Low carbon homes​

 

Sustainability is no longer a 'nice to have', it's a must. Luckily, we've been building low carbon homes since Facit Homes was founded in 2007. Sustainable and energy efficient by design, we deliver homes that are fit for the future. Homes that use as little energy as possible from start to finish.

ECO HOMES

Sustainable by design

 

Our mission is to build a better future, one home at a time. Exceptional environmental performance is part and parcel of a Facit Home and delivering an eco-friendly construction service is a key part of our strategy. It means that we can build eco homes for every customer - not just those willing to spend more to get one.

SUPERSTRUCTURE

Sustainable timber

 

Did you know that global CO2 emissions could be reduced by 31% if builders used wood instead of steel and concrete?

 

Our timber superstructure, the Facit Chassis™, is digitally manufactured from high quality, FSC timber and engineered to meet the highest structural standards. It is robust, solid and requires zero maintenance. Timber stores carbon so, as a construction material, it reduces the carbon footprint of the build and the home itself becomes a carbon sink.

Depending on the quantity, concrete and steel can have a beneficial impact. We get the most out of these materials when we do use them. For example, our super-insulated raft foundation has a thin 100mm concrete slab which works as the structure and thermal mass as well as containing the underfloor heating system. Another material might require much larger quantities and carry more risk.

PASSIVHAUS ENERGY EFFICIENCY

High performance envelope​

Each Facit Home has a building envelope designed to conserve the heat, reducing the amount of energy that needs to be generated. It has an airtightness rating of 1.5 air changes per metre. Traditional building regulations are 3-5. This passive approach to energy efficiency depends on a super airtight and super insulated envelope that uses a combination of solar gain and solar shading to naturally heat the home. Stack ventilation and MVHR are designed bring in fresh air.

RENEWABLE ENERGY

Self sufficient homes

 

Future-proofing a home is not just about the high performance envelope, it also requires the installation of renewable energy technology. Solar panels and air source (or ground source) heat pumps have enormous environmental benefits but a slightly higher upfront cost. Ultimately the decision is out of our hands, and firmly in yours.

 

With the development of battery technology for renewable energy, the rising prices of gas and the lower costs of renewable tech, it's never been a better time to invest in the future. If you can generate your own energy, you can create a self sufficient home with net zero carbon emissions.

CONSTRUCTION

Embodied energy

 

Embodied energy is the total energy required to make or build something. It is the carbon footprint of a product or project and is often used to describe the carbon cost of construction. We keep our embodied energy low by reducing the large machinery required on site, working with sustainable timber and manufacturing each home on demand (as opposed to operating a factory). 

Our decision not to pursue Passivhaus levels of energy efficiency was due to research we conducted in 2010. We compared the cost of embodied energy required to build a Passivhaus with the reduction in operational energy that would result from it. We found that it would take each home an additional 100 years to recoup the extra embodied energy.

REDUCE WASTE

Minimise the impact

 

Reducing waste in the use or manufacture of products is a key part of low carbon construction. Blown insulation is a great example. Easy to install, it fills our timber components completely without needing to be cut to size, which would create waste in offcuts. Digitally manufacturing plywood also allows us to programme the CNC router to cut as many components from one sheet as possible, automating the cutting pattern to reduce waste.
