For example, a public sector pilot carried out in schools and homes in New York, Milan and Copenhagen introduced a methodology and toolkit to enable cities to quantify the benefits from deep retrofit projects. Trials and examples such as this will support Government in motivating people to change their thinking and support regional Governments in making the case for funding or to crowd in private investment.
CASE STUDY: Benefits of Deep Retrofits C40cities, Burohappold Engineering and Rockwool undertook a study to provide cities with a unique toolkit to estimate the multiple benefits of retrofitting a portfolio of buildings as well as an entire city-wide programme366. This toolkit was piloted on specific retrofit projects in three C40 cities: | |||
