Abstract

The paper devoted to indoor air quality providing in orthodox churches in Russia. Using the results of theoretical and experimental research made some practical recommendations for design and installation of ventilation systems in orthodox churches. Significant part of research deals with air and constructions humidity controls by reverse osmosis. It is reaffirmed that the rate of dehumidification is directly connected with the air exchange rates and operation of space heating devises in premises. It is very common to use natural ventilation in old churches. It is very easy to install and maintain, but still this way of indoor air conditions providing is absolutely not sustainable. And to avoid the leak of ventilation efficiency for different rooms it is recommended to provide mechanical supply and exhaust ventilation. Another significant issue for providing rapid wall dehumidification is properly operating space heating. It is noted that heating should be combined with an action of ventilation and electroosmotic drying.

Highlights

  • Russia is a very touristic country with permanently rising tourists flow in all year around

  • The most points of interest are connected with mid ages Russian history

  • Abnormal maintenance and decreased operation efficiency lead to emerging sick building syndrome with negative influence on indoor air [1] quality and constructions conditions

Summary

Introduction

Russia is a very touristic country with permanently rising tourists flow in all year around. The most points of interest are connected with mid ages Russian history. The significant part of historical heritage is traditions, people and facilities of Orthodox Christian Russian church. Physical condition and sustainable maintenance of churches is up to date issue for old Russian cities and places. These days significant investments and attention attracted into retrofitting of XVIII - XX centuries historically valuable facilities. The most damaged part of typical heritage facility is ventilation and heat supply systems. Abnormal maintenance and decreased operation efficiency lead to emerging sick building syndrome with negative influence on indoor air [1] quality and constructions conditions
