AB Improving the detection of thermal insulation in buildings –whichincludes the development of models for heating and ventilation processes andfabric gain - could significantly increase building energy efficiency and substantially contribute to reductions in energy consumption and in the carbonfootprints of domestic heating systems. Thermal insulation standards are nowcontractual obligations in new buildings, although poor energy efficiency is often a defining characteristic of buildings built before the introduction of thosestandards. Lighting, occupancy, set point temperature profiles, air conditioningand ventilation services all increase the complexity of measuring insulationefficiency. The identification of thermal insulation failure can help to reduceenergy consumption in heating systems. Conventional methods can be greatlyimproved through the application of hybridized machine learning techniques todetect thermal insulation failures when a building is in operation. A three-stepprocedure is proposed in this paper that begins by considering the local buildingand heating system regulations as well as the specific features of the climatezone. Firstly, the dynamic thermal performance of different variables is specifically modelled, for each building type and climate zone. Secondly, CooperativeMaximum-Likelihood Hebbian Learning is used to extract the relevant features.Finally, neural projections and identification techniques are applied, in order todetect fluctuations in room temperatures and, in consequence, thermal insulation failures. The reliability of the proposed method is validated in three winterzone C cities in Spain. Although a great deal of further research remains to bedone in this field, the proposed system is expected to outperform conventionalmethods described in Spanish building codes that are used to calculate energeticprofiles in domestic and residential buildings.
