Deep Energy Retrofits with Brian Butler and the Residential Green Building Committee

By Rose Brakesman

By Rose Brakesman
 
What better time to talk about Mass Save Deep Energy Retrofit than on a cold February evening with the Residential Green Building Committee. Brian Butler walked us through how Boston Green Building does a Deep Energy Retrofit (DER).
Some DER “rules of thumb”:
1.5 air changes per hour (ACH)
R5 windows
R10 basement slab
R20 foundation walls
R40 walls above foundation
R60 in the roof/attic
DER is documented and looks for a reduction in energy use between 50-90%, so the process starts with determining a baseline on energy use and a blower door test to document the number of air changes per hour (ACH) in an existing older house. Many of these houses are what Brian calls “gushers”, which are houses that leak air and energy at an alarming rate. One house that Boston Green Building is tackling for DER just went through a blower test and had 9 ACH. (DER is 1.5 ACH).  9 ACH is equivalent to leaving a two foot by two foot hole in the exterior wall year round! 
Jokes abounded… “Did you leave the bathroom window open during the test?” Nope, double checked. Many older houses are just that leaky from gaps around the windows and doors, leaks where the basement meets the frame, and so on. This is the kind of house that can most benefit from a Deep Energy Retrofit and there are many like this. 
Additionally, most of the current housing stock in Boston will still be here in 2050, so building better new homes won’t help nearly enough. Happily enough for Brian and his cohorts, it doesn’t look like they’ll run out of work anytime soon! Even nicer is the DER “guidebook”- the Mass Save Deep Energy Retrofit Builder Guide; this is more helpful than a long process of repeated submittal, revision, and re-submittal so that the guidebook streamlines the process. Hopefully more builders will jump on board and provide some DER competition!
 
After addressing the building envelope, there are typically additional complications and hazards that go along with “tightening things up.” One such issue is indoor air quality. In the original leaky building there’s a “stack effect” where supposedly “fresh” air starts in the basement (along with mold and mildew), then it moves upward through the house via temperature stratification. Once the building envelope is at 1.5 ACH or less, then there is no stack effect. Facilitated ventilation is required and that is a very good thing. Now stale air can be taken from one area of the house that will be moved through heat recovery ventilation (HRV). A high efficiency HRV unit is the best way to go and can have an efficiency of 90%, which means stale air at 72o is exhausted and fresh air is drawn in at around 65o.

In the end, Brian and Boston Green Building are “dragging poorly performing homes kicking and screaming into the 21st century and hopefully addressing all the issues to keep from killing the occupants.” Originally, only one utility company participated in Mass Save DER, but now there are six participating utilities. Conspicuously absent from the list is NStar….but there is some carbonated bottle shaking going on to hopefully bring them back on board.
 

See you at the next Residential Green Building Committee meeting on Monday, March 10th at 5:45pm at 281 Summer St, Boston!

LEED Exams Change-over to LEED v4:

By Grey Lee

This just in from USGBC National:
 
The LEED Green Associate and LEED AP exams will evolve for the LEED v4 rating system in June. The last day to take the credential exams with LEED v2009 content will be June 15, 2014. The first day to take the exams with the new LEED v4 content will be June 30, 2014. No tests will be administered in between these dates.
 
For the first time, LEED project experience competency will be assessed within the LEED AP exam. Practitioner experience is critical to the LEED AP designation; as such, proficiency will be tested objectively within the LEED AP exam itself. The requirement to submit proof of LEED project experience at the time of application is no longer required as of June 30. However, GBCI strongly urges candidates to gain meaningful project experience prior to taking the test, as it is critical to successful exam performance.

Innovations in Sustainabiltiy & Resiliency

By Grey Lee

We had a great program in our EcoDistricts series. Thank you to event sponsors EnerNOC, the City of Boston, the Boston Redevelopment Authority, and to District Hall for hosting us!

From the Boston Redevelopment Authority:

On Tuesday, 2/4/14, the BRA and the Massachusetts Chapter of the U.S. Green Building Council (USGBC) hosted an Innovations in Sustainability and Resiliency panel discussion. Panelists representing the finance and tech industries, as well as government, came together to discuss the development of EcoDistricts and the role of resiliency in Boston's Innovation District and beyond. The EcoDistricts framework emphasizes sharing energy solutions amongst area stakeholders. Over 100 attendees participated from a broad cross section of the sustainability community that included architects, engineers, developers, financial consultants, and federal/state/local government officials.
 

 

The first keynote speaker was Kairos Shen, Chief Planner at the BRA, who emphasized that the biggest challenge facing the creation of Eco Districts is partnerships. Shen stressed that the technological solutions already exist, but it's the partnerships that will allow them to be effective.
 
The second keynote speaker was John Aubrecht, President of the Longwood Medical Energy Collaborative, who represents Boston's greatest concentration of medical institutions that includes over 2,000 hospital beds. The concentration of critical energy users in the Longwood Medical Area (LMA) rely on the Medical Area Total Energy Plant (MATEP) for heating, cooling and electrical services. Aubrecht's presentation focused on building partnerships between LMA institutions, financial institutions, and energy markets. He also discussed the challenge of finding organizational strategies for the multiple stakeholders in an Eco District.
 

The panel on Eco Districts was moderated by Galen Nelson, Director of Market Development at the Mass Clean Energy Center. Nelson discussed his time in Hamburg, Germany where an old grain silo was used to create an energy bunker that now produces enough heat for 3,000 households and electricity for 1,000 homes. Other panelists included Karthik Rao from EnernNOC, who discussed how each individual building can contribute to local energy markets; Vice President of Natural Systems Utilities Bruce Douglas, who discussed the use of waste heat in sewer systems and capturing underutilized sources of energy throughout the city; Director of SustainServ Matthew Gardner,  who discussed emerging technology used to measure the energy of a city and showed how it was applied in the Innovation District; Director of Boston Global Investors Charlie Reed, who discussed his company's planning strategy for district energy in the Innovation District.
 

 
More panels discussing EcoDistricts beyond energy technology are forthcoming, including EcoDistricts in the context of water and organizational models. Stay tuned via the BRA EcoDistricts page.

Living Buildings are On Their Way

By Grey Lee, Executive Director

The Living Building Challenge (LBC) raises the bar on the level of sustainability pursued in green building projects.

 

The Chapter hosted a presentation on the LBC by Shawn Hesse of emersionDESIGN. Shawn is a Living Building Challenge Ambassador and member of the Cambridge Net Zero Taskforce. He is also a loyal member of the USGBC MA Chapter.  Thank you to Shawn for presenting and to Laur Fisher for organizing the event that was held at the MIT Center for Collaborative Intelligence in Kendall Sq. Cambridge!

 
About 25 people came out to hear the in-depth introduction to the challenge. A considerable amount of contingent came from Harvard University.  Could there be something in the works? Maybe, as an organization, we can support a friendly little contest between a few of the campuses around here! There is already a Living Building coming together at Williams College in Berkshire County. Others came from architecture practices, the City of Boston, the State of MA, and other institutions. Thank you to all who could make it, even with the “snow emergency” bells ringing!
 

The Living Building Challenge is a philosophy, advocacy tool and certification program that addresses development at all scales. A one hour introduction by Shawn reviewed the seven performance areas, the certification process, and reviewed project examples. What if every single act of design and construction made the world a better place? It is really an inspirational system.

 
The USGBC MA Chapter looks forward to working with the LBC community to facilitate greater adoption of the principles of the Living Building Challenge into our industry. Let us know if you are interested in learning more and/or advocating for more Living Buildings!

MPG Ratings for Homes? They're coming!

By Michael Sigmon, Communications Coordinator for the Residential Green Building Committee

This entry written by Michael Sigmon, Communications Coordinator for the Residential Green Building Committee
Alissa Whiteman and Ben Pignatelli from the Massachusetts Department of Energy Resources (Mass. DOER) made a presentation to the Residential Green Building Committee on their pilot program on the Home MPG (Home score card). It was a well-attended meeting with over 20 people arriving to connect on the topic. As soon as the first slide was up, the rowdy bunch was firing off questions and making their own analyses of the project. Alissa and Ben were great, very able to handle the “shark tank” of residential energy efficiency sharpshooters in the room. All in all, it was a great discussion and everyone learned something new. Hopefully the group was able to provide some useful feedback as the DOER looks at expanding the program to other areas of the state.
 
 
The pilot took place in the Springfield, Massachusetts area and surrounding towns. The data collection took place in conjunction with the free MASSAVE energy audit that all rate payers of public utilities can ask for. The pilot was funded by the U.S. DOE and is taking place in 9 geographic locations across the US. Read about the pilots across the country here.
 
 
 
The idea behind the pilot was to create a straightforward way for the average consumer to identify the important components of a home based concept on apples-to-apples comparison. Using a prescriptive method, the DOER identified HVAC systems, domestic hot water systems and envelope insulation values for formulating their scoring system. Their thought was that by using this metric, they could make a fair comparison across dwelling unit types. This also leads to consumer education that is crucial for good decision-making in selecting energy efficiency measures for a home.
 
 
After getting their audit and initial score card, the plan is to render a second score after weatherization and equipment upgrades have been completed. A part of the score card is a projection of a home’s carbon rating, which can inform the occupant even further about the impact of their house's energy performance.
 
 
 
Organizations that cooperated with the pilot are the Center for Eco Technology and the Pioneer Valley Planning Council.
 
The program results are for the Springfield area:
2116 Score cards
799 Retrofits
 
 
Thanks again Alissa and Ben!
 
 
 
The Residential Green Building Committee holds a meeting every month, usually on the second Monday, at the USGBC MA offices in Boston. Each meeting has a presentation on a relevant and timely subject from experts in the field.  Various aspects of committee business are then attended to ideas such as our advocacy work, communications, creating resources for the community at large, and other work that supports the Chapter's mission. Feel free to come check us out – our next meeting is Feb. 10th.

West Branch of the USGBC MA – 2014 Recap – Lots of great programs in Western Mass. last year!

By Grey Lee

Letter from Chairs Past and Present  
Dear colleagues,
2014 has come in with blasts of cold and ice, but it would take a lot more than that to temper the passion of local volunteers who are focused on promoting “the design, construction, and operation of sustainable buildings and communities in Massachusetts”!
 
The USGBC MA – West Branch had its best year ever in 2013 and we are all ready to launch another successful year of green building education programs, networking events and service projects!
 
For those of you who couldn't make it to all of the excellent programs we provide, We thought we would prepare a short list of highlights from 2013:
 
We had a variety of Education Programs!  The LEED Green Associate Exam Prep course attracted approximately 45 students and utilized a team-based learning classroom at UMass to facilitate discussion among students and professionals.  We held two Green Eggs networking and education events – the first at David R. Northup Electrical Contractors, Inc. on Point of Use Technology presented by John DeGray of Point Energy Solutions and the second at the EcoBuilding Bargains Store on Energy Modeling presented by Benjamin Todd of Strategic Energy Group, as well as Ted Mendoza of UMass Amherst.
  
Our Summer Social in June attracted almost 30 members and included representatives from NESEA and the Westover Job Corps.

Green building researchers from UMass Amherst presented a map of LEED buildings in Western MA, featuring 27 LEED certified buildings and 60 more projects undergoing registration – a remarkable achievement for our region!
 

UMass Green Building Council Students Group was founded in partnership with the West Branch and is committed to promoting sustainability, innovation, and a basic foundation of Leadership in Energy and Environmental Design, both on and off campus.  They provide campus-wide initiatives and education for the public on green building practices.  Eight student members attended the GreenBuild 2013 conference in the fall.  A team of students worked with NStar to survey residential halls and educating students on saving energy by distributing 5,000 LED light bulbs.
3 Green Apple Day of Service events focused on engaging local schools took place in September and October: a Green Building Tour of 4 UMass LEED facilities and rain gardens for students from Westover Job Corps, a tour of Tan Brook for students at Wildwood Elementary school in Amherst, and a public tour of the Massachusetts Green High Performance Computing Center in Holyoke, a LEED Platinum Building.  We have also committed to provide LEED Support for the Common School in Amherst.

Thank you for your support,
Ludmilla Pavlova, Immediate Past Chair
Mark Dunn, 2014 Chair of USGBC MA West Branch Steering Committee

 
[[ Congratulations to all the volunteers who have helped to make this success possible! We all look forward to a great 2014 and more useful and fun programming to support the green building community in Western Massachusetts. ]]
