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 stabilizing 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 240,000 patents, there are 80+ innovation areas that will shape the future of the industry.
Within the emerging innovation stage, atmospheric water harvesting and recycled concrete fillers are disruptive technologies that are in the early stages of application and should be tracked closely. Smart glazing, eco-friendly HVACs, and recycled waste-based cements are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas is wall surface temperature controls, which is now well established in the industry.
Innovation S-curve for environmental sustainability in the construction industry
Smart glazing is a key innovation area in environmental sustainability
Smart glazing, also referred to as switchable or dynamic glazing, denotes a glass or glazing system with adaptive properties based on environmental or user-specific conditions. This innovation enables the glass to modify its transparency, reflection, and thermal characteristics to suit changing conditions, delivering benefits such as energy efficiency, privacy, and enhanced comfort.
This technology encompasses various types, including electrochromic glazing, which alters its tint in response to an electric current, providing control over light and glare. Thermochromic glazing adjusts its tint according to temperature, regulating heat gain and improving thermal comfort. Additionally, photochromic glazing automatically darkens in response to ultraviolet light, serving applications beyond eyewear, such as architectural uses. Smart glazing stands at the forefront of advancements in creating responsive and efficient building environments.
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 280+ companies, spanning technology vendors, established construction companies, and up-and-coming start-ups engaged in the development and application of smart glazing.
Key players in smart glazing – a disruptive innovation in the construction industry
‘Application diversity’ measures the number of applications identified for each patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.
‘Geographic reach’ refers to the number of countries each patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.
