All those variables mean that each building design is different, particular, and it cannot
be defined only through statistic and scientific research.
In order to implement very good solutions, high energy performance constructions and
systems are not enough as stand-alone elements, but they have to work well together,
as a unique organism and in that specific environment. This is why the designer has to
strongly consider also the specific micro-climatic condition and users habits through a
dynamic simulation model.
The test case of CasaZeroEnergy, whose thermodynamic performances were analyzed,
hour by hour, using the software package “Energy Plus” and some prototypes
implemented by EnginSoft, demonstrated that BENIMPACT Suite prototype can be used
to assess the building energy needs, for heating and cooling plant sizing, and to verify
the thermal behavior of different rooms. It also showed that it is really important to
individuate parts of the house which might behave in an odd way, and separate them in
the model.
The energy model is the first step of a more complex process that analyzes the whole
life cycle of a building. It has been integrated in BENIMPACT Suite prototype through
specific prototypes developed by EnginSoft which calculate also environmental impact
and cost of each configuration and search for the “optimal” trade-off between
environmental and economic sustainability. In fact, in order to spread the awareness of
sustainable design,
“environmental friendly” constructions
must be characterized by
“smart”
investment, and this convenience has to be proved in a scientific way, as done
for in this work the thermodynamic performances.
