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.

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.

Climate control systems for modern residential buildings: what to choose?
Aleksander Kolubkov, vice-president "ABOK", director PPF "AK",
"Black holes" in the design of ventilation for rooms with high sound insulation
Alexander Boganik, Ph.D., Technical Director of Acoustic Group, member of ABOK Premium category
Currently, the engineers of "ABOK" are working on the preparation of ABOK recommendations "Noise and vibration protection of engineering equipment in residential and public buildings". As part of the preparation of this document, not only the current norms, rules and recommendations are updated, but also new criteria for assessing the impact of engineering systems on achieving the required values of sound insulation of premises are being developed.
Non-standard solutions of ventilation systems
Alexey Milovanov, YUNK ENGINEERING LLC, member of the Presidium of ABOK
The classical ventilation system is a standardized engineering solution. The exceptions are technical specifications, reference literature and the implementation of premium class objects - made according to the requirements of ASHRAE standards (LEED certificate). They are confirmed by additional calculations that ensure: safety requirements, compliance with SanPiN standards and an increase in the comfort level of people staying in the premises.
The question of the energy capacity of the facilities is also open. Standard solutions comply with domestic standards for thermal protection of buildings, however, according to the terms of reference, it is often required to perform efficiency up to classes "A" and "A++"; up to the formation of energy modeling of buildings. Which allows you to redirect excess energy to other needs:
- Heat recovery, the removed air of general ventilation, for heating the air (including protection from threats in the form of harmful elements and waste air flows).
- Implementation of heat removal from the air cooling system - thermal energy is redirected to heating the hot water system (relevant in the warm and transitional period of the year).
- The use of variable and constant flow valves is also not common. The first ones are necessary for rooms with a variable number of visitors (meeting rooms or parking). The second, for multi-storey buildings, for optimal operation of the ventilation system in cold and warm periods of the year.
These technology solutions will reduce energy consumption. And electricity can be used for other needs, for gas stations, for street lighting, etc.
The situation on the market of industrial climate equipment

Innovative technologies in natural ventilation
Oleg Igonin, Co-founder of GERVENT Group, member of ABOK
Currently, there is a growing interest in natural ventilation: this is prompted by the problem of energy conservation and reducing the carbon footprint. The use of ventilation deflectors using wind energy to intensify air exchange makes it possible to abandon the use of electricity and, accordingly, reduce greenhouse gas emissions. Ventilation deflectors have a rich and, unfortunately, forgotten history. They have been used since the middle of the nineteenth century, as terminal devices for removing air from individual and collective channels of natural ventilation, individual and collective chimneys, channels for the release of gas combustion products, trunks of garbage chutes. Despite the obvious advantages, ventilation deflectors were rarely used in 1980-2010.
In the fundamental normative documents on standardization, there was also no place for requirements for ventilation deflectors. Today, this gap is fully compensated by the recommendations of ABOK "Calculation and selection of ventilation deflectors".
The use of digital building information models to optimize energy consumption in order to reduce the burden on the environment.

Гранты на капитальный ремонт многоквартирных домов предоставляются в Эстонии с 2010 года. В течение первого периода 2010-2014 годов в рамках эстонской программы грантов на реконструкцию KredEx было капитально отремонтировано около 700 многоквартирных домов. Оценка результатов комплексного обследования, включающего полевые измерения и мониторинг энергопотребления в отремонтированных зданиях, выявила множество проблем, связанных с вентиляцией. Система грантов была разработана таким образом, чтобы были установлены более строгие и подробные требования к системам вентиляции, а максимальная сумма гранта была увеличена с 35% до 40% от общей стоимости строительства проекта реконструкции. Эти новые требования включали в себя показатели вентиляции в помещении как для приточного/приточного, так и для вытяжного воздуха, а также требования к рекуперации тепла и предварительному нагреву приточного воздуха. Типовые технические решения были разработаны в виде типовых проектных чертежей и инструкций, чтобы упростить выполнение новых требований, включая установку рекуперации тепла и предотвращение тепловых мостов в изоляции ограждающей конструкции здания. В течение следующего периода 2015-2018 годов схема KredEx инвестировала в реконструкцию 102 млн евро. Последующее обследование показало, что многоквартирные дома были глубоко отремонтированы и хорошо проветривались, что привело к беспроигрышной ситуации. Экономический анализ показывает, что гранты, предоставляемые правительством, являются бюджетно-нейтральными из-за средней налоговой отдачи в размере 32% и дополнительного значительного создания рабочих мест, что вносит хороший вклад в экономику Эстонии. Домовладельцы получают выгоду за счет улучшения внутреннего климата и общего состояния имущества, а также увеличения стоимости недвижимости. С 2019 года схема реконструкции продолжалась с теми же техническими условиями, но гранты были разделены на 30% поддержки в крупных городах и 40-50% поддержки на периферии. На сегодняшний день отремонтировано около 3 000 многоквартирных домов, и в соответствии с долгосрочной стратегией Эстонии к 2050 году планируется отремонтировать все остальные многоквартирные дома, построенные до 2000 года, всего 14 000 зданий.
