The Environmental Impact of Housing
Housing construction is one of the biggest culprits in greenhouse gas emissions. A recent United Nations report reveals that this sector is responsible for more than 20% of global emissions. In Spain, the housing stock contributes 14% of greenhouse gas emissions, equivalent to around 29,000 tonnes per year.
Strategies for Sustainable Housing
Given this scenario, it is crucial to explore solutions that reduce environmental impact. In Barcelona, several proposals were discussed in two conferences organized by the Industrial Pact of the Metropolitan Region and the Metropolitan Strategic Plan.
Prioritize Rehabilitation
The rehabilitation of old buildings can be a more sustainable alternative than the construction of new homes. Currently, 55% of homes in Spain are built before 1980, and in Barcelona, this figure rises to 66%. Improving the energy efficiency of these buildings is essential to reduce emissions.
Implement Control Technologies
The incorporation of monitoring systems, such as temperature and energy consumption sensors, can significantly improve the efficiency of use. Angelo Zinni, an expert in renewable energies, highlights that centralizing data is key to optimizing energy consumption in buildings.
Industrialized Construction: A Sustainable Solution
Industrialized construction is becoming a viable alternative for the construction of new homes. This methodology, which involves the manufacture of components in a workshop before their assembly at the final site, allows for reduced construction times and minimized environmental impact.
Sustainable Materials: The Role of the Whip
Wood is a renewable material that can help decarbonize the construction sector. In addition to being an excellent insulator, buildings made of wood maintain internal temperatures better, reducing the need for heating and cooling.
Passive Houses: Design with Vision
Passive houses are designed to minimize energy demand and maximize comfort. However, experts like Raquel Estany point out that the design must take into account the local environment to be truly effective.
Balance between Sustainability and Viability
The ultimate goal is to achieve sustainable housing that is also economically accessible. Sustainability should not compromise the mental health of residents; it is vital to find a balance that allows everyone to access quality housing.
