Retrofitting is the process of upgrading existing buildings to improve energy efficiency, comfort, and sustainability. It involves making strategic improvements to insulation, ventilation, heating and cooling systems, and overall energy usage. By retrofitting your home, you can reduce energy consumption, lower utility bills, and create a more comfortable living environment for you and your family. This can include installing energy-efficient windows and doors, upgrading insulation, sealing air leaks, installing more efficient heating and cooling systems such as heat pumps, and integrating renewable energy sources like solar panels. Retrofitting is an important strategy for reducing carbon emissions and improving the sustainability of buildings, particularly older ones that may not meet modern energy efficiency standards.
