Temperature controll

Heat collections and storage

South oriented roof for heat collection

The house has only natural heat sources. Its primary heat storage is the cold and hot water sections (water has high heat capacity, ideal for storage)

Cold collected using the ground heat:
The cold section of water tanks partially sunken into the ground.
The system maximally uses the coldness of the incoming water.

Hot collected on the roof by water based solar heat collectors. The water circulates between the hot section tanks in the basement and the roof through the technical rooms between the levels using heat insulated pipes and solar energy powered pump.

Secondary heat storage is the basement walls and floor (basement insulated from outside). The heat is collected by circulating outside air if its temperature is adequate.

Temperature regulation

Water tanks in the basement

Primarily the basement provides the temperature regulation to the house, there is no heat insulation between them.

The basement and the house have heavy heat insulation from outside, as the water sections too, providing an insulated airspace in the basement.

The temperature of the airspace of the basement controlled by airflow and buffered by the bricks of the walls and floor.

The temperature in the airspace of the basement regulated with airflow flowing from the different temperature water sections and occasionally from outside.

When necessary, auxiliary forced airflow is possible from the basement to the living space of the house through slots in the floor using fans.

Air flow in water storage

Auxiliary temperature regulation by outside air ventilation

Automatic air ventilation occurs from outside to inside to the house 

• when outside temperature between 22-24 Celsius, or the outside air temperature is closer to the desired temperature than the inside

air goes in through highlights, goes out through technical rooms by natural airflow

Automatic air ventilation occurs from outside to inside of the basement

Outside air ventilation in the living space

when temperature outside

• above 22 Celsius and outside five days average high below 22 Celsius 

or

• below 24 Celsius and outside five days average high above 24 Celsius

and the basement temperature not on the side of the desired temperature.

air in and out through wall openings forced with fans

air direction according to the outside and inside temperature

Heat insulation

Outside air ventilation in the basement

Basement

• insulation with passive heat storage

wall
the wall is not a weight carrier structure
built with concrete blocks
insulated from outside with rigid foam insulation or rock wool insulation
water protection with folie

floor
built with bricks
insulated from outside with perlite insulation and rock wool insulation
water protection with folie

ceiling
no insulation

House

• solid wall by regular wood structure 
• rigid foam insulation
• no wires or pipes inside the wall

wall
inside plywood
insulated from outside with rigid foam double thickness
no plywood outside, simple siding

floor
no insulation

ceiling
similar structure like wall but outside plywood
