Introduction The building sector is responsible for consuming approximately 40% of final energy in Europe. However, over 50% of this consumption can be reduced through energy efficiency measures, which may represent an annual emission reduction of 400 million tonnes of CO 2. (in www.adene.pt) 10
Introduction The importance of the performance envelope of a building Losses and heat gains in the envelope of a single family house Roofing: 24% Facade opaque: 31% Facade translucent: 36% Calor The thermal insulation of the facade of a building is a very important component in their energy performance 11

Regulamentation Energy consumption in buildings The Portuguese State published in compliance with the European Directive (2002/91/EC) on the energy performance of buildings, the Decree-Law 118/2013 establishing the Energy Certification of Buildings (SCE) and laying the foundations of two new regulations: Regulamento de Desempenho Energético dos Edifícios de Habitação (REH) (regulado pelas Portarias n.º 349-B e C/2013) Regulamento de Desempenho Energético dos Edifícios de Comércio e Serviços (RECS) (Portarias n.º 349-D e 353-A/2013) referring to a series of dispatches from the General Directorate for Energy and Geology, which calculation methodologies, to adopt specific rules and also data, zoning and climatic parameters are set 18
Regulamentation Climatic zones REH/RECS Climatic zones - Winter Climatic zones - Summer 19
Thermal bridges Regulamentation In the areas of thermal bridge flat, corresponding to heterogeneities in the current opaque zone surrounding (pillars, beams, blind boxes, etc..), The heat transfer coefficient U calculated in the direction perpendicular to the plane of the same may not have a value higher than double calculated for the current zone, and can not exceed certain maximum values set according to the type of element (vertical or horizontal, engaging exterior or interior) and the winter climate zone. U 1 U 1 U 2 U 2 U 2 2 x U 1 U 3 U 3 2 x U 1 20

Advantages Drastic reduction of thermal bridges, allowing continuous insulation uninterrupted areas of the structure 28
Advantages Decreased risk of condensation on the inner face of the front wall 29
Advantages Consideration of the mass of the facade to assess the class of thermal inertia of the building wall 30
Advantages Protection against the wall frame and large variations in temperature 31
Advantages Increase in floor area within the living space 32
Advantages Easy and effective use in the rehabilitation of facades: rehab is done without the need to vacate the building 33
