Energy consulting for apartment buildings
Energy consulting for apartment buildings and owners' associations in Berlin: one analysis for the whole building
Owners' associations, landlords and property managers receive an on-site energy consultation for the entire building from us: envelope, gas floor heaters, funding per unit and a renovation roadmap that holds up at the owners' meeting.
What makes energy consulting different in an apartment building
In a detached house one owner decides. In a Berlin apartment building twenty decide, plus a property manager, tenants with their own gas boilers and a heat plan that assigns the building to an area type. Energy consulting therefore has to deliver more than a list of measures: costs per unit, funding per unit and a result that can be resolved at the owners' meeting.
Our dena-listed energy efficiency expert surveys the building on site, balances envelope and systems according to BAFA requirements and produces the report or the individual renovation roadmap. On request we present the result at your meeting; BAFA funds this presentation as well.

What does energy consulting for an apartment building cost?
The fee depends on the number of units and the scope, typically 1,800 to 4,000 euros. BAFA covers 50 percent of the eligible fee, at most 850 euros from three units, plus up to 250 euros for presenting the report at the owners' meeting. We file the application as a listed expert; BAFA deducts the grant directly from the fee.

Energy consulting for apartment buildings in Berlin: what the report states per unit
A consultation report for a detached house lists measures and total costs. For an apartment building that is not enough, because the meeting decides on amounts per unit and the manager allocates them by co-ownership shares. Our report therefore states every measure three times: total cost, cost per unit and the grant per unit according to the tiers of KfW heating funding or BAFA envelope funding. A building with eight units has, for the heating, 28,000 plus five times 15,000 plus two times 8,000, that is 119,000 euros of eligible costs, on which the 30 percent basic grant applies.
Added to this is the building's energy balance according to BAFA requirements: heat losses through facade, roof, basement ceiling and windows, efficiency of the systems, hot water and ventilation. The order of measures follows from these figures. In Berlin period buildings the top floor ceiling or the basement ceiling almost always comes first, because they bring the largest effect per euro and need no resolution about the facade.
Replacing gas floor heaters: why centralisation determines the price
In most Berlin period buildings every flat has its own gas boiler. The path to a heat pump or a district heating connection therefore runs through centralisation: a shared boiler room, new risers through the stairwell or disused chimney flues and a transfer station per flat. Price and construction time arise there, not at the appliance. The consultation calculates both routes, heat pump as a cascade in the courtyard or on the roof against district heating where the building lies in a heat network area, and states both per unit.
The 16 percent climate speed bonus applies when replacing a gas floor heater without an age limit, but only for the unit the owner occupies at the time of application. In a mixed-use building the owner-occupiers receive it for their flat, rented units stay at 30 percent. Exactly this distribution is in the report, so the meeting does not calculate with a figure that only applies to some owners. For landlords in addition: funding is deducted before the modernisation surcharge and lowers it too.
Energy consultant for the owners' association: resolution, management and the BAFA application
The association resolves to commission the energy consultation at the meeting, usually on the manager's proposal. We supply quote, scope of services and the funding calculation so the agenda item is complete. After the resolution we file the application with BAFA as a listed energy efficiency expert on behalf of the association; approval usually arrives within a few weeks, and only then does the consultation begin. The 50 percent grant, at most 850 euros from three units, is deducted directly from the fee.
On request we present the result at the next meeting, which BAFA funds with up to 250 euros extra. In our experience this is the step that decides on implementation: owners approve measures whose costs, funding and order they have understood. Which majority a later renovation resolution needs is clarified by the manager or a specialist lawyer; we supply the cost basis on which it is passed.

Frequently asked questions about energy consulting in apartment buildings
The association via its manager. Commissioning an energy consultation is an act of proper management and is resolved at the meeting; which majority the later renovation needs is clarified by the manager or a specialist lawyer. We supply the documents for the agenda.
50 percent of the eligible fee, at most 850 euros for buildings from three units. For presenting the report at the owners' meeting there are up to 250 euros extra. The applicant is the owner or the association; our listed expert files the application.
If the association plans several measures over years, the iSFP is the right format: it fixes the order and adds 5 percentage points of grant on insulation, windows and ventilation. If it is only about the heating, the consultation report is enough, because the iSFP bonus does not apply to KfW heating funding.
That is the most common and most expensive case in Berlin period buildings: the path to a heat pump or district heating runs through centralisation with new risers and a transfer station per flat. The consultation calculates both paths and states costs per unit. The climate speed bonus applies when replacing gas floor heaters without an age limit, but only for owner-occupiers.
The Senate adopted the heat plan on 16 June 2026. It assigns every area to a type: heat network area, examination area or decentralised supply with heat pumps. It is guidance, not an obligation: no compulsion follows from the assignment, neither to district heating nor to a heat pump. In the consultation we check whether a district heating connection is realistic for your building.
For heating replacement the special rule of section 559e BGB applies: 10 percent of the costs per year, minus funding, capped at 0.50 euros per square metre within six years, and only if funding was actually used. Funding therefore lowers the surcharge too. Concrete amounts for your building are calculated by the manager or a specialist lawyer; we supply the cost basis.
From BAFA approval to the finished report four to eight weeks, depending on how complete plans, consumption statements and system data are. The inspection itself takes half a day to a day. BAFA approval usually arrives within a few weeks; we may not start before, otherwise the grant is lost.
Floor plans and sections if available, heating cost statements of the last three years, year of construction and details of previous measures on facade, roof, windows and heating, the number of units with living areas, and maintenance records of the systems. Anything missing we record during the inspection, which only takes a little more time on site.
Yes, in heat network areas that is part of it. We compare the network connection with a central heat pump per unit over 20 years, including connection costs, energy price and funding. Whether a connection is possible and what it costs is answered by the network operator on request; we submit the request with your building data.
