2Basic elements of a traditional heating & cooling system Traditional heating & cooling systems present considerable disadvantages, especially a high level of energy consumptionBasic elements of a traditionalheating & cooling systemMain disadvantagesChillerEither water to water or air to water: in buildingsAir to air: in households.Cooling towersIn water to water systems.Mixing ventilationRefrigerated air recirculation to reduce energy consumptionHigh energy consumptionIn office buildings, heating represents between 40% and 65% of electricity consumption (1)Noise PollutionInternal: produced by fansExternal: produced by cooling towers and air to water machinesIncrease of legionella scattering riskIn water to water systemsPoor air qualityHigh incidence of colds produced by air circulationFrequent complaints from users due to overexposure to either cold or heat(1) Source: La Vola Companyia de Serveis Ambientals, SAL

10Aerosol emission measures obtained through hydro sensitive paper AvdanSol hydro-solar modules not only save energy but also gives a number of benefitsBenefitsEnergy savings in heating, cooling and hot waterEasy architectonical integrationHeight < 1 mRequires little surface (from 3% to 5% of the surface considered) *Require no reinforcement of the surface it is settled onWeight < 25 kg/m2Lack of noise and vibrationsIt doesn’t include mobile mechanical parts of any kindHighly reliableUse of an auxiliary air to water machine to cover long periods without sunStrong system with little maintenance requirementsNo freezing nor overheating risk, no mobile mechanical partsMinimize legionella scattering riskAerosol scattering considerably lower if compared to refrigerating towersLow risk ranked, within the same category of park fountains and irrigation systemsAerosol emission measures obtained through hydro sensitive paperRefrigerating towerAdvanSol roof* Depending on the particular building, it may be necessary to consider an additional collecting surface for winter. Such surface will depend on the target energy qualification.
11Radiant floor provides high energy efficiency and great comfort feeling BenefitsHigh energy efficiencyIt works at temperatures very close to environment onesIt works only on the area occupied by people (stratification)Reduces the thermal load produced by the radiation getting in through windows and doors or glass walls.Reduces the transmission thermal load getting in through windows, doors, floor and roof.Highly energy selective (supplies heat or cold only where required)Lessen thermal load oscillations and, therefore, compression consumption.Great comfort feelingThermal sensation in summer similar to the one at a cathedralHomogeneous and silent distribution of energyThermal inertiaKeeps heating & cooling inner conditions whenever a failure of the system or an electricity supply disruption occur.
12Heating & Cooling traditional system AdvanClim system(AdvanVent displacement ventilation)Heating & Cooling traditional system(mixing ventilation)Finally, AdvanVent displacement ventilation reduces even more energy consumption and provides higher comfort and air quality levelsAir is introduced at low temperature and high speed, being mixed with the air of the roomsRefrigerated air is recirculated to reduce energy consumptionThe air introduced is only the necessary one to ventilate the buildingIt is introduced air at a moderate temperature and at low speedHot air is expelled, instead of mixing it with refrigerated airAir is not recirculated and no turbulence takes placeEnergy consumption savingsExpels convective thermal loadsIt works at temperatures close to comfort onesDrives little air flowIt works only on the occupied areaOnly where it is necessaryAllows a higher use of free-coolingReduces consumption on last floorMakes it unnecessary the use of fans and recirculation filtresProvides higher comfort levelEnsures a cleaner and healthier airReduces colds incidenceBenefits
13As a result, AdvanClim system supplies high energy savings that may reach up to 73% AdvanClim system energy savings compared to traditional heating & cooling systemsEnergy savings up to 73%-30%-73%-20%-30%-30%Note: The figures have been taken from a traditional system based on air to water machines.

15Buildings incorporating AdvanClim system usually obtain “A” energy efficiency category in Heating & CoolingExample 1: Nature Educational House (Córdoba)Example 2: ESESA Educational BuildingClassroomsMain buildingEn este cuadro podemos apreciar la comparativa entre diferentes sistemas de climatización:Sistemas basados en máquinas agua-agua con torre de refrigeraciónSistemas basados en máquinas agua-aguaSistemas VRV (Volumen variable de refrigerante)Paneles solares con suelo radiante para calefacción, y máquina aire-agua para refrigeraciónAdvanClimComo podemos observar, AdvanClim no es el mejor en todos los factores, pero sí que es el que proporciona mejores características globales (es el que tiene mayor número de semáforos verdes).En lo único en que es aventajado por otros sistemas es en el coste de instalación, que para edificios de menos de m2 es superior al de sistemas agua agua-agua y aire-agua, y en el riesgo de legionella, que es nulo en los sistemas aire-agua o VRV.Heating & Cooling categoryAAALighting categoryCCBOverall categoryAAB
