Project delivery-related challenges and solutions of realizing energy efficiency
| Challenge/barrier |
| Lack of/inadequate involvement of HVAC contractors and operation/maintenance people in the project definition and design phase |
| Fragmented (i.e. divided/isolated) procurement, project delivery, and maintenance process (multiple contracts) of energy efficient systems |
| Dominance of low-price criteria in the tendering process for selecting contractors which usually have low capacity to deliver their promises |
| Solution/enabler |
| Life cycle contract |
| Collaborative project delivery model |
| Involving building services people in the project definition and design phase |
| Involvement of client and its representative (consultant) from project definition phase until the end of the project |
| Early definition of the use of the building and its spaces |
