General Information




     Energy modeling of buildings is a practice of evaluating the energy use of a building through simulating and accounting for the many energy related components.      




     The goal of energy modeling of buildings is to accurately predict the energy use of a building to either test the energy performance of the building with regards to an established standard, or to compare and contrast two buildings in order to find the resulting energy savings.     


Industries Served:

     All buildings that have significant utility or energy use benefit from energy modeling.   Not all energy efficient equipment or practices fit all situations.   Analysis through energy calculations are a useful way to predict savings and calculate payback.   Care should be taken to find the most worthwhile savings created in exchange for the typically higher up-front cost and effort.  


Role of Federal, State, or Governing Authority

     Often, building managers or new construction design teams are encouraged to install energy efficient equipment or implement energy saving strategies.    Encouragement comes in the form of potential for future energy savings, an abstract point system (LEED, Green Building Standard), region-wide mandates (e.g. NYS Executive Order 111), or financial incentives. If by definition, an energy efficiency or Energy Conservation Measure (EEM/ECM) generate savings, in many cases this savings do not justify the (unreasonably) high up front cost.    Incentives help to offset the high initial cost of equipment and to reduce the number of years that it will take for energy savings to break even with initial costs.

Problems with Energy Modeling of Buildings






     Classification of the different methods are diverse in their practice but generally subscribe to the goal of predicting energy use.   The choice between the different methods is primarily based on level of accuracy desired and what methods, codes, or standards a governing body requires the modeler to adhere to.
