EENSULATE demonstration sites

Public Library San Giovanni - Pesaro, Italy

Pilot description

Hosted by the ancient monastery of the Frati Minori Osservanti, once annexed to the church of San Giovanni Battista (one of Pesaro’s most beautiful architectural works) and planned by the Della Rovere family’s architect Girolamo Genga, the library San Giovanni is an example where the historical (the façade facing the access street) and contemporary architecture elements coexists. Those elements are a large windowed eyelet for the lightening of the public spaces and a curtain walling façade in the building main entrance. The building act as a demo for testing EENSULATE glass in windows in the historical façade. Although Pesaro municipality is not a project partner, they gave the availability of this building as demonstration case of EENSULATE project.

Intervention details

The foreseen intervention is the implementation of EENSULATE glass based on VIG (Vacuum Insulated Glass) technology in a door-window located in an area of the building organized ad an open space hosting a kid-library. The VIG will be installed directly in the original frame of the door-window, minimizing the works to be carried out as well as the waste of material. Nevertheless, the simple substitution of the glass part of the door-window with a high insluating VIG encreases the thermal capacity of the window system with a consequent benefit for the people inside the room. The door-window is composed by two parts, the above one is fixed (without the possibility of opening) and the bottom part is a sort of emergency door exit conducting directly outside the building.

Monitoring phase

Monitoring of the intervention consists of meassuring the indoor thermal conditions and thermal comfort conditions of users (i.e. the PMV-Predicted Mean Vote) as well as measurement of environmental and personal parameters such as:

  • Indoor air temperature Ta [°C]
  • Indoor relative humidity RH [%]
  • Mean radiant temperature MRT [°C]
  • Metabolic activity of the subject M [met]
  • Clothing level of the subject Icl [clo]

The performance of the glazed system is also monitored in terms of thermal transmittance and radiative property. The following parameters will be measured:

  • Indoor and outdoor glass surface temperature [°C]
  • Indoor and outdoor air temperature [°C]
  • Heat flux across the glass [W/m2]
  • Indoor and outdoor solare irradiance [W/m2]
  • Indoor and outdoor luminous flux per unit area [lux]

Polish School - Dzierżoniów, Poland

Pilot description

The Polish school is located in a curtain wall building that the Dzierżoniów municipality would like to refurbish improving the façade performances. The renovation intervention consists of introducing glazing curtain walls enhancing the building profile to zero energy in line with EU and national targets for public buildings. After the implementation of EENSULATE solution, the building will be a real show case proving the project results to both national and international stakeholders, enhancing also the image of Dzierżoniów municipality.

Intervention details

The renovation intervention consists of the full substitution of the curtain wall façade (including frame) of the school building. The selected façade is one of the three façades of the overall building. The building area subject to the refurbishment is organized as an open-space where students spend their free time during brakes. In order to compare the performances of the project developed solution, the two floors building façade are covered in part by EENSULATE module with VIGs and the rest by the same module installing standard TGU (Triple Glass Unit) in the frame. The EENSULATE module consists of two parts: the vision part (60%) covered with VIG and the spandrel part (opaque 40%) insulated with the innovative TCF foam. Thanks to the high insulation of the EENSULATE module, the new façade system significantly increases the energy efficiency of the building area under renovation ensuring an improved internal thermal comfort. One of the main requirements for the intervention was represented by the similarity of the proposed solution with respect to the already refurbished ones keeping the same visual appearance. This aspect has been respected thanks to the flexibility and adaptability of the EENSULATE modules developed in the project enhanced by the ad hoc profiles designed by FOCCHI as well as the small thickness of VIGs manufactured by BGTEC. This pilot represents the demonstration case of the main project results.

Monitoring phase

The pilot will be exploited to monitor the Eensulate VIG system performances in a real installation in comparison to a common low energy triple glass. In order to perform that relative characterization both the system will be monitored with thermal and irradiance sensors. A picture of the primary school facade is reported in Figure 1, with evidenced in red the Eensulate VIG system and in yellow the standard glass installed in a frame close to the Eensulate one. The main quantities to be monitored are:

  • Internal and external glass surface temperature
  • Indoor and outdoor air temperature
  • Heat flux through the glass
  • Visible external and internal radiation
  • Solar external and internal radiation.

Muzeum Miejskie Dzierżoniowa - Dzierżoniów, Poland

Pilot description

This house, built in 1897, originally belonged to Hermann Cohn, Cohn Gebrüder co-founder and one of the first mechanical weaving mill in Dzierżoniów. The building has been carried out many renovation and adaptation in order to arrange the available space for museum purposes. Preserved elements of the interior gradually returned to its former glory thanks to the conservation work carried out. Today the museum hosts permanent exhibitions, including cartographic collections and documents concerning Dzierżoniów and the surrounding area. A large collection of artefacts illustrates the development of the region since the late Paleolithic to modern times.

Intervention details

The foreseen intervention is the implementation of EENSULATE glass based on VIG (Vacuum Insulated Glass) technology in a selected number of museum windows. Being an historical building, the renovation works, including the ones related to the windows, are subject to several and severe restrictions to preserve its artistic value. For this reason, the implementation of VIG directly in the original windows minimise the impact of the intervention increasing their insulation capacity with a consequent benefit for the people inside the room. This kind of operation is possible thanks to the small thickness of the VIG (12.2 mm) and lightweight perfectly adaptable to the original windows increasing their performances without changing nether the materials (the window frame is the original one simply refurbished) nor the aesthetic aspect.

Monitoring phase

This pilot will be monitored to estimate relative glass thermal and optical transmittance performances, therefore two glass systems will be monitored: the one that includes the Eensulate system and the traditional one. The main quantities to be monitored are:

  • Internal and external glass surface temperature
  • Indoor and outdoor air temperature
  • Heat flux through the glass
  • Visible external and internal radiation
  • Solar external and internal radiation.

In addition, in the Dzierżoniowie Museum, the thermal comfort will be monitored. To this aim the following quantities will be measured:

  • Room mean radiant temperature
  • Relative humidity
  • Velocity of the air in the room.
