Energy Efficient Lighting

TAG | energy effficient lighting

Lux Magazine reports: When you live in a private apartment block in Edinburgh, the stairwell lighting can be like an extension of the outdoor street lights in the sense that the Edinburgh City Council pays for it. And so it is that the great British streetlight battle has gone indoors.

No, the Edinburgh City Council is not turning off the stairway lights. Rather, the Council is – you guessed it – replacing around 90,000 bulbs in thousands of the city’s so-called tenements with energy saving LEDs models, according to the Edinburgh Evening News.

The city expects the £9 million project to cut energy consumption and slash costs by 50 percent.

Edinburgh’s tenements include the historic privately owned buildings that make up a large part of the city’s distinctive housing stock, known for stone facades, high ceilings and ornamental detail. Many of them date from the 19th century; some are older, and some date up to the 1970s. Various public policies look after their heritage and maintenance.

‘Not many people realise that the council does pay for and maintain the stair lighting in all the tenements in Edinburgh and there is a need to upgrade them,’ Councillor Rickey Henderson told the paper.

The city will solicit bids. It anticipates a four-year project at a cost of about £6 million for lamps and fittings and £2.9 million for the work.

‘To get better quality and more environmentally friendly lighting we will tender for that work,’ Henderson said. ‘The investment will need to be taken out of reserves but will be put back over a period of time because the lights will be more efficient and the maintenance costs will be reduced.’

One controversy in the UK’s raging streelight debates is that LED lamps illuminate only a narrow area compared to conventional sodium lamps.

Will that be a problem in the tenement stairwells? The Edinburgh Evening News reported that:

‘Housing leaders admitted there had been concerns when street lighting was replaced with energy-efficient alternatives, amid worries urban areas were not being properly illuminated. They stressed a pilot of the proposed new service had already been carried out in six tenement stairs, with residents who completed questionnaires expressing full satisfaction.’

A pilot is one thing. This is a project in its infancy, with many more steps to climb.

Lux Magazine reports: The government is considering ways to slash demand for energy by encouraging homes and businesses to install low-energy lighting and controls.

A consultation on ways to reduce demand for electricity was launched yesterday together with the Energy Bill, and runs until the end of January.

The Department of Energy and Climate Change (DECC) believes that a quarter of the potential energy savings to be made in homes by 2030 could come from getting rid of incandescent lamps, while lighting and controls could account for more than a third of savings in commercial properties and nearly half in the public sector (including streetlighting).

In the residential sector, the major barrier to adopting these technologies is a lack of awareness, the government believes, while in commercial buildings the main problems are the payback period on lighting upgrades and the fact that the person using a building and paying the bills is not always the one with the power to make changes.

The government is considering various financial incentives for energy-efficiency measures as well as voluntary and information-based approaches.

Engineering body Cibse has welcomed the consultation, saying it comes “better late than never”. Cibse said that simple improvements to building performance could make a huge difference to the amount of energy needed in the future.

Any new measures to promote efficiency will come on top of the Green Deal, set to be launched fully in the new year, which will provide finance packages allowing  households and businesses to pay for energy-efficiency upgrades from savings on their bills.

Energy minister Ed Davey said the Energy Bill and associated measures are designed to drive low-carbon economic growth and “keep the lights on”.

Last year 39TWh of energy (that’s 39 billion kWh) was used to light commercial and public sector buildings, while around 15TWh was used in homes.
