Mechanical engineers increasingly focused on sustainable design: survey

Two-thirds of mechanical engineers have worked on designing sustainable products, according to the first annual sustainable design-trend watch survey jointly commissioned by the American Society of Mechanical Engineers (ASME) and Autodesk.
A key trend highlighted by the survey is that more than half of the practicing engineers responding reported they expect to increase their use of sustainable design practices in the next year. Primary design concerns focused on using less energy, reducing emissions and complying with environmental and regulatory standards.
Additionally, a separate survey of ASME student members found that half of the respondents have encountered sustainable design practices in their studies and are extremely interested in green and sustainable information and causes.
The survey of ASME members is the first research conducted to understand the factors and impacts of sustainable design on mechanical engineers and their manufacturing businesses in industries including automotive and transportation, industrial machinery, consumer products and energy. Sustainable engineering refers to the design and manufacture of an ever-increasing volume of goods and services while using the earth’s resources more efficiently and producing less waste.
"Engineers have to understand the impact of their decisions on built and natural systems," said ASME executive director Thomas Loughlin. "They must be skillful at collaborating closely with colleagues in an increasingly interdisciplinary work environment to meet efficiency and resources goals impacting our only Earth."
"ASME is committed to being a strong player in the important discussion among engineers, legislators, and industry — including suppliers like Autodesk — to ensure that everyone is pointing in the same direction when it comes to sustainable engineering practices," Loughlin added.
"A few years ago our industry may have not been as focused on sustainable design, but these results confirm that designing with sustainability in mind is now a primary aim of mechanical engineers," said Robert Kross, senior vice president, Manufacturing Industry Group at Autodesk. "Autodesk is pleased to join with ASME to highlight the importance of making smarter, more sustainable design decisions."
Priorities trending toward renewable materials
Along with creating designs that use less energy, reduce emissions and comply with regulatory standards, respondents also indicated that design priorities include using renewable, recyclable and recycled materials, reducing material waste in manufacturing and improving manufacturing processes to use fewer resources.
However, cost is a major consideration when deciding to factor sustainability into developing a new product, according to the survey. One-third of the professional engineer respondents indicated that they would consider sustainable technologies for new products only if they are cost-competitive.

Methodology and demographics
The online survey of 50,000 ASME professionals and 18,000 ASME student members was conducted over a two-week period in December 2008. The questionnaire covered 16 questions and generated nearly 3,500 respondents in the U.S. Approximately 60 percent of the practicing engineers responding to the survey have careers spanning more than 20 years, with more than 25 percent focusing on the design and development of products, systems or equipment. Nearly 20 percent of the respondents work in the energy and power industry, and more than 10 percent, respectively, work in professional services and in manufacturing fields.
