Invited speakers:
Smart readiness of the buildings for operation
Iurii A. Tabunshchikov, President of ABOK, Professor, Doctor of Technical Sciences, Member of Russian Academy of Architecture and Building Sciences (RAASN), Fellow ASHRAE, Fellow REHVA, Corresponding member of VDI, Head of the Department "Engineering Equipment of Buildings and Structures", Moscow Architectural Institute (State Academy)
Only a building that is equipped with smart engineering systems to ensure a high quality of the living environment can be considered ready for operation. The modern market offers a lot of engineering equipment in terms of heating, ventilation, air conditioning, non-traditional renewable energy sources, water supply, etc. The task is to set the rating of smart readiness of the building for operation. Introduced a definition for a Smart building, Intelligent building and Thinking of building. In all cases, the level of smart readiness of the building for operation is determined by the indications of indicators – information characteristics that reflect the technical perfection of the object. The smart building readiness rating opens up a market for engineering equipment. At the same time, the smart readiness of the building for operation does not require significant capital expenditures. For example, in the village of Dudkino (New Moscow), the use of a system of engineering measures that ensure the smart readiness of the building for operation required an increase in capital expenditures by 4.5 %.

REHVA COVID-19 guidance for HVAC systems operation and reduction the spread of viral diseases in workplaces
Jarek Kurnitski, Professor of Energy Performance and Indoor Climate in Buildings, Tallinn University of Technology, Faculty of Civil Engineering
New evidence on SARS-CoV-2 airborne transmission has made ventilation measures the most important engineering controls in the infection control. While physical distancing is important to avoid a close contact, the risk of an aerosol concentration and cross-infection from 1.5 m onward from an infected person can be reduced with adequate ventilation and effective air distribution solutions. Three levels of guidance are discussed in the presentation: (1) how to operate HVAC and other building services in existing buildings right now during an epidemic; (2) how to conduct a risk assessment and assess the safety of different buildings and rooms; and (3) what would be more far-reaching actions to further reduce the spread of viral diseases in future in buildings with improved ventilation systems.
Similarities and differences between REHVA’s & ASHRAE’s COVID-19 guidance
Valérie Leprince, PHD, member AIVC COVID-19 working group & ASHRAE’s Epidemic task force
Ventilation is a major element in strategies for minimizing the risk of COVID propagation. REHVA and ASHRAE have developed guidelines taking into account evidence of aerosol-based transmission. This presentation will have a closer look at the similarities and differences between the guidelines by REHVA and ASHRAE
A novel way of determining the neutral plane in stack effect calculations for the Moscow climate.
Peter Simmonds, Ph.D., Fellow and Life Member ASHRAE, FIBPSA
The calculation of stack effect is still a confusing phenomenon in tall building design. Temperature, and thus air density differences between indoors and outdoors cause stack pressure differences that drive airflows across the building envelope; the stack effect is this buoyancy phenomenon. The building is then characterized by an effective stack height and neutral pressure level (NPL) or leakage distribution, as described in many handbooks. Once calculated, these parameters can be used in physical, single-zone models to estimate infiltration.
The origin of stack effect comes from hydrostatic pressure differentials between building interiors and exteriors. Due to interior space heating or cooling of a building, different temperatures establish between the inside and outside of the building and thus result in air density variation in between. For any building associated with leakage, a neutral pressure level (NPL) exists, i.e., where the indoor and outdoor hydrostatic pressure are equal. Consequently, different densities of air lead to different stack pressures, positive and negative, at different heights except NPL. Thus, a pressure difference establishes across the building envelop at the same height. The magnitude of the pressure difference (ΔP) at the height (H) is related to the height of NPL (HNPL) and the indoor (Ti) and outdoor (To) temperatures.
The real question is how the Neutral Plane derived and calculated, this paper will provide a novel way of accurately calculating the neutral plane specific to the relationship of the building envelope openings and internal openings such as elevator doors and staircases.

Presentation of the new edition of R NP "ABOK" 5.3.2-2020 "Calculation and selection of air distribution devices". Solemn presentation of certificates to developers and diplomas to participating companies
Marianna Brodach, Vice-President ABOK, Professor of the Moscow Architectural Institute (State Academy), Fellow REHVA
New recommendations and manuals of ABOK on the calculation and selection of air distribution devices as a tool for preventing the spread of coronavirus infection
Andrey Strongin, Candidate of Technical Sciences, Head of the Laboratory of NIISF RAASN, head of the working group on the development of Recommendations of R NP "ABOK" 5.3.2-2020 " Selection and calculation of air distribution devices»
Ventilation systems are an important engineering tool for controlling the spread of coronavirus infection. Indoor air distribution determines the final effect of ventilation and air conditioning systems. Optimization of the design of air distribution devices makes it possible to improve the sanitary and epidemiological situation in the premises, eliminate overfilling, overcooling, drafts, dirty areas, and reduce the cost of heat and electricity

European Union Green Deal – Consequences for the European heating industry and new technologies
Andreas Lücke, Hauptgeschäftsführer BDH Bundesverband der Deutschen Heizungsindustrie e.V.
The European Union Green Deal is the flagship of the new European Commission under the EC presidency Ursula von der Leyen. One part of the Green deal the European Commission published in September 2020 is a new target for the 2030 Greenhouse gas emissions reduction in comparison to 1990, to bring it up from 40 % to 55 %. The Green deal includes a strategy for a Renovation Wave for existing buildings with actions to switch fuels towards renewable heating solutions, install the most efficient energy products and appliances on renewable energy and integrate energy managements solutions in buildings.
The European people of the northern hemisphere use approximately 40 % of their energy consumption for space heating and the provision of hot water. Consequently, heating is by far the largest energy consuming sector in Europe and Asia. As Russia joined the Climate Agreement in September 2019 like the individual member states of the EU before, the participation in the climate protection process is also very important for Russia.
The presentation will illustrate the importance of the "heating market" particularly shown in the consumption of energy for space heating and hot water, also for ventilation and cooling in the EU. It will give an overview over the existing modern technologies for an energetic modernization of existing building as well as for new buildings, in particularly of the obsolete less efficiency installations to reach the ambitious climate targets. By explaining the benefits of new technologies like Fuel cells, hybrids and green gases combined with smart energy management systems the presentation will show the readiness of the European heating market to contribute to the targets of the reduction of CO2 emissions.
