Sustainable Retrofits Projected to be $400b US Market by 2030
Por Jim Foster - Built Environment, Green, New Technologies, Sustainable Retrofits - August 27, 2010
I had a conversation yesterday with as Program Manager from Autodesk who was looking into implementing workflows utilizing Autodesk Products to produce energy analysis for existing buildings. He had seen one of our many fantastic videos for PKNail, okay we have two homegrown videos, but our effort in capturing the built environment dovetails nicely with this effort. And while I have commented many times on the sustainable retrofit market I had not seen a number placed on it but Autodesk posted a number on their web site. If you are not intending to make the jump you can read some of their conclusions below.
Buildings are key to achieving climate stabilization, representing roughly 40% of global energy consumption and 25% of global carbon emissions. In addition, energy efficiency retrofits represent a massive latent market, projected to reach an estimated worth of $400 billion by 2030 in the U.S. alone. To respond to these twin environmental and market demands at scale and speed, the building industry needs to respond quickly and cost-effectively.
Our research suggests that rapid energy modeling enables building energy assessments with a smaller budget and shorter time frame, and can thereby help increase the number of existing buildings that undergo assessment and energy upgrades. We expect property owners and managers, home buyers, tenants and landlords, designers and architects, auditors, and energy consultants to benefit from such a workflow.
Included in this effort is Revit CEA (Conceptual Energy Analysis) that allows the user, after putting parameters in place, to use a cloud computing enironment, that is send it out for computation, to perform the calculations using Green Building Studio as the back end but making it transparent to the user. What I like about this effort is that I am not required to fire up or even know Green Building Studio to do the energy analysis, the export and data exchange, done in gbXML is done seemlessly and I get the report.
But back to the original premise which is getting existing buildings into a format that you can perform this and Autodesk has developed a workflow to help, and while this is excellent I would also argue for PKNail’s place in the workflow as measuring and building in the environment you are going to model and analyze reduces a couple of steps and amount of software you need to know. I don’t argue it should be the only tool just that it deserves a place on the shelf.
We’re Going Inside : Buildings and BIM
Por Jim Foster - 3D, Built Environment, New Technologies - August 20, 2010
New technologies have developed around the capture capture of existing buildings in a digital environment. Laser Scanning comes first to mind, and now Photofly from Autodesk, however, these seem to best address the exterior of the buildings and are used in particular circumstances that warrant them. Now comes the backpack scanner, and thanks to Erik Lewis and his blog Who’s Afraid of the Big Bad BIM for bringing it to my attention and I’ll quote him here:
“Incredible. Between PKNail and emergent technology like this, I see a real future in gathering existing facilities information into BIM databases…”

Very cool.
Autodesk taking as builts seriously : Photo Modeling and PointClouds in next release?
Por Jim Foster - Autodesk, Built Environment, New Technologies - August 16, 2010
With all the stuff flying out of Autodesk Labs recently one maybe blinded by the technology slant rather than the strategy. Looking specifically at Photofly and their new PointCloud tools with shape extraction Autodesk is putting together a strong effort in capturing the built environment within their CAD platform. Looking at the ribbon from an AutoCAD beta you can see that Photo Modeling and PointCloud are options available directly within the menu.
You can see these option on the far right, somewhat obscured by one of my feeds. Yes, my blog formatting skills still need fine tuning. Last time we researched this over 80% of construction in Boston was done within existing buildings. This new technology push with our own research dove tails nicely with the sustainable retrofit anecdotes.
I think it becomes more important that applications work within familiar platforms to not not only increase their adoption but also to incorporate into an existing workflow. Asking anyone to learn a new platform is always a tougher hill to climb and most shops are standardizing their drafting/modeling on to one or two applications.
From a technology stand point, the more tools the more better because this has been a soft spot in the whole CAD/BIM world, that is I am working in an existing building, I use Revit, I used AutoCAD, okay, now where do I start. Defining this will help everyone.
Rapid Energy Modeling : Sustainable Retrofits : The Market, Tools & Techniques : BIM
Por Jim Foster - BIM, Built Environment, Green, Laser BIM, Point to Point Laser Technology - May 19, 2010
There is a virtuous circle afoot and it’s not just how you spin social networking to acquire traffic it is sustainable retrofits and if you wonder what’s the next big thing, what gets us out of this economic tailspin, or at least malaise too many data points are starting to point in the sustainable retrofit direction. ARRA (American Relief and Recovery Act) money points that way, the President speaks about green jobs, Autodesk is hyping it and I am being constantly contacted from firms wanting to use our technology, PointKnown , to augment their green building practices. And the best thing about it, it makes sense, unlike pets.com which use to ship dogfood to you via fedex.
Here are some stats, most of them gleaned from an Autodesk Paper, (from the I read it so you don’t have to category).
-
Approximately 75 percent of buildings globally will be either new or have undergone significant renovation by 2035 (1)
-
About 150 billion square feet of existing buildings (roughly half of the entire building stock in the United States) will need to be renovated over the next 30 years. (2)
-
A recent analysis estimates that green building retrofits in the United States represent a $400B market in the next 20 years. (3)
(1) http://www.architecture2030.org/ (2009)
(2) American Institute of Architects (AIA) COTE (2009), Ecology and Design: Ecological Literacy in Architecture Education.
(3) Pike Research (2009), “Energy Efficiency Retrofits for Commercial and Public Buildings,” Executive Summary.
That means work up and down the line from surveying and modeling buildings, through energy analysis, the design process through constrcution. But the reason it makes most sense is that there is viable and real ROI not just from the environmental benefit but also from the energy savings. Autodesk’s argument, while self-serving, provides some valid points.
• Supplement energy benchmarking by providing numerous design alternatives to users.
• Democratize the energy and carbon footprinting process by making it accessible to a wider audience of practitioners.
• Make modeling faster, cheaper, and more likely to be used.
Autodesk’s work flow utilizes image modeler to be imported into Revit for modeling. While personally am not a big fan of introducing another piece of software into the workflow I can see where some people will be more comfortable using photos, etc. to create geometries. PointKnown takes a different tact in utilizing PPLT (Point to Point Technology) to define objects directly into a Revit work station. That way a user can further leverage their existing software, draft in a familiar platform, and leave with a dimensionally correct model. At the end of it you can choose to leave the generic walls, windows, etc. in place for gbXML export, or energy analysis, or begin the process into defining the elements. Your choice, but you have a dimensionally correct model in the field, with no intermediate translation step. Now to get technical PPLT is best used for planar surfaces that have minimal variation, that is a wall, that’s straight, but then again typical conditions dictate most surfaces of walls be straight or are at least intended to be. And for energy analysis this could be a powerful tool to jump start the modeling, and actually make it ‘Rapid’
Business of BIM v. Practice of BIM
Por Jim Foster - As Builts, BIM, Built Environment - May 17, 2010
I follow a discussion on LinkedIn within the BIM Experts Group titled the Politics of BIM that has provided amusement, as much as following a discussion on BIM could possibly provide, as well as being highly informative. Two of the combatants (sic. collaborators) could not reconcile their 2 positions. One was a BIM/CAD manager that coordinated very large projects, the other was a service provider for the industry. The point of the conflict? Revit. The BIM Manager did not see Revit as a robust enough program to deal with huge projects and the needed coordination between programs, etc. The service provider highlighted Revit’s abilities and Autodesk’s suite of products. What I saw was the difference between the Business of BIM and the Practice of BIM.
What I find most exciting and frustrating about the industry currently is it is wide open. The business of BIM is looking at high level needs and creating deliverables, whereas the practice of BIM is trying to coordinate large models, 4D, 5D applications etc. and getting all the disciplines to be integrated. The business and practice silos do not seem to always be to integrated and or coordinated and I can see where this causes frustration.
The BIM field is still so wide open so it is open to define in the terms of deliverables and process. For example, a Texas firm asked us for a BIM model; their only interest, as best I could decipher, was to deliver one to fulfill the Texas mandate and wanted to know little about it except for the tail light guarantee they were going to leave with their customer. I also have been asked for a Revit model by clients who have never used Revit and negotiated the contract without fully understanding what they wanted. General Contractors as the McGraw Hill SmartMarket Reports allude to and as is evidenced in the field have seemed to embrace it more quickly and understand it better and from my conversations have seen it quickly pay for itself many times over with just collision detection.
The
GSA BIM Program may be the most highly documented and while government mandates can create jobs, not sure how well they can define the process and if the industry would want them to. Meanwhile we have BIM mandates while the deliverable is still being defined. In the ideal world the industry would use a centralized BIM that gets updated during design by all the disciplines so that the owner gets a true ‘as-built’ BIM at the end of the process, however, we are still a long way from there with the majority of projects, couple with the face the majority of construction is done within the built environment. What will happen is that companies will use the parts of BIM that immediately provide value whether it is energy analysis, collision detection, scheduling or just visually communicating with the client. Those will start to grow and cross pollinate each other until we have are fully realized 3D object oriented BIM universe. Use the tools you understand, the ones that make sense for your company, improve your workflow keep an open mind and don’t let the good be the enemy of the perfect.
Government Green : Sustainable Retrofits Redux : #BIM #AIA #LEED
Por Jim Foster - BIM, Built Environment, Energy Analysis, Green, LEED - 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
Por Jim Foster - Adoption, BIM, Built Environment, Energy Analysis, Green, economic trends - 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
Por Jim Foster - 3D, BIM, Built Environment - 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…
Public Beta Open in January : Capture as builts in Revit in the field: #Revit #BIM #asbuilt #laser #pplt
Por Jim Foster - As Builts, BIM, Built Environment, Existing Conditions, Laser BIM, Laser Scanning - 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.

Revit and Rockband
Por Jim Foster - BIM, Built Environment, GSA, Revit - September 16, 2009
No the two do not have anything to do with each other but just describing my day. It started to get on the road early to get to a site an hour away where we are creating a Revit model of an existing building. The building has 5 structures inter-joined over the years with the oldest dating to 1761 and the youngest being a large addition in 1984. Multiple construction methods, floor levels, etc. make it a challenge but utilizing our PPLT (Point to Point Laser Technology) made the base model creation pretty quick, considering. I then realized I signed myself up for two engagements, one was the Boston Revit User Group meetup hosted by Shepley Bullfinch and the other other was a Tech Tuesday hosted at Microsoft’s NERD (New England Research Development) Center, clever, no?
I was impressed with the meetup group because you had a large amount of people from different companies and disciplines discussing Revit and best practices. While I was only able to stay for one of three presentations everyone was open in discussing the project and how they went about it, how to set up projects for programming and even rendering tips were coming out of the audience. I think any environment where people are freely sharing ideas a great place, and it seems Revit and BIM requires this kind of collaboration and it was refreshing. I then hustled across the river to Cambridge and the NERD center to see what was up, collect my free drink ticket and take part of the free pizza. Harmonix was there and had set up Rock Band- Beatles on the main part of the floor which was being displayed on a huge screen, I would recommend playing rock band in this format if you can swing it. Lively crew and I saw some gray beards walking around which I believe were some of the original engineers at BBN.
Also found out the first project from GSA award should be out by Friday. I feel fortunate to be part of the team that won one of the awards but its going to be interesting to see how the multi-disciplinary jigsaw puzzle is going to be put together. And got a call from Australia, at my house, from a person about PointKnown, the pencil scratched note from my wife mentioned ‘distribution.’ Saddle up.
