Clim’Elioth, a proprietary eco-design tool

Exploring possibilities for optimising energy and comfort in buildings

It is designed to assess a building’s energy needs, then to suggest and optimise the various architectural and technical options through related studies. From the beginning of the design and construction phase, it is possible to evaluate buildings’ energy requirements and to make various assumptions about the possibilities of natural ventilation, air conditioning, heat exchangers, the heat recovery percentage for a double-flow heat pump, and more. This tool becomes a design guide for limiting a building’s energy consumption and needs, whether it be new or under renovation.

The Clim’Elioth software has the advantage of providing a comprehensive energy and climate approach for an architectural project in a small period of time, necessary in the early stages of design. So it saves time when it comes to establishing the potential of bioclimatic design. It is simple, fast and responsive. The software can only study one area at a time, which means that either one room or the entire building is modelled, so it provides an easy characterisation of the geometry of the building and its physical properties.

In terms of calculation, Clim’Elioth carries out an hourly assessment of the energy exchanges defined by the input data and meteorological data for the defined area, limiting itself to the needs assessment. This then results in a variety of charts used to observe the building’s thermal behaviour from an hourly to an annual basis.

In summary, the Clim’Elioth software allows for:

  • easy characterisation of the geometry of the structure and its physical properties
  • an evaluation of a building’s thermal behaviour
  • results to be processed in a relevant way
  • all kinds of parametric studies
  • an assessment of the many architectural and technical solutions of a project from an energy point of view, right from the early stages of a project

Climelioth

It is possible to reduce cooling needs and choose cooling methods with lower impacts:

  • Densifying ground vegetation.
  • Choosing materials with high albedos (limiting the absorption of solar radiation).
  • Controlling anthropogenic heat generation.
  • Reducing internal heating in buildings.
  • Facilitating access to district cooling systems
  • Developing geothermal energy on shallow aquifers and energy geo-structures.
  • Relying on “thermal smart grids”.
  • Encouraging the development of alternative cooling systems for buildings.
  • Contributing to the sharing of feedback.

The study seeks to describe solutions at several levels, from the building to the urban space, not to mention the essential awareness raising among stakeholders and users of the city.
