    Constructive standards for adapted thermal performance of educational buildings in Chile
    (2012) Ossio Castillo, Felipe Antonio; Veas Pérez, Leonardo; Herde, André de
    in the last years, there has been growing concerns on the impact of the conditions of comfort, on the performance of the students in educational buildings. Research has provided evidence that when the quality of indoor environment increases, there are positive impacts on productivity and reducing of absenteeism, among others benefits for the students and teachers. The quality of indoor environment depends, to a great extent, on the thermal behavior of the building. This behavior is determined, in turn, by the constructive characteristics. However, there is a lack of Chilean regulations to determine how more than 12,000 educational buildings should perform with regards to constructive characteristics in order to guarantee suitable quality indoor environment and comfort to their users. This study is based on the measurements performed, during winter and summer, to a school located in the Chilean Patagonia. At this school, the U-value and the air infiltrations of the envelope were experimentally measured. The thermal comfort was measured, according to the methodology proposed by Fanger. With this data, the theoretical energy consumption necessary to reach suitable levels of comfort were determined by means of a simplified method. Later, using the simplified method the power consumption, in other 3 climatic zones of the country was determined. The work concludes with recommendations of minimum standards for the educational dwellings with regards to their constructive characteristics which guarantee a suitable comfort of their users for the 4 climatic zones of Chile.

    Exigencias europeas para infiltraciones de aire: lecciones para Chile
    (2012) Ossio Castillo, Felipe Antonio; Herde, André de; Veas Pérez, Leonardo
    Los Estados miembros de la Unión Europea se han comprometido a reducir para el 2020 el consumo de energía primaria en un 20%. Dado que el consumo de energía en los edificios residenciales y comerciales representa aproximadamente un 40% del consumo total de energía final, se han definido una serie de políticas de Eficiencia Energética que mejoren el desempeño energético de las viviendas a modo de contribuir con el objetivo planteado. Una de las principales diferencias de estas políticas con la Reglamentación Térmica chilena radica en que esta última no considera las pérdidas térmicas por infiltraciones de aire, las cuales pueden mermar o anular cualquier avance que generen los actuales requerimientos nacionales. El presente estudio revisa los estándares de 14 países europeos en lo que respecta a limitación de las pérdidas por infiltraciones de aire, discutiendo su sistema de evaluación, unidades de medida y valor a modo de obtener lecciones para una futura consideración de este tipo de pérdidas en la actual Reglamentación Térmica chilena.
