Retrofitting a house typically refers to making modifications or upgrades to an existing building to improve its energy efficiency, safety, or functionality.
The specific changes made during a retrofit will depend on the goals of the project and the condition of the building, but some common examples of retrofitting include:
Insulating walls, floors, and ceilings to reduce energy consumption and lower heating and cooling costs. Upgrading windows and doors to improve insulation and reduce drafts.
Installing energy-efficient lighting, appliances, and HVAC systems to reduce energy consumption.
Adding earthquake-resistant features to improve the structural stability of the building.
Installing safety measures such as smoke detectors, carbon monoxide detectors, and fire sprinkler systems.
Overall, retrofitting can improve the comfort, safety, and sustainability of a house while also reducing energy costs and environmental impact.
