83 Arrowstreet Contracts and LEED 83 Section 6

84 Arrowstreet Contracting for LEED Design Services Example Green contract clauses: The LEED Rating System utilizes certain design and usability recommendations on a project in order to promote an environmentally friendly and energy efficient facility. In addressing these guidelines, the Design Professional shall perform its services consistent with the professional skill and care ordinarily provided by design professionals practicing in the same or similar locality under the same or similar circumstances. The Owner acknowledges and understands, however, that LEED is subject to various and possibly contradictory interpretations. Furthermore, compliance may involve factors beyond the control of the Design Professional including, but not limited to, the Owners use and operation of the completed project. It is recognized that neither the Architect nor the Owner has control over the USGBC and GBCI review and evaluation of the Projects LEED Certification Application. Accordingly, the Architect cannot and does not warrant or represent that the LEED Certification Application will be approved by the USGBC and shall not be liable for consequential damages from the USGBCs decision not to award Certification.

85 Arrowstreet Energy Design Goals vs. Actual Energy Usage If the Owners program (Basis of Design) includes requirements for Project energy usage, the Owner MUST confirm the energy goals and usage in writing to the Design Professional. The Owner must recognize that the achievement of such goals or requirements is subject to operational, maintenance activities and other factors and decisions over which the Design Professional has no control. Therefore, the Design Professional shall use reasonable care in its design to achieve the energy usage goals or requirements but can make no warranty or guarantee regarding actual energy usage.

86 Arrowstreet Agreements Required for LEED Registration and Certification

87 Arrowstreet LEED 2009 Minimum Program Requirements 6. MUST COMMIT TO SHARING WHOLE-BUILDING ENERGY AND WATER USEAGE DATA All Rating Systems All Certified projects must commit to sharing with USGBC and/or GBCI all available actual whole-project energy and water usage data for a period of at least 5 years. This period starts on the date that the LEED project begins typical physical occupancy….or the date that the building is awarded certification. Sharing this data includes supplying information on a regular basis in a free, accessible, and secure online tool * or, if necessary, taking any action to authorize the collection of information directly from service or utility providers. This commitment must carry forward if the building or space changes ownership or lessee. * EPA Energy Star Building Portfolio Manager
