Integrative process

Intent

Implement an integrative process that supports high performance, cost-effective project outcomes through analyses of key systems interrelationships before decisions are made on building form and throughout the design process.

Requirements

Starting in pre-design, and continuing throughout the design phases, identify and execute synergistic opportunities for high performance outcomes across different disciplines and building systems. Use the analyses described below to inform the project’s Owner’s Project Requirements (OPR), Basis of Design (BOD), Design Documents, and Construction Documents. Consider opportunities resulting from analyses, at a minimum, in the following three areas:

Energy-related systems
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 other related sustainability goals by questioning default assumptions and testing options for applicable parameters. Assess at least two potential parametric options associated with, at a minimum, each of the following:

• Programmatic and operational parameters: Assess how multi-functioning spaces, operating schedules, space allotment per person, teleworking, reducing building area, on-going operations and maintenance issues impact project and human performance.
• Site conditions: Assess how shading, exterior lighting, hardscape, landscaping, and adjacent site conditions impact project and human performance
• Massing and orientation: Assess how massing and orientation impact HVAC sizing, energy consumption, lighting, and renewable energy opportunities.
• Basic Envelope Attributes: Assess how insulation values, window-to-wall ratios, glazing characteristics, shading, and window operability impact HVAC sizing, project performance, and human performance
• Lighting levels: Assess how interior surface reflectance values and lighting levels in occupied spaces impact HVAC sizing, project performance, and human performance.
• Thermal comfort ranges: Assess how thermal comfort range options impact HVAC sizing, project performance, and human performance.
• Plug and process load needs: Assess how reducing plug and process loads through programmatic solutions such as equipment and purchasing policies, layout options, etc., impact HVAC sizing, project performance, and human performance.

AND

Water-related systems
Perform a preliminary water budget analysis before the completion of Schematic Design that explores how to reduce potable water loads in the building and accomplish other related sustainability goals by assessing and quantifying the project’s potential non-potable water supply sources and water demand volumes. Assess applicable estimates for, at a minimum, the following:

• Indoor Water Demand: Assess flow and flush fixture performance case demand volumes, calculated in accordance with WEp Indoor Water Use Reduction.
• Outdoor Water Demand: Assess landscape irrigation performance case demand volume calculated in accordance with WEc Outdoor Water Use Recusion.
• Process Water Demand: Assess kitchen, laundry, cooling tower, and other equipment demand volumes, as applicable.
• Supply Sources: Assess all potential non-potable water supply source volumes, such as on-site rainwater and grey water, municipally supplied nonpotable water, and HVAC equipment condensate.

AND

Cost analysis (related to all above systems)
Discovery: Perform integrative cost-bundling analysis¹ that estimates the cost of implementing integrative strategies. Compare bundled design case first costs (associated with primary integrative strategies) with the project’s baseline first cost and operating costs budgets for the same components. This cost-bundling analysis must include, at a minimum, the following:

• Establish the project’s baseline construction budget using line item first cost estimates
• Establish the project’s baseline operations budget using line item cost estimates
• Create a cost-bundling spreadsheet identifying primary bundles of interrelated systems
• Identify and quantify potential design case first cost impacts (both reductions and increases) associated with each affected component of each primary bundle
• Identify potential design case operational costs associated with each primary bundle
• Identify any potential design case cost savings/benefits related to productivity issues associated with each primary bundle, where possible
