We also participate in numerous research programs to determine long-term energy scenarios in the global economy. Our clients include major global energy companies, equipment manufacturers, industries, and governmental bodies.

Energy Modelling & Simulation is the virtual or computerized simulation of a building or complex that focuses on energy consumption, utility bills and life cycle costs of various energy-related items such as air conditioning, lights, and hot water. It is also used to evaluate the payback of green energy solutions like solar panels and photovoltaics, wind turbines and high-efficiency appliances. To understand energy modeling, it’s important to understand building simulation.

Building simulation is the process of using a computer to build a virtual replica of a building. In layman’s terms, the building is built from its component parts on a computer and a simulation is performed by taking that building through the weather conditions of an entire year. In a way, building simulation is a way to quantitatively predict the future and thus has considerable value. Building simulation is commonly divided into two categories: Load Design, and Energy-Analysis. The common phrase for building simulation when energy is involved is Energy-modeling.

Load Design is used to determine:

• Air conditioning loads (the amount of cooling/heating energy needed by space/system/building);
• Volumetric airflow requirements (the amount of air needed to cool/heat a space);
• Equipment capacities (since equipment may condition multiple spaces);
• Supply Temperatures;
• Hydronic Plant capacities (worst case simultaneous load);
• Similarities and differences between equipment options for heating and cooling a space.

Energy-Analysis or Energy-modelling is used to:

• Predict the monthly energy consumption and bills;
• Predict the annual energy cost;
• Annual CO2 emissions;
• Compare and contrast different efficiency options;
• Determine life cycle payback on various options.
