How are #NaturalDisaster-resistant design elements integrated into #Solarpunk buildings?

Publication date: 2023-09-02

"In Solarpunk buildings, natural disaster-resistant design elements are integrated through a combination of passive and active design strategies. Here are a few ways in which these elements can be incorporated:

1. Site selection and orientation: Solarpunk buildings are typically situated in areas that are less susceptible to natural disasters like #floods, #earthquakes, or #tsunamis. Careful evaluation of the site's history and potential risks helps in choosing locations that are more resilient. Additionally, the building orientation can be optimized to maximize #NaturalLight and minimize exposure to prevailing #winds or #storms.

2. Structural reinforcements: Solarpunk buildings embrace resilient construction techniques to withstand natural disasters. This may include reinforced foundations, earthquake-resistant designs, hurricane-resistant materials, and robust structural systems that can withstand high winds, seismic activity, or even #ExtremeWeather events.

3. #GreenRoofs and #RainwaterHarvesting: Green roofs, which incorporate vegetation on the rooftop, offer several benefits when it comes to natural disaster resilience. They can help mitigate stormwater runoff, reducing the strain on existing drainage systems during heavy rainfalls or floods. Additionally, rainwater harvesting systems can be implemented to collect and store rainwater for future use, serving as an alternative water source during emergencies.

4. Passive climate control: Solarpunk design emphasizes #PassiveCooling and heating strategies to reduce energy consumption and reliance on mechanical systems. Natural ventilation through well-placed windows, louvers, or #RoofVents can help regulate indoor temperatures. By not relying heavily on air conditioning units, Solarpunk buildings can maintain habitability even during power outages caused by natural disasters.

5. #RenewableEnergy systems: Solarpunk buildings integrate renewable energy systems like solar panels or wind turbines to generate electricity on-site. This reduces dependence on centralized energy grids, making the building more self-sufficient and resilient in the face of power disruptions caused by natural disasters. Battery storage systems can also be incorporated to store excess energy and provide backup power during emergencies.

6. Water management and flood-resistance: Solarpunk buildings employ strategies such as permeable paving, #RainGardens, and water retention ponds to manage stormwater. These features help minimize the risk of flooding and prevent damage caused by heavy rains or #ExtremeWeather events.

"By combining these design elements, Solarpunk buildings aim to create sustainable and resilient structures that can better withstand the challenges posed by natural disasters."

In a world increasingly shaped by urbanization, urban agriculture has emerged as an innovative solution to environmental and food security challenges. Among its many forms, rooftop farming stands out as a practical and sustainable option—especially in densely populated cities like New York, where space is limited. #Greenroofs #Smartfarming #Urbanagriculture

Cooling green roofs seemed like an impossible dream for Brazil's favelas. Not true! www.npr.org/sections/goa... #solarpunk #ecopunk #greenroofs #Brazil #favelas

The two lists below provide data on green roofs around the globe that is available from online resources. The first identifies the cities with the most buildings that have green roofs, while the second lists those cities with the most green roof square footage. As there is not a consistent time line for reporting data, the calendar year for the information is provided in parentheses.

Please note that in some cases, city data was only available for the number of green roofs, in other cases data was only available on the square footage of green roofs. In addition, many of the data sources do not clearly distinguish between the core city and the greater metropolitan area. Therefore, some of the number may reflect more than just the core city itself.

As always, additions, corrections, or suggestions are most welcome. Peace!

In my column this week I advocate for a carrot-and-then-stick method of incentivizing green roofs in urban areas.

Tax benefits today, penalties tomorrow.

You have to ask yourself, are we doing this or not?

"So far, tax initiatives haven’t translated into big progress. According to the NYC DoF, only 14 properties have received abatements under the city’s green roof initiative since the policy was adopted in 2011.”

I quite like these vertical installations of bifacial panels over green roofs the Norwegian company Over Easy Solar is marketing.

A fun climate adaptation update from the world of roofing construction:

-blue roofs, which are designed to retain water. New to me. One must design roof deck to hold greater loads, of course, but this is going to be a requirement across the board regardless of whether one builds a blue roof or not, just because of increased storm severity. Anyway, the water retained on a blue roof can be directed inside to water plants or, I suppose, flush toilets. Or it can be released into the storm drain system, but slowly, thus reducing local flooding. Stored water can insulate and it can actively cool a building during hot weather as it evaporates.

-green roofs, you've probably heard about them, it's a roof with plants on top! Also requires increased load-bearing capacity. Can be challenging to maintain, especially during dry weather. But the advantages: insulation and cooling, reduction in flooding and in air pollution impacts. When paired with solar panels, they can increase the efficiency of electricity generation, since photovoltaic panels don't love operating in high heat.

-the simplest roofing climate intervention: changing the color of the roofing membrane or shingles from dark to light. A simple increase in albedo can decrease temperatures in the vicinity 1 - 2 C.

Bird populations are an indicator of ecosystem health. Birds are in decline worldwide primarily due to the destruction and degradation of their habitat by humans. By design, green roofs can be planted to feed and shelter birds. This article reviews how green roofs have been planted to recover habitats for feeding birds. #Birds #Nature #Environment #greenroofs

That's nice - some new houses in #Hammersmith with some #greenroofs, but I wonder how they can get up there to mow them?

... wait a minute.... that looks like #astroturf !

#greenwashing :(

@metacat I will be establishing a green roof in the next few weeks. I plan for thyme and oregano to be part of this, lots of cuttings taken #thyme #Oregano #Greenroofs

#Blueweed #meadows fascinate me. The #flowers of blueweed rise from red bulbs into blue #blossoms (attached photos), and they ripen in two steps, first the male parts become fertile, only then the female parts, a phenomenon that is called #proterandric. The species is used for #greenroofs, important in #globalwarming times, see paper of authors A. Latini et al. (2022).

I have acquired nearly all the materials needed to build a green roof bin shed at the weekend. Rather than splash out on sedum turf, I am raising my own and adding thyme and oregano to the mix. The cuttings might not be ready, alas .. There's Sedum hispanicum and Saxifraga urbium being grown elsewhere. #Greenroofs #sedum #thyme #oregano #ajuga

… trying to explain about the #WaterProblem in #NYC

This city has all kinds of crags and holes not calibrated for this much water all at once.

NYC used to have brooks, and creeks all through #BROOKlyn and the #Bronx and #Manhattan. Clear bubbling brooks rolled over the foundations of today’s skyscrapers.
Engineers put the streams in underground drain tunnels but gravity returns water to old paths

How #Reflective #Paint Brings Down #Scorching #City #Temperatures. Cities across the U.S. have found relief from this summer’s record-setting heat with the help of technologies that shield #roofs, #pavement and other surfaces from the sun’s scorching rays. Some of these technologies have been around for more than a decade but are experiencing greater demand as global temperatures rise. https://www.msn.com/en-us/weather/other/technologies-help-cities-and-neighborhoods-beat-the-heat/ar-AA1ggJSx #heat #climatecrisis #ReflectiveCoating #paint #GreenRoofs #temperature
