SEMINAR: Decarbonizing Residential Space Heating and Cooling in California – Energy, Emissions and Costs

Seminar Abstract 

Shuba Raghavan proposes a bottom-up model that potentially can lend itself easily to develop scenarios to decarbonize space conditioning in buildings. Based on the model,  the talk will present results for decarbonizing residential heating and cooling demand in California under current climate and under climate change.  Energy, emissions and costs of heating and cooling with technologies and fuel types that are prevalent in residential buildings will be compared with high efficiency electric heat pump space conditioners (HPSC)  that can both heat and cool. Market-ready HPSC is found to be more economical than the existing paradigm of heating and cooling with two different appliances, under certain conditions. Further, future energy demand for heating and cooling are projected with population growth and increased air conditioning saturation under climate change, for each of California’s sixteen climate zones. Finally, trajectories are developed for the residential sector to meet the states’ goal of 80% reduction in emissions by 2050 relative to 1990.

Shuba V. Raghavan
Researcher, Energy & Resources Group, U.C. Berkeley

Shuba Raghavan is a researcher at the Energy & Resources Group at U.C. Berkeley. She is interested in the assessment of renewable energy technologies and policies to promote a low carbon economy. Her current research involves evaluating life cycle costs and emissions of technologies and modeling pathways to reduce greenhouse gas emissions, especially from buildings sector in California. Earlier, she has worked on the techno-economics analysis of decentralized solar applications and evaluated policies to address energy equity in India. Prior to that, she worked as a Senior Research Associate at Yale University’s Investments Office, where she developed analytical models for endowment and pension fund management. She holds a PhD in Mathematics from University of Pittsburgh.
