DOE ABC: Integrated Whole-Building Energy Efficiency Retrofit Solution for Residences in Cold/Very Cold Climates
Led by School of Architecture Professor Bess Krietemeyer, together with a multidisciplinary team of Syracuse University researchers and two start-up companies, this project was designed to develop a novel overclad panel energy-efficiency retrofit with integrated heating, cooling, ventilation and water heating for residential buildings in cold/very cold climates.
As part of the the Phase 1 ABC FOA topic Integrated Building Retrofits, this project was chosen to design and prototype a technology or approach that provides a deep energy-saving retrofit solution for a building energy systems.
After a competitive review, the team received a Phase 2 award to demonstrate faster, cheaper, less disruptive and low carbon building renovation and construction techniques in low-income communities across the US. In this phase, awardees will develop and field-validate their retrofit solution from Phase 1 on at least two occupied, operational buildings.
This project is supported by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy under its Advanced Building Construction (ABC) initiative, with additional support from NYSERDA.
The goal of the project was to develop and demonstrate prototypes for a transformative whole-building energy-efficiency retrofit solution for attached single-family homes in cold/very cold climate regions. The approach is designed to be extendable to detached single-family residences and low-rise multifamily housing and will be affordable enough for public and private building owners to implement.
The project team developed three key technical innovations to achieve this goal:
- A novel highly insulated exterior building envelope system that can be modularly attached to existing building enclosures, which includes a flashing solution for windows, doors, and penetrations for mechanical services
- An envelope-integrated HVAC solution that connects to an optimally-sized modular mechanical pod providing real-time performance monitoring to enhance indoor space conditioning and air quality
- A retrofit protocol and design-to-analysis workflow for selecting and scaling the retrofit system components for site-specific conditions
Envelope and mechanical system prototypes for the retrofit solution were developed and fabricated by project partners Cocoon Construct and tkFabricate. The prototypes were tested using Syracuse University’s Building Energy and Environmental Systems Laboratory (BEESL) and the Building Envelope Systems Test (BEST) facility, under the leadership of Professor Jianshun Zhang and Dr. Rui Zhang at Syracuse University’s College of Engineering and Computer Science. VIP Structures provided valuable industry feedback on the installation process, including time- and labor-tracking. A team of faculty and students from the School of Architecture, coordinated by Professors Bess Krietemeyer and Amber Bartosh, developed a digital component database and design protocol for the retrofit solution using low-to-middle income residences operated by the Syracuse Housing Authority as the basis of design.
For retrofits in cold/very cold climates to maximize potential energy savings, they must capture efficiencies in energy performance, installation, and ongoing operations and maintenance while delivering thermal comfort, ventilation, and indoor air quality (IAQ), design aesthetics, and competitive cost benefit to ensure market acceptance. This project addresses the critical need for innovation in integrated processes for retrofit design, analysis, fabrication, and installation to capture economies of scale, compress time and cost, and facilitate widespread applicability and adoption. The resulting approach to deep energy-efficiency retrofits will establish a replicable and scalable solution to achieving 75% or greater energy savings from space heating, space cooling, water heating, and ventilation loads. If fully adopted to multiple residential building types across the U.S., the proposed approach could lead to significant CO2 emission reduction associated with the energy generation and potential energy savings of 1,812 TBtu/year.
