How to help building managers to permanently reduce energy consumption when they have no specific professional skills in this area?

In many fields, a building’s occupants are not the ones who pay for the energy they consume or the ones managing and maintaining energy production facilities – but they are nevertheless in a position to behave eco-smartly and consume less, i.e. manage energy more efficiently and reduce their buildings’ environmental footprints.


The building manager (or the head of the organisation in a public building) has a vital role to play here. The key is to turn raw data reflecting energy consumption (which typically only reaches specialists) into tangible information that anyone can instantly understand, and to encourage building occupants to adopt smart behaviour patterns, in their everyday lives and jobs, as a habit.




  • Use case and experimentation field

  • Data sets

  • The business opportunities

  • Results

Today, many building managers and organisation heads working for Paris City Council have no information about their building’s consumption or how it is evolving over time, or direct incentives to reduce that consumption. The leads at this point include extracting and displaying consumption figures in a way that non-specialists will readily understand, and tailoring information to each specific situation:


– Displays may be combined with other data besides energy consumption and relating more specifically to building managers’ everyday duties, in order to encourage them to use these insights on a permanent basis


– The displays may also be combined with leads to help them reduce consumption

The following data sets are available to use for this challenge:

– The City of Paris makes available the data from the supervision of boiler rooms in about a hundred buildings including electrical and heat consumption (gas or steam).


– The City also supplies indoor temperature, presence and hygrometry readings coming from gyms, day-care centres and other facilities.

Paris City Council has pledged that 10% of the reduction in its energy consumption, in all the buildings it manages (arrondissement city halls, day-care centres, schools, gyms), will stem from behavioural changes. It may therefore use the developed solution to that end. More generally, the target could include property managers in a variety of areas where building occupants do not pay energy bills directly and where the size of each building does not justify employing full-time maintenance staff (e.g. chain stores).


Engineering companies such as Setec may be interested in bundling products based on behavioural sciences into their solutions, to complement their existing choice of products and services.

Solution :


The experimentation focused on user research and hand by hand with the building managers, BeeBryte developed an intuitive energy management tool called « RDV Conso ». RDV Conso is composed of a dashboard and e-mail alerts, connected to real-time sensors inside in building. Thanks to it, the building managers can :


  • Know in real time and area-per-area their building’s consumption (gas & electricity) and temperature.
  • Objectify the impact of their eco-actions and the evolution of their building environmental footprint
  • Get personalized advices and recommendations, according to its weekly energy consumption
  • In the long run, receive e-mail alert to inform him of any incident or over-consumption in his building


Impact :


Participate in the city engagement in reducing by 10% its energy consumption through behavioural changes :

  • Time gained in Abnomalies identification and management of the dysfunctions for the building manager & for the city of Paris  
  • Awareness to energy issues and skills development
