VI International Congress AirVent-2023

«Challenges of safe microclimate in a changing world»

Within the framework of the international exhibition

AirVent Moscow 2023

February 14, 2023

10:30 – 12:00 13:30 - 18:00

Crocus Expo, Moscow



The Congress will combine two formats: offline on the territory of the exhibition and online on the АВОК webinar platform

Working languages: Russian and English with simultaneous translation.


On behalf of the organizers, it is with great pleasure that I invite you to

VI International Ventilation Congress AirVent!


Congress organizers:



Chairman of the Organizing Committee: Marianna Brodach, Vice-President of ABOK, Professor of the Moscow Architectural Institute (State Academy) brodatch@abok.ru

Conference participants: architects, design engineers and technical service specialists in the field of design, construction and operation of buildings for various purposes.

We invite specialists to participate in a wide range of issues related to the main topic of AirVent-2023 «Challenges of safe microclimate in a changing world»

Topics: changes in the market of climate equipment, environmental safety, new technologies and strategies for ventilation, heating and heat supply in a changing world for buildings with low energy consumption, buildings with zero emissions, as well as buildings with a high level of comfort and IAQ. 

Climate change and the transition to carbon neutrality remain at the center of many countries' policies and research programs. The construction sector plays a crucial role in achieving these goals, given the carbon emissions associated with the construction and operation of buildings and its potential to improve energy efficiency. At the same time, changes in the climate equipment market have demonstrated the need to develop the production of domestic equipment to ensure high indoor air quality (IAQ) and ventilation in our buildings. Solving these problems requires the transformation of the existing construction fund and the market of climate equipment, which will improve the IAQ indicators and reduce the environmental impact. Ventilation is a key tool in solving the problem of decarbonization of the construction industry, however, automation and digitalization of building engineering systems are of great importance for ensuring a safe microclimate.

AirVent-2023 offers designers, engineers, architects and manufacturers of engineering equipment a platform for the dissemination of technical information, discussion of new ideas, advanced developments and trends in the field of engineering equipment of buildings of the future. The congress will be attended by the world's leading experts.

On behalf of the organizers, we invite you to join AirVent-2023 to share your latest ideas and make new friends and like-minded people. Your contribution will be important for the success of AirVent-2023 and will be a memorable event for all our participants. 

Marianna Brodach, Vice-President of "ABOK", Professor of the Moscow Architectural Institute (State Academy), Chairman of the organizing committee

Pressure relationships in Supertall and MegaTall buildings

Peter Simmonds, Ph.D., Fellow and Life Member ASHRAE, FIBPSA

Most load calculations assume a simple air change rate of infiltration, but this does not take into effect the climate dynamics of tall buildings and the pressure relationships between elevator and stair shafts that can cause infiltration/exfiltration through a building's envelope. Facades are tested for acceptable leakage rates at pressure differentials across the façade. Usually, these tests are carried out to ensure there is no precipitation leakage into the building, but how accurate is the determined pressure differential, and what internal pressures drive the pressure differentials?

This paper illustrates the actual pressures in elevator and stair shafts and the relationship to the exterior under dynamic conditions. Traditionally we understand that external pressure is both air pressure and wind pressure at different heights of tall buildings, we also acknowledge that wind pressure is both windward and leeward and therefore this paper will determine air flow rates and directions (infiltration or exfiltration) through the façade and how the determined airflow rate will affect the load calculations?

This paper will benefit Architects, Engineers, and Contractors involved in the design and construction of Tall, Supertall, and mega tall buildings and will enable engineers to accurately determine Cooling and Heating loads as well as the energy predictions for tall buildings.

This novel paper explores the nuances of the ambient climate on tall buildings and the effects on the performance of the building and can also be used by Architects and Façade fabricators in determining the true infiltration and exfiltration characteristics of a building's façade.

KEYWORDS : Curtain Wall, Façade Theory or Philosophy, High Performance Façade, Air infiltration, Energy efficiency



Rethinking the Strategy of Building Indoor Environment for Carbon Neutralization

Professor Yingxin ZHU,Tsinghua  University, is one of the leading experts in  the field of indoor environment in China,academy fellow of ISIAQ (International Society of Indoor Air Quality and Climate), associate editor of international journal INDOOR AIR, chair of the National Steering Committee for Higher Education in HVAC Engineering. 

Global energy consumption for building operation accounts for 30% of the world's total energy consumption, of which HVAC energy consumption accounts for more than 40%. Therefore, the carbon emission generated by maintaining indoor thermal environment is a non-negligible amount. To achieve carbon neutrality, any country must find ways to reduce the carbon emissions generated by the operation of HVAC systems and equipment.

There are basically two strategies to reduce the carbon emissions of building operation. One is to reduce the carbon emissions of energy supply side, including improving the energy efficiency of HVAC system and using zero-carbon energy. The second is to reduce the carbon emissions of the building demand side. The air conditioning system invented by Willis Carrier for the printing plant in 1902 aims to control the temperature and humidity of the entire indoor space of the workshop, and the subsequent HVAC systems also follow this principle. The current indoor thermal environment standards of various countries and ISO 7730 are aimed at controlling indoor thermal parameters within a tight range. This traditional strategy is actually the main factor leading to high energy consumption in buildings.

The following issues are discussed in this presentation: 

Can controlling indoor thermal parameters within a tight range ensure high occupant’s comfort? What is real comfort environment? Is it healthy to stay in a thermal neutral environment for a long time? 

Finally, it is pointed out that the concept of the whole indoor space control must be changed, and accurate services should be provided to meet the needs of indoor objects. A dynamic thermal environment close to the mild natural environment will provide better health and comfort. However, achieving these goals requires cross-disciplinary technological progress and cooperation.
