eQUEST
eQUEST (Quick Energy Simulation Tool) is a comprehensive, yet user-friendly software tool designed for energy modeling of buildings. Here's a detailed look into its functionality, history, and significance:
Overview
eQUEST is developed by James J. Hirsch & Associates, known for their work in building energy simulation. It provides a simplified approach to energy analysis, making it accessible to architects, engineers, and building designers who might not have extensive experience with detailed simulation tools.
Key Features
- Graphical User Interface (GUI): eQUEST's wizard-driven interface guides users through the energy modeling process, simplifying the input of building design data.
- DOE-2 Engine: At its core, eQUEST uses the DOE-2 simulation engine, which calculates hourly energy use and cost for a year of operation, based on detailed building physics.
- Building Creation Wizard: This feature allows users to quickly define building geometry, construction materials, HVAC systems, and schedules, reducing the complexity of data entry.
- Parametric Runs: Users can perform multiple simulation runs with different parameters to analyze the impact of various design changes.
- Detailed Reports: eQUEST generates comprehensive reports that include energy consumption, utility costs, and environmental impact, aiding in decision-making for energy-efficient design.
History
The development of eQUEST began in the late 1990s, with the aim of simplifying the use of DOE-2 for building energy simulation. Here are some key milestones:
- Initial Release: eQUEST was first released in 1999, offering an easier way to utilize the capabilities of DOE-2 without the steep learning curve associated with the original software.
- Updates and Enhancements: Over the years, eQUEST has seen several updates to incorporate new technologies, building standards, and user feedback to improve functionality and user experience.
- Recognition: eQUEST has been recognized by the U.S. Department of Energy (DOE) and other energy efficiency organizations for its contribution to reducing building energy consumption through better design practices.
Context
eQUEST plays a critical role in:
- Energy Efficiency: It aids in achieving compliance with energy codes and standards, like ASHRAE 90.1, by allowing designers to model and optimize energy performance.
- Green Building Certification: eQUEST is often used in preparing documentation for certifications like LEED, where energy modeling is crucial for earning points.
- Research and Education: It serves as an educational tool in universities and research institutions to teach energy modeling principles and practices.
