Research on Energy Efficiency Optimization Control Strategy of Office Space Based on Genetic Simulated Annealing Strategy

Current energy-saving lighting control algorithms often face the dilemma of local optimality, which limits the energy-saving potential and comfort improvement of indoor lighting systems. The control parameters of the lighting system are optimized using a genetic simulated annealing algorithm to achieve the global optimal solution and enhance energy-saving efficacy in indoor lighting. The local search ability of the algorithm is enhanced by simulated annealing processing of excellent individuals after genetic operation. The genetic probability is adaptively adjusted according to the number of iterations and the fitness of the population, so that the algorithm enriches the population diversity in the early stage and avoids the “premature” convergence of the algorithm. A lamp illuminance model based on an artificial neural network and an indoor natural illuminance model based on a workbench are proposed to evaluate the lighting comfort, which provides a basis for constructing the fitness function of the optimization algorithm. Through the simulation experiment, the genetic simulated annealing algorithm is applied to the lighting scene introduced in this paper and compared with the traditional particle swarm optimization algorithm and genetic algorithm, the lighting energy saving performance is significantly improved.

Effects of Light Conditions on Tunnel Construction Workers’ Quality of Life and Work Productivity

Higher lighting intensity promotes workers’ productivity but few studies focus on the problems caused by lower lighting intensities at tunnel construction sites without natural light. The purpose of this study is to explore the relationship between light intensity and workers’ sleep quality, alertness, vitality, and work productivity through a theoretical structural equation model based on the literature review. Data were collected through a questionnaire survey, and 5792 valid responses were adopted for the analysis. First, the results showed that greater lighting intensity promoted workers’ productivity directly and indirectly through three mediators: sleep quality, alertness, and vitality. Then, the whole sample was classified into four groups: high intensity/high comfort, moderate intensity/moderate comfort, moderate intensity/low comfort, and low intensity/low comfort. The clustered results showed that the lighting conditions of tunnel construction sites were generally poor and that lighting comfort promoted workers’ productivity to some extent. Besides, the influence of lighting intensity on productivity declined with improved lighting conditions while the impact of lighting intensity on workers’ physiological and psychological status showed differing trends as lighting conditions varied. However, the relationships between workers’ physiological and psychological status and productivity remained stable regardless of the lighting conditions. The findings could provide a reference for developing corresponding measures to promote workers’ productivity.

Passive Design Strategy of Vertical Housing for Optimizing Energy Efficiency

Abstract Passive design is crucial for sustainable building, maximizing comfort while minimizing energy use and environmental impact. It optimizes heating, cooling, ventilation, and lighting through natural energy sources like sunlight and wind, promoting responsible energy consumption. As the Indonesian economy continues to grow, urbanization rates in major cities are rapidly increasing, leading to urban sprawl. One proposed solution is densification through vertical housing construction. However, a concern with vertical housing is the energy consumption for thermal and lighting comfort, particularly in Indonesia’s tropical climate. Passive design presents an effective energy efficient solution for optimizing comfort in vertical housing. This study explores various passive design strategies based on six basic principle. Firstly, it presents local climatic conditions. Then, it discusses lessons learned from traditional buildings and modern buildings. Finally, it introduces a passive design method for high-rise housing, focusing on six points: massing and orientation, building envelope, passive cooling, thermal mass storage, natural air circulation and daylighting. The study presents results and potential recommendations for passive design to optimize energy efficiency.

METHODS FOR MANAGING VISUAL QUALITIES OF LIGHTING IN PUBLIC SPACES OF THE CITY

Raising of problem. Lighting is an important aspect of creating an attractive and comfortable urban environment. It can enhance the aesthetics of night-time cities by highlighting architectural details, highlighting significant urban locations and creating areas for public interaction. Properly designed lighting affects the health and comfort of citizens. It can improve mood, sleep, reduce fatigue and improve visual function. With the development of new lighting technologies and digital innovations, it becomes possible to introduce modern approaches to urban lighting planning into architectural practice.At the present stage of innovative development of street lighting technologies, the Urban Lighting Masterplan (ULMP) is playing an increasingly important role. These are strategies that regulate and fix the basic requirements for organizing sustainable artificial lighting in urban spaces. Purpose. This study is devoted to the principles of managing the visual qualities of the illuminated architectural environment. For the first time, a framework for the formation of criteria for assessing the visual qualities of the architectural environment is proposed. GIS is considered as a promising tool for managing the visual qualities of lighting, the levels of which are formed in accordance with the functions of visual comfort. The following nine basic functions of visual comfort are defined, each of which is the basis for creating GIS layers: 1. Adaptive; 2. Axiological; 3. Compensatory; 4. Integrating; 5. Aesthetic; 6. Cultural; 7. Social memory function; 8. Epistemological; 9. Ethical. Each subsequent layer adds its own light sources. For each of these nine functions, two lighting properties are proposed: color and light. Each property is described by four characteristics: color − saturation, lightness, color temperature, color tone; light (luminous flux) – brightness, illumination, contrast. Conclusion. An idea of the approaches and structure of the assessment of the visual qualities of illuminated public spaces has been formed. It is hypothesized that the optimal approach to the analysis of existing situations in the lighting of open public spaces and the formation of sets of requirements for improving their visual qualities is the use of GIS. A hypothesis was formed about the structure of the criteria for assessing the visual qualities of lighting, based on the psychophysiological, emotional-aesthetic, and pictorial-artistic levels of perception of the architectural environment.Thus, the approach described in the article allows us to formulate criteria for assessing the visual comfort of artificial lighting of public spaces.

Analisis Standar Penerangan pada Gedung IDB Laboratory FMIPA UNESA Berbasis Visual Basic 6.0

Lighting is a major requirement in human life to be able to see objects around clearly, lighting is obtained from natural light sources and artificial light sources. The IDB laboratory building of the FMIPA UNESA has many rooms with different functions and uses, so the lighting of each room must be adjusted to the Indonesian National Standard (SNI 03-6575-2001). Therefore, a program is needed to analyze and determine the number of lights used quickly and accurately in order to achieve safe and comfortable lighting according to (SNI 03-6575-2001). In this case the method used is to use the calculation of the visual basic 6.0 program by inputting the dimensions of each room, namely length, width, height, and the type of artificial lighting used. Based on the results of the calculation of the lighting standards of the IDB building using the visual basic 6.0 program, it is known that only the prayer room on the 1st floor, the microscope room on the 2nd floor, the warehouse on the 1st, 2nd, 3rd and 4th floors and the microteaching room on the 2nd, 3rd and 4th floors meet SNI 03-6575-2001. Whereas for other rooms such as libraries and laboratories cannot meet SNI 03-6575-2001 so that action needs to be taken so that they can meet the standards, namely by increasing the number of lighting points in each room, or it can also be by replacing the type of lighting with a larger lumen value than before.

Enhancing Thermal and Daylight Performance of Historic Buildings with Passive Modifications; A Tropical Case Study

Historical buildings worldwide hold immense potential for adaptive reuse within the framework of the circular economy, a concept gaining traction in the building construction industry for its role in reducing carbon emissions. Many of these structures boast passive building design strategies, which inherently lower energy demands. Among these, thermal mass and daylight harvesting emerge as pivotal strategies for achieving indoor thermal and visual comfort, respectively. However, with the advent of significant climate change and evolving built environments, the efficacy of these historical passive strategies is subject to debate. This study focuses on a residential building constructed in the 17th century by Dutch settlers in Galle, Sri Lanka, serving as a case study. The research targets improvements in both thermal and visual comfort. Thermal performance analysis was conducted through air temperature measurements, revealing a notable 3-hour time lag and a 2.5°C reduction in peak air temperature during the day. Conversely, nighttime measurements indicated a rise in indoor temperature compared to ambient conditions. Using Design Builder software, the building was modelled to assess its daylighting conditions. Drawing upon thermodynamic principles and daylight harvesting techniques, the study proposes building envelope interventions and ventilation strategies to address nighttime overheating and enhance daylight utilization. The results demonstrate that these modifications can potentially reduce nighttime heat by 2-3°C, while also decreasing the energy requirement for lighting comfort from 51.10 kWh/m² per annum to 44.84 kWh/m² per annum. This research showcases the effectiveness of judiciously implemented interventions in historical buildings, illustrating tangible improvements in both thermal/visual performance and energy efficiency. Leveraging inherent qualities of historical structures and integrating modern design strategies to these buildings can play a vital role in sustainable urban development and energy conservation efforts.

The Use of Transparent Structures to Improve Light Comfort in Library Spaces and Minimize Energy Consumption: A Case Study of Warsaw, Poland

Light plays a key role in shaping the quality and atmosphere of interior spaces, and its importance and contradictions are amplified in the design of libraries. This study focuses on the problems associated with both insufficient natural light and excessive light. In both cases, visual discomfort is the result. The reason for these problems lies in the use of translucent structures with different parameters and properties in library architecture. This study analyzed the lighting environment in the main reading rooms of two university libraries in Warsaw. The research methods were based on a field survey of objects and an analysis of the architectural and construction parameters of the premises, as well as the physical and mechanical properties of various types of translucent materials used in the reading rooms. The results of this study shed light on the relationship between the interior space of the reading room and the geometry of transparent structures, as well as the effectiveness of daylighting in libraries in the natural conditions of Warsaw. The key point of the present study was to recognize the critical role that transparent materials and structures play in mitigating potential operational problems in library spaces. Wise selection of these elements at the design stage can help minimize problems related to thermal energy regulation, ventilation control, acoustic insulation, and increased visual comfort. The importance of this research area lies in its potential to optimize library buildings by increasing energy efficiency and reducing reliance on artificial lighting, heating, and air conditioning. Careful consideration of transparent materials at the design stage promises long-term benefits in the form of sustainable library spaces that not only meet functional requirements, but also contribute to a more environmentally conscious architectural landscape.

A delignified longitudinal-cutting poplar veneer-based epoxy resin composite with excellent transmittance, haze, flexibility and wood fiber art texture

A delignified longitudinal-cutting poplar veneer-based epoxy resin composite (TLPE) with excellent transmittance, haze, flexibility and wood fiber art texture, that was prepared by delignifing longitudinal-cutting poplar veneer (LPV) and filling the delignified LPV with epoxy resin (ER). The TLPE has retained the porous structure and wood fiber art texture of LPV due to the fact that it is not completely filled with resin. The changed benzene skeleton and the ether (C-O-C) were found in the TLPE, that should be due to the chemical combination between the benzene of filled ER and the cellulose of delignified LPV, and the chemical reaction between the benzene and the cellulose yielded the C-O-C. Parts of the TLPE that are completely filled with the ER, that can reach a transmittance of approximately 90 % and a haze of approximately 90 %. Moreover, due to the combined action between the fibril of delignified LPV and the ER, the TLPE has high refractive index fluctuation in the perpendicular direction of fiber and excellent flexibility (the elongation at break: 15 %). When the TLPE is used as the building material, the TLPE can provide a comfortable lighting effect after the light passes through it, it can also accommodate various streamlined and natural artistic shapes with wood fiber art texture in buildings, and it can also achieve a balance between science and art in the building through its optical, styling, and textural advantages.

Correlation between brain activity and comfort at different illuminances based on electroencephalogram signals during reading

The impact of light comfort on user health and productivity is profound, and brain activity serves as a sensitive indicator of how light environments influence individuals. This study establishes the correlation between light comfort and brain activity by utilizing time-frequency domain features and nonlinear dynamic features extracted from electroencephalogram (EEG) signals during reading. The experiment was conducted at three illuminance levels (200 lx, 500 lx, and 1000 lx) and involved collecting EEG signals and subjective evaluations from 28 young college students. Analysis of key EEG features under varied illuminances included average power, power distribution across different brain regions and frequency bands, fuzzy entropy, and avalanche parameters. The results demonstrate that at 500 lx, significant activation occurred in oscillatory activity within the prefrontal lobe and the β band. This illuminance level was identified as the most comfortable, with the lowest power observed at 2.34 μv2. Additionally, the avalanche criticality index was lowest (1.68) at 500 lx, indicating a stable and healthy brain state. Light comfort was significantly correlated with the relative power of δ and θ in parietal lobe and β in occipital lobe. The multilayer perceptron (MLP) model, trained on EEG features, achieves an 83.3% accuracy in predicting light comfort, with a notable 12.7% improvement when using only the 10 significantly correlated features compared to the full set. This study provides a method for using EEG signals to predict user light comfort under different illuminances and offers insights for the design of personalized indoor lighting environments.

Influence of Sun Shading Devices on Energy Efficiency, Thermal Comfort and Lighting Comfort in a Warm Semi-Arid Dry Mediterranean Climate

The dry Mediterranean climate (BShs) is the European region with the highest number of hours of sunshine per year. The high annual solar radiation makes sun shading devices necessary to comply with current energy efficiency standards. However, these standards do not sufficiently consider their effect on the indoor lighting comfort of buildings. The objective is to qualitatively and quantitatively determine how movable sun shading devices jointly influence the energy efficiency, thermal comfort and lighting comfort of buildings in BShs climate. The scientific novelty of the work consists of demonstrating the limitations of the sun shading systems commonly used in southeastern Spain and determining the optimal technical solution in this climate to simultaneously improve thermal and lighting comfort. This research comparatively studies the influence of various movable sun shading systems on the daylighting and thermal performance of an educational building. This study conducted on-site measurements, user surveys and computer simulations to study how to improve the thermal and lighting performances of the building. This work demonstrates that interior solar shading provides little improvement in thermal comfort and reduces the cooling demand by only 25%. External movable sun shading improves thermal comfort and reduces the cooling demand by more than 60%, but only adjustable blinds or awnings achieve adequate and homogeneous illuminance values as they diffuse daylight. The paper concludes that energy efficiency standards should be modified to ensure adequate lighting comfort in buildings.

Integrated Systems of Light Pipes in Buildings: A State-of-the-Art Review

Artificial lighting comprises nearly one-third of the total electrical load of buildings, resulting in significant carbon emissions. Reducing the carbon emissions caused by artificial lighting is one of the ways to achieve low-carbon buildings. To meet the demand for high-efficiency, energy-saving, and comfortable lighting, light pipes are increasingly used in buildings. This paper reviews the research and development of light pipes and integrated technology. Sky conditions as a dynamic factor always affect the performance of light pipes. The combination of light pipes and an artificial lighting system can effectively solve this problem. A light pipe can be integrated with a ventilation stack to achieve the ventilation and cooling or heating of a building. A lighting-heating coupled light guide can improve the energy efficiency and sustainability in buildings, such as where antimony tin oxide nanofluid is introduced to absorb additional heat and then provide domestic hot water. The application of a photocatalyst to light pipes can realize air purification and self-cleaning. The use of light pipes does not consume electricity and can reduce the time spent using artificial lighting, thus allowing for power savings. From a whole life cycle perspective, the use of light pipes can be a balance of cost and benefit. In conclusion, such information could be useful for engineers, researchers, and designers to assess the suitability of applying integrated light pipes in different building types and examine the potential of energy and cost savings.

GA-BP based daylight prediction and sensor placement in residential areas

This paper conducts a comprehensive analysis of the light environment in different areas of residential houses located in Beijing’s Guangyuanli neighborhood. The main objective of this study is to assess the contribution of natural daylight to residential illuminance, with the aim of providing a foundation for reducing energy consumption and enhancing light comfort. While previous research predominantly focused on sensor deployment in single scenes such as offices and classrooms, these approaches are inadequate for multi-scene analysis of daylight in residential areas. Moreover, traditional deployment methods can negatively impact the quality of life and everyday living experience. To overcome these limitations, a prediction model is developed to estimate ceiling and window illuminance, as well as work surface illuminance in various scenes within residential buildings. The Dialux software is employed for data simulation, and a GA-optimized BP neural network is utilized to train the model, establishing the mapping relationship between input variables and corresponding illuminance outputs. By inputting sensor values from different scenarios into the model, the predicted daylight illuminance values can be obtained. This predictive approach facilitates the evaluation of light comfort and energy consumption reduction in different functional areas of residential buildings.

High thermal stability and quantum efficiency of (Sr,Ba)2Ga2SiO7: Eu2+ phosphors for full-spectrum WLEDs

High-quality phosphors with color tunability are urgently needed for the full-spectrum white light-emitting diodes (WLEDs) with healthy and comfortable lighting like the solar spectrum. Here, a Sr2Ga2SiO7: Eu2+ phosphor with tunable luminescence color is reported, achieving a luminescence tuning from maize-yellow to yellow by changing the Eu2+ ion concentration. Importantly, the quantum efficiency of BaSrGa2SiO7: 1.0 % Eu2+ is as high as 85.7 % compared with 49.1 % of Sr2Ga2SiO7: 5.0%Eu2+, and the emission intensity of BaSrGa2SiO7: 1.0 % Eu2+ retains 92 % of the room temperature (RT) emission intensity at 473 K by Ba2+ substitution. Furthermore, the increase of Ba2+ ion concentration also makes the phosphor achieve tunability from yellow to green. The as-prepared full-spectrum WLEDs exhibits a continuity spectrum like solar spectrum with an extremely high color rendering index of 93.5 and low correlated color temperature of 4562 K. This work provides new insights into the exploration of new phosphors for high-performance full-spectrum WLEDs devices.

Spectral tunability of K2Lu(WO4)(PO4): Dy3+, Eu3+ phosphors and remote luminescent layers for high-quality white light

Dy3+ and Eu3+ co-doped phosphors have been emerged as potential candidate to generate high-quality white light under the ultraviolet (UV) or near ultraviolet (NUV) excitation for health and comfort lighting. Herein, K2Lu(WO4)(PO4) crystal has been newly developed to accommodate rare earth ions, such as Dy3+ and Eu3+ ions, to achieve spectral tunability of high-quality white light. Under NUV excitation, Dy3+ singly-doped K2Lu(WO4)(PO4) phosphors exhibit the desired blue emission at 486 nm and yellow emission at 575 nm, attributed to the electric dipole transition 4F9/2 → 6H15/2 and the magnetic dipole transition 4F9/2 → 6H13/2 transitions of Dy3+ ions, respectively. Interestingly, the emission color can be facilely adjusted from cold white light to pink light under 365 nm NUV excitation due to the co-doping of Eu3+ ions in K2Lu(WO4)(PO4): 0.05Dy3+ sample. Further, the remote luminescent layers containing K2Lu(WO4)(PO4): 0.05Dy3+, 0.20Eu3+ phosphor can be printed on glass substrate by screen printing technique to generate high-quality white light with the correlated color temperature (CCT) of 5433 K and color rendering index (CRI) of 87. Moreover, the remote luminescent layers exhibit better heat dissipation performance compared to conventional encapsulated LEDs and can be used as a multicolor emitting candidate for high-power white LEDs.

Combined influence of multi-sensory comfort in winter open spaces and its association with environmental factors: Wuhan as a case study

Open space comfort significantly affects urban well-being, particularly in dense areas. This study uses drone imagery, climate measurements, and questionnaires to explore acoustic, aesthetic, light, thermal and overall comfort in Wuhan's pedestrian street, plazas, and parks, which proposing a hypothesis in both morphological factors and meteorological factors collectively influence comfort senses, and subsequently, overall comfort. The results indicate the sky view factor (SVF) contributes to all the comfort senses. Spaces with SVF over 32.9 % have 170 % higher light comfort and 160 % higher thermal comfort than those below 13.3 %. As SVF change from under 13.3 % to over 32.9 %, mean aesthetic comfort vote increases by 134 %, while acoustic comfort declines by 36 %. With Universal Thermal Climate Index (UTCI) from below 11.5 °C to higher than 21.5 °C, aesthetic comfort's influence weight on overall comfort rises by 85.4 %, while thermal comfort decreases by 32.4 %, indicating a falling importance of thermal but increasing that of aesthetic comfort with warmer environment. Also, the study emphasizes higher “cross-modal effects” between aesthetics and acoustic comfort compared to sunligt and thermal comfort. Research will help inform improvements to outdoor environments in similar climates.

Study on Improving the Energy Efficiency of a Building: Utilization of Daylight through Solar Film Sheets

Daylight can contribute to substantial reductions in the energy consumed by artificial lighting applications. However, issues such as visual comfort, illumination intensity, and availability represent major issues when daylight is relied upon to illuminate buildings. There are many technologies that are used to control received sunlight and minimize its side effects. The placement of solar film sheets on window glass is a common and popular method utilized in many buildings to minimize electric lighting energy consumption without causing undue visual discomfort to occupants. To examine the practicality of this application and its effect on room lighting, a modern office was selected in which to conduct this field study. Two measures were used to evaluate this technique: firstly, field measurements and their comparison to the specified standard illumination levels; and secondly, a short-form questionnaire survey conducted to obtain occupants’ opinions of the office lighting. Actual measurements were conducted in the selected office spaces, with and without applying solar control film coating on the window glass. Indoor luminance levels and lighting comfort were systematically recorded and analyzed. The findings of this study show that using a solar film with a visible light transmittance of 50% can achieve savings in energy consumption of up to 33% if utilized as part of an integrated lighting system.

Lighting and thermal factors on human comfort, work performance, and sick building syndrome in the underground building environment

The development of underground space can help cities solve problems such as the unmet demand for land and space. However, there are still many problems to be solved. The comfort of lighting and thermal environment, high work performance, and low prevalence of SBS symptoms play irreplaceable roles in creating a good indoor environment. The main purpose of this study is to investigate the differences in the comfort of lighting and thermal environment, work performance, and SBS symptoms among people living in underground spaces for long and short periods, and to provide optimal temperature and illuminance ranges for balancing these three aspects. A summer survey was conducted in subway stations, including measurements of environmental and physiological parameters, and psychological responses. A total of 952 questionnaires were collected for data analysis. The results show that the comfort of lighting and thermal environment for short-stay occupants is more sensitive to changes in indoor air temperature and illuminance. Reduction of indoor air temperature can improve occupants’ work performance and can reduce SBS symptoms. The optimal temperatures for long-stay and short-stay occupants are 25.6–26.3 °C and 24.5–24.8 °C (or 24.5–25.1 °C), respectively. The optimal illuminance ranges for long-stay and short-stay occupants are > 300.0 lx and > 494.0 lx, respectively. The results of this research contribute to the creation of healthy, comfortable, and beneficial indoor environments in shared underground building spaces.

These results consolidate this intervention as a highly replicable and energy efficient alternative for similar infrastructures.

Intensified synthetic approach for GdYAG:Ce phosphors with ultrahigh color rendering toward healthy lighting

AbstractProcess intensified synthetic approach for synthesizing gadolinium and cerium co‐doped yttrium aluminum garnet (GdYAG:Ce) phosphors in white light‐emitting diodes (wLED) is developed. By using a high‐gravity rotating packed bed (RPB) reactor for preparation of sol–gel precursors, the significantly enhanced molecular mixing allows precise control and tuning of dry gel with designed structure to obtain nanosized particles of GdYAG:Ce precursors, which are prone to low temperature quick sintering process and therefore reduce the energy consumption of the electric furnace 76% compared to solid phase method. By analyzing the effect of cycling times and high gravity levels of RPB reactor on sintering and crystallization, sintering condition for emission spectrum adjustable GdYAG:Ce phosphors is optimized. Prototype devices based on blue chips and GdYAG:Ce phosphors exhibit high color rendering index of 83.8 and low correlation color temperature of 5357 K that are beneficial for creating a healthy and comfortable lighting environment.

A Distributed Intelligent Lighting Control System Based on Deep Reinforcement Learning

With the rapid development of human society, people’s requirements for lighting are also increasing. The amount of energy consumed by lighting systems in buildings is increasing, but most current lighting systems are inefficient and provide insufficient light comfort. Therefore, this paper proposes an intelligent lighting control system based on a distributed architecture, incorporating a dynamic shading system for adjusting the interior lighting environment. The system comprises two subsystems: lighting and shading. The shading subsystem utilizes fuzzy control logic to control lighting based on the room’s temperature and illumination, thereby achieving rapid control with fewer calculations. The lighting subsystem employs a Deep Deterministic Policy Gradient (DDPG) algorithm to optimize the luminaire dimming problem based on room illuminance in order to maximize user convenience while achieving uniform illumination. This paper also includes the construction of a prototype box on which the system is evaluated in two distinct circumstances. The results of the tests demonstrate that the system functions properly, has stability and real-time performance, and can adapt to complex and variable outdoor environments. The maximum relative error between actual and expected illuminance is less than 10%, and the average relative error is less than 5% when achieving uniform illuminance.
