An insight into some project details

Envirotech were appointed as the main contractor to provide a turnkey solution. The project was completed over a 25 – week programme to coordinate with the university summer break, with a critical ‘heat on’ date to ensure zero disruption.

The scope included a full strip out & installation of 3 boilers, 1 new chiller, 1 CHP, all associated pipework, pumps & controls. The new Energy Centre feeds district-heating circuits to several campus buildings.

A temporary heating plant was provided from April—July & Temporary DHWS plant from July —September & all DHWS services were kept live.

The existing boosted cold water provision was replaced with a packaged booster ‘room’.

A new chilled water pumping room was created externally within a new GRP enclosure.

Thermal stores were located externally and suitably weather treated.

The system was switched from an open vented to a sealed system, & existing MCWS tanks were removed & the domestic water systems pressurized.

Project constraints

A live ‘college environment’ with operational hours 7am – 10pm, 7 days per week meant that ‘out of hours’ shutdowns were very limited, from midnight for a 6 hour maximum period!

Restricted site access required diligent planning & regular stakeholder meetings to ensure zero disruption to campus operations.

There was a requirement to work very close to existing landscaping with TPO’s, Envirotech worked closely with the university grounds team to develop a tree-root protection plan & avoid damage.

Commendation from Lee Hatton at Coventry University:

“Thank you to the entire Envirotech Group for all the hard work in completing The Energy Centre. Our first ever early completion!”
