More than half have worked on designs that comply

This preview shows page 7 - 9 out of 15 pages.

two-thirds of working respondents have worked on designs that use less energy or reduce emissions. More than half have worked on designs that comply with environmental standards and regulations. The most important sustainable technologies are considered by all engineers to be designs that use less energy or reduce emissions (64% of practicing engineer respondents and 66% of engineering student respondents). The second most important sustainable technologies are viewed as manufacturing processes that use less energy and natural resources (27% of practicing engineer respondents and 43% of engineering student respondents).

In the coming year, most practicing engineers expect their organization to become more involved in sustainable and/or green design. Approximately 63% of practicing respondents expect their organization’s involvement in sustainable and/or green design to increase. Only 1% of practicing respondents expect their organization’s involvement in to decline in the coming year, while 36% expect no change. 5. Factors Influencing Sustainable Design Numerous factors influence the use of sustainable design and practices, according to practicing engineers. Many of these are listed in Table 2. Regulatory requirements are most likely to influence

Client demand was cited as the second most likely factor (by 19% of respondents as the greatest factor and by 51% as one of the top three factors). Rising energy costs was also indicated to be significant factor (with 16% of respondents considering it the greatest factor and by 53% as one of the top three factors). Table 2.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
