Rajan Rawal, Himani Pandya, Arjun Desai, Vishnu Vardhan, Yash Shukla, Sanyogita Manu, Agam Shah, Ami Abstract:
The paper presents the case study of a Net-Zero Energy Building (NZEB) located within the CEPT University
campus, Ahmedabad. It starts with a narration on design and construction and provides an overview of the
building envelope characteristics and operational strategies. Custom design and operation of the building
management system (BMS) in
order to synchronize the electrical consumption and generation using solar PV is
described. The paper analyses the energy consumption and generation in NZEB during 24 months of operation
(Jan-2017 to Dec-2018). Hourly end use energy consumption and generation data were analyzed to
understand the performance of the envelope and electro-mechanical systems. Along with energy consumption
analysis, the paper also includes the study of occupant comfort. The occupant comfort data was correlated
with the hourly outdoor weather data collected using an automated weather station installed at the NZEB. This
paper is an attempt to share the learnings in regard to the design, construction, operation, and maintenance of
the NZEB in India.
