ComStock Measure Documentation: Geothermal Heat Pumps + High Efficiency Envelope + LED Lighting Package

Summary

This document outlines a simulation study to evaluate the impact of energy efficiency upgrades in the U.S. commercial building stock. The approach involves modeling a comprehensive package of seven measures, including geothermal heat pumps, high-efficiency envelope improvements (windows, walls, roof), and LED lighting, applied to the ComStock model which represents the 2018 commercial building baseline. The work is in progress, with results to be published in public datasets for various stakeholders to analyze the potential for energy savings and emissions reductions.
