Lexon are one of the largest independent pharmaceutical wholesalers in the UK. Providing a catalogue of over 8000 products to more than 3000 pharmacies requires large distribution hubs that have to maintain temperature below a set point in order to comply with Medicines and Healthcare Products Regulatory Agency (MHRA) guidelines. Whilst the existing extraction system removed heat from the building, it was now time for an upgrade. A system that would be reliable, economical and able to cope in a heatwave. The brief With a warehouse of over 7000 square metres to cool and such exacting requirements, the choice of contractor and plant was critical. Fortunately the right heating, ventilation and air conditioning contractor were soon identified by Lexon who, after speaking with a satisfied customer in the same industry, and then seeing the product in action, quickly set our engineers to designing a cooling system to meet their brief. An order duly followed and the job was under way. Design and Engineering An important first step is the identification of hot or cold spots. Potential problem areas were considered. For example high storage areas, or the packing, loading and return bays. Also factors that can influence temperature such as doors and windows. The Solution 29 CoolBreeze QAD230 evaporative coolers were the prescription. The units introduce fresh, filtered, cool air into the building, bringing temperatures within MHRA guidelines. The racking at high levels received our particular attention. A continual flow of cool air is pushed along each aisle while carefully balanced ducts provide even distribution. Extra roof vents then expel the hot stale air. During the design, alternative air conditioning technologies were considered. They too could have maintained the temperature in the building. However, they were expensive to install and prohibitively costly to run. For a building this size nothing else comes close to evaporative cooling. As water is the principle means of cooling, no CFC’s are required and so average running costs – for an 8 hour shift – begin at just £1 a day. The results are big energy savings, vastly lower bills and superb carbon credentials. The Result The first result was an early one. The Lexon premises are a busy and complex distribution hub. Clean Air met the challenge and completed the installation with minimal disruption to daily operations. However it was shortly afterwards, during the summer of 2018, that the 29 units established their true worth. Despite sweltering highs in excess of 30 degrees centigrade outside, the temperatures inside remained within MHRA tolerances. As an exemplar in how to cool a pharmaceutical warehouse, Clean Air are justifiably proud of this installation. Lexon too share in our delight. We now maintain and service all of the units we installed and our relationship with Lexon continues to thrive.

About the Project Just two blocks from the White House, PNC Place is building a 12-story, 365,000 square foot office building, which will be their new Greater Washington regional headquarters. This will in fact be Washington D.C.’s first office building designed to achieve U.S. Green Building Council LEED (Leadership in Energy and Environmental Design) Platinum certification. The LEED Platinum certification reflects the highest level of environmentally sustainable building design recognized by the council. Opening in 2010, it will be a host to a number of office tenants and provide retail space, including a PNC Bank branch. This building features several solutions to reduce energy consumption, of which the most impressive is a 3-story “climate wall”, which is a wall of water to help naturally cool and condition the space. Having brought together natural elements and sustainable building design, the goal was to find an air distribution solution that would complement the application and fulfill the LEED requirements for energy-savings. Challenges & Considerations Working with local representative, DMR & Associates based out of Gaithersburg, MD and engineers at GHT, Limited, we found that they were challenged by the potential problems with delivering very cold air directly into a space, primarily due to condensation concerns, especially in critical areas such as the building entranceway, where building humidities are likely the highest. Previous designs had used series terminal units to mix some return air with cold primary air to raise the discharge temperature above the expected building dewpoint. This design has worked well, but is limited by the capacity of the fan in the unit, which must handle all the air being delivered to the space. Product Solution Several options were discussed. It was determined that the best option was a parallel, low profile unit with the backdraft damper removed (as it wouldn’t be needed) with a single DDC controlled ECM motor to often run at a reduced airflow (saving energy). The combined flow-rate of the primary and parallel fan could exceed that of a series unit, at lower unit fan energy, lower first-cost, and lower sound levels than any other option. The End Result Krueger is pleased to have had the opportunity to be involved with the engineers and designers of PNC Place to develop a product solution to fit such stringent energy requirements and help contribute to the LEED platinum certification. Scheduled to open in June of 2010, the true results of their planning have yet to be realized, but we are confident that the design and implementation of the 555 KLPP fan powered terminal units promote occupant comfort, lower first-costs, and capture energy savings.

Objectives To replace cooling towers located on the 52nd level of a commercial high-rise building in downtown Los Angeles. Solutions This client chose Mesa because of the company’s extensive experience in performing complex air conditioning system retrofits on a turnkey basis. From the start, Mesa faced two challenges. First, the building’s cooling had to be maintained while the cooling towers were being replaced. And second, the units were located at the top of one of the city’s tallest buildings, necessitating the use of a helicopter to lift the new units above Los Angeles’ busy streets. To address the first challenge, Mesa demolished and removed half of the existing cells, leaving the remaining cells to continue cooling the building. After mounting seismic isolation bases and springs, Mesa installed two induced-draft counterflow cooling towers. The units were ordered in multiple sections weighing less than 3,500 pounds, so they could be lifted by helicopter. Mesa made all arrangements for the helicopter operation, including obtaining street closure permits, security personnel, and contracting for trucking support services. To minimize disruption to building operations and ensure maximum safety, the company dismantled the old equipment and removed it utilizing the buildings freight elevators after hours. Mesa orchestrated the two helicopter lifts on Saturdays when building occupancy and street traffic were reduced. Each tower included three cells, each fan driven by a 40-horsepower, 460-volt variable frequency drive. Mesa provided temperature controls through an interface to the building’s DDC system, enabling monitoring of the system operation and energy consumption and operating cost reductions. Mesa installed new fan disconnect switches, water piping, two tower cleaning systems, walkway gratings, and stainless steel exhaust ducting from each cell up through the roof. After the tower installation, Mesa performed start-up and commissioning services for the first two towers and completed the same work for the second half of the cooling towers before turning the completed project over to the owner. Background City National Plaza encompasses an entire city block in the financial area of Los Angeles’ central business district. Completed in 1972, it consists of two 51-story office towers, one plaza level building, and four subterranean levels, comprising in total more than 2.6 million square feet of rentable space.

In 2010, 4 Mort St, Canberra (Figure 1) was upgraded to significantly improve its energy performance. The retrofit was performed with the dual constraints of a limited budget and the building remaining occupied during the upgrade. This Case Study covers the key factors that enabled this 45 year old commercial office building to achieve a 2.5 star increase to 4.5 star NABERS Energy Rating, including the pathway taken and the technologies used. Background The building: ` constructed in 1966 and owned by Trafalgar Platinum Fund ` 5 stories with net lettable area (NLA) of 5,400m2 ` 2 star NABERS Energy Rating, as assessed ` Commonwealth tenants, with single retail tenant leasing part of ground floor, Commonwealth leases were set to expire ` existing HVAC reaching end of operational life, unreliable and expensive to maintain ` difficulty maintaining occupant comfort using existing HVAC system. In order to retain capital asset value the building owner decided to upgrade the building to target a 4.5 star NABERS Energy Rating The upgrade was also done in the context of: requirements to meet the Energy Efficiency in Government Operations Policy requirements for Australian Government tenants1 , and the ACT Environmental Leasing Policy requirements for Territory Government tenants2 the impending Australian Government Commercial Building Disclosure (CBD) regulations requiring an energy performance rating to be disclosed when advertising for lease or sale3 minimal disruption to business was also required so that tenants could continue to occupy the building throughout the upgrade a limited budget of $1 million, supplemented by $500,000 from the now closed Green Building Fund4 . Results Improvement from 2 to 4.5 star NABERS Energy Rating, and aiming to achieve a 5 star NABERS Energy Rating in 2013. ` Improved systems monitoring through the installation of a modern building management system (BMS). ` Annual energy cost saving of $120,000. ` Increase in asset value estimated at $1.4 million. ` 70% reduction in annual greenhouse gas emissions equating to 786 tonnes CO2 -e Conclusion 4 Mort Street Canberra was in a situation common to many aging commercial buildings. The building was performing poorly (estimated at 2 stars NABERS Energy), the existing HVAC system was nearing the end of its operational life (unreliable and expensive to maintain), energy prices were increasing, and some of the government tenancy leases were due to expire. In order to retain the building’s capital asset value it was necessary for the energy performance of the base building to reach a minimum 4.5 star NABERS Energy Rating in line with the Australian and State and Territory Government leasing policies. Faced with a limited budget for capital expenditure and a requirement that the existing tenants remain in situ throughout the improvements, the task of upgrading the building was not a small one
