Energy efficiency is one of the main factors valued during the evaluation of a house as it significantly impacts energy consumption. According to the 2022 "Energy in Numbers" report, 40% of Portuguese homes have an energy class below C and 66% below B, on a scale ranging from A+ (very efficient) to F (very inefficient). That is why it is so important to assess the different energy efficiency criteria well before buying a property in Portugal. This is also the case more than ever, and finding an energy efficient property in Portugal is a top priority for buyers, given the rising lost of living and energy crisis.
Portugal has a very aged housing stock, with a capital where 60% of the dwellings were built before the 80s, without being based on the current criteria and needs of energy efficiency, reminds Casavo, which presents 3 points to be considered before moving ahead with the purchase of a home in Portugal.
Pay attention to the materials used
The materials used in construction make the difference between having an energy-efficient home or one with successive losses throughout the processes. There are more effective insulation materials, such as extruded polystyrene, sprayed polyurethane, polyethylene foam or rock wool, which provide protection against cold and damp and prevent thermal bridges, which are responsible for variations in heat flow. Particularly in winter, people's well-being will be at risk if these characteristics are not checked beforehand.
Confirm the energy rating of your equipment and appliances
Electronic equipment has energy efficiency ratings ranging from A to G based on the electricity consumption needed to carry out its functions. So, opting for equipment with higher classes and therefore lower energy consumption will help to significantly reduce monthly expenses when you move into your new home in Portugal.
Check for intelligent management systems (home automation)
Intelligent systems in the various rooms of the house allow you to optimise the working hours of the air-conditioning systems - which regulate the temperature in the property - and monitor energy consumption. These resources make it possible to reduce energy costs without, however, harming the use of the various appliances or people's well-being.
