DBIA Sustainability and Green Building in Design-Build

Question 1

Design-build is considered particularly well-suited for sustainable (green) building projects primarily because:

Accepted Answer

The integrated team structure allows sustainability strategies to be optimized across design and construction simultaneously

Answer

Design-build's integrated team—where designers and builders collaborate from project inception—enables early identification and optimization of sustainability strategies that would otherwise be difficult to coordinate across separate design and construction contracts. Systems can be designed holistically for energy performance, with construction methods aligned to sustainability goals from the start.

Question 2

When an owner sets a LEED Gold certification requirement in a design-build RFP, this is best classified as:

Accepted Answer

A performance-based requirement defining an outcome the design-builder must achieve through its own means

Answer

Specifying a LEED certification level is a performance-based requirement—it defines the outcome (certification level) without dictating exactly how the design-builder must achieve it. This is consistent with design-build's philosophy of giving the integrated team flexibility to determine the best means and methods for meeting defined performance goals.

Question 3

Building Information Modeling (BIM) enhances design-build project delivery primarily by:

Accepted Answer

Enabling earlier clash detection and integrated coordination among design, structural, and MEP systems

Answer

BIM creates a shared digital model of the project that allows design, structural, and MEP/FP disciplines to coordinate in three dimensions, identifying conflicts (clashes) before construction begins. In design-build, where the integrated team controls both design and construction, BIM amplifies the collaboration advantage by enabling more informed decisions earlier in the process.

Question 4

An owner seeking to minimize a building's operational energy costs over a 20-year period should prioritize which approach when selecting a project delivery method?

Accepted Answer

Design-build with a total cost of ownership requirement, because the integrated team can optimize life-cycle performance from design inception

Answer

Design-build with a total cost of ownership or life-cycle cost requirement allows the integrated team to make design decisions—envelope performance, system selection, controls—that optimize energy consumption over the building's life rather than minimizing first cost. Separating design from construction typically incentivizes first-cost minimization, not life-cycle performance.

Question 5

Which of the following sustainability strategies is most effectively deployed in a design-build project during the pre-design phase?

Accepted Answer

Integrated passive design strategies such as building orientation, massing, and daylighting

Answer

Passive design strategies—orientation to minimize solar heat gain, building massing for natural ventilation, and daylighting optimization—must be established during pre-design and schematic design. These decisions are difficult or impossible to change later. Design-build's early designer-builder collaboration makes pre-design the ideal phase to lock in high-impact passive strategies.
