ABC Research & Development Showcase | ABC Summit

Right now, there is a wide range of ABC-related R&D projects under way, including a group of specific technical R&D projects funded under DOE’s ABC Initiative. To give you a representative sampling of the new construction and retrofit projects supported by the ABC Initiative, these cover a section of the technical readiness continuum. These are some impressive teams and ideas, but I’ll also remind you that the universe of ABC is much larger than just this set of projects—or even the while cohort of DOE-funded ABC R&D teams.

1. 1 U.S. DEPARTMENT OF ENERGY OFFICE OF ENERGY EFFICIENCY & RENEWABLE ENERGY Dry Screen: it’s not the heat, it’s the humidity Fresh air is not always comfortable air, but it doesn’t give you COVID • It is costly to dehumidify mechanically with 100% outdoor air systems. Applied Energy paper http://tinyurl.com/covid-ventilation • Nearly 2 million commercial buildings and 56 million households rely on central AC = $26 Billion • Controlled based on air temperature setpoints • 90% reduction in use can be achieved with same thermal comfort with dehumidification Research Progress and Challenges • Building a prototype that dehumidified incoming wind driven natural ventilation 80% -> 50% • Exploring both vacuum membrane contracting solutions and liquid desiccant contactors • Challenge to standardize regeneration process Applied Energy paper showing >200% energy increase due to COVID ventilation and an opportunity of 50% energy decrease if done with natural ventilation Princeton (lead), Harvard, MIT, NREL, AILR, Transsolar First working drying liquid desiccant membrane wicking fin sorption panel inserted in window at AILR near Princeton Initial vacuum prototype testbed at Harvard NEW Miami testbed option with Transsolar + University of Miami
