Question 1

What must the project team do in order to maximize the reduction in operational costs with regard to Sustainable Sites Credit, Site Improvement Plan?

AReduce lawn areas

BIncrease habitat diversity

CIncrease green space for occupants

DImprove water quality of runoff from rainwater

Answer : A

Reducing lawn areas can significantly impact operational costs related to landscaping maintenance, irrigation, and the potential need for chemical fertilizers and pesticides. By minimizing lawn areas and potentially replacing them with native or adapted vegetation, the site improvement plan can contribute to lower operational costs, water conservation, and improved site sustainability. Reference: This strategy is supported by the Sustainable Sites category in the LEED O+M Reference Guide, which encourages practices that reduce the environmental impact of landscaping and site management.

Question 2

A district energy system provides chilled and hot water to a building on a campus. What equipment must be commissioned to meet the requirements of Energy and Atmosphere Credit, Existing Building Commissioning - Analysis, Option 1. Existing Building Commissioning?

AHeat exchangers

BCentral plant chillers

CPrimary chilled water pump

DCentral plant cooling tower

Answer : A

The Energy and Atmosphere Credit, Existing Building Commissioning - Analysis, Option 1 in LEED AP O+M V4.1 requires the commissioning of major energy-using systems1. In a district energy system that provides chilled and hot water to a building, the heat exchangers play a crucial role in transferring heat between the hot and chilled water circuits.Therefore, to meet the requirements of this credit, the heat exchangers must be commissioned to ensure they are operating efficiently and effectively1.

Question 3

The decision to replace Chlorofluorocarbon (CFC) and Hydrochlorofluorocarbon (HCFC) refrigerants with alternative refrigerants

Ais straightforward because alternative refrigerants cost less to implement and operate more efficiently

Binvolves tradeoffs because alternative refrigerants are more difficult to manufacture, handle and process

Cis straightforward because alternative refrigerants such as HFC-410A have a lower Global Warming Potential
(GWP)

Dinvolves tradeoffs because alternative refrigerants may increase energy use and increase greenhouse gas emissions

Answer : D

The decision to replace Chlorofluorocarbon (CFC) and Hydrochlorofluorocarbon (HCFC) refrigerants with alternative refrigerants is not straightforward and involves tradeoffs.While alternative refrigerants like HFCs were commercialized in the 1990s as a replacement for CFCs and HCFCs, they have a strong heat-trapping effect that contributes to global warming1. Therefore, while they solve one problem (ozone layer depletion), they create another (global warming).This means that while they are alternatives, they may increase energy use and greenhouse gas emissions1.

What will replace climate warming HFCs in refrigerators and air conditioners?

HCFC and CFC phase out

What Are HFCs, and How Are They Being Regulated?

Freon One Shot C (R-422C) Refrigerant

Question 4

What information is required when adding a new space within a facility to the ENERGY STAR Portfolio Manager?

ASpace floor area and hours of operation

BNumber of workers and lighting power density

CName of utility company and 12 months of energy use data

DStatement of energy performance and carbon emissions data

Answer : A

When adding a new space within a facility to the ENERGY STAR Portfolio Manager, the required information includes the space floor area and hours of operation1.The tool helps building owners and tenants measure and track energy, water use, and waste, all in a secure online environment1.It is important to note that to receive an ENERGY STAR score in Portfolio Manager, you must enter 12 full calendar months of energy data for all energy types, in addition to complete data on property use details such as hours of operation and workers2.

Question 5

When calculating Water Efficiency Credit, Outdoor Water Use Reduction, the irrigation of athletic fields

Amust be included in the calculations

Bmust be excluded from the calculations

Cmay be included in or excluded from the calculations

Dmay be calculated using a standard 20% reduction from baseline

Answer : C

When calculating the Water Efficiency Credit for Outdoor Water Use Reduction, the irrigation of athletic fields may be included or excluded based on the project's specific circumstances and goals. This flexibility allows projects to tailor their water efficiency strategies to their unique site conditions, uses, and priorities, ensuring that the approach to outdoor water use reduction is both practical and effective. Reference: The Water Efficiency section of the LEED O+M Reference Guide provides guidance on calculating outdoor water use, offering options for including or excluding certain areas like athletic fields to meet the project's needs.

Question 6

A tenant is moving into a new space in an existing building. They will fit out this new space and are considering LEED Certification. The tenant is projecting that 80% of the space will be used as office space. They will also have 10% of the space serving as a data center supporting the office. The remaining 10% will be used as a store showcasing and selling their consumer products for direct purchase to the general public. According to the Rating System Selection

Guidance, which rating system would be most applicable for this project?

ALEED Interior Design and Construction: Retail

BLEED Operations and Maintenance: Retail

CLEED Building Design and Construction: Data Centers

DLEED Interior Design and Construction: Commercial Interiors

Answer : D

The LEED Interior Design and Construction: Commercial Interiors rating system is the most appropriate for this project.This rating system is designed for tenants leasing a portion of a larger building who want to design and construct their space to high performance standards1. The tenant's project involves fitting out a new space in an existing building, with the majority (80%) of the space being used as office space. Although there are components of retail and data center use, these do not constitute the majority of the space use. Therefore, the Commercial Interiors rating system, which is intended for office spaces and other commercial spaces, would be the most applicable.

Question 7

What credit rewards customers who change their normal consumption patterns in response to the varying price of

energy over time?

AEnergy and Atmosphere Credit, Demand Response

BEnergy and Atmosphere Credit, Ongoing Commissioning

CEnergy and Atmosphere Credit, Advanced Energy Metering

DEnergy and Atmosphere Credit, Green Power and Carbon Offsets

Answer : A

The LEED AP Operations + Maintenance (LEED AP O+M) V4.1 rewards customers who change their normal consumption patterns in response to the varying price of energy over time under the Energy and Atmosphere Credit, Demand Response. This credit encourages building owners and operators to participate in demand response programs which aim to shift the timing of energy use to off-peak periods when demand on the grid is lower. This helps to reduce the strain on the grid during peak demand periods, potentially avoiding the need for additional power plants.
