In general, the content of energy simulations conducted by green consultants in Vietnam is based on MEP design data performed by popular MEP units, they only design to machine capacity, not project efficiency. or energy consumption. But the calculations are usually done in a simple way, mainly based on the rule of thumb, in the form of 220-250 W/m2 for office buildings. With this approach, the interpretation of LEED's energy criteria is difficult, and the system cost is high. Therefore, the current popular understanding in Vietnam is that green buildings are synonymous with increased investment costs.

Different from the above method, Edeec performs simulations to search for deep optimization, especially in terms of reasonable power allocation, considers operating factors in detail, understands how the HVAC system operates in coordination with other factors. different systems from which to provide detailed design data for the MEP consultant to deploy. At the same time, provide the work operation requirements for the BMS supplier to perform the programming.
