Purpose Poor indoor air quality (IAQ) contributing to occupants’ health symptoms is a universal, typically ventilation-related, problem in schools. In cold climates, low-cost strategies improve IAQ naturally ventilated school are rare since conventional methods, such as window opening, often inappropriate. This paper aims present an investigation of relieve among occupants Finland. Design/metho...

Building energy analysis tools are available in many forms that provide the ability to address a broad spectrum of energy-related issues in various combinations. Often these tools operate in isolation from one another, making it difficult to evaluate the interactions between related phenomena and interacting systems, forcing oversimplified assumptions to be made about various phenomena that cou...

Recently, many studies have focused on studying indoor air quality, especially with the outbreak of COVID-19, which is one reasons for increased need to improve quality. Many ideas and applications are available incorporate nature into buildings quality (IAQ) thus secure a higher percentage natural ventilation pollution reduction. One these use "breathing walls" (BWs), envelope components based...

Residential and industrial buildings are significant consumers of energy, which can be reduced by controlling their respective Heating, Ventilation, Air Conditioning (HVAC) systems. Demand-based Ventilation (DCV) determines the operational times ventilation systems that depend on indoor air quality (IAQ) conditions, including CO2 concentration changes, occupants’ comfort requirements. The predi...

The article describes the results of the project "open source smart lamp" aimed at designing and developing a smart object able to manage and control the indoor environmental quality (IEQ) of the built environment. A first version of this smart object, built following a do-it-yourself (DIY) approach using a microcontroller, an integrated temperature and relative humidity sensor, and techniques ...

Indoor Air Quality (IAQ), particularly in educational facilities, is gainingconsiderable interest and a synonymous indicator towards evaluatinghuman comfort. Factors such as CO2 concentration, temperature, andhumidity play crucial parts determining an acceptable level of IAQ.Many studies have also demonstrated that the indoor air quality ofclassrooms affects students’ concentration performance....

Thermal comfort and indoor air quality (IAQ) of educational buildings can affect students’ academic performance well-being are closely related to ventilation energy consumption. Demands the environmental within classroom generally vary with education levels result in consumption accounting for a considerable proportion total use bulk buildings. Its huge energy-saving potential is attracting wor...
