Aiguasol is recognized within the construction and renewable energy sectors for our objectivity and neutrality as a result of our independence and high scientific rigor.With an integrated vision, Aiguasol provides services that are exclusively centered in the field of energy systems. These services can be studies, projects and research and development projects, with a high level of specialization and experience in urban planning, construction, industrial processes and power generation, with a focus on energy planning, savings measures, energy efficiency, process integration and renewable energy implementation.This rigorous and precise approach used on tasks undertaken at all levels and in all areas of action require, for consistency, the use of the most advanced and proven calculation tools. As a result, Aiguasol has become a reference in Spain for dynamic simulations of thermal systems, being the exclusive distributor of industry standard programs such as TRNSYS or TRNFLOW as well as being a TRANSOL developer.The Aiguasol team is made up of more than 20 professionals with a high level of technical and scientific experience. They include engineers, PhDs, architects and physicists who have notable experience both in private companies and research centers.Currently, Aiguasol has offices in Barcelona, London, Bogota, Lisbon, Oiartzun and SantiagoAiguasol proposes the most efficient solutions, from both an economical and energy point of view, with a clear orientation towards savings on investment and operational costsServices: Energy Consultingphoto: Energetic optimization in greenhousesVolatility in energy costs, new regulations relating to energy efficiency and above all the political and social concern about reducing CO2 emissions in order to control climate change have made energy and its efficient use a transversal element to take into account for any action, be it in industry, transport, construction, urban planning or energy generation.The transversal introduction of energy in projects requires specialized experience, tools and knowledge that often exceed the specific knowledge and technical capabilities of the professionals or companies who are responsible for carrying out a project. In these cases, an energy consultant is required.Aiguasol has accumulated a wealth of experience working on energy projects, both at the consulting level, through research or implementation, as well as having the most advanced and powerful calculation tools. This allows us to offer our customers an energy consulting service which offers the best guarantee of success and total independence. Our integrated vision for carrying out projects translates into the most efficient solutions, from both an economical and energetic point of view, with a clear orientation towards savings on investment and operational costs.This service centers on four areas:Urban PlanningIn the building sector, reducing the impact associated with energy consumption requires the introduction of energy as a transversal element that needs to be considered from the beginning in the urban planning stage as it conditions subsequent action. Working in this phase, it is possible to optimize networks, densities, heights, constructive typologies and uses, while reducing energy demands from the neighborhood to legally required and economically viable limits or even generating different scenarios.Based on these energy scenarios, we can simulate the behavior of different energy system solutions with varying degrees of centralization and technologies, identifying the energy performance and efficiency of each set of actions and for each global solution.ConstructionAt the building design level, Aiguasol energy consulting integrates naturally with the multi-disciplinary design team. The collaboration goes from conception to execution, from providing general ideas on building placement, form or orientation to the optimum dimensions of heating and cooling systems or the design of construction solutions. By avoiding superficiality and using the utmost scientific rigor, the most advanced tools and by working in close collaboration with the architects, we deliver buildings which have the best thermal comfort and natural lighting, with lower energy consumption, and less associated emissions and often with low investment costs.Aiguasol has participated in the design of all types of buildings in the service (offices, hotels, hospitals and health clinics, public buildings…), industrial (warehouses, manufacturing facilities…) and residential sectors. The tools used for these services range from dynamic simulation with TRNSYS and TRNFLOW to CFD analysis, through simulation of natural lighting such as RADIANCE, and any other special software which is required. The Can Ricart Public Swimming Pool Building- collaboration with Vora ArquitecturaIndustry and Mining For the design and optimization of industrial processes, Aiguasol provides a comprehensive as well as detailed overview that optimizes energy production and distribution systems, integrates processes with Pinch-Point analysis, including at the dynamic level, or combining sources and forms of energy. We always work to find the optimal combination and design, as well as the most profitable investment for our customers. Our proposals are carried out using detailed process or assembly models and include process integration coupled with renewable energy or regulation strategies.GenerationGenerating renewable or efficient conventional energy, be it heating, cooling or electric, cogeneration or trigeneration, is one of the most important fields in energy consulting. Market growth in renewable generation with hybrid sources such as solar-thermoelectric with biomass, or poly-generation systems can include multiple sources and technologies to capture and transform energy. These are often governed by complex regulations. Aiguasol provides its customers with the necessary tools and knowledge needed to succeed in this area.Building Energy Audits in Codelco's Andina divisionTrends and Highlighted Services Energy Services / ESCOThe future and opportunities in the energy field depend on determining the optimum generation scenarios along with the action and operational margins for grand consumers. Controlling these translates into direct benefits, both for the end user as well as the energy manager, especially when the manager is an energy service company. According to the European Parliament Directive 2006/32/EC, an energy service company (ESCO) is defined as “a natural or legal person that delivers energy services and/or other energy efficiency improvement measures in a user’s facility or premises, and accepts some degree of financial risk in so doing. The payment for the services delivered is based (either wholly or in part) on the achievement of energy efficiency improvements and on the meeting of the other agreed performance criteria;” As such, it is fundamental to determine with the maximum reliability, the least cost and greatest velocity, the margins of this type of activity.A step forward in the field of evaluating the behavior of energy systems and the optimization of savings measures, based on rehabilitation but also operational, is the development of META-MODELING (reducing a model to a function including the most significant parameters). The use of META-MODELING simplifies the analysis requirements and reduces calculation costs while maintaining the reliability of the results. META-MODELING has not been possible until now due to cost and technical issues. It allows for the automation and generalization of audits for a group of buildings at a much lower cost, intelligent building management, simplifying the management and compliance with regulations or the intelligent generation of energy.Some examples of META-MODELS done by Aiguasol are the METASOL calculation methodology (for calculating solar fraction estimates in solar thermal systems in Spain – CHEQ4) or the TOBEE project (holistic analysis of energy behavior in transparent office buildings in Mediterranean climates).08Certification and AccreditationIn the European legal framework, Directive 201/31/EU, on energy efficiency in buildings, requires the issuing of an energy efficiency certificate for all buildings that are built, sold or rented. As a result, every member country of the EU has wholly or partially adapted this rule to the reality of their construction sectors (some countries are still in the process of adopting it). Internationally, standards are still uneven, though some countries have adopted energy certification protocols or are in the process of doing so.Beyond fulfilling legal requirements and independently of the geographic location, it is possible to take a step further developing private environmental accreditations such as LEED or BREEAM which represent respect for the environment and the rational use of energy by society. These accreditations depend strongly on the energy vector and its derivatives, as well as the measures related with water, building material and user specific services. Although accreditations have been traditionally recognized within the construction sector, in the past few years they have also reached the end user, who they were initially planned for.In this sense and particularly in the hotel sector, according to recent studies, accredited installations can get twice as many clients, with more than 85% of tourists preferring green certified lodgings and willing to pay up to 8% more than a conventional hotel. In the office sector, many companies ask for a high level certification when renting or buying their future workplace.Aiguasol carries out government regulated energy certifications in each country and assesses and participates in the energy aspects for the implementation of environmental certifications.09"High level energy certication with controlled levels of investment As independent engineers, Aiguasol can carry out an entire energy system project from design to implementation Services: ProjectsEnergy system design takes shape through execution and operation, which need to be done with the highest quality and coherence with the developed concept. In addition, the best advice with the maximum certainty and security results from the fusion of the conceptual and theoretical tasks with work site experience.Aiguasol, as an engineering company, is able to put the systems we have designed into operation, not under a turnkey structure, but as independent engineers. At Aiguasol, we believe that only an engineering firm which is independent from the economy of execution can assess, optimize, design, plan and direct the construction of an energy system with the maximum guarantee of fidelity to the system that was designed. EPCM ContractingAiguasol works under EPCM contracting to offer our customers the best guarantee for success and to protect your interests.Recently, though not yet widespread in all sectors, EPCM (engineering, procurement and construction management) contracts have started to gain acceptance. In this type of contract, the contractor develops the engineering, is in charge of procurement and manages the construction as owner’s agent.Aiguasol is willing and able to integrate within multidisciplinary teams.Solar thermal system at Vall Hebron Hospital, Barcelona.11The principal companies, universities and research centers in the energy field use the global industry standard software that Aiguasol distributesServices: SoftwareDesigning and modeling energy systems is based on two pillars, which are knowledge and calculation tools. In the case of calculations you need to have in mind the dynamics and the physics of the energy systems which are closely linked to climate and inertia or capacity to store energy, which are variable by nature.Aiguasol offers the most well suited and most prestigious dynamic simulation tools to accurately predict the energy consumption of an energy system over time, typically a period of one year. These tools permit the consideration of other factors beyond energy consumption to measure the efficiency of a system, such as reduction of emissions of contaminating gases, thermal comfort or economical feasibility.The principal companies, universities and research centers in the field of energy use the programs that Aiguasol distributes, programs that are industry standard reference software for researchers and engineers around the world. The areas of use run from solar thermal and photovoltaic systems, bioclimatic architecture and efficient buildings, to heating and cooling systems, geothermal or cogeneration, fuel cells and other renewable energy systems.The daily use of simulation software in our projects and energy consulting work ensures a high degree of quality in the following services:· Specific training in the use of software· Development and personalization of software applications· Energy system modeling· Development of new components for energy analysis· Validation and viability of new technology· Personalized applications for e-learning or free distribution13TRNSYS Pronounced “transis”, it is a complete simulation environment.

Highlights include an analysis of the main meeting room and insulation solutions for the roof, as well as the shading of closings in order to reduce thermal loads.The heating and cooling system is based on a system of heat pumps and geothermal exchangers and the emission systems are based on a binomial, fancoil and or radiating floor in function of the desired inertia in each zone.Energy Optimization Consultants for the Costanera Center Megaproject, Santiago Revision and analysis of the level of energy efficiency and the potential for savings in the group of buildings of the Costanera Center which was designed to include a shopping center, parking, four office buildings and a convention center. The diagnostic included a 300m high skyscraper with 80,000m2 of office space designed by architect Cesar Pelli, as well as Tower 4 which is 112 m high with 17,000m2 of mixed use offices and a four star hotel. The Aiguasol’s expert consulting centered on the revision of the energy efficiency of the planned heating and cooling systems, as well as researching technical proposals to improve the lighting and thermal comfort parameters of the inhabited spaces in the buildings.19The Centro de Ciencias de Benasque Pedro Pascual (CCBPP) expanded in 2007 with the incorporation of the Spanish National Research Council (CSIC), which led to the planning of a new building designed to host high level scientific meetings. The architectural team of Isabel Pascual and Bernardo Fernández won the contract and one of the premises for the development of the project was the incorporation of energy efficiency criteria, as well as the integration of renewable energy.Aiguasol joined the project team at the conception and design phases of the new building. Using dynamic simulation we analyzed and optimized the different façade elements of the building as well as other exterior elements.Aiguasol also analyzed the different options for energy systems before choosing a biomass system based on radiant flooring and integrating a solar photovoltaic system.Optimization of the energy behavior of the new Benasque Pedro Pascual Science Center20Energy Consultancy for Mining Buildings in the Andina Division of CODELCO.Revision and analysis of potential energy efficiency in the Hilton and Hyatt buildings in the industrial sector of the Andina Division of Codelco. The project considered the energy consumption of both buildings using simulation and on site monitoring to propose viable energy efficiency and renewable energy solutions.The project considered the energy optimization of the buildings envelopes and analyzed alternative energy generation such as cogeneration, solar thermal energy, photovoltaic and biomass furnaces. Furthermore, we proposed the implementation of a system of energy management based on remote monitoring and control.21Energy efficiency study at the Ovalle Hospital.The Chilean Efficiency Agency published a bid for an “Energy Efficiency Study for the architectural design of a new hospital in Region IV of Coquimbo”, to be located in the area of Ovalle and with an area of over 30,000m2.Aiguasol won the bid in collaboration with the Chilean architecture firm Arquiambiente.The study can be summarized in three main points:?? ?????????? ??????? ???? ????????????? ??? ????????bioclimatic systems?? ?????????? ??????? ???? ????????????? ??? ???? ???????systems in the hospital?? ??????????????????????????????????????????????Energy Efficiency Guide for Health Establishments- Chil-ean Energy Efficiency AgencyTogether with the architecture firm Arquiambiente we elaborated the official energy efficiency guide for health establishments for the Chilean Energy Efficiency Agency and the Health Ministry.Aiguasol worked on the revision and analysis of successful energy efficiency cases in hospitals, devel-oping design criteria and proposing specific technologi-cal solutions to take advantage of available energy resources. We worked on heating and cooling systems, the selection of lighting systems, centralized controls, water savings measures, as well as proposals for renew-able energy and highly efficient and innovative technologies for heat generation and circulation.22 Infiltration Test and Energy Efficiency RehabilitationEnergy efficiency evaluation of the heating and cooling system for the Torre Sinergia in Temuco Aiguasol carried out a heating and cooling analysis based on projected and installed VRV-GHP along with a study on the alternatives to improve efficiency.Dynamic simulations were run to determine building demand and based on these and on site visits, we analyzed proposals to improve efficiency.In the final proposal, the following measures were incorpo-rated:?? ????????????????????????????????? ????????????????Along with measures to reduce demand:?? ?????????????????????????????????????????? ???????????????????????????????????? ???????????????????????????? ??????????????????????????????If all measures are implemented there will be a savings of 34% over the baseline scenario.Heating and cooling represent 60% of the energy costs for buildings in the tertiary sector in Spain (according to the E4+ Action Plan 2008-2012)For various reasons, in terms of quality and closings, nor-mally there are notable differences between the blueprint and the finished building. With this in mind, some studies have attempted to evaluate the impact of infiltrations and energy consumption and have made some spectacular findings. Correcting infiltration problems can result in significant savings in heating and cooling costs.Aiguasol offers infiltration test services, analysis of poten-tial savings, development of measures and commissioning.23Energy Optimization and efficient energy system in the Charmex office building in MadridCharmex International built a 6,000m2 building in Getafe (Madrid) which will hold its own offices as well as offer office space for rent. The energy goal is to obtain LEED certifica-tion.Aiguasol participated in the construction aspects to reduce demand and design a DEC Desiccant Evaporative Cooling system with the goal of treating the primary building air with a highly efficient system. The DEC system cools or heats, depending on need, through a system of a desiccant wheel and a field of solar collectors which regenerate it or which directly provide heat to the heat battery of the primary air treatment unit.Lonja de Pasaia, optimization of construction solutions and efficient energy systemAiguasol joined the project team at the conception and design phase of the new building, evaluating different options for construction solutions and energy systems, before finally developing and optimizing a heat pump system that uses sea energy.At the same time an additional system using ice based latent accumulation, together with a rotary desiccant wheel to take advantage of latent heat. With these measures, we were able to simultaneously heat and cool different zones of the building with disparate temperature conditions such as 12°C in the fish market and 25°C in the leisure zone.References: Smart CitiesReducing demand, integrating processes and optimizing generation, distribution and heating and cooling systems, in order to minimize primary energy and water consumption in existing systemsTOBEE - Multidimensional performance analysis of office buildings with glass facades. The TOBEE projects analyze the energetic and economic behavior and the comfort of office buildings in different environments of the Iberian peninsula, obtaining calibrated results that point to both energy problems and more efficient designs and solutions under a cost optimization perspective based on the 2010 EPBD. The study analyzes thousands of scenarios based on the matrix of types of facades, openings, orientations, shading elements and environments, lighting systems, generation and dissemination of heating and cooling and others. Each of the case studies have an associated dynamic mathematical simulation models that evaluates the energetic, economic, and comfort performance, hour by hour for a whole year. These tools have been previously calibrated with real data monitoring, infiltration tests, and audits of a number of representative reference buildings. The development procedure uses sensitivity analysis tools that statistically detect behavior patterns for sets of scenarios and specific cases. Thus, the analysis presents results and conclusions with the goal of identifying buildings with optimal costs and Net Zero Energy Buildings, in terms of the viability of these and associated cost overruns.Aiguasol, thanks to the interest shown by various public and private entities, has been able to increase the initial scope of the TOBEE project, increasing the initial environment from the Mediterranean climate to other peninsular climates (Continental and Atlantic), and analyzing not only case studies for new building development, but also the potential for rehabilitation. On the next page, find a list of buildings that have been studied under TOBEE in Madrid.25Telefónica Headquarters BuildingDla Headquarters BuildingIdom Headquarters BuildingOrtiz Headquarters BuildingOrtiz operated BuildingMetrovacesa BuildingEvaluation of the potential for solar heating and cooling in residential and service sector buildings in Spain.Photo: Solar cooling system in the Can Caralleu sports center in Barcelona (project for the Barcelona Energy Agency)The goal of the project is to establish the potential for cooling and heating using solar thermal energy in residential and service sector buildings in Spain. The study is one of the cornerstones making up the National Plan for Renewable Energy 2010-2020 of the IDAE, the Institute for Energy Diversification and Savings.The analysis includes different building typologies, single family residences, multi-family residences, hospitals, etc… using different scenarios to evaluate present and future thermal building regulations. The results are expressed in m2 of installable solar collectors, cost of renewable kWh generated, return on initial investment and percentage of assumable coverage of demand. Results are per province, autonomous community, building typology and generation technology.Study of the potential market and technical integration of geothermal systems in service sector buildings.Aiguasol carried out an analysis of the potential market for implementing geothermal systems in service sector buildings for Gas Natural Fenosa.The goal of the study was to determine under which scenarios it was economically and technically viable for Gas Natural Fenosa to install geothermal systems in the service sector and to determine the percentage of optimum coverage for geothermal systems and to determine hybridization with an auxiliary system.The study also developed business models to commercialize this type of system.26Barcelona Energy Improvement Plan (PMEB)In the framework of the Barcelona Energy Improvement Plan, Aiguasol was commissioned to evaluate the energy consumption in buildings, both residential and offices, and was able to evaluate up to 90% of the area with this kind of typology in the city of Barcelona.To undertake a study with the possibility of identifying specific measures, we did a typological classification of the buildings in the city according to their energy behavior. Later, we did a detailed study of the energy behavior of each of the building-types that were chosen, using dynamic simulation tools (TRNSYS), as well as incorporating specific data calculations relative to the conditions of use and the more common types of installations.In the baseline scenario we analyzed different savings packages at the citywide level, with an associated energy savings of 15%.Desarollo Urbanistico Chamartin (DUCH), district wide heating and cooling network27Desarollo Urbanistico Chamartin (DUCH) is a private company which is responsible for an urban development project for the Castellana area in the north of Madrid. The project is emblematic for various reasons, among which is its paradigm for urban sustainability, as it proposes a change in the conception of use in the contemporary city in three basic aspects: public transit, energy efficiency and water consumption.In the field of energy efficiency, DUCH contracted Aiguasol to do an in depth viability study on the potential for the construction of a district heating and cooling (DHC) network in the neighborhood.Aiguasol used methodologies for analyzing urban demand, using the neighborhood in a Sketch-up model, exporting it to TRNSYS and implementing the results in geographic software in order to visualize, hour by hour, the consumption for each parcel.The energy bill represents a growing percentage of manufacturing costs, minimizing this cost requires optimizing machinery, process integration and using renewable energyReferences: Industrial ProcessesMERCK- Thermal energy audit Thermal Solar System of 15,000m2 for AgrosuperTo optimize industrial thermal energy supply, a integral holistic focus is needed which incorporates:?? Possibilities of reducing demand by using heat recovery?? Process integration?? An intelligent combination of efficient heat production and technology to provide coolingThis kind of analysis requires the ability to study a large amount of data, expert knowledge and the calculation tools that few companies have. In this sense, Aiguasol carried out the energy audit with a focus on thermal consumption and identified and determined the main parameters for possible investment in the externalization of energy services. A basic engineering project to design a district heating network based on solar thermal energy for heating 19 pig farms (80,000 animals) in the Atacama region of Chile (Proyecto Freirina). 15,000m2 of collectors were planned for phase one with an additional 5,000m2 in phase two.In addition we designed a heat delivery system using radiant slabs and an auxiliary generation system using air-water heat pumps, the latter of which is now finished. The project is optimized so that the entire investment can be recuperated in less than five years.29The rising demand for cooling is one of the greatest current challenges and solar thermal or geothermal energy provide interesting solutionsReferences: Solar CoolingSolar cooling system in Can CaralleuThe Can Caralleu municipal sports center in Barcelona recently installed a solar cooling system which uses the heat captured by solar collectors to generate cooling through the process of absorption. This cold is used to control the ambient humidity for one of the pools in the center. Furthermore, the efficiency of the center was improved by using the rejected heat by the absorption chiller to heat the water in the pool, and the system is also able to generate domestic hot water (DHW).The final design significantly improved the habitual performance of the solar cooling systems.The project, as part of the “Plan for energy, climate change and air quality Barcelona 2011-2020” of the Barcelona city hall has been led by the Barcelona Energy Agency, with technical consultation by Aiguasol.Senior Citizens Residence in a highly energy efficient building in the former “Cibeles” in BarcelonaThe building, built by the Barcelona Municipal Housing Board (PHMB), received the highest energy rating and became the second residential building in Barcelona to get an “A”. The building is 5,086m2 and is part of the European Union High Combi project, which includes participation from Austria, Italy, Greece and Spain. As part of the project, solar thermal energy can be used to cover 60% of the total building demand, including DHW, heating and cooling. The system provides the housing with heating in the winter and cooling in the summer.31Nearly a quarter of Aiguasol’s resources are dedicated to research and development, including through participation in European projects or TASKS for the International Energy AgencyReferences: R&DAnalysis of Potentail of Solar Heat in Industrial Processes – POSHIPIn 2001, Aiguasol led the European POSHIP Project as laid out in the Fifth Framework Program of the European Commission’s Directorate General for Transport and Energy (DGTREN).POSHIP is a study of the potential application of solar heating for industrial processes in the Iberian Peninsula. Within this project we analyzed a representative sample of industries in Spain and Portugal, carrying out practical case studies of solar systems in industries presenting especially favorable conditions.In the first phase, the study analyzed different industrial sectors, identifying their processes and valuing the potential application of solar heating. In a second phase, we revised the existing technology in the market and compared their benefits for industrial processes. Finally, system design and economical evaluation considerations were presented, with real cases as well as dealing with the aspects for financing the projects.The study resulted in a potential installation for industrial plants with more than 25,000 m2 of solar thermal collectors and laid the foundation for solar heat for industrial processes for the European scientific community.33Photo: Industrial solar thermal system for preheating water at Parking Services Castellbisbal (European Solar Prize 2005).The fusion between theoretical and conceptual work with our job site experience gives us the know how to optimize systems in order to achieve the best economical and energetic performanceReferences: Solar ThermalHigh temperature thermosolar plant for a meatpacking companySince Februrary of 2012, Mafrica, a meatpacking company in Sant Joan de Vilatorrada (Bages), has a thermosolar plant to produce hot water that it uses in industrial processes. The plant is used under an ESCO agreement, such that Mafrica pays the service company for the heat it uses, which is the owner of the installation.Aiguasol participated from the initial phases of development of the Fresnel Linear Concentrator for the production of hot water at high temperature with the service company, Aira Termosolar. We also were responsible for integrating the new system with Mafrica.35Picornell Swimming Pools - Integration of solar thermal with pergolasThe Barcelona Energy Improvement Plan, as an Action Plan, integrated a set of 54 projects defined and specified at the environmental, energetic and economical level. The PICORNELL pool complex was identified as an ideal place to install a solar thermal system for domestic hot water, due to the large number of people using the pools daily as well as a high profile event which was the 2003 World Swimming Championship. AIGUASOL carried out the implementation and technical supervision of the project. In this unique project, we opted for a 334 m2 solar field built on a structure of pergolas in the parking lot for the swimming pools.Our daily use of simulation software gives us a high degree of quality in the development of software and customized applicationsReferences: SoftwareTRANSOL- Software for calculating solar thermal systemsThe first version of TRANSOL came out in 2004 and is a software tool for calculating and designing the solar thermal systems that we design. With the success of the first version, the following versions have been the result of an ambitious collaboration with the French research center CSTB (Centre Scientifique et Technique du Bâtiment). The second version hit the market in 2006 and TRANSOL 3 was launched at the end of 2009.TRANSOL is a tool for designing, calculating and optimizing solar thermal systems. TRANSOL makes dynamic simulation simple (TRNSYS engine) through a user-friendly interface. It incorporates weather data for the entire world and has an extensive database of solar collectors, storage tanks, insulation materials, etc. and provides detailed performance and economical reports. This tool comes from an ambitious project carried out by Aiguasol in collaboration with the French research center CSTB (Centre Scientifique et Technique du Bâtiment).TRANSOL has an intuitive and high quality graphic interface brings the user the reliability and precise dynamic calculations of the well known TRNSYS program (TRaNsient simulation SYStems) and is used to calculate, design and optimize solar thermal systems.TRANSOL is intended for installers, small and medium engineering and architecture firms and for energy planners. TRANSOL is already used by energy agencies all over Spain to design and control the quality of solar thermal installations. At the same time, Aiguasol facilitates training at Universities and training centers by offering TRANSOL at special education rates.TRANSOL 3.2 represents an important advance from previous editions. The new version incorporates improvements in calculation and performance, as well as a large number of new features which include a global climate database, calculation for solar cooling, the application of solar heating in industrial processes and the parameterization of cases, 37Software to choose MADEL products for heating and cooling installationsDevelopment of a methodology to certify the energy efficiency of microgeneration systems.Aiguasol developed an intuitive software program to pre-plan the heating and cooling installation using air diffusers manufactured by MADEL. The software is based on the diffusion and acoustic behavior curves of the components.The software includes a complete product selection program, facilitating installation design and provid-ing simulations of the air diffusion and acoustics. With the program you can print a technical report with information on the selected product.38Aiguasol has developed a calculation methodology and a tool that will allow for the introduction of microgeneration systems in the Spanish protocol for energy efficient building certification. This was done for the Spanish COGEN association in order to help overcome the lack of an easy and generalized way to certify microgeneration systems for housing and the small size tertiary sector buildings and the barrier that this represents for market penetration,. The methodology has been submitted to become a Recognized Document and form part of the Spanish legal regulations.39Development of solar thermal energy software for BOSCH, based on CHEQ4Development of CHEQ4 for the IDAE, official tool for verifying solar thermal systems in SpainAs previously mentioned, Aiguasol developed CHEQ4 for the IDAE within the context of the new regulatory framework governing minimum solar energy contributions for domes-tic hot water.In this context, the BOSCH Group was interested in the development of a commercial tool, based on the calculation methodology incorporated in CHEQ4 (METASOL). However, the only wanted to include their commercial products, with some additional options and the generation of a personal-ized report along with the corporate image of the BOSCH/Buderus group.As you can see, Aiguasol has the capacity to develop customized calculation tools to solve energy problems.Aiguasol developed CHEQ4 for the IDAE (Institute for Diversification and Energy Savings) and ASIT (Solar Association of the Thermal Industry). CHEQ4 is a software program that allows any agent in the low temperature solar thermal energy sector to apply, comply with and evaluate section HE4, including the HE Savings regulation as laid out in the Technical Building Code (CTE).The tool aims to facilitate the compliance with regulations by all agents working in the solar thermal sector, as well as promote a standard calculation method that combines precision with ease of use.CHEQ4 is based on the METASOL calculation methodology also developed by Aiguasol.Some of our customersCustomers41Scientific Publications by the Aiguasol teamPublications2012Evaluation of air leakage and its influence on thermal demands in Madrid’s office buildings.
