Building Energy Collection and Storage System - with just two moving parts.    

For use on facades and roofs with the intention of collecting heat and storing it to heat the building , or radiating heat out to cool it.


Nature is the most efficient collector of energy: A flower opens and closes with the sun to collect energy. So why can't buildings do the same? The patented solar collection system emulates this simplicity with 2 moving parts to heat or cool a thermal storage medium and to then transfer this energy as required to the building’s thermal mass. The parts and materials are readily available to keep costs down so that payback periods are minimal.

The façade is clear glass and the solar energy controller is behind this. The whole system has two moving parts namely a solar collector (a rotating semi-circular insulation panel which swivels around a column with heat storage capacity) and the solar connector (from the column to the steel reinforcement of the building.) The heat storage column is insulated from the building mass so that thermal transfers occur only when required.

• By simple rotation of the solar insulation, collectors are exposed to the sun as required to gain heat.

• To cool the building at night again the insulation is opened so that the collector radiates heat to the night sky. During both these processes the insulated panel faces the interior so that excessive heat or cold in the heat storage media is shielded from the buildings users. A separate insulated internal wall can be added to control the way heat is distributed by convection or radiation. The insulated panel is rotated outwards to protect the thermal storage column in conditions of excessive heating or cooling. The secret of the system is that the insulation always retains its integrity, overcoming all the problems of previous systems. Furthermore the solar panels are connected to the building structure only when required either to heat or cool the building, transferring thermal energy through steel reinforcement to the concrete building mass, a natural heat storage medium.

Spin-offs are:-
• The system can be controlled manually or by computer linking into weather forecasts.

• There is a green house effect between the glass wall and the collector and temperatures will reach 80 deg C. This can be used directly by opening vents to the interior for instant space heating. Heat could be collected at the top of the façade or roof can be transferred using heat pumps to cool or freeze the ground.

• The stack effect in the façade will enable forced ventilation, drawing cool air from a shaded side to the heated side.

• The building will have two faces: Black when collecting or dissipating heat for maximum efficiency, and silver in heat protection mode. This change makes the facade a changing bill board with advertising revenue reducing the pay back periods.

• The solar system can be integrated with other technologies: PV systems in the glass and water heaters are both good examples.

In conclusion the solar system provides enormous opportunities; even a carbon neutral building in desert conditions where the daily weather pattern is ideal; cold at night and really hot during the day.

Primary Application of the Technology

Architecture, building, construction, energy saving

The Problem Solved by the Technology

Building's use about 30% of the world's energy. The patented solar solution with just two moving parts enables a building to be heated and cooled in a natural way almost like a flower, opening and closing to suit the prevailing weather conditions in a pro-active way. In this way the building can have a far smaller energy foot print , and can also use the by-products such as hot air in the facades because of the green house effect for laundries, slow cooking, water heating etc.

In say desert conditions where it is very hot during the day but often freezes at night we foresee that a building using the solar system would be energy self sufficient sustaining comfortable temperatures internally without additional energy inputs.

How the Technology Solves the Problem

This solar system is simple and cost effective as it uses standard building components and materials and just two simple mechanical movements. It can be manually operated or linked to a computer weather forecasting system to store energy for use as required. The building is always insulated so the amount of energy can be controlled: This has been a particular problem of most similar systems from the famous trombe wall onwards. Also and most critically the building itself acts as the thermal storage medium , and so all the energy "transactions' are as direct and efficient as possible.

Competitive Advantage

This is the first system that provides simple collection or rejection of heat directly to a thermal mass which is insulated from the building structure so it cannot over heat or over cool the building. The thermal storage is always insulated from the outside and inside. Heat or cold can be transferred into the building as required simply by connecting it to the building's steel reinforcement which is a very good conductor of heat. Furthermore the facade or roof has " two faces" and could be used for advertising substantially reducing payback times.
