“…Çeker ocaklar laboratuvarlarda en fazla gerekinim duyulan ekipmanlardır. Çeker ocak olan binaların enerji tüketimi tipik ticari binalara göre 4-5 kat daha fazladır [13]. Farklı hava hacimlerine ve farklı pozisyonlara ayarlanabilir Çeker ocak veya davlumbazlar enerji maliyetini düşürecektir [14].…”

“…Farklı hava hacimlerine ve farklı pozisyonlara ayarlanabilir Çeker ocak veya davlumbazlar enerji maliyetini düşürecektir [14]. Berkeley tipi davlumbazlarda kullanılan özel bir başlık ile kullanıcının ön tarafı temiz hava beslenir, bu başlık ile kimyasal buhar ve kirletici gazlar yalnızca% 20-40 oranında çekilerek hem enerji maliyetleri azaltılır hem de kullanıcının önünde kirletici olmayan ortam sağlar [13].Davlumbazlar, güvenlik endişeleri nedeniyle kullanımları arasında kapatılmadığında enerji tasarruf modunda çalışması sağlanmalıdır. Ancak yeni üretilen davlumbazlarda metaloksitdedektörleri, gaz doygunluk ve asit uyarı göstergeleri ile güvenlik endişeleri azaltılmıştır [15].…”

ÖZÇevre laboratuvarları rutin kullanımlarında basit solvent, su veya özel bertaraf gerektiren biyolojik veya kimyasal tehlikeli atıklar gibi çok çeşitli ve çok miktarlarda atık üretmektedir. Yeşil Laboratuvar sertifikası, laboratuvarın sürdürülebilirliğini arttırmak için ilkeler belirleyen bir sertifikasyon yöntemidir. Yeşil laboratuvar sertifikasının sadece kuruluş veya firmalar değil, ülke ve bölgeler içinde önemli risk yöntemi ve rekabet avantajları sağladığı bilinmektedir. Bu çalışma da Türkiye'deki çevre laboratuvarlarının çevresel sürdürülebilirliği 31 yeşil laboratuvar ilkesine göre anket tekniği kullanılarak değerlendirilmiştir. ABSTRACTEnvironmental laboratories create a lot amount of waste in the routine use; waste products range from simple solvents, such as water, to biologically or chemically hazardous wastes that require special disposal. The Green Laboratory certificate is a certification method that determines principles to increase the sustainability of the laboratory. It is known that green laboratory certification provide significant risk methods and competitive advantages within countries and regions, not just individual organizations or companies. In this study, the environmental sustainability of environmental laboratories in Turkey was evaluated according to the 31 principles of green laboratory using survey techniques.

“…Fume hoods are commonly installed in R&D laboratory facilities in the pharmaceutical industry. Fume hoods capture, contain, and exhaust hazardous gases generated by laboratory activities and industrial process and therefore protect workers from breathing harmful substances (Mills and Sartor 2004). The energy required to heat and cool make-up air for laboratory fume hoods can account for a significant fraction of laboratory HVAC energy consumption.…”

“…A reduced volumetric flow requirement can facilitate lower energy consumption in variable flow hoods. A fume hood's sash opening can be limited either by restricting the vertical sash movement or by using a horizontal sash to block the hood's entrance (Mills and Sartor 2004). Furthermore, sashes on unattended fume hoods should remain closed whenever possible.…”

“…Variable-air-volume hoods, which employ ASDs and direct digital control systems to adjust exhaust airflow based on face velocity requirements, can offer considerable energy savings compared to CAV hoods. Variable-air-volume hoods save energy by minimizing the volumetric flow rate of hood exhaust, which can lead to significant reductions in the amount of exhaust air that must be conditioned by a building's HVAC system (Mills and Sartor 2004). The Louis Stokes Laboratories of the U.S. National Institutes of Health recently installed VAV hoods and experienced savings in energy consumption of up to 70% compared with conventional CAV hoods (U.S. EPA/ DOE 2001b).…”

The U.S. pharmaceutical industry consumes almost $1 billion in energy annually. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There are a variety of opportunities available at individual plants in the U.S. pharmaceutical industry to reduce energy consumption in a cost-effective manner. This Energy Guide discusses energy efficiency practices and energy efficient technologies that can be implemented at the component, process, system, and organizational levels. A discussion of the trends, structure, and energy consumption characteristics of the U.S. pharmaceutical industry is provided along with a description of the major process steps in the pharmaceutical manufacturing process. Expected savings in energy and energy-related costs are given for many energy efficiency measures, based on case study data from real-world applications in pharmaceutical and related facilities worldwide. Typical measure payback periods and references to further information in the technical literature are also provided, when available. The information in this Energy Guide is intended to help energy and plant managers reduce energy consumption in a cost-effective manner while meeting regulatory requirements and maintaining the quality of products manufactured. At individual plants, further research on the economics of the measures-as well as their applicability to different production practices-is needed to assess potential implementation of selected technologies.iv This Energy Guide first describes the trends, structure, and production characteristics of the U.S. pharmaceutical industry. Next, a description of the main production processes and a discussion of energy use in the pharmaceutical industry, including the main end uses of energy, are provided. Due to the wide variety of products and production methods in the U.S. pharmaceutical industry, it is impossible to describe all energy end uses. Therefore, this Energy Guide focuses on the most important end uses of energy in typical U.S. pharmaceutical plants. Finally, the remainder of this Energy Guide discusses opportunities for energy efficiency improvement in U.S. pharmaceutical plants, focusing on energy efficient measures and technologies that have successfully been demonstrated in individual plants in the United States or abroad. Although new energy efficient technologies are developed continuously (see for example Martin et al. 2000), this Energy Guide focuses on those technologies and practices that are both proven and currently commercially available.
