Eco Friendly Building - Sustainable Design - Passive House
Sustainable design is an architectural concept that sets out to produce a building that is in harmony with the natural features and resources on, and surrounding, its site
Eco Friendly Building
At the heart of Eco Friendly Building is ‘Sustainability’
Probably the most coherent definition of sustainability and certainly one relevant to construction, was created by the Brundtland Commission which defined sustainable development as development that ‘meets the needs of the present without compromising the ability of future generations to meet their own needs’
Eco Friendly Building - Sustainable Design
Eco friendly building practices offer an opportunity to create environmentally sound and resource efficient buildings by using an integrated approach to design.
Eco friendly building design promotes the conservation of resources, considers environmental impact and reduces waste.
Eco friendly buildings create a healthy and comfortable environment, reduce operational maintenance costs and address location issues, like access to public transportation and other community infrastructure facilities.
Eco Friendly Building - Low Energy Technology
Eco friendly building typically employs high levels of insulation, energy efficient windows, low levels of air infiltration and heat recovery ventilation. Eco friendly building will also use passive solar design techniques or active solar technologies. To reduce energy needs for domestic hot water these buildings may also use hot water recycling technologies to recover heat from showers and dishwashers.
Eco Friendly Building - Passive Solar Design
By employing passive solar building techniques, eco friendly buildings are compact in shape to reduce their surface area, with windows orientated towards the equator to maximise passive solar gain. Decisions on the orientation of the building must be taken at the design stage. There will be other influences, such as planning matters, access and the position of adjacent dwellings. There may also be other constraints such as privacy and views which need to be taken into account. Such competing factors need to be reconciled to arrive at an optimum design.
Eco Friendly Building - Passive House Design
Eco friendly houses can be constructed from either dense or lightweight materials, but some internal thermal mass is usually incorporated to reduce summer peak temperatures, maintain stable winter temperatures and prevent possible overheating in spring and autumn before normal solar shading becomes effective.
Eco Friendly Building - Space Heating
In addition to using passive solar gain, eco friendly buildings make extensive use of intrinsic heat from internal sources. This is, waste heat from lighting, domestic appliances and other electrical appliances, as well as body heat from the building occupants. Together with comprehensive energy saving strategies this means that a conventional central heating system is not necessary.
Eco Friendly Building Design
It is important that designers of eco friendly buildings know how the occupants of a new house will interact with the passive technologies that are employed in the building. Equally, when the occupants move into the new house they should be well informed as to the technologies installed in the house. They should be able to operate the controls that make the house work efficiently to gain the most benefit from the energy saving technology.
Eco Friendly Building - Professional Advice
Depending on climate, location, building design, personal preferences, availability and cost, different eco friendly buildings will adopt different types and combinations of low energy and renewable technologies. In order to ensure that the balance of these technologies is such that the dwelling works efficiently in all seasons, is comfortable to live in and complies with the demanding zero energy standard, it is advisable to obtain professional advice from appropriately qualified building professionals to give advice on the design and produce the necessary calculations.
Eco Friendly Building practices consider the entire life cycle of the building and its components as well as the economic and environmental impact and performance
