  • 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?






  • Yeah, it might be a good idea to check if the downspout isn’t partially clogged. I don’t know how high that building is, but around here, leaves can get in there every once in a while

    If you haven’t checked yet, you might also want to see the abutment flashing (see #7 below) where that wall and roof meet, as water might be percolating in that area and getting trapped between the ceiling/drywall/insulation.

    I’d also check the other flashings as well while you are at it and if that drywall and insulation on that affected area are damp, remove them for venting

    I can’t tell too much from the pictures, nor feel and test the wood. You mentioned the plaster was soft, but what about the wood? Are there mycelium growth in it?

    Check if the wood is dark, mushy, deformed, poke test it with a knife/awl/screwdriver, as wood with advanced decay will be soft and the probe will penetrate easily. How far does it go? How big is the beam? Do you know what kind of wood is it? Test in multiple areas

    Tear up a more of the plaster to check how the rest of the beam looks like and test them. If it is less than 0.3 cm, venting might be enough

    Another one is the pick test, where you insert the knife beneath the wood grain to pry loose a thin section of it till it breaks free. If you get a long linear splinter, itś most likely good, if it comes out as crumbly chunks or short pieces with a mushy sound, it is not ideal.

    If you are in a dry season and no rain in sight, I’d clean both inside and outside areas to let them vent. Get a fan/dehumidifier/open windows in that room.

    I also prefer breathable buildings, so you could use a more traditional breathable plaster, which allows water to easily evaporate over time, whereas concrete and all the PVA might help trap the moisture. It is typically made from lime and/or clay, sand, and water. You can also add fibers (horse hair or plant fibers) for strength



  • I’m no specialist, but I’ll give my two cents. Anyone feel free to correct me if I’m wrong or a better approach is available

    1. Yes, even galvanized steel will eventually rust when directly in contact with the ground and it was accelerated by the salty air from the coastal region. It also rusts faster in high humidity air/soil. Even after sealing the roof, it will rust again from capillary humidity from the soil if laid directly against it

    2. Concrete or rock footing around 10-20cm above ground level is what I usually see, make sure the water drains and it isn’t pooling between footing and post. Those stirrups are usually galvanized steel, but if your post is already galvanized steel, I guess it wouldn’t make sense in your case

    3. Based on the first image, if you were to use a concrete footing above ground, you might even be able to salvage this post, as the two screw holes look unrusted on the picture, and they seem to be around the level you’d need to cut. You might need to grind down the area and look on the inside to confirm it. If it is, you won’t even need new brackets

    Otherwise, yes, a local shop will probably have some 90° brackets and bolts too. Keep in mind to accommodate the requirements for hurricane/flood/frost if your region is prone to it



  • 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




  • Unfortunately they usually do it on farmland around here, when they could easily go the agrivoltaics route. They would only need to raise it a meter or two and let the sheep roam around doing the trimming for them

    Depending on location, it would have been cheaper to have those posts raised/reinforced in the first place instead of buying and hauling all that gravel
