Smoke Extraction with Simon RWA Engines at the National Theatre
In 2005, it was decided that a building rehabilitation was necessary, and the rehabilitation work began in 2011.
The works lasted 3 years, and the rehabilitated National Theatre was inaugurated in November 2014.
Project Information – National Theatre
The investment required for the renovation of the National Theatre was 73 million euros. 23 million came from the Council of Europe Development Bank and 50 million euros from the Romanian Government.
The renovation carried out at the National Theatre was divided into 3 major projects:
- Left wing (Intercontinental)
- Right wing (Carol I Boulevard)
- Upper central wing
As part of the rehabilitation of the left wing (Intercontinental), KADRA provided 30 arm engines edition 2 – EA-KL²-t for swing door automation and 50 engines for window automation L35 (model also used at the National Library).
The 15 automatic swing doors use the arm engines edition 2 – EA-KL²-t to automatically open the doors in case of a fire. This mechanism has a dual role:
- Opening doors for the rapid and safe evacuation of people from the building.
- Creating a natural airflow intended to push smoke towards the smoke hatches in the roof and the smoke extraction windows mounted on the facade (operated by the Comunello LIWIN L35 engines provided by KADRA).
Fire Safety Measures – National Theatre
In case of a fire, both the automatic swing doors installed at the entrance (Intercontinental area) and the windows automated with L35 engines open automatically, even in the event of a power outage, being powered by 24V.
The solution used to create a natural airflow through the entrance swing doors was the only technical solution available due to the building’s design, which did not allow the implementation of large windows on the facade, a system of louvers, or similar mechanisms.
The fire safety regulations for constructions P 118 stipulate for smoke evacuation in case of fire (smoke extraction) in crowded halls, as well as in adjacent spaces accessible to the public, the following:
- the presence in the upper third of smoke extraction devices with automatic operation
- judicious placement and as uniform distribution as possible
- a total area of at least 1/100 of the hall area or ensuring smoke extraction through a mechanical system.
The door operating engines (located in the lower area of the facade) Simon RWA and the window operating engines Comunello LIWIN L35 are synchronized. In case of fire, the doors open automatically to allow fresh air entry, and the windows open automatically to allow smoke evacuation. The pressure difference created will ensure rapid smoke evacuation.
The system provided by KADRA at the National Theatre complies with the provisions of the P 118 regulations, which require, in the case of natural air evacuation by sweeping, the synchronization of smoke evacuation paths and fresh air introduction paths – when the evacuated air introduction (fresh air supply/compensating air) is done through the door, it will be equipped at its lower part with a grille whose opening will be commanded simultaneously with that of the hatch (smoke extraction window).
Solution Provider – National Theatre
The solution offered at the National Theatre simultaneously solves the problem of fresh air supply and emergency evacuation by using Simon RWA door engines.
The modernization of the National Theatre currently offers increased safety to individuals by complying with the fire safety regulations for constructions P 118. For the Intercontinental Area of the National Theatre, compliance with the P 118 regulations is achieved by using 30 arm engines edition 2 – EA-KL²-t for automatic swing doors and 50 engines for window automation Comunello Liwin L35 provided by KADRA.
The German company Simon RWA Systeme is a pioneer in smoke extraction and emergency evacuation solutions, offering advanced solutions worldwide since 1960. Simon RWA is available in Romania through KADRA.
Evacuation in case of fire and smoke extraction are two important elements for buildings. IGSU operating permits are granted in accordance with ensuring fire protection for individuals.
