Palača pravde u Antwerpenu / The Hall of Justice inAntwerpenCover storya completely achievable and lucrative solution with thestate co-financing the project.Sun as the Source of EnergySolar energy has always been the foundation of life in theevolution of the human race and has actively been usedsince 7th century BC, first of all for setting a fire. Today’stechnologies for using solar energy include all kinds of applications,from solar lighting for gardens to automobilesrunning on solar power. The contemporary society recognizednumerous applications of solar energy such as thereduction of dependence on organic fuels, improvementof air quality, reduction of conservatory fumes, productionand installation of solar systems in our homes. Suchsystems absorb solar energy, heat air of liquid, transmitheat and pass it on to water or directly into the spacethat is being heated. The system for heating spaces witthe help of solar energy can be passive and active. Passivesystems are usually cheaper and simpler than theactive ones, and the most famous example of passiveuse of solar energy is the conservatory respectively thegreenhouse. The passive system for heating houses usesthe heat with the help of the elements in the house itselfin a similar way – big windows facing south, floors andwalls which absorb the heat during the day and releaseit during the night. Active system for heating spaces consistsof collectors that absorb and collect the solar heat,and contain electric ventilators or pumps that serve asheat transmitters. Such systems also have a heat storagesystem in order to assure the apartment is warm enoughduring cloudy weather or throughout the night.The First Passive House in CroatiaIn 2005 architect Ljubomir Miščević projected an energeticalredesign of a previously existing facility in order tomake the first passive house in Brestovje near Zagreb. Itis the so called “house without heating” owned by theMihaljev family. For the first time in Croatia the dream ofa possible low-energy architecture and energetic independencehas come true. Profesor Miščević is also theauthor of an architectural project “The Croatian SolarHouse”, a national developmental science-researchproject which is being performed by the Centre for RenewableEnergy Sources – CERES. The house will be built inZaprešić as a part of the first Croatian Sunny city with universitycampus, technological park and settlement withseveral residential buildings and all the facilities will be onthe level of the energetic standard of a passive house.The Low-energy and Accumulation YTONG HouseThe bearing and partition walls of economical houses areoften build out of aired concrete Ytong blocs. As a buildingmaterial for the construction of a facility’s structure,Ytong deals with thermal protection without additionalthermal insulations according to the contemporary thermalinsulation regulations and alongside additional isolationit is ideal for building passive and low-energy houses.The materials assure superior thermal insulation and sound23
