Energy Transparency in the Multifamily Housing Sector

Mirroring recent trends in other real estate sectors, the multifamily housing sector is subject to an increasing number of rules and regulations related to energy-performance benchmarking and performance disclosure. State and local governments are moving rapidly to institutionalize benchmarking and make energy performance information available in the real estate marketplace, while major lending institutions are taking initial steps to factor building energy performance into financial products. The goal of these new rules is to enable transparent building energy-performance information to drive energy efficiency improvements in multifamily housing that lower energy bills for residents; contribute to greater local housing affordability; and new jobs and services related to energy efficiency. Many multifamily owners and operators have never benchmarked the energy performance of their buildings, while other parties -- including state, local, and federal policymakers, tenants, utilities, and lenders -- have little or no access to building energy-performance information that can help shape real estate decisions or inform the development of policies, incentives, and financial vehicles to advance energy efficiency. This critical shortage of information about building energy performance has prevented property markets from valuing energy efficiency and severely undermined both public and private efforts to increase the energy efficiency of multifamily housing.While energy benchmarking and disclosure policies are an innovative approach to overcome energy-performance information gaps in the multifamily sector, several challenges must be addressed. The multifamily sector is fragmented and resists a one-size-fits-all approach, ranging from low-income public housing to luxury properties, all with varied sources of public and private financing. Policies must reflect and accommodate the diversity of both the building stock and its stakeholders. In many cases, underlying barriers continue to limit the ability of many multifamily owners to conduct benchmarking and other energy-performance assessment measures. This report is intended to serve as a guide for policymakers and multifamily stakeholders on benchmarking and disclosure rules and regulations. It provides an introduction to the multifamily housing sector, followed by a thorough review of existing benchmarking and disclosure policies and an assessment of continuing policy challenges and opportunities

Quantitative description of the fruit industry and fruit supply chains in Poland

The development of consumer-driven, efficient, responsive and innovative supply chains is crucial for the growth of fruit consumption in Europe and for a competitive, sustainable fruit sector. Currently, fruit supply chains are characterized by a relatively low level of consumer orientation and consumer-driven innovations. The awareness of the functioning of supply chains in the European fruit sector should be increased to be able to increase the level of consumer-drivenness, efficiency, and responsiveness of fruit supply chains. This paper presents the results of review of fruit supply chains’ from the fruit industry in Poland. The analysis of supply chains is preceded by a review of fruit consumption, fruit production, trade characteristic and trends. Moreover, the role of different actors in the functioning of fruit supply chains is presented as well as their quantitative characteristics. To present the characteristics of the fruit industry in Poland with particular attention to functioning of supply chains in Poland, desk research was carried out. This type of research includes use of general access sources of information. The following sources were used: literature on functioning of supply chains and role of particular actors in a chain, analyses considering characteristic of fruit industry conducted by various research institutes as well as reports on a current state and development perspectives of fruit market in Poland. In addition, statistical data from the national statistical office were used.fruit production, fruit consumption, fruit industry, fruit supply chains, trade, horticulture, Agricultural and Food Policy, Food Consumption/Nutrition/Food Safety,

Quality of life and chronic pain four years after gastrointestinal surgery

PURPOSE: Little is known about the prevalence of chronic postsurgical pain after gastrointestinal surgery. This study was designed to assess the prevalence of chronic pain and quality of life in a cohort of patients who underwent surgery for benign and malignant gastrointestinal disease. METHODS: A prospective cohort design was used to assess quality of life and morbidity at four years postoperatively in 435 patients who had upper, hepatopancreaticobiliary, small-bowel, and/or colorectal anastomotic surgery in 1999 at one regional center in Northeast Scotland. Chronic pain and quality of life were assessed by postal survey using the European Organization for Research and Treatment of Cancer Quality of Life-C30 questionnaire and McGill Pain Questionnaire. RESULTS: Of the 435 patients recruited in 1999, 135 (31 percent) had died by censor date in 2003. There was a 74 percent (n = 202) response rate from surviving patients eligible for follow-up. Prevalence of chronic pain at four years postoperatively was 18 percent (95 percent confidence interval, 13-23 percent). Pain was predominantly neuropathic in character; a subgroup reported moderate-to-severe pain. Risk factors for chronic postsurgical pain included female gender, younger age, and surgery for benign disease. Compared with those who were pain-free at follow-up, patients with chronic pain had poorer functioning, poorer global quality of life, and more severe symptoms, independent of age, gender, and cancer status. CONCLUSIONS: The prevalence of chronic pain after laparotomy for gastrointestinal malignancy and nonmalignant conditions at four years after surgery was 18 percent. These patients had significantly poorer quality of life scores independent of age, gender, and cancer status.Dr. Julie Bruce is funded by the Medical Research Council (MRC) Special Training Fellowship in Health Services & Health of the Public Research

Dynamical van der Waals atom -surface interaction

We obtained new nonrelativistic expression for the dynamical van der Waals atom -surface interaction energy of very convenient form for different applications. It is shown that classical result (Ferrell and Ritchie, 1980) holds only for a very slowly moving atom. In general case, the van der Waals atom -surface interaction energy manifests strong nonlinear dependence on velocity and distance. In close vicinity of metal and dielectric surfaces and velocities from 1 to 10 Bohr units the dynamical van der Waals potential proves to be significantly lower that in static case and goes to the static values with increasing distance and (or) decreasing velocity.Comment: 15 pages,4 figures; corrected abstract,numerical calculations and conclusion
