Administrative Post Scriptum
Einatmen 1 :: Bildung Biodigitale
Bildung BioDigitale = humanism + digitalisation + ecology
Goal 1: Establish a bridge between organic (carbon-governed) and digital (silicon-governed) realms
Goal 0: Survive
Method: Education
A Digital School ?
desktop PCs,notebooks, tablets, smartphones, raspberry PIs & IoT devices, GPUs, beamers, displays, audio (amplifiers, active speakers, broadcasting systems), interactive whiteboards, fiber optic adapters, routers, switches, hubs, WLAN access points, antenas, printers (including plotters, 3D printers, lasercutters, CNC cutters etc.), augmented / virtual reality environments, surveillence & security setups, different kinds of "smart" sensors and controllers, power supply and power management units, TPUs, ASICs, servers, automats, robots etc.
Carbon-Neutrality
* https://dictionary.cambridge.org/dictionary/english/carbon-neutral
If a person, organization, event, etc. is carbon-neutral, it does things such as planting trees to reduce carbon dioxide by the same amount as it produces it.
die Energiebilanz :: operational costs
UdK Medienhaus power consumption in 2018
| Electricity | 141 MWh |
| Heating | 1086 MWh |
*data provided by UdK's Referat für Gebäudemanagement
Greenhouse gas equivalent of 1227 MWh
= cca 862 tons of CO2 =
sequestrable by cca 14000 tree seedlings grown for 10 years
Potential gain by installation of photovoltaic panels on south-oriented roofs of Front and Back buildings of UdK's Medienhaus
| Annual energy yield | 262MWh |
| Annual CO2 avoidance |
184 t |

Das Ergebnis dieser Bilanz:
das System ist aus der Balanz.
wasted energy (a "multiple-with-time" formula)
Rhytmic devices & services
"A circatemporal device (or service) is defined as a device (resp. service) with pre-built rhythms. Ideally, both software and hardware behind such devices (or services) are designed & optimized to be automatically turned “on” and “off” on a regular basis."
a circadian device (a "digital Primer" example)
"... The major boot-up time of our current Primer prototype is at 14:30 ... Consequently, the Primer is active for an hour, inviting the Child to perform whatever activities she finds appropriate (e.g. reading, writing, speaking, listening, arithmetics etc.).
After one hour, the artefact shuts down on its own ..."

Raspberry Pi Zero + wittyPi + optimized OS + e-ink + "small-data" + solar
Eutark devices
Hromada (2019) Circadian and eutark reduction of the energy trace of a digital school. https://doi.org/10.25592/issn2509-3096.007
"We define an energy-autark (or simply "eutark") device as a device able to produce energy necessary for its own operation."
A little note
Once loaded, the content displayed by an e-paper (e-ink) device can transfer information (or even teach) without consuming any energy.
Raising awareness
"... at the end of the day, it may be the case that the very design of the educational medium shall motivate a pupil to turn off the light when leaving the classroom and optimizing the thermostat settings when leaving the school.
An auto-catalytic spark of responsibility has been ignited and gigawatthours of energy can be, in the long run, saved."
Eutark buildings and CO2-neutral campus
trees instead of lawns
plants, plants, plants
photovoltaics
heat the building with machine-generated excess heat
heat pumps, heat pumps, heat pumps
algae photobioreactors
carbon-sequestrating paints ...
P.S. Verwaltung
"Repair cafes", "Nachhaltigkeitbureau", "Energieberatung" u.s.w., das alles ist schön und nett und besser als nichts.
Aber der Klimanotstand ist schon da.
Was wird also dringend gebraucht sind nicht nur Berater(innen) sondern Inspektor(innen), Beauftragte und Referate mit Befugnis zum Handeln.

Auf jedem Campus und in jeder Schule. ASAP.
