Guidance to avoid health risk caused by energy saving measures in homes

Due to extreme increases in energy prices in European countries (as well as other non-European countries), building users may be tempted to take energy saving measures because they can no longer pay their energy bills. This in turn may have adverse effects on the indoor air quality - especially in older and badly insulated homes. This article gives some elementary advice on what people should and shouldn’t do in cold and temperate climates where indoor heating is normally needed in winter.

Comparing indoor air quality in naturally ventilated and air-conditioned hospitals in the tropics

Occupant exposure to airborne pathogens in buildings can be reduced by a variety of means, including adequate provision of outdoor air by ventilation. This is particularly important in buildings, such as hospitals, which may house a higher number of infected individuals relative to the wider population. In tropical Africa, however, there is evidence that new hospitals built with air-conditioning to cope with the extreme heat are poorly ventilated compared to existing hospitals that were designed to be naturally ventilated.

Application of Indoor Carbon Dioxide During the COVID- 19 Pandemic

In response to the COVID-19 pandemic, many organizations have recommended improved ventilation to reduce the risk of indoor airborne infectious disease transmission. These recommendations include increasing outdoor air rates and filtration efficiencies, as well as verifying that ventilation systems are operating as intended. There have also been many recommendations to monitor indoor CO2 concentrations as indicators of ventilation or infection risk, in some cases with quantitative concentration limits.

Evaluation of ventilation performance and compliance with Belgian covid-19 guidelines in sport infrastructure

During the corona-19 pandemic waves in 2020 and 2021, many cultural and recreational activities inside buildings could no longer take place to prevent virus transmission. In order to allow cultural and recreational sectors to reopen in a safe way by the summer of 2021, a ventilation task force of the corona commissioner's office of the Belgian federal government prepared recommendations for the practical implementation and monitoring of indoor air quality in the context of COVID-19.

Using a solar air heater to ventilate classrooms during the winter season in New Zealand: a potential alternative solution to assist during COVID 19 outbreaks

Ninety per cent of New Zealand classrooms are naturally ventilated by opening windows. Achieving a suitable ventilation level will rely on teachers. A survey showed that less than half of the teachers opened windows during teaching time. Due to the high occupant density in classrooms and a low natural ventilation rate, it is challenging to provide adequate ventilation during the southern hemisphere winter months (June to September). From 9 am to 3 pm, school hours align well with the optimum solar radiation, providing opportunities for solar ventilation.

Performance and Costs of Air Sealing and Ventilation Measures for Home Decarbonization in the US

In order to get to scale and rapidly decarbonize the energy use of homes, we need information on the performance and costs of potential home upgrade measures. The costs for different performance levels are vital for energy savings and decarbonization program planning and to focus R&D activities on measures that could achieve significant cost reductions. This study obtained data from over 1,700 projects that aimed to achieve advanced levels of energy use and related carbon emissions reductions.

Integration of Domestic Ventilation Systems with Vertical Axis Wind Turbine Ventilation Technology

The use of natural ventilation components as an enhancement for the ventilation systems has become more desirable in the building sector. The natural ventilation systems play a crucial role in reducing the carbon footprint from space heating and cooling through applications of low carbon technology and heat recovery unit. Low carbon technologies such as windcatchers and turbine ventilators are commonly used in commercial, educational, and industrial buildings for providing thermal comfort within a building and minimising carbon emissions.
