Improvement of the safety of multi-floor housing

Phytofiltration is the most sustainable way to achieve a better quality of inlet air in buildings in a polluted environment. But they don’t take into account the biorhythms of plants and pollute the inlet air with CO2 during breathing only time. We collected and analysed data about the biorhythms of plants. As a result, a new bi-directional phytofilter was offered for cleaning and oxygenation of the inlet ventilation air, and also to protect the environment by cleaning the exhaust air from different pollutants. The device has spaces with shifted illumination rhythms and a valve system. A controller directs the inlet air to the space(s), where plants release CO2. The outlet air runs through other spaces. Literature data show that in the less favourable case, the CO2 and oxygen emissions are balanced per day without overall CO2 gain to the environment. When plants are growing, they sequestrate CO2 to catch greenhouse gas emissions. Either natural light, artificial light, or a combination of the two can be used. While the second option simply demands one plant metabolism type, the first option needs a combination of CAM metabolism and other plants

“…Green roofs and terraces are promising places for solving multiple tasks of different 1275 (2023) 012014 IOP Publishing doi:10.1088/1755-1315/1275/1/012014 2 branches [35][36][37][38][39][40][41]: heat loss recovery for planting (for rooftop greenhouses), additional heat insulation, optimized logistics, increasing pollinator populations, avoiding pests that cannot climb/fly at the corresponding altitude, etc. Previous authors' research [37][38][39][40][41][42] shows significant thermotechnical and sun-protective improvement. Also, this avoids the necessity of additional environmental protection, such as protective forest plantations [43].…”

Simulation of Illumination and Wind Conditions for Green and Fed Cities Using CFD Software

To avoid ecological catastrophe, most cities are moving toward green building. The critical component is greening – conventional and green structures. Urban agriculture is a very prospective direction. Green roofs, terraces, and rooftop greenhouses are the most promising places for growing. This solves multiple tasks: heat loss recovery for planting (for rooftop greenhouses), additional thermal insulation, optimized logistics, increasing pollinator populations, avoiding pests, etc. In different-height districts, there are problems with natural illumination and winds. No good urban wind theory has been developed. The winds can be simulated in CFD software using a 3D model of a district. Most of the software can simulate solar radiation for thermotechnical calculations only. It should be simulated in other special software. The approach to calculating solar radiation is proposed using CFD software without additional needs. The unique "integrator" material should be added to the engineering database. Its thermotechnical properties can be set to obtain a temperature numerically equal to the exciting parameter. Application is shown in an example of a different-height building with a green roof. The results show areas most favorable for growing photophilous and shade-tolerant plants and placing cleaning and phytoncidal plants for maximum air quality in stagnation zones.

“…Green structures [30] are an effective alternative, which can compensate for the lack of ground areas. Our researches show that green structures and indoor and outdoor greening can effectively solve different technical problems [31][32][33][34][35][36][37]. To sequestrate carbon dioxide emissions enough, we should properly design them using carbon dioxide sequestration.…”

Capturing Carbon Dioxide from Human-Driven Vehicles by Green Structures for Carbon Neutrality

2022

For carbon neutrality of cities, we should compensate carbon dioxide gains from vehicles. Human-driven ones are not carbon-free because cyclists perform hard work. Green roofs are an adequate carbon-capturing facility, especially for the dense building. We used the previous author’s data for carbon dioxide sequestration of them. The carbon dioxide gained from a cyclist is calculated using aggregated indicators for hard work and rest. Also, the experimental data for a cyclist on an exercise bike is used as an alternative. For recumbent bicycles, drag is 0.2÷0.3 of drag for classical ones. This allows estimation of the carbon dioxide gain for this promising technology. The results show that road bicycles require only 4.4 m2 of extensive and 1.37 m2 of intensive green roofs per cyclist. Recumbent bicycles need two-time fewer areas. Electric public conveyances and cars require one-two order of magnitude more area.
