How can passive ventilation with heat recovery improve our health?

The start of week four of our crowdfunding campaign is underway and we’ve been asked a few questions on the health benefits of living or working in a building with good indoor air quality. Whether it is housing stock, commercial premises, schools, colleges or hospitals, good indoor air quality and adequate levels of ventilation is key to the health, performance and well-being of the building occupants.

Outdoor air pollution has long been debated over the years and we have been campaigning to also highlight the dangers of poor indoor air quality and the effects on us from items such as kitchen products, faulty boilers, open fires, fly sprays and air fresheners, all of which can cause poor air quality in our homes, workspaces and schools. It is staggering to think that 99,000 deaths annually in Europe, are caused from indoor air pollution, according to a report issued in February by the Royal College of Physicians (RCP) and the Royal College of Paediatrics and Child Health (RCPCH).

Adequate ventilation in the home and workplace ought to be a key consideration in the attempt to improve the air we breathe inside. If we are to be surrounded by potential pollutants and volatile organic compounds, then appropriate steps need to be taken to minimise the risk. Previous studies have highlighted the dangers of damp and mould in properties for example, and the effect that has on occupants. However, neither the Government, nor the World Health Organization’ can define levels of exposure that are ‘entirely safe’ for the whole population. We strongly believe that good quality air is a human right and needs to be pushed up the political agenda, especially when it comes to commercial and domestic property developers and retrofitters.
As housing stock (new build and retrofit) becomes more energy efficient, even ‘greener’ buildings can be susceptible to trapping humid air in which toxic mould can spread, thus contributing to negative impact on the health and well-being of occupants. Having worked with a number of UK Housing Associations, we have seen first-hand the problems that arise from residing in damp and mouldy accommodation.

Once damp and mould has set in, so will the accompanying health issues that surround them. our passive ventilation with heat recovery system effectively breathes fresh air back into homes without the use of electricity. We have combined the simplicity of passive-stack that boasts the heat recovery performance of a powered mechanical device – but without the associated cost, maintenance and energy use.
We can demonstrate how innovation and smart-thinking has led to some extraordinary impacts on the health of occupants and building performance. We believe that positive action now, will lead to better homes and workplaces in the future.
