Les Cahiers de l'Anah — July 2016 "This is clearly the preferred choice for renovation projects, compared to traditional construction methods," confirms Joy Gai. "And it's also a very good way to affirm (and showcase) the sustainability of the building." Renovating inWesterncountries–what arethebenefits? Apart from the obvious interests in terms of decarbonization and the provision of quality housing for an ever-increasing population in urban areas, the implementation of proactive renovation policies brings many benefits. First of all, they have a key role in revitalizing the local economy, by using land that is sometimes under or misused, but also by attracting investors who will create local jobs. It is estimated that the implementation of the New York City Climate Mobilization Act (United States), which involves the renovation of 50,000 large buildings, could create an €18 billion market by 2030. This would result in the creation of 141,000 new jobs in the New York metropolitan area over the next decade – far more than the initial estimate of 26,700 jobs7. Another advantage is the benefits of renovation to public health. According to a report by Copenhagen Economics, commissioned by Renovate Europe, the health benefits of an ambitious energy renovation plan in the European Union could reach €88 billion8. For their part, theWorld Health Organization and the OECD estimate that every year 120,000 Europeans die prematurely simply due to poor indoor air quality, which represents an annual cost of €260 billion9. In Toronto, a study found that bringing residential buildings into compliance with the minimum building code requirements could save the city up to $2.3 billion a year in healthcare costs10. Ultimately, renovating is about restoring the luster to buildings or historic areas sometimes abandoned by populations. This is what the municipality of Rodez in the south of France has done. Until a few years ago, the city center had a number of problems: old, dilapidated buildings, precarious populations, vacant housing and shops. The architectural revitalization (the renovation of more than 600 dwellings and the enhancement of historic facades) has brought the old town back to life. "The people of Rodez are returning to the city center for walks, shopping and even to live there. We have taken action at various levels (city, community and region) and all in the same direction," explained Christian Teyssèdre, Mayor of Rodez and President of Rodez Agglomération to the journal Cahiers de l'Anah11. It is understood that, inWestern countries, the ‘carbon balance’ but also the economic and cultural balance are decisively leaning toward a massive renovation campaign to ensure sustainable building in our cities. 35 CONSTRUCTING A SUSTAINABLE FUTURE
