The pace of new office construction in Prince George's County has accelerated in the past four years. Commercial office space since 1979 is expected to exceed 5 million square feet by the end of this year.

Much of that growth is concentrated in office and industrial parks. Several of those parks have been selected for special emphasis in the county's economic development program this year. Among them are:

* Capital Office Park. A 32-acre office park at Interstate 95 (Capital Beltway) and Kenilworth Avenue in Greenbelt. Three of four planned eight-story office buildings have been completed. Construction is to begin soon on a 17-story Hilton Hotel.

* Plaza Towers North. A 30-acre development at Powder Mill Road and I95 in Calverton. Proposed development includes an office park containing up to 600,000 square feet of commercial space and a hotel/conference center.

* Maryland Trade Center. Baltimore-Washington Parkway at beltway interchange. Developers have completed the first of three 16-story office towers. A 200-room hotel and banquet/conference center accommodating up to 2,000 persons is also planned. The 34-acre site also includes a 265,000 square-foot shopping center and eight restaurants.

* Greenbelt Triangle. Greenbelt Road, near beltway. Plans call for development of office park, major hotel and other commercial uses on 42 acres.

* Metro East. Adjacent to Metro and Amtrak stations at Interstate 95 and U.S. Rte. 50 in New Carrollton. Completed facilities at 73-acre project include eight office buildings. Nearing completion is Metroplex 2, a futuristic 12-story office tower.

* Washington Business Park. A 235-acre campus at Maryland Rtes. 704 and 450, near the beltway. Current development includes 21 industrial/office buildings containing more than 1 million square feet.

* Inglewood Business Center. Maryland Rte. 202 at the beltway and near the Capital Centre. Office buildings and hotel/convention center are planned for the 230-acre site.

* Maryland Science and Technology Center. Maryland Rtes. 50 and 3 in the Bowie-Collington area. Proposed for development on 463 acres is a high-technology employment center modeled after the Stanford Research Park at Palo Alto, Calif., the Princeton University Forrestal Center and the Research Triangle at Raleigh-Durham, N.C.
