment available (when a choice is available)

• Select non-conditioned space for location of condensers when separate system cooling is required. (Place condensers in interstitial space, roof space, outdoors etc.)

• Increase exhaust air for rooms with large pieces of medical equipment to exhaust excess heat. (minimize return air for these rooms)

• When using a line UPS/Line conditioner, make sure unit draws power from the line side of the rectifier. (non-energy issue, but a good practice)

Washrooms/Bathrooms

• Urinals shall be low flow and/or dual flush

• Toilets shall be low flow and/or dual flush

• Sinks shall be laminar flow

• Sinks shall use incorporate sensors for automatic tempered water flow for hand washing

• Use hot water recirculation where possible

Windows/Glass

• Use of insulated glass (where conditions allow)

• Use of Low-E glass

Irrigation

• Include Grey water systems for irrigation system. Minimize the use of potable water.

Compliance with the Guiding Principles for Federal Leadership in High Performance and Sustainable Buildings (Guiding Principles, VA DIRECTIVE 0056 https://www.cfm.va.gov/til/sustain/dmSustain.pdf )

Sustainable Design Manual – 2014, Rev 1 18 Aug 2017 – Requirements Clarification.

1. Reference paragraph 2.4. NRM projects also require Validating Compliance per paragraph 2.4.1 and Commissioning per paragraph 2.5.

Design documents shall include requirements for the following:

New Construction. All new construction (of any size) shall meet, and are encouraged to exceed, the following criteria:

(1) Renewable energy shall account for 20 percent or more of electricity used in accordance with the Presidential Memorandum of December 5, 2013, if life cycle cost effective. A/E shall provide a detailed cost analysis that discusses the renewable energy options considered and the data necessary to determine whether renewable energy will be cost effective. Life cycle cost analysis shall follow the requirements referenced in the VA’s Sustainable Design Manual.

Renewable energy requirements may not be met with the purchase of renewable energy certificates or renewable energy generated outside of VA property.

(2) New construction shall use 30 percent less energy compared to the baseline building performance rating per the American National Standards Institute (ANSI)/American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc., (ASHRAE)/Illuminating Engineering Society of North America Standard (IESNA) Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential, if life cycle cost effective. The most recent version of ASHRAE 90.1 mandated for Federal use by the Department of Energy shall be used to establish the baseline. Combined heat and power and renewable generation shall be included in all projects, if life cycle cost effective.

(3) New construction projects shall comply with the requirements established in VA Directive 0056, Sustainable Buildings Program and VA Handbook 0056, Sustainable Buildings Program.

In the event that guidance conflicts between this Directive, Directive 0056, and other VA standards, the most energy-conserving requirement shall apply.

(6) If any required design criteria is not met for any reason, approval of exemption by the VA SSO shall be required. Any proposed changes related to the above criteria after the Detailed Design II phase, including during construction, must be approved by the VA SSO. A request for exemption approval with full documentation shall be submitted to the VA SSO prior to entering the next project phase.

(7) The VA SSO will consider the following reasons for exemptions: cost effectiveness, technical feasibility, mission-related conflicts, and other considerations. Documentation shall include the following:

(a) A description of the proposed deviation from the requirements.

(b) Life cycle cost calculations performed in accordance with EO 13423, 10 Code of Federal Regulations 436A, and EISA 2007 Section 441 and related calculations.

(c) All assumptions and data used for energy analyses or simulations to support the design team’s recommendation.

(d) The maximum level of proposed compliance feasibly achievable for each requirement.

(e) The request for exemption shall be approved and signed by the Director of the VA program office responsible for the project.

Minor Construction and Renovation (less than $20 million):

• Project must be designed and constructed to meet the Guiding Principles as applicable.

• To demonstrate compliance with the Guiding Principles:

o After construction is complete, the construction contractor must complete the checklists for LEED/Guiding Principles and Green Globes/Guiding Principles as applicable. Checklists are appended to this supplement. Guiding Principle references are taken from VA HANDBOOK 0056, Appendix A.

(http://www.va.gov/vapubs/viewPublication.asp?Pub_ID=640&FType=2) o The checklist must be verified by a third-party assessor with professional sustainable building credentials (e.g. LEED-AP, Green Globes Professional, or equivalent). If the project does not use LEED or Green Globes assessors, the checklist must be verified and stamped by a Professional Engineer.

o The construction contractor shall submit qualifications for the third-party assessor to the VA for approval.

o Elements of the checklist that are not applicable shall be determined by the third-party assessor and verified by the VA project manager and shall be annotated on the checklist with supplementary explanation attached in an addendum regarding the reason the element was omitted.

o The VA Project Manager will sign the appropriate checklist to verify compliance with the Guiding Principles provide to Office of Asset Enterprise Management (OAEM) by December 1 of the calendar year in which VA received the third-party certification for annual reporting purposes.
