EARTH PROTECTION SOCIETY

Wing III · The Society

A single block, accounted for end to end.

Earth Protection Society is not a brand laid over other people's supply chains. It is a charter: what the block consumes, the block accounts for — materials, electrons, buildings and work. Use the menu for the full systems index.

Brief 01

Closed-Loop Urban Metabolism

Every output of one process is booked as the input of another. Waste heat, greywater, organics and scrap steel circulate inside a single metabolic ledger held at the block scale.

  • Shop-floor waste heat recovered into the domestic hot-water loop of the adjacent residences.
  • Greywater polished on site through constructed reed beds, reused for wash bays and tree pits.
  • Organics digested locally; biogas trimmed into the flex-fuel blend used by the range extender.
  • Aluminium and steel offcuts re-melted in the neighbourhood foundry, never leaving the district.

Off-Peak Battery UPS & Load Defection

The campus buys electrons when nobody else wants them. LiFePO4 cabinets charge in the small hours, carry the site through peak pricing, and double as a seamless uninterruptible supply.

  • 1.8 MWh of LiFePO4 across modular cabinets, cycled between 15% and 90% state of charge.
  • Online double-conversion UPS topology: zero-transfer-time protection for the mastering suite.
  • Peak-shaving controller defects up to 74% of billed demand charges away from the utility.
  • Grid-forming inverters allow islanded operation of critical loads for 36 hours.

LEED Platinum Community Standards

Buildings are held to LEED Platinum not as a plaque but as an operating floor — commissioned annually, published openly, and written into every tenancy agreement on the block.

  • Mass-timber and reclaimed-brick structure with a measured 62% reduction in embodied carbon.
  • Triple-glazed envelope, heat-recovery ventilation, no fossil combustion for space conditioning.
  • Daylight autonomy above 75% in all workshop and studio floors.
  • Annual re-commissioning with public dashboards for energy, water and indoor air quality.

Local Technician Job Creation

Sovereignty is a labour question. Drivetrains, batteries and audio hardware are built, serviced and re-manufactured by technicians who live within cycling distance of the shop.

  • Four-year paid apprenticeship covering high-voltage safety, e-axle service and battery diagnostics.
  • Open service manuals and tooling — every vehicle repairable by any certified local shop.
  • Re-manufacturing line keeps end-of-life packs and axles in the local economy.
  • Wage floor pegged to regional housing cost, reviewed publicly each year.
