METHODOLOGY FOR CALCULATION OF ADDED VALUE
GENERATED BY ENERGY EFFICIENCY
by
DANIELA POPESCU, SVEN BIENERT and CHRISTIAN
SCHÜTZENHOFER
Abstract. The paper presents a method to be used for estimation of
value of buildings, by including energy efficiency aspects. The method is
based on calculation of the added value generated by costs of potential
energy savings. A case study, based on real-estate market data from the
city of Iasi is presented. The results confirm that by taking into
consideration costs of potential energy savings in valuation procedure,
the estimated value of properties is calculated more correctly.
Key words: Energy Performance Certificate, valuation, sales
comparison approach, energy savings.
JET OF MIST WARM WATER BEHAVIOUR IN INTERACTION
WITH HYDROCARBON FLAME

PANAITESCU
Abstract. The paper presents the theoretical and experimental
aspects concerning the jet using the mist of warm water for the
hydrocarbon flame extinguish. In the first part of the work are shown the
specific theoretical aspects concerning the liquid phase evaporation in a
surrounding as a function of the humidity and temperature. This fact
generates a change of the atmosphere temperature and composition.
Based on these particularities of the droplet evaporation processes, an
experimental bench was developed. The influence of the liquid
temperature on the fineness spray atomisation in the surrounding was
exposed. The elements resulting from the experimental tests as the jet
development and evaporation were exposed. The experiment suggests
that the liquid phase in contact with the flame evaporates
instantaneously. Consequently, due to the huge volume of vapor, the
oxygen concentration in the mixture might falls under the ignition limit.
