A bit about me.

My name is Jose Poyan Rodriguez.

I am an undergraduate student at The University of Sheffield. I am currently (2012) in my first year doing MEng. Civil and Structural Engineering.

I have already decided to follow the structural engineering path and I have also interest in mechanical engineering and I take advance of being a student at Sheffield to study a few modules by my own.

I am Spanish and I have been living and working in London for five years before moving to Sheffield where I did the Foundation Year last term with an average mark of ninety, totalling more than six years here.

My aim is to start a career in the construction industry as early as possible.

I can be contact by email to: jpoyanrodriguez1@sheffield.ac.uk

Daylight lighting systems

Jose P.R.:

= Introduction =

With the government setting targets as early as 2016 for zero carbon homes (2019 for non-domestic Buildings) there is a need in the construction industry for reducing operational energy. After some debate, it has been agreed that zero carbon definition accounts for net carbon emissions from regulated energy devices, namely those used for space heating and cooling, water heating and lighting devices build into the house.

Whereas contractors seems to spend most of there efforts in making ultra efficient windows and wall insulation to reduce heating lose in the cold UK winters, no much effort is put in lighting. The only answer has been widespread use of saving lights, but that is not enough. Construction companies should look to natural daylight systems which are now mature and ready available technologies if they want to significantly reduce the carbon footprint.

= Daylight systems =

These devices collect natural light from the outside and deliver it deeper into the building than normal windows. They use collectors in the roof to harvest light which travels to specially designed diffusers in the rooms bringing natural light to the heart of the building where it was impossible before due to design constraints. The light is natural (without UV rays), alive and vibrant. And the diffusers can be places strategically to allow for the best distribution. There are four systems: tubular daylight device, vertical system, horizontal system, fiber optical devices.

= Tubular Daylight Devices =

Also called TDDs, these devices consist of a fixed ocular that collects light in the roof from any direction and direct it into a pipe. The interior of the pipe is lined in a high reflective surface. Light rays reflect in this surface until it reaches the diffusers placed in the rooms. This system has many advantages: it has non mechanical parts, it is relatively cheap, it can harvest low light and the pipes can be as small as 10 inches in diameter so they can be run through the walls. By contrast it requires one ocular per tube and light lose is high in tubes above 10 meters long or when the tube has a bend. That is to say it is practical to transport light up to 3 floors.

TDDs are made in UK by the Monodraught and Solatube and in the US also by Solatube. 

= Vertical Systems =

This system is very similar to TDDs, but it uses mirrors and lenses that concentrate the light previous to directing it into the pipes. A powered tracking system orients the collector towards the sun. As a result much more light can be collected compared to TDDs and can be delivered 3 to 7 times deeper into the building. However a 24 inches opening is necessary in the roof. This system is also relatively inexpensive

Vertical lighting systems are manufactured in the US by Sandolier.

= Horizontal systems =

This system uses lenses to collect natural light from the side of the windows and send it through flat light ducts above the ceiling to diffusers placed deeper into the building or in the same room. It makes use of a polymer material that combines the high reflection efficiency to total reflection with the practicality of a hollow duct. It works like a ventilation network. It is new and it has only been tested in a number of projects. It is considerable more expensive than the TDDs and Vertical Systems

Horizontal systems are made by the Canadian company SunCentralInc. 

= Fiber Optical =

Fiber optical system collect light with mirrors and lenses which track the sun and send it to the rooms through fiber optic cables. These are flexible and can be installed like electric cables, use minimal space, and can be bent in any direction, allowing to deliver light everywhere in the building. Diffusers can be replaced by point lights. But they have disadvantages: that they only harvest parallel light and they are expensive.

Fiber optical systems are made by Parans from Sweden

= Practical applications =

Cities like Sheffield in the UK, with high density of student accommodation developments in the canter, have a clear potential for these natural lighting systems. It is not difficult to see that construction companies make little use of the roof, if any, apart from the ventilation pipes. Lighting relies on windows and a clever orientation of the building, but with low external light most of the year, users tend to turn lights on most of the day.

Tubular Daylight Devices can be incorporated easily in new developments. The technology is available from UK manufacturers. Even Vertical Lighting Systems can be installed to bring zero cost natural light deeper into the building. Optical and Horizontal lighting systems which require, respectively, direct rays and panels in the facade, are, in contrast more difficult to implement.
