About Point One One project

The name for our project to build a single, energy efficient, home is derived from the design values for the building elements to achieve  0.11 W m-2 K-1 where:

 

Walls:  0.11 W m-2 K-1 compared to 0.3 in the 2010 Building Regulations.

Floors: 0.11 W m-2 K-1 compared to 0.25 in the 2010 Building Regulations.

Roof:   0.11 W m-2 K-1 compared to 0.2 in the 2010 Building Regulations.

Ecofirst Consult were engaged to carry out SAP experiments and provide a Sustainability Statement in support of the planning application, the statement concludes :-

Though the proposed development is clearly not a true zero carbon home (there is no electricity generation capacity), it does meet the currently-proposed on-site performance levels of a 2016 ‘zero’ carbon home. The current definition of a ‘zero’ carbon home is one with a heating demand  of less than 45 kWh m-2 yr-1 and an onsite emission rate of 14 kgCO2e m-2 yr-1. The planned home has a heating demand of 41.4 kWh m-2 yr-1 and an onsite emission rate of 10.58 kgCO2e m-2 yr-1, and therefore surpasses these requirements.
