A mathematical model was developed and used to study the effect of various energy conservation measures
to arrive at a set of design features for an energy efficient greenhouse. The Simulation results indicated
that under cold climatic conditions of northern India, a gothic arch shaped greenhouse required 2.6% and
4.2% less heating as compared to gable and quonset shapes. An east–west oriented gothic arch greenhouse
required 2% less heating as compared to a north–south oriented one. North wall insulation of an east west
oriented gothic arch greenhouse saved 30% in heating costs. The use of night curtains reduced the night
time heating requirement by 70.8% and daily requirement by 60.6%. By replacing the single cover on the
southern side with air inflated double wall glazing, the heating requirement was reduced by 23%. The
combination of the design features for an energy efficient greenhouse suitable for cold climatic conditions
was found to reduce the greenhouse heating needs by 80%. An internal rock bed thermal storage/retrieval
system met the remaining heating energy requirements of the energy-conserving greenhouse.
