A2PBA2PBEER– Affordable and Adaptable Public Buildings through Energy Efficient Retrofitting
Project Overview.
 Develop innovative technologies
 Develop a systemic energy efficient buildings’ retrofitting
methodology for Public buildings
 Apply a “kit-concept” to the technologies in order to deploy
adaptable and affordable solutions.
 Demonstrate and validate the methodology of retrofitting and
use of the developed kits at three demonstration sites.
 Replicability validated further with virtual sites.
 Implement and exploit a training programme to provide
training across Europe.

Building Envelope
 External super insulated façade retrofitting system
 Internal super insulated façade retrofitting system
Vacuum Insulation Panel (VIP)
Using a VIP core material of fumed silica (thermal
conductivity 0.023 W/m.K) and placed in a thin
metalized polymer laminate (providing vacuum, air
and vapour tightness ) and reduces its thermal
conductivity to 0.005W/m.K.

thickness (30 mm) + rubber (3+3 mm)
•PVC clip supporting VIP panels
INTERNAL FAÇADE
- VIP insulation (30mm) + rubber (3+3mm)
- A polythene vapour barrier (to remove the risk of
interstititial condensation within the system)
• additional PIR insulation
- Mineral wool insulation (40mm) incorporated within
• Supporting structure
the metal studs (additional acoustic and thermal
• L profile with 10mm thermal break

Reversible Window
•
Main issue of existing low emissivity windows:
low E coating is either on the outer (max. solar
gain, desirable in winter) or the inner side (min.
solar
gain,
desirable
in
summer)
•
Breakthrough: to develop a reversible window, so
that users can rotate the sash from winter to
summer position and vice versa to change the
position of low E coating to select the right
configuration.

Prototype
The innovative window concept is based on the idea of reversing sash in vertical or
horizontal positions through the central axis.
• Prototype dimensions 900x1400mm
• Wooden profiles thickness of 90mm.
