SECTION: SUSTAINABLE DESIGN REQUIREMENTS

GENERAL PHILOSOPHY: The General Services Administration (GSA) is committed to the purchase and use of environmentally sustainable products and services. “Green purchasing” is the procurement of sustainable products and services that contain recycled/recovered material(s);

are bio-based and/or non-ozone-depleting; are energy-efficient or water-efficient (are certified

ENERGY STAR and/or Water Sense); contain chemicals that are less ozone-depleting or hazardous; or have other sustainable attributes.

REQUIREMENTS FOR VENDORS/CONTRACTORS: Vendors/Contractors are required to consider and use “green (sustainable) products” if at all possible when providing any goods and/or services to the GSA.

The only three (3) exceptions to the requirements for “green products” are:

1. Unavailability

2. Products meeting the requirements do not satisfy performance requirements

3. The green product is only available at an unreasonable price.

Any exception must be documented and discussed with your GSA Contracting Officer prior to submission of your offer/proposal. In the case of unreasonable pricing, the price of the green product must be furnished and compared to the price of the product proposed for use. If you have questions regarding this please contact your GSA Contracting Officer.

3. Head-capacity curves shall slope up to maximum head at shut-off.

Curves shall be relatively flat for closed systems. Select pumps near the midrange of the curve, so the design capacity falls to the left of the best efficiency point, to allow a cushion for the usual drift to the right in operation, without approaching the pump curve end point and possible cavitation and unstable operation. Select pumps for open systems so that required net positive suction head

(NPSHR) does not exceed the net positive head available (NPSHA).
