Coprophagia is a common and undesirable behavior observed in dogs; however, little is known about its causes or possible consequences when analysis of the animal’s feces is needed for experimental purposes. Therefore, this study evaluated the effect of coprophagy on digestibility, fecal pH, and fermentative metabolites. Twelve healthy dogs with a mean age of 3.50 ± 1.45 years were included and divided into two groups: coprophagic (COP) and non-coprophagic (NCOP). The study lasted 30 days, the last 6 days being used to collect feces for the analysis of the apparent digestibility of coefficients (ADC), fecal pH, and the concentration of short- and branched-chain fatty acids, ammonia, and fecal lactic acid. Statistical analysis was performed using the SAS software. No differences were observed for most variables, except for the ADC of nitrogen-free extract (NFE), which presented the highest average for the COP. This result should be interpreted with caution, as the NFE is estimated from calculations and was not determined in the laboratory; in addition, the results represent not only starch and sugars but also some parts referring to fibers. Therefore, coprophagy seemed not to influence the fecal variables analyzed.

Published: December 2022

Complete ammonia oxidizers (comammox) can completely oxidize ammonia to nitrate, and the various habitats of comammox Nitrospira are an important guarantee for their survival. The construction of the Three Gorges Dam, China, made it easier for nitrogen to stay in the reservoir area, which may have caused the niche differentiation of comammox, thereby affecting the natural transformation process of nitrogen in the reservoir area. This study investigated comammox in river sediments in the Three Gorges Reservoir area. Comammox clade A and comammox clade B were detected in all samples, and comammox clade A was dominant. The number of dominant OTUs (Operational Taxonomic Unit) in comammox clade A.1 accounted for 18.69% of the total number of OTUs, followed by comammox clade A.2 (18.58%) and clade B (14.30%). The indicated abundance of comammox Nitrospira clade A and clade B amoA genes in the main stream of the Three Gorges Reservoir increased along the length of the river and reached the maximum in the middle part of the reservoir area. The highest abundance of ammonia-oxidizing archaea (AOA) amoA genes appeared in the upper stream section of the reservoir area. Comammox Nitrospira clade A exhibited the highest abundance (3.00 × 104 ± 8782.37 copies/g), followed by comammox Nitrospira clade B (1.83 × 103 ± 1019.82 copies/g), ammonia-oxidizing bacteria (AOB) (1.28 × 103 ± 574.69 copies/g), and AOA (1.73 × 102 ± 48.05 copies/g). The abundances of both comammox clades A and B were positively correlated with sediment pH, indicating that pH is an important environmental factor affecting the growth of comammox bacteria. Additionally, the relative abundances of both comammox clade A.2 and clade B were significantly correlated with overlying water dissolved oxygen (DO) in the reservoir area. This study thus indicated that there exists a niche differentiation of comammox Nitrospira in the main stream of the Three Gorges Reservoir area. The potential changes in the ammoxidation process and the environmental effects caused by this niche differentiation need further attention.
Influence of Water Depth and Slope on Roughness—Experiments and Roughness Approach for Rain-on-Grid Modeling
Authors: Hinsberger Rebecca , Biehler Andreas , Yörük Alpaslan
Published: December 2022

Two-dimensional (2D) models have become a well-established tool for channel flow, as well as rain-induced overland flow simulations. In channel flow simulations, slopes are usually less than a few percent and water depths are over several meters, while overland flow simulations show steep slopes and flow of a few centimeters. Despite these discrepancies, modelers transfer roughness coefficients, validated for channel flow, to overland flow. One purpose of this study is to verify whether roughness values from the literature are also valid for overland flow simulations. Laboratory experiments with different degrees of bed roughness, various discharges and a range of experimental flume slopes were carried out. For a given discharge, water depth was measured, and bed roughness was derived. Experimental results reveal that roughness shows no clear dependence on slope but is strongly dependent on water depth for vegetated surfaces. To verify the influence of different roughness approaches, they were implemented in a 2D model. A comparison of different simulation results indicates differences in the hydrograph. Here, consideration of water depth-related roughness coefficients leads to retention and translation effects. With the results of this study, modelers may enhance the precision of the hydraulic component in overland flow simulations.

Published: December 2022

Groundwater is the single source of water in El-Dakhla Oasis, western desert, Egypt. The main objective of this study is an assessment of groundwater in the area for agriculture and drinking compared to Egyptian and World Health Organization criteria. Most the contamination of water in the study area comes from human and agricultural activities. Thirty soil profiles were studied in the area and we assessed soil quality. Seventy-four samples were taken from the area’s groundwater wells to assess the chemical characteristics of the groundwater. Moreover, the contamination of groundwater by farming and anthropogenic activities was assessed using a land use/land cover (LULC) map. Nine standard water criteria were determined to assess groundwater quality for agriculture. Furthermore, the resulting risk to human health and agricultural crops has been addressed. Therefore, the drinking quality of groundwater samples is graded as low as the hydrochemical study showed high TH, EC, TDS, Ca2+, Mg2+, Mn2+, and Fe2+ contents of 40.5%, 2.7%, 1.4%, 3.8%, 1.6%, 86.5%, and 100%, respectively. Human health is risked by drinking this water, which negatively affects hair, skin, and eyes, with greatest exposure to enteric pathogens. Using these criteria, the majority of groundwater samples cause harmful effects on soil types and are toxic to sensitive crops (vegetable crops). In conclusion, the output of this research is a map showing groundwater suitable for consumption and agriculture in El-Dakhla Oasis based on all indices using the Geographic Information Systems (GIS) model. Additionally, there was evidence of a linear relationship between soil quality and irrigation water quality (R2 = 0.90). This emphasis on tracking changes in soil/water quality was brought on by agricultural practices and environmental variables.

Published: December 2022

This study investigates the potential of Sentinel-1 data in assisting flood modeling procedures. Two different synthetic aperture radar (SAR) processing methodologies, one simplified based on single-flood image thresholding and one automatic based on SAR statistical temporal analysis, were exploited to delineate the flooding caused by a storm event that took place in Spercheios River, Central Greece. The storm event was simulated by coupling a HEC-HMS hydrologic model and an integrated 1D/2D HEC-RAS hydraulic model. Both SAR methodologies were compared to each other and also used as a reference to test the sensitivity of the hydraulic model in the variation of upstream discharge and roughness coefficient. Model sensitivity was investigated with respect to the change in the derived inundation extent and three additional metrics: the Critical Success Index (CSI), the Hit Rate (HR), and the False Alarm Ratio (FAR). The model response was found to be affected in the following order: by the upstream inflow, and by the variation of the roughness coefficient in the main channel and in the land use “cultivated crops”. The discrepancies observed between model- and SAR-derived inundation products are associated with the uncertainty accompanying the SAR processing and the utilized satellite data itself, the underlying topography, and the structural uncertainty inherent in the modeling procedure. Regarding the SAR methodologies tested, the second one (FLOMPY approach) proved to be more suitable, yielding a more coherent and realistic flooded area. According to the applied metrics and considering as reference the FLOMPY result, model performance ranged between 22–27.5% (CSI), 36.9–60.4% (HR), and 62.1–68.2% (FAR).
Comparing CSM-CROPGRO and APSIM-OzCot Simulations for Cotton Production and Eddy Covariance-Based Evapotranspiration in Mississippi
Authors: Chatterjee Amitava , Anapalli Saseendran S.
Published: December 2022

Optimizing irrigation water use efficiency (WUE) is critical to reduce the dependency of irrigated cotton (Gossypium spp.) production on depleting aquifers. Cropping system models can integrate and synthesize data collected through experiments in the past and simulate management changes for enhancing WUE in agriculture. This study evaluated the simulation of cotton growth and evapotranspiration (ET) in a grower’s field using the CSM-CROPGRO-cotton module within the Decision Support System for Agrotechnology Transfer (DSSAT) and APSIM (Agricultural Production Systems simulator)-OzCot during 2017–2018 growing seasons. Crop ET was quantified using the eddy covariance (EC) method. Data collected in 2017 was used in calibrating the models and in 2018 validating. Over two cropping seasons, the simulated seedling emergence, flowering, and maturity dates were varied less than a week from measured for both models. Simulated leaf area index (LAI) varied from measured with the relative root mean squared errors (RRMSE) ranging between 20.6% to 38.7%. Daily ET deviated from EC estimates with root mean square errors (RMSEs) of 1.90 mm and 2.03 mm (RRMSEs of 63.1% and 54.8%) for the DSSAT and 1.95 mm and 2.17 mm (RRMSEs of 64.7% and 58.8%) for APSIM, during 2017 and 2018, respectively. Model performance varied with growing seasons, indicating improving ET simulation processes and long-term calibrations and validations are necessary for adapting the models for decision support in optimizing WUE in cotton cropping systems.
Coagulation and Flocculation Optimization Process Applied to the Sidestream of an Urban Wastewater Treatment Plant
Authors: Barros Arturo , Vecino Xanel , Reig Mònica , Cortina José Luis
Published: December 2022

Ammonium (NH4+) recirculation from the streams generated in the dehydration stage of the sludge generated in the anaerobic digestion of urban wastewater treatment plants (WWTPs), known as centrate or sidestream, produces a reduction in the efficiency of WWTPs. Given this scenario and the formulation that a WWTP should be considered a by-product generating facility (biofactory), solutions for ammonia/ammonium recovery are being promoted. These include a nitrogen source that reduces the need for ammonia production through the Haber–Bosch process. Therefore, the recovery of nutrients from urban cycles is a potential and promising line of research. In the case of nitrogen, this has been aimed at recovering NH4+ to produce high-quality fertilizers through membrane or ion exchange processes. However, these techniques usually require a pretreatment, which could include an ultrafiltration stage, to eliminate suspended solids and organic matter. In this case, the coagulation/flocculation (C/F) process is an economical alternative for this purpose. In this work, the sidestream from Vilanova i la Geltrú WWTP (Barcelona, Spain) was characterized to optimize a C/F process before being treated by other processes for ammonium recovery. The optimization was performed considering a bibliographic and experimental analysis of several operating parameters: coagulant and flocculant agents, mixing velocity, and operation time, among others. Then, the removal efficiency of control parameters such as turbidity, chemical oxygen demand (COD), and total suspended solids (TSS) was calculated. This optimization resulted in the use of 25 mg/L of ferric chloride (FeCl3) combined with 25 mg/L of a flocculant composed of silicon (SiO2 3%), aluminum (Al2SO4 64.5%), and iron salts (Fe2O3 32.5%), into a 1 min rapid mixing process at 200 rpm and a slow mixing for 30 min at 30 rpm, followed by a final 30 min settling process. The numerical and statistical results of the process optimization reached 91.5%, 59.1%, and 95.2% removal efficiency for turbidity, COD, and TSS, respectively. These efficiencies theoretically support the enhanced coagulation/flocculation process as a pretreatment for a higher NH4+ recovery rate, achieving 570.6 mgNH4+/L, and a reduction in the dimensioning or substitution of other membrane processes process due to its high TSS removal value.
Factors affecting patient decisions to undergo testing for cancer symptoms: an exploratory qualitative study in Australian general practice
Authors: Venning Brent , Bergin Rebecca , Pearce Alison , Lee Alex , Emery Jon D.
Published: December 2022

Background

Patients presenting to their GP are often concerned their symptoms may be due to cancer. However, there is a lack of evidence on the factors that influence patient decisions to undergo investigation for suspected cancer in the general practice setting.

Aim

To identify the factors influencing patient decisions to undertake investigations for suspected cancer in general practice.

Design & setting

An exploratory qualitative, semi-structured interview study of patients attending rural and metropolitan general practices in Victoria, Australia.

Method

A purposive sample of 15 general practice patients aged ≥40 years participated. Thematic analysis of transcripts drew on interpretative description methodology and shared decision-making (SDM) theory.

Results

Cancer-related concerns such as ‘cancer worry’ prompt patients to seek investigations from their GP. Participants prefer that their symptoms are investigated regardless of cancer risk. The perceived ‘best test’ provides the most reassurance. Trust and SDM enhance dialogue between patients and GPs about diagnostic testing strategies. Deterrents to testing included out-of-pocket costs, waiting time, travel time, and competing work and family demands.

Conclusion

There may be a mismatch between efforts to rationalise investigation use and patient preferences for investigation. SDM that incorporates patient concerns, facilitators, and barriers to testing may ensure appropriate and timely investigation of cancer symptoms.

Triple elimination examination plays an important role in overcoming the transmission of HIV (Human Immunodeficiency Virus), syphilis and hepatitis B in pregnant women to their babies. Factors that influence mothers to perform triple elimination checks include attitudes, husband's support and distance to health services. The purpose of the study was to determine the effect of attitude, husband's support and distance to health services on triple elimination examinations for pregnant women At UPTD of Palla Public Health Center, Wewewa Utara District, Southwest Sumba Regency. The research design used correlation analytic approach cross sectional. The research population was 120 pregnant women and the research sample was 30 respondents with the determination using purposive sampling. The data collection technique used an instrument in the form of a questionnaire sheet. The data analysis method used is the Spearman Rank test. The results showed that most of the 17 (56.7%) respondents had a poor category attitude about the triple elimination examination, most of the 18 (60.0%) respondents received support from their husbands in the lower category, and most of the 21 (70.0%) respondents traveled long distances. to health services in the very far category and almost all 23 (76.7%) respondents did not perform a triple elimination examination. The results of the Spearman Rank prove that the factors that influence the triple elimination examination in pregnant women are attitude (p = 0.000), husband's support (p = 0.000) and distance to health services (p = 0.002). The next researcher needs to know other factors that influence the triple elimination examination, including maternal knowledge and socio-cultural knowledge.

Published: December 2022

Aim. To study the role of fibroblast growth factor 23 (FGF-23) as a predictor of left atrial appendage (LAA) thrombosis

in patients (pts) with non-valvular atrial fibrillation (AF) and different risk levels of thromboembolic complications (TEC) according to the CHA2DS2-VASc score.

Methods. The study included 250 pts with non-valvular AF hospitalized for radiofrequency ablation, divided into 2 groups: group (gr.) 1 - with 0-1 points (n=79) and gr.2 - with ≥2 points on the CHA2DS2-VASc scale (n=171). According to the results of transesophageal echocardiography, pts of each group were divided into subgroups depending on the presence of LAA thrombosis, which was found in 19 pts of gr.1 and 72 of gr.2. Patients underwent transthoracic echocardiography, determination of blood biomarkers: NT-proBNP (pg/ml), GDF-15 (pg/ml), FGF-23 (pmol/l), highly sensitive C-reactive protein (mg/l), cystatin C (mg/l).

Results. Pts with LAA thrombosis in both groups had in common: a longer history of arterial hypertension, a greater proportion of coronary artery disease and persistent AF, lower GFR, higher values of atrial volume indices, left ventricle myocardial mass, systolic pressure in the pulmonary artery, median NT-proBNP, FGF-23 and GDF-15. Logistic regression analysis performed separately in the groups revealed the same independent predictors of LAA thrombosis in both groups: LA volume index (LAVI) and the level of FGF-23 in the blood. At the same time, the threshold value of FGF-23, separating pts by the presence of LAA thrombosis, was higher in gr.1 (≥0.85 and ≥0.5 pmol/l, respectively), and the area under the AUC curve for FGF-23 in gr.1 was greater: 0.964 vs 0.865 in gr.2 (p=0.026).

Conclusion. The serum level of FGF-23, along with the LAVI, is an independent predictor of LAA thrombosis in pts with AF and various risk of TEC according to CHA2DS2-VASc; the threshold level of FGF-23 for pts at low risk of TEC is significantly higher than for high risk pts, and allows more accurate prediction of the presence of LAA thrombosis.

Authors: Prokopenko A. V. , Ivanitskiy E. A.
Published: December 2022

The article provides a review of international clinical studies on the use of a subcutaneous implantable cardioverter-defibrillator (ICD) in comparison with classical intravenous defibrillation systems. Subcutaneous ICDs have shown themselves to be a worthy alternative to intravenous defibrillating systems for the primary prevention of sudden cardiac death, when the patient is not indicated for anti-tachy stimulation and anti-brady stimulation. World experience on the use of subcutaneous ICDs proves the safety and effectiveness of the functioning of the subcutaneous ICD system, excluding from the patient’s life the formidable risks associated with the implantation procedure and further functioning of the classical intravenous ICD system.

PULP: Research and Experimentation in BiodegradableThin Shell Structures
Authors:   Ryerson University, Davidson Stephanie
Published: December 2022

This presentation documents in-progress design research in temporary, biodegradable structures. The experimental, thin-shell monocoque structures have been cast using a variety of cellulose-based materials, and represent a sampling of the outcome of a studio taught at three different architecture schools. The work and the process of making the work serves as an example of how designers can take responsibility for both where the materials that they choose come from, and also, where they end up. Made of exclusively recycled paper and fabric pulp, the structures have the capacity to biodegrade completely. The idea for the experimental structures came from witnessing the dumpsters overflowing with models and scrap material at the end of each semester. The conviction underlying the work is that mindful handling of resources should begin in architectural education if it is going to successfully make its way further into the discipline, profession and construction industry.Beyond handling the materials directly, students gained insight into the microstructures of the materials through the tools and knowledge offered by Peter Bush, material scientist and director of the microscopy lab at the State University of New York at Buffalo. The design task shows students how materials are responsive and constantly changing; they are not static, fixed objects. Paper is a particularly ephemeral material, highly vulnerable to moisture. Designing something with an intentionally short lifespan, and witnessing how it can break down and decay, introduces students to the transformative nature of materials, and shows how degradation and eventual decay could be a design strength. The projects are unique in that they expose students to an entire lifecycle of a full-scale spatial project, from conception through fabrication and finally, decay and complete disintegration. The process of decay and disintegration is studied with the same rigor and emphasis as the fabrication methods, through cast swatches. Because the work – both process and final, full-scale structures – is completely biodegradable, the studio avoids the creation of needless waste.

This paper illustrates how a graduate design studio can seek out an innovative and comprehensive design process, while simultaneously addressing two current crises in the architectural profession: 1) A perceived disconnect between the abstraction of design education and the realities of practice; and, 2) The critically time-sensitive imperative of transforming ecological practices in building materials and building energy consumption.
Low-Carbon Concrete Construction: The Past, Present, and Future of Concrete Design in India
Authors:   Massachusetts Institute of Technology, Ismail Mohamed A. , Mueller Caitlin T. ,   Massachusetts Institute of Technology
Published: December 2022

The concrete frame gave freedom to the design of the interior and eliminated the need for external load-bearing walls. Today, due to rapid urbanization and constrained urban space, the concrete frame has become the ubiquitous system of construction in growing cities. As a result, steel-reinforced concrete frames dominate the skylines of Less Economically Developed Countries (LEDCs) like India. Consequently, the mounting use of concrete in India has garnered concern for the ecological impacts of construction. This suggests an opportunity to reduce the carbon emissions associated with concrete construction through efficient concrete construction, building more with less. Importantly, India has a rich history of efficient concrete architecture that utilized material efficiency when material costs constrained the cost of construction. These designers cultivated a spirit of structural expression and a command of physical forces that informed a new architectural idiom for Modern India. Today, the generally risk-averse nature of development has pushed concrete construction towards standardized typologies of monolithic construction and repeated modules for ease of construction. From a structural mechanics point of view, though, these modular systems of prismatic slabs, beams, and columns, are mate- rially inefficient. In response to the demand for materially efficient concrete construction, this paper looks back at the work of novel designers in India and presents a potential application of their ideas to future urban construction in both India and beyond. The scope of this paper is the use of reinforced concrete as a structural material from the early 20th century up until today. Several key structures and designers will be highlighted for their contributions to concrete architecture’s history before concluding with a proposal for the future of concrete design in LEDC cities. Applying an understanding of concrete mechanics and digital structural design, this research explores structural systems suited to the constraints of Indian construction.
Incremental Development Manual: The Ger Innovation Hub, Mongolia
Authors:   Associate Professor, The University of Hong Kong, Bolchover Joshua
Published: December 2022

The traditional Mongolian dwelling or ger has evolved in direct correlation to the demands of nomadic life. However, its mobility, affordability and reproducibility have contributed to a rapid urbanization process in the city of Ulaanbaatar, resulting in the creation of sprawling districts with no basic infrastructure that house over 70% of the city’s population.1 During the cold winters, each household uses coal as their main heating source contributing to toxic atmospheric pollution. The lack of water and sanitation infrastructure is coupled with a lack of community provision in the form of kindergartens, schools and play spaces. As the ger districts gradually transform into more permanent forms of settlement, they are beset with ever-increasing sets of problems that have no easy fix. The implementation of large-scale infrastructure and housing development is unfeasible due to the extent of the settlements and the fact that the majority of residents own their land.2 The aim of the project is to create an Incremental Development Manual as a strategic framework for sustainable and affordable district upgrading. This paper will report o n o one component of t his M anual, T he G er Innovation Hub, a prototype for a community centre that demonstrates a methodology to engage the climate crisis through the intersection between research, design practice, and education. The process includes fieldwork, household surveys, environmental modelling, community workshops, student design-build courses, event programming, financial planning, and in-use performance testing. The paper will explain how the project innovated with passive environmental strategies to provide a low-cost solution to reduce energy consumption and the reliance on coal as a heating source. Operational since January 2020, the article will report on the effectiveness of the prototype in terms of its environmental performance and its capacity to become a model for community provision that can be replicated across other ger district areas.
From Carbon to Human Health: Lifecycle of Fossil Fuels, Toxic Polymers and Social Justice in Philadelphia
Authors:   University of Pennsylvania, Trubiano Franca
Published: December 2022

The ubiquitous use of plastics in architectural design and construction obfuscates the very real human health risks which exist when polymers—derived from petroleum, coal, or natural gas—are used in the building industry. For more than fifty years, a majority of construction materials have been engineered using polymers for the purposes of achieving a range of advanced performance capacities. These materials are widely manipulated using fossil fuel derivatives for augmenting their structural strength, moisture resistance, form finding, or general resistance to weathering. Polyvinyl chlorides, for example, are used in plumbing supplies, exterior sheathing, interior surfaces, furniture, and landscaping, for these reasons. Indeed, nearly everything in our built environment is permeated by chemicals derived from fossil fuels. This is obviously problematic for carbon emissions: it is all the more critical in what concerns human health. More than half a century following the deliberate and orchestrated flooding of the construction market with inexpensive plastics, very little data is disclosed about the potential health risks associated with adopting such large quantities of nonrenewable, nonrecyclable, and wasteful materials. Architects, engineers, builders, clients, and the general public are poorly informed on the toxic accumulation of highly synthetic building polymers that originate in carbon-intensive fossil fuel industries and that saturate our air, water, and physical bodies. In response, this paper reports on the results of a funded research project aimed at identifying the sources, risks, and impacts of using such materials in the building industry. Funded by the Kleinman Center and the Penn Undergraduate Research Mentoring program at the University of Pennsylvania, the project studies site-specific material flows involved in the lifecycle of a set of polymers manufactured in the Philadelphia region. Invisible to most, yet present in many communities, are industrial sites which distill, manufacture, and fabricate the polymerized materials that pose the highest risks when building. This has been the case in the city of Philadelphia where for decades fossil fuels and their derivatives intended for the building industry have been manipulated, with risk. Sharing evidence of this, is the focus of this paper.
Designing for Irradiated Shade
Authors:   Research Director, POST-Project for Operative Spatial Technologies Texas Tech University, Mueller Stephen
Published: December 2022

Irradiated Shade is an ongoing project that develops a means of uncovering, representing, and designing for the unseen dangers of ultraviolet radiation within conditions of apparent shade—a growing yet under-explored threat to cities, buildings, and bodies. The project leverages its position in the US-Mexico borderlands, a vital testing ground in which physiological effects of solar radiation are rendered upon vulnerable populations. This paper will discuss: the design context, considerations for ultraviolet (UV) radiation as a complex design problem, the limits of existing design tools to address conditions of UV at a building scale, and the development of custom architectural design tools to improve the ability to visualize and combat UV exposure. The paper introduces an algorithmic drawing technique capable of mapping the built environment from the perspective of UVB scatter, producing spherically-projected sky dome maps indicating the risk of UVB exposure in a particular location to sensitize designers to this hidden danger.

The built environment is responsible for nearly 40% of global energy use, significantly contributing to carbon emissions. Targeting a carbon-negative future would require a rethinking of the way we heat and cool buildings, distancing ourselves from the predominant model for the building envelope as a boundary that excludes the weather and instead adopting alternatives that transform the building envelope to a mediator that actively regulates heat exchange. In this paper, we explore the potential for a building boundary that actively heats and cools a building by forming dynamic relationships with surroundings. Most decarbonizing efforts today focus on realizing net-zero operational carbon either via the production and distribution of renewable energy or via passive house strategies that target the reduction of the active energy demand. We propose a third alternative. Instead of an endothermic model for heating and cooling in which energy is brought in the interior, transformed by a mechanical system and then distributed, we propose an ectothermic envelope system that dynamically forms a relationship with its environment, by choosing to absorb or release heat directly from or to the environment. From a design perspective, we will show a modular building energy system, comprised of a double hydronic heating and cooling layer. In essence, we are developing for a building, the equivalent to a vascular system that can move liquids at different locations to thermo-regulate. We will show how this vascular system can use ambient heat as heating and cooling sources for a building. From a more technical perspective, since all simulation tools available today assume an endothermic approach, we will show an alternative using Modelica and co-simulation for simulating an ectothermic approach. We are developing a weather chamber, which can generate an artificial version of the weather from data to test how our system would dynamically respond.

Published: December 2022

This paper discusses design research that utilized an existing project development phase to test a methodology for involving multiple projections of climate change in the design a of a present-day institutional building. In the paper an initial argument is laid out for the need for this type of design method. This is followed by a brief explanation of the methodology borrowed from charrette scenario planning and climate impact assessment. A schematic design that is the result of this planning process is then displayed as a jumping-off point to discuss design decision-making under the auspices of an unknown future climate system and the need for site-climate calibration in passive architecture. This design is the composite of three possible “optimal” buildings that represent one program designed for using climate scenarios from three major socioeconomic carbon emissions pathways. The final design is the resultant interpretation of these three futures and the needs they impose on the program and the building as a formal bioclimatic object. Concluding remarks follow the presentation of the design and decision-making theory behind its elements.
