Physics + Architecture + Human Physiology: Elements for Sustainable Action

The modern Passive House movement has spanned 25 years, from physics experiment to building codes, and few professionals have had a front seat, leading the way, this entire time; Helmut Krapmeier is one of them. Understanding the physical laws of energy is not so difficult but harnessing that understanding in a way that works with, and supports, architectural design and our human experience, is an ongoing exploration and development of growing sophistication. Today a wide variety of human activity and architectural styles share a common bond of low energy sustainable development. From measured energy use, to life cycle costs, Helmut will show how we all, as individuals, have an important role in future progress.

New York City: A Market in Transformation

Cities and metropolitan regions are leading the way in making a low-energy sustainable future and we are fortunate that New York City is a leader of leaders. Guided by its commitment to reduce carbon emissions 80% by 2050, New York City is enacting significant initiatives to transform how New Yorkers make and operate buildings. And because most buildings that will exist in 2050 exist today, particular efforts are being made toward low-energy and Passive retrofits. From Local Law 31, to the Mayor's Carbon Challenge program, there is a concerted effort demonstrate the viability and effectiveness of innovative new build and retrofit strategies such as Passive House and encouraging the private sector to capitalize on this market shifting opportunity. Hear the strategies and specific examples - from the Mayor’s Office of Sustainability, the NYC Department of Design and Construction and the affordable housing developer, Ridgewood Bushwick Senior Citizens Council - that are transforming our market.

Big Building Ventilation: What's the Big Deal?

As Passive House building grow in size and complexity - our understanding of large-scale systems integration is critical, and none more so than the ventilation systems. From multifamily to multiuse buildings, common in New York City, there is a tremendous need to better understand the critical issues and options professionals have at their disposal today, as well as what's unresolved and needs to be tackled next. This moderated discussion of leading ventilation manufacturers and audience Q&A seeks to identify key issues and different potential approaches to addressing them.

The Economics of Passive House: From Proforma to Banked Returns

Passive House buildings, like all construction projects, must be economically viable and sensible. Yet accounting the economics of a construction project can make things less clear, depending on reference points chosen and metrics emphasized. Then throw renewables into the mix and it becomes even more tricky. Two architect/developers will share their approaches toward making economic sense of Passive House buildings: tools to better understand all the variables in play, strategies for cost effectiveness, and suggestions on how to structure the analysis for a clear and concise economic case; followed by a question and answer discussion, moderated by the editor of CRAIN'S New York Business.

Passive + Renewables: Passive House Institute on the Frontier

The Passive House Institute is the independent scientific research organization that kicked-off the modern Passive House movement, and with ever growing research efforts it continues to lead Passive House development globally. Learn about the latest research initiatives - new components, new building types, new climate conditions and a new level of renewable energy integration. As Passive House is implemented in every climate zone globally and enclosing every conceivable occupancy type, with varying power supplies - we can all better understand the implications and opportunities to making our own Passive House buildings.

Multifamily Passive House: Into the Weeds

Affordable multifamily construction has historically been a driver of Passive House buildings, and the New York and tristate region is no exception. Today, there is a quickly growing number of larger multifamily buildings in design and construction. It is critical that those working in these projects learn from each other. This presentation will look at cases studies from two leading professionals - examining critical aspects: enclosure and window selections, ventilation equipment, domestic hot water and lighting – where New York City density and Connecticut climate pose specific challenges.

Real Data from Real Buildings: Get the Download

The first question many ask is: where's the data? And not European data, but North American and local data. This presentation provides two sets of answers to that question. First, in collaboration with Con Edison, City College of New York and New York Passive House, four certified Passive House buildings located in New York and New Jersey are being monitored. Did actual energy use match the projected energy use as stated in PHPP? Did they conform with Passive House standards and met adequate indoor environmental conditions? How do they compare with current and projected New York City energy codes? Second, is a study of a multifamily building in Peterborough, Ontario and a single-family home on Wolfe Island, Ontario. A post-occupancy evaluation was completed on the buildings to establish the real performance and comfort of the buildings compared to energy simulations. Energy models were compared to collected energy bills and data loggers collected indoor environmental conditions. Find out the results and the lessons learned.

Early Learning, Primary Schools & Conference Facilities: An Education in High Performance

Education buildings are also a leading Passive House building type around the world, and as cities and institutions seek greater sustainability, Passive House is an important option. Three examples will be presented. An early childhood center in historic Brooklyn Heights, a primary school and an adult meeting and training facility. From highly variable occupancy populations, multi-use and commercial demands, to historic integration and architectural expression, see how these three teams are delivering an education in Passive House high performance.

The Commercial Facade as a High Performance System: Opaque, Curtain Wall & Reskinned

As interest grows in Passive House, commercial buildings are becoming more frequent and the solutions around facade systems are often less obvious. This session will tackle three aspects of high performance commercial facades and the Passive House standard. First, the opaque systems - the panels, the clips, the potential thermal bridging and how to make it work. Next, the curtain walls - ubiquitous in NYC - the curtain wall needs a careful and critical examination in application to Passive House buildings. Finally, NYSERDA is undertaking a bold initiative, called RetrofitNY, to potentially jump-start the systemic wrapping of large commercial multifamily buildings with the occupants remaining in place – and giving the new facade systems-wide responsibilities. See the details and strategies around these three critical façade approaches.

ASHRAE Standard 90.1 Appendix G, PHI and PHIUS+: A NYSERDA Comparative Evaluation Study

This presentation reviews the results of a study undertaken by NYSERDA to compare the predicted energy performance of several representative high performance designs of a multifamily new construction project following ASHRAE 90.1 Appendix G, the Passive House Standard and PHIUS+ modeling protocols. The modeling was performed by independent teams with expert knowledge of the protocols and associated simulation tools. Comparison of the energy use predicted through each of the three protocols, analysis of the sources of the differences such as modeling assumptions and defaults, the capabilities of simulation tools, and the metrics used to express building performance in each protocol will be shared. The study results and methodology may be used to establish equitably stringent performance thresholds for the three protocols.

Factories Go Passive: Cold & Hot-Humid Climates

Manufacturing buildings as Passive Houses? Not long ago this might have been thought a joke. But today not only are Passive House factory buildings successfully operating, new ones are popping up in unlikely places. See two new and very different examples: A health products manufacturer in cold Ontario and a garment facility in hot and humid Sri Lanka. See the strategies, details and decisions to make this new breed of Passive work.

Passive Wood Structures: EnerPHit in the City & New Upstate

Wood frame construction dominates large parts of the building market in America. It is critical, to both retrofit existing wood framed buildings to Passive standards, as well as make all new constructions Passive. This presentation takes a close look at a wood frame retrofit home example in Brooklyn as well as new affordable multifamily wood frame construction up the Hudson Valley for Habitat for Humanity. See the commonalities and differences in detailing, systems integration and energy balance optimization.

What Now? What Next?:
A Closing Panel Discussion

There is growing momentum today for Passive House performance, but can it scale like renewables are currently? To stabilize our global climate, is it fair to say that we need our building sector to go carbon negative and hence need Passive and renewables to scale together? If so, what are the next steps in making our "negative-carbon future" a reality?
