Question 1

The total number of environmental impact categories in the latest version of LEED BD+C rating system, as given in this text, is

Accepted Answer

E

Question 2

The embodied energy in a building is a measure of the energy consumed

Accepted Answer

The embodied energy in a building encompasses all the energy consumed in the entire process of creating a building product, including extracting raw materials, manufacturing the product, transporting it to the site, and installing it in the building.

Question 3

Per LEED BD+C rating system, a building may receive recognition as a green building at the following levels.

Accepted Answer

The LEED BD+C rating system recognizes buildings at Certified, Silver, Gold, and Platinum levels. Therefore, option E, which includes all four levels, is the correct answer. Options A, B, and D do not include all four levels recognized by the LEED BD+C rating system. Option C includes four levels, but does not include Platinum, which is a recognized level.

Question 4

Theoretically, all materials renew in nature within 50 to 100 years.

Accepted Answer

This statement is false. While some materials, such as wood and paper, can renew within this timeframe, other materials, such as plastics and metals, can take hundreds to thousands of years to degrade in nature.

Question 5

In the process of pursuing LEED rating for a project, the role of category-Integrative Process (IP)-comes

Accepted Answer

The Integrative Process (IP) category is focused on encouraging a collaborative, holistic approach to the design and construction process of a project. This involves early engagement of all stakeholders, including the owner, design team, contractors, and occupants, to identify strategies to minimize environmental impact and improve sustainability. The IP credit requirements are most effectively achieved during the early phases of the project (schematic design and design development) and help inform decisions made throughout the entire project, including the construction phase. Therefore, the best choice is C, before or during schematic design phase.

Question 6

Which of the two products, Product A or Product B, is considered by LEED v4 to contain larger amount of recycled content? Product A has 15% pre- consumer recycled content and 35% post- consumer recycled content. Product B has 35% pre- consumer recycled content and 15% post- consumer recycled content.

Accepted Answer

LEED v4 considers post-consumer recycled content as a higher priority than pre-consumer recycled content, so Product A with 35% post-consumer recycled content is considered to have a larger amount of recycled content compared to Product B with only 15% post-consumer recycled content.

Question 7

Per LEED v4, what is the total percentage of recycled content in a product which has 20 lb of pre- consumer recycled content and 25 lb of post- consumer recycled content? The total weight of the product is 100 lb.

Accepted Answer

The answer of Per LEED v4, what is the total...

Question 8

The terms "commissioning authority" and "commissioning agent" mean the same.

Accepted Answer

Both "commissioning authority" and "commissioning agent" refer to the person or organization responsible for overseeing the commissioning process. They are often used interchangeably.

Question 9

Which of the following building materials is most renewable?

Accepted Answer

Wood is the most renewable building material as it is sourced from trees which can be replanted and regrown. Iron, natural stone, and aluminum are all finite resources that require mining and processing, causing environmental damage.

Question 10

One of the major U.S. organizations that deals with sustainable architectural design is

Accepted Answer

USGBC refers to the U.S. Green Building Council, which is a nonprofit organization that promotes sustainability in the building industry through their LEED (Leadership in Energy and Environmental Design) certification program.

Question 11

Architects generally did not consider the effect of the natural environment on buildings prior to the environmental revolution begun in the early 1970s.

Accepted Answer

Historically, architects have often considered the natural environment in their designs, incorporating elements like natural ventilation, sunlight, and materials suited to the local climate long before the environmental movement of the 1970s.

Question 12

BREEAM is a building sustainability rating system, which originated in the United Kingdom.

Accepted Answer

BREEAM (Building Research Establishment Environmental Assessment Method) was developed by the Building Research Establishment (BRE) in the UK in the 1990s and is widely used in Europe, the Middle East, and Asia.

Question 13

Which is the latest version of LEED as given in this text?

Accepted Answer

The text mentions LEED v4 as the latest version.

Question 14

Per LEED v4, a material or product is considered locally produced if all its raw materials and manufacturing takes place within

Accepted Answer

LEED v4 considers a material or product locally produced if all its raw materials and manufacturing occur within 100 miles of the construction site.

Question 15

The environmental impact category in LEED BD+C to which the greatest number of points have been assigned is

Accepted Answer

The Energy and Atmosphere category in LEED BD+C has the greatest maximum possible points (35) compared to other categories. This category includes credits related to energy efficiency, renewable energy, and greenhouse gas emissions reduction.

Question 16

The term "EPD" is an acronym for

Accepted Answer

EPD stands for Environmental Product Declarations, which provide information on a product's environmental impact throughout its life cycle.

Question 17

The total number of points assigned to all impact categories (excluding, IP, IN, and RP)in LEED v4 BD+C is

Accepted Answer

The answer of The total number of points assigned to...

Question 18

The maximum number of points a building may earn in LEED BD+C rating system is

Accepted Answer

The maximum number of points a building can earn in the LEED BD+C (Building Design + Construction) rating system is actually 110 points. This includes 100 base points, plus 10 additional points (6 for Innovation in Design and 4 for Regional Priority). None of the options provided (75, 100, 25, 50) accurately reflect this total.

Question 19

The process of commissioning of a building occurs

Accepted Answer

Commissioning of a building usually occurs during the post-construction phase, where the building systems and components are tested and verified to ensure that they function according to the design intent and meet the owner's requirements. This process includes functional performance testing, equipment calibration, and training of building operators and maintenance staff. Commissioning can also occur during the construction phase, but typically it is done after the construction is complete. Commissioning does not typically occur during the schematic design, design development, or construction document phases.

Question 20

A building that receives a total score of 55 points in the LEED- NC rating system is recognized at

Accepted Answer

A building that receives a total score of 55 points in the LEED-NC (Leadership in Energy and Environmental Design for New Construction) rating system is recognized at the Silver level. The LEED certification levels are Certified, Silver, Gold, and Platinum, with Silver typically requiring 50-59 points.
