The Zero Carbon Solution is a unique combination of technologies that, for the first time, makes it practical and affordable to achieve zero carbon status for new homes and low-rise commercial developments with appropriately engineered building fabric.
The system has been designed as an answer to the government’s 2016 zero carbon house building target.

The Zero Carbon Solution is scalable and economical, and can meet a home’s full annual heating and hot water requirements using just solar energy.

The system consists of three core components:

Advanced solar energy capture, collecting both electrical and thermal energy, using HYBRID PV-T panel arrays.

Our patented EARTH ENERGY BANK, which provides inter-seasonal energy storage within the buildings footprint.

Energy recovery using a conventional water-water heat pump, within a system that enhances it’s efficiency.

How it Works

An array of hybrid Photovoltaic Thermal (PV-T) panels, which collect both electrical and thermal energy, are installed in the roofline of the building. These are used to generate heat to warm the house and its hot water system, as well as provide electricity to run the system and for lighting.

Because solar energy is naturally in abundance when it is least required (during the long summer days), the Zero Carbon Solution utilises a patented energy storage method, the Earth Energy Bank (EEB). Heated fluid is pumped from the roof through a series of pipes underneath the house, warming the surrounding earth. This heat can then be drawn upon as required via a heat pump during the coldest weeks of the year.

A sophisticated controller manages the flow of energy within the Zero Carbon Solution. Taking into account the outside and inside temperatures, the occupants’ desired temperature, the temperature of the domestic hot water and the temperature of the EEB, whilst monitoring the energy flow from the PVT panels, the system determines the best energy source to meet demand at least cost.

When used in buildings with the appropriate building fabric, the Zero Carbon Solution can surpass both the current and known future requirements of Part L, as well as considerably exceed Code for Sustainable Homes Level 6.

The Zero Carbon Solution has been tested in the company’s demonstration home, the Solar House. It’s performance is being monitored by De Montfort University’s Institute of Energy and Sustainable Development.
