COMFEN India is based on COMFEN originally developed by Lawrence Berkeley National Laboratory (LBNL), US Dept. of Energy. COMFEN India version is collaborative efforts between CEPT Uni. and LBNL as part of project titled US India Joint Centre for Building Energy Research and Development. (www.cberd.org) sponsored by UD Dept. of Energy and Indo-US Science and Technology Forum.
COMFEN is a simple single-zone facade analysis tool for commercial building based on EnergyPlus and Radiance simulation engine. COMFEN can be used to evaluate a range of façade configurations to understand the impact of design variables on building performance.
The Indian version for COMFEN (version 5.0.21) has construction schedules, glazing systems, façade options, occupancy, lighting, equipment and HVAC schedules - all customized to reflect day time and 24 hour operation of buildings in India as well as to suit Indian codes and compliances. It also has weather data of 60 Indian cities for simulation.

Expertise Required: 

No Specific Expertise requirements

Audience: 

Architects, MEP Engineers, Energy Analysts, Students

Input: 

Need specific scenarios by specifying the building type, geographic location, orientation, and window configuration. Users also specify size, shading, and thermal properties of the window along with other parameters (occupancy, lighting, equipment and HVAC schedules, etc.) required for energy and daylight simulation.

Output: 

Evaluation and comparison of a range of facade configurations in order to understand the impact of different design variables on facade performance (energy consumption, daylighting and glare analysis, cost calculation, etc.)

Strengths: 

COMFEN can help users pick the most energy-efficient and cost-effective window for a given application for Indian context. It calculates heating and cooling energy use and associated costs as well as peak heating and cooling demand for specific window products.
