Let’s bring ventilation in from the cold

Why is there is such antipathy towards putting ventilation at the forefront of our Covid prevention strategy, asks Residential Ventilation Association of Ireland chair and co-founder David McHugh.

Growing use of CO2 monitors to slow Covid spread

While the Irish government is delivering CO2 monitors to schools to help prevent the spread of Covid-19, and some European regions have mandated the use of such monitors in all buildings open to the public, the UK has yet to introduce such measures and has removed the requirement for mask-wearing in schools.

Shooting the moon

The concept of building back better and greener, popular early in the pandemic, is now in danger of being abandoned in the rush to return to ‘normal’ — but we always have the power to shape what normal is, writes Dr Peter Rickaby.

Daikin streamer technology inactivates 99.9% of SARS-CoV-2

New research has confirmed the effectiveness of Daikin’s patented streamer technology, which successfully inactivated more than 99.9 per cent of SARS-CoV-2, the virus which causes Covid-19, after irradiating the virus for three hours.

Viessmann launch ventilation system to tackle covid in schools

Viessmann has launched a new ventilation solution to combat the spread of Covid-19 in schools. The company’s new hybrid ventilation unit, the Vitovent 200-P, provides closed rooms with constant air circulation of filtered air.

The science of filters

How do ventilation filters work, and can they help to protect us against Covid-19? Toby Cambray weighs in on the physics of a subject that is more complex and interesting than you might expect.

Dead air - airborne Covid 19 and poorly ventilated buildings

In the early stages of the Covid-19 crisis, there was little official recognition that airborne transmission was a risk. Has that view changed, and what role will building ventilation play when winter approaches?

NuWave Sensors launches CO2 monitor for schools

NuWave Sensors, developers of smart air quality sensors designed to continuously monitor airborne contaminants in industrial and commercial environments, has unveiled a new carbon dioxide sensor that allows schools to help prevent the spread of Covid-19, while also avoiding energy waste.

Are we the virus?

Taking a temporary detour from his series of columns on the history of sustainable building and renewable energy, Dr Marc Ó Riain takes a look at Covid-19 from the perspective of Gaia theory, and at the relationship between collapsing ecosystems and the emergence of new infectious diseases.

Why shading will be critical in the age of Covid

Over the coming years there will be growing demand for openable windows in our office buildings to help prevent virus transmission — which is why high-quality solar shading will be more important than ever, says Smartlouvre managing director Andrew Cooper.

Experts call for CO2 sensors as tool in Covid fight

CO2 levels in rooms and other enclosed spaces should be used as a proxy for Covid transmission risk, a number of leading experts have said, as the evidence increasingly points towards airborne transmission being a major factor in the spread of the virus.

Are lower land values the silver lining of the crisis?

While the Covid-19 crisis has undoubtedly caused a huge amount of human suffering and economic damage, it has brought some upsides too. Mel Reynolds speculates on how much land prices may fall, and what the positive and negative impacts may be.

Supporting green building’s upskilling

Over the past couple of months, the Irish Green Building Council (IGBC) has been focusing on helping those in the industry to upskill during the lockdown.

New government must support home working - Lidan designs

Roscommon-based modular offsite building manufacturer Lidan Designs has called on the next government to introduce effective financial incentives for companies to provide home office facilities to their employees.

New issue of Passive House Plus free to read

The new issue of Passive House Plus is out now, and to ensure anyone who wants to read the magazine can do so easily during this time of disruption, we are once again making this edition free to read digitally.

Evidence of COVID-19 infections in poorly ventilated spaces

The airborne transmission of COVID-19 may be a risk in enclosed spaces with air recirculation or poor fresh air ventilation, with one study concluding that airborne transmission may have occurred in 48.3% of people in a poorly ventilated office and 34.3% of passengers on an air conditioned bus.

How humanity can save itself from itself

We are in the grip of a global emergency. The science is clear, and thousands of lives have already been lost. The public are demanding firm and bold leadership, but a laissez-faire attitude on the part of western governments has delayed and watered down our response, with calamitous consequences.
