BIM CASE STUDY | SCHNEIDER ELECTRIC As a result of the extensive IoT architecture, equipment in the building can be controlled based on multiple criteria. TPle is smart-grid ready that is to say the technical installations, associated with the EcoStruxure system, can be energy flexible by shifting consumption times. The system will, for example, make it possible to optimise the cost of energy by using dynamic pricing and load shedding or through demand-response operations, whereby the building is taken off-grid at timesof peak electricity demand. The system could even be used to optimise the buildings carbon contribution. This flexibility will allow the consumption of energy to be shifted to times when energy is cheapest, which will help to lower our energy bill, Lack says. The BIM model being used by the facilities manager to operate the building requires far more detailed information than the IoT model needed by the buildings users. The project has taught us how best to specify the BIM model, because the model required by the user is different from the one used by the FM, says Lack. Tracking behaviour Candidly, he adds that it has been difficult to see the benefits of BIM for the construction phase of the TPle project, because five years ago when the project started the contractors were not fully BIM conversant. It was also a steep learning curve for all those involved: You cannot expect savings when you do your first BIM project, says Lack. However, he believes the situation should improve now that ISO standard 19650 defines information management within a BIM design and construction environment. Now that the TPle building has been completed, Schneider is studying it in TPle is smart-grid ready and can be taken off grid during peak electricity demand operation, to understand better the algorithms and features needed to optimise its energy consumption. With this dynamic model, we have the capacity to track the actual behaviour of the building and to compare it with the virtual building, to see if implementing different control scenarios can improve performance. But will it reach the target of 45kWh m-2per year? Its still too early to tell, because we need at least a years operationtovalidate the model to see if it isgood, says Lack. Information from the operation of TPle will inform construction and operation of the second building, work on which is already under way. The aim is for it to have an annual energy consumption of just 37kWhm-2per year, roughly a quarter of the office average energy consumption in Europe not bad for abuilding in a city such as Grenoble, where the average temperature in January can dip below freezing.
