Airbloc protects hygiene at Europe’s largest glass bottle factory

The new £300m Quinn Glass bottle plant, built on the site of the former Ince B power station in Cheshire, is protected from the ingress of dust and flying insects by powerful Airbloc air curtains over loading bay doors.

With the capacity to manufacture around 1.2 billion glass containers every year, the factory is a ‘one stop shop’ for the production, storage and filling of product for the drinks industry. The 145,225m² plant has 13 bottle production lines, two glass melting furnaces and covers a site of around 65 hectares at the edge of the river Mersey estuary. It is the largest of its kind in Europe and the first with an integrated filling line.

In a food handling environment, hygiene is a crucial factor. Dust and flying insects cannot be allowed to enter the production and filling areas, but with loading bay doors in constant use, keeping both out can be difficult. When external air flows into the building, it may bring with it dust and other unwanted airborne particles, and flying insects, both of which will compromise hygiene and sanitation. The European Food Safety Inspection Services (EFSIS) advises that where food is handled or stored, doors should be adequately proofed.

To ensure this is the case, 12 Airbloc AB300 air curtains were installed above 10 of the 3-metre wide doorways. The air curtains deliver a powerful ‘sheet’ of air across the entire opening, very effectively blocking the way for dust and flies.

An air curtain provides an invisible barrier across the doorway that maintains separation between internal and external environments. They operate using fans and nozzles to create a stream of air that is directed down or across the door opening, forming a barrier of air that separates the internal and external atmospheres by deflecting natural convection airflow. This air shield reduces the incidence of cold/humid air, dust, fumes or flying insects entering and warm or cooled air escaping.

Air is drawn into the air curtain unit and discharged at critical velocity, volume flow and temperature, and at an angle to ensure optimum performance. The kinetic energy that is transferred to the air by this process provides the necessary resistance to unwanted external air and particles.

In order to achieve efficient low energy usage, the air jet width, velocity and pattern of the airflow are crucial. Optimum effectiveness can be achieved when there is uniform linear flow across the full door width and fan speed control for additional wind resistance.

The Airbloc air curtains were fitted by Ashton Ventilation on behalf of the M&E Contractor Kramer of Halesowen.

A warm welcome to the Pomme D’Or Hotel

A powerful Airbloc air curtain, installed over the main entrance doors of the luxurious Pomme D’Or Hotel in Jersey as part of a £5m refurbishment programme, is proving very effective in blocking the prevailing winds that blow off the English Channel.

The result is a warmer, calmer welcome for guests and a pleasanter climate in the hotel’s extensive lobby.

The air curtain works by delivering a down-draught of heated or ambient air across the width of the doorway. The velocity of the air is such that it creates a barrier that separates internal and external environments when the doors are open, even when being pounded by winds of up to 15mph. Dust and flying insects are also effectively excluded.

The Pomme D’Or Hotel, built in 1850 and now part of the Seymour Group of hotels, is a significant building in Jersey’s history. On the day the island was liberated from German occupation, May 9th 1945, British soldiers lowered the German flag and raised the Union Jack on the balcony of the hotel. The 60th anniversary of Liberation Day saw HM The Queen deliver a landmark speech to islanders from the same balcony, overlooking Liberation Square and the harbour.

Physical restrictions on space and interior design considerations meant that the Airbloc air curtain had to be positioned to be as unobtrusive as possible. To answer these dual requirements, the building services department of engineering consultants DJ Hartigan & Associates of St Saviour, Jersey specified an Airbloc AC 2-metre wide chassis unit which has a 20mm wide aperture through which the air is delivered.

Usually, a chassis unit is surface mounted. However, for this application the unit was recessed in the ceiling space above the door and concealed behind a narrow grille. A conventional recessed unit would have required a 400mm x 2m grille.

The air curtain was installed by AC Electrics of St Saviour, Jersey.

David Renouf, Maintenance Manager for the Seymour Group of Hotels, comments: ‘The Airbloc air curtain works extremely well in preventing the prevailing winds that come in off the Channel. Although the island’s climate is generally mild, the winds can be chilly and strong. The air curtain ensures the lobby area remains unaffected by windy conditions.’

SmartElec – intelligent energy saving control for air curtains

Interested in saving 40% or more on your running costs and a short payback period on your investment? SMARTELEC has the answer.

The SmartElec control is the latest energy saving enhancement from Airbloc, supplier of high performance, high efficiency over-door air curtains. With in-built intelligence, the SmartElec reduces power consumption and energy costs associated with electrically heated air curtains.

High street store trials show that with a SmartElec control installed, average energy savings in the region of 40% can be realised. These results were achieved on an exposed site during the winter months. Savings greater than 40% maybe achieved on less exposed sites, during warmer months and with reduced outlet air set temperatures.

Suitable for new applications and possible retrofit to existing installations, SmartElec is packed with useful features that make installation and programming a cinch – adding real value to the contractor’s work, and putting precision control into the hands of the end-user.

The discreet surface or recess mounted program panel is wired to the air curtain using 24V Belden 8132 paired 4 core cable. Installation is quick and easy and the easy to use programming means that potentially expensive commissioning is avoided.

The program panel can be wired up to 50m away from the air curtain. The stainless steel slimline profile of the program panel is aesthetically pleasing and compliments most modern interiors.

The SmartElec control can link to building management systems. This enables integrated control of the climate around doorways that are in constant use with the rest of the building’s energy management systems.

SmartElec maintains constant air outlet set temperatures with built-in speed setting temperature compensation to prevent the effects of chill from the velocity of the air stream. The control monitors the air outlet set temperature and modulates to ensure comfort conditions are sustained, or quickly regained, when doors are opened.

Programming is straightforward – users select heat on/off, the required fan setting (two or three speed) and outlet air temperature setting. With such precise control of the air temperatures, the energy requirements of the air curtain can be managed effectively. The energy savings generated will significantly reduce running costs and provide a short payback period on your investment.

The SmartElec is suitable for use with Airbloc AC and Airbloc ACR three-phase electrically heated units.

Airbloc offers warm welcome to Bingo players

Maintaining a warm, welcoming environment in the main foyer at Opera Bingo in Workington, Cumbria, is essential to the comfort of players and staff.

Two Airbloc air curtains installed above the main entrance doors of the premises ensure that cold air remains outside, while inside comfort conditions are not affected by the opening and closing of the doors.

The models used are Airbloc AC2000 SE18 units, two metres wide and with a powerful 18kW output. Positioned above the main pedestrian and disabled entrances of the 111m² lobby, the air curtains deliver a sheet of warmed air at critical velocity across the entire width of each doorway. This ensures that cold external air is effectively blocked out, even when the wind is gusting up to 15mph.

An inviting environment is important in attracting customers to the new bingo hall, which can accommodate up to 850 people. The premises represent a new generation of the game in the UK, with Las Vegas-style fruit machines and plasma TV screens adorning the walls in addition to bingo. Opera Bingo Manager Shaun Edwards comments: “We aim to offer an experience that could be enjoyed by anyone and everyone and the new club has certainly achieved this. The air curtains are effective in keeping the foyer warm and shielded from cold draughts.”

Air curtains v roller doors – no contest

When it comes to the crunch…there isn’t one with air curtains. This economical, highly effective doorway barrier can’t be damaged by fork-lift trucks – just one of its many benefits, as John Halley of Airbloc explains.

Providing protection across loading bay doors is an expensive business. A roller shutter door may have to open 20-30 times a day, while withstanding the occasional pounding from a mis-timed fork-lift. If it has to stay open for long periods, warm air from within the building escapes and cold air rushes in, making working conditions less than ideal. If the mechanism jams, as it often does, operations are held up while it is fixed and valuable heat escapes through the door.

The primary features of an effective loading door barrier are that it must keep out the cold, robust enough to withstand mistreatment and quick to respond when goods or people want to pass through.

A roller shutter door can provide all these benefits – but are prone to damage and mechanical failure. Air curtains offer all the advantages, with none of the problems.

Air curtains create a barrier of ambient or warmed air across open doorways. The air curtain unit is positioned either across the top of the doorway or down the side. A powerful ‘sheet’ of air is delivered across the entire opening, which deflects the natural convection of airflow.

This is a deceptively simple process. In fact, the ‘sheet’ of air flows at critical velocity to maintain separation of the internal and external environments. In other words, cold air stays out and warm air is kept in. With Airbloc air curtains, this has been known to reduce energy losses around loading doors by up to 80% and improve the overall efficiency of a pre-existing heating system. This can result in significant cost savings and the additional benefit of improved comfort conditions for personnel.

Unlike roller doors, visibility is never a problem with an air curtain. And because the air curtain safeguards comfort temperatures within the building, the loading bay door can remain open all the time, even during the night, allowing for 24-hour delivery and dispatch operation.

An air curtain can’t jam, and of course the air flow can’t be damaged by careless fork-lift driving.

Airbloc air curtains for industrial applications are available as two speed units. When doors are closed the unit operates at low speed to provide additional heating in the building as part of the heating system. When they’re open, the air curtain performs its primary function, operating at high speed.

The Airbloc range comes in three heated forms: gas, electricity or LPHW powered. There is also an ambient unheated alternative. The ambient variant is typically installed in spaces where an effective heating system is already in place and there is a requirement to prevent external cold air from entering the building and altering the internal temperature. Installation of an air curtain can also significantly improve the efficiency of the existing heating system because internal temperatures are not compromised when doors are opened.

This was the case at Airbus aerostructures at Broughton in North Wales, where the wings for the new A380 passenger plane, the recently-launched 550-seat commercial aircraft, are assembled. To accommodate wing assembly, a floor area of approximately 84,000m? is required, and a roof height of 30m. An effective means of maintaining internal temperatures while the 40m-wide doorway is open was required.

Eight 5m long Airbloc Industrial air curtains were installed, positioned above the main dispatch doors. Over the goods inward doors, six Airbloc ABX ambient units were fitted. These were specially engineered to form an effective barrier from a height of 8m.

The air curtains provide highly effective environmental separation, ensuring working temperatures are maintained in the production area. The ambient units in the goods inward area re-circulate warm air gathering at high level to ensure economy of operation.

When it comes to the crunch, air curtains are a cost effective and efficient alternative to roller doors – safer, warmer, robust and a help, not a hindrance, to the constant flow of goods in and out.

If you can't stand the heat ... fit an Airbloc

Airbloc air curtains are used in a very wide range of applications to maintain environmental separation between one area and another, usually between internal and external environments. However, they can be effectively used in entirely indoor applications to isolate extremes of temperature – as the kitchens of the Keswick Hotel has found to its advantage.

The Keswick Hotel in the heart of the Lake District combines all the charm of a Victorian country house with the facilities of a modern hotel. It is renowned for its cuisine and head chef Chris Lyon runs a tight ship. He insists that the doorway between the kitchen and food preparation area remains clear at all times, while the temperature in the food prep room remains at a low 10°C.

With a constantly open doorway and intense heat build-up in the adjacent kitchen this could have been an impossible feat.

Electrical contractor Refrigeration (Mitton) Ltd installed an Airbloc AC1000 overdoor air curtain to counter the effects of heat from the kitchen in the cool food prep room. The unit delivers a sheet of ambient air across the entire doorway, sealing heat in the kitchen and cool air in the preparation area.

Keith Walker of Refrigeration (Mitton) Ltd comments: “The Airbloc air curtain is highly effective in keeping the food preparation area cool – an essential part of the hygiene and smooth running of the hotel’s kitchen.”

SmartElec trials achieve 40% energy saving for New Look

Trials of the new SmartElec intelligent air curtain control panel at New Look’s fashion store in Watford have produced an incredible 40% saving on the energy consumed by the overdoor air curtain.

New Look relies heavily on air curtains at the entrance to all its stores in order to maintain an ‘open door’ policy, considering an air curtain an essential element of the store’s image and a key method of encouraging footfall. Industry statistics show that an air curtain can increase footfall through open entrance doors by an average 25%.

But maintaining a constant temperature at the door entrance requires the most economical equipment in order to keep energy consumption to a minimum and energy costs at acceptable levels. The exposed location of the Watford store in the arc of a ‘horseshoe’ shaped outdoor mall adds extra challenges to maintaining the store’s desired entrance temperature. External air is ‘funnelled’ into the store; however, the Airbloc AC electrically heated air curtain counteracts air ingress very effectively.

A SmartElec control panel was fitted to the air curtain in October 2005, for a six-month trial to test the effect on energy costs (proven by a data logger) and the potential benefit it could bring in meeting new Part L Building Regulations. SmartElec maintains constant air outlet set temperatures with built-in speed setting temperature compensation to prevent the effects of chill from the velocity of the air stream. The control monitors the air outlet set temperature and modulates to ensure comfort conditions are sustained, or quickly regained, when doors are opened.

Programming is straightforward – users select heat on/off, the required fan setting (two or three speed) and outlet air temperature setting. With such precise control of the air temperatures, the energy requirements of the air curtain can be managed. Once set, the unit is tamper-proof.

The immediate effect of installing a SmartElec unit was noticeable reductions in energy usage, without any compromise to the efficiency or effectiveness of the air curtain. The unit ensures the air curtain operation optimally at all times, never wasting energy, and never conflicting with store-wide heating or air conditioning.

An air curtain can prevent up to 80% of ‘normal’ heat loss through an open doorway. SmartElec will maintain an air curtain’s energy efficiency even further – by 40% in the New Look Watford trial. This translates into long-term cost savings for the company, and a minimisation of energy usage to achieve the stores’ comfort levels.

A healthy outlook for Airbloc Commercial

The prestigious new Edgware Community Hospital, one of a new breed of NHS day hospitals, has been fitted with Airbloc Commercial overdoor air curtains in the main entrance atrium and the Emergency Centre.

The new complex replaces the former Edgware Hospital at Burnt Oak. Its purpose is to provide outpatient treatment for a range of ailments, so overnight beds are limited. The hospital offers urgent treatment centre, day surgery, a children’s centre, postgraduate centre with medical library, citizen’s advice bureau and a birthing suite.

Designed by Nightingale Associates, who specialise in health and educational projects, the building is an example of modern hospital design at its best – spacious, light and calming. Visitors using the main entrance step through an enclosed entrance lobby, designed as an isolated pod on the curtain walling, into a central atrium.

To avoid cold draughts penetrating from outside and creating discomfort for hospital visitors and reception staff, a heated Airbloc air curtain was positioned over the main entrance.

Jason Truscott of Nightingale Associates explains the choice: “Considerable thought went into the design and visual appeal of the entrance lobby. It was essential that the air curtain blended with the aesthetics of the area.”

An Airbloc AC surface mounted air curtain matched the architectural requirements, being both effective, efficient and visually pleasing. The model selected is semi-circular in profile, and available in a range of colours – in this case, a white casing was specified.

At the entrance to the Urgent Treatment Centre, Airbloc ACR recessed air curtains were installed above the doorways. Again, the primary function was to maintain internal temperatures and prevent cold draughts infiltrating. In this environment, it was important that the air curtain was discreetly positioned in the ceiling void.

Airbloc air curtains deliver a sheet of warm or ambient air across the entire width of a doorway at critical velocity and volume. The effect is to create ‘environmental separation’ between the internal and external atmospheres.

Airbloc – for an altogether warmer welcome

What’s more off-putting for customers than a howling gale whipping in from the street when anyone enters through the main doors? They may be mildly inconvenienced – or more likely they’ll find the icy blast uncomfortable, and leave with a negative image of the premises.

Now, imagine that they were unaffected no matter how many times the doors opened and closed, or even if the doors remained open all the time to attract more custom? Hotels, restaurants, clubs and pubs all over the UK have achieved this by installing an Airbloc Commercial overdoor air curtain.

A considerable amount of energy is consumed in creating an interior environment that achieves optimum comfort for customers and staff. Indoor air temperature is affected the moment the doors are opened.

Opening external doors creates a ‘wind tunnel’ effect. External air is drawn in, immediately impacting on comfort levels. The heating or air conditioning system has to work twice as hard to restore the working environment.

If the doors are in constant use, opening and closing throughout the day, most heating or air conditioning systems are unlikely to cope effectively. Overall energy consumption increases and internal conditions become uncomfortable as temperatures fluctuate.

Airbloc energy efficient air curtains form a barrier of air across an open doorway that shields the interior environment from the outside elements. This may involve keeping winter weather out to preserve indoor warmth, or retaining conditioned or cooled air inside during the summer.

This is particularly important in food preparation areas, where an Airbloc air curtain can provide a suitable barrier to stop heat/cold, dust and flying insects entering the premises.

Extensive model range
For public and commercial buildings, Airbloc offers an extensive range of models, including recessed, surface-mounted and ceiling tile options.

The ACR recessed range can be discreetly mounted in bulkheads and above false ceilings to serve a doorway without obtruding on the eyeline or aesthetics of the entrance. On a smaller scale, the ceiling tile version (ACT) provides effective protection across doorways, yet fits neatly into modular t-bar ceiling tile systems.

The surface mounted AC air curtain is aesthetically pleasing, having no grilles. The latest model is an innovative shape that compliments contemporary interiors and is available in RAL9010 white or metallic silver as standard colours. Other colours can be specially ordered to blend with internal decoration. This model also complies with Health and Safety regulations for emergency lighting and audible alert. It can be backlit to display company logo or venue name.

Baroosh Bar
The AC model was selected for installation in the Baroosh Bar in Uxbridge High Street, a former gas showroom that is now part of the McMullan Brewery chain. The façade has been turned into an impressive two-storey glass frontage with double doors leading directly from the street.

With no lobby area to protect clients from draughts when the doors open and close, an air curtain was a practical solution. The delivers a powerful downward flow of air across the doorway, preventing the influx of cold air from outside. A back-light facility allows the name of the bar to be displayed above the doors, while spotlights and a fire exit sign facing the interior provide essential safety lighting in the event of an emergency.

Great Eastern Hotel
Liverpool Street Station’s magnificent Great Eastern Hotel, beautifully transformed into one of London’s leading hotels, also uses an Airbloc air curtain to maintain comfort for customers visiting its Fishmarket Restaurant and Champagne bar. This magnificent 70-seater restaurant features a dramatic horseshoe shaped bar clad in aquamarine and silver mosaic.

The recessed Airbloc is positioned above one of the entrance doors. It was supplied in a bespoke finish to match the décor of the interior.

Energy saving air curtain
Whatever the application, air curtains will retain warm or conditioned air, ensuring that less burden is placed on the heating or air conditioning system. The result over time will be reduced energy consumption and lower fuel bills. If a heated air curtain is used, it can be programmed to provide supplementary heated air when the doors are closed, ensuring further economies are gained.

New Commercial Airbloc scores at Baroosh

The elegant stainless steel, back-lit ‘design feature’ over the entrance doors to the new Baroosh Bar in central Uxbridge, near London, effectively protects customers inside from the external weather conditions as they enjoy a drink in comfort.

The Airbloc commercial overdoor air curtain is a bespoke model that can be finished to blend with the most cutting edge of interior decors. It also has practical features that make it both highly effective in blocking out cold draughts when the doors open and close, and add to customers’ safety when in the building.

Baroosh is a concept bar that offers a sophisticated, style-conscious café/bar environment for drinking and dining throughout the day. The façade of the Uxbridge premises has been turned into an impressive two-storey glass frontage with double doors leading directly from the street.

With no lobby area to protect clients from draughts when the doors open and close, an air curtain was a practical solution. The air curtain delivers a powerful downward flow of air across the doorway, preventing the influx of cold air from outside.

The new Airbloc AC offers a wide range of finishes to fit with almost any décor, including a polished metal effect. A back-light facility allows the name of the bar to be displayed above the doors, while spotlights and a fire exit sign facing the interior provide essential safety lighting in the event of an emergency.

Smile! Airbloc offers a pleasanter welcome to customers

Airbloc overdoor air curtains are the energy-saving solution that will ensure customers always feel welcome. The soothing jet of air – whether ambient or heated – customers experience as they enter retail premises may well encourage them to spend more, while you save on fuel costs. Marianne Sibborn of Airbloc explains.

Air curtains are a familiar sight in retail premises. On the face of it, they have a very straightforward purpose – to keep warm air inside and cold air out, or vice versa in summer or if the building is air conditioned.

But this innocuous machine does much more than just keep out the cold or heat. Airbloc air curtains are the low energy-consuming solution that protects doorways in all retail premises.

Airbloc air curtains can work in harmony with other heating or air conditioning equipment to produce energy saving and environmental benefits.

Over time, this can result in long-term fuel cost reductions, without ever compromising customer comfort.

There are other benefits, too. Air curtains can significantly reduce the ingress of dust, fumes and flying insects – a major advantage in summer when such factors can make life unpleasant. But its most immediate effect is that felt by customers – an aesthetically pleasing aspect and a welcoming feel as they enter your premises.

Here’s the science
The moment a door opens, external air floods into the interior, creating a wind tunnel effect and immediately impacting on the air within the building. In heated buildings, cooler, denser air flows in through the bottom half of the opening, while warmed air flows out at high level. If internal air is cooled (ie air conditioned in summer), the reverse occurs.

When entrance doors open, the beneficial effects of heating or air conditioning will be temporarily lost. Heating or air conditioning systems have to work twice as hard to restore comfort conditions. As doors are opened and closed many times a day, the overall effect is to drive up fuel costs in the long-term.

Footfall is increased by up to 25% by keeping entrance doors open. In this case, some kind of mechanical protection of the interior environment should be fitted. In food sales areas, or to separate food preparation areas from the sales floor, this is a must. Air curtains are the ideal choice.

How air curtains work
Air curtains are positioned directly over (or occasionally down the side of) the entrance doorway. A curtain or ‘sheet’ of air is delivered across the entire width of the aperture, forming a very effective barrier that deflects natural airflow when doors are opened.

The air curtains operate using fans and nozzles to create the stream of air. Internal air is drawn into the unit and discharged at critical velocity, volume flow and temperature, and at an angle to ensure optimum performance.

The barrier of air has four physical effects:
As a thermal barrier – the air curtain provides a shield against heat loss or cold air gain in winter and against heat gain in summer
Wind resistance – providing the appropriate velocity and volume of air is set and the air curtain angled correctly, prevailing winds can be deflected
Flying insect control – unhygienic flies and other flying insects are kept at bay, an important factor in complying with Environmental Health Regulations.
Environmental separation – where the presence of a physical doorway would be inhibiting (ie. if doors needed to be kept open to encourage passing trade) air curtains serve the purpose of a door by separating internal and external environments. They can also separate cold storage or ‘clean room’ areas from other environments where air quality is less critical.

Selecting an air curtain
There are four heated forms of Airbloc air curtain. These may be powered by electricity or low or medium pressure hot water. Ambient models are unheated and used mostly to prevent external air from entering the building where this would affect the efficient operation of the existing heating or cooling system.

For retail and other commercial premises, the Airbloc recessed, tile or surface mounted models are ideal.

The Airbloc ACR recessed unit can be mounted in bulkheads and above a false ceiling to serve a doorway. It is discreet and will not obtrude on the eye line or aesthetics of the entrance. A white non-vision grille makes the unit almost imperceptible from inside the building, ensuring a good fit with the interior design.

The smaller ceiling tile heater, the Airbloc ACT, fits neatly into modular T-bar ceiling tile systems to provide additional heat that may be distributed throughout the shop floor.

Airbloc AC surface mounted air curtains have the option of emergency lighting which complies with Health and Safety regulations. Available in white or metallic silver, this model can be back-lit to display the company name or logo. Units are aesthetically designed to fit with modern interiors.

Airbloc seals in comfort at Corporate HQ

AstraZeneca is one of the world’s leading pharmaceutical research companies, producing prescription drugs to treat a wide range of diseases and medical complaints, from cancer to inflammation.

Its Corporate Headquarters in central London are housed in a substantial Georgian building dating back to 1747. Completely refurbished in the early 1990s, the premises now house AstraZeneca’s key global functions. It is also utilised as a London-based conference centre.

With dozens of personnel arriving daily, the lobby area is exceptionally busy. Despite a double entranceway from the street, reception staff found they were continually bombarded with blasts of cold air as the doors opened and closed throughout the day. Similarly, whenever the doorways were in use, warmth from the interior escaped.

To maintain comfort conditions for staff and visitors, and stop energy loss through the doorway, a form of protective barrier was required.

An Airbloc ACR recessed air curtain was installed in the ceiling void between the two doorways. The air curtain delivers a ‘sheet’ of air at critical velocity that prevents internal air escaping or external air infiltrating. As a result comfort conditions within the lobby area remain constant, however often the doorways are used.

The Airbloc ACR had to be fitted into an existing space in the plastered ceiling bulkhead where an air conditioning unit had once been positioned. As the space was slightly smaller than the Airbloc ACR, installation engineers Howe & Co installed a false lighting trough to accommodate the larger unit. From below, only the Airbloc grille is visible.

Nigel Bunker of Howe & Co comments: “This was an unusual installation that required careful consideration. However, the Airbloc is well-disguised, and performs the task of maintaining temperatures inside the lobby area very effectively.”
