====== Renewable Energy Generation Overview ======

The building renewables consist of two main plants - a renewable energy plant and a co-generation plant. A part of the co-gen plant (the ORC turbine) provides input for the renewable energy plant.

Please see the other knowledgebase sections for further details on each aspect of the system.

===== Co-Generation Plant =====

Water is heating to approximately 200°C by 4x solar thermal collectors on the roof, that hot water is harnessed by the following systems (in cascading order) with the output water still being potable.

  * 180°C: Organic Rankine cycle Turbine. Max 10kW
  * 120°C: Evaporative Chiller: Cooling 19kW, Heating 60kW.
  * 60°C: Augment Building Hot Water Supply
  

===== Renewable Energy Plant =====

==== Inputs ====

  * Photovoltaic Cells. 20kWp
  * Organic Rankine cycle (ORC) turbine output from Co-Gen Plant. Max 10kW
  * Wind Turbine: Max 12kW
  * Hydrogen Fuel Cell: Max 10kW

==== Outputs ====

  * Power stored in 2x 50kWh flow-technology batteries.
  * Energy output to Building Microgrid (microgrid is not connected to the building main grid)
