Low Energy Appliances
All appliances have been carefully considered to eliminate unnecessary electrical demand and to optimize the efficiency of the essential items (cooker, fridge, low energy lighting etc). All selected components are category A* rated for maximum efficiency and minimal electrical draw when in use.
Mechanical Ventilation With Heat Recovery
For winter months when the outside air is cold relative to the required inside temperature, a whole house clean air comfort ventilation system is fitted with heat recovery (to preheat incoming cool fresh air with outgoing warm stale air) is used to reduce space heating requirement to a minimum.
Household and garden non-potable water requirements are met by collecting rainwater from the main roof via cast aluminum gutters and downpipes and storing it in water butts and a ‘Rainharvester’ underground storage tank. Water from underground storage will be filtered and used for flushing toilets and the washing machine. The water butts are used for garden irrigation. Water efficient flush toilets have been used along with air rated flow restricted taps a maximum flush of 4 litres. Water use is being monitored to ensure a non-wasteful system of use is maintained.
Healthy Internal Environment
Scatter rugs over stone tiled and waxed timber boarded floors, organic non-volatile solvent paints, avoidance of formaldehyde and other toxic equivalents combined with natural materials and summer natural ventilation and a winter heat recovery mechanical ventilation system provides a healthy internal air quality.
Kitchen waste and garden debris material is composted until dry and inert and then returned as a valuable non-toxic fertilizer to the food growing areas of the garden and greenhouse.
Organic Home Produce
The carbon footprint of most households is greatly increased by the reliance on industrial food processing systems and the food miles required to get food to our tables. The lean to greenhouse and protected walled garden to facilitate growing organic home produce on the site will go some way towards reducing the applicants’ carbon footprint over an extended time period.
