Interview: "Design Energy Simulation for Architects" w/ Kjell Anderson, AIA

Background:
Kjell Anderson, AIA practices at LMN in Seattle, with a focus on sustainability. He previously worked at Callison, training employees internationally on energy simulation and modeling. His upcoming book, "Design Energy Simulation for Architects: Guide to 3D Graphics" explores energy use and modeling in architecture.

A five-question interview follows:

1) What was the impetus for starting the book?
After my Greenbuild 2011 presentation ("Making Better Decisions: Architect-Driven Early Design Energy Modeling") I was approached by a representative of Routledge, a UK-based publisher with an Architecture division.  My initial thought was "There's no way I'd have time to write a book while working!"  My wife supported the idea of taking time off to put it together, and so we began the adventure. 
The wider impetus is that to meet the 2030 Challenge, Architects need to be more involved in the energy performance of their buildings
The wider impetus is that to meet the 2030 Challenge, Architects need to be more involved in the energy performance of their buildings, they need to take an interest in the energy performance of their buildings, and feel responsible for the energy outcome.  There really are no guidebooks out there to help us.  There is a yawning gap between highly specialized texts that focus on mechanical performance, academic texts that perhaps give good ideas but are difficult to apply to specific projects, and graphic case studies that provide pictures but only cursory text.

My book, the AIA Energy Modeling Guide, and other sources are helping fill this gap.  Also, the emerging subculture of architects and architecture firms that engage in the energy performance of their buildings has not been exposed to the wider audience, except in magazine articles which are necessarily not in-depth.  While pools of knowledge are out there, coalescing these into a single book provides architects answers to:  What can be done?  How is it done?  How can it be interpreted and presented to inform the design process?

Over the last 50 years, architects have distanced themselves from the energy performance of their buildings, and our tools to study energy performance are very elementary.  Mechanical designers have great tools, though they can take years to properly learn.  Architectural energy-related tools are now widely available.

2) Which component of early design simulation is most in reach of today’s smaller firms and individual architects? Daylighting, air flow modeling, etc.?
Daylighting and Shading analysis are the easiest for most firms to begin to experiment with and use in their practice.  Whole-building energy analysis often requires specialists, though software is bringing this within reach of architects that have a solid building science background.

Airflow analysis almost always requires a specialist. Daylighting and Shading require some training and understanding of theory - and this training is not generally available.  Any type of simulation requires time and multiple iterations to get reasonably accurate results that can inform a building's design.  When a firm begins using simulation to inform design, there will be mistakes, so allowing for extra time and flexibility is important.

3) What was the most surprising thing you learned from the case studies? Did any hypothesis change while reviewing data?
Architects and mechanical designers, even within the same firm, often don't communicate very well or often in early design phases.  Architects seldom take the steps necessary to learn about energy performance, wanting quick, ballpark estimates to inform design - often in terms of hours.  Mechanical designers and energy analysts generally don't want to generate early options, prefering to wait until a design is complete before they investigate, and then often require weeks to produce results.  For this reasons, SOM-Chicago, HMC Architects, and many others have in-house groups that specialize in early-design simulation to bridge the gap.

.
The most surprising things about the case studies were the variety of firms engaging in the simulation of high-performance buildings [and the] inability of firms to share their modeling and data on their buildings due to NDAs.
The most surprising things about the case studies were the variety of firms engaging in the simulation of high-performance buildings, as well as the unfortunate inability of firms to share their modeling and data on their buildings due to NDAs.

I intended to write mostly about architects engaging in energy modeling of their buildings in early design, but ended up writing the Energy Modeling chapter as a guide for architects to understand the information that mechanical designers and energy analysts deal with in hopes that they will engage more meaningfully.  This can serve as a foundation for us to engage more usefully with them, as well as for architects doing some early studies themselves.

4) Given your focus on sustainability, is the profession on track for meeting the 2030 goals?
2030 is an example of a Big Hairy Audacious Goal...we don't know exactly how to get there, but we think we can.
To answer the questions literally, the way the 2030 goals are set up, new tracks have to constantly be built to reach them.  2030 is an example of a Big Hairy Audacious Goal...we don't know exactly how to get there, but we think we can.  The new tracks are being built, but not as fast as they need to be.  I am hopeful that the continued grassroots creativity and passion will continue to evolve better methods for practice, codes, and rating systems.  The first step - benchmarking and hitting the early targets - was fairly easy compared to reaching the next set of goals - 70% energy reductions and beyond.  This will require much more diligence and research on the part of architecture firms.  Most professions don't intentionally make themselves work harder for public benefit, but architects are leading the charge to create more rigorous energy codes and systems such as the 2030 Challenge, LEED and the Living Building Challenge that make our working lives more difficult, but also more fulfilling.

Another aspect is that a new generation of architects is coming into the profession that are comfortable with simulations.  They are being taught to use them to inform their designs.  Smart firms realize this and are hiring those individuals to help them transition to the new track, realizing that R&D is a relatively new thing to most firms.

5) Lastly, why do you choose to be an architect?
Architecture is grounded, creative, and spatial, a middle ground between engineering and art.  It requires inspiration and thoughtfulness.  While some days I wish I was a professional musician and didn't have to deal with building codes or budgets, the problem-solving opportunities inherent within each project can reward hard work with an elegant solution - when I can find a solution to a multifaceted problem it provides me with a great deal of satisfaction. 

Final Notes
The book is written for architects to learn about energy use, and more specifically, energy modeling, in their projects.  Early design simulation is now in the reach of most architectural firms, allowing the exploration of daylight, shading, airflow, and overall energy with in-house tools.  The book includes 30 case studies from firms such as SOM-Chicago, Miller|Hull, LMN, Lake|Flato, and many others.  It includes theory and examples of each item discussion.  It begins with an introduction to simulation, then goes through metrics from comfort to climate, and then longer chapters, highlighted with case studies, are written about shading, daylighting, airflow analysis, and energy use studies.  The final two chapters cover software in more detail, as well as how many firms set up and run in-house energy modeling programs. "Design Energy Simulation for Architects: Guide to 3D Graphics" will be published by Routledge on February 1, 2014: http://www.routledge.com/books/details/9780415840668/

No Design = No Construction, AIA|WA Testifies on the Capitol Budget

AIAWA testified in the House Capitol Budget committee yesterday regarding the broad based policy impacts of the 2010 Supplemental Capital Budget.

In this budget architects and design professionals took a disproportionally large loss, with some estimates saying that up to half of the construction/design budget was cut with the remaining dollars going toward “shovel ready” projects. The AIAWA testified to the mis-placement of design dollars noting that if buildings are not designed years in advance they can’t be built – so ultimately, if there are no design jobs there will be no construction jobs.

The AIAWA further noted our concern that the Governor is planning to transfer more money from the construction budget to put towards programs. Another cut would undeniably impact jobs in the construction/design sector. For every 10 million we spend on construction projects there are about 285 full-time jobs, with benefits, provided. New cuts could put hundreds of people out of work.

AIA|WA Testifies in Support of Design Funding in Capital Budget

The House Capital Budget Committee held its first hearing of 2010 on the Governor’s supplemental Capital Budget.

The news was not encouraging for architects, engineers and contractors who do public work. Because of lowered revenue the capital budget about $500 in the hole for the current biennium. More concerning is that the Governor is proposing to take another $157 million out of construction and put it into the state’s general fund programs.
Every $10 million dollars spent on building construction typically requires 160,000 labor hours and creates 285 full-time, family wage jobs. With private sector construction at a standstill, we need the state to protect its public construction dollars and invest them in design and construction jobs.

Also concerning is that the Governor is not proposing to rectify the inequities in the budget toward design projects. Design projects were disproportionately cut in the 2009-2011 Capital Budget. Depending on the numbers used, design was cut between 50% and 75% from the previous budget.
AIA|WA testified at the hearing to encourage lawmakers to consider the impacts of such low design funding. If design is not funded now, then construction projects will not be ready when the economy improves and there is money to be spent. Starting from scratch it takes three to four years to move a project through design to construction.
The design professions employ more than 37,000 workers with an average annual wage of $71,491 (in 2008). Total wages were $2.65 billion from 2,956 firms. However, 2008 was the height of design employment. Since August 2008, employment had dropped by more than 4,200 design workers.
This is just the direct employment of design professionals. Also affected are office support staff, consultants, interior designers, computer aided drawing (CAD) technicians, drafters, construction cost estimators and many more. Adding in these workers would multiply by many times the impact of the current recession on the industry.
AIA|WA will continue to advocate for restoration of design projects not funded in the current budget.

Your Opinion is Needed

Would a materials research lab, geared toward design professionals, be a useful resource for you? An AIA architect, the Portland Development Commission, and an extensive group of professionals in various design disciplines (architectural, industrial, apparel, etc) are working to answer that question.

A survey has been created to gauge interest for the lab amongst professionals. The AIAWA felt that making this survey available could be valuable to the profession.

The survey aims to uncover the feasibility of establishing a materials lab in the western United States. Establishment of a lab is the first step in a larger vision to develop a Creative Exchange on the west coast. The survey should only take a few minutes to complete.

Please click here for the survey (or cut and paste this address: https://lcb.qualtrics.com/SE?SID=SV_a5EXe3thMyZ1Igc&SVID=Prod)

Feel free to forward this survey to other professionals, friends, colleagues, and organizations/associations in the creative industries
