About

Hello! Myself Srijan Didwania, Building Energy Simulation and Analysis Specialist.

I have a very diverse experience in energy simulation ranging from existinge building calibration for retrofit projects, new construction projects with focus on optimizing costs and environmental impacts, certification and compliance modeling & development of tools and techniques to enhanse workflow. I also have some research experience under reputed research organizations.

June 2012 to June 2014

Centre for Advanced Research in Building Science and Energy, CEPT University, India
Research Assistant

• Simulation and analyses (using Energy Plus and GenOpt) for design of voluntary ‘Window Labeling Program in India’. The research is published in IBPSA Conference Proceedings.

• Case study for comparison of Radiant Cooling Systems with VAV systems with respect to energy consumption, installation cost and Life Cycle Cost for four climate zones of India, using EnergyPlus as the simulation tool. The research is published in ASHRAE Conference Proceedings.

• Developed an excel based tool to compare the Life Cycle Cost of two design alternatives with respect to envelope characteristics by integrating library of material properties, cost, and pre-simulated energy consumption data of various design combinations from EnergyPlus.

• Contributed to the development of Indian Version of COMFEN tool under US-India CBERD initiative in collaboration with ‘Lawrence Berkeley National Laboratory’.

• Worked on hygrothermal testing of materials and simulation tool ‘WUFI’ at ‘Oak Ridge National Laboratory’ to facilitate establishment of hygrothermal testing facility at CEPT University.

• Developed a ‘Comfort tool’ for representation of comfort conditions based on PMV and Adaptive model.

• Worked as part of Survey team (15 office buildings in 5 cities of India) for subjective thermal comfort assessment, to facilitate development of adaptive comfort model in Indian context.

• Energy simulations for ‘Residential baseline study in India’ (A CEPT and GBPN initiative).

• Comparison of low energy cooling systems like ‘Direct and In-direct Evaporative Cooling’, ‘Radiant Cooling’, ‘Dehumidification System’, ‘Displacement Ventilation’, and ‘UFAD’, using EnergyPlus.
