HVAC RENOVATION

描述（由申请人提供）：该项目的总体目标是为乔治敦大学比较医学部（DCM）的主要翼楼提供HVAC翻新。该机构有短期和长期目标，以改善和支持动物设施的基础设施。25，000平方米英尺34个基础和临床应用研究实验室使用实验动物，研究领域包括乳腺癌、前列腺癌、宫颈癌和膀胱癌;糖尿病;血管生成;信号传导;激素调节;传染病发病机制;以及神经系统疾病和损伤。 Brown Wing HVAC系统的组件的老化和状况导致需要更换现有的排气扇，加湿器，定容箱和楼宇自动化系统（BAS）。现有的加湿器和定容控制箱是半功能的和/或不可操作的。使用20年的直驱式排气扇仅在82%的设计容量下运行，在电机故障的情况下更换风扇将是困难的。原来的建筑管理系统已经过时，不符合大学范围内的控制标准。 大学将购买和安装大楼管理系统。这笔赠款将购买两个皮带驱动的排气扇，七个区域加湿器和七个定容箱，并支持所需的装修，以安装在布朗翼上方的机械间隙空间这种设备。新的HVAC设备对于保持适当的空气平衡能力，在动物房中提供适当的温度/湿度水平以及提高排气能力，冗余和服务至关重要。此次改造将保护动物健康，控制研究环境条件，并保持机构符合实验动物使用管理指南（指南）中的建议，美国实验动物管理评估和认证协会（AAALAC，国际）的认证标准和美国农业部（USDA）法规。

DESCRIPTION (provided by applicant): The general objective of this project is to provide HVAC renovations for a major wing of the Division of Comparative Medicine (DCM) at Georgetown University. The institution has both short term and long term goals to improve and support the animal facility infrastructure. The 25,000 sq. ft. wing (Brown Wing) houses laboratory animals used by 34 basic and clinically applied research laboratories who conduct studies in breast, prostate, cervical and bladder cancer; diabetes; angiogenesis; signaling; hormonal regulation; infectious disease pathogenesis; and neurological disorders and injury. The age and condition of components of the Brown Wing HVAC system drive the need for replacement of the existing exhaust fans, humidifiers, constant volume boxes and the building automation system (BAS). The existing humidifiers and constant volume control boxes are semi-functional and/or inoperable. The 20 year old direct drive exhaust fans are only functioning at 82% design capacity and fan replacement would be difficult in case of motor failure. The original building management system is antiquated, and does not meet University-wide control standards. The University will purchase and install the building management system. The grant will purchase two belt driven exhaust fans, seven zone humidifiers and seven constant volume boxes and support the required renovations to install this equipment in the mechanical interstitial space above the Brown Wing. New HVAC equipment is essential to maintain proper air balancing capability, provide appropriate temperature/humidity levels in animal rooms and improve exhaust capacity, redundancy and servicing. This renovation will safeguard animal health, control research environmental conditions and maintain institutional compliance with recommendations in the Guide for the Care of Use of Laboratory Animals (Guide), the accreditation standards of the American Association for the Assessment and Accreditation of Laboratory Animal Care (AAALAC, International) and the United States Department of Agriculture (USDA) regulations.
