In addition to being an alternative to the lack of well-located land available in cities, retrofitting is one of the ways to contribute to the revitalization of degraded areas that suffer from the effects of time, as is the case in the center of São Paulo.
Adriana Marques, Project Coordinator, highlights that corporations, in turn, are not left behind: ''energy efficiency modernizations can reduce operational costs, especially in older buildings, as well as help attract tenants and gain an advantage in a real estate market as competitive as that of large capitals'', he says.
The conversion of obsolete and underused commercial buildings into residential ones, as we have frequently seen, is also an alternative that combines sustainability, since the infrastructure and maximum materials are reused.
The beauty of retrofitting lies precisely in preserving the essence of the building and making it much more functional and efficient, both in relation to the use of materials, resources and technologies. Not to mention the reduction of carbon emissions related to the demolition and construction of a new structure and foundation, in particular, the large amount emitted by the cement and steel used in construction: ''increasing the useful life of buildings is a great solution for the targets for reducing greenhouse gas emissions and assisting with climate commitments'', comments Adriana.
Old buildings have also sought operation and maintenance sustainability certification processes to guide the necessary adjustments, reduce their environmental impacts and operating costs, in addition to showing the market this positioning of the enterprise and making it more competitive in relation to new buildings. often in its surroundings.
From a cultural point of view, the retrofit technique helps to preserve the historical and architectural heritage of cities, as the idea is to maintain the architectural style of buildings, many of which were built many decades ago, and which carry years of history, especially in large cities, where modern buildings coexist with temples, palaces, museums and forts from centuries ago. These constructions reveal much of what our society was and is.
Harmony between past and present
Inclusion of elevators, modernization of the air conditioning system, renovation of facades and development of common and leisure areas such as coworking, gym and laundry are some points considered in a retrofit.
Especially when talking about converting a commercial building into a residential one, structural changes are often necessary, but the objective of the technique is to keep interferences, especially aesthetic ones, to the minimum possible.
It is important to consider that we spend an average of 90% of our lives indoors, according to the “National Human Activity Pattern Survey”, carried out by Berkeley Lab Energy, an American institution that researches and develops energy technologies and the reduction of environmental impacts.
Therefore, the responsibility of developers, investors, design and construction teams to create or adapt internal environments into healthy environments and thus promote the well-being of users is fundamental, even more so with the experience we have acquired after the COVID-19 pandemic in relation to to well-ventilated environments that promote well-being and decompression.
Studies and laws related to the quality of the internal environment, for example, have improved over the years and, sometimes, the legislation at the time of construction of these buildings did not require items in these aspects, which can cause a lot of discomfort in users, creating the syndrome of the sick building and contribute to the vacancy of the project.
Centro Requalifica Program
Much of this growing retrofit movement in the city of São Paulo in recent years was driven by the Requalifica Centro Program (17.577/21), created in 2021 and which establishes tax and building incentives to encourage the retrofit of old buildings in the central region of the city.
According to the capital's city hall, the objective is to stimulate a greater supply of housing properties to densify the center and restore its vocation as an attractive environment for investment.
