8 Regional Priority:
USGBC regional councils have identified distinct environmental zones within their areas and allocated 6 credits to encourage design teams to focus on regional priorities. Wherever your project is located, check the website and find out which Regional Priority Credits have been identified by the Regional Chapter as important credits. When a project is registered with LEED online the project’s location is used to automatically credit the project with any regional priority credits that are earned. Project that earns a Regional Priority credit automatically earns one point in addition to any points awarded for that credit. Regional priority credits and points are for normal LEED credits. They are not new credits written for each region. 6 credits have been identified as regional priorities, but only 4 of those points can be achieved. Regional priority credits are specific to LEED project type (Schools, Healthcare, data center, etc.). USGBC chapters and LEED international Roundtable responsible for identifying regional priorities. In the pre-design stage, identify what regional priority credits are available for the project.
9 General information’s
Integrative Design credit is optional for all rating system except LEED for healthcare. Discovery phase commonly refers to schematic design, pre-design, or analysis of rough for. Integrative process phases: (Discovery, Design and Construction, occupancy, operation and performance feedback). Integrative Process (IP) at least 1 non-potable water supply source must be used to offset 2 water demand components (Indoor, Outdoor, Process). IP energy and water must be calculated together. IP prerequisite integrative project planning and design Preliminary energy analysis model only options that have large consequences on energy use. 1. IP energy analysis consider 7 aspects and must assess 2 strategies for each aspect Thermal comfort range Building envelop attributes
Lighting levels Plug and process load needs
Site conditions Massing and orientation Programmatic and operation parameters
2. Convene a goal setting workshop after preliminary energy and water research and analysis. 3. Water budget analysis occurs after the goal setting workshop. The concept model simple box energy analysis part of the IP can be used as the basis of the preliminary energy model for a whole-building energy simulation. IP prerequisite integrative project planning and design requires 4 hours integrated design charrette to optimize the integration of green strategies f or LEED BD+C: Healthcare o Charrette is used to accomplish several tasks which must be documentation a project narrative and an action plan for credit submittal. o Develop a health mission statement and incorporate it in the OPR, health mission statement must address the triple bottom line. Project team can avoid errors and expenses in LEED documentation prior to submitting the project for review by: (Check for completeness, Proofread the submission, verify the numeric value). Submit CIR if project team needs guidance on an issue before submitting for certification review, the CIR will be reviewed by a GBCI certification reviewer. USGBC steering committee would be used for LEED interpretations.
EPA target finder can be used to benchmark energy performance for the project’s type, occupancy
and location. Preliminary Rating goals: as early as practical and preferably before schematic design, conduct a preliminary LEED meeting with minimu m of 4 key project team members and the owner or owner’s representative as part of the meeting created a LEED action plan that at minimum: o Determine the LEED certification level to pursue. o Selects the LEED credits to meet the targeted certification level. Identifies the responsible parties to ensure the LEED requirements for each perquisite & credit. Contact LEED technical customer service to provide assistant with existing LEED guidance or process. When dealing with and issue not addressed in available LEED guidance materials, project teams can submit a suggested approach during the standard LEED certification process, they will receive a determination in the review comments at the discretion of the reviewer assigned to the project. Credits in LEED rating system has direct impact on human health, development firms convey this information to clients, to communicate green building is healthier and more enjoyable for individual inside the building leading to increased productivity. LEED BD+C and LEED ID+C, submit for construction phase review no later than 2 years after the project substantially completed. o
Documents for low-emitting products: (3rd party certification, Testing reports, MSDS).
Regional Alternative Compliance: paths for LEED credits address different geographical and climatic regions while providing solutions to challenges found by projects at a regional level. When determining the total vehicle parking capacity, include off-street parking available to the project building’s users outside of the pr oject boundary. Project must follow addenda prior to the project registration and can choose to follow any addenda released after the project is registered. Building envelope performance is going to look at the following: Thermal mass Window performance Window size and orientation
Exterior shading devices
Wall and roof insulation
For option 1 Whole-Building Energy Simulation, if projects are also pursuing the Integrative Process credit, then the project team must identify the requirements for concept-level energy modeling to determine how to coordinate the overall model of development. The basic energy analysis for the Integrative Process credit must be done before conducting the energy simulation. Review the ANSI Consensus National Standard Guide 2.0 for Design and Construction of Sustainable Buildings and Communities to become familiarized with the Integrative Process. Design strategies used to reduce site disturbance and minimize the disruption to existing ecosystems and help earn SS Credit Site Development, Protect or Restore Habitat are: Staking the building program Tuck-under parking Sharing facilities with neighbors Calculating daily baseline for indoor water use: o Women: water closet 3 uses per day. o Men: water closet 1 use per day, urinals 2 uses per day. o Faucet: 3 uses per day per FTE, 30 seconds per use. Actions that should be taken to ensure the products meet the requirements of the building product disclosure and optimization: o Collect documentation of environmental claims for each product expected to contribute toward credit achievement and track each item purchased in the LEED ME offline calculator. o Conduct LEED-specific pre-construction meeting to review the credit requirements in detail and stress their importance. Products / materials that have additional VOC content requirements for EQ Enhanced IAQ strategies: o Composite wood must meet CARB requirements. o Wet-applied products like (interior paint applied on site) must meet CARB requirements. o Furniture must meet BIFMA requirements. LEED boundary for multiple building developments, the LEED project boundary maybe portion of the development as determined by the project team, project team determine the LEED boundary for each LEED project. LEED project boundary may not include land that is owned by a party other than which owns the LEED project unless, the land is associated with and support normal building operations for the LEED project building. If a project boundary is not obvious because of ownership by multiple entities, review the minimum program requirements (MPRs), it’s the first place to look for suggestions.
LEED boundary defined for a single building development as: Portion of project site submitted for LEED, entire project scope generally limited to site boundary. Special considerations that would be part of the LEED project scope, off-site amenities or shared facilities off site, since they fall outside of the LEED project boundary. Some of the ways that site assessment could influence the design are: o Locating buildings based on view corridors, transportation infrastructure, and adjacent properties. o Incorporating natural ventilation by utilizing prevailing winds and seasonal wind patterns while also considering noise and air pollution sources. o Optimizing on-site rainwater management based on soil t ypes and existing vegetation.
