The ambient networks achieving low emissions on high-rise projects

Specifying heat pump technologies for residential and mixed-used developments can reduce heat loss by up to 90 per cent compared with traditional high-temperature systems

Heating and hot water generation in UK homes are responsible for 31 per cent of the nation's carbon emissions. To achieve the 2050 UK net zero carbon target, these emissions will need to reduce by 95 per cent.

Alongside new legislation, the government wants the industry to achieve 600,000 heat pump installations a year by 2028.

Innovative heat pump technologies and ambient network solutions are specifically designed to resolve the challenges modern construction faces in lowering emissions. As a result, their specification for residential and mixed-use developments is likely to increase, particularly in more densely populated areas. 

Introducing the Zeroth Energy System - the first ambient system of its kind installed in the UK

The Zeroth Energy System from Glen Dimplex Heating & Ventilation is a low carbon, highly energy-efficient solution designed in collaboration with leading UK developers. 

It is a network of in-apartment water-to-water heat pumps connected to an ambient loop operating at 25°C.

What are the benefits of the Zeroth Energy System?

  • Heating and hot water or heating, cooling and hot water using the same infrastructure.
  • The freeing up of usable space in buildings thanks to the reduction in plant size and pipework.
  • Heat loss reductions of up to 90 per cent compared with traditional centralised high-temperature systems.
  • Reduction of overheating in communal spaces and more comfortable temperatures in apartments.
  • Healthier buildings and increased energy efficiency - modelling in SAP 2012 shows that, when used with an air source heat pump, the efficiency of the system can exceed 300 per cent.

What if I want to connect to a district heating network?

Connecting into a district heating network unlocks all the additional benefits such networks have to offer. It can be achieved without major alteration to the Zeroth Energy System infrastructure.

A spur is required from the network into the building plant room, connected to a plate heat exchanger to blend the temperature down to circa 25-40°C where it would be stored in a buffer. This would be blended again into the building’s ambient loop at 25°C to feed each in-apartment water-to-water heat pump.

Which construction projects are using the Zeroth Energy System?

The Zeroth Energy System has already been successfully specified and installed in developments across the UK. More than 120 projects are currently in various stages of construction or contracting.

Early feedback shows that ambient networks are a commercially viable solution that can help achieve compliance for residential and mixed-use projects while delivering high energy efficiency.
