My doctoral research delves into the intersection of health and energy (health—Energy Nexus) within indoor spaces, where we predominantly spend the majority of our lives. My aim is to optimize building energy consumption while enhancing the quality of the indoor environment, with a focus on indoor air quality (IAQ) and thermal comfort as pivotal components of indoor environmental quality (IEQ). Areas of expertise: —- Building Energy Modelling —- Sustainability Analysis —- Life Cycle Assessment (LCA) for IEQ enhancement solutions —- Carbon footprint evaluation of decentralized energy systems —- HVAC operational strategies and ventilation management —- Sustainable solid waste management Ehsan Alam
