This research aims to study Design guidelines for home decoration woven from pandanus odoratissimus linn the woven pandanus Phanans home parish of the island of Koh Lanta Krabi. Sample in Research is foreign tourists 50 peoples and Local 50 peoples. Want to buy product Home decoration Krabi. The research instrument was a questionnaire want side different of the target audience have confidence equal to .890 statistical analysis was performed by percentage. Average mode and questionnaire to evaluate satisfaction in the field of use and in marketing for home decoration woven from pandanus in the process of evaluating alternatives and in the assessment process compare with the original souvenirs by questionnaire 2 edition have confidence equal to .893 and .830 respectively. Statistical analysis was performed by means of percentage mean and test the hypothesis with the t-test statistic type Dependent Sample. The research concludes that. 1. Workings portfolio design home decoration method 1 small put of box can adjust the size between channels. Method 2 box put of large removable foldable and Method 3 small table of lamp removable foldable. 2. Target groups choose the design of home decor in the 3 approach. 3. The target audience is satisfied with the new home decor more than the original in all sides. Statistically significant at the .05 level dealers are more satisfied than the original model in almost every aspect. Except for eco-friendly images and the new home decor is more effective than the old one.

This study focuses on appropriate opening design of natural ventilation for green chemistry laboratories in Thailand. Even though natural ventilation is an alternative way to save energy from using air conditionings nowadays there is no design guideline to promote natural ventilation for chemistry laboratories in the country. Computational fluid dynamics (CFD) was used to simulate building models with various orientations and opening types. Then a set of simulations was run to test the effect of lay-out designs and opening locations in conjunction with the type of building models such as single-loaded corridor double-loaded corridor and atrium-loaded corridor by comparing ventilation performance with 8 wind directions at the speed of 2 meters per second. Results show that the single-loaded corridor lay-out design and opening arrangement which angled at 180 degree of wind direction and average wind speed of more than 0.5 meter per second was the most suitable comfort for improved natural ventilation in chemistry laboratories. Natural ventilation helps in reducing energy consumption improving quality of indoor environment and responding to the need of users based on standards and principles of green chemistry laboratory design.
