Which of the following Building Product Disclosure and Optimization credits under the Materials and Resources category would a project team achieve by using insulation material that is cradle-to-cradle V3 Gold certified?
Detailed
Cradle-to-cradle certification (Gold level) meets the requirements for Material Ingredient Optimization under Option 2. It demonstrates the product's compliance with advanced environmental standards, supporting the LEED focus on transparency and optimization of building materials to minimize their environmental and human health impacts.
A project team is considering implementing a strategy that has previously been awarded as an Innovation credit on another project. Which actions should be followed if the project team wishes to gain formal pre-approval of the same strategy on the new project?
Detailed
To gain formal pre-approval for a strategy previously awarded as an Innovation credit, the project team must submit a Credit Interpretation Request (CIR) to the Green Business Certification Inc. (GBCI). This allows GBCI to evaluate whether the strategy meets the intent of LEED Innovation credits for the specific project context.
What is the reference standard that defines the requirements for LEED energy modeling?
Detailed
ASHRAE 90.1-2010 Appendix G is the reference standard used for energy modeling in LEED projects. It establishes guidelines for baseline building performance and energy simulation comparisons, allowing project teams to demonstrate energy performance improvements relative to code-minimum buildings.
Where must a building's no-smoking signage be posted?
This is the requirement for the Indoor Environmental Quality prerequisite Environmental Tobacco Smoke Control, which applies to all LEED BD+C rating systems. The intent is to prevent or minimize exposure of building occupants, indoor surfaces, and ventilation air distribution systems to environmental tobacco smoke. The no-smoking signage must explicitly state the 25 ft. (8 m) limit and communicate the no-smoking policy to occupants.
When measuring sound pressure levels in a classroom to determine compliance with the HVAC background noise requirements of LEED Building Design and Construction: Schools, Indoor Environmental Quality Prerequisite, Minimum Acoustic Performance, what testing conditions are appropriate for the classroom?
To meet the Indoor Environmental Quality (IEQ) Prerequisite: Minimum Acoustic Performance for classrooms, sound pressure level measurements should be taken under conditions that reflect typical classroom use without occupants, ensuring accuracy in assessing HVAC background noise levels. Furnished, no occupants, HVAC operating at typical level (C) is the correct testing setup, as it accounts for sound absorption by furniture but excludes ambient noise from people. This setup provides a more accurate measure of the background noise levels produced by HVAC systems, ensuring compliance with acoustic performance requirements for optimal learning environments.
