Term
The winter season is the direct result of the following conditions:
Definition

shorter number of daylight hours

filtering effect of lower sun angles

cosine law

Term
T or F: the winter season is the direct result of planet Earth being farther from the sun
Definition
False
Term
As the vertical sun angle decreases, a given beam of sunlight will illuminate a _______ area (or unit of land) and therefore, per the same unit of land, the amount of radiation energy from this beam of sunlight _______. This is the basis of the cosine law.
Definition
Greater, decreases
Term
The heliodon and the sun-dial are devices used to study solar access and to inform solar responsive design. If you are seeking accuracy within the investigation of sunlight access on a very large design model, not a particular (reduced) area of a model, you should use the _____, because it has the largest area of accuracy for qualitative study.
Definition
Sun-dial (under sunlight)
Term
T or F: Passive Solar refers to a system that collects, stores, and redistributes solar energy with the use of fans, pumps and other electronic controls and devices.
Definition
False
Term
two elements of every passive solar heating system
Definition

"energy-storage element" (thermal mass)

"collector" (south-facing glazing)

Term

Definition
layout 1 is an example of using direct-gain and trombe-wall designs together in an effort to reduce afternoon overheating
Term
when sizing thermal mass for a direct gain system, increasing the ___________ exposed to sunlight is more beneficial than increasing the thickness of the medium.
Definition
surface area
Term
Within which climate would a trombe' wall be beneficial to the performance of a building design?

Term
A movable overhang should be used in all of the following conditions, EXCEPT when:
Definition
Passive shading is the main concern and passive heating is not required.
Term
If fossil fuels are aligned with the use of '__________' sunlight, photovoltaics generate energy from '__________' sunlight.
Definition
Ancient, Current
Term
T or F: For PV panels, the optimal orientation is due south, but there is little loss up to 34 degrees east of south or 34 degrees west of south.
Definition
False
Term
As projects are located at greater distances from the equator, they will require ____________ for effective PV mounting.
Definition
steeper pitches
Term
T or F: For temperate climates the ideal pitch angle for PV mounting is roughly equal to degrees latitude for the location.

Term
a green roof provides:
Definition

ability to reduce intensity of urban heat island

ability to reduce run-off of stormwater from your site

ability to increase the life span of roofing membrane materials

ability to reduce smog and dust in the atmosphere

Term
The double wall system was called the mur neutralisant (neutralizing wall) by Le Corbusier.

What characteristics of a double wall system validate this definition?
Definition
The double wall system acts as an acoustic and thermal buffer to the external environment.
Term
The intermediate space between the two skins of a [-----] is closed at each floor level. This is a primary difference between this system and the similar [-----] design for double-skins on buildings. 

Another system that is closed at each floor level is the [-----] but it has the added potential to create conventional rectangular (punched window) openings in the facade.
Definition

corridor facade, multi-story facade

box window, punched window
