Analysis Effect Of Addition Woven Sugar Palm Husk For Diffusion Of Space

The degree of diffuseness of the space can be measured using the coherence of two or more measurement positions. The value of coherence can be determined using manual calculation, Matlab calculation and software Realtime Analyzer.

An experiment has done in a semi-anechoic chamber. From the determinations of coherence show that Matlab calculation is the most appropriate method to determine the coherence value. It can be shown from the value of coherence in the empty room and changes with addition woven sugar palm husk and woven coconut husk.

Characterizing The Speech Intelligibility Open Plan Office With Green Building Concept (Case Study Eecchi)

Energy efficiency is one of benefits in an open plan office concept. The absence of boundaries that reach the height of ceiling enable the building users to use a single lightning and air conditioning system. In general, boundaries is made from non permanent dry wall panels and architectural elements.
