30-72 DEPRESURIZAREA ATRIUMULUI ÎN CAZ DE INCENDIU

DEPRESSURIZATION OF THE ATRIUM
IN CASE OF FIRE
A greater architectural freedom becomes possible when the atrium
façade should not be sealed, even if its upper part is filled with smoke if the
atrium or the adjacent spaces have a fire. The methods described in this article
refer to all categories of construction, in which the classical methods,
mentioned in specialized legislation, cannot be applied.
Keywords: fire, smoke, atrium, depressurization, vent
Cuvinte cheie: incendiu, fum, atrium, depresurizare, ventilare

CONCEPTUAL ASPECTS ABOUT INCREASING ENERGETICAL AND ECOLOGICAL PERFORMANCES OF BUILDINGS IN THE REPUBLIC OF MOLDOVA
In this scientific article we are talking about specific concepts that can be used for energetically and ecological performance incensement of buildings in the Republic of Moldova and also the results that we abstain doing the energetically audits for a big varieties of buildings from our country.

28-12 MODELUL MATEMATIC SIMPLIFICAT PENTRU VERIFICAREA DIMENSIONĂRII DESCHIDERILOR PENTRU EVACUARE A FUMULUI ÎN CAZ DE INCENDIU

THE SIMPLIFIED MATHEMATICAL MODEL TO VERIFY DIMENSIONING OF THE OPENINGS FOR SMOKE EVACUATION IN CASE OF FIRE
This article derives engineering equations used to calculate pressure differences across vents, as well as equations for calculating the mass flow of gases out through the vent, for several common enclosure fire scenarios. This gives information on the mass and energy balance and therefore allows calculation of such environmental consequences as hot gas temperature and smoke layer height.

TECHNICAL ISSUES RELATING TO FIRE PROTECTION
FOR THE DESIGN DOUBLE SKIN FACADES
Usually for a building with a multi-storeys double-skin facade, smoke
of a fire room escaping through the inner facade into the intermediate space
between the two skins may accumulate and spread horizontally and/or
vertically to other rooms that have openings connected to the intermediate
space for the purpose of natural ventilation.

26-8 CONSIDERAŢII PRIVIND OPORTUNITATEA PROGNOZEI CONSUMULUI DE GAZE NATURALE ÎN REPUBLICA MOLDOVA

CONSIDERATION ABOUT THE OPPORTUNITY OF NATURAL
GASES PROGNOSES IN THE REPUBLIC OF MOLDOVA
Of all forms of primary energy currently participating almost to
meeting energy needs in Moldova gas lies the largest share – about 60 % full
resources imported from the foreign market carriers energy. Therefore the
problem of determining, monitoring and control of natural gas consumption, and
estimate its possibilities of coverage opportunities is an actual goal, which
raged experts in the field.

26-7 STADIUL ACTUAL ÎN DOMENIUL EFICIENŢEI ENERGETICE DIN REPUBLICA MOLDOVA

THE CURRENT STATE IN THE FIELD OF ENERGY
EFFICIENCY IN THE REPUBLIC OF MOLDOVA
The increase in the cost of energy resources, the advanced
depreciation of the buildings, the degradation of the environmental quality and
the Moldova’s total dependence on the external energy markets, are essentially
the key arguments which require the promotion of some consistent national
policies in the field of energy efficiency in all spheres of human activity. In this
context one area over which it can act with certainty is the field of buildings. The
analysis of housing in Moldova built at different stages under different
architectural and structural solutions, the evolution of energy usage and energy
resources for various sectors of the national economy, as well as the objectives
put forward by the national strategies and programs for energy efficiency are
presented in the paper.

This paper proposes the application of the SVEFGH programmed,
conceived on the base of standardized calculating procedures (CEN/TR 12101-
5:2007), for the depressurization of an atrium with open floors towards this from an
arson building and comparing the results with those obtained with the FDS (Fire
