Energy-savingbuildings, as well as many other solutions that are becoming more and morepopular, are the result of those first studies, which have been deepenedthrough the decades.

One of thefirst fields of study of sustainable architecture, which can been defined asthe discipline that is aimed at building trying to maintain the balance betweenthe wellbeing of people and the health of surrounding nature, was that ofrenewable energy sources, alternative to oil, like solar energy. The firstexamples of green buildings, which appeared in Europe and in the States in theEighties, highlighted the attempt of searching for new methods to produce andnot to disperse energy. With the passing of time this trend and the studies inthis field have been deepened, while environmental problems, which arewell-known by us all but seem to be impossible to be solved, have become moreserious. Terms like external wall insulation, dehumidification, natural light have become part of the vocabulary of architecture and construction, and havebegun to be used to describe new types of houses and buildings.

Sustainablearchitecture includes many sectors, from building materials to designing, fromenergy sources research to the insulation of buildings. As far as buildingmaterials is concerned, sustainable architecture is meant to use highperformances, low environmental impact materials, which are not too expensive.This means avoiding to use materials that can be dangerous for our health, likechemical glues and paints, and replacing them with natural materials. Choosingmaterials for green buildings also means limiting the use of resources, perhapsusing recycled or light materials, which can be more easily transported. As faras the designing stage is concerned, sustainable architecture is very focusedon environmental impact, and tries not to change the habitat where the buildingwill be built. First of all, architects need to consider the location of thebuilding, which should be able to benefit from solar light and otheratmospheric factors. Secondly, green buildings are meant to maintain thenatural peculiarities of the place where they will rise, which also implies afocus on landscape projecting. As for energy sources, it is self-evident thatgreen buildings are focused on energy saving. This results in a higherattention on alternative and renewable energy sources (in this sense solar andphotovoltaic panels play an important role), but it also means using householdappliances that consume less and studying some methods to avoid dispersingenergy. In this sense, it is very useful to insulate buildings, using specialwalls, windows and doors that limit heat loss and the use of air conditionersand heating systems, which enormously contribute to air pollution.

If we allfollowed all of these and other principles of sustainable architecture, theadvantages for the environment, as well as for our health and for our wallet,would be numberless.

The Power of Appreciation

Is there anything more mysterious in theworld than the formula to having a successful romantic relationship? Asa divorced woman, I now marvel at those who are able to createpassionate, loving, long-term relationships. From my studies with booksand the school of hard knocks, I believe that one of the most importantingredients in relationships, of all kinds, is appreciation. What is Appreciation? Appreciation is likea much-needed rainfall to a farmer's crops that have been withering ina drought. Just as the crops start to shrivel and die without water,human relationships also start to feel brittle without a steadyapplication of the nourishing, even life-giving, impacts ofappreciation. The dictionary defines appreciation as "a favorablecritical estimate," "sensitive awareness" and "an expression ofadmiration, approval or gratitude." When you appreciate someone, youare tuned into a positive quality of another human being and expressyour gratitude for it. ...

Corporate ERP on Dynamics AX Deployment with Hub and Spokes Architecture

In certain business development scenarios you, as IT director of mid-market company have to respect existing structure and plan the evolution. This is especially true when your company expands in the way of acquisitions. Additional complication might be attributed to international business model, where you are acquiring established enterprise in the foreign country. In this small paper we would like to come through some popular theories and recommendations, where we suppose that you have Dynamics AX or formerly known as Axapta in your headquarters. If you are in Corporate ERP selection mode, we recommend you to consider AX in the case, when your policy is leaning toward Microsoft Dynamics products and technologies: 1.Why AX? First of all this ERP and MRP platform is recommended by Microsoft for the implementations in such industries as meat, fish and sea products, poultry, mining and oil drilling, distribution and logistics and with new version 2012 in public sector (GL fund managemen...

Attic Fans

Attic and roof ventilation allows excess heat and moisture to escape at home to reduce summer cooling costs, pre-mature deterioration of roofing materials and condensation can lead to costly repairs. Effective attic ventilation relies on natural convection to pull air from the top to the bottom position, often in the open in Sofia, and the exhaust hot air from the ceiling vent in a higher position, such as through a gable, or open. Many new and existing homes are not ceilings, and its architecture can not afford soffits perforations for ventilation. While most households are conscious on the convenience brought by nicely ventilated homes, many tend to overlook the attic as one of the areas to be considered. No one finds it comfortable staying for long hours in the closed attic because of the overwhelming heat that builds up in it. For this reason, it is necessary for everyone to consider installing attic ventilation fans in order to cool down the attic's heat. This can have amazin...
