Transcript

  • 1. Where did it go ?
  • 2. Introduction: What is a building performance simulation program? 1
  • 3. A buildings is a complex thermodynamic object that accommodates constantly changing energy flows between the different thermal zones within the building and the outside.
  • 4. The two main components of the building energy simulation model are the building fabric and content (walls, floors, ceilings, occupants and equipment) and the plant components (HAVC equipment and other environmental control systems)
  • 5. Due to the complexity of a building model, computer simulations can analyze the effects of different ECMs (Energy Conservation Measures) and their complex interactions more efficiently, comprehensively and accurately that any other available method
  • 6. How and why did Building Performance Simulation (BPS) start? 2
  • 7. 1960’s US government involved in projects to evaluate the thermal environment in fallout shelters
  • 8. BPS tools evolving as a discipline producing a variety of BPS tools that are scientifically and internationally validated
  • 9. 1980’s several BPS tools developed to help architects perform early energy analysis and create more energy efficient and sustainable buildings
  • 10. 1990’s architects and designers got more encouraged to join the BPS field
  • 11. BPS tools address: energy consumption of buildings (cooling and heating demands), thermal comfort, natural lighting and ventilation
  • 12. Using BPS tools in the early design process began having an impact on energy performance and cost of buildings
  • 13. Do we really need BPS tools as architects? 3
  • 14. Most BPS tools are developed by technical researchers, building physicists or HVAC engineers
  • 15. BPS is not just a physical analysis but also a human, psychological and social discipline
  • 16. It involves man-computer interaction and human knowledge processing, while enriching human experience
  • 17. BPS tools improve the integration and alliances between engineers, architects and constructers to create realistically integrated projects together
  • 18. BPS tools are decision tools developed to help architects and building designers to predict and simulate quickly the building performance in early design stages
  • 19. It is a methodological decision tool that can help in determining technical design requirements Geometry Loads Results
  • 20. How to use a simulation program? (Energy Plus) 4
  • 21. We will be using EnergyPlus as the simulation engine EnergyPlus is the U.S. Departments of Energy’s 3rd generation dynamic building energy simulation engine for modeling building, heating, cooling, lighting, ventilating and other energy flows
  • 22. The program was developed during the nineties and is an amalgamation of the BLAST and DOE-2 simulation engines. Apart from energy use, the program can be used for load calculations and to model natural ventilation, photovoltaic systems, thermal comfort, water use, green roofs and other ECMs.
  • 23. Choosing a GUI for Energy Plus? Simulation engine Graphical User Interfaces
  • 24. Example: DK Integral Energy performance simulation program 5
  • 25.  DK Integral is a simulation tool for energy efficient and cost optimized buildings developed by the German physicist and engineer Siegfried Delzer  it calculates and simulates the energy performance of a building and evaluates it through graphs
  • 26. Start
  • 27. Entering Data
  • 28. Simulation
