“…Energy conservation was popularized during the oil crisis of the 1970's, but sometime in the mid 1990's, this conservation effort was changed for marketing purposes to energy efficiency (Moezzi & Diamond, 2005). The move made it a "purchase oriented rational practice, as contrasted with conservation, which was taken to mean the curtailment of needed energy services" (20).…”

“…Yet, and perhaps surprisingly, despite the state's commitment to energy conservation, research conducted to date on ground‐up energy use in California has been scarce owing to a lack of consistent and longitudinal access to full data sets of actual energy use by building or meter (Schiller Consulting ) . Research has primarily modeled or estimated the cost‐effectiveness of individual utility efficiency programs (the technologies) without the ground‐up evaluation (Moezzi and Diamond ). CPUC's consultants who are tasked with energy efficiency and evaluation do not archive electricity use and conservation program data over time, by address, nor have they established baselines.…”

Urban metabolism provides a framework to understand resource flows into cities and waste flows out. Its potential has been hampered by the lack of good disaggregated data. This article presents energy-use findings for the residential sector for the city of Los Angeles based on census-block-level aggregation of address-level electricity use obtained from the Los Angeles Department of Water and Power. City or county billing data by customer class over time can enable empirical tracking of energy conservation and efficiency programs by different customer classes, and matched to census information and county tax assessor data about building vintage, size, and type can provide information important for rate setting, for example, or energy conservation and efficiency program investments. We report on median electricity demand and corresponding greenhouse gas emissions and expenditures at three geographical aggregations: city council district (15 in total); neighborhood (114 in total); and census block group (2,538 in total). We find that the ratio of median annual demand between highest-and lowest-tier users is 26 at the census-block group level, but only 2.2 at the city council district level, demonstrating that spatial aggregation significantly masks the degree of variation that may be observed. We also show how such data can enable the description of energy to develop energy disclosure thresholds that reflect a city's morphology. In contrast to New York City's 50,000-square-foot reporting threshold, to capture half of Los Angeles' electricity consumption, the threshold for reporting would have to be 5,000 square feet.

“…However, efficiency behaviours do not necessarily result in net energy savings if, for example, energy efficient appliances are used more frequently than less-efficient models. This is an example of the rebound effect (Moezzi & Diamond, 2005): the often counter-productive behavioural response to the introduction of new, more efficient technologies. Ehrhardt-Martinez et al (2010) provide a more detailed breakdown by frequency and cost as shown in…”

Providing residential tenants with feedback on their energy use can be an effective intervention, promoting savings ranging from 4-12%. However, advancements in feedback design have been hindered by methodological limitations, the lack of specification of visual feedback designs, and a poor understanding of the behaviour changes that are induced by feedback. This thesis presents the design and demonstration of an Internet-of-Things-based feedback research platform, which was intended to help address these issues, and which will be made freely available for re-use and reconfiguration. Configured for a rental apartment building in Toronto, Canada, the platform was a central component of a conservation program and field study examining the efficacy of real-time social comparisons. Results showed a statistically significant effect of the conservation program with a relative year-over-year, weather-normalized savings of approximately 11%. An encouraging, but non-significant, finding of a 3.5% relative improvement with real-time social comparisons warrants future large scale studies.
