Winter is just around the corner, and it’s time to prepare for it in the most comfortable way possible, both outside and inside your home. Just as we stock up on coats and warm clothing for the cold, homes also need to be prepared as temperatures begin to plummet.

While new buildings are already designed to withstand harsh weather conditions, most homes in Spain unfortunately fall short in this regard.

In fact, according to the Report on the Status of Energy Certification of Buildings by the Ministry for Ecological Transition and the Demographic Challenge, over 80% of existing properties in Spain have an energy rating between D and F—the lowest categories.

What Does This Mean?

Homes with low energy ratings consume a lot of energy to stay warm in winter and cool in summer. They are highly vulnerable to temperature fluctuations, requiring significant electricity usage to maintain comfort. The result? High electricity or gas bills and a substantial release of greenhouse gases into the atmosphere.

The goal is clear: to maintain a comfortable indoor temperature year-round without excessive energy consumption. The good news? Even older homes can be renovated to achieve this, and subsidies are available to help foot the bill.

Benefits of Renovating Your Home (for the Environment Too)

The situation in Spain is pressing. According to the Green Building Council, the pace of energy-efficient building renovations needs to increase twelvefold to meet the European Union’s 2050 decarbonisation targets. This makes it essential for not only industry stakeholders but also homeowners and their associations to take action. Property owners hold the key to driving improvements in their homes and residential buildings.

Here are the main benefits of energy-efficient renovations:

• Economic Savings
  The most obvious advantage for residents is financial. Renovating your home can result in significant savings on heating and air conditioning costs. According to the Organization of Consumers and Users (OCU), households with an energy rating of E or lower could save up to €1,000 annually on climate control expenses.
• Renovation Grants
  As a priority in European public policies, Next Generation funds include grants and subsidies for building and home renovations. According to the Ministry of Housing and Urban Agenda, these can cover 40% to 80% of the project costs. Eligible improvements include better facade and roof insulation, conservation and accessibility upgrades, window replacements and modernising heating or air conditioning systems.
• Increased Property Value
  Renovating your home enhances its market value, which can be crucial if you plan to sell or mortgage the property.
• Reduced Emissions into the Environment
  Lower energy consumption translates into fewer emissions of greenhouse gases, curbing the depletion of finite fossil fuel resources.
• Health Benefits
  Energy-efficient homes can positively impact health by maintaining a stable indoor climate, avoiding unnecessary exposure to cold or heat. Additionally, modern climate systems can improve air quality, reducing respiratory issues.
• Job Creation
  Renovations also have a social impact, creating jobs and boosting economic activity in the construction sector.

Steps to Renovate Your Home

Several measures can be implemented to improve home climate efficiency. Here are the key ones:

1. Install Effective Thermal Insulation Systems
   External Thermal Insulation Systems (ETICS) are the most effective solutions. These are systems applied to building exteriors, acting as a thermal envelope to protect interiors from both heat and cold. This method outperforms internal insulation in terms of efficiency.
2. Upgrade to High-Efficiency Windows
   Replacing old windows with double- or triple-glazed models is essential for better insulation. Casement or tilt-and-turn windows are preferable to sliding ones due to their superior airtightness. Additionally, solar control glass can reduce sunlight glare during summer.
3. Replace Outdated Boilers and Furnaces
   Replacing old boilers and furnaces is crucial, as they are inefficient and emit harmful gases. Heat pumps are a more effective alternative. Radiant floor heating or smart radiators can also be installed for better energy efficiency.
4. Embrace Renewable Energy
   Solar panels and even geothermal energy systems are excellent options for promoting self-sufficiency, especially in sunny regions of Spain.
5. Switch to Efficient Lighting
   Replace traditional bulbs with LED ones and consider installing motion sensors to reduce energy consumption.
6. Incorporate Mechanical Ventilation Systems
   Mechanical ventilation systems can improve indoor air quality, adding to overall comfort and health benefits.

By undertaking these measures, you can enjoy a more comfortable winter and make significant energy savings while harnessing all these advantages.
