Abstract
The use of thermal mass in buildings is an effective way to improve the
building’s interior comfort in places with high diurnal temperature variation.
Combined with other passive strategies, thermal mass can play an important role
in the energy efficiency of the building, minimizing the necessity of the
traditional conditioning systems. However contemporary construction tends to
industrializing light weight systems with low thermal mass. An innovative way
to add the thermal mass` benefits to the buildings is the use of the latent heat
thermal storage capacity of the Phase Change Materials (PCM). In the Solar
Decathlon, solar houses competition organized by the United States Department
of Energy. The houses are tested and monitored in Washington DC, where the
use of short term thermal storage systems is adequate to maintain the interior
comfort and reduce energy consumption, therefore many teams had incorporated
PCM in theirs industrialized lightweight houses. In this paper the solutions on
the application of PCM used in this competition are discussed.
Keywords: PCM, latent heat, energy storage, solar decathlon, TES.
1 Introduction
Solar Decathlon (SD) is a biennial international competition and public event
organized by the U.S. Department of Energy’s, in which 20 university teams
from around the world compete to design, build, and operate solar-powered
houses that are cost-effective, energy-efficient, and attractive [1, 2]. The SD
Keywords
PCM, latent heat, energy storage, solar decathlon, TES.
