US Ventilation 2020
美國的通風設備市場，儘管落後於擁有先進相關法律法規的加拿大，不過，今後預計順利成長。住宅 (獨門住宅，多用戶住宅) 和商業設施的雙方，空氣調節機 (AHU) 和一體型的能源回收型通風設備 (ERV)預計越來越普及。
These reports provide an in-depth analysis of the USA ventilation market as well as an examination of key challenges facing the industry. They examine technology innovations that will influence the future direction of the market, and also feature detailed profiles of key industry players. The market coverage includes core ventilation technologies (mechanical 'forced' ventilation systems) for residential and commercial applications. The North American market for mechanical ventilation products, like the European market, is largely driven by legislation and construction activity with market growth highly correlated to tightening regulations and increased housing completions. This is clearly illustrated by the discrepancy between the Canadian and the US ventilation markets. Canada, where ventilation has been part of the National Building Code for around 40 years, is believed to be years ahead of the US in terms of market maturity.
Uptake of ventilation products in the US varies on a state-by-state basis with market growth strongest in the states that have implemented legislation either recommending the use of balanced ventilation products or by stipulating the use of increased insulation and tighter building envelopes in new construction. Both North American markets are currently dominated by unitary fans, although centralised systems with heat recovery continue to gain in popularity in both single family and multifamily housing, especially in Canada. Air handling units with bolt on commercial ERVs are mainly used in commercial applications and multifamily housing. The outlook for the North American ventilation market is positive, with sales in Canada and the US together anticipated to grow by 2024. As centralised heat recovery units increase in popularity, unitary fan sales will struggle to maintain their current sales levels but will remain the bulk of the market and drive the majority of volume sales growth. The total market value is driven by the non residential products; it will also continue to increase as the equipment is becoming more sophisticated and expensive and demand is also going up.
