The modern healthcare management team must accept the challenge of new facility design that allows medical professionals to deliver quality care and allows a process of continuous improvement for our healthcare systems. The various flows of patients, professionals, staff, and visitors, materials, into and out of a healthcare facility is the major driver of all decisions the team evaluates during the facility design process. Analysis of all of the flows of the current facility offered insight and specific design changes that greatly enhanced the new facility design. Objective identification, measurement and understanding of current performance factors that will impact the design of the new healthcare facility can be provided by an experienced IE working with other members of the design team. Understanding perceptions and performance, getting medical professionals appropriately involved, drive team input through performance measurement and data, simple design, timely team education, and design for flexibility are some of the factors that must be considered while designing a medical facility.

The major- and area-source boiler rules are here to stay. There is no one-size-fits-all compliance option. Facility owners need to review their options carefully and develop a strategy that best fits their unique situations while taking into consideration many factors, including capital expenditures, operating costs, and the likelihood of more stringent environmental regulations in the future.

VAV reheat systems once were convenient and made good economic sense for use with high air-change rates. Today, stretching VAV designs to address the competing motives of good ventilation and energy savings can be complex and expensive. By combining a DOAS with an inherently efficient heating and cooling system, such as VRF, a system designer can find system efficiencies that go far beyond those commonly achieved with VAV with terminal heat. Designers would be well-served to break through to the new DOAS paradigm and consider supplementing their DOAS with VRF. Such systems take advantage of VRF's inherent energy recovery, better controllability, ease of design coordination, and reduced space requirements. In addition to simplifying system design and operation, the use of DOAS/VRF, in lieu of old-style VAV reheat, provides "greener" systems by reducing both energy use and overall life-cycle cost.

The comprehensive planning of a float glass furnace cold repair project minimizes the risk of problems during start-up and optimizes the downtime. The effective planning requires an effective safety plan that involves defining critical work areas and safety zones and communicates it to all necessary plant and contractor staff in advance of any construction activity. Signs indicating safety zones should be posted prior to pre-shutdown activities, which is also the appropriate time to begin holding project safety meetings. The safety plan should identify all electrical, air, natural gas, and other process and utility feeds in areas scheduled for demolition or other work. Other components of the planning are proper scheduling, staging areas that should be assigned to each contractor and efficient procurement and inventory, which involves identifying materials with long lead times and those that may be difficult to obtain. The project team should check out electrical panels to the farthest extent possible at the panel shop before shipping.

Experts from the industry suggest that understanding building information modeling (BIM) software as an operation and management (O&M) tool can help businesses in dealing with the challenge of increasing prices. BIM software provides an in-depth visual model of project elements, such as demolition, construction, renovation and operations maintenance, when used as an O&M tool. It also connects the visual model to scheduled time durations and sequence of implementation values, enabling more efficient management of all tasks. Savings arise from lowered construction costs for materials, equipment and labor, while freeing every member of the team to more easily envision the work to be carried out. Additional time and cost savings also result when BIM software is integrated with two key software applications used by federal contracting agencies.

Laboratory owners can commission infrastructure upgrades and new, energy-efficient systems fitted to new engineering standards. These laboratory renovations require an energy master plan, a supportive budget and an intelligently-phased approach to construction. The first step in developing a master plan is to construct a model of how the facility uses energy, how much energy the facility uses, and how much it costs. The energy model will reveal where more energy is being used than necessary and suggest a number of more efficient options. An analysis of the options will produce a cost estimate for each as well as a payback period based on the energy that the renovation will potentially save. Energy-modeling software has been used by the Environmental Protection Agency (EPA) for an existing facility to model energy use across a six-building laboratory campus.

Modern simulation software running on a desktop computer makes it possible to automate process and create higher performance for the chemical process industries (CPI). With distillation column design, simulation software can help maintain expensive components within the overall project's budget limits. The software enables the engineer to work with the program features to ensure that a distillation column will be no taller than the process requires. Simulation software can also help to develop production routines, such as establishing the optimum order in which each raw material should be processed to produce the timeliest result. Simulation can help a processor minimize the amount of work involved with controlling inventories and the flow of materials. This keeps complex material flows from overwhelming the process and causing errors. Simulation software analyzes costs of materials and transport, cleaning of drums and disposal. A number of simulation software applications are available on the market.

Some of the steps needed to set up an effective greenhouse gas monitoring plan are discussed. An important element of the program is developing and implementing a reliable written monitoring plan that describes how the facility will comply with the requirements. Setting up a successful monitoring plan involves a few important steps, including identifying sources of GHGs; determining the proper methods for monitoring; collecting the data; and selecting the procedures and methods for calculating and quality-checking the data from each measurement device or method. A site also must evaluate the GHG Rule's industry- sector-specific emission sources, if applicable, for inclusion or exclusion from the list of identified sources. A site may develop measuring strategies based on the source and source categories listed in the rule subparts. The monitoring plan must outline data collection, calculation and data maintenance procedures. The plan should outline where data from each source is to be stored and maintained.

Several factors that need to be considered when choosing the pinch analysis are presented. The minimum thermodynamic requirements for hot and cold utilities can be calculated for a process when using this method. A temperature-enthalpy diagram (T-H diagram) is used to plot the hot and cold streams from the process and the temperatures where they are available. The grand composite curve is created by subtracting the hot curve duties from the cold curve duties at each temperature. Where there is no cold line to subtract the hot duty from, use the duty at the end point of the cold curve. The utility temperatures give the shifted temperature of the utility required to achieve the desired process-outlet temperature. The actual temperature required would be the shifted temperature plus one half of the pinch temperature for the hot utility, and minus one half of the pinch temperature for the cold utility. Utility at 65°F is usually much cheaper to obtain than one at 4°F that requires a refrigeration system.
