Offerors are encouraged to design a cost-competitive facility that reflects, to the maximum extent possible, the Environmental Protection Agency’s environmental protection mission and its positive commitment to the communities where its facilities are located.

Mission components include but are not limited to:

  1. Protection of the environment and specific components of the environment, such as the use of non-CFC refrigerants and non-ozone depleting blowing agents, to protect the ozone layer;
  2. Energy efficiency and reduction in energy use, reflected in the design of HVAC systems, lighting systems, the maximum use of natural daylighting, energy conserving building envelops, other resource-conserving building components and systems, and use of incentive schemes offered by local utilities, such as subsidized Green Lights programs, to maximize enery efficiency.
  3. Use of recycled materials, such as insulations made from recycled materials, use of materials that minimize energy input, and use of materials derived from sustainable sources and processes,
  4. Where possible, minimize the use of packaging for building materials and packaging waste, and seek packaging that is readily recyclable,
  5. Use of materials and construction processes that result in good indoor air quality, such as low VOC paints, sealants, adhesives, and finishes.
  6. Water conservation, through low flow shower heads, and toilet room fixtures, landscaping with native species and drip irrigation systems.
  7. Facility design that supports EPA’s active recycling program, including features that provide for the smooth functioning of paper recycling and other recycling programs. Components of this system include collection areas, freight elevators and freight elevator areas, storage areas, and loading facilities thoughtfully designed to handle recycled material flows.
  8. Thoughtful operation and maintenance of the facility after construction to insure good Indoor Air Quality, continuing energy efficiency, and ongoing conservation of natural resources, and
  9. Other energy, material, and pollution prevention initiatives.

There are inherent conflicts and compromises that must be resolved in attaining all these goals. The challenge is to minimize the conflicts and maximize the benefits in this project.

1.2.1 Finish Installation/Sequencing for Indoor Air Quality Considerations

Special construction scheduling involves defining and controlling sequencing of finishes applications to ensure dissipation of high emissions from the finishes that off-gas unacceptably high quantities of potentially harmful material during curing, and to separate and avoid the installation of adsorptive materials that would act as a "sink" for storage and subsequent release of these unwanted substances into building spaces and mechanical systems after project occupancy. Special procedures involve provision of temporary construction ventilation as well as restrictions and controls on the use of building mechanical systems to prevent contamination by construction wastes and other deleterious substances.

Type 1 Materials and Finishes: Materials and finishes which have a potential for short-term levels of off-gassing from chemicals inherent in their manufacturing process, or which are applied in a form requiring vehicles or carriers for spreading which release a high level of particulate matter in the process of installation and/or curing. Type 1 Finishes include, but are not limited to the following:

  1. Composite wood products, specifically including particle board and plywood from which millwork, wood paneling, doors, or furniture may be fabricated.
  2. Adhesives, sealants, and glazing compounds.
  3. Wood preservatives, wood finishes, primers and paints, and paint-like finishes.
  4. Control and/or expansion joint fillers, fire stopping materials, and caulking.
  5. Hard Finishes requirement adhesive installation including but not limited to plastic laminate, linoleum, and rubber tile.
  6. Gypsum board and associated finish processes and products.

Type 2 Finishes: Soft materials and finishes which are woven, fibrous, or porous in nature and may adsorb chemicals off-gassed by Type 1 Finishes, or may be adversely affected by airborne particulates. These materials have the potential to become sinks for deleterious substances which may be released much later, or act as collectors of contaminates that may promote subsequent bacterial growth. Type 2 Finishes include, but are not limited to the following:

  1. Carpet and padding, and other woven or fibrous floor finishes.
  2. Fabric wall covering
  3. Insulation materials exposed to the airstream.
  4. Acoustic ceiling materials
  5. Furnishings and fabric coverings

Note: Materials that can be categorized as both Type 1 and Type 2 materials shall be considered Type 1 Materials.

Offeror shall sequence construction to complete off-gassing of Type I materials prior to installation of Type 2 materials during the construction, build out, and finishing of the space and segregate the operation of the HVAC systems so that emissions in works zones do not contaminate areas where construction and installation of Type 2 materials and finishes has been completed.

At a minimum, following completion of installation of Type 1 materials in an area, the facility should be off-gassed for at least 48 hours, unless curing schedules provided by materials manufacturers call for a longer curing process, in which case, an appropriate and longer period for off-gassing should be used. Provide the maximum rate of fresh air to the HVAC system during the off-gassing period.

The HVAC system may be used to move both supply and return air except that permanent return air ductwork or finished plenum systems shall not be used in areas subject to any construction or finish installation work. No recirculating of inside air is permitted -- temporary exhaust systems must be used with exhaust air directly to the outside from the construction area.

Apply all Type 1 interior finishes throughout the entire controlled building segment and allow such finishes to completely cure according to intervals and times stated in respective finish manufacturer’s printed instructions before commencing installation of any Type 2 materials in the same area. Do not store any Type 2 materials in areas where installation or curing of Type 1 Materials is in progress.

1.2.2 Off-Gassing After Completion of Interior Fit Up/Furniture Installation

At a minimum, following completion of the interior build out and installation of tenant furniture, the facility should be off-gassed for at least 48 hours prior to occupancy. Provide the maximum rate of fresh air to the HVAC system while maintaining other normal operating parameters and conditions regarding humidity and temperature.

Where construction and finish work is being performed in portions of a building while other parts of the building are being occupied, each construction and finish work area shall be segregated from the HVAC system so that exhaust from the construction and finish work area does not enter into the HVAC system and contaminate parts of the building where construction and finish work and/or furniture installation is complete.

HVAC ductwork should be sealed and protected from dust and dirt infiltration during construction, especially for dust generating activities such as gypsum wall board finishing and sanding.
