The fight against climate change is vital in the real estate sector and digital transformation of the sector is key to minimizing the environmental impact. Kokono is a digital solution that reduces CO2 emissions and energy consumption in the real estate sector. Kokono has developed software that analyzes the energy usage of a property or a portfolio of properties and determines the optimal actions for their rehabilitation. Its algorithm takes into account factors such as the impact on emissions, energy consumption, rehabilitation costs, subsidies that the owner can access, and the economic revaluation of the asset or portfolio of assets once rehabilitated.
