Abstract

Recently, the feasibility study on occupancy, building design and its operation are critical issues in building certification. This study evaluates green concept of a high-rise building, Grand Darmo Suite Hotel Surabaya-an awarded on green building as case study, to the architectural feasibility. The modeling using Ecotect Analysis and CFD Fluent program combined with field observation were also conducted to evaluate the building performance. Based on building simulation and the walkthrough survey and audit, the results show that the building has architectural aspect and advantage, it remains in consistent way between the initial planning and the development. In general, the green concept is implemented in organization of space and its use where they are in accordance with the functions and appropriate to building permit. Furthermore, the condition and quality of the finishing material do not interfere the comfort of occupancy.

Abstract

Houses in warm and humid tropical regions, like Indonesia, often experience uncomfortable conditions due to high temperatures aggravated by high humidity. With its adsorptive characteristics, natural coconut fiber can be utilized as wall panels and assigned to regulate house humidity levels. Research focusing on investigating the adsorptive capability of the natural coconut fiber in controlling humidity is widely available, but that specifically examines the effect of the surface area of the material on air humidity conditions in humid tropical extant houses is still limited. A field experiment was conducted in a small Surabaya house. The study analyzes the impact of coconut fiber (CF) wall panels on humidity conditions in each house room and the optimal surface area of the wall panels. CF wall panels were found to reduce the indoor relative humidity (RH) significantly. The optimal surface area varied depending on room characteristics. The optimal surface area of the wall panels for the living room is six (6) m² with a 28% RH reduction, for the bedroom is six (6) m² with a 27% reduction, and for the kitchen is five (5) m² with a 27% reduction.
