Solar Decathlon China 2017-
Energy & Electricity - design, optimize and
integrate with the “green house”
Power production method:
Energy Demand analysis
Climate and weather influence
System design using PVsyst program
Optimization systems:
implant and integration
•
Design a solution for all electric and thermal energy needs
complied with local climate and competition constrains.
•
Analyze and design innovative optimization methods.
•
Implant and integrate the solutions to the designed
architecture and systems of the house.
Integration:
Mechanical systems: Data Logger, Smart Home,
Solar PV, Solar Thermal, Grey-water Recycling,
Bio-Gas, Greenhouse, Rain water collection, HVAC
Method: Integration according to system
infrastructure: Electrical, Water, Data.
Weekly and monthly meetings,
unified task management system and folders
Energy Modeling and Analysis:
Method: Manual Calculation,
Computerized Simulation: EnergyUI, Revit, Insight 360
Smart Home & Data Logger System
Solar tubes lighting
2-D tracking system
SE power optimizers and monitor
More methods been in use:
Cooling PV panels by rain water system
Tigi thermo-solar panels
Each optimize system was tested and analyzed by 3 criteria -
contribution to power production/saving, Value for money
and innovation.
Electric one line diagram
Method: combined and close
work with the architectures and
designers regarding all needs
and constrains.
