Efficiency Potential in Buildings, in New
Member States and Candidate Countries”).
The CREFEN project is connected with
energy efficient use according to EU
directives from one side and with the
implementation of database applications
using web-based technologies to assist and
influence the people decision in selecting
the households appliances from the other
side, that leading to sustainable
environment management.
The proposed project is part of the field 5
“Energy - 5.8 Energy efficiency and
saving” of Romanian CEEX program,
contributing to the efficient use of the
energy for reaching the EU standards and to
the development of software applications
aimed to assist the citizen decisions and
determine it for the already mentioned
objective with environmental impact.
3. Methodology and software
Modeling and simulation in energy field
and web-based applications with databases
is a complex and dynamic domain, leading
to an important research and development
potential with important practical
implications. The project aims to develop
an advanced modeling and simulation
software system-tool of electric energy
consumption in residential sector and of
economical effects, to implement an
application with databases, an interactive
educational application and electronic book
in the field of energy efficiency use in order
to influence the consumers’ options in
selecting energy efficient appliances for
environmental protection by reducing the
CO2 emissions. This approach is quite new
in Romania. The scientific knowledge in

the field (algorithms for calculation of
energy consumption, IT technologies) is
connected with technical aspects
concerning its implementation as a webbased
application containing in its database
the most of the technical features of
domestic and lighting appliances available
in Romania.
The Application is complex both by its
multidisciplinary and proposed IT solution.
The accessibility will be solved by using
web-based solutions. The user needs only a
browser in order to be connected to the
system without other specific applications.
It is also possible to use public terminals
with touch screens. The performances of
this application take into consideration the
user friendly interface, the reliability, data
security, high speed provided by Microsoft
SQL Server 2000 DBMS. The data
protection will be assured both by specific
Internet control access mechanisms (proxy
server) and by internal mechanisms of the
relational DBMS Microsoft SQL Server
2000. The application will be available also
on stand-alone computers for locations
without Internet connection. The proposed
software system will include a complex of
interconnected databases, a software system
for the management of these data and a
system for accessing them via Internet. The
most recent platforms and software
products for developing the Internet-based
applications with databases (ASP.net, SQL
Server, Java, OLAP) will be used.
The application architecture will be a
modular one, with the possibility of its
extension with new functionalities, without
perturbing the other components or requiring
the reorganization of the system data.
