If you don't know the exact area, you can estimate by measuring the length and width of each room and multiplying them together. Add these numbers for all rooms to get a rough total. Alternatively, check your property documents or energy certificate, which often include this information.
You can find this information in your property's "Caderneta Predial" (Property Tax Document) available from the Finanças Portal. If you don't have access to this, check your deed of sale or consult your local municipality's urban planning department. The construction year is crucial for determining the most suitable insulation method.
In Portugal, the energy efficiency certificate (Certificado Energético) is mandatory for properties being sold or rented. If you don't have one, you can obtain it from a qualified energy assessor. The ADENE (Agência para a Energia) website provides a list of certified assessors and more information about the process.
In most cases, interior insulation doesn't require special permits. However, for external insulation or significant alterations, you may need approval from your local câmara municipal (city hall). Our team of experts, including a civil engineer, can guide you through any necessary legal requirements during the assessment process.
The main source for energy efficiency subsidies in Portugal is the Fundo Ambiental (Environmental Fund). Check their website for current programs like "Edifícios Mais Sustentáveis" (More Sustainable Buildings). Additionally, some municipalities offer local incentives. During our free assessment, we can provide up-to-date information on subsidies you might be eligible for.
