Abstract -This study explores the integration of Archimedes Screw Turbines for micro-hydropower generation in urban high-rise buildings. With an effective head of 3.96 meters and a discharge rate of 0.0547 cubic feet per second, the system demonstrates strong feasibility for rainwater energy conversion. Optimized screw design, including a 6.94-meter length at a 35° inclination, a diameter ratio of 0.5–0.6, and a blade pitch of 24.3 cm, ensures efficient water conveyance and structural stability. The turbine operates at 146.69 RPM with an efficiency of 71.2%, achieving stable power output. This research highlights the potential of rainwater-driven micro-hydro systems as a sustainable energy solution, complementing wind sources. This research work is more efficient and self-sustaining renewable energy models in urban environments andsustainable power generation.

Enhancing energy generation in densely populated areas, this model represents a viable and scalable solution for improving building energy efficiency and advancing renewable energy adoption in smart cities.

2. PROBLEM DEFINITION The objective is to design an Archimedes screw-based hydraulic turbine and an Archimedes screw wind turbine to generate renewable energy for a three-story building with a total area of 3,000 square feet. The hydraulic turbine will utilize rainwater runoff to produce electricity, while the wind turbine will harness wind energy, ensuring efficient power generation within an urban setting. This dual-energy system aims to enhance sustainability by optimizing energy production in limited spaces, making it a viable solution for urban renewable energy applications.

1. INTRODUCTION

As cities strive for sustainable energy solutions, integrating wind and rainwater energy offers a promising pathway. This research introduces an innovative method for generating electricity in high-rise buildings by harnessing both wind and rainwater as complementary renewable energy sources. The proposed system combines a Liam F1 mini wind turbine—renowned for its efficiency in urban environments—with an Archimedes screw-based hydraulic turbine to effectively convert rainwater runoff into usable energy.

Urban areas often struggle with inconsistent wind patterns and space constraints, limiting the feasibility of large-scale renewable energy installations. The vertical axis wind turbine (VAWT) design is particularly wellsuited for high-rise buildings, as it efficiently captures wind from multiple directions and operates effectively at lower wind speeds typical of urban settings. Simultaneously, rainwater—an often underutilized resource—is channeled through an Archimedes screw mechanism to generate supplemental power.

4.STUDY OF EXISTING ENERGY GENERATION SYSTEMS Wind Energy Systems – Traditional horizontal-axis wind turbines (HAWTs) are widely used but are inefficient in urban areas due to inconsistent wind patterns. Verticalaxis wind turbines (VAWTs) offer better adaptability in cities by capturing wind from multiple directions and operating at lower wind speeds. Rainwater-Based Energy Systems – Existing rainwater harvesting systems primarily focus on water conservation rather than energy generation. While some large-scale
