Washington Policy Center: green buildings get mixed results

Thursday, October 22nd, 2009

The Washington Policy Center, a conservative think-tank whose mission is to “improve lives through market solutions,” has issued a report on green buildings in the state that has less than stellar results.

However, the center is not totally a nonpartial organization. And the study, which is not even a full four

You should know better!

pages long, seems shaky to me in that references cited include articles that are not cited, single emails, and only a small handful of case studies that really don’t provide the reader with much information with which to make an informed decision. It also is very narrow in scope and only looks at a few types of projects.

Nevertheless, the points brought up in the study are of interest. The gist is that performance-based contracting in Washington State and schools that use the Washington State High Performance Schools Protocol have mixed results. Some save energy, some don’t and many have long pay back times. Additionally, the study says there is often not enough information available to track how much energy is actually being saved.

These are important issues that need to be studied on the local level. But I’d like to see them investigated in a more thorough and scientific manner.

The study also proposes three solutions to the problem: rigorous audits of green projects, local control and flexibility as state mandated “cookie-cutter” approaches don’t always work, and accountability in holding agencies and contractors responsible for project results. The study says “if there are no costs for the agency or contractor for failing to achieve energy savings targets, there is unlikely to be strict enforcement or effective auditing. Without those elements, savings are not likely to materialize.”

In general, these suggestions do make sense. Green projects should be audited and if something is wrong with the design, that information needs to circulate back to the architect so they can learn from their mistakes. Flexibility often has beneficial results (though I don’t know I’d go so far as to change state policy on that front). And there should be some level of accountability for projects or team members that don’t meet their goals.

Now, how do you think we should do this? I’ve heard that rough times (ie the past year, anyone?) are the best times to make sweeping changes to the way we work. But I find it hard to imagine legislators moving on requiring audits or some level of accountability in green building at any point in the near future.

Ignoring the study’s flakiness, is the Washington Policy Center right with their three suggestions? In a perfect world, what would you want to see? What is the best way to ensure that green buildings are living up to their planned predictions?

To support green buildings should codes stay the same, be reworked or be reinvented?

Friday, August 7th, 2009

On Thursday, the DJC published an article I wrote on a new report that says codes are getting in the way of cutting edge green buildings. This, in itself, is really nothing new.  Last August, I wrote this article about the city’s Priority Green program. In it, DPD’s Peter Dobrovolny (whose last name is almost as difficult as mine!) said many projects consider innovative ideas but drop them when they realize how much extra time it will take under city code. However, having the problems and possible solutions written down in an actual report - well that is new.

However, the report. Is. Huge. If you dare to read it, click here . It manages to be very

The Rubik's Cube of codes

comprehensive and vague at the same time. It is comprehensive in that it studies code barriers across the country, identifies problems and makes recommendations. But because it is dealing with national issues, some of the solutions are vague in their range. For example, one solution is to “identify and address regulatory impediments to green building and development” while another is to “create incentives matched with desired goals.”

I spoke with one of the study’s primary authors, David Eisenberg of the Development Center for Appropriate Technology, this week. Essentially, he said codes are built incorrectly in that they are hundreds of ad hoc responses to problems. Codes, he said, should instead be built comprehensively to support a specific kind of development or project. Basically, he said the entire system needs to be rebuilt.

Ouch.

In Seattle, it can take months or years for changes (especially large ones) to occurr. Can you imagine what it would take to wipe out all the city departments responsible for allowing development to get built… and then to rework the system from scratch? 

Eisenberg said he realizes that what he’s asking might be impossible. But even if it is impossible, by voicing the idea, he hopes to get people talking about it. Everyone - he said - whether it’s greenies or permitting people or anyone really - wants healthy buildings. And our current code system does not encourage healthy buildings because it pawns risks relating to climate change and environmental degradation off on future generations.

What do you think about all of this, dear readers? Is there any possibility that our overall codes could be reworked and if so, what would you want them to encourage? Here in Seattle (where we are pretty progressive in environmental issues, at least compared with some parts of the country) do we even need to be considering reworking the system or do we need to tweak it? If you could totally rework one code or issue, what would it be?

Is it better to take a jet to work than a train?

Tuesday, June 9th, 2009

When reporting on environmental topics, I do my best to avoid thinking I know the solutions to any eco problem. Here’s why: environmental topics are tricky. Just when you think you know something is bad for you, it turns out to be good. Just when you think you’ve found the solution to a problem, it turns out your solution has a whole host of other problems.

Here again, is another example of that trickiness: a study by researchers at the University of California, Berkeley, did a full life-cycle analysis of emissions generated by different modes of transportation. And guess what? The study found that in some cases, riding the train could be just as bad or worse for the climate than riding a plane.

Could this really be more efficient than a train?

Now even though I avoid thinking I know the answer, my internal monologue immediately did a double-take. Or, more clearly, said, “NO WAY!”

This article, from NewScientist via the Environmental News Network, does a nice job of summarizing the information.

The researchers looked at 11 different modes of transportation - like the car, train, bus or plane - and then looked at emissions considering aspects like building and maintaining the vehicles and infrastructure, in measuring their effects on the climate.

According to the actual study, “Most current decision-making relies on analysis at the tailpipe, ignoring vehicle production, infrastructure, provision and fuel production required for support… We find that total life-cycle energy inputs and greenhouse gas emissions contribute an additional 64 percent for on road, 155 percent for rail and 31 percent for air systems over vehicle tailpipe operation.”

YIKES!

NewScientist explains the train vs. plane item: passengers on the Boston light rail, an electric commuter train, were found to emit as much or marginally more than those on a mid-size and large aircraft. This is partially because 82 perent of electricity in Massachusetts is generated by burning fossil fuels.

Occupancy also turned out to be a deciding factor. The researchers found that traveling 1 kilometer on a nearly empty bus during off-peak hours emits eight times more per month than taking the same bus at rush hour. Busses with only five passengers were less efficient than cars, including SUV’s and pick-up trucks.

Interesting, huh?

Greed or good natured? Making money off of eco-friendly stuff

Thursday, March 26th, 2009

Being a reporter, I get hundreds of e-mails a week. A good chunk of them are about eco-friendly products that are new, nifty and will “save the worrrllllldddd!” A couple of them are kind of nifty. But the majority of them aren’t… and are obviously motivated by business interests and the desire to make more green.

So when I received an e-mail this week about two entrepreneurs who founded an

Is greed good?

educational campaign promoting tap water, and then just happened to sell over 400,000 BPA-free, reusable water bottles from their Web site, it piqued my interest, precisely because it was addressing the money issue.

These two people - Eric Yaverbaum and Mark DiMassimo - are asking the public in a poll whether they are “greedy entrepreneurs,” “selfless environmentalists,” or both.

Now, both of these guys work in advertising or marketing, so this survey could very well be - and likely is - a marketing ploy. But even so, it’s interesting because it touches on the nebulous and often contentious connection between money and the environment.

The environmental movement isn’t completely comfortable with the notion that people make money off of things that are eco-friendly, especially because not everything that says it’s green really is (this is called ”greenwashing”). But really, the only way to get practices accepted on a large scale will be if someone, somewhere turns a profit in some way.

These two guys are making money but in the process they’re also getting their message - that buying bottled water is bad - out there to a broader audience. So is greed ok if it has a point?

What do you think - are they greedy or selfless? To answer the poll or to see results, click here.

Study measures energy efficiency against economic feasibility

Tuesday, February 24th, 2009

Earlier today, NAIOP national released a report that looks at the levels of energy efficiency a standard office building can achieve while remaining economically feasible.

The study looked at whether commercial development could achieve reduction

The Casey in Portland is designed to use 52 percent less energy than a similar, conventional building

targets of between 30 and 50 percent above ASHRAE 90.1-2004. It compared results on a four-story, 95,000-square-foot, Class A office building in climate zones represented in Chicago, Baltimore and Newport Beach, Calif.

The results?

“Findings show that although significant energy efficiencies can be achieved (varying by climate zone), reaching a 30 percent reduction above the ASHRAE standard is not feasible using common design approaches and would exceed a 10-year payback. The study concluded that achieving a 50 percent reduction above the standard is not currently reachable.”

Here is the breakdown:

Chicago had a 23 percent increase in energy savings at a $188,523 cost increase at an 8.8 year payback.

Baltimore had a 21.5 percent increase in energy efficiency at a $165,148 cost increase at an 11 year payback.

Newport Beach had a 15.8 percent increase in energy savings at a $169,898 additional cost at a 12.2 year payback.

Ouch. Those are long paybacks for most developers. But then again, developers ARE targeting these goals and reaching them. Heck, there are net-zero buildings under development! NAIOP’s goal in developing this study was to prove that a one-size fits all approach does not work in green buildings, but that almost seems to holds true in countering the study, too. Though most of the developers who really push the green envelope, both in design and energy efficiency, are long-term holders of buildings.

Is that what it all comes down to? What a developer’s business model is?

The study also said elements of a holistic, integrated design approach that could create higher energy efficiencies were impractical in the study’s building prototype. The example the study gives is that a geothermal system requires an additional two acres of space, at least in the Newport Beach model.

Oh give me a home, where Seattlelites roam … the New York Times, an age division and density

Tuesday, February 17th, 2009

Yesterday, the New York Times published an opinion piece by David Brooks called “I Dream of Denver.” The piece, based on the late January news on what cities Americans want to live in, calls into question what Americans want from their cities, from density and from their lifestyle.

Reading the piece, I kept thinking about how the descriptions of how people want to

live are quintessentially Seattle culture. One thing Americans want, the article says, is a stuffed garage “filled with skis, kayaks, soccer equipment, hiking boots and boating equipment. These are places you can imagine yourself leading an active outdoor life.” If that’s not Seattle, I don’t know what is. Then again, Seattle was named third on the list of cities Americans would most want to live in.

This sentiment, of people from other cities knowing Seattle and identifying with it, never struck me harder than at the U.S. Green Building Council’s 2008 Greenbuild conference in Boston when faced with a trio of reporters from the Eastern half of North America. When I said I was from Seattle, all three of them (two from New York City and one from Toronto, I believe) all sighed and said, “I want to live in Seattle!”

One of the New Yorkers went so far as to say, “Everyone wants to live in Seattle.”  Which stuck me as funny because from my experience, everyone wants to live in New York. And when going to college in Boston, nobody I spoke with had really ever heard of Seattle.

The reporter went on to say that once people realize they can have an urban lifestyle … and not live in an apartment, they fall in love.

(Not sure if they also fell in love with this city’s must-have-a-car mentality or the lack of a subway but that’s a different story.)

A remote log cabin

The mix of home-life and city-life has always been my favorite thing about Seattle. But the NYT opinion piece points out that urban-living is still an ideal of the young, and I am in that demographic. Even here in Seattle, there seems to be a large amount of baby boomer residents who just want more space, whether it be in another state, on one of the islands or in a more spacious city neighborhood. My mother, for example, recalls the excitement of living in urban Chicago in her youth but now wants nothing more than a remote log cabin in Montana.

Is the desire to live in an urban environment a sentiment of youth? Will we, like our parents prefer to retire in a more remote space? … or is it generational? Will today’s younger generations (meaning Xers, Yers….etc.) still idealize open space and isolation or will we choose density?

P.S. If you read the NYT article, also check out the comments. They’re pretty interesting.

Do green buildings sell better than their counterparts?

Wednesday, November 26th, 2008

At one of the Greenbuild session I attended last week, Andy Florance, CEO of CoStar, said the biggest lie in the construction world used to be “my building is under construction.” Now, he said, “that lie has been replaced by my building is LEED certified.”

That got me thinking about what the highest standard of green building is. Is is LEED platinum? Is it a living building? What about a building that is netzero energy? So I’ve posed the question to you in a new poll at right, and would love to hear what goal you think all buildings should be striving for, if they should be striving for any green goal at all. Or comment below and tell me what standard you think is the best.

But I digress, back to the topic line: do green buildings sell better than their counterparts? According to CoStar, that answer is yes. 

CoStar did a study of the buildings in its entire U.S. database between the first quarter of 2006 and the first quarter of 2008, and based on that information, LEED buildings were 4 percent more occupied than their competitors, renting at $11.33 more per square foot and selling at $171 more per square foot, a 64 percent advantage. Both the occupancy rates and rental amounts climbed - from 4 to 6 percent and from an $11.33 to $18.58 advantage - if you count the past two quarters of this year.

But, Florance cautioned, that information is going to be really tough, if impossible, to measure in the future, thanks to the current state of the economy.

If you want more factual information, read my article in the DJC here that has loads more information on the topic. Or you can see a version of this study dated March here.

Looking for energy incentives and rebates? This may be your answer

Wednesday, August 20th, 2008

This is a monthly post by different representatives of the Northwest Building Efficiency Center. This post was written by Margaret Thomas. 

As a librarian for several years at a library specializing in the area of nbec-logo-sq-3colorsmall.jpgenergy, I responded to questions about energy-efficiency from homeowners, and those responsible for building, renovating or maintaining commercial buildings.

Often, what they wanted to know is: are there any rebates or other financial incentives to help me pay for energy-efficiency improvements? Of course there are, but they are as scattered and unpredictable as mercury on a marble floor.

A variety of utility, local, state and federal organizations offer help. But their programs are buffeted by budget cycles and political whims—they come and go with the seasons. Who keeps up? The Database for State Incentives for Renewables and Efficiency.

The Web site comes with a dangerous URL: dsireusa.org. Get it wrong and you may be in for a shock. Get it right and you are connected to the single most useful and up-to-date source I know of for information about financial incentives.

DSIRE has been around for more than a decade and established itself as a central clearinghouse for information about financial incentives from every source. Funded by the U.S. Department of Energy, the database is managed by the North Carolina Solar Center and the Interstate Renewable Energy Council. They contact program managers regularly and update the database daily.

Posted on the front page is a clickable map of the United States. Choose any state and you get a menu including applicable grants, rebates, tax exemptions, and loan programs. The site also keeps track of relevant rules, regulations and policies.

If you don’t have time to clip coupons or shop around for energy incentives, bookmark DSIREUSA. It’s sites like this that can make a librarian feel as useless as the Maytag Repairman.

Study says green = a better value, quicker sale. Do you agree?

Wednesday, July 2nd, 2008

Yesterday I wrote a story about how GreenWorks Realty  of Seattle crunched some numbers, did a little addition… and discovered that even in the not the best (to say the least) housing market over the last year, green homes in King County have sold quicker and for a higher value than their non-green counterparts.

GreenWorks looked at homes sold on the Northwest Multiple Listing Service small-gb.jpgbetween September 2007 and May 2008 that were “environmentally certified” - here that means LEED homes, Energy Star, or the Master Builders of King and Snohomish Counties’ Built Green Program.

On average, single family homes sold for four percent more, 18 percent quicker, and were 37 percent more valuable per square foot.

To see more or learn how condos measured up, visit GreenWorks to look at the numbers yourself here. (By the way, this is some of the first analysis of its kind).

Now, recently a pretty high level developer in the Seattle area told me there was no point in developing office space that wasn’t LEED certified anymore, because it is going to lose its value quicker.

Combine that with this research saying green homes sell quicker and for more, and logically, building green seems to make sense.

But there are a lot of challenges to building green, not to mention building green well. I could go off about the issues forever: some green systems are so new they are untested or people don’t know how to install them, it’s difficult to know if something is really green, green is “more expensive….” But I would rather hear from you.

If you can take a moment out of your holiday weekend, answer me this: What stops you from building green? If you work on residential projects, could these numbers convince you to try something new? Do these numbers matter at all and why? Do they matter in your neck of the woods, or is the information too Seattle-area specific?

And is it better for someone to do bad green design or do nothing green at all?

Or heck, you can just answer the poll at right!

I’m all ears. To read the story, press here.
