HTML5 will help Building Automation System interfaces create a more consistent and powerful user experience. The new components available and the ability to incorporate new JAVA, .net and flash objects without having to load client side software will make writing web interfaces more efficient and create a unified solution that will adapt based on the browser.

The new Canvas API will create a 2D render space for objects that can provide advanced user interface components like those from Sencha, Mootools and Jquery. This space can also be used to create dynamic objects to represent real time values and allow the user to interact with the content.

Similarly the SVG API will allow content to be dynamically displayed with such capability it will rival a desktop application for performance and functionality. Imagine interactive animated graphics updating in real time with dynamic data without needing server side interactivity.

The Web Storage API can make it possible to store more data locally enabling localization of some functions and settings and local user query results. A user monitoring certain areas of a facility and certain analytical data might be able to store their current settings, dashboard configuration and data views locally so that they can "pick up where they left off" later.

The Web Worker API will allow updating of values, conditions and analytical operations running in the background and keeping the browser responsive to the users input and other functions. Data polling might eventually be able to happen at the browser level and eliminate the need for "middleware".

The next major focus of energy management will likely concentrate more on analytics, measuring performance and adjusting sequences and schemes to adapt to demand and energy costs. This will require that data be instantly accessible and easy to navigate from any platform. HTML5 promises to simplify the interface to multiple platforms with a uniform look, feel and performance. This will enable rich data content and analytical capability. With so much new functionality becoming part of the browser and not relying on third party add-in components the application designers will have more capability on the client side of the web.
