Abstract - Energy Positive Buildings (EPBs) represent an
In response to these challenges, the concept of Energy Positive Buildings (EPBs) has emerged as a progressive step beyond conventional and net-zero energy buildings. Unlike traditional buildings that rely entirely on external energy sources, and net-zero buildings that balance energy consumption with generation, EPBs are designed to generate more energy than they consume over their operational lifecycle. This is achieved through a combination of passive design strategies such as building orientation, insulation, natural ventilation, and day lighting and active systems including renewable energy technologies like solar photovoltaic panels and energy storage systems.
advanced approach to sustainable construction, where buildings generate more energy than they consume during their operational lifecycle. With the rapid growth of the building sector and increasing energy demand, especially in developing countries like India, the need for efficient and sustainable construction practices has become critical. This paper examines the role of project management in successfully delivering Energy Positive Buildings within the constraints of cost, time, and quality The study explores how modern project management tools such as Building Information Modelling (BIM), Integrated Project Delivery (IPD), and Lean Construction contribute to improved coordination, risk management, and resource optimization. It also identifies key challenges such as high initial costs, lack of technical expertise, and stakeholder coordination issues. Through literature review and case study analysis, the paper highlights best practices and proposes a structured framework for integrating sustainability goals with project management strategies. The findings indicate that effective project management is essential to balance sustainability objectives with project constraints, ensuring successful delivery of Energy Positive Buildings.
The adoption of EPBs represents a paradigm shift in the construction industry, moving from energy efficiency toward energy surplus and sustainability. However, achieving this level of performance is not solely dependent on design and technology. The successful delivery of EPBs requires effective project management to ensure that sustainability objectives are integrated with traditional project constraints, namely cost, time, and quality. Construction projects are inherently complex, involving multiple stakeholders, interdisciplinary coordination, and dynamic processes. Without proper management, even well-designed sustainable buildings may fail to achieve their intended performance.

1. INTRODUCTION This The global construction industry is one of the largest consumers of energy and a major contributor to greenhouse gas emissions, making it a critical sector in addressing climate change and sustainability challenges. Buildings alone account for approximately 30–40% of total global energy consumption and a significant portion of carbon dioxide emissions. In rapidly developing countries such as India, the demand for energy in the building sector is increasing at an unprecedented rate due to urbanization, population growth, and infrastructure development. This growing demand places immense pressure on natural resources and energy systems, highlighting the urgent need for innovative and sustainable building solutions.

Delivery (IPD) has further enhanced the capability of project managers to handle complex sustainable projects. These tools enable better visualization, coordination, and real-time monitoring, thereby improving project efficiency and reducing uncertainties. Despite the advantages, the implementation of Energy Positive Buildings faces several challenges, including high initial costs, lack of technical expertise, resistance to adopting new technologies, and insufficient policy support. Addressing these challenges requires a structured project management approach that incorporates sustainability at every stage of the project lifecycle from conceptual design to operation and maintenance.
