LEED v4 IPc1-Integrative Process

LEED v4 IPc1-Integrative Process

Any project can earn this credit, and it is readily achievable for teams that take an integrated approach from the project onset. The credit requires early analysis of energy and water systems in order to identify synergies within the project design that can optimize energy and water performance.

To earn this credit, teams must create a “simple box” energy model and perform a preliminary water budget analysis. Teams must then demonstrate how the preliminary analyses were used to optimize the design of the building’s energy- and water-related systems.

Following is the LEED language for this IP credit from the LEEDuser:

Intent

To support high-performance, cost-effective project outcomes through an early analysis of the interrelationships among systems.

Requirements

Beginning in pre-design and continuing throughout the design phases, identify and use opportunities to achieve synergies across disciplines and building systems described below. Use the analyses to inform the owner’s project requirements, basis of design, design documents, and construction documents.

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.
  • 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 (e.g., equipment and purchasing policies, layout options).
  • Programmatic and operational parameters. Assess multifunctioning spaces, operating schedules, space allotment per person, teleworking, reduction of building area, and anticipated operations and maintenance.
