Smart Buildings by Design: How the Fourth Trade Connects It All with the Purdue Model - Jacob Jackson

\nSmart buildings aren't just about automation-they're about integration. In today's world, HVAC, lighting, security, IT, fire alarm, and AV systems must work together seamlessly to support building performance, cybersecurity, and long-term operational goals. But too often, they remain isolated-leading to wasted energy, frustrated users, and costly retrofits.\n \n\n \nSmart Buildings by Design: How the Fourth Trade Connects It All with the Purdue Model introduces a new mindset for building professionals: integration is its own discipline-the Fourth Trade. Drawing on over 20 years of experience in building automation and operational technology (OT), Jacob Jackson presents a top-down strategy rooted in the Purdue Model that starts at the enterprise level and works down through IT, OT, and field-level systems.\n \n\n \nThis book provides practical tools and insights for engineers, contractors, architects, facility managers, and executives involved in new construction, renovations, or digital transformation efforts. You'll learn: \n \n\n \n- How different building systems interact-and why they often conflict \n- Where integration breaks down in real projects (and how to fix it) \n- How to apply the Purdue Model in reverse to align technical design with business objectives \n- Ways to reduce risk through standards like Division 25, BACnet, and structured network design \n- How to make the business case for integration to decision-makers \n\n \nSmart Buildings by Design is essential reading for anyone responsible for creating intelligent, connected, and future-ready buildings. Whether you're struggling with siloed systems or planning a next-generation facility, this book will help you build with clarity, strategy, and confidence-from Day One.\n
