Dynamic energy simulations at district level.

PowerDIS is used to generate detailed simulations of the energy demand and consumption of a district ranging from a dozen or so to several hundred buildings, whether extant or awaiting construction and/or renovation, and to compare energy strategies in the early (pre-design) stages of a development project.

Software aims

  • evaluate the energy demands of a district and formulate scenarios for the impact of thermal renovation campaigns;
  • calculate district energy consumption (particularly electricity, gas and heating);
  • guarantee reliable scenarios for the energy dynamics of a project (building demands and consumption by energy systems including heating and cooling networks) at different stages of construction or depending on the different variants selected.

Target users

PowerDIS aims to assist its users in deciding on the energy strategy to be deployed for a development project or district. It is designed for:

  • planners, via their PMA/design office, at the time of energy supply opportunity and pre-feasibility studies (heating and/or cooling networks, decentralized systems);
  • local authority teams keen to develop their energy strategies in target areas of their territory;
  • R&D teams as part of more detailed analyses.

Use case

PowerDIS can be used for:

  • diagnostics of district energy demand, master plans for heating and cooling networks (SDR) and for energy (SDE), studies of R&RE supply (SRADDET and PCAET);
  • calls for bids (planner, PMA, operator) during the initial phase of reflection on the energy supply strategy for the project;
  • forward-looking, pre-feasibility or sensitivity studies on district energy demand and consumption (for design offices, planners or industrialists and R&D teams).

Value added

Using a site plan, localization and possibly a preliminary study of energy reservoirs in the vicinity of a project, PowerDIS can be used to evaluate and compare the different energy strategies that could potentially be implemented.

PowerDIS has the following advantages over existing software:

  • its interface is intuitive, developed in collaboration with a group of professional users from various Efficacity members;
  • the cross-referencing of geolocation data from the IGN TOPO® database and the Sirene® database saves considerable time when modelling a district;
  • linking the simulation of the energy demand and energy consumption of energy systems and networks saves time and improves the reliability of the end results, by avoiding the need to rely on distinct methods and software tools;
  • the simulations are carried out dynamically at hourly intervals over a year, so that detailed power and energy analyses can continue to be made at different periods of the year, thereby avoiding the over-sizing of energy systems during the design phase.


  • automatic import of shapes, uses and years of construction for existing buildings, and drawing of projected building shapes;
  • auto-complete function for building thermal properties and option to personalize envelope characteristics (level of insulation, glazing ratio) and building use scenarios (setpoint temperatures, hot water and ventilation flows, internal inputs):

  • evaluation of energy demand at hourly intervals, results displayed in map and timeline forms;
  • entry of HVAC and heating and/or cooling network systems, generation of optimal network routing, sizing of network piping lengths and diameters;
  • year-long simulation at hourly intervals of energy system dynamics, display in map and timeline form of results for buildings, for the network (heating and/or cooling) and for each means of energy production;
  • simulation of heating and/or cooling networks meshed with multiple production points.
