Foundational design handbooks, technical manuals, and peer-reviewed chapters published in collaboration with apex institutions, establishing the scientific baseline for energy-conscious architecture in India.

• Handbook on Energy Conscious Buildings - J.K. Nayak and J.A. Prajapati

Prepared as a joint research project between IIT Bombay and the Solar Energy Centre of India, this handbook by J.K. Nayak and J.A. Prajapati is a practical guide to energy-conscious architecture.

It helps architects design high-performance, low-energy buildings through:

• Passive Design Principles: Strategies tailored to India's diverse climatic conditions.

• Technology Integration: Guidelines for blending renewable energy systems seamlessly into building designs.

• Practical Resources: Technical illustrations, real-world case studies, and reference data to streamline the design process.

•  Manual on Solar Passive Architecture - J.K. Nayak, R.Hazra, J.A. Prajapati

Developed through a joint research project between IIT Bombay and the Solar Energy Centre of India, this manual by J.K. Nayak, R. Hazra, and J.A. Prajapati serves as a concise guide to sustainable building.

It functions as a practical design primer for architects and students through:

• Essential Information: Core passive solar data delivered in a highly concise, accessible format.

• Seamless Integration: Practical insights designed to be built directly into the architectural design process.

• Targeted Learning: Structural guidance tailored specifically for both practicing professionals and academic study.

• Chapter on Solar Passive Architecture in Advances in Solar Energy - Vol 2, ed. Garg and Singh

This volume is concerned with the applications of solar energy and contains the following six chapters; solar heating of buildings (Active Systems), solar energy for industrial process heat, solar furnaces, solar thermomechanical power, solar refrigeration and air conditioning, passive solar house heating.

• Numerous articles and papers on sustainable architectural practices.
