QUESTION: 129

Several Materials and Resources credits give a bonus location valuation factor, which allows products extracted,
manufactured and produced within 100 mi. (161 km) of the project to take double valuation in credit calculations. The intent of this bonus is

to shorten construction duration by reducing shipping times
to avoid spreading products with potentially invasive non-native pests
to incentivize the purchase of products that support the local economy
to promote design with indigenous materials in order to maintain local aesthetic quality

Answer(s): C

Explanation:

The bonus location valuation factor in several Materials and Resources credits under LEED AP BD+C V4 is intended to incentivize the purchase of products that support the local economy. Products extracted, manufactured, and produced within 100 miles (161 km) of the project are valued at 200% of their cost within the calculations. This adds value to locally produced products and materials.

QUESTION: 130

The total land area within a 1/4 mi. (0.40 km) radius of a project boundary consists of 130 acres (53 hectares) and has a residential to nonresidential ratio of 60:40. Within this same total land area, there are 780 dwelling units and 1,600,000 ft2 (148 645 m2) of nonresidential building space. Given these parameters, what are the surrounding residential and nonresidential densities when attempting to achieve Location and Transportation Credit, Surrounding Density and Diverse Uses?

10 dwelling units per acre (24 dwelling units per hectare) and a Floor Area Ratio (FAR) of 0.47
10 dwelling units per acre (24 dwelling units per hectare) and a FAR of 0.70
13 dwelling units per acre (32 dwelling units per hectare) and a FAR of 0.47
15 dwelling units per acre (36 dwelling units per hectare) and a FAR of 0.70

Answer(s): C

Explanation:

The surrounding residential density is calculated by dividing the total number of dwelling units by the total residential land area. In this case, it would be 780 dwelling units divided by 60% of 130 acres, which equals approximately 13 dwelling units per acre (or 32 dwelling units per hectare). The nonresidential density, or Floor Area Ratio (FAR), is calculated by dividing the total nonresidential building floor area by the total nonresidential land area. In this case, it would be

1,600,000 ft² divided by 40% of 130 acres, which equals a FAR of approximately 0.47. These calculations are used when attempting to achieve the Location and Transportation Credit, Surrounding Density and Diverse Uses, under the LEED AP BD+C V4 rating system.

QUESTION: 131

Which of the following is required to earn Energy and Atmosphere Credit, Renewable Energy Production if using a Solar Photovoltaic System?

Carbon offsets
Daylighting strategies
Passive solar strategies
Produced electricity consumed on-site

Answer(s): D

Explanation:

The Energy and Atmosphere Credit, Renewable Energy Production rewards projects that use renewable energy systems to offset building energy costs. According to the LEED Reference Guide for Building Design and Construction, the credit has two options: Option 1. On-Site Renewable Energy and Option 2. Off-Site Renewable Energy. Option 1 requires the project to use renewable energy systems that are located on the project site and that produce electricity or thermal energy for the project. The amount of renewable energy production is calculated based on the percentage of the annual energy cost that is offset by the renewable energy systems. Option 2 requires the project to use renewable energy systems that are located off the project site and that are owned by the project or have a long-term contract with the project. The amount of renewable energy production is calculated based on the percentage of the annual energy use that is offset by the renewable energy systems.
Therefore, among the given options, only Option D is relevant to the credit requirements, as it implies that the solar photovoltaic system is located on the project site and that the produced electricity is consumed by the project. The other options, such as carbon offsets, daylighting strategies, and passive solar strategies, are not directly related to the credit requirements, although they may have other benefits for the project.

QUESTION: 132

An HVAC system consists of an air handler supplying conditioned air (mixture of return air and outdoor air) to an office, corridor, conference room and lobby. For Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance, the ventilation rate procedure calculations must be based upon what HVAC system configuration?

Single-zone system
Multiple-zone system
Mixed-mode system
100% outdoor air system

Answer(s): B

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.
