A Little Birdie Told Me

One of the core fundamentals of the design community is collaboration. Whether it be among multiple designers within a single office, or between the architect, consultants, and of course the owner working towards the goals of a project, a design is never fully visualized and constructed without careful collaboration of resources and ideas.

As individuals within that community, we constantly strive to gain more knowledge, increase our experience, and share our ideas. Design is a two-way street (sometimes a never-ending rotary), with a constant ebb and flow of concepts and diagrams. Being a singular designer isolated from the richness of team thought and continued education would result in stale work and short careers. That’s why we all attend Lightfair and IALD or AIA conferences, and go to lectures and seminars – to see what others are doing and thinking. These activities are about much more than just earning CEUs; they are also about networking and socializing, for it is these aspects that really stimulate our interests and further our careers.

Every time I attend Lightfair, I’m intrigued by the new products that are coming to market, but I’m always much more interested in, and inspired by, hearing about what others are working on, or seeing projects they have recently completed. Keeping in touch with colleagues and being a part of a community (one that’s much larger than your daily isolated focus on project-specific tasks) keeps us fresh and invigorated to strive for more or to do better work. This is not about keeping a watch on our competition – it’s about constantly seeking inspiration to enhance the built environments that we design.

Unless you’ve been under a rock lately or you still have a dial-up modem, much of this inspiration can be found online or in the palms of our hands.

For years now, we’ve turned to blogs and websites to share our ideas and to seek inspiration. It is this constant search and self-education that makes design so much fun. There are many bad answers, but there is no single right answer that solves all of our design challenges. If there were, buildings would never evolve, design would grow stagnant, and the design community would be extremely small, populated by the lucky few who first found that ‘right’ answer.

Fortunately, much of what makes design so challenging and fun is the actual process and not just the final answer. So take a minute and view some cool, thought-provoking images, reconnect with a past colleague, or listen for a clever birdie, and you may be surprised by how much out there is useful and influential.

I am certainly not one of those at the forefront of the social networking phenomenon that is upon us (I don’t even know if I am close enough to see the back of it), but I am excited by all of the endless digital media that now exist to generate the same interest, intrigue, and inspiration that I always sought, and will continue to seek, from a global design community. Sharing our ideas, listening to the experiences of others, and trying something new is what makes each of us better designers and each of our projects more successful. I haven’t seen that ‘perfect’ project yet, but I will continue to seek out ideas to improve the built environment that we all create and live in.

Season’s Energy Code Greetings

December 13, 2010 / no comments

1_seasonsgreetings_philliecasablanca.jpg

With the onset of the holiday season, we have also come to the end of the three-year energy code development season. The new 2010 version of ASHRAE/IES Standard 90.1 has been published, and IECC-2012 will be published in April 2011. (No, that’s not a typo. IECC-2012 will be published in 2011. Don’t ask, I have no idea.)

It will be a while – years, probably – before IECC-2012 is adopted by states, and at least a year before 90.1-2010 is incorporated into LEED, but the code development community is already looking towards the next versions of these model energy codes: 90.1-2013 and IECC-2015. So, while designers are currently practicing under energy codes that are at least three years old, code geeks have their heads three years in the future. So, what gifts might the next code development season bring us?

Watch the IECC

Historically, the IECC relied on 90.1 for energy code content. With IECC-2012, the IECC lighting section takes on a life of its own. Expect that trend to continue. While 90.1 will likely remain influential, since the IECC is the actual code that states adopt, the IECC may be where the action is in the future.

Stretch Your Codes

Energy codes only set a minimum acceptable performance (the worst possible building that you can legally build?). Institutions, corporations, and governments that understand this are looking for ways to push their energy use even lower. One way to do this is with “stretch codes” such as the Massachusetts Stretch Energy Code which has been adopted by over forty Massachusetts communities. This Stretch Code is an appendix to IECC-2009 that increases stringency.

Another way to go beyond the minimum is through green building codes such as the new International Green Construction Code (IGCC). Green building codes are intended to have energy performance provisions that are more stringent than base energy codes. Because of this, new energy regulation ideas are being proposed in the IGCC development process. Keeping an eye on the development of the IGCC’s energy chapter may give us an idea of what future energy codes will look like.

These advanced code programs, if adopted widely, will make the designer’s job more complex. Not only will they have to keep track of the applicable energy code in each state, but they will have to know if the municipality is using a stretch energy code or has adopted a green building code with its own separate energy provisions. And they may struggle to design to different and potentially conflicting requirements.

Squeeze Out More – a Lot More!

The pressure is on and will almost certainly continue for the energy codes to be more “efficient”. For the last code cycle, the goal was 30% more “efficient” than 90.1-2004. We don’t know what the target off of 90.1-2010/IECC-2012 will be, but I wouldn’t be surprised if we see a proposed target of 30%. Those of us who have been thinking about this don’t see how this will be possible with typical building technology, design solutions, and energy code methodology.

Lighting Power Density is currently the preeminent tool for regulating lighting energy use. The push for more efficiency in codes means pressure to lower LPDs even more. But barring an unforeseen leap in technology, we can probably only squeeze a little bit more out of LPDs if we are to maintain high-quality lighting. We may be able to eke out some more savings by expanding even further the requirements for occupancy sensors and daylight responsive controls. But how do we make big reductions – 30%, 50%, eventually all the way down to net-zero?! Daylighting.

In order to significantly reduce lighting energy use, we’re going to have to really use daylight to extensively light our buildings. If codes require this, a radical change in mindset will need to take place – resulting in major changes in building footprints, orientation, and envelope design.

Guaranteeing the Outcomes?

If energy codes are supposed to reduce building energy use, then shouldn’t we be directly regulating it? The common prescriptive code methods use blunt instruments such as LPDs, minimum equipment efficiencies, and R-values to affect how a building is designed. These methods do indirectly affect the energy use of the building, but the energy use itself (how the building is operated) is not regulated.

In an ideal world, the energy code should just tell us what the end result needs to be, and let us decide how to get there. Expect to hear more about EUI (Energy Use Intensity), measured in kBtu per square foot per year. An effective building energy performance-based code will require more robust, but easier to use, energy modeling software. It will also require a change in the way we design buildings – with a truly integrated design process where the whole design team is working together to get the most out of a limited building energy budget.

EUI may be the way to make the codes much more “efficient” and still allow high-quality buildings to be built – but many details, such as dealing with occupancy/operating hours, will have to be worked out. Look for energy codes to start requiring a building energy performance method for buildings of certain types or sizes.

Even if you perform complete energy modeling, and design to a specific annual building energy use limit, all you are doing is predicting how much energy the building will use on the day it opens, if properly commissioned and operated. Every lighting designer has their horror stories of carefully designed (and expensive!) lighting control systems that were never commissioned and/or operated correctly, leaving all the lights on, even when daylight is streaming in or when no one is around. The building meets energy code, but if it isn’t operated correctly and becomes an energy guzzler, then the code is ineffective. Realizing this, code geeks are starting to look at “outcome-based” codes.

An outcome-based code might require building owners to certify actual annual energy use. How will an outcome-based code be enforced? Will buildings someday need to get an annual energy certificate just like an elevator or health department inspection? And what would the penalties be for non-compliance? Will design professionals be held responsible for the performance of a building that they designed but do not operate?

The Gift That Keeps On Giving

As you can see, energy codes are likely to get tougher, get more complicated, and adopt unfamiliar new methods. Building design professional organizations such as the IALD, AIA, IES, and ASHRAE are all actively involved with energy code development. If you are interested in getting involved with code development and are a member of one of these organizations, you can contribute. Happy holidays!
