// Description
CasaSo laris (www.casaso laris.ro ) is a single-family dwelling lo cated in no rthern Bucharest. It is an active house - pro duce
mo re energy than is needed fo r current co nsumptio n - thanks to the co ntributio n o f pho to vo ltaic panels. Casa So laris is
equipped with thermal panels, used fo r bo th do mestic ho t water and fo r heating in winter. To this end, it uses an innovative
heat sto rage in the gro und in summer captured, eliminating the need fo r heat pumps.
Building energy efficient and intelligent so lutio ns fo r heating and cooling, reduce heat to appro x needs 50 kWh / sqm / year and
leads to a climate co ntro lled indo o r humidity and temperature unifo rm witho ut anno ying drafts.
Casa So laris is a ho me healthy, co mfo rtable and has a po sitive impact o n the enviro nment.

Dé m arche dé ve lo ppe m e nt durable du m aît re d'o uvrage : I wanted to build a sustainable ho me based o n renewable
energy and green ho use, in harmo ny with the natural enviro nment. I wanted to have a co mfo rtable ho use with a healthy indo o r
climate: take advantage o f fresh air co nstantly, but witho ut dissipate heat. I wanted to (i) demo nstrate that we can build such a
ho use in Ro mania, with the techno lo gy available and at a reaso nable co st. Last but no t least, I wanted to give so me peo ple
energy and inno vative spirit, the ability to realize his dream. His help to change the mentality and living standards. I ho pe that
such a co ncept ho use and applied techno lo gies to be ado pted by as many peo ple and o rganizatio ns.
De script io n archit e ct urale : Casa So laris was designed so that, in additio n to aesthetic and functio nal co nsideratio ns to
no rmal ho uses, to meet specific requirements and their o wn energy systems and green ho use co ncept. The ro o f has been
designed so that 2/3 o f the surface o f the sun to be o riented at an o ptimum angle to maximize the efficiency o f pho to vo ltaic
and thermal so lar panels. Also , by co nfo rming to the architectural elements o f the facade, windo w shading was do ne during
the summer to limit so lar gains, increase indo o r co mfo rt and lo wer energy co nsumptio n fo r co o ling. Shading is do ne so with
architectural elements (eaves, balco nies, etc.) and by ro lls o rientatio n east / west. Functio nally, the ho use is an apartment with
fo ur ro o ms o n the gro und flo o r has the functio ns o f day (living ro o m, kitchen, bathro o m) and also a ro o m with destinatio n
o ffice o r bedro o m and upstairs has two bedro o ms with dressing ro o m, bathro o m, laundry / dryer, sto rage. The bridge is an
additio nal sto rage space; Its central area is spacio us eno ugh (and height) to allo w co nstructio n o f a space study o r relax.

emphasizes energy independence, the o nly external co nnecto r is the electricity. It is dual ro le: co nsumers and pro ducers, to

System radiant hydro nic heating and co o ling o f very lo w temperature in the walls and ceiling,
scattering aluminum plate under the plasterbo ard. Unify into a single system bo th functio ns
co nditio ning (heating and co o ling). Size heat radiating surface temperature clo se to the ambient
heat and lack o f unifo rmity gives air drafts in the ro o m. This pro vides a high enviro nmental
co mfo rt. The no velty lies in the ambivalence system (used fo r bo th heating and co o ling), in
placing a ceiling (unusual), which allo ws an area larger than the radiant flo o r and in their o wn
