Energy Efficiency Management in Model Based Building Information
work package 2
The work includes four main tasks:
1. Integration of energy measurement and simulation data with BIM: aiming to clarify how energy measurements can be used for determining energy consumption and providing information about potential faults. The projects will do a comparative study on different existing software dealing with this issue. Some key questions here are
(1) how energy calculation models are designed,
(2) type of the required input parameters,
(3) what level of accuracy can be expected, and
(4) how to use measurements either as part of input or for calibration of the model. The results from task 1 will be further utilised on the other tasks.
2. Use of construction and energy performance simulation in renovation projects focusing on the use of BIM for energy and construction simulation in the industry and public sector. SMEs and public sector will be looked at specifically. The project aims to
(1) identify the scale to which BIM is used for these purposes in SMEs and public sector (municipalities) for renovation projects,
(2) identify why different stakeholders use it or why they don’t, and
(3) map the experiences they have gained. This will be accomplished by direct intervention with regional and local stakeholders, through a workshop or seminar.
3. Using BIM as tool for efficient building operation: focusing towards the operational stage of the building. This will include both buildings that are ready for renovation or are in the renovation process, as well as newly renovated buildings. Main points: (1) how is BIM used post-renovation, (2) BIM as a building management tool, (3) develop procedures on how to upgrade the BIM models, evaluate the buildings performance and determine the need for audits.
4. Dissemination and learning tools; synthesis of tasks 1.-3. Providing development of learning tools and plan for dissemination of results.
BIM based system is expected to have significant impact on the energy performance of the building during its life-time. Using BIM not only as a construction tool, but also as a managing tool, will provide a cost-effective method to evaluate, prioritize and audit coming renovation projects.
