Assessment of the Retrofit Strategies on Thermal Insulation Applied in Buildings Located on the Southern Border of the EU: The Case of the Canary Islands

Nowadays, a large amount of the total primary energy is consumed by buildings, accounting for about 40% demand. Aligned with EU objectives and strategies to reduce demand, cooling heating are stated as most consuming processes building envelope plays an important role consumption. In this work, demand related in typical has been evaluated, which simulated 35 cities located different climatic zones, using DesignBuilder v.6.1.7.007 software. Although increase insulation replacement windows lead reduction case Santa Cruz de Tenerife Las Palmas Gran Canaria without insulation, demands lower than 1.7 kWh/m2/year 5 kWh/m2/year, respectively, these results indicate that saving strategies, driven policies economic support, based on renovation improvement thermal envelope, not appropriate due need additional load maintain comfort within regulatory limits.
