POSIBILIDADES DE REHABILITACIÓN ENERGÉTICA DE UN INSTITUTO DE EDUCACIÓN SECUNDARIA CONSTRUIDO EN 1990 APLICANDO EL ACTUAL CTE-DB-HE

Abstract

Applying the current Basic Document of Energy Saving of the Technical Building Code (CTE-DB-HE) ensures significant savings in terms of the non-renewable primary energy consumption and a significant reduction in the CO2 emissions of rehabilitated buildings. The current CTE-DB-HE requires that rehabilitated educational buildings demand limited amounts of energy, have energy-efficient lighting installed, and use a certain amount of solar energy for domestic hot water (DHW). Newly constructed educational buildings must comply with even stricter limits on energy demand and consumption. In this paper, two energy rehabilitation solutions are studied for a secondary school institute built in 1990 and located in Logroño (La Rioja), one for a rehabilitated building and the other for a new building. In both, external thermal insulation composite systems are used, the existing heating oil boiler for heating and DHW is replaced by a natural gas condensing boiler, the lighting installation is improved, and a solar support system is incorporated to cover part of the DHW needs.
