Center for Advanced Research in Building Science and Energy

The Center for Advanced Research in Building Science and Energy (CARBSE) aims to provide an impetus to research and development in the area of energy and habitat. We rely on the tenets of building science to provide solutions for current and future challenges facing our communities and cities. Our multidisciplinary work aims to provide scientifically validated inputs towards policymaking, assist the development of design and technology, and facilitate knowledge-exchange for human capacity building.

CARBSE’s focus areas include passive and low energy building design, building material and construction characterization, occupant comfort, energy benchmarking of buildings and energy use modelling. We study buildings through the design phase, construction phase and their operational life. Our studies extend beyond individual buildings to the wider neighbourhood and city scales.

CARBSE houses state-of-the-art research infrastructure and employs highly trained and motivated domain specialists. Our research facilities are accredited by the National Accreditation Board for Laboratories (NABL). We also participate in International Round Robin inter-laboratory tests for various experiments and procedures on annual basis. We work with multiple leading industry, government, and non-government/not-for-profit organisations. The Center has designed and operates out of a Net Zero Energy Building (NZEB), a living laboratory that houses the Center’s activities and provides lessons in designing, constructing and operating a net-zero energy facility.

Our key initiatives include:

  • Performance evaluation of thermo-physical-optical properties of building materials and construction technologies
  • Occupant comfort studies and climate-specific thermal comfort models
  • Development and performance evaluation of low energy cooling technologies
  • Technical assistance for development and enforcement of building codes and construction

Yashkumar Shukla

Center Head and Principal Researcher

Dr. Yashkumar Shukla is Center Head and Principal Researcher at the Centre for Advanced Research in Building Science and Energy (CARBSE). He has more than seventeen years of research and consulting experience in high-performance buildings. He has led several ground-breaking research projects including low energy cooling and ventilation system in Indian residences, evaluation of innovative cooling technologies, and benchmarking of Indian buildings. He is also associated with the Master of Technology in Building Energy Performance (MBEP) program at the Faculty of Technology, CEPT University where he offers several courses and guides capstone projects.

Dr. Shukla's current research includes calibration of simulation models, smart grids, low cooling energy systems, performance characterization of the novel envelope and air conditioning systems, and development of the next-generation control algorithms. He is presently the team lead on the technical assistance program by Asian Development Bank on building disease resilient, smart, energy-efficient air conditioning systems in developing member countries.

Dr. Shukla possesses several professional certifications including certified measurements and verification professional (CMVP), Home energy rating system (HERS), GRIHA Trainer, and ECBC Master Trainer. He is an active member of the Indian Society of Heating Refrigerating Air conditioning Engineer (ISHRAE), the American Society of Heating Refrigerating Air conditioning Engineer (ASHRAE) and the International Building Performance Simulation Association (IBPSA) societies. He also holds several leadership positions in these societies and chairs technical committees at national and international forums.

Dr. Shukla joined CARBSE in July 2011 after working for seven years in building energy efficiency domain the USA and worked as the technical director at the centre till April 2021. His prior work experience also includes the execution of sophisticated building automation systems, conducting building energy audits, and providing technical support on demand-side management (DSM) programs for electric utilities throughout the USA. He has completed a Doctor of Philosophy from CEPT University, Ahmedabad; Master of Science in Mechanical Engineering from Texas A & M University, College Station; and a Bachelor of Engineering in Mechanical Engineering from Nirma Institute of Technology, Ahmedabad.
