Enhancing Indoor Health and Comfort in Adaptively Reused Heritage Building

Abstract

A heritage building that being adaptively reused has some concerns regarding indoor health and comfort. They are prone to cause discomfort to the occupants. The assessment based on GBCI rating tools of Indoor Health and Comfort gives the existing building (Perpustakaan Bank Indonesia) 10 credits. 1 credit for outdoor air introduction, 6 credits for chemical pollutant, 1 credit for outside view, and 1 credit for thermal comfort. This research aims to propose proper strategies, to make the building has better condition of indoor health and comfort, which represent by higher credits from GBCI rating tools. Strategies are observed, simulated, and manually calculated to enhance indoor health and comfort, as well as giving the building more credits. No-smoking campaign should be applied as prequisite criteria of indoor health and comfort. CO2 sensors are placed in computer room and kids reading area, which gives the building additional 1 credit. Maintenance and treatment for ducting system are proposed to give the building 1 more credit. Other 2 credits come from the planning of artificial lighting and individual switching system. 78% transmittance glass is proposed to enhance illuminance level, which leads the building to get another 1 credit. Standing AC unit gives higher control to the occupants in every different rooms, and this strategy gives the building another 1 credit. Treatment for noise level using green wall fence gives the building 1 credit. Interior plants (2 credits) and pest management (1 credit) are the last two strategies proposed to enhance indoor health and comfort. Those strategies give the building another 10 credits, which lead them to achieve 19 credits from 28 total credits available in the rating tools.
