"As solar panels heat up beyond 25°C, their efficiency decreases markedly. Green roofs moderate rooftop temperatures. So we wanted to find out: could green roofs help with the problem of heat reducing the output of solar panels?

Our research compared a “biosolar” green roof — one that combines a solar system with a green roof — and a comparable conventional roof with an equivalent solar system. We measured the impacts on biodiversity and solar output, as well as how the plants coped with having panels installed above them.

The green roof supported much more biodiversity, as one might expect. By reducing average maximum temperatures by about 8°C, it increased solar generation by as much as 107% during peak periods. And while some plant species outperformed others, the vegetation flourished.

These results show we don’t have to choose between a green roof or a solar roof: we can combine the two and reap double the rewards...

How did the panels affect the plants?

In the open areas, we observed minimal changes in the vegetation cover over the study period compared to the initial planted community.

Plant growth was fastest and healthiest in the areas immediately around the solar panels. Several species doubled in coverage. We selected fast-growing vegetation for this section to achieve full coverage of the green roof beds as soon as possible.

The vegetation changed the most in the areas directly below and surrounding the solar panels. The Baby Sun Rose, Aptenia cordifolia, emerged as the dominant plant. It occupied most of the space beneath and surrounding the solar panels, despite having been planted in relatively low densities.

This was surprising: it was not expected the plants would prefer the shaded areas under the panels to the open areas. This shows that shading by solar panels will not prevent the growth of full and healthy roof gardens.

What were the biodiversity impacts?

We used environmental DNA (eDNA) surveys to compare biodiversity on the green roof and conventional roof. Water run-off samples were collected from both roofs and processed on site using portable citizen scientist eDNA sampling equipment to detect traces of DNA shed by the species on the roof.

The eDNA surveys detected a diverse range of species. These included some species (such as algae and fungi) that are not easily detected using other survey methods. The results confirmed the presence of bird species recorded by the cameras but also showed other visiting bird species went undetected by the cameras.

Overall, the green roof supported four times as many species of birds, over seven times as many arthropods such as insects, spiders and millipedes, and twice as many snail and slug species as the conventional roof. There was many times the diversity of microorganisms such as algae and fungi.

Encouragingly, the green roof attracted species unexpected in the city. They included blue-banded bees (Amegilla cingulata) and metallic shield bugs (Scutiphora pedicellata).

How did the green roof alter temperatures?

The green roof reduced surface temperatures by up to 9.63°C for the solar panels and 6.93°C for the roof surfaces. An 8°C reduction in average peak temperature on the green roof would result in substantial heating and cooling energy savings inside the building.

This lowering of temperatures increased the maximum output of the solar panels by 21-107%, depending on the month. Performance modelling indicates an extensive green roof in central Sydney can, on average, produce 4.5% more electricity at any given light level.

These results show we don’t have to choose between a green roof or a solar roof. We can combine them to take advantage of the many benefits of biosolar green roofs.

Biosolar roofs can help get cities to net zero

The next step is to design green roofs and their plantings specifically to enhance biodiversity. Green roofs and other green infrastructure may alter urban wildlife’s activities and could eventually attract non-urban species.

Our green roof also decreased stormwater runoff, removed a range of run-off pollutants and insulated the building from extremes of temperature. A relatively inexpensive system provides all of these services with moderate maintenance and, best of all, zero energy inputs.

Clearly, biosolar green roofs could make major contributions to net-zero cities. And all that’s needed is space that currently has no other use."

i know, i know, jj is so fucking strong and she perseveres despite everything she’s gone through, i know, but fucking hell my heart is breaking over and over for her

the far away look in her eyes

the constant fidgeting to keep herself present

the way she only has the bare minimum amount of skin showing, even to where she’s covering her hands

my heart hurts for her so much and she’s forcing herself to deal with all of this alone

Just need to know… Are non-Filipino watchers of The Bear and SydCarmy shippers aware that the name of the restaurant “Kasama” is a Tagalog word that translates to “together” or “companion” in English?

I have so much fun with the galaxy background and stars it’s another redraw of a older piece I made from 2022 Meta Knight and Gala look quite the same xD while Sword, Blade, Tiff, and Tuff look different yeah I drew my au designs of thems <3💫🌟

[blazetbw-art]

I’ve come to the conclusion that I won’t have time to draw all silly little ideas I have, so I’m just gonna start commissioning people when I have the funds for it.

Sonic & my fc Syd having a chat over some nachos. Just two fools at lunch~

Commission for @blazetbw-art

Enjoy~! ✨
