2nd generation technical data

Concept

  • Rotatability + concentration of windows on the sunny side = maximum use of solar energy
  • Optimum insulation + air tightness = reduction of heat losses
  • Round layout = smallest possible building shell area = minimisation of heat losses
  • Use of regenerative energies, ecological and sustainable building
  • Rotatability + round layout = protection against heat in the summer and wind

Building

  • Wooden frame construction with passive house construction with external shell and technology
  • 2 2/3 floors + basement, living area = approx. 241m², production area = approx. 54m²
  • Modern architecture, flat roof
  • Metal roofing, zinc steel seam, plaster facade

Rotatability/drive

  • Ball bearing steel rotating assembly, high tensile and pressure-resistant
  • Flanged motor with 0.18 kW, alternatively with 0.0 kW with drive via home trainer
  • Optimised control in hard and software corresponding to position of sun in summer/winter

Energy efficiency

  • Average U value of the external shell = 0.15 W/(m²K)
  • Heating requirements = < 13 kWh/(m²a)
  • Air tightness: n50 = 0.59 (1/h)
  • Passive house windows: Ug = 0.7 W/(m²K), Uw = 0.9 W/(m²K)
  • 4.8 kW heat energy requirement, 6.0 kW cooling requirement

Fittings

  • Solar water heating pump for heating in winter and cooling in summer, deep drilling approx.
    80 m
  • Solar unit for 4 modules vacuum pipe collector for water heating and heating support
  • Buffer store: 2 x 500 l
  • Ventilation unit with heat recovery via cross flow heat exchanger, degree of recovery = 95 %
  • Floor heating system for heating and cooling
  • Photovoltaics unit with 10.5 kWp, yield p.a. = 8,347.5 kWh
