ThisTheglobal constructionindustryisoneofthelargest consumersofenergyandamajorcontributortogreenhouse gas emissions, making it a critical sector in addressing climatechangeandsustainabilitychallenges.Buildingsalone account for approximately 30–40% of total global energy consumption and a significant portion of carbon dioxide emissions.InrapidlydevelopingcountriessuchasIndia,the demandforenergyinthebuildingsectorisincreasingatan unprecedentedrateduetourbanization,populationgrowth, and infrastructure development. This growing demand placesimmensepressureonnaturalresourcesandenergy systems, highlighting the urgent need for innovative and sustainablebuildingsolutions.
In response to these challenges, the concept of Energy PositiveBuildings(EPBs)hasemergedasaprogressivestep beyondconventionalandnet-zeroenergybuildings.Unlike traditional buildings that rely entirely on external energy sources, and net-zero buildings that balance energy consumptionwithgeneration,EPBsaredesignedtogenerate more energy than they consume over their operational lifecycle.Thisisachievedthroughacombinationofpassive design strategies such as building orientation, insulation, natural ventilation, and day lighting and active systems including renewable energy technologies like solar photovoltaicpanelsandenergystoragesystems.
The adoption of EPBs represents a paradigm shift in the constructionindustry,movingfromenergyefficiencytoward energysurplusandsustainability.However,achievingthis levelofperformanceisnotsolelydependentondesignand technology. The successful delivery of EPBs requires effectiveprojectmanagementtoensurethatsustainability objectivesareintegratedwithtraditionalprojectconstraints, 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.
Projectmanagementplaysapivotalroleinaligningdesign intent with execution by facilitating planning, scheduling, costcontrol,qualityassurance,andriskmanagement.The integration of modern tools such as Building Information Modelling(BIM),digitaltwins,andintegratedproject Delivery(IPD)hasfurtherenhancedthecapabilityofproject managers to handle complex sustainable projects. These toolsenablebettervisualization,coordination,andreal-time monitoring, thereby improving project efficiency and reducinguncertainties.
Despite the advantages, the implementation of Energy Positive Buildings faces several challenges, including high initial costs, lack of technical expertise, resistance to adoptingnewtechnologies,andinsufficientpolicysupport. Addressing these challenges requires a structured project management approach that incorporates sustainability at everystageoftheprojectlifecyclefromconceptualdesignto operationandmaintenance.
