Penggunaan Panduan Mudah Pencahayaan Siang Dalam Reka Bentuk Bangunan Perpustakaan Berlainan Era

Abstract

This study investigates the use of daylighting rules of thumb in four libraries across different eras and aims to outline different guides, methods and strategies used by architects in applying daylighting design in this building typology. Two historical libraries prior to the 20th century were selected to identify the use of daylighting strategies during the times when electrical lighting was not yet available in buildings. In the other hand, two post 20th centruy libraries were also selected for a similar daylighting rules of thumb appraisal. The study reveals that three daylighting rules of thumb were commonly used in all of the library buildings appraised which include the limiting floor depth rule, window area to wall area ratio and window area to floor area ratio. It was found that the most consistent daylighting rule of thumb is the limiting floor depth whereby the depth of typical floor plan is within the range of approximately 6 meters for unilateral and 12 meters for bilateral daylighting. Each sampled library building was found to utilise a combination of daylighting rules of thumb in it’s design. This demonstrates that simple daylighting guides have been used to design library buildings in different climates, sites and eras. It also indicates that daylighting rules of thumb or simple guides have been timelessly used by architects to design well daylit library buildings.
