house – since June/July 2014 we (Irina Merz and me) live in a
small house in the Northwestern part of Halle – beyond a
forest in a village („Dörfler“ und „Hinterwäldler“)
but with good connection to the city by bus and tram.
house is rather old, it was built in 1910. It was said to be
the poorhouse of the Protestant Church of the village. After
WorldWar II in the 1950ies and 1960ies, about 10 people lived
in the house: 2 families with children and old couples. In the
1980ies it was sold by the Church and after reunification to a
private person. In 1995 it was completely reconstructed. After
beeing sold again in the beginning 2000s it was for rent
several years. In Dec 2013 I bought the house and after another
renovation Irina and me were moving in in Jun – Aug 2014. In
Nov 2015 the heating and energy supply was completely
reconstructed. Since then we produce more energy than we need
over the year for household and heating. Additionally the
windows were newly made, we inserted a cistern and the carport
has to be reconstructed – with additional photovoltaic on the
carport is by now for Irinas and my car: A very small car for
me and one for her instruments and her to drive to schools and
kindergardens in and around Halle. She is teaching keyboard and
cars are electric cars and they are fed by sun power from the
roof of the carport – with a LiFePO4 battery.
cat died in May 2019 at an age of 16 years.
energy system: It is reported in some publications and we were
candidates to get a price of the Federal State of Saxony-Anhalt
for it, the „Green House Number“ – but we never got the
price. It consists of hybrid solar panels (totally 64 m² PVT
modules on the roof to the East and West) to save solar heat
energy and power supply. The heat is stored in 3 geothermal
borehole heat exchangers, each of them with a depth of 80 m in
our small garden. It was a bit difficult to find a drilling
team with such a small drilling rig.
