RESUMO

Facing space constraints similar to those experienced by many urban campuses, the University of California, San Francisco (UCSF) looked to innovative office workplace design to curb growing facilities expenditures. Mission Hall, a new office building primarily for desktop and clinical researchers and staff, was designed as an activity-based workplace (ABW), a type of open-space design. ABW was simultaneously being proposed as the template for future UCSF desktop research workspaces. ABWs can be less costly to construct than other designs, and their mix of shared and open workspaces is intended to improve efficiency and interaction. Evaluations of ABWs in corporate settings have yielded mixed results. Examples of ABW buildings for faculty in academic health centers (AHCs) are rare.The Mission Hall experience provided a unique opportunity to understand the impact of an ABW design on faculty satisfaction, work effectiveness, well-being, and engagement. In a 2016 survey of faculty, 1 year after occupancy, respondents reported adverse changes in all 4 areas. The most common complaints involved noise exposure and lack of visual and auditory privacy. In response to these issues, faculty reported working at home or elsewhere more frequently, making collaboration more difficult. In 2018, UCSF retrofitted the building to create some private offices and adjusted its overall program to balance private office and open workspaces in future projects.Lessons drawn from this experience can inform workplace solutions at other AHCs. Most critical are the needs to assess functional requirements of work and align design, change management, and technologies to support those requirements.

RESUMO

This simulation study is aimed to model a contemporary Proton Exchange Membrane fuel cell (PEMFC) CHP system having a 'heat and power' autonomy as well as a provision of demand-driven electrical supply to the grid. A novel nanowire-electrode PEMFC stack is adopted within this PEMFC CHP system so to effectively replace the existing natural gas fuelled durable solid oxide fuel cell (SOFC) CHP system installed at David Wilson Millennium Eco-house at University of Nottingham. The energy savings, environmental, and economic performances of the proposed PEMFC system are determined and compared to the base case (SOFC) which is operated continuously to maintain a 1.5 kWe. While to meetup the highly fluctuating and seasonal demands of heating and power like in the UK, a PEMFC is more productive and advantageous over a SOFC. The proposed PEMFC unlike to the SOFC will be able to operate and adjust its output and turn down instantly as per changing conditions of ambient temperatures and loads in terms of electricity and heat. The results of the modelling predicted that as compared to the base case scenario, this PEMFC CHP system will efficiently reduce an annual CO2 emission by 65.99% and fiscal costs by 66.74% with a viable internal rate of return as 8.93% and benefit to cost ratio as 1.02.

RESUMO

This study presents a systematic review of the literature on layout planning in healthcare facilities. The review includes 81 articles from journals, conferences, books, and other documents. Articles were classified in two groups according to their main contents including (i) concepts and guidelines and (ii) techniques and tools to assist in layout planning in healthcare facilities. Results indicate that a great variety of concepts and tools have been used to solve layout problems in healthcare. However, healthcare environments such as hospitals can be complex, limiting the ability to obtain optimal layout solutions. Influential factors may include the flows of patients, staff, materials, and information; layout planning and implementation costs; staff and patients safety and well-being; and environmental contamination, among others. The articles reviewed discussed and often proposed solutions covering one or more factors. Results helped us to propose future research directions on the subject.

RESUMO

Sustainable noncommercial bioinformatics infrastructures are a prerequisite to use and take advantage of the potential of big data analysis for research and economy. Consequently, funders, universities and institutes as well as users ask for a transparent value model for the tools and services offered. In this article, a generally applicable lightweight method is described by which bioinformatics infrastructure projects can estimate the value of tools and services offered without determining exactly the total costs of ownership. Five representative scenarios for value estimation from a rough estimation to a detailed breakdown of costs are presented. To account for the diversity in bioinformatics applications and services, the notion of service-specific 'service provision units' is introduced together with the factors influencing them and the main underlying assumptions for these 'value influencing factors'. Special attention is given on how to handle personnel costs and indirect costs such as electricity. Four examples are presented for the calculation of the value of tools and services provided by the German Network for Bioinformatics Infrastructure (de.NBI): one for tool usage, one for (Web-based) database analyses, one for consulting services and one for bioinformatics training events. Finally, from the discussed values, the costs of direct funding and the costs of payment of services by funded projects are calculated and compared.

RESUMO

BACKGROUND:: There is increasing evidence that the physical environment of neonatal intensive care units (NICUs), including single-family rooms (SFRs) versus open-bay rooms (OPBYs), has tangible effects on vulnerable patients. The objective of this study was to illustrate the financial implications of SFR versus OPBY units by synthesizing and evaluating the evidence regarding the benefits and costs of each unit from a hospital perspective. METHODS:: We assumed a hypothetical NICU with 40 beds in OPBY rooms, to be replaced with a new NICU with 32 SFRs and 8 OPBYs. We synthesized evidence regarding the comparative benefit of each option on 3 outcomes-nosocomial infections, length of stay, and direct costs. We calculated incremental benefit-cost ratio separately considering each outcome over an analysis period of 5 years. A ratio of more than 1 indicates that the investment is worthwhile. Input parameters were assigned probability distributions representing the degree of uncertainty around their true values. Monte Carlo simulation with 5000 iterations was used to quantify the distribution of benefits and costs. RESULTS:: The mean value of the incremental benefit-cost ratio was 0.730 (95% credible interval: 0.724-0.735) when nosocomial infections were considered, 1.298 (1.282-1.315) when reduced length of stay was considered, and 1.794 (1.783-1.804) when direct costs of care were compared. The probability of a benefit-cost ratio of lower than 1 was about 91%, 31%, and 2% in each case, respectively. CONCLUSION:: Cost savings associated with SFR units would justify additional construction and operation costs compared to OPBY units only when evidence on inclusive outcomes such as length of stay or direct costs of care is considered. A specific outcome such as infection rate potentially fails to capture all benefits of SFRs. As more evidence becomes available on full benefits and hazards of SFRs versus OPBYs, future studies should investigate the broader return-on-investment outcomes.

RESUMO

Green buildings have been viewed as one of the most effective solutions to the negative environmental impacts of construction activities. For the sustainable development of the economy and the environment, many governments in the world have launched a variety of policies to encourage the development of green buildings. However, green targets achieved during the operational stage of green buildings are far below the expectations from the design stage. In addition, the development of green buildings is unevenly distributed in different cities. To help resolve these issues, this paper identifies 28 green building influencing factors from two perspectives, the life cycle and stakeholders. Then, a social network analysis is used to analyse their interactions and identify the critical factors. Our results show that government supervision, incremental cost, property management experience, and the awareness of environmental protection in green buildings are the critical influencing factors in promoting green building development. However, some factors related to contractors, designers and suppliers are not as important as perceived. Finally, some policy recommendations are proposed to promote green buildings in China.

RESUMO

BACKGROUND: Climate change negatively impacts human health through heat stress and exposure to worsened air pollution, amongst other pathways. Indoor use of air conditioning can be an effective strategy to reduce heat exposure. However, increased air conditioning use increases emissions of air pollutants from power plants, in turn worsening air quality and human health impacts. We used an interdisciplinary linked model system to quantify the impacts of heat-driven adaptation through building cooling demand on air-quality-related health outcomes in a representative mid-century climate scenario. METHODS AND FINDINGS: We used a modeling system that included downscaling historical and future climate data with the Weather Research and Forecasting (WRF) model, simulating building electricity demand using the Regional Building Energy Simulation System (RBESS), simulating power sector production and emissions using MyPower, simulating ambient air quality using the Community Multiscale Air Quality (CMAQ) model, and calculating the incidence of adverse health outcomes using the Environmental Benefits Mapping and Analysis Program (BenMAP). We performed simulations for a representative present-day climate scenario and 2 representative mid-century climate scenarios, with and without exacerbated power sector emissions from adaptation in building energy use. We find that by mid-century, climate change alone can increase fine particulate matter (PM2.5) concentrations by 58.6% (2.50 µg/m3) and ozone (O3) by 14.9% (8.06 parts per billion by volume [ppbv]) for the month of July. A larger change is found when comparing the present day to the combined impact of climate change and increased building energy use, where PM2.5 increases 61.1% (2.60 µg/m3) and O3 increases 15.9% (8.64 ppbv). Therefore, 3.8% of the total increase in PM2.5 and 6.7% of the total increase in O3 is attributable to adaptive behavior (extra air conditioning use). Health impacts assessment finds that for a mid-century climate change scenario (with adaptation), annual PM2.5-related adult mortality increases by 13,547 deaths (14 concentration-response functions with mean incidence range of 1,320 to 26,481, approximately US$126 billion cost) and annual O3-related adult mortality increases by 3,514 deaths (3 functions with mean incidence range of 2,175 to 4,920, approximately US$32.5 billion cost), calculated as a 3-month summer estimate based on July modeling. Air conditioning adaptation accounts for 654 (range of 87 to 1,245) of the PM2.5-related deaths (approximately US$6 billion cost, a 4.8% increase above climate change impacts alone) and 315 (range of 198 to 438) of the O3-related deaths (approximately US$3 billion cost, an 8.7% increase above climate change impacts alone). Limitations of this study include modeling only a single month, based on 1 model-year of future climate simulations. As a result, we do not project the future, but rather describe the potential damages from interactions arising between climate, energy use, and air quality. CONCLUSIONS: This study examines the contribution of future air-pollution-related health damages that are caused by the power sector through heat-driven air conditioning adaptation in buildings. Results show that without intervention, approximately 5%-9% of exacerbated air-pollution-related mortality will be due to increases in power sector emissions from heat-driven building electricity demand. This analysis highlights the need for cleaner energy sources, energy efficiency, and energy conservation to meet our growing dependence on building cooling systems and simultaneously mitigate climate change.

RESUMO

This paper contributes to the pursuit of socially sustainable water and sanitation infrastructure for all people by discovering statistically robust relationships between Hofstede's dimensions of cross-cultural comparison and the choice of contract award types, project type, and primary revenue sources. This analysis, which represents 973 projects distributed across 24 low- and middle-income nations, uses a World Bank dataset describing high capital cost water and sewerage projects funded through private investment. The results show that cultural dimensions explain variation in the choice of contract award types, project type, and primary revenue sources. These results provide empirical evidence that strategies for water and sewerage project organization are not culturally neutral. The data show, for example, that highly individualistic contexts are more likely to select competitive contract award types and to depend on user fees to provide the primary project revenue stream post-construction. By selecting more locally appropriate ways to organize projects, project stakeholders will be better able to pursue the construction of socially sustainable water and sewerage infrastructure.

RESUMO

Large-scale airport construction removes large quantities of earth materials, resulting in serious environmental pollution and ecosystem damage. However, studies of environmental concerns caused by the materials used in airport construction are still preliminary, and those case studies on the impacts of large-scale offshore airport development are very limited. China's Dalian Offshore Airport is considered here to study the environmental value loss from 240 million m3 of materials excavations and 21 km2 of artificial island infillings. The findings show that the calculated annual environmental value loss for the development of the Dalian Offshore Airport is approximately US$7.75 million, including US$1.81 million and US$1.47 million of direct economic loss of timber resources and marine biology resources, respectively, and US$1.53 million and US$2.79 million value losses of forest and marine ecosystem services damaged caused by materials excavation and infilling, respectively. The conclusions of this study provide an important foundation to quantitatively analyse the environmental impact of the Dalian Offshore Airport's development and can be used as a reference for similar engineering and environment impact assessment programs.

RESUMO

OBJECTIVE: To know how managers of public and private companies view lactation support rooms and their implantation. METHOD: This is study is based on qualitative, exploratory, and descriptive research. Twenty managers from Greater Florianópolis participated in the research, in 2015. Data were collected by means of semi-structured/projective interviews, and subjected to content analysis associated with Atlas.ti software. RESULTS: Data analysis led to the following two categories: difficulties and facilities of establishing a lactation room, with a predominance of financial difficulties and the lack of physical space. Dialectically, the subjects also recognised the low cost involved, which facilitates establishment. CONCLUSION: Financial, cultural, and political aspects make it difficult to set up lactation rooms, but the importance of this measure was acknowledged. Although the success of breastfeeding partly depends on these support rooms, it also requires multiple actions, especially the effective participation of nurses and other health workers.

RESUMO

This paper proposes a reliable facility location design model under imperfect information with site-dependent disruptions; i.e., each facility is subject to a unique disruption probability that varies across the space. In the imperfect information contexts, customers adopt a realistic "trial-and-error" strategy to visit facilities; i.e., they visit a number of pre-assigned facilities sequentially until they arrive at the first operational facility or give up looking for the service. This proposed model aims to balance initial facility investment and expected long-term operational cost by finding the optimal facility locations. A nonlinear integer programming model is proposed to describe this problem. We apply a linearization technique to reduce the difficulty of solving the proposed model. A number of problem instances are studied to illustrate the performance of the proposed model. The results indicate that our proposed model can reveal a number of interesting insights into the facility location design with site-dependent disruptions, including the benefit of backup facilities and system robustness against variation of the loss-of-service penalty.

RESUMO

OBJECTIVES: This paper investigates empirically whether the institutional features of the contracting authority as well as the level of 'environmental' corruption in the area where the work is localised affect the efficient execution of public contracts for healthcare infrastructures. METHODS: A two-stage Data Envelopment Analysis (DEA) is carried out based on a sample of Italian public contracts for healthcare infrastructures during the period 2000-2005. First, a smoothed bootstrapped DEA estimator is used to assess the relative efficiency in the implementation of each single infrastructure contract. Second, the determinants of the efficiency scores variability are considered, paying special attention to the effect exerted by 'environmental' corruption on different types of contracting authorities. RESULTS: Our results show that the performance of the contracts for healthcare infrastructures is significantly affected by 'environmental' corruption. Furthermore, healthcare contracting authorities are, on average, less efficient and the negative effect of corruption on efficiency is greater for this type of public procurers. CONCLUSIONS: The policy recommendation coming out of the study is to rely on 'qualified' contracting authorities since not all the public bodies have the necessary expertise to carry on public contracts for healthcare infrastructures efficiently.

RESUMO

An alternative to the traditional way of designing projects is the process of target value design (TVD), which takes different departure points to start the design process. The TVD process starts with the client defining an allowable cost that needs to be met by the design and construction teams. An expected cost in the TVD process is defined through multiple interactions between multiple stakeholders who define wishes and others who define ways of achieving these wishes. Finally, a target cost is defined based on the expected profit the design and construction teams are expecting to make. TVD follows a series of continuous improvement efforts aimed at reaching the desired goals for the project and its associated target value cost. The process takes advantage of rapid cycles of suggestions, analyses, and implementation that starts with the definition of value for the client. In the traditional design process, the goal is to identify user preferences and find solutions that meet the needs of the client's expressed preferences. In the lean design process, the goal is to educate users about their values and advocate for a better facility over the long run; this way owners can help contractors and designers to identify better solutions. This article aims to inform the healthcare community about tools and techniques commonly used during the TVD process and how they can be used to educate and support project participants in developing better solutions to meet their needs now as well as in the future.
