Right operation of buildings with respect to indoor climate and energy consumption
Even though the technological possibilities haven’t been better for creating the right indoor climate in buildings together with low energy consumption, the overall situation is quite poor. The area is strongly interdisciplinary from organization, people competencies, operation & maintenance, focus of management – to technic and theory. The project at hand will treat all these areas and will among other disseminations bring the new knowhow into the education of MSc.and BSc. engineers and Marine engineers (maskinmestre) and also the staff working with the daily operation in practice.
The ambition of the project is to reduce the gap between the possible low energy consumption together with a good indoor climate and the actual state in buildings. The project will continue and follow up on previous projects concerning “EiSE”. Commisioning will be addressed with focus on the collaboration between project and operation departments. Concepts from Facility management will be included. However, both Commisioning and Facility management are mostly kept at a clarification and description level. Best practice of current technology will be described together with system interactions and building dynamics and general more intelligent use of online data. The cases are in the sectors of shopping centers, office buildings and to some extent municipality buildings. In the latter case the focus will be on the people who actually on a daily basis in situ are operating and monitoring the systems.
The knowhow obtained will be included in the education of civil engineers and marine engineers (maskinmestre).Furthermore vocational training of “ground floor personal” will be included. In the cases the present situation is described, actions are undertaken and the impact on energy consumption and indoor climate are registered and analysed.
DEAS estimates a saving potential at Danica’s portfolio within shoppingcentre to be 50 GWh.
From the official Danish Energy Statistics it can be estimated that approximately 18.000 GWh are consumed to operation of buildings (excluding privat and production sector). This is roughly split in 50% electricity and 50% heat. The general experience is that savings of 25% can be achieved. This corresponds to til 2.250GWhel (approx. 7% of the yearly electrical power consumption in DK).
Beside the teaching material, mentioned above, all written by experts on the specific field, three Case-studies were carried out: Energy Renovation of Lyngby Storcenter (Lyngby Shopping Mall), investigation competences building operators’ competences, daily practices and chal-lenges with respect to indoor environmental quality and finally a follow up on a control strategy developed in previous ELFORSK projects – the “EiSE” strategy. The latter is a method, where all controlled airzone temperatures are observed and an overall “decision” on energyoptimising setpunkts for cooling water, heating water and necessary pressure of the ventilation fans are carried out continuously.
The textbook will be updated after the end of this project based on the teaching experiences.
