Priority Sites said 30,000 sq ft is under offer at Vesty Business Park in Sefton ahead of completion in June.
The 155,000 sq ft park on Bridle Road is made up of 17 industrial and four hybrid office/industrial units.
A wind turbine was installed on the site this week which will provide 10% of the development's energy supply.
Later this year, Priority Sites will start work on an £11m, 80,000 sq ft 'green' office development, Senate Business Park, also on Bridle Road. Along with other energy efficient design, the scheme will incorporate 10% on site renewable energy through the use of ground source heat pumps.

Joint letting agents on Vesty are Hitchcock Wright & Partners and CB Richard Ellis. Rents are £4.65/sq ft to £5.50/sq ft for industrial, £8.75/sq ft for the hybrid units. Purchase prices range from £225,000 to £1.946m.
