Summary of the contracting process

The University of Essex, located in Colchester, is conducting a public procurement process for "T1125 - Low Temperature Hot Water (LTHW) Software Modelling at Gateway Building, Southend on Sea." Classified under the hydraulic equipment industry category, this tender aims to develop a detailed software model of the LTHW heating system to optimise energy use and reduce carbon emissions. The project, with a value of £20,000, has reached the award stage. The procurement process was initiated earlier this year, with the tender period concluding on 31st January 2025. The contract is scheduled to run from 18th March 2025 to 18th March 2026. The successful supplier is "Hydronic System Optimisation Ltd," based in London.

This tender presents significant opportunities for companies specialising in hydraulic systems, energy efficiency, and software modelling. Businesses with expertise in hydronic behaviour simulation, energy optimisation, and sustainable heating solutions will find this project particularly appealing. Large enterprises and firms with the capability to analyse and optimise heating systems, as well as to propose environmentally friendly and cost-efficient improvements, are well positioned to compete in such tenders, fostering growth and expanding their expertise in the burgeoning field of energy management.

Notice Information

Notice Title

T1125 - Low Temperature Hot Water (LTHW) Software Modelling at Gateway Building, Southend on Sea

Notice Description

The University of Essex is seeking tenders to create a detailed software model of the Gateway Buildings Low-Temperature Hot Water (LTHW) heating system, aimed at analysing system performance, identifying inefficiencies, and recommending improvements to optimise energy use and reduce carbon emissions and utility costs. The overall scope of the project is to create a model that will simulate the hydronic behaviour of the LTHW system, taking into account full hydraulic system configuration and components, control logic, variable outside temperature conditions based on localised weather data and variable building heating/cooling load (minimum resolution 1 hour). Calculation engines must account for both hydraulic behaviour and thermal energy flows at a full system level.
