A polymer-dispersed liquid crystal (PDLC) film is a device that can transition from opaque to transparent when electrically charged. These films be used as actuators control light levels in response changing natural light. However, the current state of art for controlling PDLC limited on/off functionality, and few works body literature have explored continuous control. This study develops novel nonlinear model PDLCs context feedback also demonstrates model’s utility by comparing experimental data with proportional–integral (PI) controller disturbance rejection tracking desired setpoint. development motivated need smart greenhouse provide programmable optimized plant growth. Specifically, sensor composed circuit photodiodes calibrated photosynthetically active radiation range.

Energy Efficiency in Buildings: Smart Glass Technology Evaluation and Selection Model

Energies, Год журнала: 2025, Номер 18(7), С. 1798 - 1798

Опубликована: Апрель 3, 2025

In the context of architecture and construction industries implementing environmentally friendly sustainable solutions, smart glass is also designed using materials operations, contributing to environmental protection efforts. The application in large buildings optimizes buildings’ operation, helping reduce reliance on air conditioners that consume amounts electricity emit significant CO2 into environment. Additionally, enhances energy-saving efficiency by intelligently regulating indoor temperature natural lighting, thereby reducing overall energy consumption operational costs. this study, authors propose a fuzzy multi-criteria decision-making (MCDM) model evaluate select optimal technology based technical, environmental, economic, social criteria. integrates analytic hierarchy process (FAHP) calculate weights criteria Interactive Multi-criteria Decision-Making Portuguese Model (TODIM) rank different alternatives. findings highlight most suitable technology, offering benefits while ensuring aesthetic appeal durability. This study provides comprehensive approach integrating sustainability design, development green energy-efficient buildings.

A review of complex window-glazing systems for building energy saving and daylight comfort: Glazing technologies and their building performance prediction

Journal of Building Physics, Год журнала: 2024, Номер unknown

Опубликована: Сен. 13, 2024

The increasing energy consumption and detrimental CO 2 emissions contributing to global warming underscore the urgent necessity for conservation, especially within buildings. Among different building components, fenestration plays a pivotal role as it accounts majority of heat transfer across envelope. This emphasises significance window-glazing technologies in enhancing their thermal performance. Furthermore, systems can lead overheating issues, particularly summer, glare winter. These challenges have spurred development various advanced glazing systems. paper provides comprehensive review these based on functionalities working principles, with focus parameters such U-value, solar gain coefficient visible transmittance. technologies, vacuum aerogel exhibit superior insulation properties, U-values below 1 W/m K, making them suitable heating-dominated climates. Smart window systems, electrochromic windows, are ideal cooling-dominated climates due low (0.09–0.47) transmittance (0.02–0.62). Photovoltaic not only provide effective shading but also produce additional power on-site use. Some feature complex structures, which present when integrating into existing simulation software assess impact Therefore, this examines techniques conducting daylight performance simulations buildings that make use Ultimately, authors propose an approach characterise thermal, optical electrical properties photovoltaic system software, EnergyPlus. facilitates thorough investigation effects efficiency indoor comfort.
