12 October 2021, Webinar – Smart materials for energy efficient IAQ management

In this webinar, we addressed the opportunities to use novel materials (from advanced functional nano-materials to bio-based building materials) as building components to actively/passively manage the IAQ, for example, through active paint, wallboards, and textiles coated with advanced sorbents or catalysts and quantify their potential, based on the assessment framework developed in the IEA EBC Annex 86 “Energy Efficient Indoor Air Quality Management in Residential Buildings”.


TN 68: Residential Ventilation and Health

Exposures in homes constitute the major part of exposures to airborne pollutants experienced through the human lifetime. They can constitute from 60 to 95% of our total lifetime exposures, of which 30% occurs when we sleep.

ASHRAE Publishes Standard 241, Control of Infectious Aerosols

On July 7th 2023, ASHRAE published its pioneering consensus-based, code enforceable standard, developed to reduce the risk of infectious aerosol transmission in buildings, ASHRAE Standard 241, Control of Infectious Aerosols.


IAQ Aspects of Daycare Centers: A Systematic Review of Exposure to Particular Matter

When an infant is born, he or she begins independently breathing for the first time, meaning that immediately his or her lungs start becoming a principal interface between the outside air and the organism being considerably and continuously influenced by the Indoor Air Quality (IAQ). Daycare centers (DCCs) or early life educational institutions, the first program for the social development of young children (generally aged 0-5 years old), are the most important place besides their home.

Applying NABERS IE to a University Building in the UK

It is no longer sustainable to look at the performance of buildings in isolation of people that use them. This paper examines what is involved in assessing how a building performs for people. The Rose Bowl at Leeds Beckett University is an iconic building designed to BREEAM Excellent. The experience of staff and pupils in classrooms, offices and lecture theatres was proving to be less than excellent.

Applicability of a CO2-based Demand Controlled Energy Recovery Ventilator to a Test Bedroom with Varying Simulated Occupancy

Indoor air quality is a major area of concern in northern housing and could be influenced by ventilation. The required ventilation rate set by North American ventilation standards (ASHRAE 62.2, CSA-F326) is calculated on the basis of fixed floor area and number of bedrooms or people. The heat/energy recovery ventilators (HRV/ERV) on the market offer constant airflows and are selected to meet the required ventilation.

Indoor Environmental Quality Performance Approaches: Trending IAQ to IEQ to COVID-19

The University of Colorado Boulder (CU Boulder) is in Boulder, Colorado USA at 5280 feet above sea level. The campus has approximately 12 million square feet of infrastructure spanning over 100 years of building infrastructure evolution. In response to the COVID-19 pandemic, the University employed a science-based approach with campus researchers including aerosol scientists and campus epidemiologist and industry standards to inform a layered risk management strategy for an on-campus learning experience during the pandemic.

BIM-integrated Indoor Aerosol Modeling Based On Outdoor Particles In Germany

Indoor air quality (IAQ) plays an intrinsic role in occupant comfort, and should be evaluated as a key building performance indicator of early design phases. However, IAQ is very complex due to a plethora of chemical compounds in the indoor air and also depends on the activities in the building. Therefore, IAQ assessment is often not comprehensively considered, or applied only during late project phases. This study reviewed how Building Information Modeling (BIM) could be applied for IAQ performance analysis, to provide a more holistic design process.

Design of a Ventilation System to Improve IAQ and Thermal Comfort in a Textile Factory

Indoor environment quality has been researched extensively, with many countries adopting regulations to ensure that building occupants enjoy healthy working environments. In many small island developing states (SIDS), such as Mauritius, the population benefits from perfect weather conditions, but building design considerations often under-estimate the effects of outdoor weather conditions, heat and pollutant emission, illumination and noise, which worsen indoor environment.

Indoor Conditions in Educational Buildings: the Case of Bolzano Schools

Indoor environmental quality in educational buildings is recognized as a crucial aspect for the achievement of the learning outcomes for students. Nevertheless, indoor school conditions are often found unsatisfactory in several European countries, including Italy, especially as regards indoor air quality IAQ. For instance, taking CO2 concentration as IAQ indicator, the threshold of 1000 ppm is often overcome, suggesting insufficient ventilation rates.
