THE SOLAR ENERGY
It is a green
energy
Everybody can
use it
It saves our
money
Untapped
energy
Can be used in
several forms
In 60 min. the sun provide
energy to the earth more than
the human use in One year.

THE PROBLEM
How to store
the solar energy
for evening and
night use?
We
need to
heat in
winter
What if
it is a
cloudy
day?
Can we do
it without
installing
a boiler?
YES WE CAN

THERMALY ACTIVATED BUILDINGS - TABs
Floors, ceiling, walls and
beams are all used to
heat the building.
Heating pipes are
distributed everywhere.
Heating water is
circulating in the building
structure 24/24h.
Supply temperature lower
than 30ºC is enough to
provide a high comfort.

SYSTEM AND EQUIPMENT
The remaining heat is
stocked in a big buffer
tank for continuous use.
The domestic hot water
is charged by the solar.
A smart use of the hot
water stratification in the
buffer result in more
energy saving.
Many heating source can be
connected to the buffer,
like heat pump, solid fuel
boiler or even a gas boiler.

COLLECTIVE SYSTEM
Improved energy efficiency,
plus flexibility of use.
The solar energy and other sources
are cached in a central buffer.
Each user can chose the
mode using the solar energy,
for domestic hot water,
radiators or floor heating.
A heat meter can be added
to allow an exact calculation
of the water and energy
consumption of each dwelling
