A mechanical airing techniques that uses electricity, which mostly uses fossil energy that can have a negative impact on the environment and sustainability.

Describe how the human body experiences atmospheric conditions, specifically air temperature, humidity, wind and radiation.

The ratio between the actual amount of water vapour in the air and the maximum amount of water vapour that the air can hold at that air temperature, expressed as a percentage.

___________ are physical boundaries between outer space and inner space which function as protection from external environmental conditions including climate conditions.

The concept of Earth's ___________ is used to suggest that solar energy absorbed by a planet is equal to the heat

radiated from that planet.

Is the orientation of a structure in respect to seasonal changes in the sun's course as well as prevailing wind patterns.

The more heat we produce, the more heat needs to be lost.

climate of a site and its immediate environs.

a point on the earth's surface is the vertical distance it is above or below mean sea level.

Exposed sites or buildings at altitudes higher than the airport tower are likely to experience lower wind velocities

Air tends to stop moving in the same direction when it encounters an obstruction.

Air flows from low-pressure to high-pressure areas.

When the airflow is channeled and restricted, the pressure rises and the velocity increases

Sites located near large bodies of water or rivers tend to be less humid than inland areas

Land has more stable temperature than the water.

The overall measure of how much light is reflected without being absorbed when hitting an object

Stone and concrete are good heat conductors - they take a long time to heat up, but stay warmer longer

all about achieving thermal comfort through the use of passive design.

describes the human satisfactory perception of the thermal environment. It refers to a number of conditions in which the majority of people feel comfortable

the process of achieving this comfort level without the use of mechanical systems.

the first criterion to help the developer and architect examine and take advantage of thermal factors.

a natural form of wind ventilation that drives air from openings at one side of a structure through to the other.

Heat gain in tropical countries comes mostly from the walls of the building therefore, it becomes essential to insulate it properly.

This phenomenon is what results from cities that have very little greenery and many concrete surfaces. The city will have 2 to 3 degrees Celsius higher temperature than that of the surrounding suburbs and countryside.
