Passive Measures:
  • Passive solar design
  • Rainwater harvesting and recycling
  • The units have been constructed with pre-fabricated solid cross (FSC) timber, from a sustainable source with external insulation.
Renewable Technologies Employed:
  • Low energy LED lighting
  • PV Panels.
  • Biomass pellet boiler
  • Mechanical Ventilation with Heat Recovery (MVHR) incorporated with a heater coil for space heating and weather compensated control
  • Low energy white goods
  • Green roof
  • Low flow rate sanitary ware
  • Rooflights are triple glazed with seals against weather and draught. The windows are also triple glazed.
  • External doors are fully insulated
  • High levels of insulation have been implemented with low air-permeability
Challenges Encountered:
Space was limited and so became a difficulty with regards to installing the renewable technologies. Problems were also encountered concerning conflicts of interest such as requirements for wheelchair access on spatially constrained sites.
