Eco LED lighting.
Warehouse's new store at Westfield, Stratford City, London at the Olympic 2012 site.
53 Degrees Ltd recently completed the installation of a new low energy Solid State LED lighting solution that is helping illuminate the new Warehouse store at Westfield Stratford City.
The new lighting system provides a greener more energy efficient solution and is been used to light up 3 large roof lights to the newly opened store. The results of using the new solid state LED lighting solutions are a dramatic 75% reduction in the headline energy usage when comparing this new lighting system to more traditional methods.
The design concept for the new Westfield store required 3 large ceiling voids to be lit-up as if they were roof-lights. The client wanted them to replicate bright daylight conditions and have the feel of light flooding into the store from outside, even though the store is situated in the middle of the Westfield Stratford shopping mall on the ground floor and has no direct external access to daylight. The 3 areas in question were built to look like they were lean-to roof lanterns. They were constructed with exposed roof rafters, acrylic was used in place of glass and it was our job to install the lighting in the ceiling void behind the acrylic to reproduce the daylight conditions required.
Key factors that needed to be considered by the design team at the design stage were;
- How to achieve the high ambient lighting levels required
- How to manage thermal build-up over the large surface areas in question.
- How to ensure energy costs were kept to minimum levels
- Ensure the lights had the correct colour rendering.
A lighting system that would address all of these issues need to be found all of which would have been a real course of concern if a conventional lighting solution was used. The traditional method of lighting up this type of installation would have been to install a grid of open frame fluorescent battens in the void behind the acrylic. The end result, even using the most efficient T5 models, would mean a total electrical load in the region of 11,000 watts. Add to this this heat dissipation issues that would have increased ventilation costs and high installations costs. Clearly, not a solution that provides the client with value for money.
Having worked on a number of similar projects the team here at 53 Degrees instantly thought a greener more cost effective solutions was available for the client that would address the above issues.
Our solution was to install a new solid state lighting system that incorporated bright white LED’s. This eco-friendly lighting solution provided the illumination required at the intensity need to replicate daylight conditions and provided a 75% reduction on energy consumption when compared to the conventional alternative. This represented a significant headline saving on the electrical running costs. Also, this type of lighting system benifits from producing far less heat, resulting in a reduction in costs for the ventilation system. Add to this the extended life expectancy and reduced maintenance factors for this type of lighting the results start to speak for themselves.
With a return on the investments expected to be achieved within the first year following installation, this solution defiantly represents value for money for the client.
The project was completed on time and to budget just before the stores grand opening in December 2012 and plays an integral part of the stores design. The light and airy feel within the store creates a relaxed, well lit shopping environment that delivers on all levels.
Not only is the lighting practical and functional, it also creates the sense of bringing a connection to the outdoors and above all, it provides a sustainable eco-friendly solutions that will reduce the carbon footprint for our client.
