A. The urban certificate is the information document by means of which the
authorities, in compliance with the related provisions of the urban plans (and
related regulations) and land development plans (noti

ed and approved

according to the law),

make known to the applicant the elements regarding the judicial, eco-
nomic, and technical status of the lands and buildings existent at the date of
the request and

and list of legal approvals and agreements necessary to authorize.

B. Technical documentation for building permit is a fragment of the technical
project and is drawn up in accordance with the frame-content, requirements of
the town

cate and the notices and agreements thereto; it is
drawn up, signed, and veri

1.3 Local Needs Analysis for mCCHP System
Implementation

The purpose of this local needs analysis for mCCHP system implementation is
identifying the location inside or outside house of mCCHP system and the topology
of its components, in accordance with the general principles on which the concept
of trigeneration is based, and considering the energy resources available in the
region. The analysis was performed from three points of view:

in terms of structures (charts), at block diagram level and of energy distribution
system integrated to building;

￿

￿ from the functional point of view, represented by the degree of complexity

(limited by certain barriers) and energy ef ciency (EFF);

￿ from the architectural limitation imposed by building permit.

The comparative analysis in terms of structure, at block diagram level, leads to a
conceptual scheme for the mCCHP system based on the use of renewable energy
(solar energy and energy from the combustion of biomass) and thermal energy
distribution by hot/cold water to ventilator-convectors.
From the functional point of view, the analysis performed of the appropriate
systems for the production of cold, the following conclusions can be drawn:

both absorption and adsorption systems can be used successfully in generating
cold within the trigeneration systems;

￿

the use of refrigerating systems with high temperature heat flows requires

cumulative absorption systems (in several steps), relatively complex and hence
of the low reliability;

￿

adsorption refrigeration system does not emit toxic gases and can be mounted
inside the building.
