IDFX Sustainable Design and Green Building

Question 1

Which LEED credit category most directly addresses the selection of interior finishes and materials for their environmental performance?

Accepted Answer

Materials and Resources (MR)

Answer

Sustainable Sites (SS)

Answer

Water Efficiency (WE)

Answer

Indoor Environmental Quality (EQ)

Question 2

What does 'cradle-to-cradle' (C2C) design mean as applied to interior materials specification?

Accepted Answer

Materials are designed so all components can be either safely returned to biological cycles or continuously recycled in technical cycles, eliminating waste

Answer

Materials are selected based on their durability from installation through end of project life

Answer

Materials are sourced from within a 500-mile radius to minimize transportation impacts

Answer

Materials are certified to contain no VOCs from manufacturing through installation

Question 3

The concept of 'daylighting' in sustainable interior design specifically aims to achieve which outcome?

Accepted Answer

Introducing natural sunlight into interior spaces to reduce electric lighting energy use and support occupant health

Answer

Using electrical lighting programmed to simulate natural daylight color temperatures

Answer

Painting window frames white to maximize light reflection in dark interiors

Answer

Installing skylights in all occupied spaces regardless of solar orientation

Question 4

Forest Stewardship Council (FSC) certification for wood products used in interior design verifies which claim?

Accepted Answer

The wood was harvested from forests managed according to environmental, social, and economic standards

Answer

The wood product contains no formaldehyde binders or chemical adhesives

Answer

The wood was grown within 500 miles of the project site

Answer

The wood product carries a Class A fire rating

Question 5

What is the primary environmental concern associated with polyvinyl chloride (PVC) as an interior material?

Accepted Answer

PVC production involves chlorine chemistry and plasticizers (phthalates) that are persistent environmental and health hazards, and PVC releases toxic dioxins when incinerated

Answer

PVC releases high concentrations of radon gas during normal use

Answer

PVC is made from rapidly depleting petroleum reserves and cannot be recycled

Answer

PVC degrades rapidly under UV exposure, making it unsuitable for interior applications

Question 6

The WELL Building Standard's 'Thermal Comfort' concept is primarily based on which comfort standard?

Accepted Answer

ASHRAE 55 (thermal environmental conditions for human occupancy)

Answer

ASHRAE 90.1 (energy efficiency)

Answer

ASHRAE 62.1 (ventilation for acceptable indoor air quality)

Answer

ASHRAE 189.1 (sustainable buildings)
