occurs when body temperatures are held within narrow ranges, skin moisture is low and the body effort at temperature regulation is minimized
THERMAL COMFORT
Four environmental conditions
- AIR TEMPERATURE
- RELATIVE HUMIDITY
- AIR MOVEMENT
- MEAN RADIANT TEMPERATURE
- determines the rate at which heat is lost in the air
- usually measured in degrees celcius, of the air surrounding the body (thermometer)
AIR TEMPERATURE
refers to the moisture content (water vapor) of the atmosphere
RELATIVE HUMIDITY
affects the heat loss rate by both convection and evaporation
AIR MOVEMENT
when MRT differs greatly from the air temperature, its effects must be considered
MEAN RADIANT TEMPERATURE
a diverse organization dedicated to advancing the arts and sciences to heating, ventilation, air conditioning and refrigiration
ASHRAE (American Society of Heating, Refrigerating and Air-conditioning Engineers)
six basic factors of thermal comfort
ENVIRONMENTAL FACTORS:
- HUMIDITY
- AIR TEMPERATURE
- RADIANT TEMPERATURE
- AIR VELOCITY
PERSONAL FACTORS:
- CLOTHING INSULATION
- METABOLIC HEAT
if a work environment has high humidity it means there is a lot of water in the air
HUMIDITY
warmth that radiates from warm objects such as the sun etc.
RADIANT TEMPERATURE
the speed at which air is moving over and individual
AIR VELOCITY
thermal insulation provided by clothing
CLOTING INSULATION
the heat released from muscle metabolism
METABOLIC HEAT
is a coating/thin layer of a material that has very low thermal conductivity
THERMAL BARRIERS
a feautre that allows the conditioning system to switch temporarily between heating and cooling
ADAPTIVE COMFORT
3 ways of adaptive comfort
- behavioral adaptation
- psysiological adaptation
- psychological adaptation
average weather or primarily a function of the sun
CLIMATE
“climate” comes form the greek word
KLIMA
an effect whereby a mass moving in a rotating system experiences a force
CORIOLIS FORCE
climatic conditions measured in localized areas near the earths surface
MICROCLIMATE
climates that are radically different from what their location would suggest
CLIMATIC ANOMALIES
climatic data tables

- CLIMATIC DESIGN PROPERTIES
- BASIC CLIMATE CONDITION
- TEMPERATURE
- HUMIDITY
-WIND - SUNSHINE
- DEGREE RAYS
huge fusion reactor in which light atoms are fused into heavier atoms
THE SUN
the vertical angle at which sun rays strike the earth
ALTITUDE ANGLE
when all the points for one day are all connected
SKY DOME
time measured by earths rotation relative to the sun
SOLAR TIME
solar site evaluation tools
- HELIODONS
- sun dials for model testing
- conceptually clear heliodons
solar responsive strategies
- building orientation
- color
- window placement
- window size
- shading
- passive solar
- solar chimney
daylighting - ventilation preheating
- active solar
- photovoltaics
