Colt’s systems can dramatically improve the buildings working environment, its façade and the external aesthetic, and at the same time, save money! Over the next 20 minutes I’d like to show you how we achieve this. We’ll talk about the savings, our experience and our products. I’ve kept this presentation quite a bit shorter than your average due to the sheer volume of products and systems on offer. We can look at any questions or project specific details at the end. Let’s first look at the savings.
The obvious first saving is the reduction and control of solar heat gain, which can significantly reduce or even eliminating the need for air conditioning. External shading can reduce heat gain by up to 90% Second, optimization of daylight cuts the costs associated with artificial lighting and creates a better working environment. Our dynamic control works by following the path of the sun as it moves throughout the day, and throughout the year, and so maximising the effect of the system. It can operate anywhere on the globe, and in conjunction with its weather station, any climate or condition. The Berlaymont building, which houses the European Commission headquarters in Brussels, underwent extensive renovation in the 1990s. Its original curtain wall façade offered little protection against heat and cold, which resulted in high energy consumption and discomfort. During the course of the renovation of the original façade, Colt provided approximately 200,000 sqft of movable glass louvres which provide solar shading, natural ventilation and protection from the elements. These louvres respond to the changing weather conditions and dramatically improved the building’s energy efficiency, contributing to driving its primary energy consumption down to 218 kWh/m2, 50% lower than a standard office building.
The control has the ability to automatically switch from shading to daylight mode. On a mid summer, overcast day, the control will read the light level and switch to a position that optimizes daylight entry. When the lux level rises, the system will switch back to its shading mode, and the blades will automatically move back to a position that is perpendicular to the sun’s rays. Thirdly, product cost. Colt specializes in motorized shading. We’re in our 80th year, 40 of those in motorized shading, and 30 of those in PV. In this time we have improved, simplified and made more economic our range of motorized systems. We are able to provide motorized systems at a fraction of the cost, sometimes as low as 5% increase over static prices.
Installation cost is also a factor. In order for us to work more efficiently and economically within the USA, we have teamed up with AWV. Based in Ohio, and part of the Mestek Group, AWV’s 100 year experience in architectural solutions, combined with their in house manufacturing and painting capabilities make them the ideal, sole licensed manufacturing distributor.
We can also save money on your installation cost. We are present in 75 countries around the world, and through a large number of those, Colt installs as well, meaning we are ideally placed to not only aid your installing contractor with a quick and easy operation, but also adjust our designs to make the systems factory assembled or even unitized. This project is DOHA International Airport, Phase 3 of a 200,000sqft automated glass shading installation. Gartner wanted to make our system as “unitized as possible” to save time on site and ease installation of their curtain wall. Colt developed a bracket that could be fitted in their factory, allowing local assembly of a panel of fins, and easy “drop on” installation.
Another example, our concealed motor mullion, can have all its motorized components housed within a box. This can sometimes be as small as a 6” x 2” two part box. The system here comes pre-assembled with gear boxes, link arms and bushed factory assembled. The fins will also arrive as a unit, meaning a dramatically reduced install time. Plastic bushes and aluminum pins mean no lubrication and almost no maintenance, again making this very economic.
Finally, photo-voltaics. Colt can design and supply BIPV in the form of shading. Not only advising on the most suitable systems but also the likely yield. This is Battery Park in New York. A 320ft LEED platinum residential development. Around the plant room, Colt has provided a louver screen to generate electrical power.
Our sun tracking controls mean that by allowing the panels to rotate so they are perpendicular to the sun’s rays, we optimize performance, eliminating some of the losses achieved by static panels and indirect solar radiation.
We also use the latest 3 dimensional drawing technology to visualize and create our products, and are able to analyze and report on our proposed systems likely yield
On the north elevation, we have supplied Shadometal perforated aluminum louvers, and on the remaining 3 elevations we have provided moveable sun tracking Shadovoltaic. Laminated glass pv louvers provide just over half of the buildings 70kwp generated from PVs
Next, let’s look at the experience
As I mentioned Colt are now into their 80th year, 40 in moving shading, and operating in 75 countries word wide. Over that time, we have put in place one of the most comprehensive teams of sales, estimating, engineers and designers.
We have built our own sun path analysis programs, written our own sun path control system software and even an app, for clients to operate their shading in the most unusual ways. Lee now has the option to select about 8 different 3 and 4 letter words remotely, whenever and wherever he is. Switching from shading mode to “app” mode, then automatically back at a designated time.
Next, let’s look at the product. If you take the vast number of individual component parts Colt makes, and look at the design capability, there are infinite possibilities for shading systems. Rather than bore you with a huge database of as many combinations, I’ll take you through a small number that highlight the varying styles we offer. If there’s anything you’d like to see more of or ask about, let me know at the end. Like most sun shade companies, we make custom systems. No two buildings are ever the same, so it’s impractical to think that an off the shelf product will work on every building. Our approach is always – “how do you want it to look and what do you want it to do?” Shadoglass Shadoglass covers our glass louver systems. With a combination of 5 carrier systems, we can make either vertically or horizontally hinged or pivoted systems. Clear, coloured, fritted or with PV, these systems can be as obvious or unobtrusive as you like.
Nearly everything is possible. This client wanted to use our LS4, as in the DOHA project earlier, but wanted to turn it through 90 degrees so it stood vertically. He also wanted uneven openings, so 3 blades open parallel and one at an angle. We made this possible, and all close so they are flush.
We made this possible, and all close so they are flush.
With installations getting larger, and technologies moving on, Colt are able to provide large and more subtle installations
Some are complete facades. Some installations have been weathered, meaning now we are able to offer “operable facades” that provide great shading.
Again rear pivoting LS4 provides façade shading
And ventilation.
This is project Koenigsbau in Stuttgart. Our LS4 system which is back hinged was chosen but with a couple of additional requirements. Firstly it needed not only to shade, but ventilate and exhaust smoke as well.
Secondly, it needed to be weathered. Thirdly it needed to be curved in section. Fourth, it needed increased performance over the standard glass, with no loss of vision.
All was designed, life cycle tested and achieved using the safety glass.
One sheet of green glass on one side and on the other side a highly selective and reflective Antelio silver coating. This reduces the solar heat load by more than two thirds with, as you can see, almost no reduction in transparency or loss if visibility.
Shadovoltaic Covers glass and aluminum with PVs. Architect Arat Siegel Schust wanted to create a visually striking structure for the stadium, while making a statement about energy efficiency. Colt came up with the design of the moveable solar shading wall with photovoltaic cells.
The solar shading wall moves every half hour following the position of the sun. 18 segments of the wall contain PV toughened laminated glazing panels that can generate a power output of nearly 15 kWp.
The wall runs on a stainless steel roller system, also designed by Colt, fixed to the exterior of the building.
This is Shadometal Shadometal covers our perforated sheet metal systems. A perforated sheet is used to clad a skeletal frame to make larger and more unusual blade designs
Perforation gives even greater light penetration and visibility through the system whilst still shading the building. It’s a more common alternative to a solid aluminum blade, due to larger sizes being achieved, and still remaining “light” Cantilevered automation is also achievable, with discreet components, all coming to site partially factory assembled for easy installation.
Vertical or horizontal, all of the carrier systems can be used in both planes
It can be made for screening as well as shading. Assembling a frame of some description to allow rigidity of the sheet, gives you a large number of screen & Shading options. We can utilize perforated aluminum, zinc, copper, woven mesh, or any material we can engineer.
As with Stuttgart, the rear hinged LS4 system can also be used with Shadometal. Blades can move through 90 degrees,
closing to form a flush facade
On a more unusual note, this architect wanted to create a living building
Aluminum bands “breathe” and the building expands. Although this could be used for ventilation, this is just decorative
Laminated and standard timber can also be used, with all supplied timber from FSC certified sources
On a slightly different note, Cambridge Public Library in Massachusetts, required an interstitial venetian blind on a large scale. Colt provided a 12” wide perforated aluminum slat bind that raises, lowers and tilts.
Even terracotta can be used.
Shadotex works on a similar principle. Fabric can be tightened to or around a skeletal frame to provide larger sized fabric style shading.
Again, LS4 along with all of the carrier systems can be used with nearly all of the products
An example of the larger type of framework clad in fabric. This is something in the region of 8 ft wide and 30 feet high, motorized and automated
Slightly more unusual system, combining Shadotex, and our next product, Ellisse.
Perforated fabric, like Shadometal gives a degree of visibility through the system whilst still providing good shading.
Ellisse Probably the most exciting of our products.
It started its life as a sliding louvered screen with operable slats, and has now been developed into a fully bespoke screen system.
Sliding and rotating screens, timber, aluminum glass and pv, vertically hinged, horizontally hinged, or a combination.
All can work with our automated sun controls systems to give optimum shading and screening.
Almost any automation can be achieved, even concertina.
Traditional shutter style systems, with timber slats
To anodized aluminum punched perforation
Colt systems can be merged into or become the façade.
This whole façade was design, supplied and installed by Colt
To demonstrate the control, the system is positioned in the open setting, whilst out of the direct radiation
As this changes the control adjust the systems
Until you’re left with closed and fully shading. The punches can be adjusted to suit more of less light entry/shade
Like the Shadometal & Shadotex, Ellisse systems can be combined.
A Shadometal style Ellisse screen can slide or fold into a closed position. At present we have just finished a prototype vertical screen system allows sets of 2’ x 8’ blades to rotate and then retract. This is about to start lifecycle testing, two project in Singapore and South America
And finally mixing 4. This is glass, shadometal and shadovoltaic and Ellisse
Any number of perforated/punched styles can be achieved
All with neat mechanisms
To give discreet shading or screening systems
And there you have it. Just a brief overview of some the types of systems we can make. The main thing to bear in mind is that we can nearly always build exactly what you want, you are not governed by just the systems you see here. In summary, Colt have moved on along way since static aluminum shading. We have more installations and systems than any other shading contractor and can offer the most detailed back up to our proposals. Colt’s can dramatically improve your buildings working environment, its façade and the external aesthetic, and at the same time, save money
