The Zeroth Energy System - An ambient heat network solution

The Zeroth Energy System

The Zeroth Energy System is a proven solution that utilises a central ambient loop to supply energy to in-apartment heat pumps. These uplift the energy from the central loop to provide space heating, domestic hot water, and cooling to residential apartments.

This market leading solution is already installed in projects in the UK, helping to reduce carbon emissions and improve the energy efficiency of new residential developments.

Design guide for the Zeroth Energy System

To ensure the efficient and cost-effective design of an ambient network solution, diversity factors need to be correctly considered when calculating the energy demands of the development.

TÜV SÜD and Wallace Whittle, in collaboration with GDHV, have compiled a design guide that assists with the correct sizing, system design and effective implementation of the Zeroth Energy System, highlighting the main considerations and calculations that need to be made.

Efficiency

The Zeroth Energy System can offer an overall system efficiency of around 300%. The cooling option, where specified, offers a space cooling efficiency ratio of up to 5:1. Its design allows for a reduction in plant and riser space requirements when compared to traditional cooling services, increasing the valuable usable footprint in a development.

|

Compliance

The Zeroth Energy System has been designed to overcome the challenges of medium and large-scale communal residential developments in the UK. It supports compliance specification under the current Building Regulations but also helps with meeting the objectives of the stricter proposals of the Future Homes Standard. The Zeroth Energy System also supports projects in meeting the expectations of The London Plan and other regional obligations.

Specification flexibility

Collaboration with leading UK developers on the Zeroth Energy System resulted in unrivalled specification flexibility that helps to overcome many of the challenges modern residential developments face. This means a greater choice of plant, distribution system, emitters, and controls, helping projects to meet their objectives from energy source through to apartment design.

Ease of application and installation

Designed and manufactured in the UK specifically for the UK market, each of the Zeroth Heat Pumps arrives on site pre-wired and pre-plumbed. The compact in-apartment heat pump and water cylinder are integrated into one unit for better handling and can fit into a standard service cupboard for easier installation and long-term maintenance.

Acoustic performance

When developing the Zeroth Energy System it was important to achieve a design that fits well into a modern home with optimum acoustic performance. The in-apartment heat pump is extremely well insulated to minimise noise, making the Zeroth Energy System the quietest solution of this kind available on the market, operating as low as 23dB.

End user comfort and control

The Zeroth Energy System offers greater comfort through a set of easy controls integrated within the unit. An in-apartment smart thermostat of the designer’s choice can be specified where enhanced thermal control for the occupier is required. The system can be easily integrated with most building management systems, offering greater design and specification choice.

The Zeroth Energy System - An ambient loop heat network solution

  • The Zeroth Energy System was designed in collaboration with leading UK developers to overcome the challenges of modern residential and mixed-use developments and deliver a solution capable of increasing energy efficiency whilst reducing the carbon footprint of our buildings.
  • The Zeroth Energy System is the only communal ambient loop solution with completed installations in the UK, demonstrating that the Zeroth Energy System can meet the challenges of tightening regulations. This also helps developers to deliver commercially viable projects that achieve maximum occupant comfort.
  • The high energy efficiency and flexibility of specification the Zeroth Energy Systems affords, from the energy source to the choice of emitters or controls, helps support projects in meeting compliance requirements. It also allows for greater freedom of specification that can help meet project specific design objectives and to set a development apart from others.
  • The familiar looking in-apartment unit is compact and relatively easy to install. Each Zeroth Heat Pump comes with a two-year warranty and a fully supported maintenance package is available that extends the warranty up to five years.
