  • I’d like to push back a little on your second paragraph, as most of the listed things mentioned can be remediated with appropriate planning/actions. Of course every case is a different one, this always depends on the local context, but as a general rule:

    Trees are expensive to maintain

    If you plant native trees, that usually isn’t a big problem, as they have been adapting themselves to those conditions for thousands of years

    in addition to cracking sidewalks and roads

    You can always select appropriate trees species that don’t have such aggressive root system that tends to crack them

    they need water

    Once again, native trees are your best bet, in conjunction with water harvesting techniques, I don’t think it will be a problem. I always recommend Brand Lancaster and Andrew Millison work on this subject. See Harvesting Rain Water for more details

    If you prefer video format:
    “Free water was illegal… He changed that…” [19m15s]

    the leaves need to be cleaned up

    I always find this a weird obsession, why do we have to clean them up? In a forest, it usually lies on the floor and becomes nutrients, habitat, reduces water evaporation from the soil, protects the soil from erosion, etc

    they need to be trimmed

    This one depends a lot on the context, but at least around here, trimming usually means butchering trees and making them completely unbalanced, which makes the population even more upset as your point below becomes the likely scenario

    they pose a liability risk so need to be covered by insurance

    Healthy trees are not likely to cause problems. Again this one depends on how the city deals with it, but routine check ups should be more common

    Considering all the benefits greenery has in our lives, I still think we come out way ahead with it in the long term, even if we were only looking at it from an economic perspective



  • I’ve seen green roofs on bus stops and favelas in Rio, Brazil, where their roofs have terrible infrastructure. From what I understood, they basically partnered with a local university to try to reduce the heat island effect in favelas, as most of them had no greenery at all

    They came up with a cheap solution involving a plastic liner, similar (perhaps the same) to those used in ponds; a geotextile layer of bidim, which is a lightweight material; and plants that don’t need soil to grow, like those found growing on rocks or trunk of trees. Which means it is super light and still provide the same benefits as a green roof with soil in it














  • Why do our hospitals look so bleak? We could have greener hospitals like Khoo Teck Puat or Ng Teng Fong, both in Singapore

    Khoo Teck Puat hospital as an example:

    Designed to be ‘forest-like’, water features with aquatic species, and plants that attract birds and butterflies were introduced. Greenery extended from the central courtyard to upper levels of the buildings and down into the open-to-sky basement, creating the impression of architecture deeply enmeshed in a garden. At the upper levels, balconies with scented plants bring the experience to the patient’s bedside.

    Total surface area of horizontal and vertical greenery is almost four times the size of the land that the hospital sits on. In addition, 18% of the hospital’s floor area account for blue-green spaces and 40% of all such spaces are publicly accessible

    […] Common areas such as the main lobby and public corridors were specially designed for optimal natural ventilation thereby reducing the need for mechanical ventilation and energy consumption. By orientating the subsidized ward tower to ‘capture’ the prevailing North and South East winds, an optimal wind speed is achieved which would provide adequate thermal comfort for the patients.

    […] It is also a serves as a tranquil communal node where the local community can attend public lectures, exhibitions or participate in educational programs organized by the hospital.²

    The energy-efficient design reduces energy costs by 50% and provides 40% of the floor area with the potential for natural ventilation.³

    Video format about it for those that prefer it:

    You probably won’t be able to redesign/retrofit everything, but perhaps just a little bit more green instead of only concrete?




  • how it handles the load exceeding capacity

    As in what happens if you plug too much stuff that it exceeds your solar production?

    I’ll use mine as an example, but it might be different with different models and configurations:

    Inverter can handle up to 10kw
    If solar production is at 5kw, and home is demanding 7kw, in my case, I have it set up as to draw the remaining 2kw from the battery, if battery is depleted, it will draw 2kw from the utility company

    If home demands more than 10kw that the inverter can handle, it will trip the internal inverter protection or a circuit breaker leading to it
