Zero Energy Building



Heading 5

The notion that cooling and heating costs may be lower than lighting costs sounds far-fetched. The possibility that this can be achieved by simple, solid-state technology using natural materials, even more so. That such a system would not increase building or products costs appears, on the surface, to be science fiction. But this leap forward  can actually come from a novel combination of technical knowledge, practical considerations, and intelligent algorithms."

There are many applications where heating and cooling are desired, 'active insolation' is one novel way to manifest our technology. We call it 'active insulation' because it can heat and cool in addition to its natural ability to isolate. The product in development looks and behaves like ordinary insulation and can be integrated into prefabricated walls or insulation panels.




TheromTerra SmartWall is an add-on to prefabricated walls of residential and commercial buildings. 
The product enhances well-being while reducing energy expenses.
SmartWall creates personalized air condition with balanced temperature, humidity, and air quality.
It reduces heating and cooling costs by up to 50% by utilizing HumidityPower energy harvest and storage.
SmartWall can be integrated into many different construction methods and materials and can be fitted to many different architectural requirements.

ThermoTerra SmartWall is composed of  five components:

  1. HumidityPower: engineered absorption material packed inside a prefab wall, with air channels designed for maximal air flow.

  2. A structure of fans, ducts, and dampers, electronically controllable. 

  3. ActiveMemBrain unit: a connected controller with environmental sensors, selectively operating fans and dampers.

  4. ThermoTerra app for inhabitants.

  5. Dashboard for property managers.

Inhabitants have a comfort level related to their physique, activity level, time of day, etc. ActiveMemBrain learns this comfort level through app inputs. ActiveMemBrain continuously measures conditions inside and outside of the room and employs various strategies to achieve this comfort level such as: 

  1. Identify if external conditions are better than internal and replace the air inside (free cooling/heating).

  2. Add or remove moisture from inside the house by using HumidityPower storage.

  3. Heat or cool air using HumidityPower sorption capabilities.



Pilot of Retrofits Kit For Shipping Container


The pilot is focused on adding our technology to a retrofitted cargo container.

It is a common practice to use those containers as cheap, quick and mobile construction solution for offices, residential and logistic buildings - in army camps, refugee camps, and temporary installations. In many of those situations, energy costs are high, and a major percentage of those costs is derived from heating or cooling. Thus, a technology that can save energy has a high economic value.

 A large portion of domestic energy expenditure is spent on maintaining comfortable conditions within buildings.  Comfort is a function of both temperature and humidity levels. Temperature variations, to a certain degree, are ubiquitous to almost any climate and can be used to maintain stable temperatures by using thermal mass that acts as a heat buffer and reduces the peak (maximal and minimal) temperatures in the building. Thermal mass is variations, and requires the usage of heavy construction elements (stone, earth, water) in order to provide noticeable gains in comfort. 
Water vapor in the air that adsorbs onto or into an adsorptive material transfers a significant amount of energy to the material. The relative humidity also fluctuates daily and seasonally, but no commercial solution is currently offered that utilizes these fluctuations in relative humidity in order to harvest energy. This invention deals with the utilization of relative humidity fluctuations in order to stabilize the peak temperature and humidity within buildings, thus reducing the need for more expensive energy measures (electricity, gas) to control indoor temperature and humidity.
Between the compounded factors of increasing technological advancement of an ever-increasing global population on the one hand, and global warming (be it anthropogenic or not) on the other hand, the energy expended on temperature and humidity control represents a rising fraction of the total worldwide energy load.  There is thus a pressing need for novel, energy-efficient temperature and humidity control.mostly suitable for climates with strong temperature
