d. For classification as a Green building, facilities must satisfy all of the
prerequisites and a certain number of credits to attain different SPiRiT certification
levels. Having satisfied the basic prerequisites of the rating tool, facilities are then rated
according to its degree of compliance (on a percentage basis) with the credit system
e. SPiRiT is divided into eight categories: sustainable sites, water efficiency, energy
and atmosphere, materials and resources, indoor environmental quality facility delivery
process, current missions, and future missions. The following is a synopsis of SPiRiT.
Sustainable Sites (Score 20) SPiRiT minimizes the impact of placing a building on a
site, with an eye to land use compatibility and biodiversity. It channels development to
installation areas with existing infrastructure, rehabilitates damaged sites, and reduces
impacts from automobile use. SPRT optimizes microclimate and minimizes effects on
neighboring sites of noise, light, runoff, pollution, etc.
Water Efficiency (Score 5 ) SPiRiT minimizes the use of potable water for landscape
irrigation and within the building.
Energy and Atmosphere (Score 28) SPiRiT ensures that buildings work as intended.
It establishes energy efficiency and optimization for the base building and systems and
encourages use of renewable and distributed energy systems. It reduces ozone
depletion and supports early compliance with the Montreal Protocol.
Materials and Resources (Score 13) SPiRiT reduces waste from construction and
building occupants and redirects recyclable material back to the manufacturing process.
It extends the life cycle of existing building stock, in part by extending the life cycle of
targeted building materials. It increases use of building products with recycled content
material and of locally manufactured building products. It reduces depletion of finite raw
materials and encourages environmentally responsible forest management.
Indoor Environmental Quality (IEQ) (Score 17) SPiRiT promotes indoor air quality
(IAQ) and prevents exposure to Environmental Tobacco Smoke (ETS). It provides a
high level of individual occupant control of thermal, ventilation, and lighting systems.
SPiRiT provides a connection between indoor spaces and the outdoor environment
through the introduction of sunlight and views into the occupied areas of the building.
SPiRiT provides appropriate acoustic conditions for user privacy and comfort.
Facility Delivery Process (Score 7 ) SPiRiT delivers a facility that optimizes tradeoffs
among sustainability, first costs, life cycle costs and mission requirements. It assures
that the delivery process assures efficient operation and maintenance of the facility.
Current Mission (Score 6 ) SPiRiT assures that the delivery process establishes
efficient operation and maintenance of the facility. It provides a high-quality, functional,
