Question 1

Which ventilation strategy introduces outdoor air into a building without mechanical equipment by relying on wind pressure and stack effect?

Accepted Answer

Natural ventilation

Answer

Natural ventilation uses wind pressure differentials and thermal buoyancy (stack effect) to move fresh outdoor air through the building without fans or mechanical systems.

Question 2

A building's Energy Use Intensity (EUI) is expressed as:

Accepted Answer

BTUs per square foot per year

Answer

EUI is expressed in kBtu (thousand BTUs) per square foot per year and is the standard metric for comparing energy performance across buildings.

Question 3

Which water conservation strategy involves collecting rainwater from rooftops for non-potable uses such as irrigation and toilet flushing?

Accepted Answer

Rainwater harvesting

Answer

Rainwater harvesting captures precipitation from rooftops, stores it in cisterns, and treats it for reuse in non-potable applications, reducing municipal water demand.

Question 4

In sustainable construction, what is the primary benefit of using locally sourced materials?

Accepted Answer

Reduced transportation distances lower embodied carbon and support the local economy

Answer

Using locally sourced materials reduces the transportation energy and associated carbon emissions, while also supporting regional economies and businesses.

Question 5

An Energy Recovery Ventilator (ERV) differs from a Heat Recovery Ventilator (HRV) in that an ERV also transfers:

Accepted Answer

Moisture (humidity) in addition to heat

Answer

An ERV transfers both heat and moisture between incoming and outgoing airstreams, making it better suited for humid climates, while an HRV transfers heat only.
