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，因为它们的生产或获取容易且成本低。2001年，美国发生了针对世界贸易中心的犯罪恐怖袭击，随后又发生了炭疽邮件，这突显了建筑物中个人的脆弱性。建筑目标不仅包括政府或军事建筑，还包括引人注目的商业、医疗机构，以及购物中心等人口密度较高的建筑。除了恐怖事件外，无意的化学品泄漏或某些传染性病原体也会影响建筑物中的个人。在建筑物内传播化学或生物制剂的主要途径是暖通空调系统。在不同的威胁情景中常见的是，这些物质在进气口直接注入，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
