For instance,

  • On May 17, 2021, the Biden Administration accelerated efforts to attend to the goal of modernizing and upgrading the nation’s residential and commercial buildings to be affordable, resilient, accessible, energy-efficient, and electrified. The administration promises to build, rehabilitate, and retrofit more than 2 million houses across the U.S.

  • On August 13, 2021, the U.S. Department of Energy (DOE) awarded USD 82.6 million in funding toward 44 projects that will lower energy bills. These project help to meet goal of net-zero carbon emissions by 2050 by investing in new energy-efficient building technologies and construction practices. New Jersey Institute of Technology will design, prototype, install, test, and evaluate a high-performance residential wall retrofit that can achieve estimated heating and cooling energy savings of 30% or more.

Government Regulations and Frameworks To Implement Energy Improvement Projects To Propel Growth

Retrofitting systems are typically used in commercial, residential buildings to save around 10-40% of the energy use. Due to this, the use of energy retrofits systems is complemented with various government regulations, financial models, and policy frameworks to cover more buildings with energy retrofit systems to improve the energy performance of the buildings.

For example, the Mayor’s Energy of Londoner's program has designed a retrofit accelerator for homes and buildings to pace up the cutting carbon emissions and achieving zero carbon by 2030. Moreover, the European Regional Development Fund bagged the program, which also helps tackle the climate emergency and reduce energy bills through insulation and low carbon heat and power solutions.

Other notable example includes the implementation of strict legislation by the Netherlands government to make it mandatory for office buildings to meet the buildings' performance level C by 2023 and performance level A by 2030. Almost 15,000 buildings/houses are currently needed to complete the 2023 requirements. EU Emissions Trading provides funds or revenue to leverage private investments in building renovation, which is anticipated to improve the market landscape for energy retrofit systems.


Lack of Information and Insufficient Infrastructure to Hinder Market Growth

As per the European Union (EU), the residential sector accounts for almost 27.2% of energy consumption and 24% of CO2 emission. The European Union has established energy policy and long-term investment strategies to renovate the residential stack by 2050 completely. However, achieving efficient energy levels is not a straightforward task in the residential sector. The existing gap in energy efficiency is caused due to the irrational behavioral habits of residential consumers. Various studies have investigated that the gap of energy efficiency between investment opportunities and actual implementation hinders the energy retrofit systems market growth. Also, behavioral explanations, model & measurements error, and lack of information about the benefits and various possibilities of the efficient use of energy hinder the market growth. Additionally, other factors such as change in structures also create challenges for the energy retrofit market. The use of energy retrofits systems might harm heritage and archaeological assets, which the usage of unproven methods can cause, technologies or instruments.
