A carbon negative house

“One cubic metre of hempcrete will sequester approximately 110kg of carbon from the atmosphere. An average sized house would be built using around 50 cubic metres of hempcrete for the walls, meaning that an average hempcrete house would lock up 5.5 tonnes of carbon for the lifetime of the building. This compares to a more standard new house of a similar size, in which the walls would be likely to emit 48 tonnes of carbon into the atmosphere (M. Berners-Lee 2010). This is a saving of 53.5 tonnes of carbon for every house built.”

“According to the 2018 Global Report released by the International Energy Agency and the United Nations, the building sector accounts for the highest energy use (36%) and emissions (39%) of all industries.“

A positive impact on your expenses

In Australia - if you plan to build a standard brick veneer home - your architect or building designer will recommend a one tonne HVAC unit for every 46.5 m2. If your house is a hemphouse, that same HVAC requirement would drop to around one tonne per 140 m2. This is a saving on heating and cooling of 68%. Calculate the difference across the lifetime of your home and the savings will be staggering.
Even the Energy consumption of Hempcrete structures is significantly lower than buildings built with Hebel Board, the most common premium ‘energy efficient’ cladding used currently in Australia.

Furthermore, Hebel board weight-for-weight has the same carbon footprint as concrete. And the dust from hebel contains crystalline silica which is harmful when inhaled.

If we can insulate our homes with a carbon based lifeform, which sequesters Co2 as it grows; why might we squander our time by producing an inferior synthetic product?

I’ve fine tuned the Hempcreting process with the leaders of industry in the UK to provide a higher standard of genuine sustainable housing right here in Australia.
