Comparativa entre sistemas constructivos de huecos para ascensores en función del análisis de ciclo de vida

Abstract

• This paper compares environmental impact of

traditional construction systems of hoistways

made for elevators in residential building

sites, using techniques based on Life Cycle

Analysis (LCA), calculation of carbon footprint,

quantifying total energy consumption and

emissions in the material used as well as building

and recycling of all materials in use. Furthermore,

other environmental variables directly related

with environment sustainability will be studied.

We have simulated the analysis with a time

frame of 50 years, 100 km track average for the

transporting of materials and 15 km residues

distance average from rubbish dump.

The ceramic brick wall has proved to have the

best behavior from building and maintenance

cost, risk in health and safety and intensive use

of workers point of view, variables all related

with economical building aspects. On the other

hand, from sustainability point of view it is

proved that the ½ ceramic brick walls with rock

wool insulation and one final layer with ceramic

brick had the best environmental sustainability

behavior.

It proved that from an environmental

sustainability point of view, traditional materials

and masonry construction systems are less

polluting than concrete construction systems,

showing advantages in building design when the

sustainability concepts are applied in materials

selection and construction techniques.
