Publication of EU GPP criteria for road lighting and traffic signals

In the context of the European collaborations that we manage via the BuioMetria Partecipativa project, in 2017 we started to follow a working group concerning the update of the Green Public Procurement guidelines for road lighting and traffic signals.

This group is coordinated by the Joint Research Centre (from its Sevilla, Spain, facility), and in the past 18 months is saw the active presence of several of the light pollution experts we know, together with experts from other domains.

Two days ago through the working group’s mailing list we had news that the results of the activity are available. Please see below the announcement. For more information:

We are delighted to announce that the EU Green Public Procurement (GPP) criteria for road lighting and traffic signals have been published.

Although lighting systems in general are great examples of potential win-win scenarios for the environment and public budgets, the setting of appropriately ambitious criteria for energy efficiency and durability has been a particular challenge due to the rapidly evolving nature of LED technology. Thanks to detailed input from some of you, including an in-depth analysis of the LightingFacts database using data from the last 6-7 years, it has been possible to present a tiered approach to minimum luminaire efficacy requirements in EU GPP criteria for the next 6 years.

A novel and ambitious approach towards tackling the issue of light pollution has been taken, with requirements on both upward light output ratios and blue light emission being set. The emission of blue light is a particular concern with some LED lighting products and we are pleased to be able to promote a specially tailored metric for blue light (the G-index) which is much more precise and reliable than the commonly used CCT metric. We must say that this was only possible thanks to the previous work of a dedicated group of stakeholders on this particular matter, so a special thanks to those of you involved in the light pollution criteria.

We also have tried to emphasise the importance of durability aspects with LED lighting and to try to shed light (pun intended) on the general misconception that all LED lighting products have excellent durability. There are different quality specifications for different LED chips and durability depends a lot on the quality of the electrical components and appropriate luminaire design, not just on the lamp itself. In line with circular economy principles we are promoting more durable and recyclable products that are correctly labelled to aid in their future replacement, upgrading or disposal.

Feb. 7, 2019 branobag: have a coffe break thinking about that dress

[first edition, Aug. 17, 2012. The Italian version of this post has a lot more context explaining the title. The 2019 edition has a first pass on an Italian cover for the song, as a work in progress by the Metalliferous Hills Jug Band]

Old enough / Matura

You look pretty in your fancy dress | Con quel vestito sembri un bel bijoux
But I detect unhappiness | Pero’ mi pare che tu sia un po’ giu’
You never speak so I have to guess | Te ne stai zitta e io ti dico: “su’”
You’re not free. | …non sei li-i-i-bera…

There, maybe when you’re old enough | Ehi, quando poi sarai matura
You’ll realize you’re not so tough | Scoprirai che non sei una dura
And some days the seas get rough | Col mare grosso non sarai sicura
And you’ll see | vedra-a-a-i

You’re too young to have it figured out | Sei una bimbetta, non ci hai ragionato
You think you know what you’re talking about | Credi di sapere del futuro e del passato
You think it will all work itself out | Credi che alla fine sara’ tutto aggiustato
But we’ll see | ma chi sa-a-a

When I was young I thought I knew | Da giovane ero sicuro di me
You probably think you know too | probabilmente lo sei anche te
Do you? Well do you? | lo dici te…lo dici te..
I was naïve just like you | ero ingenuo, come te
I thought I knew exactly what I wanted to do | pensavo di sapere che fare di me
Well, what’s you gonna do? | be’, ora dillo te!

And how have you gotten by so far | e come hai fatto ad arrivare sin qua
Without having a visible scar? | senza nemmeno una fe-rita?
No one knows who you really are | nessuno sa chi sei in verita’
They can’t see | non lo ve-e-e-dono

What’s you gonna do (what’s you gonna do) | ora che farai (ora che farai)
What’s you gonna do now | o-o-ra
What’s you gonna do (what’s you gonna do)
What’s you gonna do now
What’s you gonna do (what’s you gonna do)
What’s you gonna do now
What’s you gonna do (what’s you gonna do)
What’s you gonna do now
What’s you gonna do now

The only way you’ll ever learn a thing | il solo modo per imparare
Is to admit that you know absolutely nothing | e’ ammettere di ignorare – tutto
Oh nothing | oh, tutto
Think about this carefully | tieni questo bene a mente
You might not get another chance to speak freely | potresti non poter riparlare liberamente
Oh freely | liberamente

Maybe when you’re old enough | forse quando sei matura
Maybe when you’re old enough
Maybe when you’re old enough
You’re not free | non sei li-i-bera
You’re not free

The BuioMetria Partecipativa project: from the Farma Valley (inner Southern Tuscany) to the HORIZON 2020 programme.

The BuioMetria Partecipativa was born in Spring 2008 in the woods of the Farma Valley, in Southern Tuscany (half way between Siena and Grosseto). While the project as a “local” approach among its priorities, since its first steps it was aiming at national and international connections:

  • Since 2008 the project managed several international relations. Part of these are documented at
  • Between 2009 and 2011 the progress of the project was presented in the main European event concerning night sky protection and promotion of night sky (the IDA Symposium)
  • Between 2013 and 2016 the BuioMetria Partecipativa project represented Italy in the management committee of a European research network funded by the COST programme of the European Union (the Loss of the Night Network), together with some 18 countries, and with about 40 participating organisations. In the context of this project we also promoted Tuscany as the location for one of the sensor intercomparison campaigns and one of the network meetings (in collaboration with CNR IBIMET). This was in March 2015, and was covered by national media (Radio 24).
  • Between 2017 and 2018, BuioMetria Partecipativa had a small grant from the Stars4all HORIZON 2020 project. Thanks to this, we were able to launch events in addition to those that we routinely manage. We also promoted the co-funding of an International symposium on the protection and the promotion of night sky . This was held on the island of Capraia in September 2018 and represented, as far as we know, the first event of this type held in Italy, at least since 2008.

On December 10 and 11, 2018, the final meeting of the Stars4all project was held in Madrid, Spain. The project had partners from Spain, Germany, United Kingdom, Belgium, and Italy. In this context, Andrea Giacomelli presented a summary of the main activities conducted during the past two years, especially in collaboration with the communities of Torniella, Piloni, Scalvaia, the National Research Council’s Institute of Biometeorology, the University of Pisa and the professional photographer Federico Giussani.

The Madrid meeting, which BMP coupled with an independently organised outreach event on the evening of Dec. 11, was just before the third Farma Valley Winter Fest and the annual assembly of the Tuscan Amateur Astronomer Associations. Our presence in Spain was the opportunity to launch some initiatives which took place in Tuscany at the end of Fall 2018, and to announce a line of activity which we will work on between February and mid-June 2019.

Dec. 1, 2018 – Bar Cerveceria Sidi – Waiting for the Farma Valley Winter Fest with BuioMetria in Madrid

The Madrid meet-up with the info point about  BuioMetria Partecipativa , waiting for the Farma Valley Winter Fest,  is on Dec. 1 at 9PM at Bar Cerveceria Sidi, in Calle Colón , angolo Calle del Barco.
Pibinko will have a (small) desk space with outreach material to explain, first of all, the light pollution issue…then we will see. We plan to close the info point by midnight.

The first announcement of the event, made yesterday, started flowing through the capital, leading to the creation of long lines of people interested as seen below:

Madrileños lining up waiting for tonight’s outreach event at 9 PM, Sidi Bar….not (but the place we found is interesting).

Waiting for the Farma Valley Winter Fest in Madrid

As per the promotion plan of the Third Farma Valley Winter Fest (in Southern Tuscany Dec 14-16, this year also hosting the Tuscan conference of amateur astronomer associations, including some international guests), we have an event scheduled for tomorrow (Saturday, Dec. 1, 2018) in Madrid, Spain.

The situation is kind of fluid, but not chaotic: at present the venue and the time are not yet defined. However this is an event taking shape a long way from home, and in a city where I was last time in 2004. So bear with me if some details will arrive last minute. For the moment I can say the event will be after 8PM.

Should you be in Madrid, and interested in participating, please write to to have more details as soon as they are available, or check the section during the afternoon of Saturday.

If you are interested in the Farma Valley Winter Fest (Southern Tuscany, Dec. 14-16 2018), please check:  , noting that not all content is available in English, as per this note.

Meanwhile, some cool live music (in addition to the  Seguridad Social, branobag).

The Autumn BuioMetric Campaign (news by, Nov. 13, 2018)

Entering the Valley that’s not there

We are set. Are you? The 2018 Autumn BuioMetric Campaign has started.

You are invited to events and initiatives which will lead us to the Third Farma Valley Winter Fest (Southern Tuscany) on Dec. 14-16, for three days of pici, love and music.


Several of the historical readers have been asking for a new branobag season. We can do this, but in a light version, as a soundtrack for your reading. As a starter I propose “Stay With Me” by The Faces.

News by on culture, environment, and open innovation (Oct. 29, 2010)

In the past week we put some time and energy to review various ongoing initiatives (I say “we” referring to some folks I collaborate with).
At the end of this exercise, we came out with a schedule which will bring us in seven weeks to the Third Farma Valley Winter Fest, with an outlook to June 2019.

I don’t mean to elaborate too much. The first upcoming event, as far as I and other colleagues are concerned, is the first official live show by the Metalliferous Hills Jug Band at the Sassofortino Chestnut Fest, in Southern Tuscany. I am particularly glad because a cousin of mine from Ireland will be on stage.

For residents in Southern Tuscany, the  Sassofortino Chestnut Fest is one of the interesting and important events, animating their  territory out of the Summer season. For non-residents, this might look like yet another country-style joint. We invite you to come on the evening of Nov. 1, and we can decide together what it will be.

To start getting a feel for the upcoming season, you might want to review some of the past news from the blog, and take a peek to the calendar, which will be updated weekly through the end of the year.

Moving away from the daylight saving months, we move into a different phase…possibly nightlight saving?

La serra del Montsec és una serra calcaria de més de 40 kilòmetres de longitud a les comunitats autònomes de Catalunya i Aragó al nord-est de la Península Ibèrica. La part catalana inclou al voltant de 20 municipis a les comarques del Pallars Jussà i la Noguera.

Aquesta área mostra uns paràmetres excel·lents pel desenvolpumant d’activitats al voltant de l’astronomia i els cels foscos. Per aquest motiu el Govern de Catalunya va promoure la creació i desenvolupament del Parc Astronòmic Montsec com una eina per ajudar al desenvolupament econòmic de la regió. Aquest impuls va donar una oportunitat per aturar la pèrdua de població i la creacio i millora de noves infrastructures turístiques vinculades al cel fosc i a les activitats astronòmiques.

L’any 2013 més de 1700 km2 van ser declarats com Destinació Turística Starlight i una part d’aquesta àrea va ser també Reserva Starlight gràcies als seus fantàstics paràmetres de cel nocturn i a les accions dutes a termes en el teriirotri per a preservar-lo.

Des del 2012 es van realitzar els primers anàlisi d’impacte econòmic i social, per exemple els resultats mostrats pel procés d’evaluació i diagnosi pel disseny del ‘Pla de Desenvolupament Sostenible del Turisme Montsec 2020’ [SomMontsec 2012]. L’any 2014 un nou estudi es va realitzat sobre els visitants del Parc Astronòmic Montsec i com contribueixen en l’economia local i en les activitats alternatives a l’àrea del Montsec. Aquest estudi del 2014 es va resvisar l’any 2017 amb les noves dades de visitants i paràmetres econòmics actualitzats.

Aquests estudis ens mostren importants resultats sobre la millora de l’àrea del Montsec. Per exemple el nombre d’allotjaments s’ha doblat en un dècada, l’aturada de la pèrdua de població a l’àrea o l’estimació d’uns 2 milions d’euros d’activitat econòmica generada al territori pels visitants del Parc Astronòmic Montsec.

Montsec is a calcareous mountain range more than 40 kilometres long in the regions of Catalunya and Aragon in the north-east of the Iberian Peninsula. The Catalonian part includes around 20 municipalities in the counties of Pallars Jussà and La Noguera.
This area showed excellent parameters to develop activities around astronomy and dark skies. For this reason the Government of Catalonia promoted the creation and development of Parc Astronòmic Montsec as a tool to help in the economic development
of the region. This development gives the chance to stop the loss of population and the creation and upgrading of new touristic facilities related to dark skies and astronomical activities.
In 2013 more than 1700 km2 were declared as Starlight Touristic Destination and part of this area became Starlight Reserve thanks to its wonderful parameters of the night
sky and the actions taken in the area to preserve it.
Since 2012 the first’s analyses of the economic and social impact have been done in the area. For example the results shown by the evaluation process for the development of the ‘Pla de Desenvolupament Sostenible del Turisme Montsec 2020’ [SomMontsec 2012] as strategic plan for tourism in the area. In 2014 a new study was done studying the visitors of Parc Astronòmic Montsec and how they participate in the local economy and in alternative activities in Montsec area. This 2014 study has been updated with 2017 visitors and economy data available.
These studies give us important results in the improvement of Montsec area. For example the number of accommodation facilities has been doubled in the last decade, the stop of the loss of population in the area or the estimation of close to 2.0MEuros of economic activity generated in the area by the visitors of Parc Astronòmic Montsec.
