window is installed, then users can rotate the sash from a winter to summer position and vice versa to change the position of the low-e coating to the most suitable configuration. Windows, window frames, glazing and window closing mechanisms that utilise a unique closing mechanism have been developed. This allows the window sash to be turned around by 180 degrees and locked in the opposite position. Each window is fitted with an inside and external pane of glass which permit various amounts of solar radiation into the building at different times of the year. Each window can be regulated and controlled manually or electronically.
“In existing buildings, combined heat and power systems may already be installed, but these systems often fall short in efficiency”
Smart lighting The smart lighting component of the project is a combination of the solar lighting technologies
provided by Parans and
Toshiba’s LEDs and intelligent systems. Smart lighting systems aim to reduce the use of electric lighting in the buildings by introducing natural lighting and adjusting artificial lighting depending on available natural lighting. Sunlight collectors capture and
concentrate solar radiation to be introduced in the building. The collector tracks the sun by means of an algorithm with the local solar path and redirects it to the building by fibre optic cables. The solar collectors can be mounted on roofs or facades and can track the sun over the full day. The combination of solar collectors and LEDs with diffusers under the control of an intelligent lighting system greatly reduces the energy expended on lighting.
Thermal network In existing buildings, combined heat and power systems may already be installed, but these systems often fall short in efficiency. In order to employ the dual thermal approach it is necessary to install

absorption/adsorption machines at building level and solar thermal systems with short- term storage. This will maximise the use of available free solar energy. In traditional buildings, the thermal
energy extracted from the district heating system operates in a single direction and therefore any heat produced by solar energy during periods of

low demand is not
distributed efficiently to other buildings within the district. Bi-directionality will optimise solar production and provide efficient storage capacity at district level, enabling the centralisation of all the individual solar and storage installations into one. This proposed system will be flexible and modular, both at building and district level, and can be easily replicated into many types of buildings.
The demonstration districts A2PBEER will demonstrate that its process is replicable for different building uses and climates by its implementation in three real demo districts. One of these demonstration sites is vocational school in Ankara. The building envelope will be retrofitted with the new external superinsulated system. Some of the west- oriented windows will be replaced with reversible windows, while high- performance low-e coat windows will replace the rest. The internal lighting will be replaced with a smart lighting system, combining natural light, LED systems and an intelligent control over the entire occupied area. A thermal solar collector system will be installed within the building to produce the required water temperatures for the hot water supply in the heating system and for satisfactory cooling performance for the building during the heating season. Centralised hybrid ventilation with heat recovery system will be installed with optimised economiser operation for free cooling. Cooling will be provided by the installation of a building dual thermal substation supplied by the on-site solar collector system and the district-heating network. Short-term thermal storage will be installed in order to improve the design and performance, of the solar collector system as well as optimising its integration with the building thermal substation. Similar demonstrations will be taking the Technology and Maritime
place at
Museum in Malmo and a group of administration buildings in the University of Bilbao, with technologies suited to the climate being retrofitted as applicable. It is
Project Objective: A2PBEER is developing, demonstrating and evaluating energy efficient retrofitting solution packages and a systemic approach in order to reduce public buildings’ energy consumption by more than 50% in 3 demo buildings/districts located in Spain, Turkey and Sweden. Innovative, affordable and adaptable technologies and a methodology is exploited using a support guide toolkit and training across Europe.

expected that the A2PBEER demonstrations will prove that is technically feasible and cost effective to reduce the current energy consumption of existing public buildings and thus make it possible to significantly reduce energy consumption within the EU. The industrial partners involved in the project will be able to increase their profits by marketing their innovative solutions in the near future, with the advantage of high market readiness of the new solutions.
