IES Virtual Environment: A Powerful Tool for Building Performance Simulation
Building performance simulation is a process of using computer models to analyze and optimize various aspects of building design, such as energy efficiency, thermal comfort, daylighting, ventilation, and carbon emissions. Building performance simulation can help architects, engineers, contractors, and owners to make informed decisions that improve the environmental and economic performance of their projects.
One of the leading software solutions for building performance simulation is IES Virtual Environment (IESVE), developed by Integrated Environmental Solutions (IES). IESVE is a suite of integrated analysis tools that covers the entire building lifecycle, from schematic design to post-occupancy evaluation. IESVE allows users to create a single 3D model of the building and use it across different applications for various simulations and calculations.
Some of the key features and benefits of IESVE are:
It leverages the world-leading simulation engine (APACHE) to provide accurate and reliable results for heating and cooling loads, energy use, carbon emissions, water consumption, cost analysis, and comfort metrics.
It supports multiple building standards and compliance methodologies, such as LEED, ASHRAE 90.1, IECC, AIA 2030, NECB, Title 24, and more.
It enables cross-team collaboration and data exchange between different disciplines and software platforms, such as Revit, SketchUp, Rhino, AutoCAD, gbXML, IFC, etc.
It offers advanced capabilities for lighting design, airflow simulation (CFD), solar shading analysis, occupant behavior modeling, evacuation simulation, and more.
It provides interactive visualization and reporting tools to help users communicate and present their findings and recommendations.
IESVE is used by thousands of building design professionals around the globe to create high-performance buildings that are sustainable, healthy, and resilient. To learn more about IESVE and request a free trial or web demo, visit https://www.iesve.com/software/virtual-environment.
In this article, we will explore some of the applications and workflows of IESVE in more detail and show how they can help users achieve their design goals and challenges.
HVAC Loads, Sizing and Design
One of the most important aspects of building design is to ensure that the heating, ventilation and air conditioning (HVAC) system is properly sized and designed to meet the thermal loads and comfort requirements of the building. Over-sizing or under-sizing the HVAC system can lead to increased energy consumption, operational costs, maintenance issues, and occupant dissatisfaction.
IESVE provides a comprehensive solution for HVAC loads, sizing and design, based on the ASHRAE Heat Balance Method. Users can perform dynamic simulations of the building thermal performance and calculate the peak heating and cooling loads for each zone and system. Users can also design and optimize the HVAC system components, such as fans, pumps, coils, ducts, pipes, etc., using the built-in libraries or custom data. Users can compare different HVAC system types and configurations and evaluate their impact on energy use, carbon emissions, cost, and comfort.
Building Energy Modeling
Building energy modeling (BEM) is a process of simulating the annual energy consumption and performance of a building under various scenarios and conditions. BEM can help users to identify energy-saving opportunities, optimize design strategies, evaluate renewable energy options, and demonstrate compliance with building codes and standards.
IESVE offers a flexible and powerful platform for BEM, using the APACHE simulation engine. Users can model any type of building geometry, envelope, occupancy, schedule, lighting, equipment, plug loads, etc., using the 3D model or importing data from other sources. Users can also model any type of HVAC system and control strategy, using the ApacheHVAC application or importing data from other software tools. Users can run annual simulations and generate detailed reports on energy use, carbon emissions, water consumption, cost analysis, and comfort metrics. Users can also perform parametric analysis and sensitivity analysis to explore the effect of different design variables and parameters on the building performance. aa16f39245
