OBJECTIVES Objective 1 Identify intent & requirements Objective 2 Identify strategies for success Objective 3 Recognize unique nature of IP as woven throughout the LEED v4 Rating System Objective 4 Recognize benefits of integrative approach Objective 5 Recognize synergies between credit categories Integrative Process (IP) – Main Ideas IP prioritizes cost effectiveness over both the short and long terms and engages all project team members in discovering beneficial interrelationships and synergies between systems and components. By integrating technical and living systems, the team can achieve high levels of building performance, human performance, and environmental benefits. Team members’ expertise in building and site systems can inform the performance, efficiency, and effectiveness of every system.
Integrative Process Devising a LEED Work Plan It is recommended that LEED applicants follow a series of 11 steps to certification: Step 1. Initiate discovery phase Step 2. Select LEED rating system Step 3. Check minimum program requirements Step 4. Establish project goals Step 5. Define LEED project scope Step 6. Develop LEED scorecard Step 7. Continue discovery phase Step 8. Continue iterative process Step 9. Assign roles and responsibilities Step 10. Develop consistent documentation Step 11. Perform quality assurance review and submit for certification

Integrative Process (IP) REQUIREMENTS Beginning in pre-design and continuing throughout the design phases, identify and use opportunities to achieve synergies across disciplines and building systems. Use the energy and water related analyses to inform the owner’s project requirements (OPR), basis of design (BOD), design documents, and construction documents.

Energy-related systems analysis: Discovery : Perform a preliminary “ simple box ” energy modeling analysis before the completion of schematic design that explores how to reduce energy loads in the building and accomplish related sustainability goals by questioning default assumptions. Assess at least two potential strategies associated with each of the following: Site conditions. Assess shading, exterior lighting, hardscape, landscaping, and adjacent site conditions. Massing and orientation. Assess massing and orientation affect HVAC sizing, energy consumption, lighting, and renewable energy opportunities. Basic envelope attributes. Assess insulation values, window- to-wall ratios, glazing characteristics, shading, and window operability.
Energy-related systems analysis: (Contd.) Lighting levels. Assess interior surface reflectance values and lighting levels in occupied spaces. Thermal comfort ranges. Assess thermal comfort range options. Plug and process load needs. Assess reducing plug and process loads through programmatic solutions. Programmatic and operational parameters. Assess multifunctioning spaces, operating schedules, space allotment per person, teleworking, reduction of building area, and anticipated operations and maintenance. Water-related systems analysis: Discovery : Perform a preliminary water budget analysis before completion of SD that explores how to reduce potable water loads in the building and accomplish related sustainability goals. Assess and estimate the project ’ s potential nonpotable water supply sources and water demand volume. Assess following: Indoor water demand. Flow and flush fixture design case demand volumes, calculated per WE Prerequisite Indoor Water- Use Reduction. Outdoor water demand . Landscape irrigation design case demand volume calculated per WE Credit Outdoor Water-Use Reduction. Process water demand . Kitchen, laundry, cooling tower, and other equipment demand volumes, as applicable. Supply sources . Assess all potential nonpotable water supply source volumes, such as on-site rainwater and graywater, municipally supplied nonpotable water, and HVAC condensate.
Energy-related systems analysis: Implementation : Document how the above analysis informed design and building form decisions in the project ’ s OPR and BOD and the eventual design of the project, including the following, as applicable: Building and site program Building form and geometry Building envelope and façade treatments on different orientations Elimination and/or significant downsizing of building systems (e.g., HVAC, lighting, controls, Exterior materials, interior finishes, and functional program elements) Water-related systems analysis: Implementation : Document how the analysis informed building and site design decisions in the project ’ s OPR and BOD. Demonstrate how at least one on-site nonpotable water supply source was used to reduce the burden on municipal supply or wastewater treatment systems by contributing to at least two of the water demand components. Demonstrate how the analysis informed the design of the project, including the following, as applicable: Plumbing systems Sewage conveyance and/or on-site treatment systems Rainwater quantity and quality management systems Landscaping, irrigation, and site elements Roofing systems and/or building form and geometry
Integrated Project Planning and Design Prerequisite in Healthcare Intent: Maximize opportunities for integrated, cost- effective adoption of green design and construction strategies, emphasizing human health as a fundamental evaluative criterion for building design, construction and operational strategies. Utilize innovative approaches and techniques for green design and construction.
