<p>Building sector has been one of major contributors to global warming due to the excessive energy consumption during its lifecycle. In this context utilization of alternate energy resources such as solar, wind and biomass; as a replacement for conventional energy resources could be beneficially applied for achieving potential savings in power consumption. Adaptation of non- conventional energy resources combined with use of energy saving fixtures offer a sustainable solution for the increasing energy needs and environmental issues with conventional energy sources. In the present work feasibility studies were carried out for upgrading the existing building i.e. Annapurna bhawan in Jaypee University of Engineering &amp; Technology (JUET), Madhya Pradesh, India; into an energy efficient building. Annapurna bhawan encompasses kitchen and four dining halls, being used for cooking and serving food to the students in the university. Study examines the potential benefits of using biomass energy through continuous anaerobic digestion and solar photovoltaic modules as a replacement to conventional energy sources. Results suggest potential energy savings and economic benefits could be achieved through the installation of these systems.</p>
