What can the team do to achieve Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies?
- A. Provide a large opening to dilute air contaminates
- B. Provide a hard-lid ceiling
- C. Create positive pressure in the room
- D. Use MERV 8 (F5), or higher, filters
Answer: B
Explanation:
The Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies aims to establish better quality indoor air for the building occupants that promotes their comfort and well-being1. This credit requires the project team to implement several strategies to reduce the exposure of occupants and HVAC systems to environmental tobacco smoke, airborne contaminants, and chemicals1. One of the strategies is to design and construct all interior partitions to full height (deck-to-deck) or provide a hard-lid ceiling for spaces where hazardous gases or chemicals may be present or used2. This strategy helps prevent the migration of contaminants from one space to another through the plenum3. A copy room is an example of such a space, as it may contain printers, copiers, toners, and solvents that can emit volatile organic compounds (VOCs) and particulate matter (PM) into the air4. Therefore, the project team can achieve Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies by providing a hard-lid ceiling for the copy room.

NEW QUESTION # 200
A project has total waste of 20 tons (18.1 tonnes) that includes the following:
* 8 tons (7.3 tonnes) of recycled demolition steel and concrete
* 2 tons (1.8 tonnes) of trees cleared from the site
. 3 tons (2.7 tonnes) of commingled scrap with 40% diverted
. 6 tons (5.4 tonnes) of used furniture donated to a non-profit organization
* 1 ton (0.9 tonnes) of removed carpet and ceiling tiles sent back to the manufacturer What is the percentage of diverted waste for Materials and Resources Credit, Construction and Demolition Waste Management?
- A. 90%
- B. 75%
- C. 100%
- D. 60%
Answer: B
Explanation:
The percentage of diverted waste for Materials and Resources Credit, Construction and Demolition Waste Management is calculated by dividing the total weight of diverted materials by the total weight of waste generated1. Diverted materials are those that are reused, recycled, salvaged, or donated2. In this case, the total weight of diverted materials is:
8 tons (7.3 tonnes) of recycled demolition steel and concrete
6 tons (5.4 tonnes) of used furniture donated to a non-profit organization
1 ton (0.9 tonnes) of removed carpet and ceiling tiles sent back to the manufacturer
40% of 3 tons (2.7 tonnes) of commingled scrap, which is 1.2 tons (1.1 tonnes) The sum of these weights is 16.2 tons (14.7 tonnes). The total weight of waste generated is 20 tons (18.1 tonnes). Therefore, the percentage of diverted waste is:
(16.2 / 20) x 100 = 81%
However, the credit allows for a 10% adjustment for vegetative waste, which is not considered a building material3. Therefore, the percentage of diverted waste after adjustment is:
(81 - 10) = 71%
The closest answer option to this value is B. 75%.

NEW QUESTION # 213
A new five-story building with a 30,000 ft2 (2 800 m2) footprint is being designed on a previously disturbed100,000 ft2 (9 290 m2) site. The remaining on-grade surface will be 35,000 ft2 (3 250 m2) of asphalt parking, and 35,000 ft2 (3 250 m2) of native vegetated open space. To achieve a point for exemplary performance under Option 1 of Sustainable Sites Credit, Site Development - Protect or Restore Habitat, the design team will have to incorporate a native and/or adapted vegetated roof with a minimum area of
- A. 25,000 ft2 (2 300 m2)
- B. 35,000 ft2 (3 250 m2)
- C. 15,000 ft2 (1 400 m2)
- D. 12,500 ft2 (1 160 m2)
Answer: A
Explanation:
According to the LEED v4 Reference Guide for Building Design and Construction, Option 1 of the Site Development - Protect or Restore Habitat credit requires restoring 25% of the site area (including the building footprint) with native or adapted vegetation1. To achieve exemplary performance, the project must double the credit requirements and restore 50% of the site area2. In this case, the site area is 100,000 ft2 (9 290 m2), so the project must restore 50,000 ft2 (4 645 m2) with vegetation. The project already has 35,000 ft2 (3 250 m2) of native vegetated open space, so it needs to add another 15,000 ft2 (1 395 m2) of vegetation. Since the on-grade surface is fully occupied by the building footprint and the asphalt parking, the only option is to incorporate a vegetated roof. Therefore, the design team will have to incorporate a native and/or adapted vegetated roof with a minimum area of 15,000 ft2 (1 395 m2).
