Abstract

Reducing energy demands in buildings has become a key interest to achieve net-zero goals. Jordan, as a country, imports over 95% of its energy from neighbouring countries, initiating the need to find strategies to reduce energy consumption. This research investigates the feasibility of achieving energy savings by retrofitting heritage buildings with preservation conditions. Specifically, the study assesses the effects of building’s fabric interventions and systems interventions on heating, cooling, and lighting loads using Ladybug tools in Grasshopper3D as a modelling method. Retrofit measures encompass changes in glazing type, incorporation of shading devices for existing windows, reduction in infiltration rates, addition of thermal insulation, enhancement of sensible heat recovery efficiency, and interventions in the lighting system by lowering lighting power density and introducing a daylight control system. Additionally, the study explores the potential of integrating renewable energy sources, such as photovoltaic panels for sustainable energy production. Results indicate that fabric interventions, like adding a 30 mm aerogel layer for thermal insulation, yield over 10% energy savings. Similarly, introducing a daylight control system can reduce the demands by 11%. The study establishes a systematic framework for energy modelling applicable to buildings with similar conditions, providing valuable insights for sustainable retrofitting strategies. KEYWORDS: Energy consumption, heritage buildings, retrofit, daylight control, renewable energy.
