In fact most are awaiting certification 6

Developers have little choice: the duty to construct might BBC buildings (buildings low consumption), respecting thermal regulation RT 2012, will enter into force on October 26, 2011, for offices and public facilities, January 1, 2013 for housing. From these dates, all requests for building permits will be required to conform. This year, since January 1, the aid to housing, such as PTZ , reserved for the acquisition of a principal residence, and the Scellier, for rental investment, are already clearly doped when they are used for the purchase of energy-efficient housing.

Professionals say anticipated this constraint lest they sales collapse, especially in the market of the tax exemption. Going green since the end of the year 2009 for Bouygues Immobilier and Bouwfonds Marignan Immobilier. Kaufman & Broad BBC since March, new manufacturers followed the movement in July, Tagerim in September. After the delivery in November of a first group of houses at Cesson, in Brittany, Nexity announced that 80 of the programmes implemented construction in 2011 will comply with this standard. The Union of houses, the Federation of individual builders is less optimistic or realistic and spoke instead of 15 to 20 of green licence for a production of about 200,000 and is expected to net acceleration in the coming months.

Transitional phase

While only 3 of building permits housing fell into the mould in early 2010, more than 90 of new programs marketed (but not constructed) therefore now have the label. In fact, most are awaiting certification: 6.641 houses in diffuse sector, 7.615 houses built by developers, 71.295 apartments and 209 tertiary operations, approximately 1.8 million of square meters according to the figures of the Observatory of the association Effinergie to October 29. Buildings completed, audited and approved are much less numerous: 883 houses, 52 operations grouped homes either 550 dwellings, 2.675 apartments in collective programs and 4 office buildings (total of 30,000 square metres).

Launch and deliver a housing or offices operation takes two to four years: BBC buildings marketed in 2010 and in 2011 will be completed to better end 2012 or 2013. The Green batch of 2011, already sold, will therefore be even lean. Nothing in sight for Kaufman & Broad, new manufacturers and Tagerim. Bouwfonds Marignan Immobilier prepares to engage in September 2011 residence first BBC 65 apartments in Annecy-le-Vieux (Haute-Savoie). Nexity promises 227 dwellings, Bouygues real estate Announces approximately a dozen programs, or 500 homes on a total production of 6,000.

There is still some underperforming units in stock. "It's a handful of batches acquired in 2010 and which were the subject of cancellations for reasons", said Hervé Puybouffat, President of Tagerim Promotion. "200 To 300 housing", said Philippe Jossé, Director General of Bouygues real estate housing. "Less than 10 of our commercial offer is now non-BBC and three quarters of these programs are located in the Anru areas." "In these neighbourhoods by renovation, purchasers usually have too tight budgets to support the additional costs due to the BBC", argues Jean-Philippe Bourgade, President of Bouwfonds Marignan Immobilier. In 2011, these purposes of program will be difficult to sell. "For these lots not"bébéçables", it is not excluded to offer a discount or offer notary fees", indicates, realistic, the Kaufman & Broad proponent.

Additional costs incurred in certain

Almost all of the new developed housing for sale on plans, starting this year should present the famous label and an undeniable extra cost. From 5 to 10, as State sponsors 15 To 20, as the think individual homebuilders and a recent study by the Xerfi Council "It takes 120 to 160 euros more per square metre", says Patrick Zamo, Director General Ile-de-France in Kaufman & Broad. Green Office, the first tertiary building positive energy built by Bouygues Immobilier, delivered at Meudon in the Hauts-de-Seine, in March, cost 18 more than a conventional building, particularly because it supports 4.300 square metres of photovoltaic panels. From Rolland Germain calculations, the CEO of the Geoxia group, a household wishing to stay in the BBC pay her house up to 27,000 euros more if he chooses an electric heating. These additional costs are not inevitable (see next page). They should fall with the industrialization of the production of new materials and once trained personnel of the enterprises. This is not for tomorrow. Still absorbable with very low interest rates, this new price increases may not be if they were. Yet is what is expected.
