Heat Insulation Detached House
A 100 square meter detached house (year of construction 1960) which is non-insulated uses an average of 3700 litres heating oil per year. How much does an up-to-date low-energy build house use?
Correct answer: Up to 700 litre !

About one third of the annual energy consumption in Germany is used in heating buildings, according to the German Energy Agency. Heat insulation provisions offer a large energy saving potential. The "Katalyse" environment database reports that a house build in 1982/94 uses, as per Heat Insulation Ordinance about 1500 litre heating oil, a house build in 1995 uses, as per Heat Insulation Ordinance, about 1000 litre and a low-energy house on the current status only uses about 500-700 litre.

An important contribution to an environmentally-friendly and ecological protection of energy supply for the future of mankind is the use of geothermic. The use of geothermic is divided into the sections of deep geothermic and near-surface geothermic. The deep geothermic is the warmth of the earth found in depth of over 15 m up to more than thousand meters.
Even though the temperatures of the near-surface are quite low with about 7-11° C the existent heat is quite cost-effective with the use of small and medium sized near-surface heating equipment. The most important implement for the use of geothermic for the house construction is the heat-pump. To be able to use the heat-pump it is necessary to have a heat source and a technique to use this heat source to employ the energy through the heat-pump in the house construction.
Geothermic: 4 drill holes up to a depth of approx. 60 metres. Carrier liquid consists of ethylene-glycol.
Flow temperature - 2
Return temperature + 3 degrees
Standard: 1 KW operating power = 4 KW usable heat

Environmentally-friendly heating systems with modern heat-pump techniques are the future. Heat-pumps work with unrivalled low-price operational costs as a large part of the required energy is drawn from the environment and oil or gas as an operating power is not needed.
We differentiate the following systems:
The air/water heat-pump: for external and internal placement uses the external air as an energy source for all-season temperatures of +35 °C to -25 °C.
The brine/water heat-pump: uses the warmth from the sun or waste heat stored in the ground.
The water/water heat-pump: draws the heating warmth from the constant temperate ground water with temperatures of +8 °C to +12 °C, even during the winter season.

Barrier-free Building (Source: Enderwitz Gmbh / www.enderwitz-gmbh.de)
For example bathrooms: If you think 20 years ahead into the future - what will your needs be then and will you still be comfortable as a human. Barriers which are not obvious now can suddenly become hurdles. To plan and implement such a bathroom is not an easy task. Some architectural points are obvious, if for example you require the help of a wheelchair: thresholds in room doors, a shower tray with a high entry or missing handholds. Bathrooms are usually small in dimension and in design unfavourable. This constricts usability which is significantly defined by size and available movement areas. Germany has standards for planning a barrier-free bathroom. The DIN (Deutsche Institut für Normung) has many guidelines and advice on this topic. Especially DIN 18024 (part 1) and 18025 (part 1 and 2) are decisive for building and planning barrier-free bathrooms.
The private house construction increasingly prefers an on-grade shower with fixed, likewise tiled splash walls to a conventional shower tray. Fitted with a closely mounted floor drain, an additional watertight coating and a pre-set decline is easily and safely installed by a professional service technician.

Assembly into wooden floor:
Cut out the existing wooden under-floor and wooden joist to the exact measurement of the element. Building of a new wooden under-floor on the required level (height) on which the element is to be installed.
