Abstract Background and Aims The environmental impact of dialysis is now being largely recognized. It requires from the nephrology community to actively explore novel environmentally responsible health-care practices. Among them, conception of energy-efficient facilities may be an important prerequisite for improving the environmental impact of dialysis. The Passive House concept is an internationally recognised, performance-based energy standard in construction which so far has been rarely applied to medical facilities and never to dialysis centres. We report our experience with the first passive-house certified dialysis facility in Europe. Method The Passive House concept is a sustainable construction standard for nearly zero energy buildings (the Resolution of the European Parliament of 31/01/2008 has called for its implementation by all member states by 2021). Principles and design tools of the Passive House concept are freely available for all architects. The concept combines a particularly high level of insulation with a specific system of ventilation. Geothermal energy and energy from inside the building such as the body heat from the residents or solar heat entering the building are the main energy sources. Passive House buildings allow for heating and cooling related energy savings of up to 90% compared with typical building stock and over 75% compared with average new buildings. Results The François Berthoux Center (www.artic42.fr) is a 4 400 m2 dialysis facility operated by 40 health care agents and providing care to 135 patients. It was designed following the Passive-House standard, applied for the first time to such a medical building. Several adjustments specific to the dialysis activity were necessary. The most unexpected aspect was the importance of hemodialysis machines as an energy source. Thorough thermal evaluation showed that the heat provided by different type of hemodialysis machines was systematically superior to the energy mandatory during the coldest day of the year (>10 W/m2). In practice, the center turned out to be fully operational with no external source of heating. The downside was that the geothermal pump system was not sufficient to fully regulate temperatures during the warmest period of the year. Optimal cooling was achieved by the addition of conventional AC systems in the hemodialysis rooms. Overall, as compared to a similar center, energy savings provided by the The François Berthoux Center were substantially less than what is expected from a conventional Passive House building but were over 50%. The extra-cost of the construction was estimated to 3 to 5%. Conclusion In conclusion, the concept of eco-friendly building should extend to dialysis facilities. Application of the Passive House Standard in the context of hemodialysis requires to take into account some specificities that can impact the global environmental performance of the building. However, the net result is clearly in favor of such a construction, which is both affordable and sustainable.

A computational analysis of a metamaterial (MTM) window design is presented for the purpose of increasing the energy efficiency of buildings in seasonal or cold climates. Commercial low-emissivity windows use nanometer-scale Ag films to reflect infrared energy, while retaining most transmission of optical wavelengths for functionality. An opportunity exists to further increase efficiency through a variable emissivity implementation of Ag thin-film structures. 3-D finite-difference time-domain simulations predict nonlinear absorption of near-infrared energy, providing the means to capture a substantial portion of solar energy during cold periods. The effect of various configuration parameters is quantified, with prediction of the net sustainability advantage. MTM window glass technology can be realized as a modification to current, commercial low-emissivity windows through the application of nanomanufactured films, creating the opportunity for both new and after-market sustainable construction.

Smart Skin

Contemporary ecological buildings have no formal attributes that distinguish them from "standard" architecture. What is more - due to the requirements of the construction law regarding energy efficiency, currently designed buildings almost always are equipped with technologies or elements that could be described as "green" or "health promoting". The aim of the article is to check whether this thesis is indeed true. The subject of the analysis are facades - the element with the greatest impact on the shape of the building. The innovative functions fulfilled by these structures were analysed. The examples - depending on the function performed - were divided into groups: energy production, pollution absorption, thermal energy storage, response to environmental conditions and the use of recycled materials. Relatively common and experimental technologies were considered. One of the tasks of the article is an attempt to determine whether, in relation to the mentioned technologies, it is possible to assess their direct impact on the health of the inhabitants. Final conclusions were drawn on the basis of a comparison of the characteristic parameters and the environmental impact of smart skin façades.

Negative Environmental Impact

Organosulfur compounds show a negative environmental impact because of SOx emissions by combustion of fuel oils. As a consequence, removal of sulfur is becoming a worldwide challenge. The hydrodesulfurization (HDS) process achieves limited performances in the case of refractory S-containing aromatic compounds, such as thiophene and substituted benzothiophenes (BTs), which require highly energy-demanding conditions (high temperature and pressure conditions). Oxidative desulfurization (ODS) is considered the most promising alternative to HDS. During ODS treatment, the organosulfur compounds are oxidized to corresponding sulfoxides and sulfones, which can be successively removed by extraction with polar solvents. Different stoichiometric oxidants have been used in the ODS processes with a different degree of efficacy and environmental impact. The design and development of catalytic procedures can increase the ODS energy efficiency as well as make it more economical and environmentally acceptable. Here we describe the advances in nanostructured organometallic catalysis and biotechology applied to ODS treatment.

Winter Oilseed Rape

Agricultural management, environmentally friendly technologies, chemical, organic and bio-based substances used, as well as meteorological factors, have a significant impact on the fluctuations of soil organic carbon (SOC). The aim of this research was to analyze the effect of different biopreparations on the changes of SOC content and the winter wheat and winter oilseed rape yields by assessing the energy consumption efficiency and the environmental impacts. The experimental research was conducted from 2017 to 2019 in three different treatments, in two of which were used either a molasses and magnesium sulphate based-biopreparation (T1) or a bacteria-based biopreparation (T2), while treatment T3 was applied as a control where no biopreparations were used. The dynamics of SOC content were analyzed at two depths: 0–10 and 10–20 cm. For the analysis of energy efficiency indicators and environmental impacts, the greenhouse gas (GHG) and energy consumption conversion equivalents were used. A summary of the results showed that both types of biopreparations had a positive effect on the changes of SOC content, which was especially evident in the deeper layers at 10–20 cm depth, where, irrespective of the crop type, a more significant increase of the SOC content was observed every year of the experiment compared to the control treatment. Biopreparations had a significant effect in increasing the winter wheat and winter oilseed rape yield. The best energy efficiency ratio was observed in winter wheat (4.84) and winter oilseed rape (5.11) in treatment T1. The results of the environmental impact assessment showed that the lowest GHG emissions were recorded in the winter wheat production in treatment T1 at 108.7–149.1 kg CO2eq Mg−1, while the highest were observed in oilseed rape production in the control treatment T3 at 343.4 kg CO2eq Mg−1.
