Discuss US Green Building Council LEED-Green-Associate Exam Topic 6 Question 53

Which of the following demonstrates life-cycle approach to development or design?

APurchasing and demolishing a 100-year-old apartment building to build a new. energy-efficient building

BRenovating an existing building using recycled and salvaged building materials

CLocating a new building in a dense district with a diversity of uses and plentiful transit routes

DDesigning a building envelope with the most advanced technology to maximize insulation values, regardless of what materials are used

Suggested Answer: B

Renovating an existing building using recycled and salvaged building materials is an example of a life-cycle approach to development or design. A life-cycle approach is an approach that considers the environmental impacts of a product or a project from cradle to grave, or from extraction of raw materials to disposal or reuse. Renovating an existing building using recycled and salvaged building materials reduces the environmental impacts associated with new construction, such as land use change, resource depletion, energy consumption, waste generation, and greenhouse gas emissions. The LEED Green Associate Candidate Handbook states that one of the intents of the Materials and Resources category is to ''promote life-cycle assessment as a means of evaluating environmental impacts'' [1, p. 15].Reference:LEED Green Associate Candidate Handbook, [Life Cycle Assessment | U.S. Department of Energy]

I’m confused about option D. It sounds advanced, but I wonder if just focusing on technology without considering materials really aligns with the life-cycle perspective.

Danica 6 months ago

I feel like option A might not fit the life-cycle approach since it involves demolishing an old building. That seems wasteful, right?

Keena 6 months ago

I'm not sure, but I remember a practice question that emphasized sustainability. Maybe option C is also a good choice since it focuses on location and community impact?

Odelia 7 months ago

I think the life-cycle approach is about considering the entire lifespan of a building, so I’m leaning towards option B with the renovation.

Layla 7 months ago

I recall that the life-cycle approach should include sustainability, so I’m hesitant about D since it seems to prioritize technology over materials.

Deeann 7 months ago

I feel like C could also be relevant because it talks about location and mixed-use, but I’m not confident if that fits the life-cycle approach.

Johnna 7 months ago

I’m not entirely sure, but I remember a practice question that emphasized the importance of using existing resources, which makes me think B is the right choice too.

Joaquin 7 months ago

I think the life-cycle approach is about considering the entire lifespan of a building, so I’m leaning towards option B since it focuses on renovation and sustainability.
