For those interested in sustainability with a specific focus on green building, getting LEED certified is the way to go. The best place to start is with the LEED GA (Green Associate) exam. This exam is a two-hour, computer-based test covering the essentials of green design, construction, and operations. Individuals in a variety of occupations–from real estate to planning to education and beyond–take the exam every year to grow their knowledge and boost their careers. If you're thinking about going for your LEED GA, we at the USGBC MA Chapter are here to help. Our next LEED GA study group kicks off at 281 Summer Street, 5th Floor, Boston, MA 02210, on Thursday, April 4th from 5:45 PM – 7:30 PM. We will meet for the following five Thursdays at the same time and place. The best part is that each session with be led by a seasoned green building professional such as Erik Ruoff or Tom Hardey. Here's the agenda for each meeting:
- 4/4: USGBC Programs: General LEED GA knowledge, GBCI, Rating Systems
- 4/11: Sustainable Sites and Water Efficiency
- 4/18: Energy and Atmosphere and Indoor Environmental Quality
- 4/25: Materials and Resources, Innovation in Design, Regional Priority, & upcoming LEED v4

Time flies when you're building green! The USGBC Massachusetts Chapter launched its Innovation in Green Design Award program back in 2008 with the aim of publicly celebrating the most innovative green buildings and products in the Commonwealth. Hard to believe, but the Sixth Annual awards program is already upon us. That means it's once again time to recognize those projects that have been innovative, yet have also blazed a trail others may follow. Another key aspect of the awards is to promote the triple bottom line, so we'll be looking for projects that make a positive impact environmentally, economically, and socially.
In addition to continuing to give out awards for Innovative Building or System and Innovative Product or Technology, we're very proud to present a NEW category: Massachusetts Green Building of the Year Award! If you have a great green project you want to tell the world about, please enter by this Friday, March 29 at 5 p.m for your chance to win. All Innovation in Green Design submissions should be dropped off or mailed to the USGBC MA Offices (Attn: Grey Lee at Space with a Soul – 281 Summer Street, 5th Floor, Boston MA 02210). Whether you enter the contest or not, join us to celebrate all of the state's green builders at our fabulous Earth Day event on Wednesday, April 10 from 5:30-8:30 p.m at 2 International Place, Boston, MA 02110. We'll have the awards ceremony as well as live music, delicious food and drink, and the opportunity to connect with your green building colleagues. See below for more photos of last year's ceremony.

Managing a landscape, with or without pesticides, is a difficult decision. What’s so difficult you may ask? Pesticides are created to kill things. They are an inherently dangerous product. This should be an easy decision, but the pests they seek to eliminate also bring a danger. There's a reason one of the Four Riders of the Apocalypse was pestilence. After immersing myself in the study of this subject and trying to separate the science from the emotion, I find that the subject is, as in most things, far more nuanced than I initially believed.
I initially approached the subject from the aforementioned position that pesticides, herbicides, and fungicides are designed to kill things, therefore they must be bad for the environment and bad for human health. I also assumed that organic products that are ‘natural’ would be better. When you are asked to counsel a client on their landscape management plan, you will probably find that it's not quite so simple.
Which are safer?
For instance, let’s look at the assumption that organic products are safer than synthetic products. This is not necessarily true. There are organic alternatives that are, in fact, carcinogenic. There are organics that have a higher toxicity profile than synthetic pesticides. One of the most used synthetic pesticides, Chlorpyrifos, is 2.5 to 20 times less toxic than Copper Sulfate, a commonly used organic alternative. Copper Sulfate is carcinogenic and mutagenic. The synthetic pesticide is neither of these groups. Copper Sulfate are also bioaccumulates, which means that its toxicity increases over time. Chlorpyrifos is eliminated rapidly from the body, usually within 24 hours. Just like their synthetic brethren, organic pesticides have warning labels and cautions. One synthetic, made by DuPont, is the first synthetic pesticide that carries no signal word – not danger, not warning, not caution. In fact, it was found to have no adverse effect up to 10,000 times the recommended effective dose – the highest level tested.
Which are better for the environment?
What about the environment? Surely organic products are better for the environment than man made chemicals, right? This too is a dangerous assumption. One recent study in Canada looked at controlling a problematic agricultural pest using an organic regime vs. a synthetic regime. The results showed that the organic regime was more ecologically damaging than the synthetic regime. The reason that organic products can be more ecologically damaging is that they are often not specific. They have a higher mortality on non-target species and the potential ecological damage also extends to organic fertilizers as well. The reason is that the organic products are often not as efficient because they have to be applied at a higher rate to obtain the desired result. The excess becomes run off that contains other undesired components included. Case in point, organic compost often needed for nitrogen is usually undesirably high in phosphorous, which can lead to water pollution issues.
So what are we to do?
We may be asked to develop a plan for our clients, so how do we advise them? First and foremost, you will have to consider the client’s needs. You will have to consider the constraints that they are working under. Is there a regulatory scheme that will guide the decisions? Secondly, you will need to educate them. There are three principles at work: the first is the concept that, “chemicals are chemicals”. It does not matter whether they are synthesized by man or occur naturally. Most aspirin that you take is synthetic and for a healthier alternative you can also chew on 5 pounds of willow bark. In the end, you’re still getting salicylic acid, and the only difference is the means of delivery. The second concept is, “the dose makes the poison”. This is a cornerstone principle of toxicology. If it’s designed to eliminate plants or pests, then it is a poison regardless of its origin. The main question is minimizing the dose and this involves choosing the right tool for the job that is applied in the most educated and judicious manner possible. Keep in mind that the right action may be no action at all. The third concept is something called the precautionary principle. The precautionary principle simple states that, “when an activity poses a threat to human health or the environment, precautionary measures should be taken even when the cause and effect relationship is not fully established scientifically.” This idea is often misinterpreted to mean that “it is better to be safe than sorry”. What is needed is a balancing of the risks. What are the risks of using the tool versus the dangers of not using it? Avoiding the potential “sorry” part of the precautionary principle does not guarantee, in reality, the “safe” part.
Take the balanced approach
Integrated Pest Management is part of LEED. It strikes the balance and its approach is that one should use the least damaging, ecologically or physiologically means possible to achieve your desired end. It is a careful progression that balances the twin harms of action and inaction, requiring care and forethought in the actions one contemplates. This leaves open the ability to use the most effective and efficient tool, provided all other options have been tried. Clients may wish to use an all-organic approach that may be part of their value set. They must understand the trade offs in quality, costs, efficacy, toxicity, and environmental benefits. Other clients may value the perception of quality or want to minimize labor costs, maximize safety, seek to avoid the broken window effect, or view nice grounds as a means of attracting or retaining employees and customers. All clients wish to avoid liability, the risk of disease, issues with a board of health, or infestation. Most people want to preserve the investment they have in their property while having the smallest ecological footprint and the healthiest possible site. That can be done by balancing all options and understanding the entire equation.

LEED for Homes Certification has two paths: Low-rise and Mid-rise. In addition to having some different 'optional point' credits, the two certification paths have some key differences in Prerequisites (the pass/fail items). One of these differences, which I will discuss in this post, is EQp12.1 – Compartmentalization of Units.
Compartmentalization is an air sealing practice that focuses on limiting air movement between dwelling units within a building. Historically, the exterior boundary has been the primary plane for reduction in building air leakage. More recently, air leakage across unit boundaries has been targeted for more than energy savings. Where air can travel, sounds, smells, heat, cold and rodents can as well. The goal of the compartmentalization requirement in LEED for Homes Mid-rise is to reduce the movement of all these things. Many of us have probably experienced an apartment where neighbors share more than just the common stairwell.
|
Figure 1 |
Figure 1 demonstrates the intent of compartmentalization. Solid lines in this image represent walls that have been sealed to act as continuous air barriers and dotted lines indicate walls that have not been sealed. The floor plan to the left represents a building in which only the exterior boundary has been sealed while the floor plan to the right represents a building that has been compartmentalized, or sealed to prevent air movement between units.
Now, you may be thinking, how hard can it be? The entire unit gets gypsum on the walls and with the ceiling, windows and doors being sealed, where can the air come from? Well, let me tell you something: air can be sneaky!
It finds its way anywhere that it can – whether through a light fixture, electrical outlet, duct chase or behind baseboard. If you don't seal it, it will come, and meeting the LEED for Homes Mid-rise prerequisite doesn't happen by accident.
|
Figure 2 |
Figure 2 is a cross-section of a multifamily building in which we are looking at one unit which is bounded on all sides by other units. The orange dotted line represents the interior gypsum on the walls, ceiling, and the floor. The red arrows indicate the paths for air leakage, which can be found coming through electrical penetrations such as wall outlets and ceiling fixtures. It can also enter the unit through penetrations made by ductwork and unsealed framing in spaces between unit ceilings and subfloors above.
In my experience, residential units that have not had a compartmentalization goal are typically measured at twice or more the allowable leakage level for LEED for Homes Mid-rise. Working with a LEED Green Rater from framing, insulation, finish, and focusing on compartmentalization has shown to be an effective way to help projects meet their air leakage requirements.

Boston's Mayor Thomas Menino has announced an Energy Disclosure Ordinance.
The establishment of this requirement will “provide information to owners, residents, and prospective buyers and tenants, and, through education and the operations of the market, create incentives to participate in energy efficiency programs.”
Energy efficiency in existing buildings is the single most important component of the City's plan to reduce greenhouse gas emissions 25 percent by 2020.
New York, Philadelphia, Seattle, San Francisco, Minneapolis and other cities have enacted energy reporting and
disclosure requirements in their jurisdictions.
Leading by example, Boston would annually disclose its energy and water use in all of its facilities starting with the 2012 building data. In the following years, the ordinance would apply to non-residential buildings greater than 25,000 square feet and residential buildings 25 units or more. The proposed roll out schedule for reporting requirements is as follows:
- Non-residential buildings 50,000 square feet or more in 2014
- Residential buildings with 50 units or more in 2015
- Non-residential buildings 25,000 square feet or more in 2016
- Residential buildings with 25 units or more in 2017
In addition to reporting energy and water use, buildings may be required to conduct energy audits or other evaluations every five years to identify opportunities for energy efficiency investments. Buildings in the top tier of energy performance or already taking significant efficiency actions will be exempted from this requirement.
Reducing greenhouse gas emissions through investments in energy efficiency is the largest component of the Mayor’s Climate Action Plan. Mayor Menino has established Boston as a national leader in reducing greenhouse gas emissions and promoting a clean energy economy through initiatives such as Renew Boston and the first in the nation's green building standards for private developments. To further inspire action, Mayor Menino has launched Greenovate Boston, a new sustainability movement to ensure a greener, healthier and more prosperous future for the City.

This is a guide for LEED® accredited professionals and eco-conscious individuals on how to apply the LEED® credit scorecard to their personal lives.
Why should only buildings benefit from the LEED® requirements? If we follow the LEED® guidelines so that our projects can hit silver, gold or even platinum, then why not apply those guidelines to our everyday lives? By applying the scorecard to our daily life, we demonstrate that LEED® is not just limited to buildings, but it is for everyone. It shows that we not only talk the talk but walk the walk.
My posts will be part personal journey, part advice column, and part standard by which we all live by. Living LEED® is for everyone, not just about me writing my personal reflections or giving advice. It is about you and your journey to your own personal silver, gold, platinum or even higher achievements! With this column, I declare a new standard that should be named as the EVERGREEN standard. Let’s be like the Evergreen Trees, who in their long fruitful lives, give us more than they take. So let us give back to the environment more than what we take from it.
For reference: the posts will follow LEED® for EB and NC, but to get to EVERGREEN level we will incorporate the other LEED® disciplines as Homes and CI whose credits cross pollinate. The choice of including LEED® for Homes is practical because it is where we spend much of our lives, in and around the home.
I call out to all my LEED® professionals and eco-conscious colleagues to contribute to credits that you have personally achieved and I will incorporate them here. I will try to write in each edition credits in the order they appear. This new Evergreen level doesn’t come with a prescribed checklistt uses the LEED® checklist as a reference to achieve a level greater than before.
Our first attempt at EVERGREEN standard is to achieve credits in the Sustainable Sites section .
In the current version of EB and CI you get a point for having a LEED® certified building. If you are living in a LEED® Certified building or Home, you are ahead of the curve. My townhome is not LEED® certified.
The best that I can do is go for Energy Star. Everyone needs to go here and learn as much as they can. If you can, register your existing or new home to get it up to Energy Star standards.
Not ready for Energy Star? Then consider Mass Save®. Here you can begin the journey to energy savings and dollar savings! Mass Save is chock full of rebate programs that will send you in an Evergreen direction!
There are many more components to Sustainable Sites. In the next few posts, I will try to incorporate the credits that directly affect us as people or credits that can be used in conjunction with people. Without infringing on USGBC or Energy Star copyrights, we will reflect on the credits and checklists that inspire an Evergreen Level of standard we can all live by.

UTEC also holds the distinction of being one of the oldest LEED certified buildings in the country. UTEC renovated the former St. Paul’s United Methodist Church building that was built in 1839 and was certified as LEED Platinum last November. The expansion of the building will allow UTEC to double the number of youths in their Workforce Development and Education programs.
There are 147 solar panels on the roof of the historic building and the project team also incorporated soy-based insulation in the basement. Other sustainability features include an electric car-charging station, solar chimney, passive cooling system, and natural daylighting.
The building will also have a youth-run café open to the public, serving locally-sourced food. It will also have a Green Resource Center with interactive displays.

It's always difficult getting folks to break out of their routine and embrace a better way of doing things. This is even more true when you propose a more environmentally sound way of doing things. The innovation may be a bit easier to adopt if it came with benefits such as lower costs, less maintenance, a better user experience, and demonstrable environmental benefits.
The opportunity is sweetened further if it comes with some free money.
This is exactly the case with switching from gas powered outdoor maintenance equipment to propane power and it can be done with significant grants to offset the initial costs. These grants are available from the Propane Education and Research Council. They provide for up to $500 to convert a gas powered commercial mower to propane and up to a $1,000 rebate for the purchase of new propane powered mower. More info can be found here.
Why would somebody want to do this? After all, you are just swapping one fossil fuel for another. This seems true, but anyone pursuing LEED-EBOM will be putting together a forward looking landscape maintenance plan and it is also important for the SITES certification. LEED v4 specifically offers credits for site management plans that adopt gasoline free and low emission landscaping. The idea also makes sense from both a fiscal and a sustainability perspective.
Reducing costs
All groundskeepers, whether on a commercial campus or a public park/school, are concerned about ever-shrinking budgets. Converting to propane based equipment can help; the cost per gallon equivalent is between 30% and 50% less because, unlike gasoline, it is easier to negotiate a contract price for a full year. Secondly, the maintenance interval for propane equipment is much longer; many people see oil changes move from every 25 hours to every 100 hours. Third, The equipment lifespan is frequently increased. Commercial mowers typically need to be rebuilt or replaced at about 2,500 hours. Propane powered equipment can see a 50% improvement due to cleaner oil and pistons. Finally, the loss of fuel due to theft and spillage is virtually eliminated.
Reducing environmental impact
Spillage of gasoline is an often overlooked environmental problem. The EPA estimates that 17 million gallons of gasoline are spilled annually when fueling landscaping equipment. The lack of spilled fuel is just one of many environmental benefits. According to the EPA, about 5% of ALL air pollution is generated by lawn care equipment. Propane powered equipment can help with this problem. Propane yields more than a 25% reduction in green house gasses versus gasoline. It reduces carbon monoxide emissions by greater than 60%, generating fewer ground level ozone precursors and fine particulates than conventional gasoline powered equipment. Conversion kits are certified by both the EPA and the very strict California Air Resources Board (CARB). Most jurisdictions even allow for the use of propane powered equipment during ozone action days when ground level ozone concentrations force the shut down of gasoline powered small engines.
Similar performance to gasoline
A question often asked is, “The benefits are obvious, but how does it perform?”. The market itself is beginning to answer that question. Many major landscaping outfits, particularly in the south and west where they are often subject to ozone action shutdowns, are switching to propane. They claim that they have the same power with all the benefits. Operators like it because it can be quieter and they are exposed to less fumes. One issue that I have uncovered is that propane is somewhat less energy dense than gasoline. This results in the range of a tank of propane being equal to about 3/4 of that of a comparable gasoline tank. The issue of fuel transfer can also be an issue. Large operators will benefit from an on-site tank filling infrastructure, but this is a large upfront expense. These costs can often be offset by grants and rebates, which are worth pursuing. Smaller operations can have a dedicated tank exchange installed, similar to those seen at supermarkets or hardware stores.
One advantage to investing in a propane filling station is that it allows for the future expansion into vehicles. I have driven propane and natural gas vehicles and have found them to be identical in performance to gasoline. Having a fueling station would allow for large vehicles to be converted to propane. The lack of a wide array of fueling stations limits a vehicles use, but operating out of a central location that is equipped with a fueling station makes sense.
A reasonable alternative
Electric powered equipment would be the best choice. They could be powered via alternative means and would emit next to nothing in hazardous air pollutants. There are several viable electric options available for smaller pieces of equipment (blowers, trimmers, saws etc.), but electric still does not have the range or power needed for larger pieces of machinery. However, propane can power smaller engines such as blowers, both large and smaller ones. One of the best solutions I have seen is a solar array that powers a battery recharging station with interchangeable batteries for the smaller pieces of equipment and propane for the higher power equipment. This could be a bridge solution that is enhanced by the prospect of free money.

What a great Annual Meeting on Monday night! Thanks again to Rachel Zsembery, Dee Spiro, Katya Carman and Carlos Alonso-Niemeyer for putting together such a fabulous evening! Thanks to everyone who came early and stayed late to help make it all happen. Thank you to Andrea Love and Payette Associates for providing their Practice Room as a great hall to gather in.
[above: Kathy Arthur-Tyler of our Green Schools Committee (also of NStar, one of our sponsors!]
Thanks indeed to this wonderful community we have where even with snow and sleet and rain, (all at the same time) (and rush-hour!) we had a full capacity crowd.
Thank you to Brian Swett [below] for making such an awesome presentation about the
ambitious goals of the City of Boston and for reaching out to us to help partner with them as they grow their efforts – we can help bring proven models of success to other communities here in Massachusetts
And now the work continues. I know some of the committee volunteers made connections to new helpers. For me, the top priorities are Community, Capacity and Advocacy – which means getting more members, bringing in new sponsoring partners and focusing on specific policy projects. The advocacy is really the most important thing we can do as an organization. What are we doing? I believe we can choose one or two of the
USGBC campaign issues. In my conversations that some of you have heard, I think that those can be Greening the MLS and Energy Reporting going statewide. With our Green Schools strategic investment grant, that will be a focus in the coming months. And finally, pertinent to current events, we need to respond to the wild community development opportunities and building projects that are the future
Casinos of Massachusetts.
[me with active volunteers: Andrea Love, Emily Greenstein, Dee Spiro, Phoebe Beierle, and Jim Newman]
I was really psyched to hear about the awesome work going on in the committees – Green Residential, Green Schools, RASOC, Education, Communications, Membership, Special Events and Emerging Professionals. I look forward to our future advocacy team. I am heartened by the West Branch and the Central Mass group with their successful and upcoming events. We’ve got a lot of great stuff going on!
Take a look at the website – there are new stories up there and I have been updating it (with our Communications Associate Zak) every week. Please stay tuned to our social media spaces
facebook and our
LinkedIn group – plenty of news and discussion there.
[Hi Phoebe!]
We are moving right along – new people in the ranks, old-timers coming back into the fold, and a lot of work to tackle. As we mentioned last night:
Massachusetts is #4 in the country in terms of LEED certified space created (per capita) in 2012. Not that LEED is everything to us (it’s just our biggest horse in the market-transformation team), but 101 projects earned the status last year, taking us to just shy of 400 certified projects total up til the end of 2012. This really means a lot of us and our peers who aren’t quite yet members are working on a lot of green building projects. We really are changing the carbon intensity of our communities, which is one giant step to making the world a better place. I’m proud to work for all of you and I look forward to cultivating this momentum for even more victories in the coming months and years!
Thanks again for being part of the USGBC MA Chapter! See you at the next event!
