  • The purpose of this study is to establish a standard for unit cooling load in central control type apartment applied district cooling. The model of unit household was selected. And the standard of coefficient of overall heat transmission, location of unit household, indoor air temperature, solar radiation & thermal conduction at window and interior load was selected, and region, expansion or non-expansion of balcony, pyeong type, azimuth, rate of window area was applied as parameter. And then cooling load simulation was performed. Based on the result of simulation, the synthetic district cooling load was presented for selecting heat source of apartment applied district cooling, and unit cooling load was analyzed according to design parameter.

  • As expansion of balconies at apartments has been legalized, the major function of the balconies as a thermal buffer zone is disappearing. This weakens the ability of window to insulate heat and multiplies surface condensation. Thus more and more residents require solutions to increasing surface condensation and aggravation in thermal comfort. This study intends to provide basic data by evaluating performance of triple layered Low-E windows, triple layered clear windows, double layered Low-E windows and double layered clear window used for expanded balconies and marketed within the country in terms of surface condensation and thermal environment through simulation. Results revealed that no surface condensation occurred at double layered Low-E windows and triple layered Low-E windows. Surface condensation took place at double layered clear windows and triple layered clear windows at a relative humidity of 60%. Thermal environment analysis suggested that double layered clear windows showed the most time falling into the range of comfort at $23^{\circ}C$. The figure were $22^{\circ}C$ for triple layered clear windows, $22^{\circ}C$ for double layered Low-E windows and $21^{\circ}C$ for triple layered Low-E windows.

  • The concept of recent cruise ship design is changing rapidly according to the expansion of cruise fleet sizes, emphasis on passenger safety and tightened requirements for ecotourism. In this view point, this study focuses on investigative analysis for the recent trends in cruise ship design and construction. Based on the shipyard production logs and the cruise industry's annual news, the data for principal dimensions of newly built cruise ships, their hull forms and propulsion devices and the characteristics of cabin and public spaces are collected and analysed. As expected, it is found that the size of cruise ships is growing and the design concept is becoming more leisure-oriented for all ages rather than lust sightseeing. For producing a greater ton/pax ratio, the adoption of podded electric propulsion system, outside cabins and balcony spaces is a common trend in recent cruise ship design.

  • Currently, brand apartment is positioning itself as one of the representative Korean housing. This allows to look into the planning side and cultural side of the Korean housing. The purpose of this study is to review the previous trend in apartment housing according to period, and to verify the trend of current Korean apartment housing by visiting the model houses in PanGyo, the new city. This study has chosen case study method of 11 cases which had been sorted out in different floor plan type and size. The findings of the study is as followed. In the aspect of spatial arrangement, it had been similar to the previous apartment plan but had a new attempt to break out from the old apartment structure by bring in round shaped living room. Also, due to the legalization of balcony expansion, various tries had been made to increase the level of function and to allow variety of usage. In the environmental aspect, the concept of wellbeing and health had been a great importance in apartment planning. In the digital aspect, various digital systems had been introduce for convenience and safety via home network system. Furthermore, based on the various lifestyle, the storytelling design concept applied in the interior design, which will have to effect the future model house design planning. Nonetheless, the current emphasis on universal design is expected to be treated one of the important concept in Korean apartment planning. This study has a significant meaning on readdressing current trend in Korean housing and to provide informations for future directions on Korean apartment planning.
