LEED AP ID+C study guide
LEED AP ID+C · Work through your exam, one topic at a time.
LEED AP Interior Design + Construction (LEED AP ID+C) is a professional credential for people who design, build and deliver commercial interiors. GBCI, which administers LEED credentials, describes a LEED professional credential as a way to demonstrate proficiency in today's sustainable design, construction and operations standards and to show knowledge and credibility to employers and clients. The LEED AP ID+C study guide has 10 sections and about 2,899 words.
01LEED Process
LEED ID+C (Commercial Interiors, Retail, Hospitality) is points-based. Prerequisites are mandatory and worth zero points; credits are optional and worth points; total available points scale to 110 including Innovation.
311 words, about 2 min02Integrative Strategies
The Integrative Process credit rewards early, cross-discipline analysis rather than late add-ons. The team holds a goal-setting workshop (charrette) before schematic design, records the Owner's Project Requirements (OPR), and the design team then translates those goals into the Basis of Design (BOD).
285 words, about 1 min03Location and Transportation
Location and Transportation credits are largely decided by where the tenant leases space. Core credits cover surrounding density and diverse uses, access to quality transit, bicycle facilities, reduced parking footprint, and green vehicles (preferred parking, fueling infrastructure).
275 words, about 1 min04Sustainable Sites
Sustainable Sites is narrow in ID+C because a tenant controls little or no land. Credits available to interiors projects center on light pollution reduction, rainwater management, heat island reduction (roof and nonroof, including parking), and, where site work occurs, erosion and sedimentation control.
302 words, about 2 min05Water Efficiency
Water Efficiency in ID+C is almost entirely indoor water use. The prerequisite requires a 20% reduction from a calculated baseline, and the credit rewards progressively deeper reductions in tiers.
292 words, about 1 min06Energy and Atmosphere
Energy and Atmosphere is the heaviest category. Prerequisites include fundamental commissioning and verification, minimum energy performance modeled against an ASHRAE 90.1-2010 baseline, fundamental refrigerant management (no CFC-based refrigerants, or a phase-out plan), and energy metering.
289 words, about 1 min07Materials and Resources
Materials and Resources prerequisites are storage and collection of recyclables and a construction and demolition waste management plan written before work begins. Credits cover building life-cycle impact reduction (reusing existing building stock, reusing interior nonstructural elements, or a life-cycle assessment), building product disclosure and optimization (environmental product declarations, raw material sourcing, material ingredient reporting), and construction and demolition waste management with diversion tiers typically at 50% and 75%.
280 words, about 1 min08Indoor Environmental Quality
IEQ prerequisites start with minimum indoor air quality performance (ventilation rates per ASHRAE 62.1-2010 or the equivalent), environmental tobacco smoke control (no smoking inside; designated smoking areas at least 25 feet from entries, operable windows, and air intakes), and a construction IAQ management plan following SMACNA guidance: protect absorptive materials, control pollutant sources, and use appropriate filtration media during construction. Credits cover enhanced IAQ strategies, low-emitting materials (paints and coatings, adhesives and sealants, flooring systems, composite wood, ceilings and walls, insulation, and furniture), construction IAQ management with flush-out or air testing, thermal comfort per ASHRAE 55, interior lighting with controls and daylight, acoustic performance, green cleaning, and an IAQ assessment.
282 words, about 1 min09Innovation
Innovation rewards significant, measurable environmental performance that the rating system does not otherwise address. Points come from four routes: a genuinely new strategy, exemplary performance that reaches a defined higher tier or doubles a credit threshold, a pilot credit, or a strategy addressed elsewhere in the rating system but applied in a way that merits recognition with documented justification.
291 words, about 1 min10Project Surroundings and Public Outreach
An ID+C project sits inside a larger building, block, and neighborhood. This domain tests whether the team considered context beyond the lease line and communicated its sustainability work to the people it affects.
