Innovative Energy Strategy
The simple form of the building has been designed hand-in hand with an innovative energy strategy projecting towards the future of a rapidly de-carbonising grid.
As stated clearly earlier in the document and as shown in the energy and emissions report, this project aims to dramatically reduce embodied carbon impacts at each life-cycle stage.
The project also boasts incredible fabric efficiency which means that the building’s impact is kept as low as possible. This allows for very low-embodied carbon technology to play a significant role in maintaining thermal comfort and fantastic air quality, without huge financial inputs. This project is not suggesting a raft of complex technologies (hardware), where often heat pumps, boilers, batteries etc. need to be significantly over-sized (at a huge embodied carbon cost) to cope with the peaks and troughs of the external climate. Instead we are focussing on a simple software driven occupant focussed energy system called Atamate.
Reduce energy use and emissions from buildings through environmental control of building services. To reduce emissions, Atamate controls buildings using occupancy and zonal control, prioritising any available renewable technologies.
Improvements in building fabric and regulations covering airtightness have meant that space heating requirements for new build homes are minimal. In low energy buildings, provision of hot water typically uses more energy than heating. This airtight construction – which greatly reduces heat losses through building fabric – then leads to issues with indoor air quality (IAQ). Adequate background ventilation is required to ensure the occupant’s comfort.
With better build quality comes an increased risk of overheating. Regulations to reduce this increasing problem are likely to be included in UK building regulations in the near future as TM59 standards become statutory.
CLEAN AIR STOVE SPECIFICATION
A very small specialist stove by Termatech (TT21 ) has been specified for the main space which is one of the first stoves to have the new ClearSkies mark. This stove will produce additional radiant heat in the coldest winter months. In a very efficient building like this, many primary heating systems would struggle to adjust to the additional heat load of a stove without manual over-rides, however given that the Atamate system is based on real-time thermal feedback, the system will rapidly adjust to the occasional use of this small wood-burning stove.
