Zeroth Energy System

The Zeroth Energy System has been created in order to counteract the issues caused by our transforming cities. We have utilised the vast knowledge and technology from our brand portfolio, along with input from industry-leading developers, to create this innovative HVAC solution that can achieve commercial gains, compliance and resident comfort.

What is the Zeroth Energy System?

The revolutionary Zeroth Energy System is low temperature energy network that utilises an innovative, refrigerant free, water-to-water energy loop, running at 15-25°C, providing heating, cooling and hot water to apartments through in-dwelling heat pump technology. The unique design and operating temperatures of the Zeroth Energy System allow a broader range of heating or cooling emitters to be used, compared to those incorporated in current building designs, such as fan coils for heating and cooling and underfloor heating for luxury applications. The system helps to improve energy performance whilst helping to alleviate overheating issues currently experienced with traditional communal heating designs.

The Zeroth Energy System allows for an easier transition to lower carbon technologies, delivering potential energy savings and reducing the carbon of a comparative dwelling by up to 29% when compared to today’s gas approach. This flexible system also allows for a choice of energy sources and can help to achieve up to a 50% reduction in plant room footprint, among other benefits.

What this means for you

The Zeroth Energy System has been designed to work with multiple energy sources, including gas and renewable plant rooms, to give you greater flexibility for your projects. Its innovative design allows you to use your choice of emitter, working with technologies such as under floor heating, fan coils or wet radiator systems, and able to provide comfort cooling without the cost premium of installing a separate cooling system. By treating the causes of overheating and not the symptoms, the Zeroth Energy System allows for benefits from minimising pipe insulation to providing cooling through a two-pipe system. Not only do you have a higher level of design freedom, but the reduction in plant room space also allows you to add value for your clients. This technology is your opportunity to leave your mark on London.

Developed with the industry, for the industry


"At a time when the industry is looking to go electric, it is good to see how innovation such as the Zeroth system takes full advantage of grid decarbonisation to help buildings achieve better compliance standards and improve thermal comfort."

- Michael Lim, AECOM


R&D initiatives are co-funded by the European Regional Development Fund and Enterprise Ireland under the Border, Midland and Western Regional Operational Programme 2014-2020.


The Zeroth Energy system is a product solution aimed at delivering reversible heat pump technology and other compatible accessories including fan coils, MVHR and smartrads into high density residential and commercial buildings.
