Hotel renovations today transcend mere improvements in guest comfort or alignment with prevailing design trends. A major demand currently facing the industry is the need to respond to the growing wave of environmental awareness and embrace sustainable development objectives. The requirement to address sustainability is driven by a growing social awareness of environmental issues. Guests and stakeholders are increasingly advocating for sustainably certified structures, achieved through eco-friendly installations and innovative solutions, such as green roofs, eco-friendly materials, and innovative facades. This sustainability-driven shift benefits the environment and promises long-term savings in water and energy costs for hotels. Specifically in the case of hotels, improving the efficiency of hot water equipment can make a large difference in hotel management, as this generally represents a huge expense and waste of energy.
