Опыт зарубежных исследований в области акустических архитектурных решений в школах для детей с аутизмом

Nowadays, teaching children with autism in secondary schools is a new practice for Russia. Its implementation requires special knowledge and skills from all involved specialists. It also requires special architectural and design practices at all construction stages: from the project to the object itself. After competent planning decisions, the most important element is acoustic comfort in speech therapy and other rooms for inclusive purposes. Students with special educational needs, including autism, have a high level of sensitivity to noise with strong tonal, impulsive, or intermittent characteristics. A correct controlled acoustic environment is necessary to preserve the normotypic behavior of students with autism in the schools. Indeed, we should consider their needs when performing functional zoning and avoid artificial formation of a quiet environment for the learning process. Hence, generalising communication skills in an acoustically unchanged environment will ensure maximum students’ integration into social interactions both inside and outside the school.

Design and Build of Air Conditioners with Peltier Modules and PID Controls

Air conditioners are among the technologies that have been increasingly common, as time has gone on, from personal comfort to room comfort. A multi-story building is one location that requires air conditioning. This is because the structure's air pressure will rise until a certain level, making the temperature too low, so air conditioning is necessary to maintain a comfortable temperature. Similarly, in tropical areas where the temperature exceeds what is reasonably comfortable. However, the current air conditioner technology has the potential to harm the environment. Since Freon, which is used in it, can pass through the ozone layer. Eventually, global warming will happen and the world will get hotter. The SHT21 sensor is the kind of sensor that will be utilized in this final project since it has strong and steady chemical resistance over time and uses the I2C interface. This type of sensor is also capable of being utilized as a calibrated ambient temperature sensor, with a digital output form already comprised. This sensor will enable us to create a PID system with feedback that monitors the temperature produced by the Peltier module along with reacting to controlled PID by delivering PWM into the driver, then subsequently transmits the signal to the Peltier module for monitoring. When the duty cycle is 100 percent or the PWM value is set to 255, the Peltier module generates a 12-volt voltage at its best. When duty cycle 0 percent or PWM value 0 is selected, the module stops functioning. It is anticipated that this system will advance toward a Freon-free air conditioning system.

Adjustable PV Slats for Energy Efficiency and Comfort Improvement of a Radiantly Cooled Office Room in Tropical Climate

This paper investigated an application of adjustable photovoltaic (PV) slats to improve the thermal performance of an exposed glazing window and sequentially enhance the energy efficiency and thermal comfort of an office room. Solar radiation and longwave heat gains from a window fitted with PV slats were measured through experiments conducted in an outdoor chamber cooled by a radiant ceiling system. The daylight level at the workplane was also measured inside the chamber. A transient thermal model was developed and validated against experimental data. Using the experimental chamber as a demonstration case, the model revealed that adjusting the slats monthly to fully block direct sunlight could reduce the electrical energy use by 67% compared to a typical office with heat reflective glass windows. However, the electricity generated by the PV slats contributed a minor portion of the overall energy savings. To assess the thermal comfort impact of the PV slats in the room with the radiant cooling, this study utilized radiation asymmetry criteria from ASHRAE Standard 55. Simulations showed that the PV slat-shaded glazing window resulted in a lower asymmetric plane radiant temperature than the unshaded window of heat reflective glass. The adjustable slat system reduced the risk of local discomfort for occupants working near the window in the radiantly cooled office room.

Comprehensive energy demand and usage data for building automation

Buildings are essential in satisfying our daily need for comfort (privacy, protection from weather, etc.) and are responsible for almost half of the world’s total energy consumption. Research at the interface of room comfort and energy efficiency is of critical societal importance. At the same time, there is a lack of publicly available data to optimize important building functions automatically. It is only through data-driven approaches that building automation becomes financially affordable and achieves widespread adoption. In this publication, measurement data from three buildings of the NEST platform are made publicly available. The dataset includes detailed information on energy consumption (electricity, heating, cooling, domestic hot water), building operation (set points, valve openings, windows), and occupant practice (e.g., presence, operation of blinds and kitchen, showering patterns). All data have been measured over four years and with a temporal resolution of 1 minute. This combination of information allows learning the function of different building types (office and residential) and thus addresses important research gaps.

Simulation-Based Evaluation of the Impact of an Electrochromic Glazing on the Energy Use and Indoor Comfort of an Office Room

Electrochromic glazing alters its optical properties in the absence/presence of an electrical charge, varying from clear to dark to control daylighting and solar heat gains. This study aims to evaluate the impact of an electrochromic glazing, with indoor glare or temperature control, on the energy performance and thermal and visual comfort of an office room under three European climates, using a calibrated simulation model. The novelty of the paper lies in its combined performance assessment, using different standards and metrics. The results showed reduced climatization energy requirements with temperature control, but significantly increased artificial lighting energy use. Glare control achieved useful illuminance levels during 74–80% of working hours. Concerning temperature control, working hours within thermal comfort increased (21–43%) under a free-float regime. Moreover, the performance of this glazing was compared to that of a clear glazing with/without a reflective film and a thermochromic glazing for different solar orientations. The electrochromic glazing with glare control showed the highest energy savings (14–36%) for a western orientation, and the lowest negative impact on daylighting for a northern orientation. The best glare reduction was achieved with the reflective film. Considering the free-float regime, the electrochromic glazing, with temperature control, showed the highest increase in working hours within thermal comfort (6–9%) for a western orientation.

Investigation of flow generated by the collision of two opposed ceiling-attached jets from radial vortex diffusers

Thermal comfort in rooms with mixing air distribution systems is greatly influenced by air jets issuing from ceiling diffusers. Jets are often attached to ceilings, and as the attached jets collide with each other and generate flow, here called a merged jet, directed vertically and towards the occupied zone. In this research, air velocity and turbulence intensity were measured in the zone of the attached jets from two adjacent vortex ceiling diffusers and in the zone of the merged jet under isothermal conditions using omnidirectional anemometers. The jet characteristics, uniformity, similarity zone, spread rate, the position of virtual origin, centerline and profile distribution for velocity and turbulence intensity, were investigated in the ceiling-attached jet and the merged jet. The aim is to understand better the interactions between air jets created by diffusers and provide tools to designers of air distribution systems to estimate thermal comfort in the zone of the merged jet. Moreover, the results can be used to verify numerical models (CFD) and improve the reproduction of airflow characteristics created by diffusers. Velocity and turbulence intensity profiles show the presence of the similarity zone extending to the occupied zone, which is encouraging in terms of using well-known decay and profile equations to approximate velocity distribution, which has been done here. The draught rate index (DR) distribution in the merged jet was calculated from the measurement data. However, there is no known simple model to estimate turbulence intensity, which has a significant impact on the DR in the jet zone.

Data were analyzed using descriptive quantitative methods to assess the comfort level of the hospital lobby. From the results of this research, it is concluded that the aspect of freedom of movement has the greatest influence on the comfort level of the lobby space, so it must be taken into consideration when designing a hospital lobby that is comfortable for visitors.

Impact of Diffuser Location on Thermal Comfort Inside a Hospital Isolation Room

Thermal comfort is increasingly recognized as vital in healthcare facilities, where patients spend 80–90% of their time indoors. Sensing, controlling, and predicting indoor air quality should be monitored for thermal comfort. This study examines the effects of ventilation design on thermal comfort in hospital rooms, proposing four distinct ventilation configurations, each with three airflow rates of 9, 12, and 15 Air Changes per Hour (ACH). The study conducted various ventilation simulation scenarios for a hospital room. The objective is to determine the effect of airflow and the diffuser location distribution on thermal comfort. The Reynolds-Averaged Navier–Stokes (RANS) equations, along with the k–ε turbulence model, were used as the underlying mathematical representation for the airflow. The boundary conditions for the simulations were derived from the ventilation standards set by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) and insights from previous studies. Thermal comfort and temperature distribution were assessed using indices like Predicted Percentage Dissatisfaction (PPD), Predicted Mean Vote (PMV), and Air Diffusion Performance Index (ADPI). Although most of the twelve scenarios failed to attain thermal comfort, two of those instances were optimal in this simulation. Those instances involved the return diffuser behind the patient and airflow of 9 ACH, the minimum recommended by previous studies. It should be noted that the ADPI remained unmet in these cases, revealing complexities in achieving ideal thermal conditions in healthcare environments. This study extends the insights from our prior research, advancing our understanding of ventilation impacts on thermal comfort in healthcare facilities. It underscores the need for comprehensive approaches to environmental control, setting the stage for future research to refine these findings further.

Rapid prediction of indoor airflow field using operator neural network with small dataset

Indoor airflow is one of the most critical factors affecting room comfort. The accurate prediction of indoor airflow fields is essential for efficient environmental control. However, representative methods for calculating indoor airflow organization, such as computational fluid dynamics (CFD), are complex and time consuming. Therefore, this study proposes a machine learning approach that can rapidly reconstruct indoor airflow fields. This method employs an improved deep operator network (DeepONet) and a Fourier neural operator (FNO) neural network to learn a set of solutions to a problem resembling a flow field and then realizes an accuracy-preserving prediction of an unseen domain. First, we decompose the computational domain into subdomains and then reconstruct the flow field for the subdomains. Subsequently, the subdomains are stitched into the original computational domain. Using data enhancement techniques along with a small dataset, this method achieves satisfactory training results. The results indicate that for a two-dimensional isothermal flow field problem, both the improved DeepONet and FNO models accurately reconstruct the flow field. The mean squared errors are 0.28% and 1.89% for the improved DeepONet and FNO models, respectively, with both requiring less than 0.01s. This method does not require repeated training under different operating conditions, which significantly reduces the computation time. Compared with conventional CFD technology, the proposed method improves the speed by up to three to six orders of magnitude.

Ambulatory Patient Satisfaction Indicators at Tugurejo Regional General Hospital in Semarang City

Tugurejo Hospital is a Type B hospital operated by the regional government of Central Java Province. Each year, the hospital conducts patient satisfaction surveys. Between 83% and 94% of patients report being satisfied with the services provided by the hospital; however, there is a large variation in patient satisfaction between types /departments. Ambulatory (outpatient) services continue to see an increasing number of patients per day. While most existing research focuses on the factors influencing patient satisfaction, there is a pressing need for research on patient satisfaction indicators. Such research is crucial as it provides hospitals with practical tools and references to assess and improve patient satisfaction. This study aims to identify indicators of ambulatory patient satisfaction in Tugurejo Hospital. This observational study employs a quantitative approach. Data were collected cross-sectionally using a questionnaire and analysed descriptively and through principal component analysis. the sample consisted of 150 ambulatory patients. The highest levels of satisfaction were for customer service officers (98.7%) and waiting room comfort (98.7%), while the lowest satisfaction was for service announcements (58.7%). All measured variables were found to be related to ambulatory patient satisfaction. There were 65 satisfaction items with an extraction value above 0.800. Four components were identified: service products, the behaviour of hospital staff, communication, and hospital facilities. A total of 26 satisfaction indicators were identified. The hospital should review these indicators and findings to continue improving patient satisfaction.

Dynamic Operation Planning Model of Air-Conditioning Based on Weather Forecast: Heat Resource Usage Considering Energy Saving and Room Comfort

Air-conditioning systems must save energy while maintaining an appropriate room environment. In heat management, there is a tradeoff between the requirement to save energy during heat production and individual heat consumption for maintaining comfort. Heat consumption is dependent on environmental conditions in a given room, including the thermal load of the room and ambient weather. To predict thermal load, regression models can be built using weather forecast data, and the heat level necessary to avoid heat stroke while maintaining comfort can be calculated. In this study, we propose a decision-making process model of heat resource allocation for facility managers, known as a dynamic air-conditioning operation plan. The heat level allocated may change, considering the gap between planned and actual heat usage on a daily and monthly basis, and the resource is then distributed according to the thermal load. If the actual heat usage is expected to exceed the monthly target by the middle of the month, the plan is then revised to use the heat resource allocated for the following month, ahead of schedule. To demonstrate effectiveness of the model, sensitivity analysis was performed based on measured data.

Evaluation of space comfort based on occupant satisfaction in west Jatinegara flats residential units

The Special Capital Region (DKI) of Jakarta is an area that experiences population growth every year, which raises the number of housing-related needs and reduces the amount of available vacant land for housing. In order to get around the lack of land for housing, a plan for flats—like the West Jatinegara Flats—must be implemented. The spaces in an apartment that are designed by an architect are required to produce a design that takes into account the comfort factor of the space for the occupants or users in addition to aesthetics. Residents feel comfortable if they are at a thermal temperature of between 22.8℃-25.8℃ with humidity of 70%. The study, "Evaluation of Space Comfort based on Occupant Satisfaction in West Jatinegara Flats Residential Units," attempts to ascertain whether or not improving strategies are required to raise space comfort based on occupant satisfaction and whether or not an appropriate level of space comfort is achieved. This study employs the quantitative method, which entails gathering primary and secondary data and conducting interviews with at least 10% of the resident population selected at random. This study's results indicate that improvement strategies are required to improve room comfort. These strategies include organizing each room to make it cozier and more compact, considering the type of opening material, the opening area ratio, and the materials used for the glass and frame to prevent breakage and damage to the windows and handles. Every room in the residential unit needs to have optimal air exchange during strong wind conditions.

Model predictive control of heating in a low energy single-family house

This paper presents a control scheme that uses a Model Predictive Control (MPC) approach to manage the heating system of a low-energy single-family house. The house is equipped with an air-to-water Heat Pump (HP) and individually controlled hydronic underfloor heating circuits for each of its 11 heating zones. The MPC scheme is designed to maintain individual room comfort levels in each zone, while incorporating weather forecasts and following a heating reference to allow for load shifting for periods with low energy prices and high Photovoltaic (PV) production calculated by an upper level in a hierarchical control scheme. The focus of the design has been the model structure that allows for fast solutions to the MPC optimisation problem, while still capturing the high complexity, non-linear dynamics of the building. The controller is tested on a high-fidelity simulation model of the house, achieving disturbance rejection and system stabilisation. The rapid solving time makes repeated experiments and longer simulations feasible.
