What Is a Smart Building
A smart building (Smart Building) is a building that uses IoT sensors and automated systems to optimize: energy consumption, comfort, security, and operational efficiency.
Components of a smart building: BMS (Building Management System) — the heart of the smart building, it integrates all systems; HVAC (heating, ventilation, air conditioning) — the largest energy consumer; lighting (automatic based on occupancy and daylight); access and security; elevator monitoring.
IoT in Real Estate: Sensors and Data
IoT sensors collect data: occupancy sensors (occupied/vacant — optimize HVAC and lighting); CO2 and air quality sensors; consumption meters (electricity, water, heat); temperature and humidity sensors; visitor counters.
Data → analytics → actions. Example: CO2 sensors show that the conference room is constantly occupied, although according to bookings — only 3 hours. Optimization: eliminate booking requirement, manage HVAC based on actual occupancy.
ESG and Smart Buildings
ESG agenda (Environmental, Social, Governance) creates huge demand for "green" and "smart" buildings. Tenants are willing to pay a premium for certified LEED/BREEAM/WELL buildings. Investors — evaluate ESG risks (energy transition risk).
Potential savings: smart HVAC system — 20-30% energy savings. Occupancy-based lighting — 50% savings. ROI from smart technologies — 3-5 years.
Digital Twin of the Building (Digital Twin)
Digital Twin — a virtual model of the physical building, synchronized with real-time actual data. Applications: scenario simulation (what happens if you change the HVAC schedule?); predictive maintenance (forecast equipment failure before breakdown); real-time optimization; renovation planning.
Practical Assignment
Office building (15,000 sq.m, tenants — corporate clients). Current problems: high electricity bills, tenants complain about uncomfortable microclimate, access management is difficult. Develop a smart building plan: (1) What sensors to install? (2) Which BMS system to choose? (3) What is the expected savings? (4) How will the investment pay off?
