Green infrastructure is becoming more and more prevalent in today's world as we face the impacts of climate change. With this trend, one might question if existing buildings and infrastructure can be retroactively converted to green infrastructure or if it is mainly a consideration for new construction.
The answer to this question is not a simple "yes" or "no." In fact, there are many factors to consider when contemplating the retrofitting of existing buildings and infrastructure to green infrastructure standards. Let's explore some of the pros and cons of retrofitting.
Firstly, retrofitting can be a fantastic way to improve the environmental impact of existing buildings and infrastructure. The benefits of green infrastructure are numerous, including reduced energy consumption, lower greenhouse gas emissions, improved water quality, and increased biodiversity. Retrofitting existing buildings and infrastructure to incorporate green infrastructure can help to achieve these benefits without the need for demolition and reconstruction.
There are many examples of retrofitting projects that have successfully converted existing buildings and infrastructure to green infrastructure. For example, a former landfill in Singapore has been transformed into a green park complete with solar panels, rain gardens, and a host of other sustainable features. Similarly, a rundown industrial site in Chicago was transformed into a green space that includes a, biodiverse prairie, and an intricate system of rain gardens to absorb rainwater runoff.
However, retrofitting is not always practical or cost-effective. Existing buildings and infrastructure may not be designed with green infrastructure in mind, making it difficult to retrofit in a way that preserves its intended function. Additionally, retrofitting can be costly and time-consuming, sometimes requiring significant structural modifications to the existing building or infrastructure.
In conclusion, retrofitting existing buildings and infrastructure to green infrastructure standards is possible, but it is not always practical or cost-effective. It is mainly a consideration based on the circumstances of the project and the potential benefits that are achievable. In some cases, retrofitting to green infrastructure standards can be a fantastic way to improve the environmental impact of aging infrastructure. In others, new construction may be the most practical solution. The ultimate goal of green infrastructure is to reduce the impact and improve our relationship with the environment, no matter how we achieve it.
