Physics-informed hybrid modeling methodology for building infiltration

Infiltration is responsible for one-third to one-half of the space conditioning load of a typical residential home, but the modeling of infiltration for building energy modeling is either represented by over-simplified equations or dependent on over-generalized rules of thumb. This paper develops a physics-informed data-driven methodology for modeling infiltration using building-specific empirical measurements. The developed hybrid methodology combines machine-learning categorization and grey-box sub-modeling to improve the accuracy and generalization of commonly used grey-box infiltration models. The developed methodology excels at predicting infiltration by improving the ability to predict infiltration under unseen environmental conditions using machine learning algorithms with physical significance. In a case study conducted using the iUnit, a modular studio apartment experimental test facility located at the National Renewable Energy Laboratory, we use empirical airtightness measurements to fit an infiltration model using the developed methodology. We find that the developed methodology can improve the overall model accuracy by 43% and improve extrapolation by 38%, compared with the model based on the common grey-box infiltration equation. We also notice that the selected features can improve the performance of a pure machine-learning model, indicating that our methodology identifies the features with the most physical significance to infiltration modeling.

Increase of the indoor concentration of volatile organic compounds after the use of incense and scented candle in studio apartments determined using passive sampling

Burning incenses and scented candles may provide harmful chemicals. Although many studies have evaluated volatile organic chemicals emitted by their use and related health risks, extension of our understanding for guiding appropriate use under various use conditions is necessary. In this study, emission characteristics of commercial incenses and scented candles were evaluated in a laboratory chamber using real-time measurement and the time-weighted average exposure concentrations of monoaromatic compounds and monoterpenes were assessed using passive samplers while volunteers living in a studio apartment use them. After burning incense, the average levels of benzene increased from 1.4 to 100 μg m−3. The presence of a wood core in commercial incense products was the main cause of high benzene emission by burning them although the increase in benzene was also influenced by factors such as the brand of the products, the number of incense sticks burned, the duration of each burning session, and ventilation period. Electrical warming of scented candles increased the levels of monoterpenes by factors of 16–30 on average. Considering the emission characteristics found in this study, exposure to benzene and monoterpenes could be mitigated by cautious use of those products in residential areas.

Climate resilience and energy performance of future buildings in Nigeria based on RCP 4.5 and 8.5 scenarios

The predicted rise in global temperature by the Intergovernmental Panel on Climate Change IPCC appeals for a review of the methods and materials used for building construction for reduced emissions and comfort in buildings. Buildings account for the most carbon emissions in the globe. This study presents the impact of temperature change across the 36 state capitals in Nigeria, and the Federal Capital Territory, FCT, based on Representative Concentration Pathways, RCPs 4.5 for 2020 and 8.5 for 2090. A simple studio apartment with optimised alternatives for retrofits and new builds was simulated using EnergyPlus for both climate scenarios to determine the strategies for improving the energy performance of future buildings. The result of the study shows a significant increase in mean monthly outdoor temperature of about 5⁰c across the states, with potential heat stress affecting buildings in future climates. Moreover, about one-third of the locations experience a shift in climatic zones to hotter ones. The impact of this climate drift will be more severe in the Northcentral and Southwest regions of the country. The design strategies recommended to mitigate the effects of a changing climate focused on building envelope insulation, thermal mass, and solar shading. The performance of the optimised models under future scenarios accounts for up to 25% and 73% savings in cooling energy for retrofits and new builds, respectively. To protect existing buildings from the impact of future climates, developers must make massive investments in solar shading of buildings. In contrast, a combination of envelope insulation and solar shading strategies proves effective for new builds.

Determination of terpene levels after the use of essential oil diffusers in vehicles and studio apartments using passive sampling

The exposure levels of selected terpenes (limonene, α- and β-pinenes, and γ-terpinene) emitted by essential oil diffusers in vehicles and studio apartments were assessed using a passive sampling method. A previously developed passive sampler composed of an expanded polytetrafluoroethylene membrane and adsorbent (ePTFE PS) was enlarged and made wearable. Before field deployment, the sampling performance of the modified ePTFE PS for selected terpenes was compared with that of active sampling in a lab-scale 5 m3 test chamber under constant exposure conditions, supporting that passive sampling provides reasonable estimates of the time-weighted exposure concentration. Fifty volunteers were recruited and asked to wear the ePTFE PS while using an essential oil diffuser inside their own vehicle while commuting and in their studio apartment while sleeping. Terpene levels without an essential oil diffuser were very low in vehicles and 47, 3.6, 1.6, and 0.62 μg m−3 for average concentrations of limonene, α- and β-pinenes, and γ-terpinene in studio apartments, respectively, close to those reported in previous studies. The indoor concentrations of all selected terpenes in vehicles and studio apartments were elevated by the use of essential oil diffusers, especially in vehicles. The average concentration of limonene in vehicles after the use of essential oil diffusers was 11 μg m−3, which was greater than that before use by a factor of 30. Therefore, cautious usage of essential oil diffusers indoors where the volume is limited, such as a vehicle, is needed to reduce exposure to terpenes.

Designed for Home: Opportunities for Enhanced Ontological Security in Permanent Supportive Housing Apartments

To maximize the number of new dwelling units for people experiencing long–term homelessness, permanent supportive housing (PSH) developers have minimized the floor area of such units, creating very small studio apartments in purpose–built, single–site housing projects. The objective of this study was to reveal the variety of spatial organization patterns of these apartments and to assess if theoretical hallmarks of ontological security—constancy, the ability to conduct day–to–day routines, identity construction, freedom from surveillance—may be supported by design decisions. This is the first study to closely examine the interior layouts of such dwellings, despite 1,840,000 PSH apartments having been built in the past 13 years. The dataset is a representative sample of 24 PSH studio apartment floor plans. The archival plan analysis examined typological features of the apartments and the affordances and attributes related to the hallmarks of ontological security. A key finding is that overall layout is determined primarily by entry sequence decisions: constancy and freedom from surveillance may be enhanced by close attention to the layering of this space. A second key finding is that the ability to conduct day–to–day routines and construct identity may be enriched by apartment layout and storage provision. Thus, despite the size constraints of PSH apartments, designers could possibly enhance ontological security affordances through defined layout, ample storage, and a layered entry sequence. For PSH residents, achieving ontological security in their dwellings is a necessary step toward recovery from long–term homelessness.

The Archeology of a Good Ragù: Discovering Naples, My Father, and Myself by John Domini

Shuster (bio) the archeology of a good ragù: discovering naples, my father, and myself John Domini Guernica World Editions https://www.guernicaeditions.com/title/9781771835534 285 pages; Print, $17.95 Imagine a terrace above a city of antiquity, a view of a glittering bay, a Campari in hand, and across the table an engaging fellow regaling you with savvy cultural observations, tasty reminiscences, and eye-opening wartime tales. If that sounds appealing but you can't swing the airfare, fix the drink yourself and crack open a copy of The Archeology of a Good Ragù, wherein the affable jack-of-all-trades John Domini (novelist, critic, poet, journalist, translator) will tell you about Naples. Author of three novels set in this complex, melting [End Page 81] pot of a city—famous for pizza, postcard views, and Vesuvius; notorious for crime and grit—Domini now delivers a freewheeling memoir to explain how and why the place has come to mean so much to him. If you're wondering about the title, the book is not a tour of Italian cuisine (though the region's pleasures don't go unnoticed). Rather, the sauce is mostly metaphorical—a bubbling mix of lives, sights, and feelings that Domini encounters and discusses, turning up surprises and a couple of shockers. "The Neapolitan ragù," the author writes, "is always in ferment, yielding briny intrigue." Much of the book's intrigue centers around Domini's father, Enzo Vicedomini, who grew up in Naples under the Fascists and the Nazis and then fled his country in 1948, at age twenty-three, for Manhattan. He shortened his last name to a word of the church and went on to prosper in the food industry, putting an Italian spin on American standards. His success had always accounted for his eagerness to emigrate, but had there been another reason? He'd hardly ever spoken about his teenage years in the war. It was not until Domini was forty, in a mid-career malaise with a failing marriage, that he felt an urge to dig into his family's past, to make more meaningful connections to his heritage. "In order to get a handle on the rest of my life," he writes, "I needed to know my father and his city." Domini begins the account of his quest like an easygoing raconteur, less concerned with chronological sequence than with capturing what he calls the "confounding total immersion" of Naples, where "there's no end of 'now.'" Impressions stream into memories, which bring on sudden thoughts, confessions, literary references, and historical asides. Early on, a description of votive figures leads to octopus in an insalata, margherita pizza, an old photo of Domini's father, women's shoes, Margherita the queen, the suicide of the Siren Partenope, Sibyl of the Aeneid, roughnecks with facial scars, and finally back to that photo—all within a few pages. The sentences themselves keep you on your toes, too, mixing the fine-tuned perception exhibited in Domini's literary criticism (see his excellent The Sea-God's Herb [2014]) with the punchier, improvisational style of his more recent fiction. Here's one view of Naples (with "monkey" referring to an ancient Greek settlement): [End Page 82] Whenever I pull out of downtown on a ferry, headed for the monkey islands, the retreating urban landscape looks like a palimpsest: a tattered sedimentary buildup. The heights west of the docks present a stipple of ridges and colors, a slope known as Pizzofalcone, the falcon's hood. I can just see it, the bird in its hood. Or maybe not (what do I know about falcons?), and anyway this quarter too has more than one story to tell. So does the book. As the family's harrowing experiences in World War II gradually come to light, Domini brings you scenes from modern-day Naples, notably in romance, immigration, and organized crime. One afternoon he ends up in a cramped studio apartment, posing without a shirt for a woman who's painting portraits of male artists and writers. The scene reads like a...

I knew nothing about the role of this river in Tokyo’s urbanization, its usefulness in military defense, its romanticized image in popular culture, or even where it started and ended. I certainly did not think of the river as a providential source of drinking water. It just made me sad. It was, in my eyes, an eyesore, along with the exposed electric wires, gray-tiled apartment buildings, and treeless roadways that often made me wonder, “How did this ancient city of 37 million become so ugly?” Discounting my obvious symptoms of first-year Tokyo culture shock, the Kanda River near my apartment was indeed a bare concrete ditch, with steep canalized walls channeling a thin, seemingly lifeless beige stream far below street level, inaccessible to life around it.

Design of Multifunction Cabinet for Limited Space in Apartment

A cabinet is a storage that is considered effective and efficient because apart from being useful as a place to store various items, it adds aesthetic value to a space. The high demand for land for housing has led to vertical flats, like apartments. An apartment with a studio type has simply one room, where the only space with a section is in the bathroom. In this type of apartment, furniture with optimal function is needed because the space in a studio apartment is very minimal but still compact to maximize every available space. Multifunctional furniture is suitable for studio-type apartments because it has more value in both ergonomics and economics. This design creates a multifunctional cabinet with a retro theme suitable for residential needs with relatively limited space. It has various functions as a storage for cutlery needs and can transform into a dining table set equipped with folding stools for 2-4 people. The design used the four-phase Design Thinking method in the Double Diamond model, such as discover, define, develop, and deliver. The methods used in the design are qualitative and quantitative data analysis using questionnaires, documents, and literature studies.

SMART APARTMENT DESIGN FOR A LOW MOBILE RESIDENT

The article considers the problem of design of a smart apartment as a new level of historical development of small housing. Various aspects of housing cell formation are considered in the scientific works of Bachynska L.G., Gnesya I.P., Gnat G.O. etc.The history of furniture development with the signs of transformation was studied by scientists: Bosyi I.M., Mygal S.P., Z. Dyachun., Vergunova N.S. The purpose of the study is to identify methods of forming the interior of a small residential cell, taking into account the requirements of comfortable living for a small mobile resident. Factors that determine the comfort of the living cell environment and the means to create conditions to ensure a comfortable stay and life in a limited area have been identified. One of the aspects of shaping the interior design of a smart apartment is the use of furniture-transformers. The classification of furniture-transformers according to the level of transformation is carried out: furniture that changes its position without changing the function; furniture that combines several functions; spatial «housing cube».
 The main directions of architectural and planning organization of smart apartments are identified: hotel-type apartment, studio apartment, apartment with two rooms, and their possibilities for organization of main functional zones. The basic expedient architectural and planning schemes of smart apartments with examples of their zoning, placement of furniture and interior design are developed and given. It was found that to create a barrier-free living environment for a low-mobility resident, the most acceptable schemes are a two-room apartment or a studio apartment, due to the size and square shape of the plan, which allows you to organize movement and access to furniture in a wheelchair. Based on a comprehensive consideration of the requirements for environmental comfort, regulatory requirements for barrier-free space, features of the use of furniture-transformers, compositional techniques of space organization, ergonomics and energy efficiency, the use of new technologies and modern environmental finishing materials, have been developed and implemented in real design smart apartment concept for little mobile resident. The description of project development with the substantiation of the accepted decision is given. According to the results of the study, recommendations for the design of the interior of a smart apartment for a low-mobile resident were formulated, including: «free floor», access and ease of use of furniture, equipment and technical equipment; use of furniture-transformers.

Natural Ventilation Optimization Study in Mechanically Ventilated Studio Apartment Room in Surabaya

After Covid-19, residential has become the main space for every activity, including work, education, and leisure. Therefore, comfort in residential space is crucial to the occupant. As researchers have found traces, that the virus is airborne, the air quality in the residence must be highlighted, especially for people who live in a centralized cooling system residence. When the cooling system is well maintained, there is no significant risk of viral transmission, but not all residential building has HEPA-filters, nor a well-maintained system. This research focuses on the studio room apartment unit, as it has the smallest opening area compared to other room types. A small one-sided opening is not ideal for the wind to move throughout the room. A few design suggestion is simulated under three air-flow speed, to prove that natural ventilation is possible to be adapted, to reach comfort while minimizing the risk of viral transmission. The result is, the indoor wind speed can be enhanced the most at the overall unit area by modifying the fixed window to an operable window, giving upper horizontal opening in the wall across the existing opening, and using gauze doors on both door openings. The furniture layout is proved to affect wind distribution in the room. This research can also serve as an alternative strategy to optimize the use of natural ventilation to decrease energy use for cooling in the tropic area, after the pandemic. © 2021 Tamkang University.

Natural L ighting of Studio Apartment with East-Oriented Opening

Less optimized natural lighting would result in apartment residents being dependent on artificial lighting, thus increasing energy consumption. Building opening orientation considerably influences the natural light intensity. This research aimed to analyze the natural lighting pattern on apartment units with east-oriented opening orientation and determine methods to support the existing condition to be optimized. This research applied the descriptive analysis research method assumed from calculation outcome of the software DIALux. Results indicated a proportion of units in The H-Residence Apartment do not meet the requirements specified by SNI 03 6197-2011, predominantly in the kitchen area. The average light intensity in a day in units with east-oriented opening reached its peak at 08.00 – 09.00 a.m. and decreased towards 16.00 p.m. following the sun path. The light intensity in numerous areas exceeded the requirements significantly. Other factors influencing the natural light distribution are layout and interior element. Several ways to optimize the natural light intensity utilization are adding suitable shading device, using dark-colored interior elements, and considering the sun path in designing building openings.

Brushes with Cancer goes digital

“I'm alone in my studio apartment, I can't go outside. I can't see anyone. I'm really bored.” Sound familiar? This has been the norm for many over the past several months of the COVID-19 pandemic. But cancer activist and founder of not-for-profit Twist Out Cancer Jenna Benn Shersher is not describing her experience during lockdown—she is talking about what it was like to be severely immunocompromised while receiving treatment for grey-zone lymphoma in 2010. We discuss all of this on a Zoom call, one of several for both of us that day.

Secure Health Fog: A Novel Framework for Personalized Recommendations Based on Adaptive Model Tuning

The emergence of smart technology has equipped humans with wearables and sensors that collect relevant data related to individuals and their surroundings. In healthcare, the collected data can monitor user emotion, behavior, and activity, which leads to the development of personalized decisions and improves lifestyle. In this paper, we analyzed the existing health fog framework and identified its limitations in terms of security, performance, and accuracy. Based on these limitations, we propose a secure health fog (SHF) framework that collects data from different Internet of Things (IoT) devices and maintains a personalized repository for adaptive model tuning. The adaptive model improves periodically based on user feedback and generates a personalized recommendation. Moreover, the existing IoT devices mostly rely on low-cost and low-power Zigbee technology, which is vulnerable to different attacks, such as device control, eavesdropping, fake device injection, malicious insider, man-in-the-middle, masquerading, message tampering, privacy leakage, and replay attack. Therefore, we propose a Zigbee Secure Health Fog (ZigbeeSHF) protocol, which uses symmetric and public-key cryptography to prevent these attacks. For data migration security, we concatenate the encrypted data with the encrypted digital signature to provide data authenticity, integrity, and confidentiality. To support our claims, we use the automated formal verification tools Scyther and AVISPA (Automated Validation of Internet Security Protocols and Applications), which evaluate the protocols based on the threat model and exploits the vulnerabilities in different attacking environments. The results of both tools ensure prevention against the mentioned attacks. As a proof of concept, we also evaluate the accuracy and performance of our proposed framework in a smart studio apartment. The result shows that the adaptive model tuned for an individual user is very effective, and the average accuracy of 32.5% is improved after one month. Furthermore, the proposed ZigbeeSHF protocol requires 7.93% and 25.35% more computation time than Zigbee with and without installation code, respectively.

A view from the other side: A senior’s view of participating in online groups during the pandemic

ABSTRACT While Covid-19 has taken a heavy toll on the 1.3 million residents in nursing facilities, there are five times the number of elders who live in the community. This story highlights the perspectives and experiences of an active senior in an independent living facility in Toronto who transitioned to online groups during the pandemic. A positive experience in an online group, together with her own resilience and tenacity, introduced her to a whole new world of online groups, enabling her to stay healthy, active, and connected beyond the confines of her studio apartment. As the pandemic and winter leave seniors living in the community indoors for the foreseeable future, there is need to draw attention to online recreational/leisure groups and build capacity for them.

Development of an income and cost simulation model for studio apartment using probabilistic estimation

ABSTRACT The Korean construction industry has attracted interest and investment demand for lease-oriented investment products, such as shopping malls and studio apartments, as a substitute for financial products because of the low interest rates of the banks that resulted from the economic recession after the global financial crisis in 2008. However, there have been huge economic damages because of problems such as the oversupply, the increase in the unsold presale rate, and the decrease in rental profit. For studio-apartment development projects, dynamic analysis should be applied considering the correlation of variables in business analysis, which is complicated by such factors as profit structure and money flow. Therefore, we aim in this study to develop a statistical analysis model of studio apartments using probabilistic estimation. For this purpose, we developed a causal-loop diagram and established a simulation and optimization model. The developed model was verified by applying it to actual cases. Our results can be used as a reference for the optimization and risk management of studio-apartment business analysis in academia. In addition, from a practical point of view, this model can be used to develop a forecasting feasibility study based on risk and for business feasibility analysis.
