Determining Utility System Value of Demand Flexibility From Grid-interactive Efficient Buildings

This report focuses on ways current methods and practices that establish the value to electric utility systems of distributed energy resource (DER) investments can be enhanced to determine the value of demand flexibility in grid-interactive efficient buildings that can provide grid services. The report introduces key valuation concepts that are applicable to demand flexibility that these buildings can provide and links to other documents that describe these concepts and their implementation in more detail.The scope of this report is limited to the valuation of economic benefits to the utility system. These are the foundational values on which other benefits (and costs) can be built. Establishing the economic value to the grid of demand flexibility provides the information needed to design programs, market rules, and rates that align the economic interest of utility customers with building owners and occupants. By nature, DERs directly impact customers and provide societal benefits external to the utility system. Jurisdictions can use utility system benefits and costs as the foundation of their economic analysis but align their primary cost-effectiveness metric with all applicable policy objectives, which may include customer and societal (non-utility system) impacts.This report suggests enhancements to current methods and practices that state and local policymakers, public utility commissions, state energy offices, utilities, state utility consumer representatives, and other stakeholders might support. These enhancements can improve the consistency and robustness of economic valuation of demand flexibility for grid services. The report concludes with a discussion of considerations for prioritizing implementation of these improvements

Canadian / U.S. Exchange Rates and Nonresident Investors: Their Influence on Residential Property Values

Factors external to a home’s characteristics may influence the sales price. This analysis focuses on Bellingham, Washington, because of several influences including the Canadian economy and nonresidents. First estimated is a constant-quality Bellingham housing price index, which is used as the dependent variable in a reduced-form model of market price to estimate the impact of the exchange rate. The analysis (1984-94) suggests that a 10% rise in the exchange rate leads to a 7.7% rise in Bellingham home prices. Additionally, in 1990, non-county buyers paid 4% to 6% more than county residents and non-county sellers received 6% to 8% less.

Environmental Determinants of Housing Prices: The Impact of Flood Zone Status

This study examines the valuation of homes located within 100-year flood plains. Utilizing a database of 29,887 property transactions in Alachua County, Florida, the results of this investigation suggest that comparable characteristic homes located within a flood zone sell, on average, for less than homes located outside flood zones. Interestingly, the price differential is less than the present value of future flood insurance premiums. In addition, the price differential is shown to have increased since passage of the National Flood Insurance Reform Act of 1994. Finally, it appears that property tax assessors have slightly over-assessed properties located in flood zones relative to those in other areas. The large database and the lengthy period of analysis (1980–1997) are much broader than that of previous research efforts.

Factors Affecting Residential Property Development Patterns

The pattern of residential development within the context of metropolitan growth and development has been the subject of an extensive literature. Among the streams of literature have been monocentric and policentric models, rent gradients and population density, and spatial mismatch and jobs/housing balance. Less explored have been the factors determining the specific location of development from within a larger set of suitable locations. This paper uses a disaggregated data set, county property appraiser data, to track the number of new single-family housing units built in each section (square mile) of Alachua County, Florida by the year built over a twenty- year period. The paper explores the role of transportation, large-scale development, employment nodes, existing patterns of development, and regulation on the spatial pattern of development. As discussions turn to smart growth, compact development, and the alleviation of sprawl, it is important to understand the forces that contribute to observed development patterns.

Cost of saving natural gas through efficiency programs funded by utility customers: 2012–2017

This study estimates the cost of saving a therm of natural gas from energy efficiency programs funded by utility customers during the period 2012 to 2017. Berkeley Lab researchers compiled and analyzed efficiency program data reported by investor-owned utilities and other program administrators in a dozen states representative of the four U.S. Census regions — Arkansas, California, Connecticut, Iowa, Massachusetts, Michigan, Minnesota, New Jersey, New York, Oklahoma, Rhode Island and Utah. Depending on the year, the dataset accounts for about 50 percent to 70 percent of annual national spending on natural gas efficiency programs. The estimated cost of saving natural gas during the study period is $0.40 per therm. The analysis also includes estimates of the program administrator cost of saved energy for three core sectors for natural gas: commercial and industrial, residential, and low-income households. It aggregates these sectors to provide regional and national values. Our metrics include savings-weighted averages, unweighted medians, and interquartile ranges (25th and 75th percentiles) of the levelized program administrator cost of saving gas, in constant 2017 dollars. In addition, the study analyzes cost trends during the study period, finding that average program costs trended downward. The U.S. Department of Energy’s Building Technologies Office supported this work

Older Adults and Forgoing Cancer Screening

Although there is a growing recognition that older adults and those with extensive comorbid conditions undergo cancer screening too frequently, there is little information about patients’ perceptions regarding cessation of cancer screening. Information on older adults’ views of screening cessation would be helpful both for clinicians and for those designing interventions to reduce overscreening

Cost of Saving Electricity Through Efficiency Programs Funded by Customers of Publicly Owned Utilities: 2012–2017

This report finds that energy efficiency programs for customers of publicly owned utilities saved electricity at an average cost of 2.4 cents per kilowatt-hour (kWh) from 2012 to 2017. Utilities use such cost performance metrics to assess effectiveness of efficiency program portfolios, determine what programs to offer customers, and, more broadly, ensure electricity system reliability at the most affordable cost as part of electric utility resource adequacy planning and resource procurement processes. The study analyzed efficiency program data reported by 111 program administrators for 219 publicly owned utilities in 14 states — about 90 percent of the municipal utilities and public utility districts that report the data to the Energy Information Administration (EIA). The data represent 88 percent of all spending and 75 percent of all savings that publicly owned utilities reported to EIA in those years. Berkeley Lab used data from several sources, including data provided directly by American Public Power Association members, publicly available annual reports and regional data collections

Pheromone-Dependent Destruction of the Tec1 Transcription Factor Is Required for MAP Kinase Signaling Specificity in Yeast

AbstractThe yeast MAPK pathways required for mating versus filamentous growth share multiple components yet specify distinct programs. The mating-specific MAPK, Fus3, prevents crosstalk between the two pathways by unknown mechanisms. Here we show that pheromone signaling induces Fus3-dependent degradation of Tec1, the transcription factor specific to the filamentation pathway. Degradation requires Fus3 kinase activity and a MAPK phosphorylation site in Tec1 at threonine 273. Fus3 associates with Tec1 in unstimulated cells, and active Fus3 phosphorylates Tec1 on T273 in vitro. Destruction of Tec1 requires the F box protein Dia2 (Digs-into-agar-2), and Cdc53, the Cullin of SCF (Skp1-Cdc53-F box) ubiquitin ligases. Notably, mutation of the phosphoacceptor site in Tec1, deletion of FUS3, or deletion of DIA2 results in a loss of signaling specificity such that pheromone pathway signaling erroneously activates filamentation pathway gene expression and invasive growth. Signal-induced destruction of a transcription factor for a competing pathway provides a mechanism for signaling specificity

Sleep Medicine Care Under One Roof: A Proposed Model for Integrating Dentistry and Medicine

Integrating oral appliance therapy into the delivery of care for sleeprelated breathing disorders has been a challenge for dental and medical professionals alike. We review the difficulties that have been faced and propose a multidisciplinary care delivery model that integrates dental sleep medicine and sleep medicine under the same roof with educational and research components. The model promises to offer distinct advantages to improved patient care, continuity of treatment, and the central coordination of clinical and insurance-related benefits
