Sheffield Winter Garden

Sheffield Winter Garden in the city of Sheffield in South Yorkshire is one of the largest temperate glasshouses to be built in the UK during the last hundred years, and the largest urban glasshouse anywhere in Europe. It is home to more than 2,000 plants from all around the world. It was officially opened by Queen Elizabeth II on 22 May 2003.

Part of the £120 million Heart of the City regeneration project that has created the Peace Gardens and the £15 million Millennium Galleries, the Winter Garden was designed by Pringle Richards Sharratt Architects and Buro Happold and is some 70 metres (77 yd) long and 21 metres (23 yd) high.

The building has background frost protection to a minimum of 4 degrees Celsius and it is one of the largest Glued Laminated Timber or "Glulam" buildings in the UK (Glulam is made by forming and gluing strips of timber into specific shapes). The wood used is Larch, a durable timber which will, over time, turn a light silvery grey colour. The larch, derived from sustainable forests, requires no preservatives or coatings. This reduces the use of solvents and also avoids the use of chemicals that could harm the plants. It has an intelligent Building Management System which controls fans and vents to make sure the plants are cooled in summer and kept warm in winter. The system will "learn" year by year.

The bedding plants are changed five times a year, to give a seasonal change, and all the plants are watered by hose or by watering can, as it is the only way to ensure that all the plants get the correct amount of water.

Catenary

In physics and geometry, a catenary (US: , UK: ) is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends.

The catenary curve has a U-like shape, superficially similar in appearance to a parabolic arch, but it is not a parabola.

The curve appears in the design of certain types of arches and as a cross section of the catenoid—the shape assumed by a soap film bounded by two parallel circular rings.

The catenary is also called the alysoid, chainette, or, particularly in the materials sciences, funicular.Mathematically, the catenary curve is the graph of the hyperbolic cosine function. The surface of revolution of the catenary curve, the catenoid, is a minimal surface, specifically a minimal surface of revolution. A hanging chain will assume a shape of least potential energy which is a catenary. The mathematical properties of the catenary curve were first studied by Robert Hooke in the 1670s, and its equation was derived by Leibniz, Huygens and Johann Bernoulli in 1691.

Catenaries and related curves are used in architecture and engineering, in the design of bridges and arches, so that forces do not result in bending moments. In the offshore oil and gas industry, "catenary" refers to a steel catenary riser, a pipeline suspended between a production platform and the seabed that adopts an approximate catenary shape.

In optics and electromagnetics, the hyperbolic cosine and sine functions are basic solutions to Maxwell's equations. The symmetric modes consisting of two evanescent waves would form a catenary shape.

Glued laminated timber

Glued laminated timber, also called glulam, is a type of structural engineered wood product constituted by layers of dimensional lumber bonded together with durable, moisture-resistant structural adhesives. In North America, the material providing the laminations is termed laminating stock or lamstock.

By laminating a number of smaller pieces of lumber, a single large, strong, structural member is manufactured from smaller pieces. These structural members are used as vertical columns, horizontal beams, and arches. Glulam is readily produced in curved shapes and is available in a range of species and appearances. Connections are usually made with bolts or steel dowels and steel plates.

Glulam optimizes the structural values of wood, which is a renewable resource. Because of their composition, large glulam members can be manufactured from a variety of smaller trees harvested from second-growth forests and plantations.

Glulam provides the strength and versatility of large wood members without relying on the oldgrowth-dependent, solid-sawn timbers.

As with other engineered wood products, it reduces the overall amount of wood used when compared to solid-sawn timbers by diminishing the negative impact of knots and other small defects in each component board.

Glulam has much lower embodied energy than reinforced concrete and steel, although it entails more embodied energy than solid timber. However, the laminating process allows the timber to be used for much longer spans, heavier loads, and more complex shapes than reinforced concrete or steel. Glulam is one tenth the weight of steel and one sixth the weight of concrete; the embodied energy to produce it is one sixth of that for a comparable strength of steel. Glulam can be manufactured to a variety of shapes, so it offers architects artistic freedom without sacrificing structural requirements.

The high strength and stiffness of laminated timbers enable glulam beams and arches to span large distances without intermediate columns, allowing more design flexibility than with traditional timber construction. The size is limited only by transportation and handling constraints.

Millennium Commission

The Millennium Commission, a United Kingdom public body, was set up to celebrate the turn of the millennium. It used funding raised through the UK National Lottery to assist communities in marking the close of the second millennium and celebrating the start of the third. The body was wound up in 2006.

Millennium Gallery

The Millennium Gallery is an art gallery and museum in the centre of Sheffield, England. Opened in April 2001 as part of Sheffield's Heart of the City project, it is located in the city centre close to the mainline station, the Central Library and Graves Art Gallery, Sheffield Hallam University, and Sheffield Theatres. Designed by architects Pringle Richards Sharratt, the building is primarily made from concrete and glass, with a series of galleries extending from a central avenue, which connects Arundel Gate with Sheffield Winter Garden. In 2011, the gallery was listed as the 15th most-visited free attraction in the country by Visit England. It is managed by Museums Sheffield.

The gallery has two permanent collections, two temporary exhibition spaces, space for corporate events and weddings, and a cafe and shop.

Sheffield

Sheffield is a city and metropolitan borough in South Yorkshire, England. Historically part of the West Riding of Yorkshire, its name derives from the River Sheaf, which runs through the city. With some of its southern suburbs annexed from Derbyshire, the city has grown from its largely industrial roots to encompass a wider economic base. The population of the City of Sheffield is 577,800 (mid-2017 est.) and it is one of the eight largest regional English cities that make up the Core Cities Group. Sheffield is the third-largest English district by population. The metropolitan population of Sheffield is 1,569,000.The city is in the eastern foothills of the Pennines, and the valleys of the River Don and its four tributaries, the Loxley, the Porter Brook, the Rivelin and the Sheaf. Sixty-one per cent of Sheffield's entire area is green space, and a third of the city lies within the Peak District national park. There are more than 250 parks, woodlands and gardens in the city, which is estimated to contain around 4.5 million trees.Sheffield played a crucial role in the Industrial Revolution, with many significant inventions and technologies developed in the city. In the 19th century, the city saw a huge expansion of its traditional cutlery trade, when stainless steel and crucible steel were developed locally, fuelling an almost tenfold increase in the population. Sheffield received its municipal charter in 1843, becoming the City of Sheffield in 1893. International competition in iron and steel caused a decline in these industries in the 1970s and 1980s, coinciding with the collapse of coal mining in the area.

The 21st century has seen extensive redevelopment in Sheffield, along with other British cities. Sheffield's gross value added (GVA) has increased by 60% since 1997, standing at £9.2 billion in 2007. The economy has experienced steady growth averaging around 5% annually, greater than that of the broader region of Yorkshire and the Humber.The city has a long sporting heritage, and is home to the world's oldest football club, Sheffield F.C. Games between the two professional clubs, Sheffield United and Sheffield Wednesday, are known as the Steel City derby. The city is also home to the World Snooker Championship and the Sheffield Steelers, the UK's first professional ice hockey team.
