WHY be NORMAL?
Not just nice words and pretty pictures - environmental protection in practice is the motto!
During the development of BIRDY and BAMBY, great importance was attached to resource conservation and environmental compatibility right from the start,
both in the design and in production.
For example, when creating the CNC programs for the milled parts, care was taken to maximize the use of raw materials
Many parts that were initially sourced from external suppliers could gradually be manufactured in-house thanks to expertise
and the corresponding equipment.
This means a gain in flexibility, a reduction in transport routes and no packaging waste
The use of adhesives and solvents,for example,
has also been reduced by around 35% thanks to ever more advanced processes.
This has enabled us to reduce our environmental impact to a not inconsiderable extent and, despite all market influences,
keep our prices moderate for long periods
However, the largest item in the environmental balance sheet is the energy requirement
And it is precisely here that the greatest environmental relief has been achieved
Back in 2001, an experimental angular power plant was put into operation on the roof of the company building.
This "Westernmill", conceived and assembled from leftovers "on the fly" over a weekend,
was so convincing, productive and obviously well-designed (it even survived the Kyrill storm without damage)
that it operated reliably and trouble-free until the bearing failed in 2018, more or less continuously delivered 120-180 watts
That doesn't sound like much, but if you consider that a lapptop requires around 60-80 W,
this covers a significant proportion of the electricity requirements of the entire office
Even small things matters
In 2010, also as an experiment, an approx. 2x1m solar thermal collector was installed on the south-facing roof of the building
using existing pipes, sheet metal, glass panes and insulating material
This was so successful that, with minor repairs, it provided hot water from around March to September completely without fossil fuels
until it was dismantled in 2023.
The systematic refurbishment of the building fabric in 2020, the conversion of the heat generation system in 2021,
the modernisation of the lighting, the conversion of the vehicle fleet and, last but not least, the change in behaviour,
reduced the total energy requirement by over 80 percent!
Since 2021, a PV system with an installed capacity of just under 30 KW peak,
a storage system of around 29 KWh and an inverter capacity of a good 30 KW has been in operation.
As this system is operated purely as an island / supply system separate from the general supply grid,
only around 3500 KWh of electricity per year was purchased from the local supplier in 2023 and 2024.
No heating oil, no gas, just 500 litres of petrol for the combustion vehicle
That's it
This amount also includes the "heating current" for heating buildings and hot water,
as well as the operating current for the electric car.
These parts are supplied from the grid from mid-November to around mid-February.
Incidentally, the system was built from our own funds, there were no grants, subsidies or tax savings,
nor is there a feed-in tariff - which would not even be physically possible with an island system.
The conventional oil-fired central heating system has been out of service since 2021 and was only kept as a reserve
It was decommissioned and dismantled at the beginning of 2025.
This means that as the owner of a BIRDY or BAMBY, you can be sure that
through the optimum use of materials, intelligent production and sustainable energy generation
every effort is made to maintain an environment
in which it is a pleasure to travel with BIRDY or BAMBY without a guilty conscience
Much has been achieved, but we are not satisfied with that.
Our environment is worth every effort!
Now and in the future
