Building Energy Modeling

Building energy modeling (BEM) is a process that predicts a building's energy consumption and performance through numerical simulations. A virtual twin is created using inputs such as architecture, climate data, building envelope, system efficiencies, and usage scenarios. This modeling improves energy efficiency by making design decisions data-driven.

Influence at the Design Start

Energy modeling at an early stage allows for the validation of cost-effective improvements; optimization can be achieved without requiring significant interventions in construction costs. According to some studies, significant energy saving potential can be achieved with early modeling. Ecowa optimizes decision points by integrating this modeling from the concept design phase onwards.

Performance Simulation & Calibration

During the modeling process, systems such as HVAC, lighting, shading, and heat transfer are included in the simulations. After the model is completed, it is calibrated with real field data, and performance deviations are corrected. Ecowa coordinates both the modeling and calibration steps; this ensures that the simulation yields results closer to real life.

Cost-Benefit Analysis

Based on the energy model results, different scenarios (additional insulation, system modifications, etc.) can be compared. These analyses are used to balance investment costs with operating savings.

Certification Support

Many certification programs and energy regulations consider energy modeling a mandatory criterion. Ecowa reports the modeling results in accordance with certification criteria and provides verifiable outputs.

Continuous Monitoring & Performance Optimization

Modeling is a starting point; performance is monitored throughout the operational process using energy monitoring systems. Anomalies are compared with the model reference, and optimization suggestions are developed.
