Light-enhancing range of 'intelligent colour' paints saves significant amounts of energy 

In 2008, Dulux Trade introduced Ecosure, a range of sustainable coatings which were the product of a major research initiative with independent NGO, Forum of the Future. As part of the project, Dulux Trade created a quantifiable system to measure the environmental impact of a product throughout its life cycle. Using this research, Dulux Trade was able to formulate the Ecosure range to have up to 35% less embodied carbon and virtually no VOCs.

Although a revolutionary step for the industry, Dulux Trade continued innovating, and in July 2009 it launched Ecosure in the Light & Space colour range, which combines the environmental performance of the sustainable paint collection with the energy saving properties of Light & Space.

Light & Space is an intelligent colour range that makes a room look and feel bigger and brighter. Using a combination of unique LumitecTM technology, optimised tinting recipes and a range of High Light Reflectance Value colours, it reflects substantially more light back into and around the room. When tested by the Building Research Establishment (BRE), Light & Space delivered average energy savings of up to 22 per cent.*

The credentials of Dulux Trade Ecosure Light & Space have been put to the test at the Green House Project, an initiative run by Huntingdonshire District Council to refurbish two properties in a cost-effective and sustainable way.

The project was led by Mark Houston, Architectural Technician at the council. "Dulux Trade Ecosure Light & Space range contributed to us achieving higher levels of environmental performance. Overall, the project resulted in CO2 emissions falling by 75% and the Energy Performance Certificate (EPC) rating improving from E to B in both buildings. Collectively, the two houses also saw their energy bills decrease by £1,111 per annum."

* (This figure is based on theoretical calculations on pairs of bare rooms of dimensions 4×3×2.4 m where the light incident on all surfaces is averaged. The rooms all have the same mid-grey floor colour (LRV 50). They have a white ceiling and a colour on the walls. In one of each pair these are from the Light & Space range. In the other they are conventional products. The Light & Space and conventional colours have similar hue (colour family) and chroma (intensity of colour). The energy savings will not always equate to 22%. They will vary depending on the contents, dimensions and floor colour of the room and will differ if lighting in particular areas needs to be controlled. The calculated figure varies from 14% to 28% depending on the wall colour chosen. The actual light energy savings achieved in practice may differ from the calculations.)
