Intelligent management system energy efficiency for building architectonical envelope restoration incorporating Intelliglass Technology.

The objective of singer project is the design and development of an intelligent system able to manage the energy through building architectonical envelope restoration, aiming at high energy efficiency incorporating Intelliglass Technology.


The project suggests new strategies oriented to improve building energy efficiency through the architectonical envelope restoration.

For this, advantages of active systems radiaglass and ithermglass are studied while integrating in the buildings selected as pilots. Radiaglass and ithermglass are both glazing with a water chamber inside, unlike the typical air chamber.  The main new feature of this active glazing is that water is flowing through the chamber, allowing to manage the received warmth on the glass facade and to direct the energy excess toward other building areas with energy deficiency.

Sensors and trasnceptor devices have an identificator andan unique IPV6 direction. This allows remote communicaton to the devices from anywhere through internet.

This project attempts to design, develop, integrate and validate a new management system. It will allow to optimize building energy efficiency, combining construction technologies with communication and information technologies.

The development of this energy management system must allow to measure the building internal and external weather condition, its electrical consumption and its spaces occupation in order to measure the thermal loads.


CeDInt activity

Cedint has designed a monitoring system able to measure the thermal consumption of water circulating through the intelliglass windows. The thermalconsumption unit is the therm (th), whis is equivalent to  one million of calories. Besides, superficial temperatures in different points of the windows are measured to monitorits thermic performance and behavior.  The system is based on a wireless sensors network controlled by a management  platform  which stores all the information in a database and provides easy and intuitive access.

In order to check the monitoring network system, cedint has developed some test using both, its laboratories and dmae facilities.

Cedint laboratory test has been carried out through  a demonstrator window provided by dmae, simulating an intelliglass system. 


Different sensors (temperature and humidity) are located on bothsides of the window, simulating interior and exterior locations. Sensors virtually lie on the glass so the measure may be seen as superficial.


In addition, cold and hot water circuit temperature are measured to carry out the analysis and measurement of therms circuit.

In order to measure the water temperature within the circuit, immersion housings have been used. This,allows to put temperature probes practically inside the water stream circuit.

After placing temperature probes inside, the housing is filled with oil and sealed with silicone. The oil allows water temperature transmission from the housing to the sensor much easier and faster. 


The first part of the second pilot has been installed at one DMAE office. The office has three walls with Intelliglas windows, all of them oriented differently. The main objective consists in analyzing the operation of all possible temperatures system measurement.


Next images show a real installation and how the different sensors are located:



The second part of the second pilot is located in dmae shed, specifically on a portable demonstrator composed of two intelliglass windows and a whole water closed circuit system.
