The technical paper was published by Cristal Global—a South West company producing titanium dioxide pigment for use in paints and other products.
Rooms with high light reflectivity are thought to need less wattage and less artificial lighting time overall.
The ability for TiO2 to off-set its carbon charge when used in interior decorative paints was tested in two exercises.
In a theoretical test, the energy consumption required to light a 4x5x3m office to a standard luminescence when using paint containing 3kgs of titanium oxide, providing 80 per cent reflectivity, was found to be half of the energy required to light the same room when the paint contained 1kg of titanium oxide and provided 40 per cent reflectivity.
The energy saved by the 2kg difference would off-set the energy used to develop the TiO2 within a month and provide energy savings for more than a decade.
The second test, a practical exercise, involved a 1msq box with inter-changeable walls of various shades, containing different concentrations of TiO2, to test reflectivity.
