Sustainable hotel climate with heat pumps


The building sector is to reduce its emissions by 6 % annually. 3 % was saved in 2021, 5.3 % was saved in 2022 (six million tonnes of CO2 on now 112 million tonnes of CO2). As of 2024, a newly installed plant will generally be operated with at least 65 % renewable energy.

Hotel operators and HVAC (Heating, Ventilation, and Air Conditioning) specialists are therefore well advised to work with partners who are leaders in their field in terms of sustainability. Kampmann has been focusing for many years on water-based air conditioning systems for heating and cooling. Operators are therefore ideally equipped for the use of heat pumps or other low-temperature systems – both in new and existing buildings.

“Heat Pump ready” label

We can assist you with one of the widest product ranges of units suitable for use with heat pumps – “Heat Pump ready” as it were.

Our label for your future-proof heating and cooling system.

“Venkon” fan coils are the ideal solution for use in hotel bedrooms. These units heat and cool with the efficient water temperatures that a heat pump, local heating network or other low-temperature system provides. They are also extremely quiet and, fitted with EC motors, are considerably more economical to operate than the still widespread AC technology. This alone can save 18,000 kilowatt hours and thus around 7,600 kilograms of CO2 annually in a 200-bed hotel. Over the last ten years, the energy costs could therefore be reduced by around €74,400.

We recommend a system consisting of a heat pump for heating mode and a chiller for cooling mode, plus Venkon fan coils in the hotel bedrooms. This results in an efficient and sustainable air conditioning system that offers maximum guest comfort, thanks to individual control. → To the Venkon

There are three options for the lobby, depending on the hotelier’s preference and the spatial situation. While Katherm HK trench technology can be discreetly hidden within the raised floor, practical KaCool D AF can be suspended from the ceiling, and Ultra Allround units are the perfect design-led statement units for high ceilings. All the systems provide heating and cooling and are also “Heat Pump ready”.

Retrofittable heat pump-based heaters

“PowerKon LT are heat pump-based heaters that work ideally with low system water temperatures if you wish to renounce fossil fuel-based energy sources. The units are capable of replacing existing heaters, which do not generally provide sufficient output when combined with a heat pump. → To the PowerKon LT

Manufacturer’s LCA

Kampmann provides so-called Environmental Product Declarations for its trench technology and Venkon fan coils – essentially the life-cycle assessment (LCA) for these products. This provides tested data quality for hoteliers who wish to have their sustainable hotel certified according to the DGNB German Sustainable Building Council, simplifying and facilitating the process.


For some time, sustainability in the hotel sector has been seen as image-promoting. This goes hand in hand with a healthy intrinsic motivation to do the right thing. This is evident in many lighthouse projects: hotels are way ahead of other types of building. However, now it is becoming increasingly clear that a successful strategy needs to go hand in hand with sustainable concepts. Businesses that act appropriately today will not be surprised by regulatory intervention in future.


A brief glimpse at the facts reveals why: The Paris Climate Agreement states that global warming is to be limited as far as possible to 1.5 degrees Celsius compared to the pre-industrial era. And while there is discussion about how legally binding this provision is under international law, the European Commission has created the European Green Deal to meet the Paris target. The Green Deal, in turn, needs to be translated into national legislation. In Germany, this is done by means of the German Federal Climate Protection Act with the objective of being climate-neutral by 2045 and setting individual sector-specific emission targets.
