We continue with this reality: whether your home, workplace and neighborhood are well lighted depends on your social, economic, and environmental status. Keynote speakers Edward Bartholomew and Mark Loeffler will lead us to the next evolution of sustainable lighting design viewed through the lens of environmental justice. They’ll describe historical precedents and current realities, share case studies of how lighting reinforces power and status, and reveal how quality lighting and quality darkness are essential for well-being. This keynote is designed for everyone who works in the built environment and will transform the way you think about how light (and dark) touches every aspect of the work we do. Prepare to be enlightened. Light equity is a new concept for many in the NESEA community, and we know this presentation will generate many questions. To address those questions and help you integrate the concepts presented, we are offering a live Q&A with the keynote speakers on Thursday, May 6 at 1:30pm. ||BE21 Sessions||5/5/2021 10:30-AM||5/5/2021 11:30-AM||Edward Bartholomew , Mark Loeffler ||Christopher Nielson ||AIA 1.0 LU/HSW||1 (no prior experience/knowledge needed)||Explain how quality lighting is used as a signifier of power, status, and privilege and has been denied to marginalized communities.||Identify historical precedents that led to lighting being used as a tool of surveillance, policing, and the control of nocturnal behavior.

|BOS21-601||Achieving Performance Goals: Modular New vs. Retrofit Existing||Two very different projects – Oak Bluffs Town Hall and The Graphic Lofts – share a common goal to create a passive-house-inspired high-performance building. One building utilizes conventional construction techniques, the other building employs off-site construction strategies. These case studies will review decisions made and lessons learned following each project’s approach. The speakers will compare and contrast the challenges and benefits of on- and off-site construction to realize this common goal. We will discuss early design decisions, performance strategies, and construction details for each project, identifying areas of cross-fertilization between stick-built and modular projects. We will reflect on our experiences in the hope that you will find them valuable as you evaluate your next building opportunity.||BE21 Sessions||5/6/2021 8:00-AM||5/6/2021 9:00-AM||Ned Collier , Kendra Halliwell ||Arlen Li ||AIA 1.0 LU/HSWBPI 1.0 hourMass.

The project team sought practical, low cost, and reproducible solutions to meet project goals of net zero energy, minimizing embodied carbon, and electrification. We aspire to broaden the toolset of owners, designers, and builders by sharing our approaches to permit approval, structural design, building envelope, window specification and installation, and HVAC. Local zoning regulations and a non-conforming existing structure proved to be major obstacles to desired envelope upgrades. We will suggest methods of navigating zoning constraints to attain a net zero energy remodel.||BE21 Sessions||5/6/2021 8:00-AM||5/6/2021 9:00-AM||Frank Dill , Jonathan Kantar , Woodbury Swan , Marjorie Woodwell ||Richard Lo ||AIA 1.0 LU/HSWBPI 1.0 hourMass.

|BOS21-603||Comparing the Operating Performance of High Performing Public Buildings to their Design||High performing buildings consume considerably less energy and water than conventional buildings. Through energy modeling and water use projections, design teams have been able to calculate the amount expected to be saved during the design phase. However, not much has been done to circle back and compare these projections to actual performance. This pilot study compares actual operating results to predicted in 21 public buildings in Massachusetts to learn how accurate these projections are. The study also interviewed Town staff including facility managers to learn about problems faced and lessons learned during the initial years of a school or library’s operation to inform new projects moving forward.||BE21 Sessions||5/6/2021 8:00-AM||5/6/2021 9:00-AM||Marie Nolan , Christopher Schaffner ||Ksenia Ruuska ||AIA 1.0 LU/HSWBPI 1.0 hourGBCI LEED BD+C, ID+C, O+M 1.0 hourConference-day attendance credits available from PHIUS, RESNET, and Mass.

|BOS21-604||Understanding Boston's Proposed Performance Standard||Boston’s proposed building emissions performance standard would set carbon emissions targets for existing large buildings that decrease over time. The targets align with the City’s 2030 goal of a 50% reduction in emissions from 2005 and its 2050 goal of net zero emissions. Participants will learn about the policy's foundation in equity and transparency; how the City has worked closely with the community, stakeholders, and experts throughout an iterative design process; lessons learned from other cities with similar policies; and what the performance standard would mean for building owners, contractors, and green jobs. Alison Brizius, Boston’s Director of Climate and Environmental Planning, will also share case studies for how different types of buildings could achieve the targets. The second half of the session will be devoted to breakout discussion groups focused on areas of the policy that still have open questions or merit ongoing discussion around implementation.||BE21 Sessions||5/6/2021 9:30-AM||5/6/2021 11:00-AM||Alison Brizius ||Meg Howard , Daryl Wright ||AIA 1.5 LU/HSWBPI 1.5 hoursConference-day attendance credits available from PHIUS, RESNET, and Mass.

They are adjacent to each other in the Rockaways in NY (in the flood zone) and were completed two years apart. Although they look almost identical, they are very different under the hood. Each has a different structure, envelope (ICF vs Block), ventilation strategy (Unitized vs Centralized), and heating and cooling system (VRF vs. ground source heat pumps) along with several other differences due to changes in city regulations and varying site conditions. Mark Ginsberg (Architect) and Lois Arena (Energy / Passive House Consultant) will present the details of these two buildings, what we have learned and how the developments are performing in an effort to develop best practices for highly energy efficient, multifamily design and construction.||BE21 Sessions||5/6/2021 9:30-AM||5/6/2021 11:00-AM||Lois Arena , Mark Ginsberg ||Greg Smith ||AIA 1.5 LU/HSWMass.

|BOS21-611||Virtual Power Plants: The Future of Distributed Energy Storage||The virtual power plant - aggregated, behind-the-meter solar, energy storage, and building loads dispatched in concert to meet grid needs - is a new model that has been pioneered in New England and is now being adopted by forward-looking utilities and policymakers across the country. This session will explain why the virtual power plant is the future of energy storage, how states can create virtual power plants using existing programs and budgets, and why this is an important new paradigm that will benefit customers and communities. The virtual power plant model solves numerous problems, including how to fund distributed storage and bring it to scale; how to democratize storage, and include low-income and underserved communities in the storage revolution; how to lower storage investment risk for customers, utilities, investors and policymakers; how to tie individual, BTM systems to regional grid needs; and how to provide resilient power to communities for free. The adoption of a simple funding model, which uses existing state programs and budgets, makes possible the development of pipelines of behind-the-meter energy storage projects, including in low-income communities, which need advanced clean energy systems the most.||BE21 Sessions||5/6/2021 11:30-AM||5/6/2021 12:30-PM||Todd Olinsky-Paul , Geoff Oxnam ||Kurt Roth ||AIA 1.0 LUConference-day attendance credits available from PHIUS, RESNET, and Mass.

Retrofit Lessons from Low-Income Multifamily Projects||Many cities in New England and beyond have carbon neutrality goals and are actively addressing new construction to hit the goals. What about all the existing buildings? How will those be addressed to reduce energy and carbon? What creative enclosure approaches can be used to achieve these goals? Preservation of Affordable Housing has new construction projects in design to PHIUS standard. POAH also has rehab projects that never hit a passive house standard but go as deep as possible. Through review of existing projects and building data, this session will explore what we have done, what we learned from this, and make recommendations for other developers and designers. ||BE21 Sessions||5/6/2021 11:30-AM||5/6/2021 12:30-PM||Julie Klump ||Danny Veerkamp ||AIA 1.0 LU/HSWBPI 1.0 hourMass.

|BOS21-613||The Next Frontier: Material Transparency Across Disciplines||Transparency is the foundation for making informed decisions about the products we specify. The AEC industry is familiar with sustainability goals related to energy efficiency, but holistic discussions related to material goals across the entire team are still rare. Large strides have been made in interior product disclosure, but much less so for building envelope, MEP and lighting systems. Without transparency our ability to quantitatively convey the magnitude of decisions made across the project team, and track progress as the design progresses, is limited. This panel will highlight the importance of product disclosure so a meaningful building LCA can be conducted, and the health and wellbeing impacts can be evaluated. Target areas for each discipline will be given as a way to focus discussion for goal setting and project kick-off meetings, and resources related to material transparency will be shared. ||BE21 Sessions||5/6/2021 1:30-PM||5/6/2021 3:00-PM||Laurel Christensen , Alexandra Gadawski , Melissa Mattes , Alejandra Menchaca ||Trisha Parekh , Margo Valdés ||AIA 1.5 LU/HSWBPI 1.5 hoursGBCI LEED BD+C, ID+C, WELL 1.5 hourMass.

|BOS21-614||Project Management from Afar||Project management from a remote location is common to some and unfamiliar to others. For those previously unfamiliar, Covid-19 has accelerated the industry’s transformation towards remote management becoming the norm. For those with experience, there is always room for improvement to both avoid pitfalls and maximize the success of the project. As our building envelopes get tighter and we aim to reduce our embodied and operational carbon footprints, our documentation, communication, and management need to keep pace to reduce risk, ensure happy clients, and enjoy the process. Do you have an amazing potential project...1000 miles away? Can you manage, let alone design, without setting foot on site? Does a project need to reduce overhead in order to make the fee proposal successful? Is there a client who doesn’t want to pay for CA? How do you manage expectations “digitally”? Are there tricks for avoiding problems before they materialize? The panelists will speak about techniques and lessons learned from all phases of the design and construction process on a range of projects from single family Passive Houses to international skyscrapers. If you play an active role in managing a project, regardless of your sector within the industry, this session is for you! ||BE21 Sessions||5/6/2021 1:30-PM||5/6/2021 3:00-PM||Tia Garcia , Matt Genaze , Meghan Hawkins , Chris Johns , Seanna Walsh ||Maria Washington ||AIA 1.5 LUMass.

Unfortunately, over the past five years, we have received calls from multifamily building owners who are battling persistent summertime humidity problems. Comfort complaints, sweating ductwork, waterlogged drywall, and mold on furnishings, clothing, registers . . . you name it. We will discuss how we went about these investigations and the tools we used to diagnose these issues. When investigating these problems, unfortunately, there was no ‘magic bullet’ or single cause that we could pin down: it was often a perfect storm of factors. From air conditioner sizing vs. cooling load, to poorly configured cooling systems, to outside air ventilation system problems, to catastrophic air leaks - we will look at them all, and discuss how to identify and fix these issues.||BE21 Sessions||5/6/2021 3:30-PM||5/6/2021 4:30-PM||Kohta Ueno ||Keirstan Field ||AIA 1.0 LU/HSWBPI 1.0 hourMass.

Focusing on finding scalable and replicable models for building typologies, such as triple deckers, will help reduce greenhouse gas emissions, as well as increase tenant comfort and reduce energy bills. This session focuses on the best ideas and lessons learned from MassCEC’s Triple Decker Design Challenge. What variations were there in proposals for roofs, basements, exterior insulation, air infiltration reduction, electrifying mechanical systems, and sizing of solar systems? When upfront cost and 30-year operating cost are factored in, what are the most promising actions that should be taken? We'll hear details from MERGE Architects, Inc., who submitted a prizewinning proposal to add a unit to the back of a triple decker, and finally, hear about the City of Boston's greenhouse gas emission goals, housing shortages, and how retrofits of triple deckers are critical to these goals.Sponsored by:||BE21 Sessions||5/6/2021 3:30-PM||5/6/2021 4:30-PM||Jacqueline Guyol , Soo Jin Yoo , Taylor Cain ||AIA 1.0 LU/HSWConference-day attendance credits available from PHIUS, RESNET, and Mass.

Previous NESEA sessions by JS Rancourt have discussed HFC refrigerants, including at Building Energy Boston 2020 (click here to view this presentation, and to gain an understanding of the chemistry, safety, codes and standards around HFC refrigerants).This presentation will build on previous presentations, digging deeper into regulatory updates around potential HFC phase-downs in the U.S. The inclusion of the AIM act in the COVID relief legislation passed by Congress on Dec 21, 2020 provided the EPA with authority to start planning a Federal level phase down of HFCs, to align the U.S. with the global Kigali amendment. Though the EPA has until the end of the year to provide direction, the language in the AIM act, as well as precedence from existing State level regulations, allows for some predictions to be made. The evolution of ASHRAE and UL standards affecting ASHPs and VRF will also be discussed, including what has changed so far to help introduce lower GWP refrigerants, and what changes are still necessary.JS will also share some recent research work evaluating the life cycle emissions of buildings, and the importance of estimating refrigerant emissions versus other contributors such as embodied carbon, and operating emissions from heating, cooling, ventilation and domestic hot water. Having a holistic understanding of a building’s lifetime climate impact, or at least between now and 2050, is key to making the right design and technology decisions for new construction and retrofit projects today.Sponsored by:||BE21 Sessions||5/7/2021 8:00-AM||5/7/2021 9:00-AM||JS Rancourt ||AIA 1.0 LU/HSWBPI 1.0 hour4.5 credit-hour packets available from PHIUS, RESNET, and Mass.

|BOS21-712||The Glue That Binds PrePHab: How Designers & Builders SIMMplify Passive House||The typical picture of prefabrication – a panel being positioned by crane – belies the tremendous amount of required planning and interdisciplinary coordination. Single Integrated Manufacturing Modeling (SIMM) and off-site prefabrication work together as the glue that binds this collaboration. Where many educational programs focus on the rapid installation and production benefits of prefabrication, this session emphasizes the coordinated up-front approach. This innovative approach capitalizes on production methods to support collaboration and clash detection while enabling the most complex architectural designs and geometries. Two very different Certified Passive House projects will illustrate the journey. The projects, different dramatically in scope and aesthetics – traditional vs. modern – demonstrate the ease with which the approach can be transferred. Project architects and construction teammates will share how prefabrication and SIMM enable stakeholder voices to be heard, minimize risk, and support high-performance building, making low-carbon and Passive House results accessible to any owner, builder, or architect.||BE21 Sessions||5/7/2021 9:30-AM||5/7/2021 11:00-AM||Ilka Cassidy , Chris Hearl , Steve Hessler , Kyle Macht , Shannon Pendleton ||Richard Lo ||AIA 1.5 LU/HSWMass.

|BOS21-703||Piloting, Scaling & Committing to Healthier Materials||When it comes to toxic chemicals, there is an urgent need for market transformation. Occupants, tradespeople, and fence line communities are being contaminated by the chemical manufacturing industry, which raises concerns about environmental racism and injustice. We can support these communities by reducing and eliminating classes of chemicals from our buildings. This session presents four entities who have stepped up to the challenge: MIT, Colby College, Shepley Bulfinch, and Thornton Tomasetti. Panelists will share their stories of what led them to examine material decisions and the internal challenges to organizational engagement and commitment to healthier alternatives, with the goal of creating market demand for healthier products.||BE21 Sessions||5/7/2021 9:30-AM||5/7/2021 11:00-AM||Sandy Beauregard , Amanda Garvey , Nicole Imbergamo , Siiri Julianus ||Greg Smith , Danny Veerkamp ||AIA 1.5 LU/HSWBPI 1.5 hoursMass.

|BOS21-705||Integrating Sustainability into Practice||The year 2020 marked the 50th anniversary of Earth Day, a decade until major carbon emission goals, and the first year of the AIA Framework for Design Excellence. There is no better time to take stock of your firm's sustainable design practice, whether you have been doing this for decades or just starting out. The design community is truly in this together and sharing is critical. This session will provide lessons learned from small, medium, and large size Boston firms on how to integrate sustainable design holistically and successfully into practice. Topics to be explored are firm leadership, firm organization, project implementation. An interactive audience exercise will also provide attendees with a bonus collaboration tool which can be used in any group meeting or workshop.||BE21 Sessions||5/7/2021 9:30-AM||5/7/2021 11:00-AM||Katherine Bubriski , Kristen Fritsch , Alison Nash ||James Cater ||AIA 1.5 LU/HSWMass.

|BOS21-706||Low-Carbon Concrete & Steel Structures||The carbon emissions associated with the production of concrete and steel are significant contributors to the climate crisis, but these materials will remain over the next decade when much of the greatest reductions in greenhouse gas emissions must be made to avoid the worst effects of climate change. Structural engineers can directly influence the emissions related to these materials on their projects through design and procurement optimization and best-practices. Often, however, the most effective solutions to reduce the carbon “embodied” in these products are not always obvious. This session provides an overview of the origins of embodied carbon associated with the production of concrete and steel. Drawing on lessons-learned from practice and a year-long research-and-development study, Thornton Tomasetti has compiled actionable steps that industry professionals can take to make significant embodied carbon reductions in typical concrete- and steel-framed building projects. The presenters will review the manufacturing processes and typical energy use profiles of concrete and steel products, and provide examples of how to use that knowledge to reduce embodied carbon of these materials. At the end of the session, participants will be able to return to work with the knowledge to make embodied carbon reduction in concrete and steel scalable. ||BE21 Sessions||5/7/2021 9:30-AM||5/7/2021 11:00-AM||Jonathan Ellowitz , Patrick Kenny , Emma Reif , Brenda Stern ||Christopher Nielson ||AIA 1.5 LU/HSWMass.

|BOS21-710||Modular vs. Stick-built: A Side-by-Side Comparison with Habitat for Humanity||Pioneer Valley Habitat for Humanity, Simple City Studio, and VEIC present PV Habitat’s award-winning experiment in affordable net-zero housing. Using data from a recent build, PV Habitat compares build time, cost, and energy efficiency between modular and stick-built construction, focusing on the trade-offs between affordability and energy efficiency, and examining where design can simplify or complicate a build. At the cutting edge of affordable housing, these recent builds expand on PV Habitat’s efforts to build small, durable, and affordable homes, and demonstrate that a home does not have to be expensive to be innovative and energy-efficient. Learn how small, durable, zero net energy homes can pave a way to the future of affordable homeownership, where energy efficiency radically reduces utility bills and well-designed small homes offer sufficient, flexible spaces for a variety of family sizes.||BE21 Sessions||5/7/2021 11:30-AM||5/7/2021 12:30-PM||Brien Tal-Baker , Megan McDonough , Li Ling Young ||Stephen Stuart ||AIA 1.0 LU/HSWBPI 1.0 hourMass.

|BOS21-707||Leaving the Mesozoic Behind: From Fossil Fuels to the Future via Carbon-Neutral Buildings||New York State’s carbon-neutral policies and on-the-ground programs are the leading edge in the Northeast and provide a model for all communities. Come be informed and inspired by NYSERDA’s upcoming Carbon Neutral Buildings Roadmap. As part of Governor Cuomo’s Green New Deal for New York, NYSERDA has been spearheading the development of an overarching framework for decarbonizing New York’s buildings by 2050. This presentation will outline the policies and programmatic areas that will achieve radical reduction in the carbon emissions of buildings. Solutions include envelope and other energy conservation measures, smart controls and load shifting, electrification, and onsite storage and generation to drive deep efficiency across varying building sectors, typologies, and geographies. This session will describe the Roadmap’s policy priorities and coordination with New York’s Climate Action Council.||BE21 Sessions||5/7/2021 11:30-AM||5/7/2021 12:30-PM||Greg Hale , Sadie McKeown ||Bryan Evans , Beverly Craig ||AIA 1.0 LU/HSWBPI 1.0 hourConference-day attendance credits available from PHIUS, RESNET, and Mass.

|BOS21-708||Today's Acceptable Ventilation is Unacceptable||Current ventilation standards are based on odor instead of health. One cannot smell healthy air. Ventilation standards disfavor air quality in smaller residences and multi-family dwellings while excessively ventilating larger homes. Ventilation impacts our health, cognition, sleep, and disease transmission. This session provides background on today's ventilation standards and recommendations for creating healthy indoor environments. The Covid Safe Space IAQ calculator for reducing SARS-CoV-2 transmission in buildings is introduced. Examples show reduction of infection probability and infection multiplication with increased fresh air, improved air filtration, face mask usage, and vaccination in different building venues (classrooms, restaurants, offices, gyms, homes).||BE21 Sessions||5/7/2021 11:30-AM||5/7/2021 12:30-PM||Ty Newell ||Mark Schow ||AIA 1.0 LU/HSWBPI 1.0 hourMass.

|BOS21-709|| Decarbonization of Domestic Water Heating in Multifamily Buildings ||Domestic hot water doesn’t get the attention it deserves, so this session will be talking about nothing but it! Decarbonizing DHW in multifamily settings is full of challenges, especially in a heating-dominated cold climate. We will be discussing decarbonization strategies from new construction and existing buildings, central and decentralized systems, and touching on adjacent topics like loads and futureproofing. The presenters will share their perspectives on the pros and cons of different DHW product types and system architectures, as illustrated by real-world case studies highlighting the performance, cost, and reliability of different systems.||BE21 Sessions||5/7/2021 11:30-AM||5/7/2021 12:30-PM||Nicole Ceci , Dylan Martello ||Kurt Roth ||AIA 1.0 LU/HSWBPI 1.0 hourGBCI LEED BD+C, ID+C 1.0 hourMass.

|BOS21-711||Historic Buildings & Climate Change Mitigation: Case Study of a Low-Carbon Renovation||Retrofitting vacant and underutilized historic buildings to PHIUS standards leverages an existing building’s embodied carbon, which combined with low carbon and carbon storing materials, can transform our historic buildings into carbon sinks. With careful consideration, the Federal Historic Tax Credit program can provide an additional source of funding for these ambitious Passive House projects. Currently under construction, Moran Square is one of the first PHIUS Historic Tax Credit projects in the US. The site includes a historic firehouse, a vacant lot, and historic three-story building. Our team is retrofitting the two historic buildings and constructing a new five-story building on the vacant lot. To push it a step further, this 44-unit affordable project is using low-carbon materials during construction. During this presentation, we will share this project’s technical enclosure details, photos of construction, and stories from the field. We will also illustrate how we managed to meet rigorous historic requirements of the Federal Historic Tax Credit program, while achieving ambitious PHIUS and low carbon construction goals.||BE21 Sessions||5/7/2021 1:30-PM||5/7/2021 3:00-PM||Heather Clark , Andy Poshadel , Jacob Racusin , Kohta Ueno ||Lauren Baumann ||AIA 1.5 LU/HSWBPI 1.5 hoursMass.

|BOS21-713||Leveraging Diversity to Meet the Climate Challenge||We cannot achieve the Green Building targets for reducing carbon emissions with the current workforce. We need to rapidly increase the number of individuals in green building fields - designers, green building professionals, engineers, general contractors, envelope consultants, as well as qualified electricians, plumbers, and heating, ventilation, and air conditioning (HVAC) tradespeople who can install heat pumps and solar systems. More diverse employees and more minority, women, and disadvantaged owned companies to hire, collaborate with, and refer will place businesses in the best position to meet the increasing demand.

Do gatekeepers scoff at your requests and ask for “more data”? What if your data could clearly show the value unlocked by energy upgrades? Take an in-depth, hands-on look at how two mission driven lenders, the Connecticut Green Bank, a quasi-public state agency, and Capital for Change, a Community Development Financial Institution (CDFI), developed performance monitoring reports for a set of energy loans to multifamily properties. The data demonstrate how smart energy improvements result in significant energy and operating cost savings that can fund other building improvements or be used for other purposes. The presentation and audience exercises will examine key decision points from the report development process, walk through procedures for portfolio analysis, describe marketing strategies resulting from the work to date, and build your capacity to monitor and sell your own projects and loans. This session is aimed at capital providers and portfolio managers who want to make sure they are investing wisely; owners and advocates seeking creative ways to improve the efficiency, comfort, safety, and resiliency of their properties; and policy makers and public officials needing to leverage scarce public dollars into effective programs. ||BE21 Sessions||5/7/2021 1:30-PM||5/7/2021 3:00-PM||Nate Taylor , Brian Sullivan ||Julia Nugent ||AIA 1.5 LUConference-day attendance credits available from PHIUS, RESNET, and Mass.

When that builder is Jesper Kruse, owner of Maine Passive House, you know remarkable energy efficiency will be the outcome. And when that house is the one Kruse himself built 20 years ago - the first house he ever built - well, you know it’s going to be an especially interesting adventure in single family retrofits. Kruse will explain why he decided to undertake this project. He’ll share step-by-step how he upgraded the envelope, from foundation to roof, and why he chose the new mechanical systems. He’ll offer data: the before and after utility costs, comparing project timeline anticipated versus actual, and the project costs. In this session, you’ll gain practical know-how for retrofits and understand how EnerPHit standards can guide and inspire builders toward passive house results.||BE21 Sessions||5/7/2021 3:30-PM||5/7/2021 4:30-PM||Jesper Kruse ||Anna Heath ||AIA 1.0 LU/HSWBPI 1.0 hourMass.

|BOS21-716||The Proof is in the Project: Cost & Performance of Built Passive Multifamily||With many states incentivizing housing built to the Passive standard, everyone wants to know: are Passive-certified multifamily buildings really achieving better energy performance? The answer is yes. With many built multi-family passive projects throughout the Northeast, there are now multiple occupied projects where we can look at actual energy performance data, sometimes over multiple years. Using Passive project data from built projects in MA and PA, we will compare post-occupancy performance and cost to similar above-code and code built projects. We will also share takeaways gleaned from applying this same comparative analysis to publicly available post-occupancy benchmarking data in Philadelphia and several case studies from Massachusetts and Vermont. Learn how passive is much more consistently hitting the range of performance we will need to decarbonize new buildings and hit state and national climate targets. Discuss simple strategies for collecting more and better data that can demonstrate whether projects are achieving superior energy savings and occupant comfort.||BE21 Sessions||5/7/2021 3:30-PM||5/7/2021 4:30-PM||Katie Bartolotta , Beverly Craig , Brendan Place ||Beverly Craig ||AIA 1.0 LU/HSWMass.

|BOS21-717||Electrification + Affordable Housing: What You Need to Know||To achieve our 2050 climate goals we must go all-electric. But how do we get there? For new construction, all-electric solutions are increasingly viable. However, all-electric solutions for existing buildings are considerably more challenging. The upfront cost to upgrade old buildings to a level that ensures efficient (and economical) performance can be prohibitive. Worse still, going all-electric without sufficiently improving envelopes can result in high operational costs for both owners and residents, jeopardizing our ability to provide and preserve truly affordable high-quality housing. Using case study examples, we will walk through the implications of electrification of multifamily affordable housing, and discuss as a group what the barriers and opportunities are associated with this shift. In this session, we will discuss the technical solutions, policy changes, and investments needed to ensure affordable housing meaningfully leads and benefits from the clean energy revolution. ||BE21 Sessions||5/7/2021 3:30-PM||5/7/2021 4:30-PM||Lauren Baumann , Emily Jones ||Emily Jones ||AIA 1.0 LU/HSWGBCI LEED BD+C, O+M 1.0 hourMass.
