WHY EIFS / ETICS? POSSIBILITIES FOR ENERGY SAVING: EIFS MAIN LEVER

PERFORMANCE REQUIREMENTS AND STANDARDS FOR EIFS Mohammed Sanaobar, L-B-E-T/TC Dubai, 25-06-2008, Slide 3

WHY EIFS? EIFS has proved to have a superior energy efficiency by reducing heat transmission by approx 50% Improved energy efficiency helps to reduce harmful emissions typically associated with energy production such as CO2 emissions and other by-products Design Flexibility and Decorative Finishing Superior EIFS energy efficiency reduces required air conditioning equipment capacity and limits the physical effects of temperature fluctuations hence reducing structural stress EIFS can be applied to new and existing structures. EIFS is the ONLY solution for insulating existing buildingsPERFORMANCE REQUIREMENTS AND STANDARDS FOR EIFS Mohammed Sanaobar, L-B-E-T/TC Dubai, 25-06-2008, Slide 4

CRITICAL FACTORS THERMAL BRIDGES

source ETAG 004 Edition 2004 PERFORMANCE REQUIREMENTS AND STANDARDS FOR EIFS Mohammed Sanaobar, L-B-E-T/TC Dubai, 25-06-2008, Slide 22

CRITICAL FACTORS HUMIDITY Water vapour diffusion has to be considered in order to prevent the built up of condensate which can cause damages. In hot an humid climates with AC a permanent water vapour pressure difference between outside and inside air exists. High humidity penetrating in the concrete in combination with high temperatures can accelerate carbonation and corrosion of the reinforcement.
