In 1854, a few years after ventilating the fiasco of the permanent parliament building Reid moved to the United States. Before that, he however developed and finalized a at the time a high-tech complete ventilation system that worked in nearly 130 years, and that of many today is considered the first of its kind. In St. George’s Hall, a large exhibition hall with combined operations in Liverpool, were installed four steam engine driven by variable speed fans on each of three meters in diameter. These could support the building up to 5,000 visitors with variable air flow rate equivalent to 5 l/s per person, which is broadly in line with current recommendations. After filtration, heating/cooling and humidification even if desired, distributed air along the walls through thousands of small holes near the floor. The indoor climate was controlled and regulated continuously in every detail, which required a small army of employees.

History of ventilation: Mechanical supply and extract air ventilation introduced into apartment blocks in 1960s!
Even if mechanical extract air systems were the most common forms of ventilation solutions in housing in the 1960s, apartment blocks were sometimes built with supply and extract air solutions. However, in contrast to non-residential…

History of ventilation: Extract air ventilation in detached houses, especially in northern Europe in 1970s!
Buildings started to be designed with increasingly more air-tight envelopes. To ensure the desired ventilation flows all year round, mechanical extract ventilation systems, and even supply and extract systems, also began to be installed in…

History of ventilation: Extract air heat pumps installed in detached houses, especially in Scandinavia in 1980s!
The oil crisis had serious repercussions among house owners. Extract air heat pumps became more popular as everyone strived to save energy. Today, this solution is also quite common in apartment blocks.
