    A single dwelling archetype design subjected to be constructed in Gaziantep City to provide accommodation for the earthquake victims was researched in this paper. It is aimed to find out the optimum building orientation, window-to-wall ratio, and aspect ratio as design variables to achieve Zero Emission Building target. In this regard, the GenOpt Optimisation tool was coupled with the EnergyPlus simulation tool to run the simulations and optimise proposed design scenarios. A threshold value for primary energy use based on the EPBD recommendation document as a guide was improved to determine ZEB design scenarios. It is evident from the 56.43% primary energy use difference between the lowest and highest energy performance among design scenarios that optimum design variables are highly effective in terms of energy efficiency. Besides, 82 design scenarios achieving the ZEB threshold were elaborated from the design variables’ point of view that rectangular forms and low WWRs are optimal for the selected region. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024

    Latent heat storage for centralized heating system in a ZEB living laboratory: integration and design

    No full text
    The ZEB Lab project, coordinated by SINTEF and NTNU, aims at building a ZEB (Zero Emission Building) in Trondheim (Norway) in 2019, to be used both as office building and living laboratory. An innovative latent heat storage (LHS) unit using phase change material (PCM) will be integrated in the centralized heating system. The LHS unit will be able to store excess heat from various heat sources connected to the heating system, when they are not required for space heating. One challenge is to make use of the full potential of the PCM latent heat to have a compact and effective unit, while the unit itself should have a low associated CO2-footprint. The LHS system consists of two units designed for a total heat storage capacity of 0.6 MWh, corresponding to the heat needed on top of the heat pump to cover for up to 3 consecutive days in the coldest period of the year, with a maximum combined effect of 26 kW. A bio-based wax is used as PCM with melting temperature 37 °C and measured latent heat 198 kJ/kg. Dynamic system modelling is used to support the design of the LHS unit and ensure sufficiently high heat transfer rates.publishedVersionOpen Access.

    Reanalysis of occupant experiment in ZEB Living Lab

    No full text
    In 2015-2016, a six-month long experiment was carried out in the ZEB Living Lab, one of the first houses in Norway planned to reach net zero emission throughout its lifetime. By means of qualitative experiments, social scientists evaluated how six groups of occupants impacted the zero emission building, and how the zero emission building impacted its occupants in different ways. Data were collected through direct observation, diaries and interviews before, during and after the stay. In this paper, we take a closer look at the sensor data from the detailed monitoring system, generated during each group's 25-day long residing's. We find that despite the experiment being a controlled environment with many shared household characteristics, occupancy is determined by diverse factors, and the users' preferences and attitudes influence energy consumption. All major household appliances were the same, but the time of use, frequency, duration and type of use differed. The study contributes to increasing understanding of user behaviour and energy use in low energy houses. Providing occupancy profiles is valuable, in light of the increasing amount of local renewable energy production. These datasets can be used as input in energy simulation and planning of zero-emission neighbourhoods.publishedVersionContent from this work may be used under the terms of theCreative Commons Attribution 3.0 licence.

    Effects of Physical Activity and Exercise Interventions on Health Outcomes in Occupational Drivers: A Systematic Review

    No full text
    Background: Occupational drivers are exposed to a wide range of risk factors, including sedentary behavior and physical inactivity, which can contribute to various chronic diseases. However, exercise interventions are likely to alleviate the negative associations and reduce chronic disease risks. This systematic review aimed to inventorize research studies investigating the effects of physical activity and exercise interventions on health outcomes in occupational drivers, and to assess interventions that have demonstrated effectiveness on health outcomes in occupational drivers.Methods: The electronic databases "Web of Science," "Scopus," and "PubMed" were searched using keywords related to "occupational drivers," "exercise," and "health outcomes." Studies were included if they examined the effects of physical activity and exercise among occupational drivers on the following health outcomes: pain, disability, lifestyle factors (sleep, weight, physical activity, nutrition), fatigue, stress, and cardiometabolic risk factors. The methodological quality of the studies was assessed by the Cochrane Risk of Bias tools for randomized and non-randomized studies.Results: Fourteen articles were included (three randomized and 11 non-randomized controlled trials). All studies were judged to have an overall risk of bias as "some concerns, low, moderate or serious." Evidence suggests that stretching and isometric exercises have significantly improved pain, disability, and fatigue. In contrast, multicomponent lifestyle interventions have enhanced physical activity levels, cardiometabolic risk factors, anthropometrics (body mass index, weight, waist circumference), sleep, and dietary intake among occupational drivers.Conclusion: The available evidence indicates the potential benefits of exercise interventions and physical activity for health outcomes in occupational drivers. However, high-quality studies are needed in the future to establish stronger evidence supporting the effect of the exercise intervention.The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This research was supported by Higher Education Commission of Pakistan (HEC), Grant No. HEC/HRD/OSS-III/ Batch-3/Belgium/2022/19745

    Frequency and Antimicrobial Susceptibility Pattern of Gram-Negative Bacilli Isolated From Urine Specimens at a Tertiary Care Setting

    No full text
    OBJECTIVES: To find out the frequency and pattern of conventional antibiotic susceptibility of gram-negative bacilli cultured from urine specimens of patients at a tertiary care setting. METHODOLOGY: This study was conducted at the Microbiology Department of Combined Military Hospital Multan from June 2016 to May 2017. The data in this retrospective descriptive study was collected from urine culture records of the Microbiology Department, CMH Multan. Only those urine specimens who revealed positive gram-negative bacilli cultures were included in the study. Drug susceptibility patterns of these isolates were recorded against routinely used antibiotics (e.g. Nitrofurantoin, Imipenem, Sulbactum-cefoperazone, Gentamicin and Ciprofloxacin) and evaluated accordingly. RESULTS: A total of 1703 urine specimens were submitted for culture and antibiotics susceptibility testing during the period of study. A total of 128 specimens showed growth of gram-negative rods. Imipenem (95% sensitivity), Sulbactam- Cefoperazone (88% sensitivity) and Nitrofurantoin (87% sensitivity) were highly effective antibiotics against the cultured gram-negative bacilli in the study. CONCLUSION: This study showed that E. coli is the commonest cause of urinary tract infection (UTIs), followed by Klebsiella and Enterobacter species among gram-negative bacilli in our set up. In-vitro efficacy of Imipenem, Sulbactam- Cefoperazone and Nitrofurantoin was found to be the highest against these gram-negative bacilli as compared to other antimicrobials. On the contrary, in-vitro efficacy of ciprofloxacin and gentamycin was found to be extremely low

    THE IMPACT OF SOCIOECONOMIC STATUS ON STUDENTS' ACADEMIC ACHIEVEMENT

    Abstract: The objective of this research was to investigate how a student's socioeconomic status impacts their academic performance. A descriptive survey method was used to conduct the study on all elementary level public sector students in district Mansehra. A two-stage random sampling technique was applied to select the sample. To determine the socioeconomic status of the students, a questionnaire was designed, while a test consisting of 40 multiple-choice questions on Math and English was used to measure their academic achievement. Reliability of the instrument was measured using Cronbach's alpha, resulting in a value of 0.85 for the questionnaire and 0.83 for the test. Mean, percentage, and frequency were used for data analysis. The study concluded that students from families with average financial status performed better academically than those from below-average financial status families. Additionally, students whose parents had higher levels of education scored higher on average compared to those whose parents had lower levels of education. These findings demonstrate the importance of socioeconomic status and parental education in predicting academic success and the need for targeted interventions to address disparities in educational outcomes among students from diverse socioeconomic backgrounds.

    The net zero-energy home: Precedent and catalyst for local performance-based architecture

    No full text
    abstract: The building sector is responsible for consuming the largest proportional share of global material and energy resources. Some observers assert that buildings are the problem and the solution to climate change. It appears that in the United States a coherent national energy policy to encourage rapid building performance improvements is not imminent. In this environment, where many climate and ecological scientists believe we are running out of time to reverse the effects of anthropogenic climate change, a local grass-roots effort to create demonstration net zero-energy buildings (ZEB) appears necessary. This paper documents the process of designing a ZEB in a community with no existing documented ZEB precedent. The project will establish a framework for collecting design, performance, and financial data for use by architects, building scientists, and the community at large. This type of information may prove critical in order to foster a near-term local demand for net zero-energy buildings.Dissertation/ThesisAppendix M - Simulation and Weather DataM.S.
