The present invention relates to a greenhouse facilitating warming, sunlight control, and ventilation, wherein according to the present invention, the ventilation, warming, and light shielding can be effectively performed inside the greenhouse, and in case of rain, the greenhouse can be ventilated while preventing rainwater from flowing into the greenhouse. The greenhouse has a constitution in which openable and closable side windows (150) are respectively formed on both sides of a lower portion of a tunnel type greenhouse (100). First side greenhouse frameworks (110) from one ground to a center portion of an upper part of the greenhouse and second side greenhouse frameworks (120) from the other ground to the center portion of the upper part of the greenhouse are installed at an equidistant interval along a length direction of the green house. A transparent film is installed to cover the first side greenhouse frameworks and the second side greenhouse frameworks installed at the equidistant interval. The tips of central portions of upper parts of the first side greenhouse frameworks (110) are formed to be higher than the tips of central portions of upper parts of the second side greenhouse frameworks (120), so that a space (130) is prepared between the upper parts of the first side greenhouse frameworks and the upper parts of the second side greenhouse frameworks, and an upper opening and closing window (140) is installed for the space. Pillars for supporting the tips of the first side greenhouse frameworks and the second side greenhouse frameworks are installed at an equidistant interval along the length direction of the greenhouse.COPYRIGHT KIPO 2014본 발명은 온실 내부의 환기와 보온 및 차광을 효과적으로 할 수 있음은 물론, 우천시에도 빗물이 온실 내부로 유입되지 않으면서 환기시킬 수 있도록 한 보온 및 일조량 조절과 환기가 용이한 온실에 관한 것으로, 그 구성은, 각종 식물이 재배되는 터널형 온실(100)의 하부 양 측면에 개폐가능한 각각의 측면개폐 창(150)을 형성시켜 된 온실에 있어서, 상기 온실은 일측 지면에서 상측 중앙부에 이르는 일측온실골조(110)와 타측 지면에서 상측 중앙부에 이르는 타측온실골조(120)를 온실의 길이방향을 따라 등 간격으로 설치하고, 그 등 간격으로 설치된 일측 및 타측온실골조의
