Last February 17, 2012, the 2nd IIEE-CRCSA Technical Seminar kicked off with a good response from the members and non-members with the participation of more than 100 who showed-up at the White Palace Hotel, Riyadh, Saudi Arabia. Seminar title was “Basics of Indoor Lighting using DIALux”. The seminar was conducted by Engr. Michael T. Santiago, a Lighting Application & Design Engineer from Saudi Lighting Company. The participants were awed by his DIALux 4.10 software demonstration specially when he imported a room layout from AutoCad drawing and applied the lighting calculation on it which later provided a very nice colored 3-D drawing of the room. A continuation of this seminar which is “Basics of Outdoor Lighting” will be presented on the incoming 14th Midyear Convention.
