SIA "S plus" proposal for the energy supply of multi-apartment residential houses in the ECO-Trigeneration mode.

An apartment building is a large energy consumer, but it can also serve as an energy producer. In order to reduce a proportion of the fossil fuels in the energy balance for the buildings, SIA "S plus" offers a concept in which heat for the heating and hot water needs in the building is provided by means of a wastewater the heat recovery system. Indoor cooling is provided from a wastewater in free cooling mode. Electricity for...

SIA "S Plus" has developed a concept to improve the operation of biogas stations. Production of different types of energy within the Eco-Polygeneration cycle.

This concept involves integrating the heat recovery technology created by SIA "S Plus" (‘Device’) in the production cycle of biogas. Specifically, inside the biogas fermenter (Fig. 1), it is necessary maintain a temperature of 42oC, whereby the fermented matter heats up to approximately 40oC, becoming a warm, sludge-like substance (‘digestate’), which is then drained into the storage lagoon, and letter...
