Also called the Cathedral of the Exaltation of the Holy Cross, the Russian Orthodox Church built between 1863 and 1866 is located in Geneva. Of Russian Revival style, it welcomes Orthodox faithful of various origins.

The systematic and traditional use of incense and hundreds of candles during religious ceremonies had as a corollary a deposit of soot and dust on the paintings and icons that cover this church up to in the vault of the dome. Due to the presence of this soot, numerous and costly restorations had to be done. The object of our mandate was to find a solution that would allow to reduce these restoration works and their intervals.

After studying the existing situation, ERTE proposed the following solutions to address this problem:

  • The air heating system was maintained because the only one possible. Initially it was a forced-air heating system with a coal-fired boiler.
  • The basement, where the sanitary facilities, the library and the technical rooms are located, was extensively modified. Radiators were added as basic heating with ventilation as back-up for air hygiene and document preservation.
  • Separate technical rooms (boiler room and central ventilation) were created, whereas initially the janitor used to take his naps next to the air boiler with all the problems of small leaks and leakages of CO and CO2 that this entailed!
  • The heating and ventilation functions were completely separated, whereas in the past they were one element. The fresh air intake was enlarged, the old ventilation ducts were completely replaced and the openings in the vault were reopened.
  • The ventilation system consists of a pulsed-air monoblock with recycling and efficient filter sections. In the dome, we installed an exhaust fan that draws in exhaust air through a network of 12 flexible ducts through the 12 openings in the dome.
  • An intelligent MCR control in the central unit in the basement was installed. It is very simple for the user who has only a few buttons to operate on the first floor. The system heats up before the church service (full power), during (quiet power) and afterwards to “flush” and ventilate so that the soot-laden fumes escape as quickly as possible to the outside.
