We were hugely encouraged by the attendance at last week’s Faculty and would like to thank everyone again for joining us and for your patience with the spatial availability! This Faculty is number 10 in our series and more popular than ever, surprising as we had been worried that the subject matter would perhaps fail to draw much interest. We were wrong!
In preparing the content the aim was to condense the vast amount of information into a digestible half day seminar. At the same time we aimed to identify opportunities for our customers in helping to address the requirements, add value. As a secondary objective we wanted to highlight efficiencies of using the Virtual Environment suite.
Naghman and I reviewed the literature including design guides, technical memoranda, applications manuals, regulatory and voluntary requirements for the 4 main building types selected – Educational, Commercial, Healthcare and Retail.
Not surprisingly the two main areas of literature pertain to Education and Healthcare and we noted a marked difference in the ‘structure’ of the information. Healthcare is organised with an overarching set of documents driving improvement forward whereas the schools information was a bit disjointed. Having said that the Education Funding Agency has provided an overarching set of requirements upon which funding depends. However, whilst the lighting design guidance relevant for all schools has been updated to reflect the EFA requirements, the ventilation, thermal comfort and IAQ has not.
As an addendum to this there is a working group, including IES, currently looking at updating Building Bulletin 101, the EFA requirements form part of this discussion. The timeframe is as yet undecided. If the EFA requirements are extended to all new schools and major refurbishment and adopted as standard this might help to drive improvement over time.
A common theme within the EFA requirements and the Healthcare standards is Performance In Use (PIU) – the move away from ticking Design Criteria boxes during design to closing the loop between design and operation. Something very close to our heart!
As always the Faculty provided a good opportunity for like-minded individuals to get together and share ideas, we have attempted to capture some of the discussion points below;
We also had a few questions related to VE capability and application;
Due to the success of this Faculty we have decided to take the event to Glasgow on Tuesday 17th November so I look forward to seeing some of you there. You can get your free tickets here: http://ow.ly/TLsGC

This article was originally published in Building Services News Magazine. ‘Postcard from Abroad’ is a regular feature that highlights the experiences of graduate engineers from Ireland that have gone on to live and work abroad.
It is a pleasure to share my experiences abroad with you as a building services engineer who left Dublin in 2008. During the past seven years I’ve been working all over North America as a project manager and business development manager with Integrated Environmental Solutions Ltd (IES).
Many of you will be familiar with IES Ltd and IESVE software, which is used in Ireland and the UK for building performance simulation and analysis of buildings. Typical applications for using IESVE software are often necessary for new construction projects in Ireland, e.g. Part L Compliance. However, things are quite different in North America.
I graduated from DIT Bolton Street’s building services engineering course in 2006 with a 1st Class Honours Degree having come up through the diploma courses which was hugely valuable to me, even today. White Young Green (WYG) were generous enough to give me a start as a graduate building services engineer in 2006 as I had also gained valuable work-experience during the previous summer with them.
IES opened an office in Dublin in 2007 and I was keen to join with such an innovative and ever-expanding company. At the official Dublin office opening I met Dr Don McLean (IES founder and CEO) and walked away inspired by his enthusiasm for making a difference in the world by way of sustainable building design through technology.
While working in the IES Dublin office I was fortunate to work on some great consulting projects for the Office of Public Works and a few international projects too in the UK, the US, Australia and the UAE. These international projects gave me an appreciation for building performance benchmarking under different codes and standards. I also began to understand what real sustainable design meant versus making design decisions simply to play the system, or simply in order to “get the certificate”.
At IES a huge portion of our activity is driven by various energy rating systems. In North America, those rating systems can often be voluntary (eg LEED) depending on the region or building owner. You need to know your IECC / ASHRAE Standards as much as the local rating systems. This complex challenge was one of the reasons I moved to work in the IES Boston office in 2008. Six years later, I would move west again.
Settling into life in Boston
I was lucky in three areas: visa, work and accommodation. First, if you move to the US to work (outside of a J1 student visa) you will likely need either an H-1 or L-1 visa, although there are other less common options. The L-1 visa is essentially an intra-company transfer, so IES were supportive of the move. With an H-1 you could be applying to a new company, so there’s a risk involved for the employer. The one thing they have in common is the profound stress involved.
Second, with my work at IES, it was somewhat “business-as-usual” and I was performing a similar role to the one I had in our Dublin office, plus I already knew my colleagues (we are a tight-knit group at IES). Third, IES were generous enough to have a furnished apartment for me to move into. The view from my roof deck included the Massachusetts State House, the Charles River and Boston Commons.
Boston itself is a fantastic city with a large and welcoming Irish community. It is also a huge sports-centric city and there is always a Boston-based team involved in some play-offs. There are legacy neighbourhoods — the Irish are in Southie, the Italians are in the North End, there’s a Polish neighbourhood and, as always, a Chinatown.
Working in Boston was not without its challenges. There were the dreaded IP units, which at the time felt like being forced to learn how to speak Latin… why, oh why, have you not evolved? The toughest challenge was trying to convince a design team to consider something like mixed-mode ventilation, which was strangely considered a new concept.
I was shocked to learn how conservatively the New England AEC industry perceived high-performance building design. I was yearning for an equivalent to the EU’s EPBD or Ireland’s Part L. Years later, my role has evolved to encompass a much bigger region and I’ve had a chance to see how other locations embrace high performance design.
My role in North America today
Today, my region is ‘North America’. I’m not trying to be vague; below are green pins for each place I commonly work…
Yes, it is a massive geographical spread and involves a lot of travel, but that’s part of the business development challenge that IES has given me.
In my first six years in North America I was primarily focused on the East Coast, which I loved. I’ve had some interesting experiences along the way. For instance, one evening in Washington DC I went to see the White House and take in some US history. However, what I recall most clearly from that visit was looking up at one of the few snipers on the roof.
About 10 months ago I left Boston and moved west to the IES San Francisco office in order to support a new statewide compliance for building energy benchmarking. This time I moved with my girlfriend Alayne and dog Oscar. My work has mostly been focused on the west coast now, particularly in California.
The San Francisco Bay Area is still experiencing a huge tech-boom and there are constantly large volumes of people moving here. The apartment monthly rental costs are now $3,000- $5,000 (€2,750-€4,500). I feel sorry for the older locals of San Francisco who feel the artsy vibe to the city is now drowning with young techies.
It is a very different settling process on the West Coast. The time-zone difference to Ireland is now eight hours, there is a different culture to the harsh East Coast people and a different sense of humour. However, the AEC industry is an improvement. Sadly, 98% of California is currently categorised as being in “exceptional” drought, which is the worst level of drought and the worst in 163 years of record keeping.
You don’t need to convince anyone here about climate change. California has the most net-zero energy buildings in the US and there is a strict energy rating standard in place.
Earlier this year I was working with the US Navy in Honolulu. I took an opendoor helicopter tour over Pearl Harbour on my day off and got some excellent scenic photos. However, the ones that interested me most were of the endless rows of solar-panelled homes and buildings. In Hawaii, they pay $0.25- $0.33/kWh for electricity, so PV makes a lot of sense. Note: The US average is ~10-11cents/kWh. Just imagine being the odd-one-out in this neighbourhood.
Each place I go to is different and I’d sum up the US engineering culture as diverse and regional. In my day-to-day work I deal with various professionals including building physics engineers, architects, software developers, architectural engineers, contractors, energy modellers, mechanical engineers, and energy consultants. I also deal with lots of people involved in policy, from the Canadian Green Building Council to the California Energy Commission.
I’m very proud of my engineering background in Ireland and made sure to return to earn my Chartered Engineering status in 2010. I did a part-time Master’s degree in Brunel University in London during 2006-2009 but, if I’m honest, it didn’t compare to the education that DIT Bolton Street gave me.
For my B. Eng. Thesis I studied the effects of a below-ground thermal labyrinth. Then years later I was heavily involved in one for a hospital in Western Canada. Outdoor air is “bounced” through this below-ground maze, thus utilising the thermal storage of the soil and concrete to pre-heat the outdoor air in winter and pre-cool the outdoor air in summer. The tempered outdoor air is then fed into the back of two dedicated outdoor air system air handling units.
Something a lecturer in DIT, Chris Montague, said always stayed with me: “The design team won’t consider it if you don’t speak up and suggest it.” Thanks for that Chris!
My final thought
While I combine lessons from both my training in Ireland and experiences in North America, there are cases that aren’t comparable. There’s always room for comparing and contrasting the different approaches to environmental engineering and building services, and I would encourage everyone to take the differences into consideration in any decision to move abroad. Overall, I’m glad I made the move west just over seven years ago and I’m happy with the work I’m doing in the US. However, I never could have excelled as much without my training and encouragement from home and from IES.
On the build up to this year’s ASHRAE Energy Modeling conference in Atlanta, ASHRAE have launched the new Lowdown Showdown modeling challenge. ASHRAE have put together a selection of teams consisting of engineers, architects, designers and energy modelers, who will be coached by software vendors including IES, as they compete to design and model a net-zero energy building.
The challenge, which started in June, will run for 3 months on the lead up to the conference that kicks off at the end of September. Each team has been given a baseline building, which they must then work on together to create a design proposal that demonstrates net zero energy performance.
The teams will present their final design on October 1st at the ASHRAE Energy Modeling conference. The “LowDown Showdown” projects will be voted on by the conference attendees and will be judged on Energy Use Results, Creativity, Innovative Workflow and Teamwork.
I’m very excited to be working with the group that ASHRAE have assigned to the IES team. ASHRAE have given us a tricky challenge but I’m confident in the talent on the team, and that they’ll overcome and surpass expectations. Our team consists of the following members:
Ben Brannon (Arup)
Anna Osborne (Integral Group)
Greg Romanczyk (exp)
Cory Duggin (TLC Engineering for Architecture)
Shona O’Dea (DLR Group)
Megan Gunther (Affiliated Engineers, Inc.)
Scott West (Jacobs)
Andrea Costa (ACE Energy Concepts)
Even though the team is spread across a massive region, I’ve been lucky enough to meet them all before. On a personal level, they are all really wonderful people and it’s a pleasure to work with them. I’m looking forward to seeing their presentation. If you are too, we’ll see you in Atlanta on October 1st!
The conference is set to be a busy week for IES. Our team will be exhibiting our latest VE solutions and we’re hosting two pre show training workshops – HVAC Loads Sizing and Energy Modeling (http://ow.ly/QNYlk) and Advanced HVAC Modeling (http://ow.ly/QNYq3).
It doesn’t stop there. My IES colleagues Nathan and Megan will also be taking part in the following presentations, so try and check them out if you’re coming to Atlanta…
IES are also hosting a welcome reception for our customers on the Wednesday evening, September 30th – details coming soon.
So as with every release our expert team of software development, QA, and Support guys have been working extremely hard to bring you a whole host of new features that will sweep you off your feet. There’s a small difference with this year’s release though… it’s been created especially for you, our loyal customers!
We’ve taken your feedback on board over the last year and we’ve focused on refining our core applications to build upon the power and flexibility of the VE for delivering resource efficient, low-energy buildings. We understand how important it is to have competitive advantage, so with this in mind we’ve introduced a series of new exciting improvements and time saving, enhanced reporting features across our core modules.
The core applications that we’ve enhanced include, ApacheSim, MacroFlo, VE-Gaia, ModelIt, ApacheHVAC and our VE-Navigator for ASHRAE 90.1 (LEED Energy). For a more detailed list of all the new features take a look at our VE2013 New Features document.
