The Army will be buying light bulbs. Lots of them.

The Army said it will replace all incandescent lights with energy-efficient compact fluorescents over the next five years. It’s part of an energy conservation effort that includes green roofs, solar water-heating, and storm-water management.

By 2020 the Defense Department intends to reduce its energy consumption 37.5% below 2003 levels. The Army said it will raise the ante, reducing usage by 45% in the same time frame.

GSA also is upping the ante to save energy in new federal buildings. Construction projects must achieve LEED Gold certification, the second-highest rating from the U.S. Green Building Council’s Leadership in Energy and Environmental Design program. Until now the projects were required to meet LEED silver standards, the third highest.

“This new requirement is just one of the many ways we’re greening the federal real estate inventory to help deliver on President Obama’s commitment to increase sustainability and energy efficiency across government,” Robert Peck, chief of the Public Buildings Service, said in a statement.

One reason the Army could have trouble building up its acquisition workforce: It takes more than four months to hire a civilian employee.

Undersecretary Joseph Westphal said the average time to hire is 130 days; by then, many applicants have gone to work somewhere else. Westphal said the Army’s new Civilian Workforce Transformation Plan is designed to cut the time to 80 days, Government Executive magazine reported.

A former GSA executive, Roger Waldron, has been named president of the Coalition for Government Procurement, a trade association representing GSA schedule contractors.

Waldron spent more than 20 years at GSA and was a member of the Acquisition Advisory Panel, which recommended changes in how the government could more effectively procure commercial services.

He succeeds Larry Allen, who resigned.
