Devices reducing energy demand in heating, cooling and ventilation systems and in hot water supply systems must be kept operational by the operator and used as intended. The systems must be operated properly. Components with a significant influence on efficiency must be maintained and serviced regularly; this requires expertise, that is the necessary specialist knowledge and skills. The Crafts Code remains unaffected. Compliance option: the operator may also meet the operational-readiness duty by taking other technical or structural measures that offset the effect of the energy-saving device on the annual primary energy demand. Section 57 additionally prohibits alterations to buildings and systems that worsen their energy quality. Further references: Sections 57 to 60.

Energiebedarfssenkende Einrichtungen in Anlagen und Einrichtungen der Heizungs-, Kühl- und Raumlufttechnik sowie der Warmwasserversorgung sind vom Betreiber betriebsbereit zu erhalten und bestimmungsgemäß zu nutzen. Die Anlagen sind sachgerecht zu bedienen. Komponenten mit wesentlichem Einfluss auf den Wirkungsgrad sind regelmäßig zu warten und instand zu halten; dafür ist Fachkunde erforderlich, also die notwendigen Fachkenntnisse und Fertigkeiten. Die Handwerksordnung bleibt unberührt. Erfüllungsoption: Der Betreiber kann seine Pflicht zur Betriebsbereitschaft auch dadurch erfüllen, dass er andere anlagentechnische oder bauliche Maßnahmen trifft, die den Einfluss der energiebedarfssenkenden Einrichtung auf den Jahres-Primärenergiebedarf ausgleichen. Flankierend verbietet § 57 Veränderungen an Gebäuden und Anlagen, die die energetische Qualität verschlechtern. Weitere Fundstellen: §§ 57 bis 60.
