Assess the sustainability of your urban planning project !


NEST is a plugin for Sketchup which allows a quantitivative assessment of urban planning projects since their early phases.

Its user-friendly and ergonomic interface has been designed in order to ease modelling and facilitate decision making based on the NEST results.

The plugin is currently available in french, english and spanish. NEST can be used for both new and retrofitting projets at urban scale.

How does it work?

A NEST model has to be established through different mandatory steps.

Geometric data are collected from the 3D model (SketchUp) and contextual and programing data are manually inserted by the user.

In a few clicks, a full and complete assessment of an urban planning project can be provided by NEST. NEST also allows the comparison of different scenarios in order to ease decision making.



For who ?

NEST is a tool for urban planners and private or public prime designers.

What for ?

You have an urban planning project and you want to assess or compare it with a set of urban planning scenarios ?

NEST is the tool that you need ! It eases decision making process and speeds up acceptation and consultation around your projects.

How ?

Sustainability assessment of urban planning projects is highly specific and needs to include project-specific issues. That is why Nobatek propose a two-steps methodology which aims at meeting prime designer expectations:

  • A preliminary study with the standard version of NEST. This step aims at identifying the main stakes and specificities of the project and the optimisation levers linked to the study.
  • A complete study realised with a version of NEST adapted to the studied area. A development phase is consequently needed in order to turn NEST into a specific assessment tool.



Essai urbain

Based on a collaboration with the city council of Donostia San Sebastian (Spain) and TECNALIA, ESSAI URBAIN project allowed the development of a refurbishment module incorporated within NEST. This module was tested and validated through 3 case studies choosen by the city council.



The objective of NEST TERR is to develop a specific tool adapted to the territory scale. As a first step, a preliminary study on different districts of the city of Strasbourg is carried out with the current version of NEST and then will be adapted to specific topics linked to territory assessment. Partners involved in the project are: AMUP, Eurométropole de Strasbourg, CMYT and UMR PASSAGES.


La Fab

Nobatek is currently collaborating with LA FABRIQUE DE BORDEAUX METROPOLE, which is leading the urban planning for the metropolitan area of BORDEAUX, with the objective to create more than 50 000 housings near Bordeaux. In this case NEST is used as an assessment tool and to define environmental impact levels that should be respected for the construction of the different projects. Finally, the main objective of the project is to adapt and deliver the NEST tool to LA FABRIQUE DE BORDEAUX METROPOLE, integrating all the relevant and specific parameters identified.

About NEST

NEST was initially developed during the PhD thesis of Grace Yepez-Salmon (2011), realised in Nobatek and laboratoire GRECAU of the National School of Architecture (Bordeaux, France).

Following this work, Nobatek continued the developments of the plugin through several national and international R&D projects, leading to the third version of NEST, suitable for 2015 and 2016 Sketchup versions.

Key projects in NEST history



Through different projects, Nobatek has built alliances fostering NEST development. Since 2014, TECNALIA co-develop NEST in order to adapt it to the Spanish market. Recently, the CSTB and Nobatek collaborated to link NEST and ELODIE. This new function will be available in December 2016.



Nobatek and TECNALIA's "Energy and Environment" division collaborate to develop a Spanish version of NEST but also with the objective to put in common both entities skills to fasten NEST development. Nobatek and TECNALIA have collaborated through several R&D projects in relation with NEST: ESSAI URBAIN, NEXT, UrbiLCA and OptEEmAL.



The CSTB, Centre Scientifique et Technique du Bâtiment, aims at ensuring building quality and safety and to support innovation from idea to market. The CSTB developed ELODIE allowing Life Cycle Analysis of French buildings. NEST and ELODIE geographic scales being complementary, a cooperation project was performed between Nobatek and the CSTB in order to allow the interoperability of both tools. This link will be available in December 2016.
