Buildings are systems that involve various dynamic temperature processes that affect performance in energy of them. For example, the thermal response of the envelope (that is, the elements that separate the interior of the building from the exterior, such as the roof, windows, doors, or floor, etc. ), the variation of environmental conditions or the performance of air conditioning systems to changes in thermal load due to occupancy and lighting, among others. Building energy modeling uses numerical methods to solve equations that describe the interaction of such thermal processes, with the goal of predicting dynamic performance and end use of energy from buildings.
The main purpose of the energy modeling service is to support decision-making in the design process and achieve specific energy saving goals of each project, providing valuable information on the holistic behavior of the properties and systems of buildings . Among its development, it seeks to obtain the greatest benefit at the lowest cost from technologies and strategies for energy efficiency.
The service is tailored to the specific needs and phases of each project. In early design phases where passive strategies that impact the architectural design of buildings can be examined according to the location of the project and type of climate in the region, such as: orientation, sunlight, thermal insulation of construction systems, window options, aspect ratio between window and wall, natural ventilation, among others.
Likewise, in advanced stages of projects that seek to reduce thermal loads that impact the sizing, selection and energy consumption of HVAC equipment. In general, the service offers guides to improve the energy performance of buildings and their systems.
The energy modeling service is perfectly suited for buildings that are in the process of achieving environmental certifications such as LEED (Leadership in Energy and Environmental Design, for its acronym in English). Particularly in the prerequisite and credit corresponding to the minimum energy performance and optimization of energy performance. In this service, energy modeling predicts the energy consumption of the projected building and compares the savings with a base standard building to demonstrate the project’s level of compliance with the LEED requirements.
With the energy modeling service:
- Compliance with LEED requirements
- Support for building design
