However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilising and reaching maturity.

Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.

80+ innovations will shape the construction industry

According to GlobalData’s Technology Foresights, which plots the S-curve for the construction industry using innovation intensity models built on over 179,000 patents, there are 80+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, green roofing is a disruptive technology that is in the early stages of application and should be tracked closely. HAWT wind turbines, environmental barrier coatings, and vacuum-insulated glazing are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are hybrid electric heavy machinery and energy-efficient HVAC system, which are now well established in the industry.

Innovation S-curve for environmental sustainability in the construction industry

Energy-efficient HVAC system is a key innovation area in environmental sustainability

A heating, ventilation and air conditioning system, or HVAC, is a means to control the ambient conditions within an enclosed space. Given their substantial energy requirements during warmer periods, HVAC systems contribute significantly to global warming, driving the need to maximise their energy efficiency. Efficient HVAC systems can be achieved through both design and use, taking advantage of methods such as demand-controlled ventilation or designs that utilise waste heat to warm air or natural moisture to cool air.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 150+ companies, spanning technology vendors, established construction companies, and up-and-coming start-ups engaged in the development and application of Energy-efficient HVAC system.

Key players in energy-efficient HVAC system – a disruptive innovation in the construction industry

‘Application diversity’ measures the number of different applications identified for each relevant patent and broadly splits companies into either ‘niche’ or ‘diversified’ innovators.

‘Geographic reach’ refers to the number of different countries each relevant patent is registered in and reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.
