Abstract

This study aims to investigate the natural lighting performance of typical educational school premises in Cyprus and propose solutions to improve the visual comfort in classrooms. Natural lighting is an important factor in the design of education buildings as it creates a pleasant environment, it promotes healthier conditions and ensures energy saving. For the purposes of the present research, an in-depth lighting performance analysis was carried out in a typical classroom in Cyprus. A field study carried out through a questionnaire-based survey, as well as through static and dynamic simulations, assessed the lighting performance and visual comfort in educational buildings in Cyprus. The study shows sufficient lighting levels in classrooms in all orientations; however, high lighting contrast and bright visible light source in the field of view causes glare issues, especially in classrooms with east- and west orientation. Conclusions regarding potential improvements are proposed in order to achieve better visual comfort in typical educational school premises in Cyprus and in other areas of southern Europe with similar climatic characteristics and typologies in educational architecture.

A Reinforcement Learning-Based Approach to Automate the Electrochromic Glass and to Enhance the Visual Comfort

Raghuram Kalyanam, Sabine Hoffmann

Summary: Daylight is crucial for human well-being, but glare can be a problem in office buildings with large windows and glass facades. Traditional shading systems may not effectively adapt to changing sky conditions, while electrochromic (EC) glass offers better light transmission control. By using reinforcement learning with a DQN agent, glare scenarios can be avoided effectively, increasing the amount of useful daylight and reducing the need for artificial lighting.

Towards an integration of visual comfort and lighting impression: A field study within higher educational buildings

Zhe Kong, Ruyan Zhang, Jinghao Ni, Pengxuan Ning, Xingqi Kong, Jiayue Wang

Summary: Daylighting environments in higher educational buildings have a significant impact on students' vision health and learning efficiency. This study found that general daylighting predictors perform similarly to customized predictors in subjective assessments. The recommended predictors for effectively predicting individual perceptions of daylight sufficiency, desired lighting level adjustments, and degrees of daylighting stimulation are horizontal illuminance, vertical illuminance, mean luminance of an entire scene, and mean luminance of the horizontal 40 band.

Advancement on Thermal Comfort in Educational Buildings: Current Issues and Way Forward

Giulia Lamberti, Giacomo Salvadori, Francesco Leccese, Fabio Fantozzi, Philomena M. Bluyssen

Summary: The thermal environment in educational buildings plays a crucial role in students' health and productivity, with research showing that children often have different thermal sensations than adults. Future studies should focus on a more rational evaluation of thermal comfort, considering the effect that local discomfort can have on the perception of an environment and carefully assessing the relationships between HVAC systems, building envelope, and thermal comfort. Additionally, studies should also evaluate the impact of indoor air quality, acoustic, and visual quality on students' health and performance while considering possible individual differences.

MODERNISATION OF THE LIGHTING SYSTEM IN TREASURY OF THE TRETYAKOV GALLERY

Roman Milstein

Summary: The project aims to modernize the showcase lighting system in Treasury of the Tretyakov Gallery. The design allows for symmetrical and asymmetrical accent-lighting spotlights to illuminate both the vertical and horizontal surfaces of showcases, as well as narrow and ultra-narrow beams to highlight exhibits. The resulting controlled lighting system creates a hierarchical luminous environment with adjustable luminance levels. The hidden placement of luminaires ensures they are completely invisible to visitors.

Impact of lighting parameters on human comfortable feeling

Yehor Zheliazkov, Julia Yamnenko

Summary: Comfortable level plays a crucial role in human circadian rhytms and environmental perception. Lighting parameters should consider both the visual and nonvisual systems. This paper discusses the impact of lighting characteristics on these two systems and its implications for designing light in healthcare and medical applications. It also presents the results of an experiment conducted in a climate chamber, which can be used to develop a smart lighting control system that adjusts to human perception and circadian rhytms.

FROM THE HISTORY OF LIGHT AND ENGINEERING: ISSUES OF NATURAL LIGHTING IN THE SOVIET RESIDENTIAL ARCHITECTURE OF THE1920S-1930S

Anna V. Vasilieva, Julia L. Kosenkova, Mikhail Shubenkov

Summary: In the early 20th century, regulations and requirements regarding dwelling illuminance and insolation were established, with research on calculation methods intensively carried out in the Soviet Union from the late 1920s to the early 1930s. The interest of architects and light engineers in the optimal shape and area of window openings was influenced by the approach to housing construction as specific household production, although artistic considerations sometimes overlooked the importance of residential premise illuminance.

Estimating omnidirectional urban vertical wind speed with direction-dependent building morphologies

Qi Li, Jiayu Chen, Xiaowei Luo

Summary: This study focuses on the vertical wind conditions as a main external factor that limits the energy assessment of high-rise buildings in urban areas. Traditional tools for energy assessment of buildings use a universal vertical wind profile estimation, without taking into account the unique wind speed in each direction induced by the various shapes and configurations of buildings in cities. To address this limitation, the study developed an omnidirectional urban vertical wind speed estimation method using direction-dependent building morphologies and machine learning algorithms.

Model predictive control of distributed energy resources in residential buildings considering forecast uncertainties

Felix Langner, Weimin Wang, Moritz Frahm, Veit Hagenmeyer

Summary: This paper compares two main approaches to consider uncertainties in model predictive control (MPC) for buildings: robust and stochastic MPC. The results show that compared to a deterministic MPC, the robust MPC increases the electricity cost while providing complete temperature constraint satisfaction, while the stochastic MPC slightly increases the electricity cost but fulfills the thermal comfort requirements.
