Retrofitting, Lighting and a Path to Net-Zero Buildings


By Miguel Aguado, Marketing & Technology Manager at Lutron According to the UK GBC1 the oldest in the

buildings


contribute 40% of the UK’s total carbon footprint, half of which derives from the energy used in buildings – clearly, the decarbonisation of our existing buildings must be the top priority.


Unintrusive, smart building technology represents one of the greatest win-win investments for governments, businesses and individuals. By embracing its benefits, we can see both cost savings and carbon reductions. Lighting, due to its ubiquity, cost saving


Efficiency – Energy efficient lighting installations can easily realise savings of more than 50% over legacy technology. However, the sensing and communication capabilities of lighting systems provides benefits that are far greater than the sum of its parts. Add presence detectors, daylight linking, timeclock events, and personal control and the impact can be upwards of an additional 60%, over the energy savings already provided by LED lighting.

smart lighting systems as the prime candidates to bring about dramatic and effective change.


Universality – Firstly, and perhaps most crucially, wherever there are buildings, there are lights. They are the most ubiquitous and intrinsic building technology, fundamental to their performance. Therefore, a single piece of legislative change could have a sweeping impact on the overall energy efficiency of our buildings. The universality of lighting must make it the clear first choice for action.

Productivity - On average, in a commercial building, energy accounts for 1% of the total


cost to the business,


while the running of the building itself accounts for 9%. The remaining 90% is devoted to the people and the accumulated knowledge


and skills that make a workforce productive.


Lighting has a greater impact on employees than any other building technology, helping productivity and overall wellbeing.
