As part of a whole-building design approach, building enclosure is a key lever in reducing operational carbon emissions. With early phase detailing, precise thermal modeling can be performed to set achievable envelope performance criteria and define critical design components. This leads to more rigorous conversations with construction partners and more certain cost outcomes. We will explore recent thermal studies of panelized enclosure solutions for large scale high rise buildings that meet Passive House performance criteria.

This session will present a case study of the 544,000 sf Harvard Science and Engineering Complex, one of the most sustainable and resilient buildings ever constructed. The project employed a highly integrated design process to satisfy the aggressive performance goals set by Harvard. These included resiliency measures to address climate change, in particular sea level rise, and the highest possible energy efficiency, while providing a healthy environment for occupants, extensive water use reduction, and recycling.

What does it take to meet the Passive House standard in countries with extreme climates? Can Passive House be adapted to specific cultural demands that seem at odds with Passive House principles? What can we learn from vernacular architecture? The session takes a deeper dive into the investigation of how the Passive House approach can be deployed globally, its opportunities and challenges.

This session will showcase the implementation of a high-performance façade assembly on an existing high rise concrete multi-family housing building complex, and the resulting measured data of operational energy and water consumption. In addition to addressing climate resilience, we will discuss how the project addresses community resilience by allowing the tenants to remain in their homes through construction and improving the quality of their spaces through design.

The impact of building materials on human and environmental health has received increased attention, and hundreds of design firms have pledged to support healthier materials. Ensuring healthier material selections requires complex decisions and collaborations. Acknowledging this challenge, how can the industry adopt meaningful material health goals across all projects? How can we build on the work others are doing?

As the energy and carbon landscape evolves, the design and construction of hospitals must change to meet new challenges. New techniques, perspectives and methodologies must be applied to drive innovation and achieve outstanding results. From the dual perspective of a CPHC and experienced HVAC design engineer, we will provide an overview of Passive House principles in the context of hospital design and construction. We will review three case studies: one occupied, one in construction, and one in design.

Think you know effective heat pump sizing and design? Significant market growth of cold-climate air-source heat pumps has resulted in new insights and lessons learned. Come explore new tools and best practices to enable improved design, sizing, and selection of ASHPs in this session with NEEP and Abode, and stay on the leading edge!

Many classroom environments are unhealthy and uncomfortable, creating poor learning environments with high absenteeism. Older, unventilated classrooms can be economically decarbonized with improved air quality and comfort. This session will present the conversion of a junior high school classroom, featuring a "rolling" room-by-room installation process using a community's local HVAC installation labor with one day of classroom downtime.

Windows are a key part of the building enclosure, but they are also the costliest, most fragile, and worst thermally performing component. We will present on windows from our viewpoint as building enclosure consultants and forensic failure specialists. We will explore energy and comfort impacts of glazing and glazing ratios, and then move on to water control detailing and the window-to-wall interface. Covered topics will include sill pan and rough opening flashings, “innie” vs.

Have you heard about the building standard that's not a standard? Learn how to create energy efficient, healthy, sustainable homes with an emphasis on making the concepts and technical details accessible to builders and designers of all levels of development. Two of the four co-authors of the Pretty Good House Book will go through the essential elements of what makes a Pretty Good House and share how it can help make low-carbon energy efficiency more accessible to contractors, designers, and clients.

Recent technology developments and incentive programs are creating new opportunities for ground-source heat pumps (GSHPs) at the building and neighborhood scale (networked geothermal). Practitioners designing and piloting GSHPs will describe how GSHPs can reduce the environmental burden on LMI communities by decarbonizing space and water heating.  Through design and case studies, they will describe what characteristics make a building or neighborhood a promising fit for GSHP implementation, and those posing significant challenges.

We will present tales from the trenches for ventilation approaches within the context of the Passive House building certification standard. This standard has set a high benchmark for low-energy buildings and is widely known as the most rigorous energy efficiency standard currently available. Attendees will learn how balanced ventilation is best applied in a cold climate at a large scale and how commissioning plays a key role in this process.

Public school projects are a highly visible commitment from a community towards future generations, serve a wide range of students from diverse backgrounds, and are a valuable resource to the surrounding community. This case study will show three projects that aimed to fit within the goals and budget of a public institution while focusing equally on energy, carbon, water, and waste. Linking the strategies for each goal to impacts on the health and well-being of students provides a new framework for evaluating the impacts of design.
