As a not – for-prof it organisation with 700 members, it enables creative research and “innovative testing for all aspects of building services. Many people don’t know what building services are. BSRIA says they are the parts of the building that you don’t usually see but they are the parts that make the building possible to use; things like heating, ventilation, air-conditioning, lighting and many, many more. It’s a place where the practical application of science reigns supreme and it attracts scientists, engineers and technicians from all associated disciplines to work within its laboratories and workshops. BSRIA aims to ‘make buildings better’ and without engineers of all sorts this just wouldn’t be possible. But it’s not just us that needs talented people and it’s not just engineers. The construction industry turns over around £90bn each year and that work goes through thousands of small and large businesses. The opportunities for a great career in the industry are without parallel, and “ ready for you to explore. sixty years of engineeringof sixtyyears This year BSRIA is celebrating our 60th “birthday”, so we wanted to do something a bit different. To commemorate the occasion we’ve chosen 60 notable engineers, both past and present, to show you what you could achieve as an engineer today, and inspire the next generation.

He contributed many ideas and principles which have shaped the modern world, not least of which, was his “Archimedes Screw”. This consists of a helical f lat surface screw around a shaft, which can be used to lift f luids, or propel objects through them when rotated. He also invented compound pulley systems, now commonly referred to as block and tackle, in order to lift great weights with reduced effort. These systems are still commonplace today. 05 INSPIRE prep for Artwork.indd 5 15/10/2015 17:44:07 06 Imhotep c . 2650 - 2600 BC Considered to be the earliest known architect and engineer. Designer and overseer of the construction of the Pyramid of Djoser. This was one of, if not the f irst building to be made entirely of stone and speculated to be the f irst to use columns in construction.

First to create a refracting telescope. thomas savery c . 1650 - 1715 British inventor and engineer. Creator of the f irst commercially produced and used steam engine. He patented the engine in 1699, but the patent contained no pictures. The machine was f inally revealed to the public in 1702. 07 INSPIRE prep for Artwork.indd 7 15/10/2015 17:44:08 08 1452 - 1519 leonardo da vinci sixty years of engineeringof sixtyyears Leonardo da Vinci is best known for his world famous artworks, but what many people don’t know is that he was actually an inventor and engineer. Whilst many of his inventions were incredibly far fetched and completely impractical, many of them were perfectly capable of performing their desired function. A number of his more practical designs included: hydraulic pumps, reversible crank systems and f inned mortar shells. Some of his designs, such as giant crossbows and a parachute, have actually been constructed and tested with a degree of success. INSPIRE prep for Artwork.indd 8 15/10/2015 17:44:09 daniel bernoulli 1700 - 1782 Swiss mathematician and physicist. Studied and investigated applications of mathematics and mechanics. Most famous for the Bernoulli principle of f luid dynamics. This can be used to calculate the lift force on an airfoil. sixty years of engineeringof sixtyyears James brindley 1716 - 1772 British civil engineer. First to implement canal systems in the UK. Brindley minimised excavation by using contouring. In one instance, one of the canals was carried at an elevation of 13m. james watt 1736 - 1819 British mechanical engineer who specialised in steam engines. He realised steam engines wasted energy by cooling and reheating. He adapted the design and later managed to produce rotary motion. The unit of power, the watt, was named after him. 09 INSPIRE prep for Artwork.indd 9 15/10/2015 17:44:10 10 Joseph bramah 1748 - 1814 British engineer credited with the invention of the hydraulic press.

    Oral History of Martin Cooper Interviewed by: Sean Maloney Recorded: May 2, 2008 Mountain View, California CHM Reference number: X4602.2008 © 2008 Computer History Museum Oral History of Martin Cooper Sean Maloney: [This is an interview with Martin Cooper conducted at the Computer History Museum on May 2, 2008.] So what were your earliest memories of Chicago? Earliest memories? Martin Cooper: I was actually born in Chicago, but my family moved back to Canada, which was where they had come from, when I was only a year old. So my earliest memories really are in Winnipeg. And amazingly enough my earliest memories are technological memories. Watching some older kids with a magnifying glass burning paper and desperately wanting to do that myself and I couldn't understand why when I took a broken bottle and used the base of the bottle, I couldn't get this thing to focus and burn the sun. So, it's those kinds of things; I was always curious about those things; trying to build stuff. Mostly unsuccessfully. Maloney: Did you have brothers and sisters? Cooper: Yeah, I have a younger brother. My younger brother is, or was a banker, and a musician. Both of them, very, very successfully. Maloney: Do you think your parents in any way encouraged you to get in what I guess later you’d call technology? Cooper: No. not at all. But what my parents did was encourage me to read and I've always been just an avid reader, and actually my interest in technology really came out of just being imaginative.

Fisette4 ABSTRACT This study examines the differences between two environmental assessment methods for the K-12 education sector: the United States Green Building Council’s (USGBC) LEED Schools Version 3.0 and the British Research Estab- lishment’s (BRE) BREEAM Education issue 2.0. Credit requirements are compared side-by-side and against recom- mendations from researchers in areas such as acoustics, lighting and indoor environment quality. Strengths in the two schemes and areas for improvement are highlighted, with acknowledgement that each scheme offers components and techniques from which the other could benefit.

    Typology for the Aesthetics and Top Design of Tall Buildings

    G.U. Journal of Science 22(4): 371-381 (2009) www.gujs.org Typology for The Aesthetics and Top Design of Tall Buildings Ayşin SEV 1♠ 1 Mimar Sinan Fine University, Faculty of Architecture, Building Technology Department, 34427 Istanbul, TURKEY Received: 16.02.2009 Revised: 11.05.2009 Accepted: 05.06.2009 ABSTRACT The morphological character and the top is the most important component of the tall building in terms of its impression in the city silhouette. Designers of attractive tall buildings, whose investors tend to create a symbolic image, mostly prefer tops with aesthetic expressions. However many tall buildings with slipshod tops create unidentified skylines as it is the case for many modern cities of today. In this paper, the particular issue of visual impact and tops of tall buildings are addressed and a historical category system of seven periods is proposed. Then each period is illustrated in a series of outline figures showing the comparative heights and profiles of leading examples within each category. As a result, it is recognized that tall building design is a holistic process, and it is impossible to consider formal and aesthetic principles in isolation without reference to technology of the era, as well as the investors’ demands. The impact of tall building tops involves a consideration of social values followed by scale and traditional design principles versus contemporary expression of architectural design objectives. Key Words : Tall buildings, skyline, skyscraper, high-rise, aesthetic, urban context. 1. INTRODUCTION footprint buildings, which are quite tall but their size / floor area rules them out as being classed as a tall The visual impact of major buildings on the city scape building.
