Appeasing the planners
We love making architects’ worlds better and got involved when Chris needed as much advice as possible on the specification to appease planners. Challenged by his need for a 10% reduction in Carbon Emissions several of our team were involved, including Jon Ponting.
On the way to helping the dwelling achieve a negative emission rate and an EPC rating of 103, we completed a SAP calculation to measure its sustainability before including renewable technology. We then carried out a feasibility check on renewables, a Code Level 6 pre-assessment and an Energy Statement.
Generating more energy than it uses each year
The original plan included intermittent extraction fans, but we advised on whole-house ventilation with heat recovery instead. Furthermore, by significantly improving the entire building envelope, using heat recovery technology, a wood pellet boiler for heating and hot water, and 150 square metres of solar PV and solar thermal panelling, everything’s set for this home to generate more energy than it uses in a typical year.
A sub-3 air test result
We’re also expecting the property to get a sub-3 air test result. All internal lighting is proposed to be low energy (exceeding the current Part L limit of 75%). And we also expect the dwelling to save more than 19,000 kg of CO2 annually compared to baseline calculations.
Describing the project, Angela Wood says: ‘It’s impressive stuff for an impressive structure. And unlike Tolkien’s works, the improvement over the current TER is anything but fiction!’
