Pilot-Credits PC48: Discovery—Analysis to Support Integrative Process

  • Achieving integrative results

    Note: This pilot credit was closed for new registrations as of March 1, 2012.

    The Integrative Process credits seek to answer the question, “How can we achieve an integrative result that augments performance, maintains cost, and in a simplified way that is replicable and measurable?”

    Throughout the process of answering these questions, the Integrative Process credits underwent significant improvements between the 1st and 2nd LEED 2012 Public Comment periods. Integrative thinking as it pertains to buildings is about completing the design process differently; however, to the extent possible, outcome has been made the primary goal of the credits.  The value in the credits requirements is in demonstrating an improved project than a team would have had without it, in terms of performance, satisfaction, and long-term cost.

    Pilot Credit 48, Discovery: Analysis to Support Integrative Process, is intended to reward project teams who gather data, conduct analyses, and develop an understanding of the issues critical to the design of a project seeking to achieve high performance, before design and building form, interior form, and program systems decisions are made. This process will determine a team’s opportunity for success in terms of operation and satisfaction.

    Credit Specific

    Building Design and Construction

    • Provide a narrative report explaining the relationships among the energy load reduction elements (Massing and orientation; Solar gain on facades, and roof; Insulation; Glazing characteristics; Window-to-wall ratio (aperture percentage); Lighting power density; Operational parameters; Thermal comfort ranges) on the project site and how these features influenced the project design.

    Pilot Credit 48: Discovery: Analysis to Support Integrative Process

    Intent

    Encourage project teams to gather data, conduct analyses, and develop an understanding of key issues to be considered before decisions are made on design and building form to support integrative approaches aimed at achieving a high level of performance.

    Requirements

    Building Design and Construction Requirements


    NC, CS, Schools, Retail NC, Healthcare

    Using an integrative process, complete the following analyses:

    Energy Load Reduction

    During pre-design, analyze the following parameters (variables) for the building:

    • Massing and orientation;
    • Solar gain on facades, and roof;
    • Insulation
    • Glazing characteristics
    • Window-to wall ratio (aperture percentage)
    • Lighting power density
    • Operational parameters
    • Thermal comfort ranges

    Include adjacent siteA site having at least 25% of its perimeter bordering sites that has been previously developed. Any fraction of the perimeter that borders waterfront will be excluded from the calculation. For the purposes of this definition, a street or roadway does not constitute previously developed land. conditions in the analysis; it is not necessary to include parameters or energy efficiency measures that are independent of the building form (this may mean HVAC system selection, renewable energy systems, and other mechanical and efficiency based parameters). Select at least five load reduction parameters and run at least two scenarios in addition to the baseline case used for EAp1 and EAc1. Provide a narrative report explaining the relationships among the above elements on the project site and how these features influenced the project design.

    Water Systems

    Perform a water balance analysis that quantifies all water input and output to and from the building and site.  Identify strategies for water use that reduce burden on municipal supply and wastewater treatment systems, increase local aquifer recharge, and address impacts and benefits of any water leaving the site.  Provide a narrative explaining the relationships among the above elements on the project site and how these features influenced the project design.

    Site Assessment

    Conduct a site analysis that considers the criteria outlined in SSc1 Site Assessment. Identify strategies that will improve the health of the living aspects of the site. These aspects may include soil health, plant and animal health, plant and animal interrelationships to increase diversity and resiliency, reduced water use, more effective ground water recharge, reduced erosion, improved microclimate as appropriate for the context ecosystem, improved human habitat, and so on. Provide a narrative report explaining the healthy relationships among the above aspects and how these features influenced the site and project design. 


    Interior Design and Construction Requirements


    CI, Retail

    Prior to site selection, create a document of project goals to aid in the selection of a building that will provide the most opportunities and fewest barriers for the Commercial Interiors project.  Goals must include the following considerations:

    • Building Site Features: Include location and site design characteristics;
    • Base Building Features: Include building envelope, building systems (such as controls, HVAC, and plumbing fixtures), adaptability to future needs, and resilience in the event of disaster or infrastructure failure;
    • Occupant Wellbeing Features: Include daylight and views, indoor air quality, and other items controlled by the base building. 

    AND

    Complete an assessment of the tenant occupants’ transportation needs for daily commuting to and from the site. Establish criteria for convenient access to alternative transportation most beneficial to the occupants’ destinations that can be used to determine preferred tenant location.

    Demonstrate that an integrative process with interiors expertise was used to evaluate the suitability of two of more potential tenant spaces relative to the building site features, base building features, occupant wellbeing features, and daily occupant commuting needs desired by the project team.  Provide a building qualification analysis of the potential sites based on all criteria and explain how the selected tenant space addresses the project goals and transportation needs of occupants. 


    Existing Buildings: Operations + Maintenance Requirements


    Case 1: Building Age is Less Than 15 Years – Ongoing Post-Occupancy Analysis and Evaluation

    Demonstrate use of an integrative process to perform a postoccupancy analysis and evaluation to understand the building’s performance relative to design intentA written document that details the ideas, concepts, and criteria that are determined by the owner to be important to the success of the project. and occupant satisfaction, and identify integrative strategies for improvement.  Establish and use ongoing feedback mechanisms among owner/management, operations staff, and tenants that provide information about building performance and systematically evaluate occupant satisfaction.  Include feedback from building and facility management, and where appropriate, all interested tenants.    Conduct building performance modeling calibrated against the utility data of the building. Reconcile design and performance differences where possible. 

    Create an ongoing team of relevant stakeholders to allow integration of various perspectives. The team should participate in gathering and reviewing feedback, identifying issues, and proposing and prioritizing solutions based on consideration of all relevant systems and synergies. All interested stakeholders should have the opportunity to participate. Provide documentation of methods used to gather feedback on at least energy and water performance, occupant satisfaction, and facility manager experience with the building and its systems. Provide report identifying issues and opportunities for improvement based on feedback and rationale.

    Case 2: Building Age is Equal to or Greater than 15 Years – Analysis for Deep Retrofit

    Demonstrate use of an integrative team process to identify and evaluate deep retrofit opportunities at the project building. Perform an investment grade audit evaluating the operating characteristics of all energy consuming systems and situations that cause load profile variations on both an annual and daily basis.  Conduct building performance modeling calibrated against the utility data of the building.

Geraldine, it was closed for registrations in March 2012, and I'm not aware of plans to reopen it.

Pilot Credit 48 is not listed on the feedback survey

When completing the feedback survey, the list only went through PC 42. Did I miss something, or is PC 48 and others not yet available within the survey?
