Government Green : Sustainable Retrofits Redux : #BIM #AIA #LEED
Posted by Jim Foster in BIM, Built Environment, Energy Analysis, Green, LEED on March 11, 2010
So post yesterday was how I and I am sure everyone is starting get bombarded with this message so today in my inbox from USGBC I get these stats.
- Much of the $787 billion in federal stimulus money supports green retrofits of publicly owned buildings at the local, state and federal levels.
- The federal government alone owns and operates some 500,000 buildings.
- The federal government has a 28 percent greenhouse gas reduction target for federal operations by 2020.
- 30 percent of all LEED projects are government-owned
And they are holding the USGBC 2010 Federal Summit, May 18-19 2010 in DC
Next thing I will look into are the top 10 items in sustainable retrofits. As always input welcome.
Repeat after me…Sustainable Retrofits : #BIM #AIA #LEED
Posted by Jim Foster in Adoption, BIM, Built Environment, economic trends, Energy Analysis, Green on March 10, 2010
Within the last week I have been called, e-mailed and gone out to discuss sustainable retrofits. The logic for it seems unassailable and I included some quick stats at the bottom of the posting. However, as with the rise of virtual construction this is starting to make more sense to most that this is a real economic opportunity. What’s the cause, not sure if it’s the natural progression as companies look for opportunities in this environment, a truck load of AARA and TARP funds have hit, the Clinton Climate Initiative is creating traction, or a lot of hemp wearing hippies have hit the boardroom, however I believe the first penguins have slid down the ice and the rest of the waddle / rookery / herd is starting to follow.
Additionally, more hard data points are becoming available to assist. The Empire State Building has started a massive $500 million renovation and hopes to reduce its energy cost up to 38% annually or $4.4 Million. ‘Wait, you say’ Even I know what looks like to be a 100 year payback seems insane, why spend the money.’ If you look more closely and as they point out at the website that additional improvements on already planned upgrades cost $13.2 million, so $13.2 million yields the saving and payback in less than 4 years. The Chicago Mercantile Mart and its 4.2 million SF of showrooms, offices and and tradeshow space earned LEED -EB (Existing Building) Silver. While a video of Kong climbing the Empire State could be more compelling I included the promotional video as possibly more informing.
Inside the video at about 2:05 they talk about energy modeling. I wish they included what they used to model it, but if we start talking about scenario analysis and ROI we start talking about BIM again, and various companion products like EcoTect and IES. One of the bigger points made is that the time to do these things is by piggybacking on top of already planned improvements. But from low flush toilets, to new digital controls, reglazing windows, to chiller retrofits new ROI models are inviting and this strategy/offering has to be, absolutely, be in your quiver.
Some data points I found while researching this post.
Excerpted comments from President Obama speaking at the Brookings Institute are as follows:
Speaking about AARA funds the President said “is put Americans back to work doing the work America needs done, doubling our capacity in renewable energy’
‘Clean energy projects will all be ramping up in the months ahead’
‘I’m calling on Congress to consider a new program to provide incentives for consumers who retrofit their homes to become more energy efficient, which we know creates jobs, saves money for families, and reduces the pollution that threatens our environment. And I’m proposing that we expand select Recovery Act initiatives to promote energy efficiency and clean energy jobs which have proven particularly popular and effective.’ Full Transcript Available Here
Buildings and Climate Change – Quick Stats:
- Buildings Account for 38% of CO2 emissions in the United States —more than either the transportation or industrial sectors
- Over the next 25 years, CO2 emissions from buildings are projected to grow faster than any other sector, with emissions from commercial buildings projected to grow the fastest—1.8% a year through 2030
- Buildings consume 70% of the electricity load in the U.S.
- Buildings have a lifespan of 50-100 years during which they continually consume energy and produce CO2 emissions. If half of new commercial buildings were built to use 50% less energy, it would save over 6 million metric tons of CO2 annually for the life of the buildings—the equivalent of taking more than 1 million cars off the road every year
- The U.S. population and economy are projected to grow significantly over the coming decades, increasing the need for new buildings – to meet this demand, approximately 15 million new buildings are projected to be constructed by 2015
- Building green is one of the best strategies for meeting the challenge of climate change because the technology to make substantial reductions in energy and CO2 emissions already exists. The average LEED® certified building uses 32% less electricity and saves 350 metric tons of CO2 emissions annually
- Modest investments in energy-saving and other climate-friendly technologies can yield buildings and communities that are environmentally responsible, profitable and healthier places to live and work, and that contribute to reducing CO2 emissions

3D from Photographs : #BIM #3D
Posted by Jim Foster in 3D, BIM, Built Environment on February 23, 2010
The world wants an easier way to get 3D. Photographic manipulation has been around for awhile. I remember sitting in a presentation by Yonald Chery for Mok3 which created photo immersive 3D, and this was back in 2004. The technology is still used today in something called supertour. A quote from 2004 at the time-
“This Mok3 thing could be bigger than SketchUp, especially for interior designers and architects,” Geoffrey Moore Langdon tells me. “It is like a PhotoShop that allows you to push-pull the images into correct 3D with the ease of SketchUp. Thus from a single photograph, you quickly create a 3D model:
It was ahead of its time, but we are seeing more entrants into the field. Autodesk acquired RealVIZ and its Image Modeler software, you can view a demo here. And today in the NY Times today there is the article Computers Turn Flat Photos into 3-D Buildings. Where they are using a crowd sourcing/social media aspect to data collection and improving the algorithms to stitch this stuff together. A project out of Cornell and University of Washington morphed into Microsoft’s Photosynth where you can view 3D images that have been stitched into “quasi 3D” through a browser. However, Photosynth appears to be limited by the number of photographs and data so the bigger desire was to scale this thing. So the same folks have been crunching more numbers and algorithms to create a more robust platform and a web site called Photocity was created entice people to add data and create the digital 3D construction of the WORLD, okay maybe not the world but then again…
BIM Pricing : Graphisoft fires 1st Shot of 2010
Posted by Jim Foster in BIM on February 22, 2010
So there are always been a lot of water cooler discussions about the price of software, and in here at frombulator it would be the pricing of BIM software. With visual communication of clients still being the number 1 reason for people using the stuff, and not necessarily the right reason, it seems a less robust BIM, miniBIM piece of software might do the trick. ‘Hey, that’s Sketch Up’ True Sketch Up does a fine job of communicating visually with clients, however, I don’t know anyone putting construction documents together with it, although by saying that I’m sure someone out there will correct me. However, needing a first step with BIM without laying down $5K and 20% annually seems like there might be a sweet spot for an entry product. So Graphisoft issues a press release Feb 18, about the new ArchiCAD STAR(T) Edition with a suggested retail price of $1995. Is this big enough to warrant a response from the gorilla in Waltham, yeah I know corporate HQ i in California but Revit still lives closer to its ancestral home. I will be watching this because I usually ask somewhere in my presentations, ‘When I say BIM how many of you are thinking Revit?’ Sounds like the start of good poll, not sure who wants to know the answer.
Open Standards Across Product Lines : SPie Cookbook : BIM
Posted by Jim Foster in BIM, IPD, Open Standard on February 11, 2010
Even though the initial embrace with BIM was to visually communicate with clients and initially for me was coordinated and updated documentation the real carrot is the 4D and 5D aspects of the software, and real cost estimation demands components and products that are their real world digital equivalents, not generic components. This calls for an open standard that manufactures can write and specifiers can utilize. Thankfully there are people who know this and working to make it a reality. A recent meeting sponsored by NIBS / Building Smart Alliance was held this past December to discuss and come up with a road map to reality. The Specifiers Properties Information Exchange (SPie) Meeting came up with a cookbook to address it. The fact they hope to have standards in place for all major building products by December 2010 is a great and ambitious goal. The home page to the session is available here and has other links to good information.
Excerpt
What is driving this project?
Many project stakeholders have been asking (some demanding) that building designs contain explicit properties about the objects in the building. To ensure that individual software vendors, large owners, or large manufactures do not begin to include proprietary requirements in open standard information exchanges, the SPie project was formed.
What are the next steps?
Now that the recipe for SPie has been created, NIBS is conducting an outreach effort that will result in a spring 2010 meeting. The purpose of this meeting is to allow a wide range of trade associations to engage with the project as quickly as possible. Our goal will be to have complete templates and product property data sets be available across the majority of building products by Dec 2010.
Private Cloud BIM
Posted by Jim Foster in BIM, cloud, SaaS on February 10, 2010
Excellent article from Chris France on AECBytes on how Little Diversified is using Private Cloud Computing to deliver cost savings across its organization and powerful computing to its designers.
Excerpt below but well worth the jump to read the article. And thanks to John Allsop and his blog @ http://blog.tropicalismo360.com/ for bringing this to my attention.
**********************
We have heard a lot about Cloud Computing and SaaS (Software as a Service), but what about moving our high performance graphics workstations to the cloud? This article describes how Little Diversified Architectural Consulting, located in Charlotte NC, built a private cloud that included their high performance graphics workstations (HPGW). A private cloud differs from the public cloud providers such as Amazon Web Services or Google by the fact that the cloud computing infrastructure and resources are controlled by the individual business that deploys it. (See a brief discussion by Tom Bittman of Gartner on private cloud computing in this YouTube video.)
BIM Standards
Posted by Jim Foster in BIM, IFC on February 2, 2010
While on of the benefits discussed ad nauseum about BIM is the ability to find and fix problems digitally the other is the hope of interoperability, that data will seamlessly port from one program to the next, energy analysis, to collision detection, etc. with that in mind we have the NIBS (National Institute of Building Sciences) and NBIMS (National Building Information Modeling Standard). NIBS NBIMS, kind or rolls of the tongue, like three month old jelly but it is available HERE. The reason for pushing the standard is for “the acceptance of an open data model of facilities.” The UK, has also published their own, available HERE which begs the question where is the International BIM Standard (IBIMS) because if we want to best put a lasso around this thing best to be under one big tent. Okay that’s a tremendous overuse of metaphors, and granted I have not gone over each on in detail to see where they may diverge but it would seem the manufacturers who sell globally would have a big interest in a single standard and the ability to produce an ‘object’ to one standard rather than many and that alone should push the agenda.
As for the data transportation between object we have IFCXML schema that is meant to be the open standard that will allow this, and if you want to get technical read the article from Dr. Mhamed Nour in the Journal of Information Technology in Construction (www.itcon.org), the title of the article Performance of Different of BIM/IFC Exchange Formats suggests that there is flavors within IFC itself, from a lay perspective this seems well too open.
BIM : Explode Value Engineering : #BIM #AIA #Revit
Posted by Jim Foster in 3D, BIM, Revit, ROI, Uncategorized, Virtual Construction on January 11, 2010
I am not an architect, nor do I play one on tv I simply have a small company that surveys buildings. While that may not qualify me to design one I have had the benefit of being in hundreds of buildings, surveyed them, see how they were put together, and they functioned with people in them, so with this little bit of information I feel qualified on commenting on architecture in general. And before I start I want to say that I believe architecture has the ability to transform and inspire like few other arts or disciplines because I can walk by a statue without noticing it (which I hope I don’t but were all in a hurry sometimes) but tougher still to ignore the building you are entering, or working in or even passing by, however, with that said I am unfortunately underwhelmed by most buildings I’ve been in or pass by, or have worked in. Too often we exist in a world that is value engineered, that is something has been designed to be produced as inexpensively as possible. I understand that, less expensively built; more people can afford to purchase; we all win, fine. Good in cars and televisions, unfortunate in buildings. We live in a center core, curtain wall efficiency that drains most of the fun, awe and art straight out of a building. And if you are trying to do something inexpensive, yet impressive this too can be a daunting task. But there are examples, artchitect turning shipping containers into homes comes to mind, like Adam Kalkin, Another is a home we surveyed designed by Carl Koch as part of community on Snake Hill. Now personally I thought it was fantastically ugly from the outside, looked like a box, seemed kind of cheap but as I entered the house, which still had all its original materials and finishes I was amazed how everything made sense, nothing wasted, coherent, took advantage of passive solar while providing lots of light and a great view, lines were simple, I was impressed but again this happens so seldom.
However, I have hope more and more architects are designing in 3D, even Architects who never once fired up CAD are embracing SketchUp as way to think and communicate in 3D. BIM allows design to happen digitally and with true BIM packages allows analysis and fabrication to build a building more cost effectively and real ROI metrics for making choices. Now this could be used for good rather than evil by providing hard bids on designs that were thought to cost prohibitive before, or proving new designs digitally and communicating them to developers and owners in 3D convinces them of their merit. What I hope is that ‘value engineering’ ceases to be a proxy for taking all the fun out out of a building but instead becomes part of the process that brings 3D digital design and BIM into reality and physical structures that continue to awe and inspire.
Public Beta Open in January : Capture as builts in Revit in the field: #Revit #BIM #asbuilt #laser #pplt
Posted by Jim Foster in As Builts, BIM, Built Environment, Existing Conditions, Laser BIM, Laser Scanning on December 16, 2009
We will be opening up our beta to public testing in January and we are asking for volunteers. Our product PKNail allows a user to use a hand held laser, Disto D8, and measure and build Revit models in the field. The measurements are transmitted via bluetooth to a mobile workstation which allows the user to quickly and accurately captures a building geometry and features. On board intelligence allows users to determine wall thicknesses, wall angles, toggle accuracy, attach notes to objects and more.
PKNail was developed by field surveyors and software engineers to help the AEC Community quickly and accurately capture a building’s geometry in Revit. This tool used alone of in conjunction with HDLS (High Definition Laser Scanning) can let you start any project in BIM / Revit. Proven ROI in as little as one project, and speed gains from measuring to model of over 200%.
With the majority of construction projects happening in the built environment, and in cities like Boston almost 80% done in the built environment start them in BIM and help everyone downstream.
This a powerful tool in capturing as builts in Revit and beta testers will be eligible for a substantial discount when purchasing.

BIM Deliverables and Level of Detail : #BIM #AIA
Posted by Jim Foster in BIM on December 10, 2009
The AIA issued a document last year E202 to try and put a wrapper around BIM development and the expected amount of detail needed with each deliverable. The first question most of us ask or should ask our clients is, ‘what do you need it for?’ Not to be facetious, like when my kids ask me for my car keys (they are 11, 9, and 6) but what is the purpose of the model as it goes from a simple generic model for spatial planning/validation to a complete CD Set and fine tuning that scope and managing the deliverable is still more art than science.
To break it down quickly the AIA called out 3 Levels of Details, LOD 100, 200 and 300.
LOD 100 mostly to a model built for massing and it does not mention model elements.
LOD 200 is a model built with generic model elements. And dependent on the client and deliverable you may or may not give properties to these elements.
LOD 300 is a model built with specific assemblies to the model elements, so a wall is not generally seen as ‘generic wall’ but rather an assembly such as brick | furring| dry wall with their own properties and dimensions to make a whole and this can go on all the way through the model with all the element and again should be dependent on client needs.
For most purposes I am not sure where Level 100 comes in except in the conceptual stage and most of us are dealing with LOD 200 and LOD 300 Models. The way I like to approach it is everything is a LOD 200 Model, and then speak to the client and ask what the model is to be used for and which elements need to have details and which can be generic, they sign off and then everyone has a clear idea of scope and deliverable.
When we initially starting producing BIM models in ’06 we usually made the mistake of over delivering by making custom window families for most of our projects, now with so many window libraries out there it’s pretty easy to find a facsimile and even though a 1760 Inn does not have new Andersen Double Hung Divided Light Windows they worked fine based on the client needs which was for master planning, construction of a new building, and spatial validation.
