Sustainable Thinking - 3 Major Concepts
Systems Thinking
Life-Cycle Thinking
Integrated Process
Systems Thinking can be defined as:
The understanding of each and every system of a building while also understanding their relationships and looking at the project as a whole.
Life-Cycle Approach can be defined as:
Evaluates the entire life of a project, product, or service.
Integrative Process can be defined as:
Emphasizes the importance of connection and communication among all the professionals and stakeholders in the project.
To be able to see the big picture, all the different people in the project should act as a single team.
Systems Thinking - Name the Types of Systems
Open System
Closed System
Open System
System that constantly consumes other items, uses them, and produces waste at the end.
There are no feedback loops in the open systems
Closed System
System that does not produce any waste product at the end, by circulating the same median.
In the closed systems, everything is in a loop.
Emergent Properties
Properties emerge as the result of interaction of individual elements. These are called emergent properties of the systems, and only systems can have them, not individuals.
Ex. The breathing function of the lung is the emergent property of a whole successful system.
Feedback Loops
Refers to the flow of information within a system that allows the system to take action.
Positive Feedback Loop
A producing B, which in turn produces more of A
Ex. An Interest-earning savings account. As the account grows, more interest is earned, which in turn brings further account growth.
Negative Feedback Loop
A changes brings an additional change in the opposite direction.
Ex. If a room gets warmers than the set temperature, the thermostat will send a signal to the air conditioning, and the air conditioning will stop blowing warm air.
Prius Effect
Users can respond to something only if they have real-time information about it.
Life Cycle Approach - Cradle to Grave
The practice of investigating materials from their extraction to their disposal
Life Cycle Approach - Cradle to Cradle
In order to avoid waste, closed systems should be formed, and a product should become a part of another product after its useful life through recycling or reusing. Evaluating products according to this philosophy is called a cradle to cradle approach, which aims to extend the product lifecycle to avoid waste.
Embodied Energy
To examine the environmental cost of a product to nature, the energy consumed resulting from a product’s manufacturing, transportation, installation, and use should also be evaluated.
The total energy consumed in all of these stages is called the embodied energy.
Life-Cycle Assessment (LCA)
Evaluates all the environmental effects of a product during its whole lifetime
A cradle-to grave, or cradle-to-cradle approach is used in LCA, and the total energy use and other environmental consequences resulting from the creation of that material are additionally calculated.
Life-Cycle Costing (LCC)
Assesses a product’s total cost by evaluating both its purchase prices and its operating costs.
A more expensive but more durable refrigeration system can cst less compared to a less expensive but less durable one.
Main Principles of Integrated Process
- Process Matters: The system should work efficiently.
- Start Early: The system should be active as early as possible. (preferably during the pre-design phase)
- Follow Through: The commitment should continue throughout the life of the project. It should not end with the completion of construction.
- Look beyond initial costs to long term savings: Green strategies have very short pay-back periods. And project stakeholders should be informed that their project would actually cost less in the long run.
- Include and collaborate: The professional project teams should work together with members of the community and always look at the big picture.
USGBC is the official acronym for:
U.S. Green Building Council
What is USGBC’s Mission?
” To transform the way buildings and communities are designed, built, and operated, enabling an environmentally and socially responsible, healthy, and prosperous environment that improves the quality of life.”
