ATD QUIZ 2

Prevailing Winds

Amihan (Northeast Monsoon) and Habagat (Southwest Monsoon)

Amihan

Cold and Low Velocity Wind (Winter Monsoon)

October to April

Month range of Amihan

Northeast

Direction of Winter Monsoon (Amihan)

The positive (+) zone

Trade Winds

Constant winds (present throughout the year)

They are Easterly winds (winds coming from the east)

Habagat

Hot and Humid, and High Velocity Wind (Summer Monsoon)

It comes along with rain (Tagulan and Typhoons)

May to September

Month range of Habagat

Southwest

Direction of summer monsoon (Habagat)

The negative (-) zone

Trees

Wind breakers, a solution to break wind from typhoons caused by Habagat

Amihan

desirable wind for buildings

Habagat

undesirable wind and should be avoided in buildings

6:1

Ratio of roofing

West-East

Best orientation of roofing

Windward

Positive Zone (+) (Northeast), where the wind enters or originates

Leeward

Negative Zone (-) (Southwest), where the wind exits

High Pressure to Low Pressure

What happens to wind pressure if wind enters (Windward) a building (Leeward)

Windward to Leeward

Flow of Wind: From positive zone to negative zone

Awning Windows

Best window considering Tropical Design

Casement Windows

If wind is sideways, wind cannot enter this type of window because it is only open upfront

Least resistance

Wind flows through areas with what?

Screens

They offer wind resistance. Remove for Stronger wind current

Lower and Higher

Ideally, Windows in windward should be _____ and ______ on Leeward. (Hot air rises)

above and below

Hot air is always _____ and cold air stays ______

Materials Recovery Facility

MRF

Habagat (Southwest Monsoon)

MRF is an exception, it needs this type of wind

Ground Level windows

This window level works best with Tropical design. However, it is not recommended considering electrical, privacy, and child safety

Artificial Ventilation

Ventilation that requires energy

Active Ventilation

another term for artificial ventilation

2.4 meters

minimum ceiling height for atificially ventilated spaces

For faster process of cooling a space. (Lesser volume, faster cooling)

Why are standard ceiling heights lower in artificially ventilated spaces?

Heating, Ventilation, and Air Conditioning

HVAC

Window-type aircon

Cabinet-type aircon

Split-type aircon

Cassette-type aircon

Energy Efficiency Ratio (ERR)

Identifies an aircon’s rating of energy consumption (Higher rating = Lesser energy consumption)

Natural Ventilation

Ventilation that does not require energy to work

Passive Ventilation

Another term for natural ventilation

2.7 meters

minimum ceiling height for naturally ventilated spaces

Primarily to separate hot air from spaces that are accessible to users (hot air circulates upwards). Also, for better air circulation.

Why are standard ceiling heights higher in naturally ventilated spaces?

Cross-ventilation

2-opposite windows in a single space

Single-sided ventilation

smaller, larger

2 separate _______ windows (for entry and exit) are more preferrable than 1 _______ window in a single-sided ventilation

Wind Catcher (Concrete Ledge)

an exterior element that helps redirect wind into the windows.

Stack effect Ventilation

Use of hot air pressure to suction heat from the building outside through a space in the middle called the atrium.

Mostly used in high-rise buildings

Chimney Effect ventilation

Another term for Stack effect Ventilation

Courtyard Ventilation

Evaporative Cooling

Use of any forms of water through evaporation to cool the building

Roof Ventilation

Turbine Ventilator

A device that spins by using the force of the wind and utilizing that spinning motion to act on a fan that suctions hot air from the roof outside to the air.
