“…These cases set the benchmark for the remainder of the investigation. Since the passive PCM addition reduced the heating bill more than the cooling bill; and night ventilation has long been a well-documented technique for reducing cooling bills (Shaviv et al, 2001, Kolokotroni and Aronis, 1999, Geros et al, 2005, especially when coupled with thermal mass, the first hypothesis to investigate was thus: 'Ventilated PCM will reduce heating and cooling fuel consumption further'.…”

“…In the tropical climate, these two factors are both very significant, which cause buildings to employ large energy to cool the building. Cooling energy needs can be reduced using low-energy technologies [2]- [5]. The low energy ____________________________________________________________________________ 2017 / 20 53 technology suitable for each building type may differ.…”

“…Apartments were selected due to a condition of unoccupied during daytime and utilization of air-conditioners during night time. Night occupancy brings a consequence that a night cooling by means of natural ventilation [2]- [5], is not practical here. The study was limited to single bedroom or studio type unit in apartments occupied by students predominantly.…”

-Three types of apartment claddings in Surabaya, Indonesia were studied to analyze their effect into bedroom temperature. They were glass windows in a niche, glass door in a balcony, and glass windows on a plain wall with glass door in a balcony. On-site temperature measurement was recorded and complemented with questionnaire surveys of occupants' perception regarding room temperature. The study showed that an apartment cladding with the largest proportion of opaque material combined with a balcony offered an indoor temperature of up to 9 °C lower than the outdoor compared to the other cladding types. Nevertheless, 72 % of occupants participated in this study, who use air conditioners during night time, including one with the cladding with the largest temperature difference claimed that the indoor temperature before air-conditioners was still too warm, which triggered air-conditioners initial time more than 10 minutes to achieve the desired indoor temperature. It indicated that the opaque material time lag played a significant role in heating the room during night time when the air-conditioner is about to be operated.

“…As an example, several studies have shown that thermal mass together with night ventilation may reduce the indoor maximum temperature, by 2º-6ºC [8,9]. The passive strategies permit to take advance of the environmental conditions and resources, and the actives elements could accelerate heat exchange across the surface of the PCM or help to complete their charge-discharge cycles.…”

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.
