Single Control Benefits automated room controls HVAC lights and shades bring to general contractors and building owners Paper June 2017 a typical office building HVAC lighting and shades are all separate systems with its own controls But that approach has many disadvantages hurting the appeal of space adding cost and increasing complexity Having a single and system to control those three systems brings benefits to key in the design construction and management of buildings such as healthcare facilities or educational facilities architects general consultants and building owners Those benefits begin during the phase extend through the installation of the system and continue the life of the building the past the only option for getting controls for those three systems to work was field integration Today however there a better option a single and system that controls all three elements Desigo Total Room from Siemens delivers control of HVAC lighting and shading from a system with a single device on the wall Less Costly Installation single system for controlling HVAC lights and shades brings significant bottom line to general contractors and building owners Installing three different control takes more time and raises costs In fact during the construction phase the approach triples installation costs when compared to one controls system for three according to Brian Antonsen director of major construction at McKinstry a design build operate and maintain firm just costs more because running three times as many wires Antonsen explains savings are significant to both general contractors and building owners But that the only benefit to a single control system Having a single product to control the white paper issued by Siemens Siemens 2017 All rights reserved systems also simplifies life for general contractors controls usually mean three different vendors When three are controlled by a common system and infrastructure general contractor has only one controls vendor to manage one throat to choke as the saying goes also notes that separate controls make it more get a holistic view of the system so one device that controls multiple room may be easier building owners the savings up to 35 percent by estimate can have a major impact on the overall In one case for example a tenant fitting out space that it could expand the use of shading thanks to the from installing a single system to control HVAC and shades Clutter Brings a Cleaner Look architect designing space has to meet many goals specific the project One priority is key on every project however space has to look good Separate control devices for lights and shades pose an aesthetic challenge since will have a device on the wall thermostats light switches and shading controls on wall isn good news when it comes to aesthetics a standpoint walls already are frequently places for LCD panels and branding pieces says Lindsey architect at Margulies Perruzzi an architecture and design firm multiple separate control near the entry door can lead to a cluttered wall look on the wall are only part of the problem device may need some form of labeling so building know which switch is the lighting switch versus switch operates the shading says Mackey The benefit of a single device to control HVAC lighting shades in an office is clear a cleaner look the building exterior an automatic shading system that shading controls except when a particular needs adjustments for viewing training videos for also would provide visual advantages have beautiful facades that look messy because isn being applied evenly across the fenestration Mackey shading sensors that know when could cause a problem and then lower or go up benefits everyone Building occupants don to adjust for glare and potential new tenants see an consistent exterior she points out Control Offers Operational Benefits HVAC lighting and shading systems don talk to other there no way for them to act in a synchronized Paper June 2017 And if those three systems operate without any the result can be that systems with each says Brad Cardoso principal architect and manager project development and implementation at Hobbs Brook a developer owner and manager of Class A space have the window treatments responding the brightness outside the building and then you have interior lights responding to the darkening of the room rooms are usually very bright when they getting sunlight even when the shades are down so there need for the artificial lighting to be turned on a single system to control HVAC lighting and shading bring substantial savings in construction costs compared to separate controls for all three systems the three systems can bring operational and benefits that are valuable to building owners having all the systems integrated into one system you will the advantage of your HVAC lighting and shading in sync explains George Kerns associate and project manager at Markon Solutions a firm three separate controls systems they going to work in harmony which can lead to things like inconsistent temperatures and tenant un comfort Not mention loss of efficiency and higher operating costs building controls are optimized they save energy occupant comfort and increase worker Accomplishing these three goals in buildings requires precise balancing of lighting and shading so that each responds to the actions of the other two Through the Life of the Building commercial office space is built many factors lead to and modifications inside the workplace From the owner perspective reconfiguring space in a zoned building makes changing office space to suit white paper issued by Siemens Siemens 2017 All rights reserved Paper June 2017 It Easier for Occupants to Save Energy energy compared to typical workers those who did the least would between 74 and 89 percent more than average researchers also reported studies energy savings from 5 to 30 from changes in occupant An integrated system can make easier to involve building occupants in efficiency efforts studies have suggested that can play a significant role in energy For example a recent study found that involving occupants can produce energy of up to 25 percent study by researchers from Berkeley National Laboratory in with Taiwan Industrial Technology Institute modeled occupant in the United States Researchers occupant behaviors by how could be expected to use room controls adjust HVAC occupancy lighting and controls concluded that workers who the most to save energy could save 42 percent and 50 percent of example with Total Room users are able to operate the shading and lighting systems from control units with a touch display are several methods of controlling system at the control unit or through smartphones or tablets An energy control feature detects energy consumption and it in a leaf symbol If energy is too high the leaf symbol red Simply by pushing the red the occupant can return room to its energy optimized setpoints the room to save energy and easily Room Automation single system and infrastructure that controls HVAC lights shades meets the needs of architects contractors and building owners There are two options for that goal custom integration or a single product offers prepackaged control of all three systems Desigo Room Automation from Siemens provides control of lighting and shades in one product Total Room Automation consists of programmable configurable room controllers
