Both science and technology have a fundamental relationship with design. Technology preceded science, but now most technological developments are based on scientific understanding. Traditional technology comprised useful artifacts often with little understanding of the science underpinning their production and use. In contrast, modern technology involves the application of scientific discoveries to produce useful artifacts. The application of scientific discovery to solve a problem enables designers to create new technologies and these new technologies, in turn, can impact on the rate of scientific discovery.

  • A Guide to Environmentally Sustainable Landscape Architecture Products
    A Guide to Environmentally Sustainable Landscape Architecture Products jonite.com/a-guide-to-environmentally-sustainable-and-long-lasting-landscape-architecture-products May 23, 2019 Landscape architects play an essential role in creating design interventions to ensure environmental sustainability. As we’ve explained in our other post on architectural trends that are here to stay (link), sustainability and climate adaptation strategies have not only been increasingly in the focus, but is here to stay. Sustainable architecture aims to incorporate elements of green design into various parts of the building. The main goal is to strike a beautiful harmony between green life and architecture to preserve nature and improve the quality of living. Green buildings are designed in a way to be built in a way that reduces harmful impact on the environment. What is environmentally sustainable design? 1/13 Environmentally sustainable design (or environmentally-conscious design, eco-design) is the philosophy of designing physical objects, the built environment and services to comply with the principles of ecological sustainability. Its core idea is to eliminate wastefulness and minimise environmental impact through architecture design. There are some common principles in sustainable design that most designers take into consideration when scoping out their design projects. They include the following: Choosing low-impact materials: These come in the form of choosing products that have high recycled content incorporated in the manufacturing process. Also, designers may choose materials that are locally sourced to reduce the carbon footprint of transporting materials to the project site. Choosing energy-efficient materials: Designers may also take the time to understand the material’s basic manufacturing processes and make their choice based on the energy involved in producing their selected materials.

    MCHENRY COUNTY COLLEGE ARCHITECTURAL AND ENGINEERING DESIGN TECHNOLOGY A PROGRAM IN CONJUNCTION WITH THE MCC FAST TRACK The Fast Track at McHenry County College is a cohort-based program that helps give students the advantage they need when competing for jobs in today’s workforce. Through the Fast Track, students can earn a certificate in two years or less and an associate’s degree in three years, depending on the program. Nearly everything manufactured and built in today’s society starts with computer generated drawings. Drafters and designers work in a variety of industries, including manufacturing, architecture and construction to develop the technical drawings needed for the manufacturing and construction of our built environment. Using the latest computer- aided design (CAD) systems, including parametric solid modeling and building information modeling (BIM), they create both 2-D and 3-D models and drawings for everything—from the simplest machined part of a mechanical assembly to the largest and most complex structures SALARY RANGE such as bridges and skyscrapers and everything in between. $30,000 to $45,700 The Architectural and Engineering Design Certificate program, with specialization in either architectural, engineering, or interior JOB OUTLOOK* design technology, represents a collective approach to developing Projected growth is 3-9% in most or upgrading the necessary visualization, graphical communication fields, higher in others.

  • A Critical Role for Design Technology Charles L
    Institute of Design Illinois Institute of Technology Chicago, Illinois U.S.A A Critical Role for Design Technology Charles L. Owen Distinguished Professor of Design (Keynote article, Design Management Journal, Design Technology Issue (Spring 1993): pp. 10-18) A phenomenon very apparent to the American businessman, as well as to any lay observer, is the wave of "restructuring" passing through the country. It is a fact of life for seemingly all large companies, and through ripple effects, it affects all but those companies most finely tuned to the new realities of the marketplace. Less apparent, but of greater portent, is the implicit recognition that new rules are taking form for how the games of business will be played. As the recession abates, and revitalized industries emerge, they will not return to the ways of the past; they will seek a development philosophy for their products and services in tune with the times. Of the factors involved in this product/service philosophy, design will be one of the most important, as the growing interest of the business press makes that very clear. There is little question that design will play a major role in the kind of economic world on the horizon. The question is, What role will that be? The Quality The issue really involves "quality", and what is now being termed "product Pyramid integrity". To a great extent, the present opportunity for design is what it is because of the now-general concern for quality. Most customers equate quality with craftsmanship, an observable attribute that has been drummed into everyone’s consciousness for at least a decade.

  • 244 Project 1 = 10% Sustainability 101 Design Manifesto
    244 PROJECT 1 = 10% SUSTAINABILITY 101 DESIGN MANIFESTO WHAT • Write your vision for your career through a personal manifesto. Present it in the form of an 11X17” colour poster. Use concept, layout and typography to share your vision in a unique way. • Your target audience is future industry employers. Imagine that employerw will decide who to hire based on this poster. WHY • To document your understanding of sustainable design and to explore how you see it influencing your future practice. • To practice communicating a message quickly and engagingly in a poster format, using concept, layout, imagery, typography, etc. • To give you an opportunity to implement design principles such as balance, scale, colour, figure/ground and framing. HOW • Review the links to examples of past design manifestos for inspiration. • Consider what you’ve uncovered about sustainable design. What resonates with you? What elements of sustainable design will you apply in your work? • Design a poster that includes your name and demonstrates that you understand the four pillars of sustainability. Write your manifesto in one or several paragraphs. It’s a poster, so keep it to 150 words maximum. • Consider the vernacular and the sensibilities of your target audience. • Consider what kind of design will best reflect you and your personality as a designer. • Combine two different type families in your design, and use at least three levels of type hierarchy. • Consider how to inject your personal voice into the copy itself and the typography. • Sketch different ideas. Revise and refine. • Post a jpg/png of your poster on your blog along and provide a rationale.
