Engaging the Climate Spectrum: Passive House for all

Americans perceive climate change along a diverse spectrum of beliefs beyond the binary of denial and alarm. Although connections are being forged in the public mind about the egregious effects the built environment has on climate, cultural polarization keeps us conveniently divided along political lines. As design professionals, we are primarily responsible for cultivating both an inclusive and truth-telling atmosphere on a project team so the full spectrum of climate beliefs can be explored without sacrificing the rigorous goals of low-embodied-carbon construction. But is everyone truly welcome to the table the environmentalists set? Do developers have to be eco-conscious before they can de-carbonize planet earth, or are they gracefully invited on the journey with us? 

Instead of constructing defense mechanisms against the realities of climate change, our panelists constructed climate change resilient housing. This panel will explore what they faced, why they did it, and how their lives have changed forever.

Getting to Zero through Advanced Energy Codes 

Passive House and LEED are the stars of low-carbon emissions new construction, but the humble building code has proven to be one of the most effective policy tools to advance efficiency in the broader market. Between 2006 and 2012, model energy codes had driven an efficiency improvement of 30 percent in both states and municipalities upon prompt adoption. Since then, the model codes have plateaued in the face of increasing payback periods and pushback from the building industry. Many are now wondering how to get energy codes back on track to achieve zero-carbon emissions buildings and meet climate imperatives.

Attend this session for an update on the International Code Council’s 2021 IECC development process and learn how organizations are pushing for meaningful efficiency improvements. Also, learn how states and municipalities are meeting their climate goals by developing and implementing unique energy codes, modifying the model codes, or encouraging adoption of “stretch” codes.

How Can We Leverage Public Policy to Promote Passive House and Net Zero Buildings?

Following Tim McDonald’s lead, in December 2017 Passive House Massachusetts (PHMA) began advocating for the Massachusetts Department of Housing and Community Development (DHCD) to add QAP bonus points for affordable multifamily passive house (PH) projects. That effort is ongoing, but it lead to two realizations: First, all QAPs that mention PH do not necessarily produce PH projects; Second, there several other State agencies that can be asked to promote PH buildings. These include the office of the Secretary of Energy and Environmental Affairs (EEA), Massachusetts Department of Energy Resources (DOER), Mass Clean Energy Center (MassCEC), the Energy Efficiency Advisory Council (EEAC) advising the utility companies rebate programs, and the Board of Building Regulations and Standards (BBRS).  

In addition, it became clear that PH advocacy could become more effective when combined with a host of regional groups advocating for Net Zero standards in communities across the State. The results have been impressive and should provide replicable models for other states.

Planning, Prediction, and Performance: A survey of built PHFA Passive House Projects

Learn how post-occupancy PFHA multifamily passive houses are performing compared to the pre-certified predictive models.  This session will present a cross section of passive houses that attempted hitting their model’s targets upon construction completion. Not all that made the attempt achieved that goal and their results will be included here.

Presenters will cover: 

  • Best practices that helped their projects achieve performance goals
  • Common problems that caused their projects to not meet performance goals
  • Why projects that fail to achieve the Passive House benchmarks can still be called high performance buildings
  • How well the current built Passive House projects are achieving the PHFA’s goal, which is to reduce the impact of uncontrollable utility costs

Solving the Wooden Building Puzzle - Combining Passive House + Wood Fiber + Pre-Fab

Architect, builders, and owners face multiple challenges when considering which choices will allow their construction projects to have the most significant positive impact towards combatting climate change.

  • Substantially reducing carbon emissions through building requires addressing both embodied + operational energy.
  • New challenges of health, indoor air quality, and building durability stemming from the new normal of tight building construction require a sharper focus on the design and execution of moisture management and vapor resilient assemblies.
  • Implementing good building science and ultra-low carbon assemblies can be complicated and cost prohibitive for many architects, builders, and building owners.

 

In this session, a passive house architect, builder, and fully integrated off-site manufacturing  company describe how combining repeatable passive house construction details, a multiple perspective design approach, carbon storing + vapor-open building materials, and efficient offsite manufacturing offer an affordable and predictable alternative to common passive house construction methods. Their case study of a 4800-square-foot single family Passive home describes how the resulting benefits and efficiencies of combining new cutting edge materials, integrated design strategies,  and offsite construction processes led them to further explore the potential of this collaboration. The team will share their findings on the hygrothermal performance and embodied energy of these assemblies and fabrication methods and preview how they are developing the process to include vapor-open multi-family passive housing, including factory installed MEP to further leverage efficiency in the pursuit of affordability.

The High-Performance Affordable Housing Design MANUAL

One of the most significant challenges the design and construction industries face in the next 12 years is normalizing the design of net-zero energy (NZE) housing for everyday developers, architects, engineers, and builders. Simplified, demystified, and comprehensive straight-forward strategies for approaching any-sized NZE multifamily building will be necessary in order to effectively and quickly train industry professionals. While there is an ever-increasing array of products and systems currently flooding the sustainable building market, how does one begin to ask the right questions? 

Informed by 20 years of designing multi-family high-performance buildings and more recently, five years of working on multifamily Affordable Passive House projects, this lecture is designed to provide design, development, and building professionals with a step-by-step guide to cost-effective strategies for approaching multi-family, Affordable Passive House buildings.

This MANUAL is delivered in the form of a "decision tree" with pros and cons associated with the two or three most cost-effective and energy efficient strategies for managing all aspects of designing a multi-family Passive House building, including metering, monitoring, heating, cooling, ventilation, hot water, site-built and prefabricated envelopes, foundations, and airtightness. Integrated Project Delivery (IPD) provides a strategic backbone to the MANUAL and is demonstrated through several case study projects.

The Regenerative Design Imperative

The effects of climate change have been coming faster and stronger than scientists predicted.  

Passive House is not enough! Can we extend the building-as-a-system logic of Passive House into other sectors or do these systemic solutions already exist in other schools of thought?  Holistic, regenerative community design is that mindset, and is fundamental to a living future.

Buildings should be crafted to be resilient, regenerative, and fit seamlessly into the life of the community and the natural world.We seem to believe we can use the same building forms and just use less energy. In fact, the problem is more fundamental.  The “forms” of contemporary buildings and communities have evolved around systemic dependence on massive inputs of fossil fuels. Much will have to change to achieve a future in which humans meet their needs without destroying the potential of future generations to do the same.

The ultimate manifestation of regenerative design would be communities that reverse climate change and foster localized regenerative systems, networks and economies.  Luckily for us, past civilizations have more than a few blueprints for how to create vibrant, resilient, regenerative, and community-centered places. Cohousing, pocket neighborhoods, and live/work downtowns are traditional forms that encourage interaction and engagement. This scale community typically has ample opportunity for systems of self-reliance such as localized agriculture, cottage industries, self-governance, responsive markets, and biophilic environments.  

Chris Fuller and Michael Hindle will present general principles of regenerative design and show examples of several projects of various scales that seek to realize these goals.

The Story of the New Hughson Street Baptist Church with Affordable Housing: How we got to Passive House

This session will discuss Passive House lessons learned for a growing downtown Baptist church in the planning phases for a new building who decided to go Passive House and add affordable housing to the mix. Starting with the initial conversations through design and construction of this 60,000 square-foot mixed use building in an urban setting, the presentation will share how the project got from an idea to reality. In 2016, Hughson Street Baptist Church partnered with Indwell, a leading developer of affordable housing in Ontario who had recently committed to Passive House. Leading the design team is Invizij Architects, one of Canada’s leading Passive House designers, with clients ranging from non-profits to institutional projects. This workshop is ideal for builders, developers, civic institutions, and others interested in building mixed use low-carbon buildings.

The Tricky Business of Financing Solar on Affordable Housing

Climate action requires a steep reduction in greenhouse gas (GHG) emissions and utilizing all tools in the clean energy toolbox. If affordable housing projects are to reach net zero energy usage and contribute to GHG emission reductions in meaningful ways, viable financing options to incorporate renewable energy systems into projects are critical. Multifamily buildings have great real estate for rooftop solar, yet solar installations are especially difficult to finance on affordable housing. Over the past five years, the National Housing Trust (NHT) and its partners have become experts in deploying different financing options to get solar installed on affordable housing. NHT’s portfolio financing model aligns solar incentives for property owners, investors, and lenders. This session elaborates on how to think through the different financing options available for solar on affordable housing, how to evaluate the best option for a project, and shares an affordable housing solar installation success story.

Using Smart Technology to Deliver Energy Retrofits for Multifamily Buildings 

In the City of Philadelphia, there are 425 buildings considered as “income qualified” housing (NHPD). Utilities are a significant factor for the building owners, residents, and federal assistance programs that contribute to these buildings’ expenses.

In November 2017, BlocPower, a New York-based company that uses data to make buildings greener, healthier, and smarter, completed an ECM feasibility study for four income-qualified multifamily properties in Philadelphia. BlocPower’s study recommended installing smart thermostats with indoor sensors (x15) and providing Resident training. The Pilot Scope included smart thermostat installations in four properties owned by Mission First Housing Group and Friends’ Rehabilitation Program. 

Panelists will review the scope of the pilot and review the following questions: 

  • What are the opportunities and challenges associated with the intersection of human behavior and smart devices?
  • What is the role of internet-connected networks in smart device development?
  • How can energy conservation organizations partner with utilities for pilot programs?

The Vertical Urban Village: Crosstown Concourse

Originally constructed in 1927, the Sears Distribution Center in Memphis’ Crosstown neighborhood grew into a major economic engine for the city; however, by 1983 the building sat abandoned, indicative of the modern trend of disposability and urban disinvestment. By the turn of the 21st century, this massive, deteriorating building was considered too expensive to demolish, let alone renovate. Unwilling to accept these limitations, the founders of Crosstown Arts envisioned the building as a home for their small start-up organization, with plans to organically revive the structure. With local backing and federal Historic Tax Credits, the project evolved into a “vertical urban village” blending retail, restaurants, fitness, health, education, arts, and professional spaces with market-rate and subsidized housing to create a new, equity-focused community paradigm meeting rigorous sustainability and energy use goals. Crosstown Concourse has been the recipient of more than 15 national and international awards since its opening in August 2017, including the Grand Prize from the Congress for the New Urbanism,  the AIA Honor Award for Architecture, and the designation as the largest historic adaptive-reuse LEED Platinum project in the world.
