Renovating old buildings is one of the most important steps in creating sustainable communities, many people think that with the progress we need to demolish and remake a lot of fo buildings. Doing that, however, adds significantly to the climate crisis as well as resource crisis because you are losing resources in the demolition process and making new ones. With this in mind the way to eliminate the carbon footprint of the past buildings is to change them into more sustainable and eco-friendly buildings, this eliminates them from the contributors and also poses as a new space to use that didn’t take more materials to make. What goes into renovating is a lot of hard work, going in and looking at soldering buildings (specifically during the era of 1940-1970 because of the use of fossil fuels and related practices). Though it is a hard process and takes a lot of planning and adaptation the fact that it is able to reduce carbon emissions by 15% over a decade of renovations (Oregon) if just 1% of houses and apartments were renovated, make sit worth the effort.
