Overview
Arizona Solar
Center
Revised: 2015
Arizona is a land of physical and climatic
diversity.
From the San Francisco Peaks to the Sonoran desert, Arizonans
past and present have adapted to this land of diversity and
often to conditions of climatic intensity.
The heat of the desert summer sun and the cold of a mountain
winter have had direct impact on the form and shape of our
buildings, and the patterns of our behavior.
Living with the sun is the characteristic of a truly Arizona
architecture, not rooted in national stylistic trends but in
environmental conditions, local resources and climatic
appropriateness.
Living with the Sun - Arizona Style recognizes and uses on-site
environmental conditions to meet human needs and
comfort.
Energy and resource efficient strategies are used to optimize
comfort while minimizing environmental resource depletion,
and economic waste.
Through time there are
examples of Arizonans
Living With the Sun.
The early cliff dwelling of Montezuma’s Castle, although clearly
not designed as a solar building, is often romanticized as
Arizona’s first solar building, because it reflects solar design
principles.
Through time, Arizonans have evolved solar strategies in their
buildings and their equipment.
Passive solar water heaters were used on residential and
commercial buildings.
Both public and private desert buildings responded to the need
for shade and cross ventilation. The Yuma Hotel had
floorlength windows so beds could be pushed out on the
balcony for a cool night sleep environment.
Phoenix hotels had summer sleeping porches where rolls of
burlap were unfurled and wet down to gain an evaporative
cooling effect.
Houses were constructed with proper orientations - broad side
with windows to capture the winter sun’s warmth.
Overhangs that controlled direct impact from the high summer
sun.
The narrow sides of buildings were oriented to minimize
exposure to the intense summer east and west sun. Cooking
porches and ramadas were often provided to “keep the
kitchen heat out of the house in the summer”.
Materials such as masonry and adobe both thermal mass in
conditions where heat retention was a benefit, and a
thermal barrier where heat was desired to be excluded.
Arizona history is replete with solar applications. During the
Indian Wars, the heliograph was used as a communication
device.
The Aeneas solar pump was installed to irrigate the agricultural
lands where Tempe now stands.
Houses in northern part of the State incorporated large
porches, open and screened, as cool places for evening use
as well as sleeping.
Living With the Sun – Arizona Style continues today.
In every corner of Arizona there are solar and green buildings.
The Civano subdivision in Tucson, incorporate a variety of solar
strategies.
Today, Living With the Sun - Arizona Style can be seen in
numerous solar buildings throughout the State.
The following is a compilation of solar, renewable energy, and
green buildings that demonstrate Arizona’s rich and varied
use of the sun - Living With the Sun - Arizona Style.

# 7 Residence - Cornville, Arizona
An owner built energy efficient wood frame structure, the
living spaced are stacked above a large large rock bin within
a highly insulated enclosure directly beneath the living
spaces. The bin contains a large water tank surrounded by
rocks and two plenums (ducts).
Water, heated at roof top solar collectors, is circulated to the
tank which in turn heats the rocks surrounding it . Over the
course of the day, constant circulation heats both the tank
water and the rocks. When heating is required, floor vents at
the bottom most living space are opened and heated air
rises from the bin and up through the house.
Through “cool side” vents, cooler house air settles into the bin,
is heated and rises and repeats the process in a natural
convective loop. Hot air rises - cool air settles.
Exteriors - compact vertical form , angular shape to facilitate air
movement.

PAYSON
# 1 Residence Payson Az.
A custom solar and low resource consuming home integrated into
the site, with south facing “clearview” collector windows, thermal
mass, earth integration and berming, and extensive cross
ventilation for cooling. The Clearview collector system is a double
window system which contain an operable blind system and
interior vents (low and high) to the living spaces.
The system allows for direct solar gain into the living spaces by
simple raising of the blinds, letting sunlight in to impact the
internal thermal mass of the spaces. For more control as well as
some direct mitigation of the impact of direct solar gain, the
operable blinds are 2 colors - one side dark, the other white..
When heating is desired, the blinds are turned so the dark side
faces outward and acts as a mini- collector system, heating the air
in the double wall window cavity.
Warm air is introduced into the space by a operable vent at the
top of the window system and replacement air is introduced
at the vent at the bottom of the window system. The
circulation is natural convection with warmed air being
expelled into the living space, and cool air being drawn in
from the living space.
When protection is required to keep the spaces cool, the light
side of the blinds are turned to face outward (reflecting
unwanted solar light) and excess heat is vented to the
outside.
*Exterior - south wall glazing, clearview collector.

# 5 Roof Pond House - Phoenix,
Arizona
Built over 20 years ago, this house was the basis for a
Department of Energy demonstration of the applicability of
roof ponds for heating and cooling of buildings. This high
mass house - 6” of insulation sandwiched between 2 3”
layers of concrete structure and 12” of contained water on
the roof used the thermal absorption and release
capabilities of water to attain comfort.
The house structural elements are in fact the heating and
cooling system and replace conventional ductwork, plenums,
and mechanical heating and cooling systems.
Winter heating is achieved by exposing the roof ponds to the
daytime sun then covering them at night with movable insulation.
The warmed ponds transfer their heat through standard metal
construction decking ceilings which act as a radiator.
Summer conditions use an opposite action - Ponds are covered
during the day thereby staying cool and act as a thermal “sponge”
absorbing undesired heat from within the building and hold it
until the evening where it is disposed of through night sky
radiation, air movement convection, and evaporation by means of
gently misting the water bags.
Panels are moved by a 1/3 hp motor which runs for about 3 minutes
during the opening and closing process.
The building embodies other dessert strategies such as rough
textured walls, recessed window and door openings, cross
ventilation; an energy efficient Rumford fireplace design; low
resource fixtures and equipment, and a solar water heater.

Arizona is a land of extremes and variation. Arizonans have
adapted to, and adopted the natural conditions and
resources of Arizona sites and climate to create habitations
that are energy efficient and resource appropriate.
Throughout Arizona there are a variety of actions that have
been and are continuing to be taken by Arizonans who are
incorporating the elements of nature - the sun, wind, earth,
and water, simply and directly to meet their needs. These
actions are the basis of Living With the Sun - Arizona Style.
