The PN-EN 12101-6 standard defines six classes of pressure differential systems: A, B, C, D, E and F. A designer working with an expert should establish which class to use in a given building. Depending on the choice, certain system design criteria introduced by the standard must be met.
A properly set air handling unit contributes to the creation of intensive airflow and reducing the risk of infection inside buildings. What should we do with a ventilation system to support air purification?
Dampers are one of the main components of ventilation systems. When installed in the ducting, they make it possible to adjust and cut the airflow off. But how do we know the parameters of ventilation dampers?
In multi-storey buildings floors are divided into individual fire zones. One storey usually represents one fire zone.
The Smay Duct Systems (SDS for short) are used in mechanical smoke ventilation installations. They prove to be useful in various spaces within residential and office buildings, e.g. underground garages, escape routes, staircases, hallways, large-scale commercial buildings, shopping arcades and atria in shopping malls.
Industry 4.0 in the ventilation industry. How do smart factories connect people, machines and virtual reality?
By now, everyone working in the industry should be familiar with the term Industry 4.0. Many, however, mistakenly associate it mostly or exclusively with industrial robotisation, i.e. eliminating people from production processes.
V-Offices building is being constructed in Krakow. This project achieved a BREEAM Outstanding rating at design stage with a score of 90.57 %, to date the highest BREEAM certified score in Poland and Central and Eastern Europe. Completion date is planned for the first quarter of 2019.
Our pressurization systems by default are subject to automatic 24-h tests of key components. Such tests are carried out without any manual intervention. Such functionality allows to reduce necessity for periodic inspections e.g. weekly, monthly etc. Scope and frequency of maintenance works are limited to the yearly inspection when all measurements are taken to confirm proper functioning of the system.
How to avoid mistakes while installing regulators that could affect the further operation of the system?
Despite the growing awareness among designers and installers as to the operation of ventilation systems, still there are many cases of air flow regulators installed in a way that prevents their proper operation.
How should the construction industry meet the ever-increasing needs for better indoor environment conditions and optimised energy consumption? Innovative mechanical ventilation solutions prove to be helpful.
People spend approx. 90% of their time indoors, i.e. in an artificially created climate. Therefore, buildings and their technical equipment should be designed and erected so that to ensure favourable thermal conditions for their inhabitants.
In the previous issue of “Brawo”, in an interview with Mr. Marek Maj, the founder of the company, we talked about the first days of SMAY and its history. In this issue you are invited to join us in a travel even further back in time - to the very beginning of ventilation.
We are experts in creating safe escape routes. Our solutions work perfectly not only in new multi-storey buildings, but also in older buildings under renovation, with installations being adapted to new, more strict safety requirements.
Building Information Modelling (BIM) revolutionized traditional building design. In the 1990s and early 2000s drawing boards were replaced by digital CAD-type tools. We are now looking at a similar breakthrough as we enter the BIM era.
Nowadays it is standard practice that the central heating is adjustable and every heater is fitted with a thermostatic valve for adjusting heating to the variable heat demand in a given room.
The aim of the presentation was to present the results of research of a fire development in a multi-storey residential building, without corridors. The research was carried out on a specially created test stand in a 9-storey building. The research space included an apartment and an adjacent staircase. The research included several fire tests.
How to properly design a pressure differential system (PDS) on a staircase? This task is relatively simple in simple buildings. However, it is difficult in complex buildings, e.g. high-rise buildings or power plants.
Limited space for investment has made constructing underground garages as part of buildings increasingly popular in our country. In particular, this is true for large city centres, where the number of parking spots in the streets is smaller than the number of drivers looking for a parking space. As a result underground and multi-storey car parks are becoming more popular.
Stairwell smoke ventilation systems in medium-rise buildings – physical tests at a test facility in Sosnowiec under “Safe Evacuation” project
This paper discusses an extensive programme of tests and numerical analyses on vertical escape route smoke ventilation in multi-story buildings described on the project ...
Many civil structures in which a fire ventilation system needs to be fitted are non-standard, complex, or simply so large that events, whose impact on performance in smaller structures is negligible, must be taken into account. One of such structures is the railway tunnel of Nowa Łódź Fabryczna railway station.
Our company collaborates with technical universities on various research projects. One of the projects involved road tunnel research by the Silesian University of Technology conducted in Laliki, Śląskie province.
