How to incorporate a sense of inclusion and individualisation within the workforce

Clash of Cultures?

With the Millennials now hitting the workplace countered by an ageing workforce of an estimated third being over 50 by 2020, the average office has never been as diverse.

So it comes as no surprise that the challenge for many senior management and facilities teams is how to create a space for the differing work styles, roles and attitudes that this diversity brings, yet keeping a cohesive vision for the company and creating a culture and a sense of community.

Krishna Money, director at brand agency, Platform, that works with clients to provide workplaces that have their teams at the heart of their space, debated this dilemma at a recent roundtable event hosted by Platform with input from thought leaders from Google, Vodafone UK, Centrica and Expedia amongst others.

Build a workspace that incubates a culture

Step one towards creating a company community is to build a workspace that will effectively incubate a culture. Take Google’s offices that boast beds to rest and workspaces that blur the lines between work and play. Or Expedia’s offices, which Matt Saul, Project Manager at Expedia explained take global threads such as humour and colour but integrate local and quirky design elements such as a deconstructed bike, edam cheese wallpaper and a wall of clogs in their Amsterdam office meeting rooms. 

This was collaborated at the roundtable with guests highlighting that larger enterprises need to effectively stamp their DNA on an office space, but be flexible enough to realise that as with any offspring, fundamental traits might be different but the whole will work as part of the same family. There might be different architects commissioned for different buildings, but their brief will be to find a design that includes the DNA of the company. 

Incorporate Functionality

It sounds obvious but how many teams have moved into new offices to question the thinking behind the design? Another one of our roundtable guests, a financial institution, illustrated how workspaces need to be dictated by their function, and ultimately the nature of the job in hand. For some regulated institutions this may mean having sufficient private areas to discuss confidential customer activity while also facilitating a more open and collaborative environment for staff. The functionality of a space must suit the nature of the roles of those working within it.

However, sometimes a change in functionality can only be achieved by a shake up of space, a breaking of the psychological barriers associated with a particular work area. Take the call centre. One of the most challenging workspaces to manage, a call centre needs to balance the thin line between the motivation of the team and the efficiencies needed to be produced in the space. It is a telling point that when a large enterprise wanted to change the role of some of their customer centre employees from the day-to-day task of responding to customer queries to assessing best practice, they needed to change the workplace design to facilitate this change. Down came the screens between the customer liaison team and the headset had to be taken away in line with culture change around their role.

Remember one size doesn’t fit all

However, this is often a difficult remit – building an environment that has the required functionality, which reflects the company’s brand values and ethos, but can be tweaked to recreate a sense of familiarity to those working in it. To create a place that fit the individuals within it, without having a “one size fits all” can be the proverbial ‘square peg in the round hole’ dilemma.

What happens to personalisation and flexibility within the workforce? How do forward thinking companies ensure that they are not producing an inflexible space designed for all but only suitable for few? And what about those in the workforce who work remotely, or who only visit infrequently, how do enterprises integrate them into the culture? Matt Saul talked about this exact challenge at Expedia with the installation of temporary desks for those infrequent office workers, “We are introducing hot desks into the offices but we have chosen to do so softly. They are branded with a red adaptor, a red cover for the desk, but ensuring that there is a choice for those who come into the office so rarely they don’t feel like they need a desk. If management is pushing the change, there will be an emotive reaction to it.”

Build a Vision           

James Yates, Senior Property Strategy Manager at Vodafone elaborated on this dilemma by explaining that enterprises need to build a workplace that reflected where the company is going, and to communicate that vision through your workspace while providing a sense of ownership created from that. However, members of the workforce need to be able to take individual ownership over their workspace, a sense of responsibility to make sure the environment is right for them.

Acknowledging that we don’t all work the same way and that the workplace should embrace those different working styles and in fact, this diversity can often support your culture is key. The design needs to be conscious of our differences, be flexible in its approach and fluid in its functions. However, the actual space needs to be practical – to have enough places to sit and to be an environment where the majority, if not the totality can work. It needs to be done in synergy with technology where technology facilitates this fluidity of working, rather than dictating it.

There is a lot more at play in today’s workplace. It is not just about the range of age of the workforce and the consequential traits or trends this might result in. Culture in a workforce is a combination of the physical workspace, which effectively becomes a corporate hub to nurture and envelops the personalities and their emotions of those who work within it. Get this right and the workplace can bring support and inspiration that ultimately will not only boost the team’s careers but also the company’s growth and culture.

Specially-adapted façade solution from Wicona helps to create a new landmark

 

Specially-adapted façade systems from Wicona have been specified for a new £26m library – a magnificent and inspirational undergraduate facility for the University of Leeds, one of the largest universities in the UK.

The 6,500sqm state-of-the-art learning hub will help the University attract more students in an increasingly competitive higher education environment and provides a major cultural centre to enrich the student experience and the wider community.  It is a new gateway to the University, and its design is a bold and confident statement for the future of the institution.

Designed by ADP, the scheme occupies a sensitive location in a conservation area, surrounded by listed buildings including two churches and in a streetscape that has remained almost unchanged in 50 years.  It is the fourth building on a challenging teardrop-shaped site, and its design had to be developed with careful articulation and considered fenestration to the façades.

The four-storey library features stepped façades to the north and south elevations that unlock a series of generous public spaces. It was conceived as a ribbon of learning around a central circulation and internal study space.  Each floor plate steps up towards the south of the site and the internal atrium.

Portland stone cladding adds weight to the building and helps to present it as a place of importance to the University, complemented by extensive use of glass constructed from Wicona’s WICTEC 50SG structural glazing.

The curtain walling was designed to create an even distribution of light and an elegant appearance, as an alternative to punched openings or a grid across the building envelope. Large, flush picture windows were also formed using the Wicona WICTEC system, providing dramatic, panoramic views across the campus and the cityscape.

A ‘veil’ of anodised aluminium vertical fins floats in front of the glazing and the stone cladding for optimum solar shading to the east and west elevations, whilst allowing key and oblique views and unifying the façade elements.

The WICTEC 50SG structurally glazed system created a flush glass finish and was specially adapted for the project to anchor the solar shading fins.  It also had to meet stringent acoustic requirements and a rating of Rw DB 38 because of the building’s city centre location and the impact of high traffic levels.

Commenting on the project, Torsten Bauszus, Senior Architect at ADP, said, “This was a complex scheme located in a historic and urban context so the building envelope required very high quality, bespoke materials and design detailing.”

“The Wicona curtain walling had to meet a number of stringent specification criteria, including aesthetics, thermal and structural performance, and a high level of noise protection. It was also critical that the glazing was sufficiently robust to support the vertical blades for solar shading and that the connections could be integrated and carefully engineered. We are really pleased with how the glazing is performing.  Wicona’s systems delivered our expectations and we will be specifying them for future projects.”

The curtain walling was finished in bronze anodising externally and light champagne internally.

Wicona’s WICLINE 90SG opening vents were inserted into the curtain walling to naturally ventilate the stair core, and WICSTYLE 75 aluminium doors were used for two entrances on the ground floor and for access to the roof where there are 50,000 bees living in hives.

This is a sustainable building which is constructed to a BREEAM ‘excellent’ standard with low energy passive design and renewable energy generation. There was also robust thermal detailing to the envelope to deliver energy efficiency, as well as a sharp and contemporary appearance that reflects the ambition, vision and values of the University.

The four-storey building on the city centre campus accommodates more than 1,000 individual study places; 5km of linear space for 150,000 books; facilities for collaborative group learning; community classrooms to host outreach work with local schools and colleges; a café, courtyard and galleries for artwork and collections on public display.

Engineered in Germany, Wicona’s WICTEC curtain walling suite has been used extensively for complex façade projects in both the UK and across the world.  It has a wide range of structural aluminium profiles to accommodate vertical, angled, sloped and faceted glazing for optimum creative freedom and performance.  There are options for structural and unitised glazing, and enhanced security, fire protection and bullet resistance for visual consistency across a building envelope.

Eaton Expands LED range for Efficient Lighting in Industrial Buildings

Power management company Eaton is aiming to improve the quality and efficiency of lighting in industrial buildings by expanding its range of robust LED luminaires. The new additions to Eaton’s comprehensive lighting portfolio are the Tufflite and Linergy LED luminaires. Additionally, its existing Litex family of products has been updated with the addition of next-generation LED technology.

Andy Gallacher, lighting product manager at Eaton, said: “There is huge potential for industrial buildings to increase energy efficiency by switching from older fluorescent or high intensity discharge luminaires to the latest LED technology. This can not only reduce running costs but also saves on maintenance due to its longer lifespan. In warehouses, for example, lighting can account for up to 70 per cent of energy usage, while the figure is around 35 per cent for manufacturing sites. However, while the potential savings are significant, there’s also an urgent need to improve the quality of lighting in many industrial buildings, which have traditionally suffered from poor performance in this regard. Better lighting can have a major impact on the general wellbeing, productivity and safety of building occupants. Eaton’s latest Linergy, Tufflite and Litex LED luminaires have been purpose-designed to help those responsible for industrial buildings meet these objectives.”

Linergy LED follows in the tradition of Eaton’s highly efficient large-space luminaires which have the performance and flexibility for today’s multi-use and multi-occupancy locations. Incorporating the latest LED light engine technology, the luminaire delivers high lumen outputs and class-leading efficacies of up to 115 lumens per circuit watt (Llm/cW). When combined with the integral occupancy and daylight sensors, this can offer substantial energy savings for the end user.

The versatile Tufflite LED luminaires, with IP66 rated ingress protection, are suitable for areas where protection of the luminaire from environmental effects is vital. Offering a comprehensive range of lumen outputs across three lengths, the versatile LEDs are ideal for new and retrofit applications in warehouses, car parks, assembly areas and loading and storage spaces.

Additionally, Eaton has added new-generation LED options to its Litex range to improve the luminaires’ versatility and performance in industrial and warehouse environments. The enhanced Litex LEDs offer a 15 per cent rise in lumen (lm) output and are available with a choice of lumen packages controlled by open area, rack aisle or narrow distribution reflector options. Additionally, the new luminaires are designed to accommodate different mounting heights and installation methods, resulting in a solution that can be tailored to diverse applications.

Allegion strive to redefine how door hardware is sold

Specialist security manufacturer, Allegion, is launching a new programme that will hopefully redefine door hardware sales. Allegion’s new first-of-its-kind Try Me Product Programme, gives end users the option to try door closer products on a single door before committing to fitting them throughout their buildings.

The Try Me Product Programme is launching especially for the commercial, healthcare and education sectors, where young people and those needing specialised accommodations are more likely to be negatively affected by doors and door sets that have been incorrectly specified in the past.

Paul Barrows, demand creation leader at Allegion UK, commented: “We’re always creating and innovating new products, and decided that it’s important to reflect this ethos in the way our products are being sold. We knew that problem doors in commercial buildings can be a burden for facilities managers, so we wanted to give them an easy way to fix it.

“Doors can cause inconvenience through draughts or loss of privacy, but incorrect specification can jeopardise the security and fire safety of the building. We’re encouraging building owners to address the issue of problematic doors and ensure they are putting the best possible solution in place the first time.”

The new programme also allows Allegion to deliver technical advice and consultation to support product selection, alongside demonstrations by trained installers, as well as before and after product comparisons.

For further information or to take advantage of the Try Me Product Programme, contact the Allegion Customer Care Team on 01922 707400 or visit www.allegion.com/uk.

Voltage optimisation – a facility manager’s energy saving ally

Following the mandatory energy usage audits recently carried out by qualified assessors as part of the Environment Agency’s Energy Savings Opportunity Scheme (ESOS), voltage optimisation emerged as one of the technologies most regularly recommended to companies as a viable solution to reduce energy consumption levels.

This article explains why, on the back of the recent ESOS audits, it is important that facilities managers fully understand the role voltage optimisation can play in their sustainability strategies.

Voltage optimisation is a well-established and highly effective method of reducing a company’s energy consumption, decreasing its carbon footprint and producing savings on electricity bills.

The concept behind the technology is simple. On the whole, power is supplied at a higher voltage than is necessary. Although the ideal voltage required for most electrical equipment in the UK is 220V, the average delivered is actually 242V – voltage can be delivered at levels as high as 253V. The mismatch between voltage required and voltage delivered results in a waste of energy and of course money. Voltage optimisation corrects the over-voltage and brings it in line with the actual needs of the equipment on site, through use of a device installed in series with the mains electricity supply.

High Voltage

High Voltage (HV) side optimisation technologies offer optimisation solutions to sites that own their own distribution transformers. Many technologies exist, but there is only one system currently on the market that provides HV, electronic variable voltage optimisation. This is a combined solution that replaces an inefficient on-site HV transformer with an amorphous core super-low loss HV transformer, with integrated electronic-dynamic voltage optimisation technology.

Depending on the age and type of the transformer that it replaces, an amorphous core transformer can provide between 1% to 5% savings simply because it is so much more efficient. In addition to savings on replacement of the transformer, the integrated voltage optimisation technology can be expected to provide further savings of anywhere between 12% and 15%.

Low Voltage

Low Voltage (LV) side optimisation is connected to the low voltage side of a building.
There are two variations of LV side optimisation technology available: fixed and variable (also known as electronic-dynamic, electronic or intelligent voltage optimisation). Fixed voltage optimisation systems reduce the incoming voltage by a set amount to the optimum level for site operations. However, output varies as the input voltage differs.

Variable voltage optimisation systems set the output voltage at the optimum level and maintain this by systematically managing the peaks and troughs in the power supplied, irrespective of the incoming voltage levels, to ensure that voltage is supplied at a constant, stable level.

Optimum savings

Voltage optimisation provides savings on a variety of loads but not all equipment will consume less energy. The greatest savings come from inductive loads such as lighting and motors, especially if motors are not always loaded at 100% of their capacity. A building that has fixed speed devices such as air-handling units, multi stage compressors (i.e. chillers), pumps and standard switch-start fluorescent fittings, will achieve high savings.

Some loads such as VSDs will also see savings but at reduced levels and some loads will yield zero savings but will benefit in other ways. It is important to understand the electrical loading characteristics of your site and to remember that no two sites are the same.

All sectors can profit from voltage optimisation technology – from hospitals that need to maintain a steady power delivery 24 hours a day to operate sensitive, multi-million pound equipment, to government buildings, hotels, supermarkets and warehouses that are keeping a keen eye on energy expenditure and carbon emissions in order to meet sustainability targets.

The manufacturing industry particularly benefits from its ability to lower the operating temperatures of motors, thus reducing maintenance costs.

There is no downside to voltage optimisation. It can be used in conjunction with other sustainable technologies such as solar or wind power, and pays for itself within three years. After that, the substantial savings are enduring and feed straight back to a business’s bottom line.

Designed, engineered and manufactured in the UK since 2002, Powerstar is the market leading voltage optimisation brand. Powerstar systems are able to deliver substantial reductions in energy consumption through fixed or electronic-dynamic optimisation at either the HV side (High Voltage) or LV side (Low Voltage) of a site without impacting on the business operations of the building itself.

Having worked with an impressive portfolio of blue chip clients, government departments and a range of SMEs the Powerstar team are industry experts in voltage optimisation, able to provide advice and guidance to facilities managers looking to implement voltage optimisation on the back of ESOS audit recommendations for their sites.

Reduce energy costs with a holistic approach to energy management

With the climate discussions in Paris at the end of 2015, energy efficiency and usage reduction is understandably a hot topic. However, what does this really mean from an energy management perspective for facilities management?

You may well be happy with your current energy supply, usage and back-up support, but how do you really know that this is operating as efficiently as it can be? With energy costs likely to form a huge proportion of complete operating costs, the central task of energy management is to reduce cost for energy provision without compromising on the work processes. The only way of truly identifying this is by conducting a survey out, at the outset, to ensure all relevant information and system characteristics are gathered. Without a detailed understanding of an entire environment and what it is trying to achieve, it is very difficult to identify if a supply, with its associated load types, is even viable for power quality improvements. 

An effective survey will explore energy efficiency, conduct load or harmonic surveys and complete power quality investigations to give a complete picture. For example, what are the types of loads and what percentage do they represent? This could include heating, ventilation and air conditioning (HVAC) requirements, determining transformer type and what the tap setting are, right the way through to the levels of harmonic current and voltage distortion and how they are impacting on energy costs. The list goes on, but only then with the right information in place, can the right type of action or equipment be identified to ensure it will give the best return, while also allowing for redundancy and built in headroom.

Ultimately, an effective energy management approach needs to be an integral part of facilities management and in fact an essential part of a company’s overall strategy. It needs to encompass critical decisions on energy investments, while avoiding energy risks. Whilst also being transparent about the total cost of ownership (TCO) of equipment and maximising operating efficiencies, energy usage and running costs.

As Martin Pearce, Sales Director at Critical Power says, “Practically for facilities management, effective energy management is about adopting a holistic approach using a combination of tactics. This includes; market analysis of current energy supply, combined with site surveys to determine inefficiencies (and potentially efficiencies!), while adopting a turnkey approach for any installation changes required, so the headache is taken away.  However, it does not stop there, as it is important to minimise any downtime in the future by ensuring business continuity, through remote monitoring and regular service maintenance support.”

The likelihood is that energy management and efficiency issues will continue to proliferate as power demands increase and change. This is why it is so important that whatever the output from the climate conference in Paris, that businesses, particularly facilities management continue and in fact increase their focus on energy management. The pressure to address this will continue to be principally from a financial cost-saving perspective, however there is now likely to also be a shift in focus to it becoming more of an environmental one too.

Looking to Control the Temperature of Your Lobby?

With a Boon Edam Heater it’s a Breeze!

During periods of cold and windy weather, why allow the temperature in your lobby to drop? Just because it is chilly outside, doesn’t mean your reception area should be cold too.

The revolving door has become a significant choice for many architects and facilities managers due to the way they naturally help to keep out draughts and reduce energy loss within a building.

The cost saving decision to install a revolving door not only reduces your monthly energy bills but it is also more eco-friendly for the environment due to the reduced amount of hot air that leaves the building with every door rotation.

Still feeling the cold? Why not consider adding a Boon Edam heater onto your door?

On occasions when the weather is windy, cold air can sometimes become trapped within the seperate compartments of a revolving door and subsequently forced into an internal area, normally the reception area. By combining a Boon Edam heater with a revolving door system this cold air is negated and prevented from entering the building.

When installed, the main body of the heater unit is strategically mounted above the revolving door and using curved air outlets, creates a warm barrier around the inner opening of the doorway which counteracts any cold air infiltrating through the door.

With the option to add a Boon Edam heater either from new or as a retrofit, we can ensure that your lobby area is kept at a comfortable climate at all times whilst not impacting on the aesthetics of your entry point.

Not sure which heater to choose? At Boon Edam, we understand that our clients’ needs are as varied as they are which is why each of our heaters are created to match the curvature of each specific revolving door type. We are proud to offer a range of air curtains which can be made bespoke for all commercial, corporate or industrial requirements.

For more details on the heating solutions offered by Boon Edam, please contact the Repairs and Retrofits team on 01233 505 900 or by emailing repairs@boonedam.co.uk

Stokvis discusses the best gas-fired air heaters for large open spaces

The fully CE-approved, Stokvis Econo-Air range of gas fired air heaters encompasses both direct fired (SDF) and indirect fired (SIDF) models

The newest breed of gas-fired air heaters is designed for large open spaces such as factories, warehouses, sports halls, conference centres, exhibition halls, arenas and swimming pools. Features include fully-modulating burners which boast accurate temperature control and high efficiency, minimal or no ductwork requirement, pressurisation of space to ensure a clean atmosphere, ventilation/cooling during summer months and flexible installation options. In order to achieve the best solution for any large open space environment, careful consideration must be given to a variety of factors. After all, two spaces of identical size and shape can present very different characteristics and requirements.

Compare, for instance, an industrial warehouse where the majority of the activity involves semi-automatic fork-lifts, with an exhibition space. Factors such as occupancy and lighting levels, as well as the size and usage of the entranceways could not be more different. The specifier needs to calculate the heat load for the building accurately as well as model the circulation in what is likely to be a very tall space. Furthermore, the requirements for ventilation, and the replacement of that air, must also be considered.

Many modern factories and warehouses feature composite steel cladding panels where the insulated core cuts heat loss through the envelope to a good degree, yet warmth will still be lost through ventilation. Where extraction is part of the production process – if dust is generated or fume cupboards have to be employed – this effect will be greatly pronounced. A supply of heated replacement air is therefore required to maintain comfort levels. If it is not, the extraction system will perform inefficiently and a negative pressure may be created. This could lead to cold air being drawn in through leakage around the envelope.

For new installations, the supply of heated make up air can often provide adequate ventilation, without the need to install additional extract units. However, where additional extraction is deemed necessary, this can be integrated into the same unit to facilitate both input and exhaust flows; with the option of mechanical heat recovery from the exhaust side. The latest gas-fired air heaters can meet these combined demands economically, featuring efficiencies of 100% (based on NCV) thanks to fully modulating burners and effective intelligent controls.

The fully CE-approved, Stokvis Econo-Air range of gas fired air heaters encompasses both direct fired (SDF) and indirect fired (SIDF) models which are able to achieve these multiple objectives. A turn-down ratio of 20:1 guarantees flexible response, while output rises from 15-900 Kw for the indirect units, and 30-1200 Kw with the direct firing options.  There is also a comprehensive selection of accessories available, enabling the installation to be customised to the different requirements of the building concerned.

When heating large open areas, it is ideal to have a wide range of air distribution heads available in order to facilitate ductless distribution. This is achieved by slightly pressurising the internal space to ensure even distribution both vertically and horizontally. This avoids the need for extensive duct runs or de-stratification fans. Where the building geometry does, however, demand ductwork, then Econo-Air units can be supplied with backward or forward curved fans to overcome resistance within the runs of up to 2000 Pascals.
