Collection and sharing of past experiences and best practices regarding the implementation of EPC for buildings in MED area was based on a common scheme for data collection.
National, regional, sub-regional and local authorities at MED and EU level that have tested the EPC scheme in buildings refurbishment were contacted to highlight the best practices.
All info collected is the subject of a critical revision by the partners, in order to select those methodologies, technical approaches tactics and deployment methods that better fit with the MED conditions. They served as a baseline for the elaboration of methodologies being tested and applied inside pilot actions of STEPPING project.
The objective of evaluating EPC Best Practices in Mediterranean area (MED) was to find some common factors to help us defining and design a particular Energy Performance Contract (EPC) model adapted to MED Area.
To this end, a series of consensual parameters were sent to all partners to collect and analyze the data. Even with the absence of data that define the type of EPC contracts in non-MED territories, the correlations or common factors found in the analyzed BPs gave us an idea of such contracts characterization in the MED Area. More information about EPC framework in all European countries can be found in other H2020 projects as Transparense and EPC+.
Information about Best Practices gathered from all STEPPING project partners is divided into ten sections: Basic information, Buildings’ data, Technical parameters, Contracted measures, Contract related figures, Contracting models applied, Funding approaches, Types of buildings included in the contracts, Tender approaches and Awarding procedure.
Results of the initial best practices analysis, the EPC projects profiling in public buildings located in MED area are very diverse:
a) The most often owners of buildings are municipalities, being educational and sports centers the most commonly found buildings;
b) The most used model of contracting (53,85%) is Multi-Type buildings, compared to 46,15 % of One Type buildings;
c) As expected, and in accordance with MED region, climate zone of actions receives a solar irradiation of around 1500 kWh/m2/year;
d) The average age of buildings is around 50 years, ranging from 3 to 156 years;
e) Standard type of EPC is the most frequently model of contracting applied, guaranteeing the achieving of energy savings for the contract duration with a range between 7-69 % and an average of 36,42 % of achieved savings;
f) The initial Investment costs which range is between 40000 and 19942886 € are mainly provided by the ESCOs. The average of such investments is 1544582 € and the total avoided CO2 emissions are more than 11400 Tm per year;
g) Regarding funding approaches, most of the undertaken actions (80%) have been financed by ESCOs having also received other grant funding 46 % of them and third part financing the 34%. A mixed scheme has been applied by 15% of the actions;
h) 38% of procedures followed the grouping methodology while 34% were Individuals, most of which (70%) were awarded by open tender. No data about tender typology of 26% BPs;
i) We find HVAC renovation, windows/glazing, building management system, Energy monitoring system, Initial energy audit, Training of users and M &V Plan as the most frequently implemented technical measures.
