Buildings are systems that involve various dynamic temperature processes that affect the energy performance of the building. For example, the thermal response of the building envelope (i.e., 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 employs numerical methods to solve the equations that describe the interaction of such thermal processes, with the objective of predicting the dynamic performance and final energy use of buildings.
The main purpose of the energy modeling service is to support decision making in the design process and to achieve specific energy savings goals for each project, providing valuable information on the holistic behavior of building properties and systems. Among its development, it seeks to obtain the greatest benefit at the lowest cost of 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 of the region, such as: orientation, sunlight, thermal insulation of building systems, window options, aspect ratio between window and wall, natural ventilation, among others.
Also, in advanced phases of projects where the aim is to reduce thermal loads that impact the sizing, selection and energy consumption of HVAC equipment. In general, the service offers guidelines to improve the energy performance of buildings and their systems.
The energy modeling service is ideally suited to buildings that are in the process of achieving environmental certifications such as LEED (Leadership in Energy and Environmental Design). Particularly in the prerequisite and credit for minimum energy performance and energy performance optimization. In this service, energy modeling predicts the projected building’s energy consumption and compares the savings to a baseline standard building to demonstrate the project’s level of compliance with LEED requirements.
