2 Energy management via the Internet
Only by keeping a continuous record and analysis of energy consumption data is it
possible to identify potential savings and evaluate the success of optimization
measures.
By highlighting external influencing factors (weather compensation) and making
comparisons with defined set points (target energy figures), EMC helps customers
make reliable judgments about the consumption of energy.
2.1 Functionality
EMC is based on ASP (Application Service Providing) technology. The consump-
tion data is logged on a central Siemens Internet server, under a secure personal
user account. The consumption data is logged either manually via a standard Web
browser, or automatically. EMC can be operated and reports can be invoked from
any standard PC with Internet access (preferably with Internet Explorer) as illus-
trated below.
Application Service Providing (ASP) is the official term for applications which are
made available by a service provider over the Internet rather than being provided
locally.
There are numerous advantages to ASP:
• Cost-savings in relation to local hardware and software
• Updates and upgrades are free of charge when using this service
• Customers can access their own data from anywhere and at any time
• Running the applications in a professional data center ensures minimal down-
time and a high degree of security
• The content of the customer's applications remains confidential, because the
Application Service Provider only supplies the professional infrastructure.
• All saved data are the property of the customer.
