Energy Certification – How to Improve Your Property’s Performance?

Energy Certification is mandatory in Portugal when selling or renting a property. However, it goes far beyond a legal requirement – it can increase your property’s value and reduce monthly energy costs.

Why improve your energy rating?
- Higher property value: properties with better ratings are more attractive on the market.
- Lower consumption: improves thermal comfort and reduces monthly energy bills.
- Sustainability: contributes to national and European climate targets.

Measures to improve energy certification (ADENE)

- Thermal insulation
Reinforce exterior walls, roofs, and floors to prevent heat loss in winter and excessive heat gain in summer.

- Window replacement
Install double-glazed windows with thermal break for greater efficiency.

- Efficient heating and cooling systems
Use equipment with high energy efficiency (class A or above).

- Solar panels (thermal or photovoltaic)
Produce renewable energy for self-consumption or water heating.

- LED lighting
A simple, low-cost solution with immediate impact on the property’s energy efficiency.
