NEW QUESTION # 87
A LEED Building Design and Construction project includes an outdoor stage for theatrical performances. In pursuit of Sustainable Sites Credit, Light Pollution Reduction the engineer has specified an LED fixture to illuminate actors on the stage while limiting light pollution. Which of the following suggestions should the LEED AP give to the project owner?
- A. Compare the energy consumption against an alternative
- B. Calculate the return on investment over the 20-year life of the project
- C. Modify the design to enclose the performance areas
- D. Inform the owner that the LED fixture is exempt from Sustainable Sites Credit, Light Pollution Reduction
Answer: D
Explanation:
The Sustainable Sites Credit, Light Pollution Reduction aims to minimize the adverse effects of artificial lighting on the night sky, human health, and wildlife1. However, the credit does not apply to lighting that is required for safety, security, or emergency purposes2. According to the LEED Reference Guide for Building Design and Construction, lighting for theatrical performances is considered an emergency purpose and is exempt from the credit requirements3. Therefore, the LEED AP should inform the owner that the LED fixture is exempt from Sustainable Sites Credit, Light Pollution Reduction and does not need to be modified or compared to an alternative. Enclosing the performance areas would not reduce light pollution, but rather increase energy consumption and affect the outdoor experience. Calculating the return on investment over the
20-year life of the project is irrelevant to the credit and would not help achieve it.
NEW QUESTION # 88
Innovation credits for exemplary performance can be awarded for
- A. achieving double the credit requirements
- B. achieving one pilot credit
- C. demonstrating a qualitative improvement in environmental performance
- D. demonstrating significant environmental benefits
Answer: A
Explanation:
Exemplary performance credits are one of the options to earn innovation points under the LEED v4.1 rating system. They are typically awarded for achieving double the credit requirements or the next incremental percentage threshold of an existing LEED v4.1 prerequisite or credit that allows exemplary performance. For example, to earn an exemplary performance point for the Energy and Atmosphere credit Optimize Energy Performance, the project must demonstrate a percentage improvement in the proposed building performance rating compared to the baseline building performance rating per ASHRAE 90.1-2010 by at least 12 percentage points for new construction, or by at least 16 percentage points for major renovations.

NEW QUESTION # 96
An HVAC system consists of an air handler supplying conditioned air (mixture of return air andoutdoor air) to anoffice, corridor, conference room and lobby. For Indoor Environmental Quality Prerequisite, Minimum Indoor AirQuality Performance, the ventilation rate procedure calculations must be based upon what HVAC systemconfiguration?
- A. Multiple-zone system
- B. 100% outdoor air system
- C. Single-zone system
- D. Mixed-mode system
Answer: A
Explanation:
Explanation
A multiple-zone system is a system that has one or more air handlers supplying conditioned air to more than one zone. A zone is a space or group of spaces within a building with heating and cooling requirements that are sufficiently similar so that desired conditions (e.g., temperature) can be maintained throughout using a single controlling device. The ventilation rate procedure calculations must be based on the multiple-zone system configuration because the HVAC system in the question serves different zones with different ventilation requirements.References: LEED v4 Reference Guide for Building Design and Construction, p.6881; ASHRAE Standard 62.1-2010, Section 6.2.52
NEW QUESTION # 97
Increasing which of the following variables will require an increase in the outdoor airflow rate under Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance?
- A. Number of occupants
- B. System ventilation efficiency
- C. Supply air temperature set point
- D. Supply air velocity
Answer: A
Explanation:
The outdoor airflow rate is the amount of outdoor air that is supplied to the building by the ventilation system to dilute indoor air pollutants and provide fresh air for the occupants. The outdoor airflow rate depends on the ventilation standard that the project follows, which can be either ASHRAE 62.1-2010 or CEN Standard EN 15251-20071. Both standards specify the minimum outdoor airflow rate per person and per unit area for different occupancy types and zones. Therefore, increasing the number of occupants will require an increase in the outdoor airflow rate to maintain the minimum ventilation level. The other variables, such as supply air velocity, system ventilation efficiency, and supply air temperature set point, do not directly affect the outdoor airflow rate, although they may influence the energy consumption and thermal comfort of the ventilation system.

NEW QUESTION # 104
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. 12,500 ft2 (1 160 m2)
- C. 35,000 ft2 (3 250 m2)
- D. 15,000 ft2 (1 400 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). References: SS Credit Site Development - Protect or Restore Habitat, LEED v4 Reference Guide for Building Design and Construction13
