39
Q

Basis of design

A

Documents the reasoning and decisions made during thedesignphase of a project.

40
Q

What is closed-loop cooling?

A

A system that is designed to remove the heat inside the enclosure without letting ambient air inside it. It is the ideal solution to protect sensitive electrical equipment against dust and precipitation.

41

A site where at least 75% of the land area has been previously developed

42
Q

What is attendance boundary?

A

The limits used by school districts to determine what school students attend based on where they live

43
Q

What is commissioning?

A

Commissioning is the process of verifying
that energy systems are installed, calibrated and performing according to the owner’s project requirements, basis of design and construction documents.

44
Q

What is the 40/60 rule?

A

Project teams can determine which rating
system to use based on:

1) if the rating system is less than 40% applicable to the project, do not use
2) if the rating system is 60% or more applicable to the project, use that rating system
3) if the rating system is between 40-60% applicable to the project, the project team should assess the situation and choose appropriately

45
Q

What does the Construction Carbon Calculator measure?

A

The Construction Carbon Calculator measures the embodied carbon of the construction process.

46
Q

System that does not produce any waste product at the end by circulating the same media.

63
Q

Feedback Loop

A

The flow of information within a system that allows the system to take action.

A

Occurs when a product of a reaction leads to an increase in that reaction.

65
Q

Negative feedback loop

A

Occurs when a change brings an additional change in the opposite direction.
