The construction industry in New England is witnessing a significant shift toward high-performance building methods, and at the center of this transformation is the SIGA High-Performance Construction Academy in New Hampshire. In a detailed interview with Ken Kiefer, the Academy Director at SIGA North America, the vision and purpose behind this specialized training facility come into sharp focus. The academy aims to bridge the gap between conventional construction practices and the rigorous demands of Passive House standards. Understanding the building science behind a showcase home high performance construction is essential for grasping why such training facilities are critical to the future of the industry.
The Mission Behind SIGA and Its Commitment to Passive House
SIGA is a privately owned Swiss company driven by a mission that its two founders hold close to their hearts: a world of zero energy loss buildings. This vision aligns naturally with the Passive House movement, which prioritizes extreme energy efficiency through meticulous design and construction. Ken Kiefer, who serves as both the manufacturers’ representative and the director of the High-Performance Construction Academy, explains that maintaining an airtight building envelope is one of the most critical components of achieving zero energy loss.
Unlike many product manufacturers that simply sell materials and leave builders to figure out the details, SIGA takes a different approach. When builders work with SIGA products, they receive support at every stage, from product selection through installation and final verification. This philosophy extends beyond mere product development into genuine partnership. The company actively seeks alignment with like-minded organizations that share its commitment to improving the building industry, not only from an energy savings perspective but also from a building durability standpoint. This comprehensive approach to construction quality is echoed in the development of high performance concrete materials mix design properties and applications for superior construction, where material science meets real-world durability requirements.
Inside the High-Performance Construction Academy Facility
The SIGA High-Performance Construction Academy is located in New Hampshire, approximately 30 minutes north of Boston. Despite the “New Hampshire” label that might suggest a remote location, the facility is remarkably accessible to professionals throughout the Greater Boston area and beyond. This strategic location was chosen deliberately to serve a dense population of architects, builders, engineers, and construction professionals working across New England.
The region is seeing growing interest in high-performance housing, as highlighted by reports of new communities embracing these standards. Recent developments such as the New England high performance housing communities demonstrate the increasing demand for well-trained professionals who can deliver on the technical requirements of energy-efficient construction. The Academy positions itself as a direct response to this demand, providing accessible training to anyone involved in the building process.
The training curriculum is structured into two distinct phases. The first phase focuses on building science theory, covering the “how” and “why” behind high-performance construction. Students engage with experiential experiments that demonstrate the value of airtightness and the thermal capacity of building envelopes. Once the theoretical foundation is established, the training moves into physical practice using a pair of seven-foot mock-up cubes. This combination of classroom knowledge and hands-on application ensures that participants leave with both understanding and practical skill.
Hands-On Training Through Experiential Learning Methods
The centerpiece of the Academy training experience is the pair of seven-foot mock-up cubes. These full-scale models allow trainees to practice applying air barrier membranes, sealing penetrations, and installing tapes in a controlled, low-pressure environment. Participants range from experienced builders and architects to engineers, consultants, realtors, and even homeowners who want a deeper understanding of what constitutes a high-performance building.
The mock-up cubes replicate real-world conditions that builders will encounter on actual job sites. Trainees learn how to handle transitions, corners, and penetrations points where air leakage most commonly occurs. By working through these details on the cubes, participants develop muscle memory and problem-solving skills that translate directly to field performance. This tactile, hands-on methodology is central to the SIGA training philosophy. The approach aligns with research into advanced wall assemblies high performance residential construction design systems integration, where proper installation techniques are critical to achieving the intended thermal and air-sealing performance.
The curriculum is adapted from SIGA’s global training program, originally developed at its headquarters in Ruswil, Switzerland. Zack Semke of Passive House Accelerator, who experienced the Swiss training firsthand before the International Passive House Conference in Munich in 2018, attests to the power of this approach. The North American version retains the same foundational components while adapting construction practices to suit American building methods. A similar facility in Vancouver, British Columbia serves Canadian markets with the same core curriculum tailored to local construction norms.
Building Envelope Science and Workforce Development
At the heart of every high-performance building lies the building envelope — the physical separator between the conditioned interior and the external environment. The Academy places heavy emphasis on understanding how air barriers, vapor control layers, and thermal insulation work together as an integrated system. Proper building envelope design is not optional in Passive House construction; it is the foundational requirement upon which all other performance metrics depend.
Ken Kiefer emphasizes that high-performance construction is not wildly different from conventional building methods, but the differences that do exist are critical. Small deviations in installation technique can lead to significant performance failures. A single improperly sealed penetration can compromise the entire air barrier, leading to energy loss, moisture damage, and reduced occupant comfort. This is why access to quality training is so essential. Builders who understand the principles behind building envelope design principles are far better equipped to deliver projects that meet Passive House standards.
Ken notes that training is fundamental to the success of high-performance projects. When projects succeed, they elevate the entire industry by demonstrating that a skilled workforce exists and that high-performance construction is achievable at scale. This creates a virtuous cycle: successful projects inspire more builders to pursue training, which leads to more successful projects, which pushes the industry forward. The Academy aims to make high-performance construction feel accessible rather than intimidating, showing builders that these goals are within reach.
Partnerships and Community Engagement at the Academy
The Academy serves as more than just a training center for SIGA products. It functions as a community resource for the entire high-performance building industry in New England. SIGA is actively developing partnerships with complementary companies in the building industry, including insulation manufacturers like Rockwool and ventilation specialists like Zehnder. These cooperative partners can use the Academy facility free of charge to host their own training sessions, creating a hub of shared knowledge and cross-disciplinary learning.
Beyond industry partnerships, the Academy is engaging with educational institutions. Discussions are underway with design schools, construction schools, and trade schools to bring students to the facility for hands-on learning events. This pipeline from education to profession ensures that the next generation of architects and builders enters the workforce with practical experience in high-performance techniques. The Academy also hosts networking events such as BS and Beer sessions and Home Builders Association gatherings, fostering a community of practice around better building methods.
Public events are held at least once per month, and private events can be arranged for companies wanting to train groups of seven to eight employees on their own schedule. Registration information is available through the SIGA website, where a training header displays the calendar of upcoming events. Word of mouth from past participants has proven to be one of the most effective channels for spreading awareness about the Academy and its offerings.
Why Training Investment Matters for Construction Quality
Ken Kiefer makes a compelling case for why builders should invest time in training despite the pressures of busy schedules. He acknowledges that taking four hours out of a day to attend a training session can seem like a significant commitment, especially given the current demands of the construction industry. However, he argues that those four hours can save dozens, if not hundreds, of hours in rework later on. The cost of fixing a failed air barrier or remediating moisture damage far exceeds the time investment required to get the installation right the first time.
Building codes are becoming more stringent across the United States, and builders who stay ahead of these changes through quality training position themselves competitively. The Academy offers its training as a free service to the construction community, removing financial barriers to entry. Understanding material performance at a deeper level helps builders make informed decisions about which products and techniques to use. This is particularly relevant when considering high strength versus high performance concrete differences, where terminology can be confusing but the practical implications are significant for building durability.
Ken emphasizes that the Academy is not about telling builders they have been doing things wrong. Rather, it is about helping them stay at the forefront of an evolving understanding of building science and construction quality. Builders often lack access to this level of training, yet it is precisely this kind of hands-on, focused learning that makes the difference between average construction and exceptional performance.
