This online course (~6 hours) covers key topics on how to resume activities, safely operate buildings and specifically use densely occupied indoor spaces during and after the COVID-19 pandemic. The course is based on the REHVA COVID-19 guidance documents and its modules provide basic theoretical knowledge with hands-on information taught by REHVA experts.

The estimated average gap between calculated and actual energy performance of the European building stock is 25% for energy performance and 1.5% for comfort performance (as scored by building occupants). Comprehensive research has shown that poorly commissioned and operated building management systems are often responsible for this gap, generally caused by the lack of appropriate and coherent Quality Management Systems (QMS) for building performance.

Andreas Gyr remembers his first car fondly: a 1982 Ford Escort, which had the gas parts ripped out and replaced with 17 golf cart batteries and an electric motor. “It had about a 15-mile range and it topped out at like 58 miles per hour,” Andreas remembers. “I’d carry an extension cord around and plug it into friends’ wall outlets to make it home.” It might have been inconvenient, but it made him excited about the future. “It was different, it was hopeful, we charged it with solar panels!” he says.

The case is one of the demonstration sites where the technologies developed within the H2020 project BUILDHEAT have been installed. The building is a large multifamily house in a small quarter in the outskirts of Zaragoza. It has 53 dwellings of two main sizes (i.e. 85 m² and 55 m²) distributed in 5 staircases on 4 floors. The building was constructed in 1988, is owned by Zaragoza Vivienda, the social housing Agency of Zaragoza, and is used for sheltered housing.

Energy-efficient upgrades to HVAC systems at schools and other critical buildings can prevent the spread of COVID-19.  Federal funding and tax incentives to make these building upgrades could catalyze a market already projected for growth.  The EU has already embraced building upgrades as part of the European Green Deal framework in its recovery package. What do climate change, COVID-19, and your air conditioner have in common? As it turns out, a lot.

CEN-CE: There will be a huge financial support from the European Commission via the Green Deal. A building renovation roadmap is announced. New challenges are nearly Zero Energy Building (nZEB) and low carbon footprint. What could be in your opinion the contribution of HVAC professionals? Do you think that the HVAC professionals are sufficiently prepared for the new challenges?

The building has been nominated for the BREEAM Energy award 2020 and it is a very ambitious construction in the city centre of Warsaw. The location was originally occupied by a block of flats of 10 floors built in 1960, that was demolished in 2017, in order to enable the construction of the new complex, more in line with the new needs of the Warsaw’s office market.

As facility managers consider their reopening strategies, of course cleaning, PPE, and social distancing policies must be top of mind. But the role of the HVAC system cannot be ignored either. Can improved air filtration and better ventilation actually help reduce the spread of coronavirus? Or does recirculated air — as from air conditioning systems — help spread the virus? Those have been the million dollar questions really since the start of pandemic.

It seems that every week brings the release of a new smart device or system for buildings. Often, the benefit of the new technology is related to energy in order to reduce consumption, trim demand, or cut carbon emissions. Since HVAC and lighting systems are the biggest energy users in buildings, it’s no surprise that there is a wealth of smart technology promising gains in energy performance.
