BOS20-204Building In & Building Out: Lessons Learned from Deep Energy RetrofitsMaine Passive House (MPH) has used two different strategies in retrofitting existing homes. One strategy involves adding insulation to the outside of the building; the other strategy is to add insulation to the inside of the building. Most projects involve a mix of the two strategies. Along with added insulation and eliminating thermal bridging, MPH increases air tightness, installs high performing windows and doors, and adds mechanical ventilation systems in their projects. They use Therm and PHPP to help build cost-effective resilient buildings, most of which are insulated with cellulose and local materials. MHP has done two residential retrofits (close to PH standard) and one commercial retrofit. They will use case studies to discuss lessons learned from the field.BE20 Sessions3/24/2020 8:30-AM3/24/2020 9:30-AMHarbor IAnna Heath , Jesper Kruse Jennifer Hatch AIA 1.0 LU/HSWBPI 1.0 hourGBCI BD+C, ID+C, WELL 1.0 hourMA CSL 1.0 hour, EnergyPHI 1.0 credit2 (some prior experience/knowledge helpful)Summarize the general principles behind two different walls systems and two different roof systems that can be used in retrofit projectsCompare and contrast two different strategies for constructing airtight assemblies in a retrofit projectApply two different strategies to add mechanical ventilation to retrofit projectsDescribe the benefits of using cellulose insulation for insulation, and membranes for airtightness, in retrofit projects

BOS20-B5Tepid WaterSPONSORED BY EEMAX - Tepid Water is directed to the commercial safety eye wash, face wash and drench shower systems (labs, schools, medical, manufacturing, chemicals). Considering the vast number of situations that involve handling hazardous chemicals and materials during the normal course of business, architects need to be acutely aware of the impact on infrastructure design and specifications surrounding emergency equipment. Understanding the minimum requirements for compliance that is dictated by the Occupational Safety and Health Administration (OSHA) is a crucial first step in this design process. In addition an understanding of tepid water, as defined by the American National Standards Institute (ANSI) code Z358.1, and methods for best practices in the delivery of tepid water, will help the architect to design a more effective and efficient building infrastructure that is required to support any necessary emergency equipment. This session presents current OSHA and ANSI standards as they relate to tepid water, with an overview and comparison of current water heating technologies.Sponsored by:BE20 Sessions8/12/2020 3:00-PM8/12/2020 4:00-PMBurroughsChris Anderson , Randy Weidig AIA 1.0 LU/HSW through Eemax2 (some prior experience/knowledge helpful)Understand the requirements of OSHA 29 CFR 1910.151(c) Medical Services & First Aid and ANSI Z358.1 standardsExplain the risks and dangers of non-compliance to these standardsExplain the importance of tepid water to an emergency response situation, the risk and danger of scald as well as hypothermiaCompare methods of compliance and develop best practices for selecting a water heating solution based on the application and overall system design
BOS20-103We're Still Green at Being Green! Lessons Learned on the PathIn today's climate crisis, it's imperative to change the way we design and build in order to reduce or eliminate carbon emissions. However, some of these changes to building design can introduce unanticipated side effects. We can minimize these side effects on future projects by learning from each other - we all have insights that we've gleaned from our own projects. This presentation is a collection of lessons learned on the path to better performing buildings. Let’s share! Topics include wood vs. steel studs, incorporation of thermal breaks, reduction of Portland cement and concrete volume, and air barrier pitfalls.BE20 Sessions8/13/2020 8:00-AM8/13/2020 9:00-AMMarina IJim D'Aloisio , Jodi Smits Anderson Jennifer Hatch AIA 1.5 LU/HSWBPI 1.5 hoursGBCI BD+C, ID+C, WELL 1.5 hoursMA CSL 1.5 hour, Energy 2 (some prior experience/knowledge helpful)Identify installation problems with different types of air barrier systemsIdentify thermal problems with conventional cold-formed stick-type constructionContrast installation issues of conventional foundations and frost-protected shallow foundationsExplain how lack of proper maintenance of porous pavement systems can lead to premature demise
BOS20-223Solar & Storage: Making Commercial Retrofits Pay Off in MassachusettsWe will present new analyses showing how commercial facilities in Massachusetts (and beyond) can maximize energy savings and resiliency by installing solar + electric storage systems. We will review and explain how to take advantage of a suite of incentives and revenue streams including the SMART solar incentive with storage adder, the new energy efficiency performance incentive, the federal investment tax credit (ITC), demand charge management, and net metering. This will help Massachusetts building owners understand how the incentives and opportunities for solar+storage systems interact, how “value stacking” works (and when it doesn’t), how to optimize system sizing and operations, and how systems pencil out in real economic terms, using real existing commercial buildings as examples. Finally, we will address common barriers in financing, interconnections and metering. This presentation will be discussing the results of two reports scheduled to be published in the fall of 2020.BE20 Sessions8/13/2020 8:00-AM8/13/2020 9:00-AMMarina ITodd Olinsky-Paul , Geoff Oxnam Kurt Roth AIA 1.0 LU2 (some prior experience/knowledge helpful)Summarize the solar and storage incentives available through existing Massachusetts programs, and how to stack incentives List the variables that determine the building economics of solar+storage systems, including load curves, utility demand rates, tax appetite and locationExplain markets and revenue opportunities including net metering, capacity markets, demand charge management, demand response and energy arbitrageDescribe tools to help building owners estimate the economic profile of a solar+storage system, and how to size a system to meet the needs and capacities of the host facility

While this technology is remarkable in its affordability, efficiency, and ability to offset a major contributor to greenhouse gas emissions, there are often unmet challenges in selecting the most appropriate piece of equipment. This session will explore the equipment options available in 2020 and evaluate design strategies to ensure that the equipment can be successfully deployed in new construction and retrofit applications.BE20 Sessions8/13/2020 8:00-AM8/13/2020 9:00-AMMarina IIDana Fischer , Michael Simons Michael Simons AIA 1.5 LU/HSWBPI 1.5 hoursGBCI BD+C, ID+C, O+M 1.5 hoursMA CSL 1.5 hour, Energy2 (some prior experience/knowledge helpful)Determine the suitability of different types of ASHP equipment in a wide variety of buildingsExamine how room, block, and design load inform ASHP equipment selectionDemonstrate Solar PV’s impact on GHG emissions & operating cost when paired with ASHPsInvestigate the effects of selecting multi-zone ductless vs ducted ASHPs
BOS20-104Scalable Multifamily Retrofits: Case Studies from Energiesprong & Two US PractitionersEnergiesprong and practitioners selected by RetrofitNY are developing standardized and scalable methods to achieve whole-building near-zero energy retrofits while maintaining multifamily tenants in place. Energiesprong, based in Europe, has successfully transformed 4,500 affordable units and RetrofitNY is currently in proof-of-concept phase.  The session will provide an introduction to standardized retrofits for multifamily housing, an overview of the best practices in Europe, and the practical implementation in the US market. Two case studies by US practitioners participating in NYSERDA’s RetrofitNY program will focus on the design process, off-site panelization, the use of laser scanning, construction cost, and funding requirements. The first is a wood-framed 24 unit building employing a panelized approach and the second is a four-story masonry building that will receive a high-R EIFS exterior and high-performance HVAC.BE20 Sessions8/13/2020 9:15-AM8/13/2020 10:45-AMHarbor IChris Benedict , Margo Valdés , Ian Shapiro Stephanie Horowitz AIA 1.5 LU/HSWMA CSL 1.5 hours, EnergyAICP (American Planning Association) 1.5 hours2 (some prior experience/knowledge helpful)Explain the urgency of high-performance retrofits and the role of the affordable housing sector as a beachhead marketDescribe off-site retrofit strategies for the affordable multifamily housing sectorIdentify what is needed to realize and scale high-performance multifamily retrofits in the US marketRecognize trade offs required to meet both budget and performance in a multifamily high-performance retrofit
BOS20-105Beautiful Day in the Neighborhood: How We Achieve Massive Home-scale Climate ActionsUrgent climate goals require state programs such as Mass Save to better target comprehensive decarbonization – applying efficiency, electrification, demand response, and solar+storage – in an equitable manner that addresses differences in local building characteristics. Meanwhile cities and towns, including low income/urban, suburban, and rural communities, are making commitments to local climate neutrality and social equity for their citizens. The panel and audience will discuss how communities could achieve these with localized information, simplified processes, and improved retrofit economics, as many have done before with their Solarize initiatives. The panelists will discuss enabling community-based services now being deployed that foster high carbon impacts, such as MassEnergize, EnergySage, and All InEnergy, as well as potentially supportive state program ideas.BE20 Sessions8/13/2020 9:15-AM8/13/2020 10:45-AMMarina IVVikram Aggarwal , Rouwenna Altemose , Harvey Michaels , Ellen Tohn John Livermore AIA 1.5 LU/HSWAICP (American Planning Association) 1.5 hour1 (no prior experience/knowledge needed)Explain how community-driven Solarize Mass programs have produced 3 to 10 times higher program penetration by lowering consumer costs, reducing time and risks, providing trusted local support and personal recognitionDescribe nascent local tools and services developed and provided to foster high carbon impacts in both low income/urban and suburban communities (and in so doing, attendees may explore opportunities to pursue business and career opportunities in the community climate arena)Advocate for the advantages of changing policies towards programs targeting comprehensive decarbonization in a manner that addresses local values and building characteristics, over statewide "one size fits all" program modelsExplore how this local, comprehensive approach may improve retrofit economics for consumers, and increase social equity, while helping us reach the penetration necessary to achieve our climate goals

BOS20-222Passive House Ventilation: Humidity Considerations in Multifamily Residential BuildingsThe Passive House concept continues to scale up in North America, in both number and size of projects. Passive House buildings benefit from airtight construction, as minimizing winter infiltration directly lowers energy consumed when heating the building. Airtight construction also hinders airborne moisture from escaping through the building skin, thus requiring new thinking about the requirements of the ventilation system. This session examines the causes and solutions to humidity buildup in Passive House buildings and is for those interested in learning how to achieve peak energy performance from their ventilation system while minimizing the risk of excessive moisture buildup.BE20 Sessions8/13/2020 3:00-PM8/13/2020 4:00-PMHarbor IIIMike Woolsey Keirstan Field AIA 1.0 LU/HSWBPI 1.0 hourGBCI BD+C, ID+C, WELL 1.0 hourMA CSL 1.0 hour, EnergyPHI 1.0 credit2 (some prior experience/knowledge helpful)Describe the sources of indoor humidity in multifamily residential buildingsDetermine the best method of managing humidity in airtight buildingsUnderstand the impact of airtight construction on heating energy useDescribe in basic terms the different types of systems used to ventilate airtight buildings
BOS20-225Seeking Perfection in Air-SealingThe invention of the blower door was an important step in minimizing thermal losses from buildings.

BOS20-203'We Went LED' is Not Sufficient: The Place of Lighting in Our Low-Carbon FutureWe're over ten years into the LED revolution, but mythology still motivates decision-making. Energy professionals need to know that "let's just go LED” leads to sub-optimal results. LED efficiency varies greatly, even within EnergyStar or DesignLights Consortium listings. As we’ll discuss, variance is at least 40% and up to 80%. Amazing federal programs that helped modulate the LED industry and track it are suddenly gone, so how do we judge? Smarter controls (and/or technicians) offer huge potential for commercial/industrial, but are still a challenge in residential. After a phenomenal success (57% drop nationally in energy for residential lighting 2001-18), there are still substantial savings available, and lighting loads will persist in low-carbon buildings. We'll also report the latest in inane “light bulb wars.”BE20 Sessions8/14/2020 8:00-AM8/14/2020 9:00-AMMarina IIIFred Davis Fred Davis AIA 1.0 LU/HSWBPI 1.0 hourGBCI BD+C, ID+C, O+M, WELL 1.0 hourMA CSL 1.0 hour, Energy1 (no prior experience/knowledge needed)Differentiate (using tools discussed) between standard LED fixtures and the most efficient LED fixturesSpecify highest efficiency lighting fixtures so as not to lose 40-80% savings opportunities.Appreciate the 57% drop nationally in energy consumption for residential lighting 2001-18.Understand the potential impact of lighting control options (when appropriate).

BOS20-102To Electrify or Not to Electrify...?Should we be trying to electrify everything? Is it practical for existing and new buildings with the technologies we have now? Two engineers with different takes on these questions will debate electrifying residential buildings, from small single-family to high-rise apartments. Both speakers have years of experience with heat pump technologies (mini-splits, PTHPs, water-source HPs, VRF, and several types of heat-pump water heaters). They’ll present examples of buildings where these systems worked wonderfully, where performance was less than ideal, and a few absolute failures. Too often, building professionals – designers, engineers, contractors, building owners/operators, utilities, and even manufacturers – don’t fully understand how these new systems work.

BOS20-209Testing Intuition: Re-evaluating Transformative Reuse ProjectsAs architects, designers, builders, and community advocates, we value the adaptive reuse of buildings, but lack data to verify our design choices. We often operate on intuition to choose what to reuse and what to upgrade, attempting to balance life cycle impacts of new construction materials while lowering operational energy use. Over the last decade, Boston firms Bruner/Cott and Goody Clancy have evolved their practices in high-performance and transformative reuse to think more deeply about the embodied and operational impacts of reuse projects. We’ll look back at four projects’ design strategies for life cycle impact reduction and present retrospective life cycles.

BOS20-216Unvented Roofs without Spray Foam: The Rest of the StoryBack in 2016, our team started a multiyear experiment, sponsored by Building America, on unvented roofs without spray foam or exterior rigid insulation, using an instrumented test hut with multiple test bays. The experiment examined cellulose vs. fiberglass insulation, interior vapor control membranes, diffusion vents at the ridge, interior humidification, inward vapor drive issues, and the effect of air barrier imperfections. Some preliminary results were presented at BuildingEnergy Boston in early 2018. After three winters of experimentation, this is the rest of the story. We will give our take on what works, what is too risky, and what you might be able to get away with some of the time.BE20 Sessions8/14/2020 3:00-PM8/14/2020 4:00-PMHarbor IKohta Ueno Rachelle Ain AIA 1.0 LU/HSWBPI 1.0 hourMA CSL 1.0 hour, Energy2 (some prior experience/knowledge helpful)Explain the moisture risks inherent in unvented/compact roof assemblies with fibrous (air‐permeable) insulationDefine the roles that vapor diffusion and air leakage have on moisture levels in roofsExplain the role that a vapor diffusion vent can have in ameliorating roof moisture risksDescribe the risks of inward vapor drive in unvented roof assemblies
