About me

Renjith Jayapalan Nair

I’m a doctoral researcher at Loughborough University, United Kingdom. My research focuses on developing a building design guide that would assist during the early stages of design of residential buildings which would exhibit high thermal and daylight performance. The guide is developed, in the first instance, for Kerala – one of the 29 States India where no measures are specified in the building codes - Kerala Municipality/Panchayath Building Code - to ensure energy efficiency in residential buildings. My research covers:

  • Climate analysis to classify the climate zones of Kerala. A new method of classification, based on Adaptive Thermal Comfort Model, was developed as part of the research.
  • Uncertainty and Sensitivity Analysis to understand the influence of different building design parameters on the thermal and daylight performance of buildings in the different Adaptive climate zones of Kerala.
  • Dynamic thermal modelling and Climate-Based Daylight Modelling to understand the thermal and daylight performance of buildings.
  • Web-developing/designing to present the building design guide.
  • Usability testing to understand the acceptability of the developed guide among policymakers and practitioners.

Research Interest

"The room is there for the human being – not the human being for the room." - El Lissitzky

  • Climate-based building design:
  • Indoor comfort is greatly influenced by the outdoor weather conditions, and the responsiveness of buildings to the prevailing local climate plays an important role if the dual aspects of occupant comfort and low energy demand are to be met. My primary research interest is to aid the design and construction of buildings that would exhibit hight thermal and daylight performance and are tailored for the respective climate zones. With this view, I have developed a building performance simulation based design guide for construction of buildings in the different climate zones of Kerala (India). This guide would help designers and architects during the early design stages for construction of buildings that would exhibit high thermal and daylight performance. Click here to access the guide.

  • Indoor Environment Quality in buildings:
  • The well being of occupants in a building is greatly influenced by the indoor environment quality. A number of factors such as thermal, visual, acoustic quality of indoor environment could greatly influes the comfort and well-being of occupants. I am interested in understanding and improving the indoor comfort conditions in buildings. In align with this intrest I had worked on understanding how the building design influences occupant thermal and visual comfort in different climatic condition. More information can be found here.

  • Low-cost low-energy eco-friendly homes:
  • Though my primary interest is research, I would also give my share in making the world a better place. I co-founded the start-up organisation EcoVolks. EcoVolks aims to construct low-cost, comfortable and energy efficient homes, which would exhibit a high thermal and daylight performance, across the State of Kerala (India).

    Research Impact

    Research impact

    My paper on the “Influence of climate on performance of buildings in Kerala” had inferred that the State of Kerala has regions with different climatic characteristics and that the designs for buildings should be tailored for the climate zones of Kerala. These results are in contrast to the observation of the National Building Code of India and the American Society of Heating, Refrigerating and Air-Conditioning Engineers.

    In 2018, Kerala witnessed the worst flood after 1924. In response, the Government of Kerala along with experts from the United Nation and the European Union assessed the the damages and losses and produced the Post Disaster Needs Assessment report. The results from paper were corroborated in the report.
