Recognized Green Building Programs
Benchmarking tools provide evidence that projects have implemented specific sustainable building strategies.  Commercial projects in Seattle can use a variety of tools to demonstrate performance accomplishments, including:

• Green Factor - Seattle's menu of landscaping strategies to help achieve 30% parcel vegetation coverage required for all new development in Neighborhod Commercial Zones.
• Eco-Charrettes
• LEED for Commercial Buildings - a voluntary, national green building standard and certification system. The City uses LEED as a benchmarking tool with broad industry support.  We apply our incentives to it and take advantage of third-party verification.
• Green Guide for Health Care (GGHC) - a new high-performance and healthy-building initiative developed specifically for health care institutions and facilities

Design Strategies
Successful green building design requires a different approach to the way decisions are made. 

Conventionally the design process begins with the architect and client agreeing on a design concept, consisting of general massing, orientation, fenestration and general exterior appearance as determined by these characteristics and selection of basic materials.  Mechanical, electrical and structural engineers are then asked to implement the design and suggest appropriate systems. Contractors provide estimates and bids for the completed design, often but not always requiring major design adjustments to fit the owner’s budget.  The traditional process is mainly linear due to the successive contributions of the members of the design team.  There is limited opportunity for optimization during the traditional process, while optimization in the later stages is often troublesome, expensive or even impossible.

Green building requires breaking down the barriers that often exist between disciplines in order to permit greater communication and collaboration between parties, by involving all the players responsible for design to work together as a team from the outset.  This enables a variety of strategies to be quickly developed for consideration and testing, problems and inconsistencies to be pinpointed, and incompatible decisions to be identified and resolved early in the process.
