A building cannot be projected without a judicious preliminary analysis of environmental, social and economical impacts the project will cause on the region it will be inserted.
Cities are complex organisms, and an architectonic project may lead to great transformations in determined areas. This must be taken into consideration.
By inserting a building into a determined region, there will be – depending on the dimensions of the project – increase on the vehicles and people flow, therefore increasing greenhouse gases emissions, noise, water consumption, waste generation, and the necessity of improving infrastructure including restaurants, parking areas, houses, and public transport.
In order to minimize the social impacts caused by an increase in people flow, the architect must consider that the building will preferably be erected in a place surrounded by residential areas. If not possible, there must be efficient public transport available for urban mobility, minimizing or eliminating use of cars and private transport.
Making an analysis of economic impacts, if the project is inserted into an urban emptiness with the intention of enriching the area, this may lead to satisfactory and profitable results for both investors and citizens, once employments are being generated in the area and the empty space is now adding value to the surrounding areas hence raising market value of the enterprise itself.
After all, taking into consideration the environmental, social and economic impacts the insertion of a building causes in an area, and making efforts for these impacts to be positive, there will be perfect equilibrium between large urban impacts, heavy investments, and sustainable growth of a city.
