The Rookery is designed with a fabric first approach. Designing with a ‘fabric first’ approach is the most sustainable and user effective way to improve and maximise energy efficiency and reduce carbon emissions for the dwelling over its life time. It involves improving the performance of the components and materials that make up the building fabric, before considering the use of mechanical or electrical building services systems and renewable/LZC technologies.
All the fabric, window & door U Values exceed Building Regulations Standards. Accredited Construction Details have been adopted to minimise thermal bridging and air leakage. In general terms, the building envelope, floors, walls, roof and windows etc. are super insulated and well-constructed, so that it requires the smallest amount of energy to heat up, and the property retains the heat well when it does.
As the Rookery is being occupied as a holiday let, we wanted to ensure that the systems within the property were user friendly, familiar and easy to maintain. So we opted for a Highly efficient Oil Condensing combination boiler for the central heating and have incorporated a 3.6kWp PV array on the South Facing roof to generate our electric. We have included a log burner in the main living area, which also reduces the use of the oil boiler and the open plan layout means that the whole space heats up really quickly.
The Rookery relies solely on a natural ventilation strategy which means no energy is used for forced Mechanical Ventilation and a healthier environment for the building occupants. All the white goods are energy efficient (A+ or A rated) and we install 100% low energy lighting. We have also used materials with low VOC emissions.
Consideration has been given to using materials and construction specifications that have a low environmental impact, such as those achieving an A+ or A rated under BRE’s Green Guide. Where possible, materials have been chosen that are responsibly sourced (such as FSC timber), recycled or reclaimed and insulation materials have a GWP (Global Warming Potential) of 5 or less. Indoor water use is reduced by use of fittings with lower flow rates and usages.
