But when it comes to sustainable design and construction, practical ways of energy saving, and give your home a low carbon footprint, it can start quite seem quite complicated. Do you build a particular standard, and if so, which one should you choose and why? Can you make a green building extension or renovation of an existing property? And how much does it really cost to build a green home, and this is reflected in its market value or reduce the cost of living in it?
Three experts with experience of design, practice-management project and building houses eco answer some key questions and share their opinions on the essential information you need to know about building a green home.

what is a green home?
a green home is a green home low impact. This means that it is designed and built using materials and technologies that reduce the environmental footprint and energy requirements carbon home.
"The focus is on energy, which is natural because your carbon footprint is a measure of the amount of energy 're eating," says Ryan von Ruben. "But it's not just energy consumption. It also goes for the way the building is designed the way it is constructed and how it is used thereafter. It's about the big picture.

to what standards can eco houses built?
There are a variety of ways to accredit green homes. These provide some standards and certify that a building meets them. The standards may be more stringent or more relaxed, as you target a truly zero carbon house or simply a more sustainable and home environment. The standard for you will depend on your needs and wishes.
popular standards in the UK include the Code for Sustainable Homes and Passivhaus (both that you will find more about you read on) among other options. If your building permit depends on the realization of a particular standard, it may require you to meet a certain level of code. Or you may decide that you have a preference for one approach over the other.

What is the code for sustainable homes?
code is a government program that works by assigning a new house a rating level 1 to level 6. The rating is based on performance home compared to nine sustainability criteria, which are combined to assess the overall impact on the environment. Level 1 is the entry level above building regulations, and level 6 is highest, reflecting a zero carbon home which meets the highest sustainability standards.
The sustainability criteria against which new homes are measured by the Code are: energy and carbon emissions; water; materials; surface water runoff; waste; Pollution; health and wellbeing; management; and ecology.
"One of the things on the code system is that it takes a holistic approach," says Paul Younger. "This means that the requirements can include things related to home security, or accessibility and ensure a house is suitable for use on a life that elderly occupants - a corridor is wide enough to a wheelchair, for example, or the stairs, you can convert to a stairlift. These are very good standards, from the perspective of an owner, but not necessarily good for someone who wants to focus only on the carbon footprint and sustainability. "

what Passivhaus?
is an international Passivhaus low energy design standard. Heat loss of Passivhaus buildings is minimized to the extent that they hardly need any heating at all and often do without a conventional heating system. "The Passivhaus standard has more of a focus on the building structure," says Paul Younger. Especially popular in Germany and Scandinavia, there are thousands of houses Passivhaus in the UK and Europe.
A Passivhaus can be constructed using almost all building systems; it just has to meet certain standards of low energy demand for space heating. A house built to Passivhaus standards will generally featured serious insulation, triple-glazed windows with insulated frames, sealing levels to look amazing and mechanical ventilation with heat recovery.
Intelligent design also features, making the most of the natural world to ensure home runs perfectly in terms of heat and light. "Intelligent design and placement can mean that you get a net heat gain through windows face south, said Alan Budden. "But then you must be careful not to oversize them, in terms of getting too much heat in the summer. It is quite a complex calculation to get the right balance. "

What are the other options?
There are a number of other standards, national and global, you can choose to build. But make sure you work with a reputable standard. "Many certification systems, including the Code for Sustainable Homes, are based on research that comes from the Building Research Establishment (BRE), so it is authoritarian and science," says Ryan von Ruben.
"Decide what standard to build to will really depend on what you are trying to achieve, says Paul Younger. "Some construction permits require a particular level of code, such as a code 3 as a minimum. Then you'll need to work with a code evaluator to develop goals and strategies to meet the requirements of the code you are working toward.
If you don 't need a building permit, it is also possible to follow the recommendations and best practices, or choosing a manufactured home that meets the most standards, but not actually pay extra for home officially accredited to a particular standard.

What features could include an eco house?
With a conscious perspective of energy, a green home is likely to include a number of features designed to make it sustainable to build and run.
These could include renewable energy systems, sustainably produced and highly effective insulation, triple glazing, solar panels, geothermal heat pump, rainwater harvesting systems, including perhaps a green roof planted with wildflowers, energy efficient lighting, ventilation systems with heat recovery, and more.

is it possible to make a green building extension or renovation?
Yes, it is possible. But because you are working with a pre-existing building, it is not quite as simple as the white canvas a new construction job. It is particularly complicated as regards the construction of a particular standard.
'Passivhaus is the main standard we aspire, "says Alan Budden. "But if we work on a renovation of an existing home, EnerPHit standard may be more appropriate." The EnerPHit standard was developed as a good restoration practice guide for Passivhaus style renovations, and takes into account the limitations of working with an existing building.

What are the costs of building a green home?
As with any construction project, costs can vary greatly depending the specification. Will it cost more to build a green home? Not necessarily.
"If you build the code, you may be at a slightly construction costs look higher than for equivalent new building that are not eco-friendly," says Paul Younger. "It may cost 5% to 15% more. Passivhaus, meanwhile, offers houses can be built to its standards without increasing costs in prices. "

What is the value of green homes?
house prices can vary greatly depending on the location, size and even interior design, it is difficult to make generalizations about whether green homes have a higher market value . Some say they do not, while others argue that the energy efficiency of homes eco makes more desirable to potential buyers.
"We worked on the development of new green homes in Bath, zero carbon and built to a standard code 5, Paul says Younger. "Interestingly, we have had many discussions with real estate agents, who initially do value the property differently from others of the same size in the region. But when they actually started to commercialize the system and promote the benefits of ecological housing, this results in a higher sales price. "

what is it living in a green home?
The experience of living in a green home is unique. As expected, operating costs will be significantly cheaper because of the lower energy consumption. "In three years, the cost of energy will typically £ 1,000, while income from photovoltaic cells could put £ 2,000," says Paul Younger. "So there may be significant long-term savings on running costs of the house.
You can also expect the climate in the house to be regulated more smoothly, with less variation. "The other thing that comes with a green home is comfort, 'said Alan Budden. "When you live in a green home, it will be comfortable, especially in terms of temperature. You should be able to sit right next to the window on a cold day and still be a reasonable temperature.

How can I get the right design?
Commissioning of an architect to create a design that is specific to your needs and the site is an option. Otherwise, you may consider working from an existing template or using prefabricated frame, which saves significantly on the initial effort.
'Consider a timber frame system off-the-peg which comes with a code for sustainable homes or certification Passivhaus "advises Paul Younger. "For example, we built a home on the Gower costing less than 5% more than a new building disrespectful of the environment would. If you want a relatively conventional design of the home, it can cut costs and give you precise standards of waterproofing and insulation.

is a key architect?
If you want to build a house entirely custom, or adapt an existing design to your own specifications, then you will need an architect. The expertise of an architect can bring will not only related to the design, but their work experience on similar projects in the past.
architects have the experience to deal with a range of new technologies, "said Ryan von Ruben. "They met a few things they think are worthwhile and others they found to create more problems than solutions. That's the experience you seek.

Do I need a specialist builder?
Your builder of choice is certainly as important as the design architect or home you choose. "If you want to be environmentally friendly, then choosing that you use to build your project may be the most important thing," said Ryan von Ruben. "There is not that on the use of materials from sustainable sources, but to have the expertise to work with them, and a respectful way of the environment management of construction waste, which means tracking and recycle it appropriately. "
If you are working with an architect or a design firm, they may already have experience working with manufacturers that they would recommend. If you are a manufacturer sourcing independently, you may want to ask about their past experience working on green homes, and work with one of the key materials or technologies you plan to use.
