In cold weather, focus on heating messages; in hot weather, highlight

cooling. For the rest of the time, considering messages which deal

Proposal:

Thinking the technical project doesn’t finish in ELIH-MED:

- The project is divided in different phases

- It is necessary to develop a road map for each pilot

project ( only “design” how to get nearly zero energy

building)

-They could to continue the works of improvement when

they get more money (recapitalization in the future)

-At the same time it is important to develop maintenance

plan for the users ( guide about the actions to conserve the

thermal performance of roofs, façades,… and the solar water

system, etc. and, also, how use them)

Diagnosis

:

output

Cost

economic

optimum

The area of the curve to the

right of the economic

optimum represents

solutions that underperform in

both aspects (environmental

and financial).

To prepare for higher energy

or environmental targets (e.g.

related to 2020),

certain Member States might

choose even stricter

requirements than the

economic optimum (left area

of the curve).
