Comparison of traditional building no 1 and building no 2 raised according to green building principles (own research)
| Factor | Results |
|---|---|
| Initial costs | The construction costs of a sustainable building were approximately 20 % higher than a traditional building |
| Energy saving | A green building reduces energy consumption by up to 30 % – 50 % compared to a traditional building |
| CO2 emissions | The use of energy efficient technologies in a sustainable building is estimated to lead to a 35 % reduction in CO2 emissions |
| Savings from investment | An investment according to green building principles can pay for itself within 5–10 years through lower operating costs |
