The energy upgrading of the building stock

Despite efforts, about 73 percent of Italian residential buildings still fall into the least efficient energy classes (E, F, G). It seems clear that there is a need to reduce obstacles along the renovation chain, such as bureaucratic complexity and lack of information.
In addition, the “human factor” related to occupants’ behaviors is crucial to achieving the expected benefits of redevelopment.

1. Reducing Energy Costs.

Energy upgrading involves the implementation of measures to improve the energy efficiency of buildings. These broadly include:

• Thermal Insulation: The installation of thermal insulation systems useful in containing heat loss from the envelope and reduces heat loss through walls, roofs and floors. This results in a significant reduction in heating and cooling costs.
• Efficient Fixtures: Replacing windows and doors with fixtures with low thermal transmittance reduces heat loss and contributes to energy savings.
• Low Consumption Installations: Adopting energy-efficient lighting and technical installations helps to lower the incidence of costs on the utility bill.

These interventions result in direct economic savings for owners, who see decreased energy-related expenses.

2. Increase in the Value of Real Estate

Buildings undergoing energy and architectural upgrades acquire a higher market value than those that have not been renovated. Here’s why:

• Energy Efficiency: Buyers are willing to pay more for properties with low operating costs. An energy-efficient building is attractive to those seeking a long-term solution.
• Energy Certifications: Energy certifications, such as the energy performance certificate (APE), attest to the efficiency of the property. This can positively influence the selling price.
• Sustainability: Environmental awareness is becoming increasingly widespread. Sustainable and environmentally friendly properties are considered a responsible investment.

3. Return on Investment (ROI)

Energy upgrading requires an initial investment, but the benefits in the long run outweigh the costs. ROI (Return on Investment) is manifested through:

• Energy Savings: Lower operating costs translate into ROI over time.
• Increase in Value: The increase in the value of the property represents a gain for the owners.

4. Pure Wood Fiber and Aerogel Insulators

The use of pure wood fiber or aerogel insulation is particularly advantageous in this type of operation and much cheaper than the more widely used synthetic insulators:

• Pure Wood Fiber: This natural material offers a unique, high insulating capacity and helps regulate indoor humidity in buildings.
• Aerogel: Aerogel is an ultralight insulation with exceptional thermal properties. Effective in reducing heat loss it solves large thermal bridges in very small spaces.

In conclusion, energy rehabilitation not only improves the quality of buildings, but is a strategic investment for owners and a step toward a more sustainable society. It contributes to improving the quality of life in cities by reducing air and noise pollution.
This relates to the importance of sustainable urban planning that includes energy rehabilitation as a key element, useful for economic recovery and for combating climate change.
