BEEP Guide for the energy renovation of heritage buildings


The ENI CBC Med BEEP project comes to an end after a 40-months journey. One of its main outcomes has been the development of a guideline on the energy and environmental improvement of public historic buildings using the “Heritage Building Information modelling (HBIM)” methodology and simulation-based approach.


The guideline presents a workflow, from building analysis to the design, simulation and evaluation of interventions, that can be applied by building owners and managers and can be useful for all the professionals involved in the process. It also describes the potential and the application of the use of Energy Performance Contracts (EPC) as financing mechanism.

This guideline aims to enhance the capacity of public local administrations and professionals of the Architecture, Engineering and Construction (AEC) sector to design and carry out sensitive retrofitting interventions on historic public buildings, through a multidisciplinary and integrated digital approach (using Building Information Modelling and performance-based design to develop an Energy Efficient Heritage Building Information Model - EE-HBIM).

The guideline is based on the testing of this emerging technology on nine heritage public buildings located in Italy, Spain, Cyprus, Jordan, Palestine, Lebanon, and Egypt to demonstrate its scalability to the entire building stock of the Med area.

About the BEEP project:

BEEP project aims at strengthening the use of Building Information Modelling (BIM) to enhance energy efficiency in buildings. The testing of this emerging technology on built heritage will be performed to demonstrate its scalability to the entire building stock. The project will provide public administrations with a powerful method for the energy rehabilitation of public buildings to be supported with private funds through the Energy Performance Contracting (*). The project main outcome will be an innovative methodology based on the integration of emerging technologies tested on 9 heritage public buildings located in Italy, Spain, Cyprus, Jordan, Palestine, Lebanon, and Egypt.

(*) Energy performance contracting (EPC) is a mechanism for organising the energy efficiency financing. The EPC involves an Energy Service Company (ESCO) which provides various services, such as finances and guaranteed energy savings. The remuneration of the ESCO depends on the achievement of the guaranteed savings. The ESCO stays involved in the measurement and verification process for the energy savings in the repayment period. ESCO and energy performance contracting are mostly found in the public sector and to a lesser extent in the industrial and commercial building sectors (Hilke and Ryan, 2012).
