ISIAQ's New Journal: Indoor Environments

Elsevier and the International Society of Indoor Air Quality and Climate (ISIAQ) are proud to introduce Indoor Environments, a new international, multi-disciplinary research journal dedicated to advancing the field of indoor environmental sciences. This journal will serve as a vital platform for researchers, scholars, and professionals interested in all aspects of indoor environments, including health, comfort, and climate change adaptation and mitigation.


Indoor Air, Ventilation and comfoRt in Irish Domestic dwellings post DEep Energy reNovations-ARDEN

Deep Energy renovation (DER) adopts a whole building approach and achieves much larger energy savings than shallow energy renovations that typically only included a small number (one or two) of upgrade measures. DER includes the installation of high levels of insulation, uses renewable energy technologies and minimises uncontrolled air leakage by achieving air permeability levels no greater than 5 m3/h.m2 to achieve building energy ratings (BER) of at least A3.

Indoor Temperature and CO2 in Educational Buildings during a Pandemic Winter in Spain

Schools had covered special attention in the last year, due to their importance to organize daily work as well as since most of the children were still not vaccinated. Under this circumstance, the importance of air renewal to reduce the probability of COVID-19 contagion inside buildings was highlighted. 

Design and Indoor Air Quality in Kindergartens in Italy

The serious social and health crisis faced as a result of the spread of SARS-Cov 2 has highlighted the weaknesses of human beings but has mainly highlighted the inadequate static response of existing buildings; all those confined spaces characterised by the simultaneous presence of a large number of people, such as classrooms, have shown, over the past two years, how unhealthy are because of the high possibility of contraction of the virus inside them.

RENOVAIR : a study of the evolution of airtightness, ventilation, comfort and indoor air quality in energy efficient refurbishment social housing operations in France

Many European programs offer eco-conditioned financial aid to support public policies for the decarbonization of buildings. This is the case, for example, of the 2017-2022 ERDF Operational Program, which financially assists social project management for energy efficient refurbishment operations of its building stock. The eligibility conditions for financial aids concern the energy consumption, the thermal insulation performance of the building envelope and the energy efficiency of heating, cooling and ventilation systems.

Challenges in transition towards a sustainable built environment from a European and National perspective

By 2050, the entire built environment must be climate neutral. Before that final date, we have to find an alternative to the use of fossil energy in the built environment. The switch to a climate neutral built environment requires an integrated approach, focusing on switching to alternative, non-fossil fuels and on reducing the energy demand by taking energy efficiency measures.

The transition to climate neutrality has a large impact on the job of building and HVAC designers, manufacturers, installers, investors, etc. Renovating our building stock to make it more energy efficient is a huge task. Both research and practice prove that users have an important impact on this performance. Human-building interactions, like window opening, thermostat and solar shading usage, affect the performance of the building and HVAC systems.


22-25 May, 2022, Conference, Rotterdam – CLIMA 2022

The REHVA World Congress CLIMA is the leading international scientific congress in the field of heating, ventilation and air conditioning (HVAC).

CLIMA 2022 takes place 22nd – 25th of May 2022 both in Ahoy Rotterdam as well as online. Don’t miss out on this great event and book your tickets, either for the live or online experience.


Comfort at hospital reception desks

For several years indoor comfort is measured in halls of hospitals by architecture students from the Delft University of Technology. Questionnaires and interviews have shows that patients and visitors have very few complaints about the indoor comfort in hospital halls.  

The new air tightness class in ductwork - Aeroseal technology to seal leakages in new/retrofit ductwork and duct components - the foundation for highest energy efficiency in ventilation systems

Aeroseal technology utilizes air laden with fine aerosol particles (2-20 μm) to pressurize a duct system, resulting in deposition of those particles at the leaks within that duct system. By reducing leakages of duct systems by 90% in average Aeroseal sealing technology allows reducing leakages to a standard better as air tightness class D or ATC 1 for a complete system. Aeroseal technology can be applied in new constructions as well as in existing systems to improve energy efficiency, cleanliness of ventilation systems, IAQ and comfort.
