GBE > Encyclopaedia > Code > Brain Dump  G#42497

About:

Vacuum Glazing:

  • Vacuum glazing has had a role in historic buildings for sometime
  • Providing a thin solution for replacing single glazing with a thin double glazed sealed unit
  • Able to be fitted into exiting glazing frames and beads with little or no modification
  • There is a new role for vacuum glazing as high performance glazing that can be used in any new or any existing building
  • Primarily as an energy saving measure with significant better U values
    • Impending regulations will see a far greater demand for thicker glazing including triple glazed sealed units requiring larger section frames to accommodate them
    • or vacuum glazing in smaller sections
  • Additional properties offered by vacuum glazing include:
    • Thermal comfort: by increasing the internal temperature of the glazing towards the temperature of the internal face of the external wall; discouraging occupants reaching for the thermostat
    • Acoustics: allowing the occupants to concentrate on their tasks avoiding external noise penetration
  • Refurbishment of existing buildings will find vacuum glazing has a significant contribution to energy saving and may become an essential part of many if not all projects.
  • In the case where adding thermal insulation is not permitted by Conservation Officers, vacuum glazing allows an uncomplicated improvement without forcing the need for expensive ventilation
    • Publicly Available Standard PAS 2030 slogan: No insulation without ventilation

Homemakers Issues:

  • Costs of heating
  • Fuel poverty for millions, on top of food poverty, furniture poverty, etc.
  • Rising energy bills making heating unaffordable
  • Ability to continue to pay bills and desire for long term continuity of tenancy
  • Thermal comfort need for warm draught free homes, especially the aged
  • Acoustic intrusion reduction improving wellbeing and avoiding stress for animals and Post Traumatic Stress Disorder PTSD sufferers, from airports, roads and fireworks
  • Avoiding condensations & mould, asthma, toxic mound, death
  • Unintended consequences including avoiding summer overheating
  • Avoiding unnecessary or redundant upgrades
  • Improvement opportunity
  • Inconvenience of intervention installation
  • Security and protection of home and possessions during works
  • Aftermath of interventions, getting life back in order simpler after reglazing

Housing Provider’s Homemaker issues:

  • Addressing Homemakers’ issues
  • Long term tenancy continuity: Ability to pay bills
  • Getting tenants out of fuel poverty by many means possible
  • Thousands of Homes and Homemakers to rally around to accept changes with minimal interruption
  • Avoiding decanting homemakers during works, avoiding tenant disruption
  • Avoiding cooling down thermally massive building fabric whilst windows are removed and replaced
  • Security of homemaker’s possessions, 24 hour security
  • Avoiding decanting possessions and reinstating on completion
  • Wanting confidence that interventions will make a difference to bills

Landlords and Housing Provider’s Bigger issues

  • Follow up on Climate and Biodiversity Emergency Declaration
  • Urgency of climate interventions timeline
  • Lowering energy usage
    • Efficiency improvement
  • Carbon obligations:
    • Embodied Carbon (materials and waste)
    • In use Carbon (Energy and its carbon load)
    • Reducing footprint by limiting waste and transportation
  • Scope 1 2 & 3 impacts
  • Meeting PAS 2030 and 2035 obligations with existing older and pre-1919 housing stock
  • Concentrate on window, doors and rooflights
  • Protection of exposed building Fabric
  • Historic building protection and conservation officer’s challenges
  • No one intervention preventing another, no duplication of effort, no redundancy, no waste
  • Determining appropriate interventions for all eras of construction method
  • Avoiding unintended consequences (see Sustainable Traditional Buildings Alliance (STBA) Guidance wheel image)
  • Budgets for contracts paid for by savings on bills
  • Long life interventions: vacuum glass with 15 year guarantee and 25-30 years life expectancy
  • Budget constraints: Need for cost effective, high impact, interventions
  • Looking for return in investment, best value, value for money
  • Fast turnaround, Rapid returns

Heat losses

  • BRE show standard % of heat loss from elements of buildings
  • House energy pie charts are not an accurate guide, and different with each era of construction
  • Based on which era of construction, method of construction, date of regulations, window specification, insulation and U values?
  • They are rarely applicable to your building, relevant nor accurate
  • Worse case scenario: highly insulated walls, floors, roofs and existing retained single glazed windows
    • 5% of envelop spews out 50% of energy through the windows
    • Some properties have vast windows: 50%-100% glazed
  • And the ‘performance gap’ suggest we rarely get what we pay for
  • Every homemaker has their own pie chart of behaviour to overlay on the house energy consumption pie chart
  • We need calculators that can provide accurate data related to any building

Decision making data at your fingertips

  • Fabric first & whole house approach (especially with Air Source Heat Pumps ASHP)
    • U values of 0.49 W/m2.K
  • In addition to insulation, windows are the most important places to spend money
  • The windows, doors and rooflights
  • With the right information at your fingertips, clients can make the best well-informed decisions
    • In use energy and carbon,
    • embodied energy and carbon
    • initial cost and long-term cost savings,
  • All calculations in one place and at the same time
  • Furthermore if done well any change in a specification should provide instantaneous comparisons
  • Green Building Calculators (GBC)
    • Can do all these things
    • Has summary sheets that show 5% of the envelope can be spewing out 50% of the energy
    • Value engineer, do not cost cut
    • Totex = Capex + Opex
    • Whole Life carbon = Embodied Carbon + In use Carbon
    • Whole life Cost = Intervention Cost + Running cost
  • Slide

Window glazing details and issues:

  • Window materials
  • Single Glazing
  • Glazing materials, historic to be retained and reused?
  • Secondary Glazing
  • Double Glazing: not practical to reuse historic glasses?
  • Cavity gasses: Expensive, do they leak over time, with diminished performance?
    • Glass & Glazing Federation GGF are investigating
  • Low E (Low Emissivity) coatings: important to reflect radiant heating sources and outward heat flow
  • Warm edge spacers reduce thermal bridging at glass perimeter
    • (Especially important in metal frames)
  • Acoustic glazing options: fireworks, avoid scaring pets and PTSD sufferers
  • UKAS accredited test Rw 36 dB
  • Triple Glazing for thermal comfort to Passivhaus standard, avoids occupiers reaching for the thermostat
  • Vacuum Glazing options: energy saving, thermal comfort and quiet
  • Thermal comfort:
    • single and double glazing internal temperature gives perception of cold drafts
    • triple glazing 17 degrees internal temperature close enough to wall temperature
      • to not feel cold and not reach for the room thermostat
      • or with Vacuum Glazing an ultra-thin profile of 6.15 to 28 mm
    • Safety glass, impact performance and containment
      • Below 800 mm above floor
      • In doors and surrounding glazed screen
      • Stair balustrades
      • Balconies
      • Shower screens and enclosures
      • Upper floor windows, glass walls
    • Beading:
      • Internal: no scaffolding
      • Internal: accessible casement face ironmongery: No scaffolding
      • External: scaffolding needed,
        • Mobile scaffolding no longer permitted?
        • MEWPs Mobile Elevating Work Platforms and VPLs Vertical Passenger Lift?
      • Obscured glazing for bathrooms: textured surface, compatibility with perimeter sealant
        • Texture inwards, into cavity? Sufficient space?

      • Clustered works can lead to scaffolding cost savings,
        • moving from building to building,
        • not sending back to base not starting from base each time

Wasted Resources

  • Removal of windows, casements or sashes, removal to logistic centre:
    • dismantle, segregate for recycling or disposal
  • Removal of replaced casement or sash to workshops to upgrade glazing for next replacement
  • Manual handling and removal from scaffolding to skips and pallets or crates
  • Ignores Global, EU and UK Circular Economy ambitions
  • Large work force needed, with a respectable level of skills training
    • PRIME Horizon Europe project Waste minimisation and Migrant Workforce
      • University of Bristol are partners
    • Non-westernised folk tend to have a different perception of resourcefulness
    • Segregation of waste, reclaim and reuse has not been driven out of them yet
      • In India a bike is a bike is a bike until it rust
      • In the UK a mobile phone is mobile phone until the next model is released
    • Work force of many different nationalities working in the homes of many nationalities
      • Matching nationalities my help to overcome some barriers to rollout.

Replacing windows

  • Survey to determine accurate requirements for manufacture before existing window disposal
  • Long lead times if not made in the UK
  • Complexity of many hundreds of sizes to suit all the houses across the city
  • Sophisticated logistics system to deliver the right sizes to every property
  • Embodied resources, energy and carbon of new windows
    • Especially PVC-U and Aluminium, less if recycled aluminium
  • Pushing window outwards to make larger internal window board for resident’s possessions
  • Bad placement of window can lead to thermal bridges, condensation and mould
    • A Passivhaus certified window in wrong place
    • Can be worse performance than an A rated window in the right place
  • Need to patch repair: internal plaster, external render, weatherboarding, tile hanging
  • Redecoration allowance to homemakers, whole wall > room > house, £500 may not be enough
    • Will it be spent on redecoration? Unlikely?
  • Glass: inert, heavy, recyclable and should be segregated and recycled

Replacing casements or sashes

  • Primarily to avoid multiple panes per window, with inevitable diminished performance
    • partially remove glazing bars,
    • add large vacuum glazed unit,
    • add glued-to-glass artificial partial glazing bars
    • decorated to mimic timber windows
    • challenging to distinguish from real glazing bars and beads
  • Glued on partial glazing bars beads means artificial beads do not fall off into flowerbeds
  • Survey to determine accurate requirements for manufacture or upgrade before existing casement/sash removal or disposal
  • Once process is started extracted consistent sized casement or sashes become feedstock for upgrades to others
  • Made and modified in the UK
  • Upgrade glass, modify beads, redecorate
  • Complexity of many hundreds of sizes to suit all the houses across a city
  • Sophisticated logistics system to deliver the right sizes to every property
  • Significant reduction in embodied resources, energy and carbon over new windows
    • Especially PVC-U and Aluminium, less if recycled aluminium
  • No repositioning of window outwards to make larger internal window board for resident’s possessions
  • No need to patch repair: internal plaster, external render, weatherboarding, tile hanging

    • By home maker or by installer
    • Reposition upon completion
  • Safety hooks for safety harnesses?
  • Remove beads, reclaim for reuse, clean up, reuse, little waste, few new parts
    • Internal or external beads?
      • Secure by Design: should be internal beads, older may be external
    • Access to other side of casement?
  • Remove existing lower performance glazing:
    • single or double glazing to improve U value and thermal comfort
    • or even triple glazing to add vacuum performance
  • Glass: inert, heavy, recyclable and should be segregated and recycled
  • Circular economy: Recycling
    • Glass sand for paving bedding
    • Glass recycled as thermal insulation for the same job
      • (but not for attic insulation, no decrement delay, properties exacerbate overheating)
    • Linear Economy:
    • 28,000 houses x 9 windows = 252,000 windows = 1260 m3 =157 No. 8 cuyd skips (efficiently packed, more if not) and 4 x lorry movements per skip and landfill charges
