How much can we save with CO2 solutions?

Ventilation control is one of our major markets. You will find five million of our sensors in different locations around the world! In a commercial building the amount of people visiting can vary extensively. If you need to heat or cool the building you can save a huge amount of energy by changing the air flow. Your choice is fixed or demand control (in our case CO2 level) An example is the Swedish Government chain of liquor stores, they installed our CO2 sensors with an automated air flow system in all their stores. Within ten months the investment was paid and thereafter it is a saving in cost and on the environment.

In a set of 13 countries participating in the IEA Energy Conservation in Buildings & Community Systems Program, the primary energy1  consumption attributable to the ventilation of all buildings is estimated to equal 9% of the total primary energy consumption of the countries. An estimated 3 exojoule (EJ) of energy2 are used annually to ventilate US residential buildings, approximately 30% of the total energy used in these buildings. In the US service sector (e.g., commercial, institutional, and government buildings), the estimated energy consumed for ventilation is 1.5 EJ, approximately one quarter of total service-sector building energy use (Orme, 1998). The annual carbon dioxide emissions attributed to ventilation are approximately 1,000 and 800 million tons for the US residential and service sectors, respectively. Climate has a large influence on the energy required to thermally condition ventilation air. In Europe, most of this energy is used for heating the ventilation air. In the US, significant energy is used for both heating and cooling. In the humid Miami climate, 86% of the energy is used to remove moisture from the ventilation air.**

1. Primary energy use is higher than the energy consumed within the buildings because of the losses during energy production and transmission to the building.

2. Energy consumed in the building, which is less than primary energy consumption

Adaptable platforms

Most of our OEM customers need  ready to install products and solutions. You will find your solutions on one of five Adaptable Platforms where we can start our journey together. You can buy our sensors as stand alone (Sensor Core), mounted on a pcb (Sensor onBoard) with other functions such as communication, power and other sensors.

You will also find that we have extended warranties when we deliver white label casing (Sensor inCase) with all functions.
