Short presentation
The project
proposes a research study focused on emphasizing the exergy of the natural
and built environment, with a view to build dwelling and public buildings
with a reduced consumption of conventional energy. The project is focused on
the implementation in the buildings structure of intelligent envelopes, of
systems of monitoring and managing systems based on the duplex prediction -
correction as well as on the systems which ensure thermal and physiological
comfort based on the reasonable use of the heat transfer vectors through
radiation and convection in the occupied spaces. Three systems equipped with
energy efficient envelopes will be studied, as follows:
1. System S1
represented by the ventilated solar space connected to a dwelling type
building. The system is part of the structure of an experimental building
located within INCERC Bucharest.
2. System S2
is an innovative system represented by the variable heat envelope variable
thermal resistance of the wall type with an effect parietal-dynamic on then
exhaustion of the polluted air from the occupied spaces and the envelope of
the endothermic type for the efficient use of the solar energy and of the
exergy of the outdoor air exergy.
The experiments will be based on the support of a natural scale physical
model which will operate within INCERC Bucharest together with a witness
model. The experimental platform will be used as a permanent research
laboratory for the exergetic envelopes, useful for the technological
applications as well as for the experts’ training in the sector. The models
will equally be available for visit and for potential beneficiaries.
3. The S3
entirely glazed envelope in the form of the S3.1 drape wall and which in
terms of the experiment will be represented by an office building in
Bucharest. The
complementary system of the Double Skin S3.2 type will be analyzed on the
support of a complex mathematical, numerical and analytical model. The
analysis of this type of facades, increasingly frequently used for office
buildings and in the case of the systems meant to ensure the microclimate in
the adjoining occupied spaces, is a highly topical issue as serious problems
are obvious in connection with the assurance of the indoor comfort and
especially because of the energy consumption increase.
Scope and obiectives
The ANVINTEX Project proposal accomplishes the following targets
derived from Programme 4 regarding the development of the knowledge within
the Environment research division through the research themes focused on:
- Intelligent envelope
systems,
- Systems of conceiving
and design of new buildings with a very reduced heat consumption,
- Materials which
improve the inside microclimate with a reduced heat consumption through the
use of nano-sensors and of the information/computer technology.
The targets of the ANVINTEX research project are subordinated to
the European and national concern related to the reducing of the energy
consumption in buildings and implicitly to the reducing of noxious substances
with greenhouse effect, according to the European Directives 91/2002/EEC on
the Buildings Energy Efficiency at the Final Consumer. Both of the documents
underline the important impact of buildings on the high energy consumption, of
which the buildings represent about 40%.
The scope of the proposed project consist in theoretical and
experimental analysis on models at the natural scale of three types of
envelopes efficiently using the exergy of the natural and built environment
and contributes to the significant reducing of the energy consumption of the
dwelling and public buildings, at the same time with the increase of the
thermal and physiological comfort.
A derivative
target is represented by the promotion on the internal and external market of
the products and equipments meant for constructions, of the innovative
elements, representing the object of the research, namely:
- parieto-dynamic effect wall, on the exhaustion of the polluted
air and the controllable thermal resistance,
- endothermic façade,
- ceiling with controlled radiant-convective effect,
- ventilated solar space,
- monitoring and predictive - corrective and control computer system.
At the same time, the project will specifically focus on the
behavior of the public buildings of the office type with entirely glazed
facades which are increasingly frequent in the urban landscape, following the
issues related to the specific excessive energy consumption. The measurements
performed on a building in Bucharest
and the theoretical research based on the numerical modeling of the processes
specific to the Double Skin facades will introduce new elements in a sector
very little approached internationally and nationally. The target is to
improve the energy-related behavior of this type of buildings.
Activities
The activities are included in 5 Phases as follows:
Phase 1 - It includes the presentation and the quality analysis
of the "exergetic envelopes" solutions as well as of the estimated comfort
and energy consumption parameters. During this phase, the dynamic
mathematical model of S1 is drawn up and the measurement chain specific to
the experiment concerning S1 is ensured. The project website is created;
Phase 2 - It mainly includes the mathematical model of the
physical processes specific to the subsystems included in the innovative
system S2 as well as of systems S3.1 and S3.2 (numerical and analytical
modeling). Based on the mathematical models, the components of system S2 are
dimensioned, the project design of the INCERC Experimental Platform is issued
and the measurement chains of the above-mentioned systems are conceived.
Simultaneously, the S.I. project of command and predictive-reactive control
of system S2 is carried out. The Computing
Center is ensured and the data
measured at the level of the CCP (INCERC
Platform Computing
Center) is taken over;
Phase 3 - It includes the carrying out of the Experimental
Platform within INCERC and its equipping with the intelligent adjustment
computer system. The measurement chains of systems S2 and S3.1 are put into
operation and measurements are performed in the cold season. The experiments
schedule concerning system S1 is completed. The virtual models CVR and CVP
are drawn up. A page on the dynamic display of the processed data is added to
the website;
Phase 4 - It represents the phase of Validation of the
mathematical models of systems S1 and S3.1 based on the measurements
performed in the cold and hot seasons. The remote control system specific to
the INCERC
Platform Computing
Center is implemented.
Measurements are performed in the hot season on the system S2 support. The
"Exergetic Architecture" website is created;
Phase 5 - It is the phase devoted to the Validation of the
mathematical model of system S2. The PECM (Building energy and environment
performance) for buildings CVR and CVP is assessed. The corresponding patent
is submitted. The analysis of COP is performed following the including of PC
in a system equipped with an exergetic envelope. The report on the operation
of the S.I. computer system is submitted. Activities of dissemination to PTCE
and ENBRI, Workshop and issuing of the Good Practice Guide concerning the
systems studied in view of implementation in the design and construction
activity.
During the project development, activities such as the
participation in conferences and workshops un Romania and abroad will also be
carried out.

PECM of the buildings equipped with exergetic envelopes (system S1, S2, S3.1
and S3.2) which will be the object of notification to be sent to the
international and European standardizing institutions CEN and ISO,
(2) Performance of the predictor -
corrector intelligent management systems by the information system,

and UAUIM in view of attesting energy auditors for building.
