Bedzed a report on energy

Overview[ edit ] Most zero net energy buildings get half or more of their energy from the gridand return the same amount at other times. Buildings that produce a surplus of energy over the year may be called " energy-plus buildings " and buildings that consume slightly more energy than they produce are called "near-zero energy buildings" or "ultra- low energy houses ". To read about recent examples of newly built houses with zero net energy use and examples of renovated existing houses with a zero net energy use see here.

If at design stage, consideration is given to the orientation of the houses, the layout of the rooms and the distribution of the windows, you can reduce energy consumption by 10 per cent to 15 per cent at no extra cost to the developer.

First, orientation and layout. Conversely, you want the larger proportion of your glazing on the south side to let the sun in to warm the house. You might put the entrance with a draft lobby on the north side of the house. A long, thin building is going to have a very large external envelope area compared to a cube.

You only have to look at vernacular architecture. The main house, together with a series of outhouses form a square, with the main house and the larger windows facing south, with the outhouses providing shelter from prevailing winds and concentrating passive solar gain into the dwelling.

Smaller windows are found on north elevations, larger ones on the south. Looking to site conditions therefore is something that we just need to re-learn rather than learn from the beginning. When considering orientation, designers, suddenly blind to the sun, looked at planning controls, views, alignment with roads Goulding, like everyone else interviewed for this article, uses one word repeatedly.

Once you know the constraints of the site that you have The path which we now know building regulations will follow, coupled this time with the sluggish construction sector makes the case for passive solar design even more compelling.

Bythe current regulations, which seek a 40 per cent reduction in both energy demand and carbon emissions together with the renewable energy obligation will be upped to 60 per cent reductions and, it is rumoured, a more substantial renewable energy contribution.

At that point, we will be so close to the introduction of passive house standards that to secure comparative advantage, it will make sense to aim for that standard of construction in any case. Roof mounted solar panels on the eco-buildings at Vauban, Freinburg.

Note the eco homes are oriented towards the sun, whilst many of the conventional buildings are facing east or west But do these imperatives restrict design?

Does this mean we all have to live in south facing cubes with a 40 degree roof pitch. You can compensate for that by having a higher specification. In an Irish context in particular, dealing effectively with wind is almost as important.

The means employed by vernacular architecture to defend structures against prevailing winds remain open to designers today. But in addition to landscape and planting, designing for air-tightness has emerged as the most successful modern means of protection from wind.

While almost any structure can be made air-tight, the building forms most amenable to air-tightness are the simplest.

BedZed Case Study Aside from car use and buying exotic foods, the single following energy saving strategies have been implemented biggest impact each of us has on our environment has in BedZed to achieve zero carbon dioxide emissions: to do with the way we use and run our buildings. Most buildings (in general) behave like gas guzzling cars and 1. The Beddington Zero Energy Development (BedZED) is the largest UK eco-community project experimenting in sustainable living. This report explains how urban planners are experimenting with.

The more complex a building is, the more construction interfaces it has, the more potential points of failure. The more complex the design, the more work will have to be done in adopting the air-tightness strategy to cater for it. Having said that, some of the more popular Irish design forms do present particular challenges.The Beddington Zero Energy Development (BedZED) is the largest UK eco-community project experimenting in sustainable living.

B E DZ E D A report on energy efficient design principles applied to Beddington zero (fossil) energy development at Beddington, Sutton Otman Gusbi Introduction Beddington Zero Energy Development (BedZED) is a housing development designed by Bill Dunster Architects (now known as Zed Factory) in partnership with the Peabody Trust and the .

Carbon emissions. Although carbon emissions from housing have remained fairly stable since (due to the increase in household energy use having been compensated for by the 'dash for gas'), housing accounted for around 30% of all the UK's carbon dioxide emissions in (40 million tonnes of carbon) up from % in as a proportion of the UK's total emissions.
