Residential Green Building Committee Meeting: 3/14/16

By Celis Brisbin, Programs Manager

 

The Residential Green Building Committee gathered on March 14th 2016 before the “Policy Podium: Panel Discussion on Energy with Legislators and Industry Pros” that followed. We reviewed the goals we set for 2016, such as recruiting more passionate people to Chapter, and established that the personal connection is crucial in doing this.

 

One of the projects we have in the works is an Integrated Energy Efficiency Program. We want to make it easier for developers and contractors to see they have access to energy efficiency incentives available to them, when pulling permits prior to construction. We need to start with one city at a time and make the change to implement these Energy Efficiency programs as mere options, not requirements.

 

Increasing this awareness of programs will benefit both the developers/contractors and homeowners alike. Eventually we want these programs to exist statewide, and be presented in an easily understandable way for those involved at the beginning of the construction process.

 

While this program will drive people to MassSave, it doesn’t stop here. There are a multitude of incentives that exist, and we just need to find the right way to make this information accessible in an easily understandable way. We should especially target Stretch Code communities, as they are most likely going to respond positively since they are already on track to utilize energy efficiency upgrades.

Stay tuned for more updates on our next Committee meeting on April 11th (Sign up HERE), and our next Policy Podium on April 14th (Sign up HERE).

 


 

National Grid: Energizing Nature

By Ritchie Lafaille, Office Fellow

The Natural Grid” program, which sees National Grid using its green spaces for good, has been named a finalist in the BITC Environmental Leadership awards. Environmental Sustainability Manager Ian Glover explains why it’s so important for the business to make a positive contribution.

Some of the UK’s most treasured species, including birds and butterflies, are in significant decline as their habitats shrink and become more fragmented. Through our Natural Grid program, they’re finding new ways to use our land which benefit our neighbors and communities and, in doing so, improve the quality of nature on their properties.

The program was born from their environmental and sustainability strategy, which they rolled out in 2012/13. One of the big themes they looked at was how, as a company with significant amounts of land, they could not only minimize their environmental footprint, but deliver more positive benefits by enhancing the natural world alongside their energy grids.

Along with the clear environmental benefits, it’s important that the program makes sense to National Grid as a business. As a highly-regulated organization, they need to show that everything they do is creating returns and providing value to their customers. To help demonstrate this, they’ve developed valuation tools that actually put a price on these “priceless” assets. They allow National Grid to highlight their value, prove that the programs they put in place are more efficient, help them reduce risk, increase long-term environmental quality and enhance their reputation.

These tools tell us that National Grid has up to £500 million of natural capital value there! So it’s vital that they make the right decisions that not only preserve that value, but enhance it.

The Natural Grid is growing and they’re proud to have been named a finalist at the BiTC’s Responsible Business awards. It’s recognition that they’re showing new ways for land and natural assets to be managed that are more efficient, collaborative and drive environmental improvements.

National Grid is also seeing a lot of personal passion on display across their sites. Many of their people are voluntarily looking out of their windows and taking the opportunity to build bird boxes and new habitats for local wildlife. The Natural Grid is a fantastic opportunity to get even more colleagues and construction partners engaged in breathing new life into our precious landscapes. Thank you to Chapter Sponsoring Partner National Grid for building on their commitment to sustainability through this program!

A recap of our Net Zero Building Tour at the Dept. of Fisheries and Wildlife

By Kevin Provencher, PDA Associates, Inc.


On Tuesday February 23rd, the USGBC MA Chapter hosted an in depth discussion and tour of the LEED Platinum, Commonwealth of Massachusetts Division of Fisheries & Wildlife Headquarters located in Westboro, Massachusetts, winner of the Chapter's 2015 Innovation in Green Design Award. Designed for net zero energy performance with direction from the Division of Capital Asset Management and completed in early 2015, the facility is on-track to meet and perhaps exceed its performance goal in 2016, according to Conor McGuire, Director of Sustainability at Columbia Construction Company. The project was designed to be the first publicly owned net zero energy building in the Commonwealth. Conor was joined by Dan Arons, Principal Architect for Architerra, Inc. who was responsible for design of the project. They report the facility was 94% efficient in first year of operation. Record breaking snow accumulation and cold temperatures in February of 2015 reduced the energy output of the rooftop photovoltaic array to below expected levels; however the overall annual performance suggests the facility may even be net positive in 2016.  

Located on a beautiful cleared and gently sloping hilltop site overlooking a wildlife management area at the edge of the former Lyman School campus, the two story building responds to the horizon with the long side oriented on the east-west axis for maximum solar exposure. The sloping shed roof is covered by an impressive 300 kW photovoltaic panel array. A deep overhang on the south facing façade provides shading for interior spaces from high angle sun in the summer months, reducing solar heat gain during the cooling season, but allows low angle winter sun to penetrate the interior to offset the heat load during the heating season. North facing clerestory windows allow daylight to penetrate the interior, reducing the energy required for artificial illumination through daylight sensors and controls, which regulate interior lighting levels based on the available daylight.  Vacancy sensors were chosen for daylit spaces to avoid turning lights on unnecessarily. Unlike an occupancy sensor, a vacancy sensor requires the room occupant to turn the lighting on manually when entering the space, then turns the lights off automatically after the occupant leaves. When adequate daylight is available, the occupant is less likely to turn the lights on. 

The exterior walls and roof are constructed of structural insulated panels (SIPs), a layer of foam plastic insulation with oriented strand board bonded to both sides. When compared to framed wall and roof assemblies, SIPs allow for continuous insulation uninterrupted by framing members, maximizing the insulating value in a minimum depth. A continuous air and weather barrier was applied over the SIPs behind open joint rain screen panels. Maintaining the continuity of the air barrier is critically important to the thermal performance of the building envelope. Whole building blower door testing confirmed the building's air barrier performed at an average leakage rate of .062 cfm/ft² at 75 Pa, far exceeding the minimum energy code performance value for building tested assemblies (0.40 cfm/ft²). The open joint rain screen design allows for bulk water to penetrate the cladding and drain down the face of the weather barrier in the air cavity behind. Ventilating the cavity promotes air circulation and drying which increases the overall resilience of the wall assembly.

In addition to passive design measures, the project utilizes highly efficient environmental systems to drive down the Energy Use Intensity (EUI) which is a measure of the energy consumed annually per square foot at the site. The design and engineering team targeted a low EUI (26.3KBtu/ft²/yr) which could be offset by the renewable energy production available from the photovoltaic array, resulting in a balance of energy consumed with energy produced on site. The building's primary systems are all electric, which eliminates on-site combustion of fossil fuels and carbon emissions.

The key strategy employed by the team for reducing the EUI includes separating the heating and cooling systems from ventilation air through the use of a dedicated outdoor air system (DOAS) and low temperature hydronic radiant floor and ceiling panels. Compared to air delivery systems, a low temperature differential between heating and cooling modes is possible when radiant energy is utilized to maintain thermal comfort. Further, the pump energy required for hydronic systems is significantly less than the fan power required for air systems to deliver heating and cooling. Hydronic systems become more increasingly more efficient than air systems as the size of the building increases. The low temperature differential is supported by a ground source heat pump system with 20 closed loop wells by transferring the thermal energy of the ground beneath the site, which is at near constant temperature year round, to the building's heating and cooling systems. 'Free cooling' is available during the swing seasons via bypassing the heat pump compression cycle and running the cooling tower.


The energy required to meet the ASHRAE 62.1 ventilation standard required for LEED certification is offset by the dedicated outdoor air system. Latent load, which is the energy required to remove moisture from air without change in temperature, is decoupled from the sensible load, which is the energy required to raise or lower the air temperature, by dehumidifying the ventilation air. The thermal energy of the air returned from the interior spaces is exchanged with the incoming ventilation air by an energy recovery ventilator (ERV). The entire latent load and a portion of the sensible load are taken by the DOAS, while the hydronic radiant system handles the balance of the sensible load. The overall result of running the two systems in parallel is a highly energy efficient solution that provides superior thermal comfort for the occupants.

Thank you to Conor, Dan and the staff at the Division of Fisheries & Wildlife for leading the in-depth discussion and tour of this skillfully designed, engineered and constructed net zero energy facility.

Learn More about COP21 in a Green Building Context!

By Ryan Duffy, Communications Fellow


This March, in just a few weeks, the USGBC MA chapter will be hosting a special COP21 Paris Climate Talks Unconference to revisit these important international conversations.

This is a unique opportunity to discuss the historic 2015 United Nations Congress of the Parties (COP21), held this past December in Paris, France.  The provisions and commitments reached in the agreement have global implications for sustainability, climate change, and green building, and certainly warrant a closer examination, extensive analysis, and more discussion.

For this reason, we have put together a half-day event featuring a community of experts from a variety of organzations and firms. Panelists who attended the Paris climate talks will be present, with break-out groups led by local issue experts.

SIGN UP NOW

Partnering Organizations: 

  • Sierra Club
  • CABA, Climate Action Business Association
  • Foundation for a Green Future
  • ELM, Envoronmental League of Massachusetts

  • Professor John Sterman, MIT System Dynamics Group

Our unConference Discussion Leaders:

  • Josh Craft, Environmental League of Massachusetts
  • Henrietta Davis, former Mayor of the City of Cambridge
  • Elizabeth Saunders, Clean Water Action


More about the Event:

More than 30 per cent of global greenhouse gas emissions are buildings-related, and emissions could double
 by 2050 if we carry on business as 
usual. Inaction increases risks and vulnerability of countries, regions and local communities from climate change. Yet:

  • The buildings sector offers one of the most cost-effective and economically beneficial paths for reducing energy demand and associated emissions while at the same time supporting adaptation and resilience to climate change.
  • Many low-energy, renewable and deep- renovation solutions are available. Proven policy, finance and technology actions exist.
  • The economic, health, and social benefits of sustainable buildings are significant. Buildings provide shelter, places to live, work, learn and socialize, directly affecting our daily lives.
  • Buildings are long-term ventures. Today’s new buildings are tomorrow’s existing stock. Failure to act now will lock in growth in GHG emissions for decades.

Here is how the morning will pan out:

8:30 – 9 Registration and networking
9 – 9:15 Keynote and opening
9:15 – 10:30 Breakout (unconference)
10:30 – 10:40 Break + Networking
10:40 – 12:00 Paris Panel with questions from audience

Both the panel and breakout sessions will focus on the following topics and will provide perspectives from various professional backgrounds:

  • Value Chain Transformation: is the building sector capable of massive deployment of low emitting buildings and deep renovations? How will building sector stakeholders better work together to scale up solutions adapted to local circumstances?
  • Bridging the investment gap: how ready is the finance sector to increase investment in building efficiency?  How will we address the critical need to scale up the public and private financing of EE and sustainable buildings. We will explore how buildings and EE can contribute to realizing MA's carbon goals and how the financial sector can help support that.
  • Public Policies: what is the readiness to implement long term action plans to address the key role of local jurisdictions to organize and facilitate integrated policy packages and collaborative approaches that shift to a low carbon and resilient built environment. 
  • Building rating & reporting systems: how do they support the COP21 momentum?  

Please join us as a community of advocates and practitioners as we explore how to leverage the public awareness and policy momentum generated by COP21 to drive policy gains in Massachusetts.

Hacking LEED v4: Innovation and Performance” at 10am-1pm

How will green building practitioners use the updated and mandated LEED v4 to raise the bar on energy & environmental performance in buildings? At the end of October 2016, the current LEED 2009 system will no longer accept new projects and all projects will be registering in v4. Will you be ready? What point and point complexes will help you through the new maze? How do pilot credits and innovation credits fit? Are you watching how legacy projects registered in v2009 are subject to changing requirements even now? Yes​!​ you have heard all about how LEED v4 is coming. Well, this year it's here and you will be using it. Learn from practitioners who are already waist-deep in the v4 waters.​ Hosted by MA USGBC​.

Building Blocks for Green Master Planning: A Hands-on Introduction to LEED ND” at 2pm-5pm

This engaging, hands-on workshop will give participants a “learning by doing” introduction to sustainable site planning principles and USGBC’s LEED for Neighborhood Development program. The workshop will begin with a short introduction. Then, using case studies developed from actual site designs, participants will complete a series of guided exercises in small teams to develop their own plans for these sites using wooden building blocks on top of the case study site plan. Teams will test development feasibility, do site design, and apply LEED ND credits to their plans. By comparing the workshop team designs and considering the actual plans, participants will explore the many ways that sustainable design principles can be applied to site planning. Teams will also gain experience with applying LEED ND prerequisites and credits to their site plans. This workshop is designed for participants of all skill levels—no prior design or planning experience needed.

Sign up through the links above, which will take you to the BE16 registration page. Then, show up and benefit from these excellent presentations!

A busy week indeed for solar energy, and still more work to be done!

By Anthony Lucivero, Advocacy Fellow


We have seen a flurry of solar energy activity in Massachusetts this past week. The Joint Rule 10 deadline of March 16th is fast approaching, which means all joint committees must report out the bills they have. Otherwise, the bills that remain unreported on will “die in committee” (you might have heard about this in our newsletter). If the joint committee in charge of net metering legislation does not report out the bills dealing with solar energy and net metering, the incredible progress we have made in Massachusetts for renewable energy will be lost. 

The USGBC MA Chapter has announced a “Call to Action” for our members (and anyone reading this!) to send a letter of support for net metering in Massachusetts. This includes: immediately raising the caps on net metering, funding a comprehensive and independent study on the value of solar energy in Massachusetts, supporting the democratization of solar through virtual net metering and community shared solar, and reform the SREC system. 

Please find your local legislator, and fill out this template letter with your information, and then send it via email to them! The chairs of the Joint Committee on Telecommunications, Utilities and Energy also need to hear your voice, so please send a copy to them as well (Senator Benjamin B. Downing and Representative Thomas A. Golden, Jr.).

The fine folks at Nexamp, SEBANE, and CivicSolar are also sending letters to legislators. With your help, this will be an undeniable movement of support for net metering. 

Vote Solar, Sebane & CivicSolar are hosting a Solar Lobby Day next Tuesday, March 8th! Join in to show your support and make your voice heard!

Where and when:

Tuesday, March 8th at 9am, at the State House in front of the Governor's Office (Point A on this map)

Schedule:
9:00am: Meet in front of Governor's office
9:15: Group photo
9:20am: Distribute materials
9:30am – 3:00pm: Meetings with legislators
3:00pm: Rendezvous back at Governor's office

 

 

 

Our Building Tech Forum is April 21st, Save the Date!

By Ryan Duffy, Communications Fellow

Building Tech:

Buildings are fundamentally about technology. Innovation in the building sector is driving improvements in performance and enhancements to the user experience.

Join us April 21st for this exciting investigation in to the intersection of buildings and innovative technology. 

Pathways to Involvement:

The Origins of the Event:

Building tech is the intersection of the innovation economy and real estate. The green building industry is right here in the middle of it – creating new ways to increase the value of real estate and improve the sustainability of our building stock and our communities in general. Buildings are responsible for 30% of greenhouse gases globally, and approximately 40% in the US. Recently, at the COP21 negotiations, the UN convened a “Buildings Day” to explore the ways the real estate sector can support improved environmental performance through better buildings. USGBC is committed to the creation of 5 billion square feet of certified green buildings in the next five years: this will require deployment of technology on a massive scale. The results will be better buildings, healthier occupants, more vibrant communities and a thriving industry connecting technology to real estate. 

 

We at the Massachusetts Chapter are here to champion that effort in our Commonwealth and we need to bring all the parties together.  You can read more about the ambitions of global leaders and recent agreements here. It is an exciting time to be a part of the high performance segment of the building industry!

For All Our Real Estate Pros– A Presentation on the Global Real Estate Sustainability Benchmark (GRESB)

By Ryan Duffy, Communications Fellow


Join us for a presentation on the Global Real Estate Sustainability Benchmark (GRESB) Survey; learn what it is, how it works and where it’s going.  This session will be presented by Laura Barnatt, of TA Realty, and our Existing Buildings Committee.  


The Global Real Estate Sustainability Benchmark (GRESB) was created in 2009 by a team of economists and statisticians from the Netherlands. Co-founded by Nils Kok at the University of Maastricht, GRESB was developed as a way for portfolio managers to more complexly assess real estate assets to uncover greater value for owners.

GRESB is a process of assessment which enables the multi-faceted aspects of property to be tracked over time in greater detail than has ever been done before. Through the GRESB process, an asset is rated in a new way, and the management entity is evaluated in a new way, which creates useful data about the underlying asset. With this data, and with the identification of component processes, asset managers can see into real estate and how non-financial aspects affect their financial performance.

The 2015 survey data highlights global trends and attempts to explain their impact on investors, GRESB survey participants, and the green building market. The 707 Participants–whose institutional capital represents $2.3 trillion of property value–have made many great strides in sustainability since 2014. The in-depth survey focuses on 7 thematic targets. This survey impressively revealed an average improvement from GRESB participants in each category:

Management: 96% have a specific person with responsibility for implementing sustainability objectives
Disclosure & Assurance: 92% report having specific sustainability objectives
Tenant & Community Engagement: 60% now have best-practice lease clauses 
Health and Well-Being: 84% increase in new construction measures to support health and well-being
Climate Risk & Resilience: -3.04% reduction in GHG emissions
Water & Waste: -1.65% decrease in water use
Energy: -2.87% reduction in energy consumption

Register for the event here!

The 2015 annual GRESB Survey includes seven aspects of sustainability spanning management policies to stakeholder engagement:


Buildings are for People: Design Strategies for Occupant Engagement Presinar

By Ryan Duffy, Communications Fellow

About

In this one-hour course, the participant will explore design strategies that encourage beneficial occupant behavior. Consider the impacts occupant behavior changes can have on a building over its lifetime, dispel myths that key occupant behaviors cannot be directed by designers, and learn how these strategies can help achieve LEED certification.

Objectives

  1. Discuss how occupant behavior impacts a building’s environmental performance
  2. Identify design strategies that encourage beneficial occupant behavior in the areas of transportation, energy and water conservation, materials, and indoor environmental quality
  3. Explain how to target strategies by including representative occupants in the design process
  4. Describe how design strategies aimed at occupant behavior can help projects achieve LEED certification
