CIBSE Ireland hosted a membership briefing at the Dean Hotel in Dublin recently at which Gillian Francis, CIBSE Senior Membership Officer, gave an informative presentation on grades available to candidates in CIBSE. She also detailed their options on achieving chartership through academic and experience routes.

Following the presentation the audience heard first hand from a recent MCIBSE candidate, Kevin Coleman, CIT, on his experience of gaining membership. In addition, two CIBSE interviewers – Tom Keane, PM Group and Kevin Kelly, DIT – gave a short address on what they look for from candidates at the interview stage.

The event concluded with a lively Q&A from the floor, followed by networking and informal questions over food and refreshments.

The latest edition of Ireland’s only dedicated building services research journal — SDAR Journal 2014 — was formerly introduced by Dr Brian Motherway, Chief Executive, SEAI at a ceremony held in DIT Bolton St recently.

The journal’s objective is to foster innovative practice in low-energy design of the built environment, and to encourage applied research among professional practitioners and new researchers in academia. The papers published are intended to inform design practice in construction and to assist innovative engineers striving towards optimisation of building integrated renewable technologies.

CIBSE and DIT came together four years ago to jointly publish this journal. The intention then was to disseminate insightful findings to the professional community involved in the built environment. This is still the case. The reader is taken to be a sceptic who will be convinced by evidence, not green bling on buildings, or unproven designs.

While the publishers want to hear what works well, they are conscious of the fact that the professional community can also be informed by what went wrong. Therefore they encourage critical reflection and objective evaluation of real-world projects. Post-occupancy evaluation of innovations that support more sustainable and energy-efficient practice leads to mainstreaming of good-quality, leading-edge projects.

The building services sector is data rich but sometimes time poor. SDAR Journal encourages and supports in practical terms synergies with academia. Academics are eager to support this applied research process and will provide time on task in exchange for access to useful data.

Would-be contributors are encouraged to submit abstracts for the annual SDAR Awards and Irish Lighter competitions. Both competitions are effectively feeders for this journal. The publishers particularly encourage novice researchers and industry professionals to submit short abstracts of their work, either to the above competitions or directly to the Editor.

SDAR Journal 2013 official launch

Professor Gerald Farrell, Head of School of Electrical & Electronic Engineering, gave the welcoming address with Martin Shanahan, Forfas Chief Executive, formally introducing the Journal and linking it to opportunities in the green economy.

Professor Brian Norton, DIT President, responded and then Dr Kevin Kelly, Head of School of Multidisciplinary Technologies – and SDAR Journal Editor– spoke about the contents. Dr Mike Murphy, Dean of College of Engineering and Built Environment, closed the proceedings.

The SDAR Journal is now an annual research journal published jointly by CIBSE Ireland and the School of Electrical & Electronic Engineering in DIT, with Electric Ireland as the third sponsor. Up to now, papers have been mainly by Irish authors about Irish projects. Initially, the plan was to hear about the good, the bad and the ugly of the application of low-energy projects in the built environment in Ireland.

To a large extent that is still the main objective but for next year’s edition the publishers also want to encourage more of the SDAR Journal’s many international readers to submit papers. Indeed, this current edition includes the first international papers. One is a joint paper from Belgium and the UK on demand-controlled mechanical extract ventilation system, while the other is from a world-renowned UK expert on daylighting of buildings.

SDAR Journal 2013

Kevin T. Kelly C Eng FCIBSE FSLL FIEI; President SLL; Head of School of Multidisciplinary Technologies, College of Engineering & The Built Environment, Dublin Institute of Technology.

Dear reader, welcome to the third of what has become an annual journal published by CIBSE Ireland and the School of Electrical & Electronic Engineering in DIT. This is a successful collaboration between a community of professional building services engineers with academics and researchers in the largest higher education institute in Ireland.

We will maintain a once-a-year publishing frequency while the number of entries and level of papers remains at its present rate, but we may increase the frequency of publication if the number of goodquality entries increases.

Up to now, papers have been mainly by Irish authors about Irish projects. Initially we wanted to hear about the good, the bad and the ugly of the application of low energy projects in the built environment in Ireland. The intention was to encourage applied research and postoccupancy evaluation in low energy engineering of construction projects, publish the results to disseminate insightful findings to the industry, and so help improve practice on the ground in Ireland.

To a large extent that is still our main objective but we also want to encourage more of our many international readers to submit papers. This current edition includes our first international papers. One is a joint paper from Belgium and the UK, which featured in the CIBSE Symposium in Liverpool in 2013. This might whet the appetite for the 2014 CIBSE/ASHRAE International Symposium to be held in DIT, Kevin Street Campus, Dublin, on 3/4 April 2014. The other international paper is also from the UK, from a world-renowned expert on daylighting of buildings.

If you have post-occupancy evaluation data, interesting feedback on low energy installations, or new ideas you have tried and evaluated, then please submit your proposals online to arrow.dit.ie/sdar/

All our previously-published papers are there alongside papers from the 2013 International Lighting Conference from Dublin. We would be delighted to receive your abstracts or ideas and can offer assistance and support in writing up papers.

Working engineers in industry have access to data and are often data rich and time poor, while researchers in academia are data poor but sometimes have some time for research. We in DIT will help you interrogate your data in order to publish a scholarly paper. If you would like to explore this then please contact me at kevin.kelly@dit.ie

CIBSE past-chairs dinner

The CIBSE Ireland past-chairman’s dinner was recently held in Dublin with 16 past chairs attending. Current Chairman Sean Dowd hosted the gathering which gave members of long-standing service to CIBSE Ireland a great opportunity to catch up and enjoy a very sociable night.

Apart from it being a unique gathering of so many ex chairs, the occasion was all the more special as Sean Mulcahy was presented with a Lifetime Service award after the meal.

 

Developments in Lighting in Ireland and the UK

Dr Kevin Kelly, President-Elect SLL, and Head Electrical Services Engineering, School
of Electrical Engineering Systems, DIT

In EN 12464 minimum requirements for lighting are laid down for both interior (Part 1) and exterior (Part 2) lighting. In particular, minimum values for average maintained illuminance, minimum colour rendering and maximum glare are specified. Historically, equal illuminance across the whole working plane was the goal of lighting designers. However, this is wasteful of energy because the working plane was interpreted as the whole plan area of the room.

For offices, 300/500 lux was specified, depending on whether work was mainly PC-based or paper-based. This resulted in high levels of lighting throughout the space, whether needed or not, and often for periods extending beyond the working day. These days such energy inefficiency is unacceptable.

New recommendations, such as those specified in the SLL Code for Lighting 2012, provide a pragmatic balance between adequate lighting to perform the task efficiently and quickly, and financial costs. The SLL Code for Lighting is based on quantitative recommendations that meet minimum lighting requirements, but also acknowledges there is now a need to target lighting more carefully.

Modelling of people in offices to ensure good visual interaction is now recognised as being important, and good-quality lighting and energy efficiency are now as important as quantitative specifications. Good-quality and efficient lighting in buildings also includes the need to maximise daylight penetration.

Maximising daylight offers opportunities to lift the spirit with natural light and so daylight must be carefully designed into the building, along with the artificial lighting and controls, to create good-quality and efficient lighting in a space. There is a growing consensus in industry that the way to address this challenge is to use a holistic design approach – integrating the design of the architecture, glazing and engineering design. Input is needed by the architect, structural engineer, surveyor, heating and ventilation engineer, electrical engineer, lighting designer, interior designer, control systems engineer and most importantly the client and facilities manager. 

Modern Building Information Modelling (BIM) software facilitates such a holistic approach with multidisciplinary interaction and the use of BIM is expected to grow exponentially in construction projects in the years ahead. The EU is encouraging the use of LENI, the Lighting Energy Numeric Indicator. SLL is of the view that the targets set by EN 15193 with respect to LENI are modest and is presently addressing this issue with the UK authorities in order to set more stringent targets for the UK building regulations (2013). 

Effectively, a good quality LENI will aid lighting designers to move away from installed load benchmarks to more meaningful consumption targets, and hence take account of the benefit of good quality controls. This is particularly beneficial in buildings where daylight penetration is high or where there is intermittent occupation of the building.

While standards, demands and design methodologies change, there is also major change happening in lamp technology. The development of solid state lamp technology is revolutionising lighting; with any revolution there is collateral damage and early adaptors of poor quality LED (Light Emitting Diode) lamps are among the casualties. A study by Philips Lighting (2012) estimates that while only 6% of lighting was solid state in 2010, 75% of lighting is expected to be LED lighting by 2020.

Similarly, McKinsey estimates LED lighting will be a €65 billion industry by 2020 but is more modest about the overall use at 60%. At present the biggest applications of LED lighting is for stage, external lighting, architectural lighting, retail, cold rooms, transport and hospitality. LED lamp technology is expected to impact upon office and general lighting in more interiors in the future.

To sum up, this is an exciting and challenging time for the lighting industry with huge growth potential for LED lighting and improved lighting controls generally. We are challenged to provide robust solutions that maximise the benefits of new technologies, while protecting our clients from poor-quality products and installations.

We must maximise light quality and minimise energy use by integrating daylight with appropriate artificial light in a way that lifts the spirit of those using the space and enables them to operate and override automatic lighting controls when required. We also have to ensure the reliability of products we specify and this is particularly challenging when

Dr Kevin Kelly is President Elect of the Society of Light and Lighting (SLL). He chairs the organising committee for the CIBSE/SLL International Lighting Conference scheduled for Croke Park on 12 April next. He will also make a lighting presentation in a seminar at the Energy Show in the RDS on 11 April next.

 

CIBSE and DIT at Young Scientist

Kevin Kelly pictured with JP Byrne and Cian Dowling, Causeway Comprehensive, Kerry, at the Young Scientist Competition.

DIT and CIBSE had a combined stand presence at the recent Young Scientist Competition which proved extremely successful. Apart from hundreds of young people seeking information on DIT and CIBSE, the personnel managing the stand also took time to examine projects presented by the young scientists.

A number of topical student projects caught the eye of Kevin Kelly (DIT and CIBSE). One in particular was an idea presented by JP Byrne and Cian Dowling, Causeway Comprehensive, Kerry.

In their project they linked the operation of low-cost LED lighting around the skirting board of a house so that it operated when the fire alarm activates. Kevin Kelly saw potential for further development of the concept and the intention is to feature the boys, and their extended project, in a future issue of bs news.

 

SLL Code on Lighting — 2012 Edition Now Available

Dr Kevin Kelly, DIT and Vice-President, SLL with Peter Raynham and Stephen Donohoe, DIT.

The new edition is significantly different to the 2009 edition in a number of ways. First of all the format has changed – instead of the CD format of old the 2012 version has been produced as a book. However, it is also available as a PDF download from the CIBSE Knowledge Portal (https:// www.cibseknowledgeportal.co.uk/).

The content of the Code is also significantly different and these changes were introduced for two reasons. Firstly, the SLL Handbook, which was introduced in 2009, carries a lot of material about lighting equipment and lighting design. Consequently, there was no point repeating that material in the Code.

The second major source of change was the introduction of the new CEN standard on workplace lighting (EN 12464-1:2011 Light and Lighting – Lighting of Work Places Part 1: Indoor Work Places). The recommendations in the new standard have changed in a number of ways:

– Each task now has its own uniformity requirement;

– There is now a requirement for a background illuminance in areas up to 3.5 m away from the task being performed;

– There is a requirement for illuminance on the walls and ceiling although the levels are below that recommended by the SLL;

– There is a requirement to provide a certain amount of semi-cylindrical illuminance in all spaces to make it possible for people to see each other’s faces.

A key point made more explicit in the new edition of the Code relating to requirements for indoor workplaces is that the lighting should be on the stated visual tasks. This has in fact been the case since the 2002 edition, and the term “working plane” has not been used in the Code since 1994. The latest edition of the Code takes this one step further. In the section on indoor workplaces it advises that it is wasteful of energy to light the whole space when a particular task is carried out over a relatively small area.

As well as the section on indoor workplaces, the Code also provides recommendations on “outdoor workplaces” road lighting. Thus it provides, in a single book, the performance requirement for the vast majority of lighting applications. These sections are supported by all of the necessary background information so that all the parameters discussed can be evaluated from first principals. The topics covered include:

– Basic energy and light;
– Luminous flux, intensity, illuminance, luminance and their interrelationships;
– Direct lighting;
– Indirect lighting;
– Photometric datasheets;
– Indoor lighting calculations;
– Outdoor lighting calculations;
– Measurement of lighting installations and interpreting the results;
– Colour;
– Daylight calculations;
– Predicting maintenance factor.

Given the ever-increasing pressure on lighting design to reduce the amount of energy used, there is a specific section on energy. This looks at building regulations, the CEN standard EN 15193 on lighting energy consumption, and some of the voluntary schemes such as BREAM. It also provides advice on how to provide
energy efficient lighting based on the formula of providing the right amount of light, at the right place, for the right time, using the right lighting equipment.

The Code also contains a glossary where all of the lighting terms that are used are defined. This section is based on EN 12665:2011 Light and Lighting – Basic terms and criteria for specifying lighting requirements.

To sum up, the SLL Code is a must-have reference book for anyone involved in the design of lighting. It has been written so that it complements the SLL Handbook and together the two books provide the information necessary to carry out the design of virtually all lighting schemes.
