Each year the North American Copper in Architecture Awards acknowledges and spotlights selected North American building projects for innovative and exceptional use of architectural copper. The architectural copper awards program highlights a wide scope of projects which highlight craftsmanship, attention to detail, and architectural vision. Copper has historically long been used for its great natural beauty and finish, it's durability and performance, copper's long service life and recyclability. Copper is still today a superior building material and also one of most eco-friendly and green building materials, which is being utilized and adapted for an ever wider variety of contemporary and cutting edge building and architectural applications. Three of the twelve copper in architecture award winners are described and shown below.

The Waipolu Gallery above uses copper wall cladding and copper roofing which were chosen for this project as copper will perform well over a very long time and with very little maintenance in a very corrosive ocean side location. Copper's beauty and fluidity compliment the modern art contained within the structure. The copper provides a softer contrast to the other more linear materials used. Excellent workability or malleability of copper was advantageous allowing easy re-working or shaping on site. The building architects also like there will be changes in copper's patina or color over time, producing an ever evolving work of art. The studio with it's stainless steel, glass and concrete linear space is joined by a floating glass bridge to the copper clad gallery. The glass bridge rises above a limestone staircase which connects the building's three levels.

The Mark Olsen Project exhibits excellent old world craftsmanship, with a copper roof and other architectural copper features such as copper finials, copper gutters and ornamental downspouts with copper conductor heads, copper crown molding, fascia and soffit, copper chimney top shroud and extended copper window box. This stately home has exquisite detailing and exudes quiet elegance from it's naturally weathered copper features. 16,000 pounds worth of hand crafted architectural copper work are used for this home's architecture. The copper roof is comprised of diamond shaped interlocking copper shingles, copper ridge vents and flashing. Of note, no sealants were used, only traditional craftsmanship and installation techniques were employed along with some soldering work on the copper gutters providing very long term durability with little to no maintenance required.

One hundred fifty years in the making, the Cathedral of St. John the Baptist in Charleston, South Carolina has at long last been restored after being completely destroyed by fire in 1861. A soaring neo-gothic style copper spire, which had long been planned, was finally realized this past spring. The stunning beauty of the copper spire with it's gold leaf finished copper cross can be seen across the Charleston skyline and out to Sullivan Island. The cathedral's tower was finished with a stone veneer and at it's top there are four copper clad archways with copper torch finials. The copper spire with gold-leaf copper cross finial is perched on top at center of the copper arches. The 200 square feet of gold leaf which covers the cross will last at least 40 years without touch-up while the crowning copper art work comprised of arches, finials, spire and cross at the peak of the cathedral will last and stay beautiful for generations to come.

Historic Leader Heads - Conductor Heads - Hopper Heads

Leader heads, also known as conductor heads and hopper heads, number into the many thousands and can be seen in many countries around the world, especially throughout Europe. England has many examples of leader heads or hopper heads in many styles and several materials. Historic English leader head styles include Victorian, Edwardian and Georgian with historic leader head materials being comprised mostly of lead and cast iron. They are wonderful examples of craftsmanship. Copper leader heads found throughout much of the rest of Europe and cast aluminum leader heads are slowly replacing the old lead and cast iron English designs seen in the pictures below.

Windsor Castle (Lead) Leeds Castle (Lead) Canterbury (Cast Iron)

These examples of historic leader heads are taken from famous castles and from Canterbury all in England. Many earlier leader heads were made from lead and had intricate designs. You can see the rose of England on the Windsor Castle leader head and a swan on the Leeds Castle leader head. Later leader heads were also made of cast iron like the Victorian design shown above at Canterbury. That same Victorian design is repeated on Canterbury's downspouts and downspout brackets.

Example of historic leader head faithfully replicated using copper

Rutland's architectural craftsmen are able to take any historical leader head or architectural heritage conductor head or hopper head design and faithfully recreate it using copper or aluminum. A heavy-weight unfinished, pure copper, TIG welded copper leader head reproduction is of the highest quality, it will weather beautifully, blend in well with most historical building architecture, endure maintenance-free for many decades to come and also is an eco-friendly green choice for historical preservation or architectural restoration - renovation work.

Note:
Leader heads frequently are used as architectural features on buildings, providing both a decorative and functional purpose. Rain water collected by a rain gutter or roof scupper is fed into a leader head. Sometimes a downspout connected to a gutter system or even multiple downspouts will feed into a leader head. Downspouts, also referred to as downpipes or leaders, are the vertical pipes that carry rain water from a gutter or leader head down to the ground to drain into a water barrel, cistern, sewer or seep into the ground. Leader heads or conductor heads fed by a scupper (drain opening in a wall, parapet or edge of flat roof) are sometimes called scupper boxes. Some parts of the world also use the term rainheads when referring to leader heads or rain collection boxes. Functionally leader heads serve several purposes. Leader heads serve as a collection box for multiple gutter downspouts to empty into and funnel those into one downspout leading down to the ground. Leader heads also mix air into the conductor to help eliminate back pressure or vacuum and promote heavy rain water flow through the downspouts. Decoratively and visually, leaderheads also help break up lengths of downspout providing both architectural interest and elegance or panache. Leader heads are still specified by architects and featured by builders in modern architecture for public buildings, churches, fine custom homes and especially upscale architecture, usually pairing copper leader heads with elegant copper gutter systems. Historical leader head reproductions are very popular as are more modern designs. An assortment of sixty-seven historical and modern leader lead designs can be seen at Leader Heads- Conductor Heads by Rutland

Differences among Leader Conductor Heads

Conductor heads or leader heads as used in rain gutter systems are sometimes also called hopper heads, rainheads, scupper box, leader box or rain collector box. Conductor heads or leader heads provide both a functional and decorative feature to downspouts used in rain gutter systems and also when positioned below flat roof scuppers to collect their rain water run off. You will commonly find leader - conductor heads available in aluminum and copper material. Because they do add to the cost of a gutter system, leader heads might not be installed with cheap gutter systems or specified by some builders when cutting costs and sometimes corners can affect decisions. Functionally, conductor heads collect rain water flowing from gutter and feed it out to the downspout or downpipe below. The leader head helps alleviate any vacuum back pressure or congestion in the downspout, becoming increasingly important with each story of height a building has. Cosmetically a conductor head - leader head will enhance downspouts and gutter systems and become a visually heightened architectural feature. Proper selection of leader heads, downspouts and gutters assuredly enhance, beautify and add real value to commercial and residential property. To provide the most impact and lasting value, a leader head's style or form should be richly pleasing, they should exude or project quality and exhibit fine craftsmanship.

Some times conductor heads (leader heads) will be made more cheaply by using thinner walls and overlapping or tabbed construction employing solder and/or rivets on the seams. While cheaper, using overlapping material on the seams along with rivets, just does not offer a nicely finished, elegant appearance. Use of tabbed construction, butting material up the seams and then closing seams using solder will look better crafted than the overlapped - riveted approach, especially if the joints are tight and solder is tinted to color match the raw material. Several additional problems may eventually present themselves with any of these approaches. If seams are merely overlapped and riveted, leaks may develop as parts of the seam open up in time. Soldered seams may also crack with age, flexing and pressures. Northern climates where ice could expand inside a leader head will split the leaderhead open when a tabbed or soldered seam gives way. The same thing can happen to crimped downspouts when the seams can bulge open from ice pressure.

A more elegant, durable approach is using thicker material and TIG welding to close up any seams and then polishing the seams. This provides not only a virtually flawless appearance and obvious fine craftsmanship, but also gives leader heads lasting strength and durability, to avoid the problems mentioned above. Yes, premium TIG welded aluminum and copper leader heads with thicker walls will cost a little more than their cheaper competition but they warrant that with their more pleasing appearance, requiring typically no repairs and little to no lifetime maintenance, with markedly increased durability and longevity. Quality TIG welded leader heads genuinely provide both real and perceived value and they truly do become one of the more striking architectural features of any commercial or residential building.
