The project objective is to upgrade the ESB depot in Athlone, Co Westmeath, into a B1 BRE rated facility. Constructed in 1999, this two-story structure, characterized by its linear form and precise structural grid, is the focus of an extensive refurbishment project aimed at enhancing its energy efficiency and operational sustainability. The core objective of this project is to significantly reduce the building's energy consumption and carbon footprint through a series of targeted interventions. This includes the replacement of all external fenestrations with advanced triple-glazed units designed to achieve a minimum U-value of 1.2, thereby reducing heat loss and improving thermal insulation. The project also aims to enhance the building's air tightness to a level where air exchange is less than 25m3/h/m2, a critical factor in maintaining energy efficiency. The upgrade of the existing Salto security system, alongside the structural and aesthetic enhancements, exemplifies the integration of technology in modernizing infrastructure. The demolition and replacement of specific architectural elements, such as the timber façade at the entrance, underscore the endeavor’s commitment to utilizing durable and energy-efficient materials. The project also requires the planned reinforcement of the roof structure to support photovoltaic (PV) panels. This not only demonstrates a move towards renewable energy sources but also aligns with ESBs Net Zero 2040 sustainability targets. The inclusion of infrastructure for double electric vehicle (EV) chargers further emphasizes the project's role in promoting eco-friendly transportation solutions. This project is not limited to structural and technological upgrades; it also encompasses a comprehensive approach to fire safety and emergency preparedness. The replacement and upgrade of all existing fire doors, along with fire remediation works across all service penetrations, are integral to ensuring the building's compliance with fire safety standards. The project's approach to creating a safer environment through scientific methods and materials, such as the encasement of exposed steel elements for fireproofing, is exemplary of its holistic view towards refurbishment. By aiming to achieve a B1 BRE rating, the project not only seeks to enhance the building's energy performance but also contributes to the broader narrative of sustainable development and environmental stewardship. The building is to be upgraded to a B1 BRE Rating All external windows, doors and curtain walling to be removed and replaced with triple glazed units achieving a minimum 1.2 U value. All roller shutter doors are to be retained as they currently exist. Replace and upgrade the existing steel doors to Transmission Store, Stations Store, Construction Store, General Workshop, Metre Workshop/ Booster Workshop which are to achieve a minimum 1.4 U Value.
