The make and model of fixtures is required in determining the baseline for the Water Efficiency Prerequisite, Indoor Water Use Reduction.This information is used to calculate the baseline water consumption of the building, which is then compared to the proposed water use to determine the percentage reduction.

QUSTION NO: 147

In order to comply with Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies, Option 2. Additional Enhanced IAQ Strategies

A. all entrances to the building must have entryway systems 10 ft. (3 m) long in the direction of travel

B. CO2 monitors must be fitted in all densely occupied spaces and configured to provide an alert

C. all outdoor air supply systems must have an airflow measurement device that measures at least 90% of the airflow

D. all particle filters in the ventilation system must meet Comité Européen de Normalisation (CEN) standard Class F7 or better

Answer: D

To comply with the Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies, Option 2, all particle filters in the ventilation system must meet the Comité Européen de Normalisation (CEN) standard Class F7 or better.This requirement ensures that the air quality inside the building is maintained at a high standard, contributing tothe health and well-being of the occupants.References: LEED AP Building Design + Construction (LEED AP BD+C) V4 resources1

According to theLEED V5: Building Design + Construction Guide, the Location and Transportation Credit, Bicycle Facilities has two options: Option 1. Bicycle Network and Storage and Option 2. Reduced Parking Footprint. Option 1 requires the project to provide short-term bicycle storage for at least 2.5% of all peak visitors, and long-term bicycle storage for at least 5% of all regular building occupants. Short-term bicycle storage must be within 100 ft (30 m) walking distance of any main entrance, and long-term bicycle storage must be within 300 ft (90 m) walking or bicycling distance of any functional entry. Option 2 requires the project to provide short-term bicycle storage for at least 2.5% of all peak visitors, and long-term bicycle storage for at least 5% of all regular building occupants, and also reduce the total parking capacity by at least 20% from the base ratios.Both options can earn one point under this credit1.

If a commercial building is considered to have 100 peak visitors in a day, the minimum number of short-term bicycle storage spaces that must be provided to earn one point under Option 1 or Option 2 is 2.5% of 100, which is 2.5, rounded up to 3. However, the project must also provide long-term bicycle storage for at least 5% of all regular building occupants, which is not given in the question.Therefore, the correct answer is C, five, which is the minimum number of short-term bicycle storage spaces that must be provided to earn one point under Option 1 or Option 2, regardless of the number of regular building occupants.References:LEED V5: Building Design + Construction Guide, Location and Transportation Credit, Bicycle Facilities, Requirements1

LEED BD+C Location and Transportation (LT) Credit: High Priority Siteencourages development in locations with existing infrastructure to promotesustainable land use.

Option 1: Historic Districtapplies to projects located indesignated historic districtswhere at least75% of land within ½ mile (0.80 km) is previously developed.

Brownfields (Option C) and Federal Renewal Communities (Option D)areseparate site categoriesthat fall under differentHigh Priority Siteoptions.

The ¾ mile (1.20 km) radius in Option A is incorrect, as LEED specifically sets the requirement at½ mile (0.80 km).

Toearn this credit under Option 1, a project in a historic districtmust demonstrate that the surrounding land is predominantly redeveloped.
