Pilot Studies

Four pilot studies will be carried out as part of the HIT2GAP Project. These are in Spain, France, Ireland and Poland. For more information regarding the HIT2GAP demonstration buildings, contact Piotr Dymarski, Mostostal.


  • Establish reference (base year) energy performance.
  • Gather data from energy bills related to the base year.
  • Compare the designed (simulated) and real energy performance of each pilot.
  • Survey user preferences.


The Spanish pilot study is focused on a building in San Sebastian containing offices and laboratories.

The building has photovoltaic (PV) panels and a BMS which controls the lighting and HVAC system.

This 6200 square-meter building, completed in 2009, is used to fabricate nanscale materials and to characterise their properties with high sensitivity.  It provides an indoor environment which is free from electromagnetic interference with an ultra low level of vibration.  The building includes a large clean-room (300 square metres) in which air purity is closely monitored.  It also includes an electron microscopy laboratory, nano-optics laboratories, nano-bio facilities and advanced equipment for nano-fabrication and characterisation.

Giroa are responsible for this demonstration.


Challenger, a large office complex on the outskirts of Paris is to be used as one of the pilot demonstration buildings for the HIT2GAP project.

The Challenger building is situated at the headquarters of Bouygues Construction located in Saint Quentin en Yvelines near Versailles in France and is one of the demonstration sites of the HIT2GAP project.  The site comprises 3 main office buildings with a total area of 67,000 m2, it has achieved triple certification: LEED, BREEAM and HQE and contains a large set of renewable energy technologies including 24,515 m2 of photovoltaic and dual solar panels as well as ground source heat pumps connected to geothermal wet and dry probes.

The BMS operates lighting, HVAC, hot and cold water and technical alarms in the building

Bouygues Energies & Services are the project partners responsible for this pilot study.


The demonstration building in Poland is located in Warsaw and is a public building which also contains offices.

There are no renewable technologies in this building. The BMS controls lighting and HVAC.

This 12406 square-metre building, completed in 2014 is a 4-storey public building containing offices and an underground car park.

Mostostal are the contacts for this demonstration.


The Irish pilot study is focused on a building in Galway containing offices, lecture theatres and laboratories.

The building has a Climate wall with top-vented stack control and solar control via blinds, lighting systems and a  BMS which controls the HVAC system.

This 14250 square-metre building is a 4-storey engineering teaching and research building which was completed in 2011.  It includes 400 classrooms, some large lecture theatres and 25 breakout zones.  The building has rainwater harvesting, a biomass boiler, grass roofs and a variety of other green technologies.

Cylon Controls are responsible for this demonstration.
