Slowly, the term ‘Smart Building’ is gaining acceptance in the UK as concern over climbing energy costs and interest in greener buildings grows. Its a no brainer really, Smart Buildings that feature cutting-edge intelligent technology improve operating efficiencies and expenses, boast happier tenants and lower energy bills than other properties without them. While it doesn’t take a high IQ to grasp the benefits, believe it or not many short-sighted UK developers have yet to jump on the already rolling Smart Building bandwagon.

With Smart Building Technology, a Facilities Manager can log in remotely to flip the switch on more than 500 lights. In toilets throughout a 7-acre development, the toilet paper, paper towels and hand-soap dispensers can automatically tell the Facilities Manager when a dispenser is empty. Toilets can even send signals when they’re blocked. And you do tend to find that the toilets are one of the top complaints in commercial buildings, while most other tenant gripes center on heating and cooling systems, which can all be built into the smart network. Why would you want to create more problems for yourself when a Smart Building can solve them for you?

You can offer telephone, data, Internet, security and music services through a single fiber-optic network. The Facilities Manager can monitor heating, cooling, lighting, and digital signage through that same network, which currently links all retail tenants, outdoor spaces and property management offices. However, its estimated that less than 10% of new and existing commercial buildings actually contain intelligent smart building technology. Most active in the intelligent Smart Building Technology field are data centers, hospitals and universities.  A key driver of intelligent technology in the commercial real estate sector is escalating energy costs. If an intelligent lighting and energy management system is integrated into a building’s overall operating network, the owner can reap energy savings of 30% to 45% vs. a stand-alone lighting and energy management systems. A full-fledged intelligent technology system can deliver bottom-line rewards its as simple as that.

One reason Smart Buildings have yet to make it to the mainstream is that many commercial property developers in the UK have a bad habit of promoting a building’s short-term profitability rather than its long-term operating costs (although to fair they are slowly coming around to our way of thinking). They don’t usually worry to much about the buildings operating costs five years down the line because they’re not going to own it. If tenants demanded intelligent Smart Building Technology, then the developers have to deliver. But do the The tenants really understand it, do they give it much credence? As an industry I don’t think we have done enough in terms of teaching building developers, owners and designers about the value of intelligent Smart Building Technology. However, despite this slow adoption, we’ve got to be optimistic about the future of intelligent Smart Building Technology as we’ve started seeing some real growth in the last few years!

Smart building technology is not only saving building owners and their tenants cold hard cash, it is also offering significant assistance in saving this little planet of ours. Thanks in part to internet protocol-based networks, these new digital technologies are ready to make dramatic contributions in how buildings function, particularly by helping to significantly reduce their energy consumption. At Ivory Egg, we like to think of ourselves at the forefront of this revolution, so we’ve rounded up a few of our favorite technological advancements that we know will have a big impact on smart  building technology in the future:

  • Facilities Management Tools will start to use Augmented Reality & 3D
    Operating a high performance building will require high performance tools. Think 3D, augmented reality and BIM. Building Information Modeling is primarily used for design, construction and pre-fabrication of assemblies. Its benefits during this stage of building are improved design, design coordination and collusion detection. Its benefit for building operation has primarily been the extraction of data from the design and construction phases into a facility management system. In 2010 expect facility management systems to incorporate 3D BIM-like aspects to allow facility managers to visualize and understand the complex interactions within their buildings. In addition, we’ll start to see the use of augmented reality. If you watched a Premiership game with Andy Gray where the run of a player is highlighted on the pitch, or where the direction of the ball is outlined from a free kick, then you’ve seen the reality (the football pitch) augmented with the virtual, done in real-time and 3D. Imagine 3D models of mechanical and electrical systems augmented with real time data and you start to have tools to really manage high performance buildings.
  • Micro Energy Management Systems
    We tend to think of energy management systems as large enterprise-wide systems. We can expect energy management systems to evolve for individuals or specific spaces or functions. Individuals will have an energy management system on their laptops and calculate their carbon footprint at their desk. By 2011 we can expect PC software manufacturers to start offering middleware applications to allow users to monitor and manage their localized energy systems, such as plugloads, lighting and thermal comfort.
  • The Smart Grid will redefine Home Automation & Media Centers
    It is one thing to have a home automation system turn your lights off and on or a home media system which allows access to 200 high definition channels but the smart grid changes all that. The home automation system now has to communicate with the utility grid. The telecom service provider to the home is no longer the only utility supplying content and communication to the home. In fact, the media center is one of the larger energy users in the home and could possibly be managed by the smart grid. The smart grid forces the home automation market to re-think and re-invent residential systems, adding layers of new intelligence, communications and protocols not previously seen.
  • Facial Recognition will replace Swipe Cards & Credit Cards
    Video surveillance cameras have advanced the use of facial recognition. Admittedly, it’s difficult to pick out one face in a large crowd, such as people walking into a stadium (although it has been used to tackle hooliganism in Europe). However, on an individual basis, facial recognition is pretty good. With your face as your ID, gone will be the need for credit cards and access control cards/keys. The upside is better security. Credit cards can be stolen and access control cards can be passed from person to person, not so with your boat race.
  • Energy conservation measures will be given a value
    In order to retrofit and upgrade existing buildings to high performance buildings, owners will need to borrow money to fund the upfront capital costs. For banks and financial institutions to provide such credit they need to clearly identify their risks. Specifically, they need to know with some certainty the energy savings and payback period for each energy conservation step that the building owner undertakes; such as lighting control retrofits, mechanical systems replacements, control system upgrades etc.
  • Developers need to generate new revenue streams specifically related to energy
    Developers are always looking for ways to increase their net income and energy will become the newest opportunity. Expect developers to buy energy at wholesale rates and retail the energy to their tenants and building owners, embrace alternative energy sources and sell energy back to the grid, offer services to tenants such as energy information and management reports, generate revenues from recharging electric vehicles and provide similar services for the monitoring and management of gas and water.
  • The rise of the Green Eco Lawyer
    There was a period when around 20% of new buildings that received certification did not meet their energy performance targets. In the future I think we can expect to find that when someone buys or leases a building or building space with an energy certification based on energy performance and the building or space does not perform, tenants and owners will then sue. Damages may be the projected increases in energy costs over the life of the building, lack of thermal comfort, inadequate lighting staining the eyes etc. Architects, MEP firms, developers, facility managers, facility technicians, building owners, contractors and property managers may all be potential targets. I give you the rise of the ‘Green Eco Lawyer”.

 

When a leading manufacturer of electronic circuit boards in the West Midlands needed to reduce their excessive gas consumption, they turned to the Synetica DataStream Energy Monitor – an Internet connected device that enabled them to collect, store and transmit data for total energy management.  Located in open plan and modern industrial premises, the companies heating bill appeared incredibly high in relation to the size of the unit and management were also implementing a drive to reduce their carbon footprint.  The DataStream Energy Monitor would give them the real-time data they needed to see why so much gas was being used and when, with a view to heating the factory more economically.

Using the DataStream Energy Monitor, readings were taken from the Gas and Electricity meters using a combination of the built-in pulse inputs and the Synetica Wi-CT – an EnOcean based wireless current meter.  The resulting values were logged into the battery-backed memory on the DataStream and the resultant files automatically forwarded, over the companies IT network, to a PC in the Facilities Manager’s office.  Along with additional readings via EnOcean wireless temperature sensors, located inside and outside the building, it was possible to correlate the energy usage against outdoor air temperature and the activity of the heating system.

Using the DataStream’s inbuilt web interface, external energy consultants were able to analyse the data and determine that the Gas heaters were firing up 2 hours before the first occupant arrived in the morning.  The Facilities Manager immediately checked the time clock controls and discovered that the Optimum Start/Stop was not functioning correctly. Within a couple of minutes the settings were restored to their correct levels and the heating subsequently came on only 30 mins before occupancy and shut down 45 mins before the end of the working day, without any of the employees reporting any reduction in comfort levels.  This simple adjustment to the heating system achieved an overall reduction in gas consumption of 15%.

Through the use of the EnOcean temperature data, it also became evident that the heating was running unnecessarily when the external air temperature was high.  So by utilising the digital outputs of the DataStream, an interlock was set to disable the heating when the external temperature was above 18°C.  Furthermore, using the internal EnOcean temperature sensor chart from the DataStream, there were prolonged periods where the internal temperature dropped suddenly, even though the heating was enabled.  After questioning employees, it become evident that a vehicle access door was being opened to let some cool air in when the unit became too hot, an obvious waste of energy.  To resolve the problem, the manager installed an EnOcean door contact on the vehicle access door and interlocked it to the heating output.  The combined reduction in energy from these simple measures was a further saving of 20%, showing a payback on the initial install costs of less than 8 months.

Due to the built-in functions of the DataStream, the Facilities Manager was able to add and commission the EnOcean devices with minimal support from Synetica, eliminating virtually all installation costs.  The DataStream has been designed for simplicity of installation/operation and a single configuration file, which can be updated via the IP network, sets all of the required parameters including IP network settings, meter scaling parameters, alarm thresholds and EnOcean device parameters.  The DataStream was remotely pre-configured and sent to site for rapid ‘plug & play’ installation by the on-site maintenance team.  The successful installation was remotely verified by Synetica technicians, which dramatically reduced the total cost of deployment.  Upgrades to the DataStream or the addition of new meters/sensors can also be carried out remotely via the IP network in order to future proof both the device and installation.
