System selections are defined according a priority-scoring matrix, which is based on the building concept and the Client requirements. The most suitable system in each case defines since several criteria.

Usually heat and electricity are the main sources of energy within the building and therefore several profiles are created primarily, and converted by energy balance.

The required energy in the building calculates approximately hour-by-hour and day-by-day.

In most cases with regards to buildings, the source of electricity is expected from the National Grids. However, there are buildings that require or simply desire to be independent in terms of its required source of energy. To operate a building of that specification, it must be estimated by ap propriate plant design, which will ensure that the building will run in accordance to its energy conditions. The profiles are essential, in the process of encoding and designing the systems to be adaptive to the building consumptions.

As the energy consumption, a carbon emission profile is created for a building that needs to be environmentally conscious. This will help the building to gain credits for some accreditations such as LEED, BREAM etc. In addition, some countries subsidy the carbon dioxide saving for each year.

A detailed analysis can outline which systems or services are the most adequate when considering any financial constraints. Some criteria are defined by the Clients according to their limitations and concepts such as Payback Periods, Net Present Values and Internal Rates of Return.

A Sensitivity analysis is inclusive in our service should any specific cases arise. This is a “what if” study whereby certain variables can be analyzed in terms of their effects on the overall budget of the project. This analysis is useful in the sense that a solution to a potential problem is considered in great detail by varying the values of some parameters or changing some assumptions when faced with change in rates such as the NPV.
