Buildings are responsible for more than 30% of Greenhouse Gas (GHG) emissions and homes in particular represent 20% of energy consumption. For this reason, it is important to take measures to promote energy rehabilitation to improve its sustainability and reduce its energy consumption and emissions.
The energy rehabilitation of a building (retrofitting) consists of implementing a series of measures and installations with the aim of reducing its energy consumption (solar panels, improving insulation, etc.) and even achieving self-sufficiency. In addition, these measures provide health benefits to the inhabitants of the home.
“Energy rehabilitation allows, in addition to satisfying the recommendations of the IRAM Standards, to improve the level of energy labeling with thermally comfortable environments,” comments Silvina Plante, member of the group of institutions for the energy labeling of homes.
The energy rehabilitation of a home step by step
If you want to make a more sustainable home or building, you can follow certain steps.you are key:
• Step 1: Label the home
The labeling carried out under IRAM 11900 is a procedure that is carried out to know the energy situation of the building. As a result, an energy rating for the home is obtained, that is, its label. The highest energy rating, that is, the most efficient label, is A; and G is the letter for those less efficient homes.
“For a home to achieve better use of energy and thus reduce its consumption, it is key to first quantify its energy requirement. For this there is what is known as the Energy Efficiency Label.
“For a home to achieve better use of energy and thus reduce its consumption, it is key to first quantify its energy requirement. For this there is what is known as the Energy Efficiency Label, a document that shows the energy requirement that the property requires to satisfy the needs of heating, cooling, domestic water heating and lighting, according to how it was built and the facilities with which it is installed. that counts and its location, ensuring interior hygrothermal comfort,” highlights Pedrazzi.
• Step 2: Take action on the homes
After labeling, we analyze where the sources that cause low energy efficiency are. For example, poor or lack of thermal insulation, air leaks, inefficient openings, among others. The measures to take to improve the consumption of a home can be:
-Improve thermal insulation acting on the envelope – roof, walls and floors – of the home
-Avoid air leaks to avoid losing energy, changing the windows for efficient ones, for example.
-Install a correct ventilation system through mechanical ventilation ducts and devices such as heat recoverers, which reduces the heat demand of a building
-Maximize natural light and use smart lighting devices and systems, for example, lights that turn on and off when presence is detected.
–Change the use of conventional energy for clean energy and renewable, for example, solar.
• Step 3: Efficient installations
Another aspect to take into account is improve the efficiency of air conditioning or lighting systemsamong others, for those that consume less energy to better take advantage of the renewable energies that are incorporated, such as solar energy. Additionally, automation and control systems can be installed to avoid unnecessary energy costs, such as lights that are activated by a sensor, or that regulate the use of air conditioning devices, for example.
