Solar thermal energy technical guide

The Institute for Energy Diversification and Saving (IDAE) and the Solar Thermal Industry Association (ASIT) have revised, updated and expanded the Solar Thermal Energy Technical Guide, due to the recent changes to section HE4 of the Technical Building Code.

Professionals in the solar thermal sector need proven and recognized information to serve as a guide of good practice during the sizing, design, execution, operation and maintenance of installations. Until now, the technical reference information was an integral part of the aforementioned current legislation and was limited to the minimum technical requirements.

The Solar Thermal Energy Technical Guide goes beyond the objective of establishing minimum technical specifications and offers extensive information, which will bring added value to professionals in the sector. The aim of this technical guide is therefore to promote solar thermal energy and to collect a series of recommendations, based on the experience accumulated by the large number of solar thermal installations carried out in recent years, to facilitate the tasks of the agents who ” they are involved in the design, execution, operation and maintenance tasks related to this type of installation. The requirements for safety, efficiency, quality, reliability and durability of solar thermal installations are established in such a way that they function properly throughout their useful life and are also durable. as possible.

The guide will serve to mejorar la calidad de las instalaciones solares in general, y además para fomentar otras posibles aplicaciones de la energía solar térmica diferentes de agua caliente sanitaria, como por ejemplo la calefacción y refrigeración, bien directamente en edificios o red heat.
