As part of the RESt4GREEN, the partner Izmir Institute of Technology (IZTECH) conducted a user-focused survey to better understand the energy needs, habits, and expectations of people using campus buildings.

Building on the existing GreenBuilding Project survey, IZTECH researchers introduced additional targeted questions aiming to capture valuable insights into users’ daily routines and environmental requirements. They shared the survey with students and staff who actively use the facility and collected 50 responses. These responses helped identify important patterns in energy use and overall building performance.

🔍 Key Findings

The results highlight a strong awareness of energy efficiency among users, but also reveal a clear gap between user behaviour and building performance:

  • 92% of respondents consider energy saving important
  • 88% report that they actively switch off lights
  • However, users frequently observe energy waste, including:
    • Lights left on in empty rooms (41.7%)
    • Unnecessary heating (31.3%)

This reveals an important contradiction: although users show strong awareness and responsible habits, the building does not always operate in a way that supports these values.

The survey also indicates relatively low satisfaction with indoor conditions, as only 38.8% of occupants report being satisfied with current comfort levels.

At the same time, the findings show strong engagement and willingness to improve:

  • 70% of users want to learn more about energy use
  • Many participants also expressed interest in improving outdoor spaces with smart and sustainable solutions, such as solar-powered benches

Understanding how people interact with buildings is a crucial step toward designing more sustainable, user-centred public spaces across the Mediterranean region.
