CARLOS SILVAIST- LISBON

• IST Taguspark Campus• Co-creation process• IEMS measures• Baseline results• Savings • Working timeline

LISBON PILOT Presentation structure

• IST – largest engineering school in Portugal• 10.000 students• 900 faculty members• 400 employees• 3 campi

• IST - Taguspark campus• 1100 students (ICT oriented degrees)• 100 faculty members• 100 employees• 1 building from 2009

• 30,000 m2

• BMS (HVAC and Lighting)

LISBON PILOT Taguspark

Goal: minimize energy consumption and maximize

user comfort through an intelligent interaction

between users and BMS

Approach: Test different platforms and levels of

interactions in different locations

Approach:

• Periodic Baseline Period Consumption / Periodic Test Period Consumption

• Model during a Baseline Period with Predictor Variables in a regression equation

• We may use control groups

LISBON PILOTExpected savings

Reference: at least 15% from previous projects

• Behavior user transformation only

• Maximizing Comfort and minimizing consumption maybe conflicting goals

• Rebound effects are expected (up to 20%)
