This book includes topics that explore diverse and innovative aspects of architectural design, urban planning, infrastructure, and engineering. The "Values Trilogy Design Philosophy" emphasizes the harmonious integration of sustainability, cost-effectiveness, and artistic expression in architectural projects. "DIGIT-ACCESS" explores a digital gateway to enhance accessibility to heritage architectures. The influence of biomimicry and biophilia on sustainable urban planning is examined, along with the application of biomimetic approaches in smart city design and traditional architecture in Saudi Arabia's Asir region. An analytical study investigates zero-energy concepts in high-rise buildings, while another contrasts the thermal performance of various insulation systems in hot-desert climates. The role of interior design in fostering creativity and cultural enrichment in performance arts academies is highlighted, alongside an architectural appraisal of user perceptions toward Tamil Nadu Housing Board (TNHB) low-income housing schemes. In the realm of electrical, mechanical engineering, and fabrication, this book covers advanced topics such as reducing peak average power ratio in OFDM systems for cognitive radio, nonlinear buckling analyses of corrugated steel plate shear walls, and accelerated corrosion testing of carbon steel. The mechanical characteristics of sustainable rigid pavement using sintered fly ash aggregate are explored, as well as the impact of fiberglass reinforced concrete on sustainable design. Additional studies include the evaluation of water resistance in glass-modified concrete, the effects of laser treatment on waste poly(aramid) fiber for 3D printed composites, and the polymerization of copperas into polyferric sulfate for leachate treatment. Lastly, a thermogravimetric evaluation and kinetic study of pyrolysis in commercialized timber species in Peru provide insights into sustainable material behavior.
