2 Consider:

  • Context:
    • Zero Carbon Hub published information on overheating and reported 20% of housing overheats already.
    • Southern and Western rooms suffered most, attic and upper floors suffer more than intermediate or lower floors.
    • It is reported that 90% of housing will be overheating by mid 2030’s
    • Zero Carbon Hub understood that solar gains through windows needs to be addressed.
    • Zero Carbon Hub failed to understand solar gains through lightweight opaque building fabric (walls and roofs) also needs to be addressed.
    • Heavyweight wall construction using masonry, concrete, Cob, CobBauge, Rammed Earth, Hemp-lime, etc. offer substantial protection from solar heat gains,
    • Lightweight wall construction using light timber frame, light steel frame with glass or stone wool or plastic insulation offers little or no solar overheating protection.
    • Lightweight roof construction including timber frame, metal frame with clay, stone or concrete roof tiles do not offer protection from solar heat gains.
    • Lightweight wall construction using brick slips does not offer solar heat gain protection.
    • Rainscreen cladding could offer some protection but needs lots of ventilation of the air space behind.
    • Building Integrated PV panels offer no solar protection since the heat in the PV reradiates heat inwards.
    • PV on framing above the roof surface offers some solar protection if wind is dispersing the heat from their underside.
    • Warehouse buildings usually use wrinkly tin roofs and wall cladding with stone wool insulation to control fire spread, they will solar hear gain overheat easily and cold food storage uses energy intensive air conditioning to stay cool.
    • We need to consider solar shading above roofs, rooflights, roof windows, outside of lightweight construction.
    • External Solar Shading is a passive method of keeping buildings cool in summer.
    • External Solar shading on glass facades is probably essential:
      • But probably also creates thermal bridges through that façade.
    • Solar protective coatings on glass are the poor man’s answer to solar shading:
      • But probably is not cheap.
      • Is better than nothing.
    • Solar shading can also be about controlling reflection from a façade:
      • Especially curved surfaces that concentrate reflected light
      • Rafael Vinoley’s ‘Walkie Scorchie’ tower melted stuff on the opposite side of road.
    • Avoid: Steel, Aluminium, Plastics (all high % of man-made CO2)
    • Frippery which plays no useful function in terms of solar heat gain control
    • Don’t continue east, south and west solar shading around the northern façade, or you are wasting resources and probably creating thermal bridges in the worst location.
      • Comments apply to Northern Hemisphere
      • Northern Hemisphere North facades do not need solar heat gain shading,
        • But you might want to control other issues.
        • Exclusion of UV light, using PVB interlayer in laminated glass.
      • PHPP Passivhaus principles:
        • Limit quantity and size of windows on east and west elevations to reduce potential for solar heat gains.
        • Permit larger windows on south elevation but add solar shading.
      • Solar shading that shades in summer and permits passage of light in winter.
      • Insulated moveable close able blinds that add to the U-Value envelop.
      • Recycling of Coated Aluminium: See Z3
      • Recycled content aluminium: See Z11.2
      • Plastics: Sawing plastics, as the swarf is rarely collected and prevented from entering watercourses and adding to the micro-plastics in the oceans and sea-life.

24 Sustainable Development Goals

  • The Sustainable Development Goals (SDGs), also known as the Global Goals, were adopted by the United Nations in 2015 as a universal call to action to end poverty, protect the planet, and ensure that by 2030 all people enjoy peace and prosperity.
  • The 17 SDGs are integrated—they recognize that action in one area will affect outcomes in others, and that development must balance social, economic and environmental sustainability.
  • Countries have committed to prioritize progress for those who’re furthest behind. The SDGs are designed to end poverty, hunger, AIDS, and discrimination against women and girls.
  • The creativity, knowhow, technology and financial resources from all of society is necessary to achieve the SDGs in every context.
