Garold Hamilton informs about the significance of air filtration in health care facilities. He states that designing air distribution systems to serve hospital environments is a complex undertaking. Selecting the right filtration system plays a key role in preventing the transfer of airborne diseases within the hospital environment. A detailed analysis of the code requirements for air filtration for all health care facilities is provided to address these issues. It will recommend the best engineering practices to ensure compliance with code requirements and means of ensuring that code requirements are properly implemented in the design and selection of AHU systems. There are several guidelines that govern filtration requirements for licensed health care facilities and licensed health care facilities are required to comply with the Joint Commission on Accreditation of Health Care Organizations (JCAHO).

The push to create shore and harbour protection that is environmentally more compatible often puts the reality of the needs for resilience and strength at odds with the needs of nature. Softer protection schemes, such as floating wave attenuators and non-bottom-founded protection methods, are typically inadequate to resist the ravages of a storm, whereas the construction of solid ring breakwaters changes the texture of the shoreline and affects the biota. Out-of-the-box thinking was required to find an approach that could both emulate the natural environment and yet still be resilient enough to protect against hurricane events, promote ecology and offer safe and manageable navigation. The solution was found in building a protection system of artificial islands configured to create wave sheltering, oriented to reduce long-term sedimentation effects by controlling tidal flow patterns and executed to be a living island archipelago with both benthic and terrestrial habitat. © ICE Publishing: All rights reserved.

The Pacific Northwest, specifically Portland, OR, has become a recognized leader in using small, vegetated best management practices (BMPs) such as infiltration basins for stormwater management. Landscape Architects around the United States often point to Portland's successes as to what could be achieved elsewhere. However, is stormwater management in the Pacific Northwest different from the rest of the country, and is it practical or even possible to replicate these practices somewhere else? To answer these questions, the authors re-created Portland's Simplified Sizing Model and then calibrated it for several major U.S. cities in various regions of the country. This approach allowed for a direct, side-by-side comparison of a hypothetical site, using the same design variables with different rainfall inputs depending on the city being studied. The results indicated that while small scale BMPs are effective in all regions of the country in managing small events, large rain events are much more difficult to manage as compared to Portland. However, by understanding the differences, opportunities arise that allow for practices to be adapted to a region's specific climatic conditions. © 2012 Elsevier B.V.

ASHRAE 170 is just the baseline for the fight against hospital acquired infections (HAIs). The ongoing human and financial tolls taken by these infections point to the need for engineers and facilities to raise their IAQ game wherever possible. Move beyond the minimum and get into the what, where, and how of HEPA filtration, ultraviolet technology, and catalytic air cleaners. © 2015, Business News Publishing Co. All rights reserved.

Last fall, the Ford Motor Company announced a $4.5 billion investment in EV and battery R&D, and now the company has upped the ante on itself. For the first time since the 1950s, Ford is embarking on a complete do-over of its product operations and global headquarters in Dearborn, Michigan, that seems aimed at soaking the entire company in EV culture. The effort will transition the company’s current roster of 70 buildings into two “green” campuses that will double as showcases and test beds for cutting edge mobility products, much of which revolves around EV technology and connectivity. And yes, Ford’s eBikes will be part of it. First things first — it’s true, Ford eBikes are a thing. In January CleanTechnica visited the North American International Auto Show in Detroit as a guest of Ford, which provided the opportunity to pepper Dr. Ken Washington, the company’s VP for Research and Advanced Engineering, with questions about Ford’s recent ventures into pedal-power. The answer was “very serious.” In fact, e-bikes were one of only two mobility solutions that made the cut for particular attention from Ford, after the company explored more than a score of other mobility options for marketing potential (the other area of focus is non-traditional/shared vehicle ownership). So, the new Product Campus will serve as a pilot location enabling Ford to test out its Ford-branded eBike in action, along with autonomous vehicles and on-demand shuttles. The Product Campus is also designed as an all-weather walkable community — an important consideration for chilly Michigan winters — so covered walkways are featured along with trails and biking/walking paths. Of course, for the foreseeable future, the bulk of Ford’s products will run on liquid fuel (fossil petroleum or biofuel), but the new Product Campus will pickle many of the company’s 30,000 employees in EV culture by focusing on sustainability. We’re calling it EV culture because after all, the whole point of the EV revolution is to make things better. Ford is extending that concept past simply reducing airborne air pollutants, to include overall health and wellness as well as new mobility options that have the potential to embrace populations far beyond the car-owning public. The new Product Campus replaces the 1953 Research and Engineering Center… That roundish building near the foreground sports a rooftop full of solar panels. That’s clearly not enough to power the whole campus, but it’s a start. The main sustainable energy technology is geothermal heating and cooling. Construction is beginning this month, with completion slotted for 2023. The other campus will preserve the iconic Ford World Headquarters building, but update its surroundings to encourage walking and biking. The company will renew its commitment to the 1960s era Arjay Miller Arboretum at the site, and focus on native plantings and more green space throughout. Renovations are expected to begin in 2021. Overall, the two campuses are not striving for the highest level in LEED building energy efficiency standards, most likely due to the unique demands of functional operations. However, the company is aiming for at least Gold certification, partly through energy savings: …increased building insulation, new glazing systems, state-of-the-art lighting and daylighting, and heat recovery will reduce overall energy use in new buildings by approximately 50 percent annually. Rainwater capture and treatment is also a main feature at both campuses, along with smart metering and high efficiency fixtures to reduce potable water use. Rainwater retention areas and lavish tree canopies are also part of the water management plan. With an eye on future improvements, the plans include a net-zero waste, energy, and water Sustainability Center that goes beyond LEED to meet the Living Building Challenge for net zero construction. The challenges of true net-zero construction can be daunting, and they include health issues such as indoor air quality. However, it seems that Ford already has a head start on ensuring that the wellness of building occupants is a major feature of the Sustainability Center. The designer of the new campuses, SmithGroupJJR, already has an impressive stock of green projects under its belt, and has incorporated the WELL Building Standard® into its design.
