The peculiarities of formation of sustainable architectural environment using green photobioreactors

The subject of this research is the peculiarities of formation of sustainable architectural environment using green photobioreactors – a technical devices that ensures specific conditions for the life cycle of microalgae. In global practice, this direction is known as “Algaetecture”. The authors define “Algaetecture” as a set of measures and means for the formation of environmentally sustainable urban environment, based on the integration of green photobioreactor systems into the structure of open and closed urban spaces. The research demonstrated that the spatial characteristics of objects containing photobioreactor systems are directly associated with the conditions for the life cycle of microalgae. Modelling of the shape for enduring the life cycle of microalgae is one of the leading factors in the formation of volumetric planning characteristics of buildings, development of landscape design of the vicinity, and architectural solution of the photobioreactor systems themselves. As a result, the author determines the main methods of creating urban environment that maximize the efficiency of based on photobioreactors green systems that are integrated into the building. This includes: consideration of local climate peculiarities in development of spatial characteristics of the buildings, namely for redistribution of solar radiation; use of various techniques for the formation of multilayered, weather-adaptive façade envelopes and roofs of the buildings; ensuring the interface between the architecture of external photobioreactor systems and interior environment of the buildings for creating the inside light and heat comfort; formation of the vicinity open spaces and surfaces of the building that contains photobioreactors, as a unified system that regulates insolation and wind streams; combination of different photobioreactor systems and microalgae cultures, including in the one particular architectural object. Based on the acquires results, the author offers solutions for the volume, surfaces and territory of a building that includes photobioreactor systems, considering the specificity of the monsoon climate of Southern Primorye. The recommendations are elaborated on the development of the architecture of photobioreactor systems for the facades of buildings depending on their expansion into the main sectors of the horizon.
