Sustainability at Boardinghaus Eching
Eco-friendly business practices and the economical use of resources are a daily routine for us! Find out which measures we have taken and how you can help us to reduce the ecological footprint of our accommodation.
Power and heat
- Modern combined heat and power plant
- Energy storage system
- Solar heating system
- Photovoltaic system
- Supplemented by green electricity
Combined heat and power plant
Our combined heat and power unit produces an electrical output of approx. 20 kW and, by means of cogeneration, a thermal output of 39 kW. Similar to a car engine, energy is generated by using a fuel. However, unlike the combustion engine in a car, the waste heat generated during combustion is fed into a connected (coupled) heating system and is thus used for heating and hot water. On-site production eliminates the losses associated with distributing electricity and transporting heat over long distances. As a result, our power plant achieves an overall efficiency of around 95% under full load, earning it the highest possible energy efficiency rating of A++.
Photovoltaics & Energy Storage
During the day, a solar thermal system contributes to the boarding house's hot water supply.
Added to this we generate CO₂-free electricity from our 3 photovoltaic systems with a combined maximum output of approx. 47 kW.
On sunny days, they charge 3 energy storage units, which together can store up to 42 kWh of electricity and absorb the surpluses during periods of low demand and compensate for the increased energy demand during peak loads.
On average, each person in Germany consumes about 1,300 kilowatt hours (kWh) of electricity per year, which corresponds to about 3.5 kWh per day. Our combined heat and power plant runs at full load for an estimated 5,500 hours a year, generating over 100,000 kWh of electricity, enough for about 80 people. Our energy storage units, in turn, store enough energy to supply an average of 12 people with energy for an entire day.

Saving measures
- Ventilation system with heat recovery
- Energy-efficient construction of our new building (KFW efficiency house standard 55)
- Throughout the house we use energy-saving LEDs
- Presence detectors ensure that electricity is only consumed when it is really needed
- Flow regulators reduce water consumption
- Energy-saving groundwater cooling of the restaurant
Heat recovery system
In the buildings constructed in 2020, a ventilation system replaces the stale air in the living areas with fresh air from outside. The heat contained in the exhaust air is stored in a heat exchanger and almost completely transferred to the incoming fresh air. This significantly reduces heat loss. Additionally, special filters purify the outside air of pollen and dust, ensuring a pleasant indoor climate where even people with allergies can breathe freely.
Groundwater cooling
The on-site restaurant is also a great place to be on hot days, as it features an environmentally friendly groundwater cooling system. Cold groundwater is extracted, filtered and fed into the roof of the building, where heat is exchanged. This method of cooling consumes virtually no electrical energy, only the pumps require electricity to overcome the friction of the water in the pipes.
Environmental protection
- We avoid the use of disposable items
- We practice rigorous waste separation and also offer this option to all guests
- Extensive unsealing of the outdoor area relieves the sewer system during heavy rainfall and thus protects against flooding
- With our charging sockets for electric vehicles and e-bikes, we support environmentally friendly mobility

Bavarian Environmental and Climate Pact
Boardinghouse Eching has been participating in the Bavarian Environmental and Climate Pact since mid-2021. The initiative of the Bavarian State Ministry of Environmental and Consumer Protection aims to motivate companies to make voluntary efforts to protect the environment. The prerequisite: proactive environmental protection efforts that go beyond the legal requirements and the promise to continue operating sustainably in the future.
How you can contribute
- Air-dry your laundry. Tumble dryers are very energy intensive appliances!
- Have towels and bed linen washed only when necessary
- Do not wash your laundry hotter than necessary
- Forgo your car: There are parking facilities for bicycles both in the underground car park and on the premises. Most destinations in the surrounding area are easily reachable by bike
- Consistently separate your waste
- The ventilation system in apartments 1 to 83 provides you with fresh air at all times. In order to minimize heat loss, manual airing out should be avoided as far as possible. Otherwise, the following applies: Brief and intensive airing out for five to ten minutes several times a day, to avoid excessive cooling of the walls and floor
- Pull the plug: avoid stand-by mode
