PPT 1 AND 2 Flashcards
Strategic arrangement of architectural elements in bldgs and structures to respond to specific conditions of sun, weather, and climate prevalent in the tropic region.
Horizontal lines, Equator
Latitude
Prime Meridian, Vertical Lines
Longitude
Para,eters or coordinates that help determine the location of any place on earth, measured in degrees and minutes
Latitude and Longitude
One of the two times of the year resulting in the most amount of daylight time or the least amount of daylight time in a single day (start of summer and winter)
Solstice
one of the two times of the year when the amount of daylight and nighttime hours are just about of equal length
Equinox
Two solstices every year
December and June
The region of earth surrounding the equator
Tropics
Tropics is also referred to
Tropical zone or the torrid zone
The general patttern of the tropical climate is
Warm temperatures
Moisture content of the atmpsphere “Dampness”
Humidity
(Characteristics of Tropical Climate) Temperature?
27-28 Celcious, sky temp usually higher than air temp, ground temp lower than air temp
(Characteristics of Tropical Climate)Relative humidity?
53 to 100 %
(Characteristics of Tropical Climate) Precipitation?
120-140 days of rainstorm a year
(Characteristics of Tropical Climate) Wind
Light and have long periods of still air
(Characteristics of Tropical Climate) General
high temp and high humidity create high thermal stress and encourage insect breeding

The human body maintains a thermal balance by controlling heat loss and gain
Thermal Comfort
The range of conditions under which most people feel comfortable. It is a function of a number of variables
Comfort Zone
Human comfort as determined by the ability of the body to dissipate the ehat and moisutre it produces by metabolic action
Thermal Comfort
Factors affecting thermal comfort
Air temperature, mean radiant temperature, air velocity, relative humidity
you as an architect
should design a structure than can minimize heat gain and give thermal comfort to the users
he temperature of the surrounding air, which determines the heat flow between the human body and the environment
Air temperature
a human biometeorology parameter that is used to assess the linkages between the outdoor environment and human well‐being.
Mean radiant temperature
the speed at which air is moving over an individual and is measured in meters per second (m/s).
Air velocity
In this hot and humid zone, the average temperatures are greater than 64 F (18C) year round and there is more than 59 inches of precipitation each yr
Tropical zone or the torrid zone
These climate zones are so dry because moisture is rapidly evaporated from the air and there is very little precipitation
Dry
In this zone, there are typically warm and humid summers with thunderstorms and mild winters
Temperate
Associated with large landmasses and characterized by an extreme annual range of temp
Continental
Extremely cold even in the summer, the temp never goes higher than 50 F (10c)
Polar
The measure of tthe average pattern of variation in the temp, humidity, atmospheric pressure, wind, precipitation, in a given region over long periods of time
Climate
sets of atmospheric conditions prevailing at any given place and time, it is the momentary state of the atmospheric env at a certain location
Weather
Climate of a region and/or the entire country; Basis of microclimate
Macroclimate
Climate at a regional scale
Mesoclimate
Climate of a site and its immediate environs
Microclimate
Factors that affect microclimate
Topography, Soil, Water, Vegetation, Artificial Structures
Bottom of a hollow war, air in the hollows rises upwards due to buoyancy effects
Anabatic flow
Cooler air drifting down the slope
Katabatic flow
Warm wind which blows up a steep slope or mountain side, heating of the slope, also known as upslope flow. Typically occur during the daytime in a caml sunny weather
Anabatic Wind
Wind that blows down a slope of gravity. Occurs at night, when highlanfs radiate heat and are cooled
Katabatic Wind
The difference between urban and rural temperatures
Urban-Heat-Island-Effect
Strategies related to sustaibable design practices
Passive cooling, sunshading, Thermal conductivity
