Solar.FIN®
Architect Steve Bourne, the inventor
of Solar.fin designed this hotel to
show how the invention will look in
practice.
The façade is clear glass and the
solar.fin energy controller is behind
this, combined with normal windows.
During the day the solar.fin panels
absorb solar energy and saves it for
use as required.
At night the panels can be opened
to cool the building by radiating
heat to the night sky.
The solar.fin panel connects to the
building structure when required to
heat or cool the thermal mass of the
building.

solar.FIN: a simple leap forward in building
design
Nature is the most efficient collector of energy: A simple flower opens and
closes with the sun to collect energy. So why can’t buildings do the
same?
By simple rotation of the solar.FIN insulation collectors are either exposed
to the sun as required to gain heat. To cool the building at night again the
insulation can be opened so that the collector can be cooled by
radiating heat to the night sky.
To retain and protect the heat or cold collected the insulation is closed
The secret of the system is that the insulation always retains its integrity,
overcoming all the problems of previous systems.
Furthermore with new patented technology the solar.FIN panels can be
connected to the building structure when required either to heat or cool
the building, transferring heat or cold to the building mass which is a
natural storage medium.
Elements of the Solar.fin system.
One element only is shown for simplicity.
The key to control of the system is that the insulation (shown in green)
can rotate either exposing the collector to the sun or the night sky, or
protecting the collector from heat gain or loss.
The insulation gives the user the option to collect or dissipate heat as
required.
Plan
In section, the collector is a heat storage medium insulated from
the structure, but can be connected as required to the reinforcing
bars to transfer heat or cold to the structure. This is a patented
method and overcomes the problem of heat or cold being
transferred to the structure when it is not required.
Collection
When the sun shines the solar.fin collector heats up. Importantly the
inside of the building is protected from this heat by the insulation
which is at the rear of the collector AND between the collector and
structure. The air gap also becomes hot because of the green
house effect.
Plan
Heating
When heat is required in the building the insulation is rotated to
protect the collector from outside and to radiate the heat internally.
The second invention now is used: a connector physically joins the
collector to the reinforcement of the building so that heat is passed
into the thermal mass of the structure by conduction.
Plan
In section the patented solar.fin connector moves to make physical
contact between the collector and the steel reinforcement of the
slab so that the heat collected is conducted to the general building
thermal storage mass
Protection from over heating
During long hot periods the insulation protects the building from
overheating.
The air gap can be ventilated expelling ( or if required using ) air that
can be over 80 degrees centigrade. The collector remains cool and
can pick up excess heat from the interior or the thermal mass of the
structure.
Plan
Cooling.
The collector is warm either heated by the interior( lights equipment
and people) or purposely takes heat from the structure using the
solar.fin connector between the reinforcement and the collector.
There are now several ways the collector can dissipate the excess
heat.
Plan
Cooling by radiation
A clear night sky is a perfect receiver of radiant heat. An example of
this is in desert conditions where overnight the land can cool to
freezing point by the morning despite the very high day time
temperatures.
Plan
Cooling by ventilation
The air gap can be ventilated by opening louvers in the façade
allowing cool air in which is then heated and rises due to the stack
effect and can then be expelled outside.
By the morning the collector has been substantially cooled and it
can be connected to the reinforcing bars to conduct cool into
the thermal mass of the building. Also the collector will radiate
cool and reduce air temperatures creating natural air currents.
Patent drawing showing on the left portion heat storage and transfer. The
insulation is closed ( facing outside) so that the collector is radiating heat
inside in a way controlled by an inner insulated wall that can be vented or
opened to allow heat to the interior in a controlled way.
The right hand portion shows the insulation open so that the collector is
being heated by the sun, but the interior is still well insulated.
Plan
Left side shows transfer of heat. The right shows night cooling.
Heat transfer using connectors between the collector and the reinforcing
bars of the structure
Plan
Summary
From the diagrams it is clear that the patented solar.FIN system is able to
collect dissipate and store energy in a simple way with just two moving parts
1. Rotating lightweight insulation
2. A mechanical connection between the collector and reinforcement
• Heat or cold is collected and controlled simply and cost effectively
• Critically the building is always insulated
• The whole system can be linked to weather data so that the building not
only reacts to day to day needs but energy can be stored for future use
• All of the building methods are conventional and inexpensive.
• This makes the payback several years compared with 20+ year payback
for solar voltaic cells.
• Heating and cooling buildings is one of the major energy expenses
• The system can also incorporate all of the existing solar technology.
• The façade can be a super graphic that changes with an advertising
income that further reduces payback.
• Grants of about 20% of the cost of the system are often available
The end result is a comprehensive and cost effective solution for managing
the temperature of a building, which if combined with other systems will
make a neutral carbon footprint perfectly feasible
Patented in United States of America, Europe and China

Importantly the inside of the building is protected from this heat by the insulation which is at the rear of the collector AND between the collector and structure. The air gap also becomes hot because of the green house effect. Plan
  • 7. Heating When heat is required in the building the insulation is rotated to protect the collector from outside and to radiate the heat internally. The second invention now is used: a connector physically joins the collector to the reinforcement of the building so that heat is passed into the thermal mass of the structure by conduction. Plan
  • 8. In section the patented solar.fin connector moves to make physical contact between the collector and the steel reinforcement of the slab so that the heat collected is conducted to the general building thermal storage mass
  • 9. Protection from over heating During long hot periods the insulation protects the building from overheating. The air gap can be ventilated expelling ( or if required using ) air that can be over 80 degrees centigrade. The collector remains cool and can pick up excess heat from the interior or the thermal mass of the structure. Plan
  • 10. Cooling. The collector is warm either heated by the interior( lights equipment and people) or purposely takes heat from the structure using the solar.fin connector between the reinforcement and the collector. There are now several ways the collector can dissipate the excess heat. Plan
  • 11. Cooling by radiation A clear night sky is a perfect receiver of radiant heat. An example of this is in desert conditions where overnight the land can cool to freezing point by the morning despite the very high day time temperatures. Plan
  • 12. Cooling by ventilation The air gap can be ventilated by opening louvers in the façade allowing cool air in which is then heated and rises due to the stack effect and can then be expelled outside.
  • 13. By the morning the collector has been substantially cooled and it can be connected to the reinforcing bars to conduct cool into the thermal mass of the building. Also the collector will radiate cool and reduce air temperatures creating natural air currents.
  • 14. Patent drawing showing on the left portion heat storage and transfer. The insulation is closed ( facing outside) so that the collector is radiating heat inside in a way controlled by an inner insulated wall that can be vented or opened to allow heat to the interior in a controlled way. The right hand portion shows the insulation open so that the collector is being heated by the sun, but the interior is still well insulated. Plan
  • 15. Left side shows transfer of heat. The right shows night cooling. Heat transfer using connectors between the collector and the reinforcing bars of the structure Plan
  • 16. Summary From the diagrams it is clear that the patented solar.FIN system is able to collect dissipate and store energy in a simple way with just two moving parts 1. Rotating lightweight insulation 2. A mechanical connection between the collector and reinforcement • Heat or cold is collected and controlled simply and cost effectively • Critically the building is always insulated • The whole system can be linked to weather data so that the building not only reacts to day to day needs but energy can be stored for future use • All of the building methods are conventional and inexpensive. • This makes the payback several years compared with 20+ year payback for solar voltaic cells. • Heating and cooling buildings is one of the major energy expenses • The system can also incorporate all of the existing solar technology. • The façade can be a super graphic that changes with an advertising income that further reduces payback. • Grants of about 20% of the cost of the system are often available The end result is a comprehensive and cost effective solution for managing the temperature of a building, which if combined with other systems will make a neutral carbon footprint perfectly feasible
