About Building Energy Modeling Methods

Building Energy Modeling is a simulation of his “life” during the billing period (usually 1 year). The building model is located at a specific geographical point with characteristic climatic conditions. The building is correctly oriented to the sides of the world. The model takes into account the actual surrounding shading. The model takes into account the functional of the object, the work schedule of people and equipment, load profiles, types and algorithms of the engineering systems.

Methods of energy modeling of buildings allow us to analyze the energy and economic component of energy consumption. The analysis is based on the simulation results of the annual maintenance cycle of the building. The results are information on the energy efficiency of the building.

Energy efficiency of a building is an important indicator affecting the cost of its operation.
When connecting to energy resources, the question of choosing a tariff is sometimes raised. As practice shows, saving is not always obvious when choosing more complex differentiated tariffs.
Based on the results of the energy model of the building, the influence of tariffs on the annual cost of energy resources is clearly visible. Choosing the right tariff leads to an increase in the energy saving of the building.

It is difficult to make an informed decision on the choice of a particular design solution in terms of energy efficiency of the building. For this, it is necessary to take into account a large number of factors that somehow affect the energy consumption of the system under consideration. Sometimes such influence is completely not obvious.

Energy efficiency can be affected by architectural features, geographical location, orientation, climatic features of the terrain, building functionality, type of equipment, timetables and load profiles.

Modeling allows to take into account a combination of all factors in assessing the effectiveness of measures to improve the energy efficiency of the building. Energy modeling provides a reliable picture of the degree of effectiveness of a solution. With this information, you can reasonably choose only those solutions that are truly energy efficient for the building in question.

In addition, having information on savings in monetary terms, it is no longer difficult to adequately assess the payback period of the chosen solution.

Energy modeling of buildings helps to solve a wide range of tasks, optimize energy consumption and achieve energy saving in the building, and, therefore, reduce unreasonable operating costs.
