Water fittings are a necessary element of equipment
for building plumbing systems. One of the main technical characteristics of water fittings is their regulatory
capacity. Currently, valve heads with flat ceramic locking elements are widely
used in plumbing systems. Ceramic locking elements work with a high abrasion
resistant and without water leaks. Regulatory capacity of flat locking elements
depends on orifice shape.
The article discusses the dependences of carbon
monoxide (II) concentrations on the height of the building façade based on the
results of in situ tests with the goal of preventing the inflow of pollutants
into the ventilation system. Carbon oxide (II) may enter the premises when the
inlet ventilation system is working through the inlet chamber from external
sources of emission, i.e. vehicles and low and medium-power boilers in
the urban environment.

The article describes the concept of creating a
polyvalent heating system for a passive house situated on the premises of the
Institute of Technical Thermal Physics of the National Academy of Sciences of
Ukraine. A brief analysis of common heating systems used in the residential
sector, and public and industrial buildings is conducted. The authors describe the main stages of developing
the principal hydraulic circuit of a polyvalent heating system for a passive
house from renewable energy sources.

Municipal solid waste (MSW)
landfills located in regions of Russia with low temperatures and relatively low
rainfall averages are considered unpromising in terms of their biogas
potential; however, these claims have not been substantiated. Assessment of the
biogas potential of such landfills requires special field research for
analyzing biogas composition and emission speed, which could define the
processes taking place inside a landfill.
