Breathing Fresh Air into HVAC Thinking London’s prestige business centre, More London, is notable not only for its striking architecture but also for its forward thinking in delivering efficiencies in HVAC from the earliest stages of building. Upwards of 125 inverter drives from Alldales Drive Systems have been installed, the majority being pre-fitted within air handling and packaged plantrooms, in three of the largest commercial buildings on site. The result is proving to be a faster commissioning overall, with significant energy efficiencies expected in use. Adjacent to Tower Bridge, More London lies at the heart of the capital’s new business development area. A former brownfield site with connections dating back to Roman times, More London is an extensive development, comprising the GLA’s city headquarters and commercial offices as well an hotel, shops cafes, bars and restaurants, expected to provide work and leisure amenities for 12-15,000 people. Alldales was commissioned to supply the inverter drives for 1 More London Place and 2 More London Riverside. 1 More London Place, now fully occupied by global business advisers Ernst & Young comprises 2 buildings totalling 380,000 square feet (nett lettable), joined by an atrium. 2 More London Riverside is a standalone building offering some 160,000 square feet of net lettable space, designated in the main for office use with some allowance for retail units on the ground floor. Air delivery and control within the two buildings is provided by six main air handling units situated on the roof, backed up by additional plant provision serving plantrooms, storage areas and a car park at lower ground floor level. For Roger Preston & Partnership, adopting a design to integrate the inverter drives with the air handling units was a logical move, as Keith Headington explains: “We wanted to move away from the practice of having plant sitting in a dedicated plant room, with centralised motor control panels. The capability of Alldales Drive Systems to be integrated within the air handling units and packaged plantrooms themselves has saved space and provides more information through an integrated serial communications link to the BMS system. This has been achieved by fitting a LonWorks card to the Alldales inverter drive rather than hardwiring the controls. Interrogation via the BMS screen allows the building users to view graphics and other information eg pump running times, power usage and consumption to assist with energy management.” Another considerable plus was the time saved in the shell and core works. The inverter drives were fitted to the air handling units off-site at the manufacturer’s premises. Basic airflow and leakage tests were carried out together with validation and testing of the plant controls, resulting in the units being delivered to site fully assembled and already partially commissioned. More London is one of a number of new developments in London where Alldales inverter drives have been fitted. Other sites include the nearby business community at Canary Wharf, where integrating the inverter drives with air handling units has also proved successful.
