Abstract

The sustainability and efficiency of buildings represents a crucial issue since the building sector is currently responsible for more than 40% of energy consumption and emissions. This concern is extended to historical buildings, as they are typically low-performance constructions usually equipped with ineffective systems. For these reasons, the upgrade of historical constructions from an energy and environmental perspective is urgent, especially in those countries where such buildings represent more than half of the building stock. This work concerns the refurbishment of a historical Italian building by integrating passive and active solutions to optimize the indoor thermal comfort and the energy performance. To this aim, the innovative GBC Historic Building® rating system, a new tool evaluating the sustainability level of conservation-related activities on pre-industrial buildings, is applied. A combined trigeneration heat and power plant with an absorption chiller to produce cooling and powered by vegetable oil is installed in the building. A dynamic simulation of the building is also carried out to predict the post-retrofit energy performance upgrading. The final aim is to propose an integrated approach for the preservation and energy upgrading of existing constructions by improving their energy performance and environmental quality while protecting their heritage value.
