Camera Circle is a Sketchup extensionto spiral around your model around some points, radius and distance evolving between a starting and an ending position. You make visualize the show or generate images to prepare a video.

A nice example on the Sketchup model of Arecibo radiotelescope. Sketchup model by Brian C. on the 3DWarehouse.

Colors represent the number of hours of direct sun on surfaces calculated with SunExposure.

Camera Circle

You can freely download Camera Circle.

Camera Circle is a Sketchup extension that allows to visualize your model by rotating around it and to generate images to make a video.

The principle is simple: For your current view, Camera circle rotates the view around origin point to visualize the model from various angles.

Sky View Factor

You can freely download the SkyView Factor within DL-Light and buy DL-Light license to enhance functionalities.

This Sketchup extension allows to calculate the SkyView Factor for the various surfaces of a Sketchup model.

The view of the sky from inside spaces for architectural projects or from outside spaces for urban projects plays a key role in the pleasantness of spaces.


 

Keeping the same user experience principles as the other modules of DL-Light, SkyView Factor allows with one view to understand the view of the sky for all spaces via a visualization in False Colors.

SunExposure

You can freely download SunExposure on this page and buy a SunExposure license to enhance functionalities.

SunExposure is now part of the DL-Light suite.

SunExposure SketchUp extension calculates the number of hours when direct sunlight strikes SketchUp model’s surfaces for a given period.

SunExposure is adapted to standard SketchUp interface, and is comfortable and easy to use. Still it provides various levels of details both for input and output, and even demanding users can find it useful in their work.

SunExposure works on Windows and OSX.

It is available in English and French.

Unlike a simple shadow visualization, SunExposure takes into account the climatic data of the site and calclate for a whole period of time the daily average or total exposure to sunrays.

Hence, it is an grea tool to evaluate the need for protections of glazed surfaces and their efficiency.

SunExposure extension is oriented towards early project design phases, when level of details of future building is rather low, and when only basic information about building environment, position and geometry are defined.

SunExposure

Sketch project for Faverges, arch. B. Clerget, LineaireA

Information about exposure to the direct sun can influence on important decisions related to building lighting and thermal strategies:

  • Selection of facade materials – in accordance with their light sensibility,
  • Suggest position of windows on the facades,
  • Suggest which parts of the building need special sun protection, to avoid glare or overheating
  • Evaluate the efficiency of proposed sun protections and compare the effect of various sun shading alternatives proposed for the building,
  • Suggest areas on the facade that should be insulated to prevent overheating or over-cooling of the building. Visualize potential risks of overheat,
  • Suggest areas of the building which can be used for passive solar heating -“greenhouse effect”,
  • Suggest best places for photovoltaic cells.

Sun exposure of a point on the facade depends on building site weather and environment (relief, obstruction buildings), selected time period and also of building shape, facades orientation and sun protections.

It is independent of materials used on facades or environment and of building interior.

Luminous Autonomy

You can freely download the Daylight Autonomy within DL-Light and buy DL-Light license to enhance functionalities.

This Sketchup extension allows to calculate Daylight Autonomy indicators for the various surfaces of a Sketchup model.

The autonomy in natural light means that a space does not require artificial light to perform activities.

Daylight Autonomy indicators have been developed and are now gaining popularity in the evaluation of the sustainability of an architectural project regarding Daylighting.

These indicators calculates the percentage of time when the architectural project is autonomous with daylighting.

Breeam

Since version 3.0.23, DL-Light integrates the calculation of Breeam requirements for minimum and average illuminance on surfaces.

To perform this evaluation, DL-Light calculates on the 3D model the illuminance hour per hour on a grid of points compatible to Breeam requirements. Then, according to space types, DL-Light calculates of the spaces of the model follow Breeam requirements and prepares a complete report.

As always, results for these requirements are directly reimported within the SketchUp model using false colors. You may then see directly which spaces follow the requirements or not for the minimum and average illuminance.

Software tools developed by De Luminae

De Luminae develops software for simulation and analysis of natural light. These tools aim at helping architects and technical offices to design and analyse their architectural and micro-urban projects using validated methods and algorithms.

See more on DL-Light website.

These tools come from our experience of more than 15 years in research, teachings and expertise on luminous ambiance in daylighting and the impact of natural light on energy consumption in buildings.

The importance of the electricity used for lighting in the overall energy consumption is more and more aknowledged in projects. However, it is our belief that professionals lack software tools able to integrate the study of daylithing within the architectural and micro-urban design.

Compared to the few existing tools, our developments aim at:

  • Providing useful information at the right time.
  • Providing precise and reliable results validated on real cases.
  • Using scientific algorithm and data.
  • Presenting the results in a graphical and synthetic way immediately understandable by professionals.
  • Adapting itself to the available data in the early phases of design.
  • Providing results displayed within the 3D model.
  • Being fully integrated within Sketchup.
  • Optimizing performances of calculation speed.

Thesse tools demonstrate our vision of design-aid of luminous anbience in daylighting.

Interpretation models and their application for luminous ambience

thumb

Quantitative information from measurements or simulations of interior luminous ambiences yields a large quantity of data. These data may be very useful to analyse the performance and comfort of a luminous ambience in design or rehabilitation and promote a controlled use of daylighting instead of artificial light. However it is necessary to interpret these data with terms accessible to architects.
The purpose of our work was both theoretical and applied: we improved data collection and interpretation methods of quantitative data on luminous ambience. We then applied these methods to design a modified luminous ambience in an existing space.
We had the opportunity to work in the cafeteria of the “Galeries du Grand Palais” in Paris.

We improved the measurement method for luminance and chromaticities on the interior opaque and glazed envelope of spaces in natural and mixed lighting (both natural and artificial). We interpreted these measures (a large number of quantitative data) in qualitative terms. On the basis on these analyses, we followed the inverse path: we expressed the concepts for modified luminous ambiences, then built these ambiences. We could verify with measurements the correspondences between our qualitative intentions and measured quantitative data.

This work gave interesting insights for the definition of criteria for the analysis of luminous ambience.
