So at the moment our�the thing we are really focusing on will be on insulation.\" \u003cbr/\u003e32. Mid shot pan solar panels on roof of cottage\u003cbr/\u003eThe British government has pledged to create more environmentally friendly homes and to make all new homes zero carbon by 2016. \u003cbr/\u003eBut how can homeowners go about making existing homes more energy efficient ? \u003cbr/\u003eThe people of Oxfordshire were invited to look  inside some of the 'greenest' homes in the county for inspiration and eco advice. \u003cbr/\u003eA country cottage in a rural setting. \u003cbr/\u003eFrom the outside, this home which is half of a former eighteenth century-stone brewery, looks like a typical renovated cottage in the English countryside. \u003cbr/\u003eOlder houses have a reputation as cold and drafty buildings - but this one is cosy inside. \u003cbr/\u003eThe new extension at the back of the cottage is constructed of local unseasoned oak. \u003cbr/\u003eWhilst renovating the building the owner, Sally Harper, insulated the house with natural breathable materials and other energy sufficient devices. \u003cbr/\u003eA 1920s lamp combined with a 21st century energy saving bulb is one way that Sally combines the traditional with the new.\u003cbr/\u003eSally explains that her main eco focus was on insulating the walls, roof and solid floors which has managed to halve overall energy consumption in the home. \u003cbr/\u003eThe under floor heating for instance, uses an old Roman system that combined pumice and a marine aggregate clay laid on the floor in thicknesses of about 300 mm. \u003cbr/\u003eA highly efficient wood burning stove provides the heat for the under floor system which can retain the heat for 20 hours. \u003cbr/\u003eThe original stone and lime mortar walls were insulated with sheep wool batts that are placed between wooden batons and faced with a German particle board composed of compressed sawmill waste which does not use formaldehyde glues.\u003cbr/\u003eSally gives advice to two visitors who are thinking of introducing some of these eco renovations in their own homes.\u003cbr/\u003eKathy Barrett, one of the visitors, is visiting homes taking part in the Open-Eco day to get tips for a flat that she has just bought. \u003cbr/\u003eHer friend, Hilary Moor, is also seeking inspiration from the eco-homes on display.\u003cbr/\u003eSally also receives a visit from a former tutor, Mary Hancock, programme leader of Energy Efficient and Sustainable Building MSC course at Oxford Brookes University, who has arrived with a thermal imaging camera.\u003cbr/\u003eMary is measuring the various levels of heat loss around the room. \u003cbr/\u003eShe notes that the heat loss around the window is greater than in other parts of the room.\u003cbr/\u003eDuring the cold winter months, the wood burning stove comes into its own.\u003cbr/\u003eBut during the summer months, the stove is turned off and then it's up to 4 square metres of solar thermal panels to generate hot water. \u003cbr/\u003eBefore planning authorities could allow the panels in this conservation area, the panels had to be mounted behind a flush roof light.\u003cbr/\u003eIn nearby Oxford, another eco home looks like an ordinary two storey terraced house so common in many English towns.\u003cbr/\u003eBut this mid-Victorian property located in Osney Island in central Oxford boasts several green features including under floor heating. \u003cbr/\u003eArchitect David Hammond explains to visitors some of the main eco-renovations he made to the house he bought in 2000. \u003cbr/\u003eIn the garden, his wife Barbara, talks to another group about some of the heat savings of their system which includes a PV (Photo Voltaic) solar panel installed on the roof of an outdoor office which supplies all of the home's energy demands. \u003cbr/\u003eBarbara says that during the sunny summer months the heat collection system allows her to enjoy many hours of energy-free laundry as the washing machine can take the hot water directly from the system without having to heat the water itself.\u003cbr/\u003eBy far the most striking eco-renovation of this apparently ordinary house is the use of water from the nearby River Thames to run the 6Kw heat pump hidden in the back garden.\u003cbr/\u003eA pump lowered into the river pulls the water at a rate of 35 litres per minute through a filter and into a 1.5 inch (3.8 cm) diameter pipe which carrys the water under the road and the ground floor of the house, through the heat pump, and back into the river.\u003cbr/\u003eInstalling the system was relatively inexpensive:  �290 (600 US dollars)  for a license from the Council and �1452 (3000 US dollars) to dig up the road.\u003cbr/\u003eAsked by one of the visitors whether using water from the river could be used by other houses along the road, Barbara sees no reasons why the pump system couldn't be replicated for wider use.\u003cbr/\u003eBack inside, other would-be eco renovators discuss how to introduce under floor heating in their own homes. \u003cbr/\u003eHowever one visitor Krishna Ramamurthy, admits that the costs of installing solar heating may be too high at present. \u003cbr/\u003eEighteen 'green' houses opened their doors to visitors in the Oxfordshire as part of Britain's largest eco-homes 'Open Doors Weekend' to date. \u003cbr/\u003eThe pilot project, which took place November 24-25, 2007, is designed to show visitors how to create a greener home.\u003cbr/\u003eOrganizers the Climate Outreach Information Network and Oxford University-led ClimateXChange, hope the project will expand and run across the UK in 2008.\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv class='action-container flex justify-between'\u003e\n\u003cbutton aria-expanded='false' aria-label='Read more description'
