Overall site planning

The Climkit energy management system covers the various needs related to energy flow management on a site. Depending on the building configuration and intended uses, a project may concern a single energy flow or combine several.

This article presents all the solutions offered by Climkit as well as the main associated technical installation options. It serves as a project planning support to quickly identify relevant elements and structure the installation consistently.

Solutions can be deployed independently or combined according to site needs. This flexibility allows for adaptation of the installation without unnecessary complexity.

Climkit Solutions

A Climkit solution corresponds to the implementation of all the necessary elements for the management of a given energy flow on a site.

It combines hardware, software functionalities, and commissioning services, potentially supplemented by operation services.

Each solution enables the measurement and control of consumption, ensuring its equitable distribution and individual billing among the various occupants and consumers.

For each solution, a list of preliminary questions serves as a basis for technical reflection and allows for anticipation of points to clarify during project preparation.

If there is any doubt regarding the configuration to adopt or compatibility with an existing site, prior consultation with Climkit allows for validation of a principle diagram and avoidance of later adjustments.

The fictional project Le Chemin des Sourires concretely illustrates the implementation of Climkit solutions in a residential building.

Communication with the Climkit Gateway

All Climkit solutions require the Gateway to communicate with the various installed equipment, particularly meters and charging stations.

Preliminary Questions

  • Is a wired internet connection available on site, or should a Climkit 4G router be provided?
  • Is there 4G signal in the electrical room, or should an extension cord and/or exterior antenna be provided?
  • Are there multiple buildings on the site and several electrical rooms? Can they be interconnected by a bus or Ethernet cable?
For more details and answers to these questions, see the Climkit Gateway connection diagrams

Electricity Management and RCP

In a building equipped with a photovoltaic installation and constituted as a Regroupement dans le cadre de la consommation propre (RCP), Climkit ensures complete management of produced and consumed electricity by connecting the various meters to a Climkit gateway to measure, distribute, and visualize energy flows.

This approach allows for optimized collective self-consumption, while ensuring fair billing for energy used. Each resident can monitor their consumption evolution in real time on the platform.

The principle relies on private electricity meters connected to the Gateway via an RS485 communication bus and the open Modbus protocol:

Self-consumption Optimization

When appliances such as water heaters, heat pumps, or charging stations use locally produced photovoltaic energy, the Climkit Optimization option increases the self-consumption rate by controlling certain appliances based on surplus solar energy production.

Installation Examples

Site in RCP including private meters for apartments, common areas, photovoltaic production, and general grid input in series with the DSO input meter.

Site in RCP with distribution board and its private meters for apartments and common areas, and an input board with Climkit private meters and DSO input and photovoltaic production meters:

Meters are connected in series to the Climkit Gateway via an RS485 communication bus.

Board with Climkit meter installation on existing DSO meter positions using the Climkit T-Box kit (DIN plate and casing):

Preliminary Questions

  • Is electricity management planned, for example within the framework of an RCP?
  • What is the number and type of meters to be provided?
    • General electricity grid input
    • Photovoltaic installation(s)
    • Dwellings / apartments
    • Ancillary rooms, commercial spaces
    • Common areas
    • Other common areas such as parking
    • Electric vehicle charging stations
    • Battery
    • Other surfaces
  • Which meters are direct (<80A)?
  • Which meters are indirect with Current Transformers (CT)? What is the amperage for the CTs?
  • Are the meters integrated into the electrical panel, or are they planned to be installed in the existing DSO meter positions?
  • Is a storage system (battery) planned for installation?
  • Can self-consumption optimization be planned by controlling the heat pump or the water heater?

Electric Vehicle Charging Station Management

Climkit enables the installation and management of charging stations in collective car parks.

The system regulates charging power based on network capacity and available energy, controls access via individual RFID badges, and manages charging billing for each consumer.

The stations communicate with the Gateway via Wi-Fi or Ethernet using the OCPP protocol:

Flat Cable and Wi-Fi

Climkit recommends a basic infrastructure consisting of a flat cable and a Wi-Fi network to facilitate the gradual addition of stations without major intervention on existing cabling.

Preliminary Questions

  • Is it a scalable installation with flat cable, or just a few stations?
  • What is the number of spaces that could accommodate a charging station?
  • What is the number of flat cable outputs planned in the electrical panel?
  • What is the number of stations to be provided immediately?
  • Do the stations communicate via Wi-Fi, or are they connected to the IP network via wired Ethernet/RJ45?

Thermal Energy and Water Management

Climkit ensures the reading of heating and hot water consumption in accordance with the federal regulation requirements for individual expense statements for energy and water (DIFEE).

Each dwelling or surface is equipped with a heat meter (heating) and a hot water meter, supplemented by main meters to allocate the common share and the hot water production share.

These measurements are used to establish transparent and precise statements, based on actual consumption rather than estimates or surface area.

For more details, see the list of connection diagrams for thermal energy and water

Example of a heat collector located in an individual apartment and equipped with a heat meter:

Preliminary Questions

  • Are wired M-Bus type heating and water meters planned for installation?
  • What types and number of meters are planned: hot water, cold water, heat?
  • Is the meter bus routed to a single location near the electrical panel?

Collective Laundry Management

Climkit offers a simple and reliable system for managing shared laundry rooms.

An RFID reader connected to the Gateway identifies users and activates the electrical supply to washing machines, dryers, or self-service laundry outlets.

This system integrates naturally with other Climkit solutions, allowing all consumption to be grouped onto the same platform.

Preliminary Questions

  • What is the number of laundries?
  • How many washing machines, dryers, and self-service laundry outlets per laundry room?

Electric Bicycle Charging Management

Climkit allows for the installation of connected sockets that allow residents to charge their electric bikes or scooters.

Access is via RFID badge and consumption is measured individually.

Here is a typical connection diagram:

Installations with visible or integrated sockets:

Preliminary Questions

  • What is the number of bicycle rooms to be equipped?
  • Is the bicycle room inside or outside?
  • What is the number of sockets?
