3: Assessment of Energy Efficiency of an Existing Building based on GRIHA Framework

Assessing energy efficiency in buildings is crucial for reducing environmental impact, conserving resources, and saving costs. Buildings account for a significant portion of global energy consumption, and evaluating energy efficiency helps identify areas for improvement. This study focuses on key areas such as material efficiency, electrical efficiency, water efficiency and sustainable practices. Material efficiency is determined by Embodied Energy (EE) calculations, quantifying energy consumption across the lifecycle of material. Electrical efficiency is a critical aspect, encompassing lighting, HVAC, and electrical systems. Water efficiency is equally important, involving the installation of low-flow fixtures, rainwater harvesting, and greywater reuse systems. The GRIHA framework provides a comprehensive assessment tool, evaluating energy, water, and waste management. The ultimate goal of assessing energy efficiency is to enhance sustainability, reduce environmental impact, and promote eco-friendly building practices. In conclusion, assessing energy efficiency in buildings is vital for promoting sustainability, reducing energy consumption, and enhancing occupant comfort. It also helps building owners and managers to make a positive impact on the environment while benefiting from cost savings and improved market value.

9: Experimental investigation on plastic shrinkage study of self compacting concrete using recycled concrete aggregate

This study investigates the use of Recycled Concrete Aggregate (RCA) as a complete replacement for natural coarse aggregates in self-compacting concrete (SCC), with the objective of promoting sustainable construction practices. The research focuses on the preparation of SCC mixtures in which 100% of the natural coarse aggregates are replaced with RCA, sourced from crushed concrete blocks to ensure relevance to real-world recycling practices. A comprehensive experimental program was conducted, including slump and flow tests to assess the workability and self-compaction of the mixture, compressive strength tests to evaluate structural performance, and shrinkage tests to assess durability over time. The study compares the properties of SCC made entirely with RCA with conventional concrete, focusing on the impact of RCA on workability, strength, and shrinkage. Statistical analysis was performed to quantify the effects of RCA on concrete performance. The findings aim to provide information on whether complete replacement with RCA can produce SCC with strength and durability comparable to conventional concrete, while also offering environmental benefits, such as reducing landfill waste and conserving natural resources. This research contributes to the growing body of knowledge on the use of recycled materials in concrete and supports the transition to more sustainable construction methods.

17: Planning, Analysis and Design of a Smart Sustainable Mini Hospital

As healthcare needs worldwide continue to evolve, the importance of accessible and efficient medical services is gaining greater recognition. Larger hospitals frequently encounter challenges like overcrowding, long wait times, and resource strain, which underscores the need to explore alternative healthcare models. In this context, the mini hospital concept arises as a crucial solution. In this study the Planning,Analysis and Design and 3D visualisation of a Smart Sustainable Mini-Hospital at Valamboor, Ernakulam district is done using Autocad and ETABS. The nearest hospital is 18 km away from Valamboor. By constructing a mini hospital there provide immediate and essential medical services and inpatient care for the local community compliance with safety and operational standards. The planning is done using AutoCAD, the Analysis and Design is done using ETABS using the corresponding IS codes and KPBR rules and Design codes. And the 3D modelling is done using REVIT Software. The project prioritizes featuring energyefficient HVAC systems, solar panels, water-saving measures like rainwater harvesting and greywater recycling, and a comprehensive waste management system for responsible disposal and recycling.

23: Dual-layered Concrete ( DC ): Investigation into durability characteristics

This research introduces a novel approach to engineering Dual-layered Concrete (DC), aiming to enhance its mechanical performance and durability. The methodology involves crafting concrete specimens using conventional mix designs and specialized moulds to create a robust inner core and a protective outer mantle. A steel mesh acts as a barrier between the inner core and the outer mantle, enhancing durability and mechanical properties. Preliminary investigations have demonstrated controlled material segregation, with coarse aggregates predominantly occupying the core paste primarily filling the outer layer. These initial findings suggest significant improvements in mechanical properties, including enhanced ductility. This study aims to further explore the durability characteristics of the proposed Dual-layered Concrete (DC) specimens. A primary objective is to evaluate the durability performance of specimens prepared using three distinct concrete grades: M30, M35 and M40. The assessment will evaluate the concrete's durability in harsh environments, including acid, alkaline, sulphate attacks, and water absorption, comparing the durability of DC to conventional concrete. Additionally, the study will examine the concrete's microstructure, which significantly affects its durability properties. The findings of this research will provide valuable insights for optimizing dual-layered structures, enhancing their durability and applicability in various construction projects.
