Technical feasibility

SECTION I: Testing

 

1 Has the R & D result been tested?
Yes the R&D result has been tested.

  

1a In what mode has the result been tested?•           Prototype

•           Pilot Application

•           Alpha/BETA testing

The R&D result has been tested in large projects as:

Thessaloniki’s White Tower: monitoring and evaluation of indoor climate and air quality conditions in order to be used as a City Museum

Church of Panagia Achiropoiitos: heating study

The R&D result has also been applied many times in schools and buildings.

1b. Τesting results
Thessaloniki’s White Tower

The White Tower is a historical building in the port of Thessaloniki, and it is considered the city’s trademark. LHTEE’s was called to examine the building in order to be used as a City Museum. The specific objectives were to monitor and evaluate the building’s indoor climate and air quality conditions, to determine the necessary interventions for the improvement of the indoor environmental quality and to propose methods for the limitation of energy demands. The team of LHTEE had to take under consideration the restrictions imposed by the building’s age, features and significance. The work was carried out in three main phases:Monitoring for a whole year indoor climate conditions and CO2 concentration

Processing of the data collected regarding temperature, humidity, air flow and CO2

Proposing of solutions for thermal and air quality conditions improvement, as ventilation through air dehumidifiers, well placed window fans and replacement of the existing internal doors with new perforated doors

 

Panagia Achiropoiitos

LHTEE’s objective for Panagia Achiropiitos was to inspect and evaluate the church’s thermal comfort conditions and select the most effective heating method. Meanwhile the artistic, monumental and aesthetic value of the church had to be maintained. Within this framework a thorough inspection and evaluation of the thermal comfort conditions in the church was carried out, using an infrared camera, hygrometers and thermometers, providing enough data for the evaluation of the thermal comfort conditions prevailing in winter. After comparing alternative solutions, floor heating, warm-air heating, integrated pew heaters, oil or gas heaters, radiation heaters, and infrared heaters, the latter were considered to be the most appropriate. They covered the demand for thermal comfort without incommoding the interior environment and the aesthetic and historic value of the church.

In both cases the R&D result managed to achieve its goals efficiently. These goals were:

- to measure indoor air quality conditions

- to measure thermal conditions

- to propose methods for the improvement of air quality

- to propose methods for the improvement of thermal conditions while minimizing energy costs

  

SECTION 2: Current Stage of Development

 

2a To what extent does the development team have technical resources for supporting the production of a new product? (Researchers, human resources, hardware, etc. )
The development team has both the human resources as well as the technical resources to offer this new service. The R&D result is a result of collective effort and the team of developers is available to work on full scale for the offering of the service.

 

2b What are the technical issues that need to be tackled for full deployment, if needed?
There are no technical issues that can cause problems in the deployment of the service.

 

2c What additional technical resources are needed for the production of this new product?
The additional technical resources are 2 new air quality measurement devices and the signing of a contract for the maintenance of the machinery used. These additional resources, even though they are not necessary for the deployment of the service, however they could contribute in the quality of the service provided.

 

2d Overall assessment of the current stage of technical development.
The R&D result is ready for application in large scale.
