The quality of filtered clean air provided through ventilation systems that we breathe in is taken for granted, because the air is not visible to the naked eye, whilst the impurities that is carried with is visible upon the important filtration panels catching these impurities requiring quarterly maintenance for working 24/7.
The average person has an air intake of about 3.4 litres of air every minute, therefor the dangers of a poor or polluted air supply are obvious which is why the importance of ventilation maintenance. The risk of fire from build up of grease in kitchen extract ventilation systems and the requirements of building occupiers and legislators leans to an ever more stringent level of ventilation system cleanliness being needed.
The cleanliness of ventilation systems is important for human wellbeing in our working and home environments, lowering energy consumption because of rising utility costs, system maintenance so equipment shelf life is improved so budgets can be spent elsewhere, all improving cleanliness of operations or processes carried out in the ventilated area.
Going forward all domestic properties must start showing 25% improvement on CO2 emissions meaning reducing fuel and energy consumption.
This improvement in Dwelling Emission Rates is a step on the way to zero-carbon footprint for houses. In order for these lowered emissions to be reached means implementing methods of that the property. Heat recovery is a great way to meet these new building regulations. We commonly install heat recovery systems into office and home environments for quality fresh air and keeping the conditioned air in the building whilst filtrating and exhausting the impurities.
By recirculating ventilated air via heat exchangers we can efficiently maintain a clean and comfortable environment. The Department of Energy & climate change is designed to help installers like us keep into speed with renewable heating technologies for providing new innovative solutions for commercial and domestic customers.
Ventilation inspections include a visual inspection of the equipment and its controls, with suggestions for improving the efficiency of the system like improved maintenance, whilst possibly identifying any faults with suggested actions to remedy for restoring its designed efficiency. This in the long run will save you money on rising energy costs!

Practical Recommendations for Buildings Services Operations
Switch air handling units with recirculation to 100% outdoor air so NO recirculation.
Increase Air Supply and Exhaust Ventilation
In buildings with mechanical ventilation systems, extended operation times are recommended. Time ventilation to start at nominal speed at least 2 hours before the building opens to staff and public. Switch to lower speed 2 hours after the building has opened to staff and public. It is not recommended to switch ventilation systems off in any buildings, even those temporarily vacated, but to operate them continuously at reduced speeds.
Demand-Controlled Ventilation Systems
Change CO2 setpoint to lower, 400 ppm value, in order to assure the operation at nominal speed. Keep the ventilation on 24/7. At nights and weekends, do not switch ventilation off, but keep systems running at lower speed.
Temporarily Vacated Buildings
Continue to operate ventilation systems continuously at reduced speed, as this will ensure minimal energy usage but will help to remove virus particles out of the building and from surfaces.
Maximise the supply of outside air as much as reasonably possible while maintaining or increasing the social distancing (min physical distance 2-3 m between persons) among employees in order to foster the ventilation cleaning effect.
In buildings without mechanical ventilation the use of opening windows is recommended, even if this causes thermal discomfort. In buildings with mechanical ventilation, window airing can be used to further boost ventilation, but the balance of air within the building has to be considered to ensure no infiltration of foul air from wash rooms enters other parts of the building when doors are opened to gain access.
