Assessment of the renewable energy production in a historical building for a touristic intended use: a technical-economic feasibility study

Abstract

This column deals about a study based on technical and economical feasibility of a combination of technologies and systems for energy production concerning electric, heating and cooling to install on a building in the historic centre of a Sicilian city (Italy). After a functional review and an energetic evaluation, the building will have a hotel destination. A first evaluation, made on a model set with the geometrical, thermo-physical and climatic data both of the building and the place, allowed to make a dynamic simulation to define the energetic monthly needs. The evaluation has been done considering different solutions and technologies. With the collected data we supposed a first sizing of the HVAC systems used for the next economical evaluation. We considered the expenses for realization and the energy saved using methods called “Actualized net value” and “Payback Time”. The final analysis shows benefits and disadvantages on each simulations with every kind of technologies used helping us to decide what to use.
