Immune buildings: Development of eWAR systems

化学和生物制剂被视为制造恐怖的首选手段，因为它们易于生产或获取，成本低。2001年对美国的犯罪恐怖袭击，对世界贸易中心的炭疽邮件，强调了建筑物中个人的脆弱性。建筑目标不仅可以包括政府或军事结构，还可以包括高知名度的商业，医疗机构以及人口密度高的结构，如购物中心。除了恐怖主义事件外，无意的化学品泄漏或某些传染性物质也会影响建筑物内的个人。建筑物内化学或生物制剂传播的主要途径是HVAC系统。不同威胁情景的共同点是，在进气口直接滴注这些制剂，在环境（或大气）中扩散，然后通过同一进气口进入

Chemical and biological agents have been viewed as a preferred means to generate terror because of their ease and low cost of production or acquisition. The criminal terrorist attacks on USA, in 2001, on the World Trade Center followed by the anthrax mailings emphasized the vulnerability of individuals in buildings. Building targets can encompass not just government or military structures but also high profile commercial, healthcare institutions, as well structures with high density of people such as shopping malls. In addition to terrorist events unintentional chemical spills or certain infectious agents can impact individuals in buildings as well. The major route for dissemination of chemical or biological agents within a building is the HVAC system. Common to different threat scenarios direct instillation of these agents at the air intake site, dispersal in the environment (or atmosphere) followed by entry through the same air intake
