Exam 11: Sustainable Sites

An urban heat island is

Buildings with white roofs use less energy in summer than similar buildings with black roofs.

An expanse of green lawn is a good choice for a sustainable site.

In a building heated by passive solar energy, it would be possible to design too wide an overhang on the south side of the building.

Passive cooling uses natural ventilation instead of mechanical air conditioning.

The greatest cost of a building is its

It is possible for a LEED-certified building to have a lower lifetime operating cost than a conventional building.

It is possible to use heat from a gas flame to produce chilled water.

The largest number of birds are killed each year by

Passive solar energy is used to pre-heat hot water.

R-value measures

A heat pump can take heat from outside air in cool weather.

One feature of green buildings is that they are easy to recognize based on architectural style.

The prerequisites in each section of LEED must be met in order to achieve LEED certification.

Daylighting uses light from windows in walls but cannot be used in roofs.

A ground source heat pump can be used for heating and cooling even in cold climates.

The same building design can provide passive heating and cooling in any climate, so that green buildings look the same whether in a desert, a tropical beach, or a temperate forest.

Night ventilation, or night flushing, works best in climates where daytime and nighttime temperatures are similar.

In winter, Earth's axis

Green roofs typically reduce energy consumption in buildings.
