QUESTION: 89

Which of the following projects is eligible to pursue the Energy and Atmosphere Prerequisite, Minimum Energy Performance, Option 2. Prescriptive Compliance: ASHRAE 50% Advanced Energy Design Guide?

50,000 ft2 (4 645 m2) office project
80,000 ft2 (7 432 m2) hospital project
110,000 ft2 (10 219 m2) school project
140,000 ft2 (13 006 m2) retail project

Answer(s): C

Explanation:

The Energy and Atmosphere Prerequisite, Minimum Energy Performance, Option 2. Prescriptive Compliance: ASHRAE 50% Advanced Energy Design Guide allows projects to follow the recommendations of the ASHRAE 50% Advanced Energy Design Guides (AEDGs) for different building types and climate zones. The AEDGs provide design guidance for buildings that use 50% less energy than those built to the requirements of the ANSI/ASHRAE/IES Standard 90.1-2004 commercial code. However, not all building types and sizes are covered by the AEDGs. According to the LEED Reference Guide for Building Design and Construction2, the following building types and sizes are eligible for this option:
Small to Medium Office buildings up to 100,000 ft2 (9 290 m2) Medium to Large Retail buildings up to 100,000 ft2 (9 290 m2) K-12 School buildings up to 200,000 ft2 (18 580 m2)
Warehouse and Distribution Center buildings up to 500,000 ft2 (46 450 m2) Therefore, among the given options, only the school project is eligible to pursue this option, as it falls within the size limit for the K-12 School AEDG3.

QUESTION: 90

A project has a potable water source as well as two alternative water sources.
Which of the following statements is applicable for a project using two alternative water sources?

A project may not use two alternative water sources
Target the uses that require the least treatment first
Match uses by location: indoor sources to indoor uses, outdoor sources to outdoor uses
All alternative water sources should be treated to potable water standards

Answer(s): B

Explanation:

The best practice for using alternative water sources is to target the uses that require the least treatment first, such as irrigation, toilet flushing, and cooling tower makeup. This reduces the energy and cost associated with treating water to higher standards than necessary. Matching uses by location is not a requirement, nor is treating all alternative water sources to potable water standards. A project may use more than one alternative water source as long as they meet the applicable codes and standards.

QUESTION: 91

The LEED project has a main entrance and two service entrances in an alley behind the building.
Which entrances need non-smoking signage and at what maximum distance from the door(s) can the non-smoking signage be posted?

At the main entrance, 10 ft. (3 m) from the door
At the main entrance, 25 ft. (7.5 m) from the door
At the main entrance and the two service entrances, 10 ft. (3 m) from the doors
At the main entrance and the two service entrances, 25 ft. (7.5 m) from the doors

Answer(s): C

Explanation:

According to the LEED v4 Reference Guide for Building Design and Construction, no smoking signage must be placed within 10 feet (3 meters) of every building entrance, except for alarmed emergency exits. This applies to both the main entrance and the service entrances, regardless of their location or frequency of use. The signage is intended to communicate the no-smoking policy to occupants and visitors and prevent environmental tobacco smoke from entering the building.

QUESTION: 92

A school wants to incorporate natural daylighting in classrooms on all sides of the building.
What can the project design team explain to the school district about how this strategy will affect the operational energy cost?

Heat gain will reduce the air conditioning load
Having the lights off reduces the electricity use
Reduction in lighting fixture use reduces re-lamping
There would be passive solar heating benefits to all of the classrooms

Answer(s): B

Explanation:

Natural daylighting can reduce the electricity use for artificial lighting, which is one of the major components of operational energy cost for buildings. By having the lights off or dimmed when sufficient daylight is available, the project can save energy and money. The other options are not necessarily true or relevant for natural daylighting. Heat gain and passive solar heating depend on the orientation, shading, and insulation of the windows, not just the amount of daylight. Reduction in lighting fixture use may reduce re-lamping, but that is not a significant factor in operational energy cost compared to electricity use.
