PROBLEM TO BE SOLVED: To provide an inexpensive energy-saving cultivation facility higher in energy-saving effect than conventional ones.SOLUTION: To solve the problem, the invention provides an energy-saving cultivation facility, including a fuel combustion type first heating apparatus for heating air inside the facility and for discharging exhaust air to the outside, which comprises a second heating apparatus for heating air outside the cultivation facility and for blowing the air as warm air into the cultivation facility. In the energy-saving cultivation facility, a quantity of warm air blown by the second heating apparatus into the energy-saving cultivation facility is equal to or more than a quantity of air inside the facility to be discharged to the outside by the first heating apparatus, e.g., 1.3 times or higher, so that the inside of the energy-saving cultivation facility is maintained in positive pressure.【課題】従来よりも省エネ効果の高い、廉価な省エネ栽培施設を提供する。【解決手段】本発明は、上記の課題を解決するために、施設内部の空気を暖め外部に排気を排出する燃料燃焼式の第一暖房装置を備える栽培施設において、前記栽培施設の外部の空気を暖め前記栽培施設内に温風として送風する第二暖房装置を備えることを特徴とする省エネ栽培施設、また前記第二暖房装置による前記省エネ栽培施設内への温風の送風量が、前記第一暖房装置によって外部に排出される施設内部の空気量以上、例えば、１．３倍以上とし、前記省エネ栽培施設内を陽圧とすることを特徴とする省エネ栽培施設の構成とした。【選択図】図１
