Building the Next Generation Through 20 Years of Solar Decathlon: From Collegiate Prize to Multifaceted Clean Energy Workforce Program: Preprint

The U.S. Department of Energy Solar Decathlon, initiated in 2002 as a collegiate competition that challenges student teams to design and build high-performance, low-carbon buildings powered by renewables, has always been about developing students to be the next generation of buildings professionals. As we celebrate the 20th anniversary of the Solar Decathlon in 2022, this paper highlights its evolution from a singular prize to a multi-faceted platform preparing the broader buildings workforce to address the challenges of climate change. The original program challenged students to design and construct a residence. To improve the accessibility of the competition, the Design Challenge -- a 1-2 semester design-only competition-- was added to the Solar Decathlon platform. The Solar Decathlon has also scaled globally with events in Europe, the Middle East, China, Latin America and the Caribbean, Africa, and India. In 2021, the Solar Decathlon broadened its reach once again by introducing Solar Decathlon Pro, a zero-energy design practicum for professional architects and engineers. This paper utilizes participation data, surveys, alumni profiles, project submissions, and more to understand how changes to the program have expanded program reach to minority-serving institutions, environmental justice communities, and impacted the building industry's capacity to construct high performance and zero energy buildings. As one of the oldest federal government prizes, the Solar Decathlon offers a roadmap for dramatically increasing prize impact and demonstrates that it continues to push boundaries to tackle decarbonization and environmental justice.

EUI Benchmarks for Net-Zero Energy Buildings in India

In our study we present EUI benchmarks for NZEBs for six building types across residential and non-residential typologies and for India's five climate zones. This approach is similar to the simulation-based benchmarks used by the B3 program in Minnesota, the Cal-Arch methodology in California, and the US Solar Decathlon approach, which combine simulations with actual building data. Of the six building types we explore one in detail with a range of operation scenarios, specifically narrowing down the EUI benchmarks for mixed-mode building operation and for variable temperature set-points as prescribed in the National Building Code of India.The contribution of this work is to provide rigorous end-use level EUI benchmarks for six building types, and to describe a method for simulation-based EUI benchmarks for mixed-mode operation with variable setpoints to highlight the difference between the standard approach used for the five building types and the On-Site Construction Worker Housing which additionally has the mixed-mode variable setpoint approach.On-Site Construction Worker Housings are typically poorly constructed temporary structures, without adequate thermal comfort, It is critical to provide adequate thermal comfort to protect people from the warming effects of climate change, and to discover super efficient and cost-effective ways to do so.The methodology used for the On-Site Construction Worker Housing (CWH) results in an 80% acceptability according to the India Model for Adaptive Comfort in the National Building Code of India. EUIs of all six buildings are 60% lower than the minimum compliance with India's Energy Conservation Building Codes, providing benchmarks for efficiency levels. The end-use level EUI benchmarks are now provided to over 1800 Solar Decathlon India participants so that they can compare the performance of their NZEB designs.In particular, the CWH results provide an insight into the importance of the mixed-mode operation with variable temperature set-points. The results from the simulation study show that for an NZEB target, the EUI with standard thermal comfort model and without mixed operation is 58.26 kWh/m2*year, while that with the variable set-points of the adaptive model with mixed mode operation is 24.23 kWh/m2*year. This is a 58% reduction in EUI. Given that many building types including residential, and non-residential operate in mixed mode, it is important to take this work further to develop mixed-mode operation NZEB benchmarks so that the carbon intensity of these buildings could be lower than the standard thermal comfort model approach.
