Solutions for a radical
water use in households is possible without the risks for
public health and reliability.
Three integrated water systems can reduce 50% water consumption
and 5% of the gas consumption:
1. A rainwater system that makeswashes with rainwater possible.
2. A combi toilet system that usesgrey water from shower,
bath and washing machine for toilet flushing.
3. A shower heat recovery system with a counter flow principle
that can be used together with the grey water system.
Energy demand of households
can be halved with a new concept for climate control that
is able to heat or cool a specific environment quickly on
demand with only one installation controlled by sensors and
Lower room temperature is
compensated by heat radiation in winter and cold panels on
the ceilings keeps
the inhabitants cool in the summer.
The largest part of the
energy consumption per capita still is used for home heating
and hot water.
That means an extensive contribution to CO2-emissions
A number of developments are taking place at this moment like
insulated houses, large windows on the south-side and new
heat pumps and Micro-cogeneration as successors of
the High-Efficiency gas-fired boilers.
An alternative is a heat pump that operates directly by free
piston stirling engine. Such a system can generate both heat
and cold and electricity. Moreover the system can operate
