3. PRODUCT DESCRIPTION

Basic Uses:

The InSpire solar collector is a metal
wall system used to collect and distribute
solar-heated, outside air for ventilation or
processes, such as drying. The concept
is simple:

Integrated with HVAC

Stand Alone Destratication

· Perforated collector panels are installed
several inches from an appropriate wall,
creating an air cavity.

· Sunlight heats the solar collector surface.

· Fans create a negative pressure and draw
warmed air through the perforations
into the plenum.

· Heated air is distributed into the building
through the existing HVAC system or separate,
perforated ducts. The wall system should be
considered whenever outside air is being
heated. Energy savings depend on several
project-specic factors and can be predicted
by computer modeling. Factors that inuence
system eectiveness include the ventilation
requirement of building, length of heating
season, utility rates for heating and the
available wall area facing south, southeast or
southwest.
There are six ways to save energy:

· Solar energy is captured by the collector.

· When the fan is running, building heat loss
through the main wall is recaptured
in the plenum.

· The air space creates an insulating eect on
the building inner wall.

· In industrial buildings, solar heated air
distributed through perforated ducts
destraties and utilizes hot air trapped
at the ceiling.

· With lower ceiling temperatures in industrial
buildings, less energy is lost through ceiling
exhaust systems.

· Solar collector panels shield the inner wall
from direct sunlight during the summer season.
Typically, each square foot of solar collector
contributes 1.0 to 2.0 therms of energy per
year. Annual heating costs are usually reduced
by $1.50 to $5.50 per square foot of collector,
depending on the type of fuel replaced.
Ideal applications include:

· Industrial buildings

· Hospitals and other institutional buildings

· Schools and gymnasiums

· Arenas

· Laboratories

· Maintenance facilities

· Government and military buildings

· Warehouses

· Theaters and conference centers

· Restaurants

· Other commercial buildings
Major system components may include:

· Wall panels

· Standos and canopy components

· Fans, controls, dampers and ducting

· Trim and closures

Composition and Materials:

InSpire cladding is available in .032” aluminum
and .027” pre-weathered zinc.

Sizes and Proles:

InSpire cladding incorporates 1 ¼” high ribs.
Aluminum panels are 41 ¼” wide with 39 ⁄”
coverage, and zinc panels are
33 ⁄” wide with 31 ½” coverage.
The panels can be specied in two
orientations as illustrated. Panel lengths
are cut to customer specications up to 40’
maximum. Proles contain proprietary lanced
perforations for air intake.
The airow rate through each square foot of
collector panel is tailored to meet specic
project objectives:

· 1 to 3 cfm/ sq ft for high temperature gain

· 3 to 6 cfm/ sq ft for standard operation

· 6 to 10 cfm/ sq ft for high eciency

Color and Finish:

A choice of 30 stock colors is available in

KYNAR 500® PVDF or HYLAR® 5000 PVDF

based nishes for collector panels and accent
components. (Request color chart or chips).
Four darker colors, which absorb solar energy
more eciently, are recommended for
collector panels. A Dark Bronze anodized nish
is also available. Zinc panels have a dark, pre­weathered nish.

Limitation:

InSpire solar collector panels heat fresh air
during the day time and are not designed
to replace conventional space heating
system. InSpire must be installed over non­combustible wall material. Consult re codes
for use in multi-story applications.

4. TECHNICAL DATA

Applicable Standards

Solar Collector System

The technology for perforated solar air
heating systems was developed through
extensive testing at The National Renewable
Energy Laboratory of the U.S. Department of
Energy, and in Canada at the CANMET Energy
Diversication Research Laboratory, an agency
of Natural Resources Canada. Detailed project
performance monitoring has been conducted
under the auspices of CANMET to validate
computer feasibility software.

Environmental Considerations

The InSpire solar collector is a renewable
energy system that benets the environment
by:

- Supplying 1 to 2 therms of energy per square
foot of collector per year

- Collecting solar energy at a typical eciency
of over 60%

- Reducing annual CO2 production by
40 to 60 pounds per square foot of collector

- Utilizing metal components that contain
recycled material and are recyclable at the end
of their life cycle.
Projects with InSpire technology may qualify
for LEED® credits in renewable energy,
optimizing energy performance and other
areas.

5. Installation

InSpire cladding is generally installed 4
to 8 inches from the main wall and can
be installed over or around existing wall
openings. Installation manuals and project
specic installation drawings are available.
Contact ATAS technical service advisors for
more information. If required, additional air
distribution equipment is installed using
standard practices.

6. Availability & Cost

Availability:

The InSpire system is available through
product distributors. A complete line of
related components and trim accessories
is available to complete the wall system. In
addition, a complete line of rainware and
perimeter roof edge trims can be supplied
by ATAS to complement the wall system. Flat
sheet and/or coil stock is available in matching
color for fabrication of related components by
the installing contractor.

Cost:

Cladding cost is comparable to a brick wall.
Contact product distributors for current
pricing on system components. Many state
and federal incentives are available. The typical
payback is 3 to 8 years, sometimes 1 year or
less.

7. Warranty

Products coated with a uoropolymer, KYNAR
500® PVDF or HYLAR® 5000 PVDF nish carry a
limited warranty against chalking and fading.

8. Maintenance

InSpire collector panels are virtually
maintenance free. Surface residue may
be easily removed by conventional
cleaning methods. For painted products,
minor scratches should be touched up
with a matching paint, available from
the manufacturer. The balance of system
components contain no liquids or moving
parts, except for intake fans and dampers,
which require normal maintenance.

9. Technical Services

Complete technical information and literature
are available from ATAS International. System
design specications depend on individual
project requirements, such as the amount of
ventilation air required and the available wall
area. The ATAS technical sta may assist by
performing feasibility studies to determine
potential energy savings and dene air
collection and distribution requirements for
specic projects. ATAS will assist with design
ideas and shop drawings.
