Energy Simulation for Buildings

LEED AP or for that matter IGBC AP are generally dependent upon the Energy Simulations professionals who have been trained on various energy simulations model like eQUEST and EnergyPlus. Energy simulations is an expertise which gets perfected with lots of practice on models.

Today weather information for most of the locations/cities are available and files are freely downloadable over internet. The energy simulations is a methodical exercise. The first step is to define the building foot print or import the AUTOCAD drawing which will firm up the footprint of the building. The orientation of the building is also an important element to simulate energy consumption. The other steps which are involved relates to defining the complete description of the building, hourly scheduling of occupants, lighting, equipment, and thermostat settings. eQUEST is relatively easy to use as compared to EnergyPlus. eQUEST is predominantly used at the design stage for simplified models. EnergyPlus provides more accurate results as it handles very complex data. Simulation model which begins with developing a model of the buildings based on plans and specification assumes minimum level of efficiency, ASHRAE 90.1. Alternative models are then worked out based on energy conservation measures adopted and savings, payback period is calculated to work out viability of energy conservation measures.

 

Green BuildingsBlog Author extends services for Building Energy Simulation through the use of eQUEST and EnergyPlus models. Requirements can be emailed through the comments in our blog section.

The simplified heads under which the whole process of simulation can be broadly divided is as under:-

  1. Building Site Information and Weather Data
  2. Building Shell, Structure, Materials, and Shades
  3. Building Operations and Scheduling
  4. Internal Loads
  5. HVAC Equipment and Performance
  6. Utility Rates
  7. Economic Parameters
  8. HVAC Zoning

Energy simulation exercise requires heavy practice to enable the energy managers gain some sort of proficiency in both eQUEST as well as EnergyPlus.
