Regulation-wide (no rule set) Whoever constructs a building Owners of existing residential and non-residential buildings heated to at least 19 degrees Celsius for at least four months a year Existing buildings where external building elements are renewed, replaced or installed for the first time Owners of existing buildings or building networks replacing the heating system Existing buildings with a gas, heating oil or LPG heating system newly installed after 29 July 2026 Non-residential buildings with a system rated output above 70 kilowatts Operators of heating, cooling and ventilation systems and hot water supply systems Heat pumps in buildings with at least six dwellings or self-contained units, commissioned after 31 December 2023, without remote monitoring and without a maintenance contract Water-based heating systems in buildings with at least six dwellings or self-contained units Water-based heating systems after installation of a heating system in buildings with at least six dwellings Operators of air conditioning systems and combined air conditioning and ventilation systems with more than 12 and up to 70 kilowatts of cooling output Operators of air conditioning, combined air conditioning and ventilation and ventilation systems above 70 kilowatts Developers and owners on construction, alteration, sale and letting Sellers, landlords, lessors, financial lessors and estate agents Developers and owners of buildings to be constructed and of altered buildings Companies carrying out works on or in existing buildings in the course of business Inspecting persons Building owners holding a contractor declaration Buildings where distribution equipment, air conditioning systems, ventilation systems or pipes are installed or replaced Buildings to be constructed, except buildings serving national and alliance defence New non-residential buildings with more than 250 square metres of useful floor area Existing non-residential buildings above 500 square metres of useful floor area undergoing alterations of external building elements Existing public non-residential buildings above 2 000 square metres of useful floor area Existing public non-residential buildings above 750 square metres of useful floor area New residential buildings and new roofed car parks Existing public non-residential buildings above 250 square metres of useful floor area Owners of existing non-residential buildings built before 1996 without biomass, heat pump or district heating Owners of existing non-residential buildings New buildings above 1 000 square metres of useful floor area

Owners of a residential building and owners of a non-residential building heated by its intended use to at least 19 degrees Celsius for at least four months a year must ensure that top storey ceilings not meeting the minimum thermal insulation requirements of DIN 4108-2 are insulated so that the thermal transmittance does not exceed 0.24 watts per square metre and kelvin. The obligation is deemed met where the roof above is insulated accordingly instead, or already meets the minimum thermal insulation requirements. Variants: where the insulation is placed within ceiling cavities and its thickness is technically limited, the requirement is deemed met if the greatest possible thickness under the recognised rules of technology is installed, with a design thermal conductivity of 0.035 W/(m·K), or 0.045 W/(m·K) for blown-in insulation or insulation from renewable raw materials. The same applies to insulation between rafters. For a residential building with no more than two dwellings, one of which the owner occupied on 1 February 2002, the duty falls on the new owner only after a change of ownership, with a two-year deadline; it lapses where the expenditure cannot be recovered within a reasonable period.

Eigentümer eines Wohngebäudes sowie Eigentümer eines Nichtwohngebäudes, das nach seiner Zweckbestimmung jährlich mindestens vier Monate auf Innentemperaturen von mindestens 19 Grad Celsius beheizt wird, müssen dafür sorgen, dass oberste Geschossdecken, die nicht den Anforderungen an den Mindestwärmeschutz nach DIN 4108-2 genügen, so gedämmt sind, dass der Wärmedurchgangskoeffizient 0,24 Watt pro Quadratmeter und Kelvin nicht überschreitet. Die Pflicht gilt als erfüllt, wenn anstelle der obersten Geschossdecke das darüber liegende Dach entsprechend gedämmt ist oder den Anforderungen an den Mindestwärmeschutz genügt. Varianten: Wird die Dämmung in Deckenzwischenräumen ausgeführt und ist die Dämmschichtdicke technisch begrenzt, gilt die Anforderung als erfüllt, wenn die nach anerkannten Regeln der Technik höchstmögliche Dämmschichtdicke eingebaut wird; dabei ist ein Bemessungswert der Wärmeleitfähigkeit von 0,035 W/(m·K) einzuhalten, bei eingeblasenen Dämmstoffen oder Dämmstoffen aus nachwachsenden Rohstoffen 0,045 W/(m·K). Entsprechendes gilt für eine Zwischensparrendämmung. Bei einem Wohngebäude mit höchstens zwei Wohnungen, von denen der Eigentümer eine am 1. Februar 2002 selbst bewohnt hat, trifft die Pflicht erst den neuen Eigentümer nach einem Eigentümerwechsel, mit einer Frist von zwei Jahren; sie entfällt, soweit die Aufwendungen sich nicht innerhalb angemessener Frist erwirtschaften lassen. Weitere Fundstellen: § 35 Absätze 1 bis 4, § 102.
