Filters & air cleaning
Introducing the new Fujitsu Webstore
Taking the approach of splitting each area into zones will allow each issue affecting IAQ in these areas to be treated individually. For example, if new equipment is needed to improve IAQ, each area may benefit from different solutions – meaning it’s almost certain that each zone will require a unique approach to measurement and long-term maintenance. Once a building review has been conducted, it can be useful to categorise actions by their level of urgency. This will make it possible to prioritise any areas that require urgent attention, starting with spaces that don’t have a ventilation system with modern filtration. This will also allow for less-urgent actions to be identified, helping to inform the creation of medium and long- term plans for improvement, as well as the overall maintenance of areas with good air quality. Investing in the right technology Every building is different, which means that no single piece of technology or solution will ensure the best level of indoor air quality across them all. Luckily, there are multiple types of ventilation and air filtration systems available, all designed for different needs and requirements. The first is simply natural ventilation – which supplies and removes air from a building without any mechanical equipment, and could be as straightforward as opening the window. For spaces where there is no access to natural ventilation, mechanical
ventilation and heat recovery systems (MVHR) can make use of fans and other equipment to move air in and out of a building, while using the energy from warm, extracted air to pre-heat air entering the building. Another option is air conditioning, which has the primary role of improving
comfort conditions for occupants. While ventilation must be at the heart of IAQ, air conditioning can help to ensure that indoor temperatures are kept comfortable throughout the year, while also protecting indoor air quality by reducing the likelihood of mould contamination. Finally, filtration and air conditioning should also be considered, as it is one of the most important factors in achieving good indoor air quality. Filters in a ventilation system remove unwanted contaminants from the air as it enters the building - with its growing importance being reflected in a convergence of standards and guidelines helping to identify the best filters for a building’s requirements over the past few years. While the pandemic has highlighted the importance of better ventilation in making buildings more infection resilient, we must ensure that the provision of good IAQ continues to be a top priority in our schools, offices and public buildings. Going forwards, it is essential that building owners and managers take the time to devise and implement a strong strategy for achieving and maintaining good IAQ, and oversee its effective delivery in the months and years ahead.
