DESIGN FACTORS
ENERGY TRANSFER AND HEAT EXPLANATION
• GENERAL
• Heat moves from warmer to cooler
• RADIANT HEAT
• Heat from the Sun or an electric radiator is Radiant Heat
• Radiant transfers through the Air & absorbs onto
surfaces it falls on.
• Surfaces have different capacities to absorb (or reflect)
heat. Dark surfaces absorb; light surfaces reflect.
• All objects radiate heat in all directions
• Warmer ones have more heat to exchange with cooler
until it balances out.
• Uncontrolled Radiant Heat is cause of discomfort;
temperature reads OK but feel overheated.
• In reverse, if surfaces not insulated then a large loss of
Radiant Heat.
Natural Home / Passive Solar Design

NATURAL HOME DESIGN TECHNIQUES
(FOR LIVING, HEALTH AND ECONOMICS)
DESIGN FACTORS
ENERGY TRANSFER AND HEAT EXPLANATION
• CONVECTION HEAT
• Air heats, expands, is lighter and rises.
• When passing over cooler objects it gives off some of its
heat, cools, contracts and falls.
• Faster air movement speeds up the Heat Exchange.
• However, if air is trapped in spaces of porous objects &
pockets, the air does not change. This is the basis of
insulation.
• CONDUCTION
• Heat transferred from molecule to molecule in a solid
material & from one material to an adjacent material.
• Metals are very conductive, wood less, gases even
lower.

ANZA VALLEY ARCHITECT
NATURAL HOME DESIGN TECHNIQUES
(FOR LIVING, HEALTH AND ECONOMICS)
DESIGN FACTORS
ENERGY TRANSFER AND HEAT EXPLANATION
• SUMMARY
• Heat Movement is calculated in the following Formula
• RADIANT HEAT + CONVECTION + CONDUCTION = TOTAL
• The total is measured in R Value which measures
Thermal Resistance, and in U Value which measures
Heat Transfer. U Value is the coefficient of R Value.
These are the same principles forming the origins of
Mechanical Systems/AC Systems designs / systems and
equipment. It is applied to the house as the Mechanical Unit
itself.

HISTORICAL PRECEDENCE
• First Homes in Caves
• Structures built into Ground or Hillsides, and/or
Structures designed for Earth on Roof for Centuries in
Many Areas of the World
THERMAL PROPERTIES
• Earth is a natural Heat Moderator
• Below frost line, Earth remains at a constant
temperature of 55 degrees F
• Even between surface and frost line Earth is the best
performing insulation.

COOL HOME for Hot Climate
FORM & LAYOUT AFFECTS COOLING
Example: Courtyard Design
(Courtyard Plants & Water add Humidity as well)
SUMMER
• Thick outer Walls & Roof keep spaces cool and Sun hits the
courtyard for short time.
• Convection Currents keep cool air pockets in smaller
rooms.
• As courtyard heats up, the cool air is drawn from the
rooms to the courtyard, creating cooling breeze effect.
• At night, heat from the courtyard roofs, stone floors cause
reverse convection, drawing heated air to the back rooms.
Also sleeping is accommodated in or near the courtyard.
WINTER
• Reverse process, and heat is left in rooms by shuttering
windows and openings to retain the heat.

COOL HOME for Hot Climate
VENTILATION
GENERAL
• Increasing air movement helps evaporation from the skin & makes one feel
fresher and active.
• Hot regions generally have winds to help cool the areas and building.
• When designing vent locations, air to enter low (cool air) and exit high (heated
air).
• Have air pass over water in dry climate; water in bowls and/or pools, and
through vegetation.

VENTILATION
Wind Scoop Idea to Generate
Winds
• Wind scoops grab upper cooler
winds at roof level. Air is
sucked down to lower floor
rooms, which pushes the
heated air out (This is assured
by high pressure at the
windward side, and low
pressure on the leeward side.
• Window screens or lattice also
used to reduce direct Sunlight.

THERMAL STACK EFFECT
Induces Ventilation & Cooling
• Works like convection with passive solar heating elements
in place, like sunspaces and solar windows.
• Passive Solar when Heating, the space is radiated.
• Passive Solar when Cooling, is the reverse. The Heat is
allowed out at the top of the space, and the Cold Air is
drawn from below.
• Thermal Mass materials keep the process working.
• The example home in the poster is this process. The
central stair has open treads to allow the “chimney” effect
allowing the air to work per the rules. The mass is the
concrete slabs at the bottom level.

RADIANT COOLING
Induces Cooling with Greenhouse Space
• The greenhouse space thermal mass elements are cooled
at night.
• Windows are opened to absorb the cool air at night.
• During the day, as the Heat rises in the space, vents at
upper levels are opened to remove the Heat.
• This also induces the cooler air flow with opening lower
vents or windows, pulling the cool air through the home to
the greenhouse space.
• The case study home is intending to use this process. The
greenhouse space will work with water mass, concrete, tile
or stone elements, and pull cool air from the north shaded
deck and under-building cooler air.
