Chapter 3 Flashcards
what are the 5 LEED categories?
1) Sustainable sites
2) Water efficiency
3) Material reduction
4) energy and atmosphere
5) indoor environmental quality
What is the triple bottom line?
People, Planet, Profit
What is Lean process improvement ?
eliminating waste in every given step of a process.
What is the life cycle approach
Financial and environmental impacts are considered over the liftime of a project.
Life cycle approach terms
Cradle-to-grave (Open):
materials are not sustainable. consumption-o-waste process.
Cradle-to-cradle (Closed):
sustainable materials. continuous loop of reuse that eliminates waste.
Upstream activites:
activities related to the extraction of raw materials used in a product
Downstream activities:
Activities related to processing materials all the way through to the delivery of the final product.
Embodied energy:
Total amount of energy used to extract materials, manufacture, transport, install and use a product through it’s useful life.
What is life-cycle costing?
Used to determine the most cost effective alternative based on the costs of the options throughout their life cycle. used to select systems, services, products that have the lowest life-cycle cost and faster payback period.
difference between stakeholders and shareholders
Stakeholders:
employees, occupants, community members, environment
Shareholders:
profits come first
What is a regenerative building?
closed systems that use only as much energy and water as it can produce.
What is a integrative process?
multidisciplinary teams collab to meet sustainable design from inception of a project to it’s completion.
“Support high-performance, cost effective project outcomes through an early analysis of the interrelationships among systems.”
3 phases on integrated process?
Discovery (predesign):
Team members in each discipline provide data relevant to the project to inform the design process. energy/water budget analysis are performed.
Implementation:
Team members compile and analyze results of research performed during discovery phase relating to system interactions b/w disciplines. Design begins to develop through the sharing of collected data.
Occupancy:
Performance assessment mechanisms are used to measure actual building performance agains expectations.
What is the iterative process?
1) conducting research and collect data within scope of work
2) sharing data
3) receiving feedback to identify synergies, waste, and savings.
4) refining the design repeatedly until all project’s sustainable goals are met.
- Takes place in tandem with integrated process.
What is systems thinking?
Look at a problem as a small part of a larger system. This makes it easier to see all interelatd parts that may contribute to or be affected by the problem = easier to solve.
What are open systems
system in which materials are resources continually enter the systems through extraction, are consumed then removed from system as waste. unsustainable.
*ie. food, water.
What are closed systems?
A cyclical system in which materials and resources are consumed and then reused or recycled. sustainable.
*ie. dead plants = fertilizer
What is a feedback loop?
Structure where data is gathered and reported in order to meet desired output. At end of one cycle around the loop, decisions are made (depending on the results) to optimize the system.
