Q

Why does the annual horizontal solar radiation on Earth tend to decrease with rising latitude?

A

The sun rays travel further distances through the earth’s atmosphere as one moves further away from the equator

Q

Can you list 5 passive design principles that could be applied to a building located in Corvallis?

A

Rely on solar heat gains during winter
block direct sunlight during summer
daylighting optimization’s through light shelf/daylight reflector/skylight
green roof/rainwater harvesting
deciduous living wall to shade
cool the indoor environment in summer
to let daylight and solar radiations through in winter

16
Q

What is a Helidon?

A

A tool reproducing the sun path under which to test a daylighting model

17
Q

The rationale for using an artificial sky for physical daylighting model testing is

A

All of the above
The real sky is inconsistently luminous
it’s easier to avoid sunlight penetration
it provides a comfortable space for experimentation

18
Q

When implementing a daylighting strategy, which of the following is not an important consideration?

A

All of the above are important
Environmental
architectonic
human

19
Q

What do these acronyms stand for?
sDA
DF
DA

A

sDA = spatial daylight autonomy
DF = daylight factor
DA = daylight autonomy

20
Q

Effective use of daylighting in buildings can be linked to

A

All of the above
Beauty
improved academic achievement
stronger retail sales

21
Q

A north-facing window’s light shelf’s most important role in daylighting is to

A

Increases the amount of of light in the interior space

22
Q

To calculate the daylight factor at a point in room

A

Divide the interior illuminance by the exterior luminance and multiply by 100

23
Q

Can you name three types of glare?

A

Veiling glare
disability glare
discomfort glare

24
Q

A students desk in a daylit classroom will be lit by

A

All of the above
The blue or cloudy sky
reflected light from external objects
the rooms walls and ceilings

25
Q

When comparing the output of a source of a source with a color temperature of 5000K to one with a color temperature of 3500K

A

The light from the former seems colder

26
Q

What are the four main aspects covered in the European Daylight Standard?

A

Daylight provision
sunlight exposure
window view
protection from glare

27
Q

In theory, under a perfectly cloudy sky as the sun progress from its noon position to mid-afternoon

A

The daylight factor will remain constant

28
Q

What does sDA500/50% greater than or equal to 75% mean?

A

It means that 75% or more of the indoor area of interest should have an horizontal illuminance of 500 lux or more by daylight only for at least 50% of the occupied time

29
Q

What are the two main types of simulation algorithms?

A

Ray Tracing and radiosity

30
Q

Given a light source with a luminous intensity of 5 Candelas?

A

The density of its luminous flux at 1 foot is 5 fc

31
Q

You shine light on a material. 50% of it is reflected by the surface. A further 10% of the original light is absorbed by the material. What is the visible transmittance of the material?

A

40%

32
Q

Can you name the three types of light reflection?

A

Specular reflection
diffuse reflection
spread reflection

33
Q

An opaque material

A

Absorbs or reflects light

34
Q

What are the three properties of a glazing unit that you should look at when choosing one?

A

Tvis
SHGC
U-value

35
Q

A desirable light source for a daylighted art museum is?

A

The sky component

36
Q

What is the main difference between the Daylight Factor and the Daylight Autonomy?

A

DF only considers an overcast sky
DA coincides the local climate over and entire year

37
Q

For a perfectly cloudy sky

A

The distribution of light is a constant 3:1 from zenith to horizon

38
Q

Daylighting in classrooms is important because

A

Good daylighting improves learning

39
Q

What are the names of the angles that are defined in a sun path diagram?

A

Azimuth
altitude/zenith
