Energy Design and Optimization of a Greenhouse: A Heating, Cooling and Lighting Study

Abstract

This paper presents a new approach to properly optimize the energy consumption in a greenhouse. An improved intermediate modeling to establish the energy balance in a greenhouse within a higher precision was adopted. While the classical model focuses on the efficient cooling and heating demands and neglects the profound impact of lighting parameters, it was shown that these three necessary components are interdependent, and they should be taken into account all together to comfortably reach optimal crop production and energy consumption. This study’s contribution is the classical model’s improvement and the demonstration of the fact that the heat released by the luminaries and the energy used by this equipment has fundamental consequences on the energy balance as well as the preferred choice of the possible shape of the greenhouse and its adequate cover.

Alternative Construction using BIM in Old Educational Buildings

“…The research on the utilization of building energy (Building Energy Efficiency) also defined as greening or modernizing of a building (Building Retrofit), or the process of modifying the structure of the building referring to changes that increase its energy efficiency [17]. One of the most energy demanding sectors in modern agriculture, the greenhouse industry is in definite need of energy consumption reduction [18]. Energy consumption in new commercial buildings may be reduced by 20% -30% on average, and by over 40% for particular building types and locations, with the help of conventional energy efficiency technologies like thermal insulation, low-emissivity windows, window overhangs, and day lighting controls.…”

“…They are not proven to become a green source of electricity. As a result, it can be said that fossil fuels are unsafe, and the accident happens [13] and [2].…”

“…The usage of renewable energy is increased and this will boom the economy of the country [9] and [10]. Many Researchers also proposed to utilize cost-effective and efficient lights [11][12][13]. This will decline energy consumption and save energy expenses.…”

Overview of Green Roof Technology as a Prospective Energy Preservation Technique in Arid Regions

“…As of 2005, Germany had planted 13.5 million m 2 of roof spaces [54,62]. Munich, the Bavarian regional capital (Germany), is implementing a variety of living roof-related initiatives [63]. Such approaches include land use management rules, start-up grants for voluntary living roof construction, and a reduction in storm water levies [64].…”
