From the list of Cities requirements targeting their building portfolio and priorities for retrofitting, the complete vision and specifications of the TRIBUTE project will be defined.

Human behavior can significantly influence building energy consumption. WP2 investigates into human activity detection and their effect on building energy performance.

This Work Package aims at identifying key discrepancies between the state of the art design process BEPS and actual buildings. In the situation where phenomena are already adequately modelled, key parameters will be identified. Where models are too simple, more relevant models will be developed.

This work package will propose an wireless communication architecture. This architecture will allow the project to deploy wirelessly connected sensors and use them to collect the necessary information for the performance analysis and comparison with the model. This infrastructure will ensure that many types of connected sensors can be used by interfacing heterogeneous networks to a common database.

This WP targets the development of a building real time key parameter identification protocol and tool based on the sensor toolkit defined in WP3. Combined with occupancy models of WP2, this tool will allow energy gap reduction and accelerated performance assessment. It will insure a feedback to the i-BEPS, when being deployed on a building. It will be fed by the measurements provided by the wireless sensor network. It will be the base for retrofit option.

Using the tool and methodology developed in WP5, this work package will develop a tool that will be able to propose and evaluate retrofit options to the building’s stakeholders (owners, inhabitants, etc…). Retrofit options will mostly include improvements of building constitutive elements performance (walls, roofs, insulation, windows) but will also consider HVAC and renewable energy systems as well as the set-up of novel energy control strategies.

Based on sensor measurements, novel energy flow management at building level will be proposed as well as building health monitoring techniques. Analytics and advanced data management tools will help to identify new solutions for reducing the gap. Involve the building occupant, by a persuasive user’s interface.

Aims at validating the TRIBUTE development on the selected test sites. Necessary sensors, communication and control hardware will be installed on test sites. I-BEPS performances will be assessed, in terms of energy performance prediction and retrofit advice, while the BHM tool will be assessed in terms of fault detection. On-site deployment of the tools will be carried out taking into account the occupant’s feedback.

This work package runs in parallel with the whole project, covers training activities and will disseminate the most important results from previous work packages and ensure the exploitation of the TRIBUTE results. This work package is also dedicated to contribution to new and on-going international standardization efforts on the energy efficiency of buildings.

The objective of this task is to assure that the results of the project will be disseminated to the European research and industrial community, will also target all stakeholders of the smart city value chain and will assure an on-going communication between the general public, municipalities, housing associations, architects and energy consultants etc. on one side and partners of the project on the other.
