While there is a viable increase in the incorporation of gardens and outdoor spaces in residential facilities for elderly which offers them great opportunity to have a healthy life style to be active and to interact with neighbors, however these spaces remain less utilized despite many identified benefits. This can be due to combination of increasing frailty in late life and barriers in accessing the outdoor environments. Therefore, a balance of well-designed easily accessible outdoor environment, and an environment that brings the great natural outdoors into the built indoor environment is much needed in elderly housing design. Biophilic design concept in elderly care design can be approached to refine and rethink the outdoor space and moreover, in the indoor space by consciously incorporating greenery, we are unconsciously reconnecting them with nature. These biophilic design spaces becomes a great source of active social interaction among the users as well. The purpose of this study is to identify on what spaces do the elderly take satisfaction in when it comes to interactive amenities spaces that is provided for them in their residential community and how those spaces can be approached by adopting biophilic design principles. The empirical material of the research consists of case study and an online questionnaire. To study the impact of biophilia design in elderly housing, specific cases which were designed by adopting biophilic design in elderly care were studied, then an online survey was conducted with 30 elderly participants from India and Republic of Korea to know their preferences towards providing them a biophilic interactive space in their housing environment.

This paper investigates numerically the combined effect of employing multiple Phase change materials (PCMs) and dispersion of high conductivity particles on the thermal performance of an energy storage unit. The key parameters that govern the performance have been identified following a simple reduction of variables. Among the different parameters, melting temperature of the PCMs, latent heat and melting temperature difference between two consecutive PCMs (DT m ) are found to have a significant influence on the performance. A case study considering a 3-PCM unit to study the effect of key parameters during melting has been presented. The results show that for the 3-PCM unit, the performance is better when the second and third PCMs placed have their latent heats larger than the first PCM. It has been recommended to have DT m1 > DT m2 for the 3-PCM unit in order achieve more melting.
