A novel model based approach of an integrated ventilation and heating model for monitoring and control

Control of HVAC systems may reduce congestion of the electricity grid on district level by shifting energy demand of buildings and increase the self-consumption of local photovoltaic energy. To achieve an optimal control of ventilation, occupant behaviour should be taken into account. To describe occupant behaviour, usually black box models are used and typically need large amounts of high quality training data. Alternatively, use of physical relations allows for a good predictive power requiring less training data.

Real-life ventilation filter performance: final results of an in-depth study

Within the ventilation principle of buildings, the outdoor air is considered as a source of fresh, "clean" air. However, as we all know, this is not always the case. Although the outdoor air quality in our cities already improved, the concentrations of certain pollutants, especially particulate matter and peak pollutions of ozone (and its precursors nitrogen oxides and volatile organic compounds), remain problematic.

Urban microclimate impact on ventilation and thermal performance of multi-family residential buildings: two case studies in different climates and urban settings

Urban settings change the microclimate around buildings and resulting thermal comfort inside.  This paper presents a method to consider microclimatic conditions, especially the effect of wind variations around the building, which impacts natural ventilation rates and indoor operative temperatures.

Minimising Hospital Acquired Infections using Good Design: Future Trends

This paper touches on historic indicators of good hospital design such as sun, daylight and natural ventilation. Evidence is provided that recent trends in hospital design that lean towards more highly serviced buildings with fixed windows lead to higher levels of Sick Building Syndrome, nosocomial infections and SARS CoV-2 related infections and deaths than in naturally ventilated buildings with opening windows.

Revision of the ventilation part of EN16798-1 and -2

As part of the mandated standards for estimating the energy performance of buildings CEN 16798-1 and -2 was developed to provide input for the indoor environment (thermal comfort, air quality/ventilation, lighting, acoustic) to energy calculations and design of buildings with its heating, cooling, ventilation, and lighting systems. A revision of this standard has now been started.

Start of the Pandemic Preparedness Program through Ventilation - Knowledge Gaps and application of the results

Ventilation and air cleaning of interior spaces are promising methods for the reduction of airborne pathogen spread and may reduce the number of (airborne) infections. With this in mind, and in response to the 2020-2022 COVID-19 pandemic, the Dutch Ministry of Health, Welfare and Sport (VWS), in collaboration with TNO have initiated this research program focusing on ventilation (P3VENTI) as part of the larger Pandemic Preparedness Program of VWS (300 million Euros, annually).

ASHRAE Indoor Carbon Dioxide Position Document: What’s Next?

ASHRAE’s 2022 publication of a new position document on indoor carbon dioxide (CO2) has been a significant contribution to ongoing discussions of how indoor CO2 can be used to understand ventilation and indoor air quality (IAQ). The position document clarifies what is known about the relationship between CO2 concentrations and ventilation rates, the effects of CO2 on building occupants, and how CO2 concentrations relate to airborne infectious disease transmission. While the position document is a key step to addressing ongoing debate and

AIRBODS: Airborne Infection Reduction through Building Operation and Design for SARS-CoV-2

The Airborne Infection Reduction through Building Operation and Design for SARS-CoV-2 (AIRBODS ) project aim is to deliver guidance on the ventilation operation and future design of non-domestic buildings and to quantify the risk of, and reduce the transmission of SARS-CoV-2 in buildings. It is doing this through experimentation, computer simulation and fieldwork supporting the guidance and tools.

Ventilation in Schools - A Review of State Policy Strategies

In January 2023, the Environmental Law Institute (ELI) with funding from the U.S. Environmental Protection Agency (EPA), released the report: "Ventilation in Schools: A Review of State Policy Strategies".
