About Simon

Building automation expert and industry thought leader

Building Management Systems professional and author of BMS Fundamentals. Interested in computer programming since ~1982, music producer, web coder (made the CMS behind this very site), dabbler in most techy things, and occasional gamer. My wife would describe me as untidy, disorganised and a geek.
