IDEASS WE MR EQ

Overview

Sustainable design strategies and measuresare constantly evolving and improving.New technologies are continually intro-duced to the marketplace and up-to-datescientific research influences building de-sign strategies. The purpose of thisLEEDTM category is to recognize projectsfor innovative building features and sus-tainable building knowledge.

Innovation & Design ProcessOccasionally, a strategy results in build-ing performance that greatly exceeds thoserequired in an existing LEED credit.Other strategies may not be addressed by any LEED prerequisite or credit but war-rant consideration for their sustainability benefits. Finally, expertise in sustainablebuilding is essential to the design andconstruction process. All of these issuesare rewarded in this category.

Innovation in Design

IntentTo provide design teams and projects the opportunity to be awarded points for excep-tional performance above the requirements set by the LEED Green Building Rating System and/or innovative performance in Green Building categories not specifically addressed by the LEED Green Building Rating System.

RequirementsCredit 1.1 (1 point) Identify the intent of the proposed innovation credit, the

proposed requirements for compliance, the proposedsub-mittals to demonstrate compliance, and thedesign approach(strategies) that might be used to meet the requirements.

Credit 1.2 (1 point) Same as Credit 1.1Credit 1.3 (1 point) Same as Credit 1.1Credit 1.4 (1 point) Same as Credit 1.1

Submittals Provide the proposal(s) within the LEED Letter Template (including intent, re-

quirements, submittals and possible strategies) and relevant evidence of perfor-mance achieved.

Summary of Referenced StandardThere is no standard referenced for this credit.

IDEASS WE MR EQ Green Building ConcernsThe LEED Green Building Rating System was devised to address current sustainableissues involved in commercial building de-sign. However, the building industry is con-

stantly evolving and introducing new sus-tainable strategies and measures. It is im-portant to stay abreast of current develop-ments in sustainable building and incorpo-rate those strategies and products that opti-mize built spaces. Innovation credits are thevehicle by which LEED recognizes andawards such accomplishments. Additionally, innovation in design may beawarded if a project achieves exemplary performance under an existing LEED

credit. Points for exemplary performanceare available only for those credits wherethe outcome provides substantial benefits.

Environmental Issues With all sustainable design strategies andproducts, it is important to consider the re-

Credit 1lated impacts to the environment and occu-pant well-being, and to assure that otherbuilding aspects are not adversely impacted.

Economic IssuesInnovative strategies and measures have vari-able first costs and operating costs, depend-ing on the degree of complexity, materialsincorporated, and the novelty of the tech-nology. Initial costs can range from free toprohibitively expensive. To understand theimplications of design features, a life cycleanalysis can be applied to determine if thestrategy or product is cost-effective over thelifetime of the building.

Community Issues

Community issues are those that affectothers in close proximity to the project,as well as members of regional and worldcommunities. Local actions can have dra-matic effects on the world when consid-ered in aggregate.

Case Study

Phillip Merrill Environmental Center HeadquartersAnnapolis, Maryland

The Phillip Merrill Environmental Center Headquarters is a LEED Version 1.0 Platinum project housing the Chesapeake Bay Foundation. The project is located on 31 acres of diverse habitaton the Chesapeake Bay and functions as an office building as well as an education and training facility. A rigorous water effi-ciency program was instituted to minimize potable water use inthe building. A water recovery system collects roof runoff andfilters these volumes before reuse in non-potable applications suchas hand washing, mop sinks, dessicant makeup, and laundry. Thestored water is also used as supply for the fire suppression system.Potable water volumes are only used for showers and kitchen sinks.Composting toilets are used to further reduce potable water useand greatly reduce sewage volume. In aggregate, these measuresresult in water savings that exceed the Energy Policy Act (EPACT)of 1992 by over 90%, greatly exceeding the requirements of Wa-ter Efficiency Credit 3: Water Use Reduction.

Case StudyOquirrh Park Speed Skating OvalSalt Lake City, Utah

The Utah Olympic Speed Skating Oval is a LEED Version 1.0Certified project that hosted skating events for the 2002 Olym-

pic Winter Games. Several roof systems were analyzed for theproject and a cable suspension roof was chosen over conventionaltruss and arch systems for two significant benefits. First, the cablesuspension system reduced the enclosed volume of the building by 20% when compared with a parallel chord truss system. Thisresulted in a smaller HVAC system and lower air conditioning costs. The second benefit of the cable suspension system wassubstantial material use reduction. The weight of the chosensystem is 18 lbs/sf, 25% less than the next lightest system (a tiedarch roof). This resulted in an estimated savings of 600 tons of steel, equivalent to $850,000. Overall, the choice of the cablesuspension roof for the project reduced the amount of raw mate-rials and processing for the roof, reduced construction cost, andreduced operating costs over the lifetime of the building.

Design ApproachStrategiesThere are two types of innovation strate-gies that qualify under this credit. The

first type includes those strategies thatgreatly exceed the requirements of exist-ing LEED credits. For instance, a projectthat incorporates energy or water effi-ciency measures that provide extraordi-nary savings and greatly exceed the re-quirements of their respective LEED cred-its would be appropriate for this credit.Points for exemplary performance areavailable only for those credits where theoutcome provides outstanding, measur-able benefits to the environment and/or

building occupants.

The second type of innovation strategiesare those that are not addressed by any existing LEED credits. Only those strat-egies that have significant environmentaland occupant benefits are applicable.

Simple signage in a building would notbe considered a significant educationaleffort by itself. Conversely, a visitors cen-ter and interactive display, coupled witha Web site and video would be an appro-priate level of effort for earning an inno-vation credit. In other words, substantialefforts must be applied to innovationcredits. A separate set of submittals is re-quired for each point awarded and nostrategy can achieve more than one point.Four independent sustainability measuresmay be applied to this credit.

Credit 2Green Building ConcernsLEED Accredited Professionals have theexpertise required to design a building toLEED standards and to coordinate thedocumentation process that is necessary

for LEED certification. The AccreditedProfessional understands the importanceof integrated design and the need to con-sider interactions between the prerequi-sites and credits and their respective cri-teria. Architects, engineers, consultants,owners, and others who have a strong in-terest in sustainable building design areall appropriate candidates for accredita-tion. The Accredited Professional shouldbe the champion for the projects LEEDapplication and this person should be anintegral member of the project designteam.

Design ApproachStrategiesTo become a LEED Accredited Profes-sional, the LEED Accreditation Exammust be successfully passed. To preparefor the exam, it is helpful to attend a LEED Workshop offered by, or autho-rized by, the USGBC. Workshops includedetails on prerequisites and credits, cal-culation and documentation examples,and case studies from projects that haveachieved certification.For more information on workshops andthe Accreditation Exam, visit the LEEDsection of the USGBC Web site: www.leedbuilding.org.
