Building automation is the automatic centralized control of a building's heating, ventilation and air conditioning, lighting and other systems through a building management system or building automation system (BAS). The objectives of building automation are improved occupant comfort, efficient operation of building systems, reduction in energy consumption and operating costs, and improved life cycle of utilities. Building automation is an example of a distributed control system – the computer networking of electronic devices designed to monitor and control the mechanical, security, fire and flood safety, lighting (especially emergency lighting), HVAC and humidity control and ventilation systems in a building.[1][2] BAS core functionality keeps building climate within a specified range, provides light to rooms based on an occupancy schedule (in the absence of overt switches to the contrary), monitors performance and device failures in all systems, and provides malfunction alarms to building maintenance staff. A BAS should reduce building energy and maintenance costs compared to a non-controlled building. Most commercial, institutional, and industrial buildings built after 2000 include a BAS. Many older buildings have been retrofitted with a new BAS, typically financed through energy and insurance savings, and other savings associated with pre-emptive maintenance and fault detection.

Hypertext Markup Language (HTML) is the standard markup language for creating web pages and web applications. There are several articles that list some important upcoming features of HTML5, which can work on certain browsers. This tutorial for the web developer will show you how you can use certain features of HTML 5
HTML 5 features
Web Workers: Certain web applications use heavy scripts to perform functions. Web Workers use separate background threads for processing and it does not effect the performance of a web page.
Video: You can embed video without third-party proprietary plug-ins or codec. Video becomes as easy as embedding an image.
Canvas: This feature allows a web developer to render graphics on the fly. As with video, there is no need for a plug in.
Application caches: Web pages will start storing more and more information locally on the visitor's computer. It works like cookies, but where cookies are small, the new feature allows for much larger files. Google Gears is an excellent example of this in action.
Geolocation: Best known for use on mobile devices, geolocation is coming with HTML5

The latest version of Cascade Style Sheets, CSS 3, was developed to make Web design easier but it became a hot topic for a while because not all browsers supported it. However, trends change quickly in technology and all browser makers currently are implementing complete CSS 3 support. Making that process easier for the browser manufacturers is CSS 3's modularized specification, which allows them to provide support for modules incrementally without having to perform major refactoring of the browsers' codebases. The modularization concept not only makes the process of approving individual CSS 3 modules easier and faster, but it also makes documenting the spec easier.

CSS3 Features
Selectors : CSS 3 introduces some new selectors. Using these selectors you can choose DOM elements based on their attributes. So you don't need to specify classes and IDs for every element. Instead, you can utilize the attribute field to style them.
Rounded Corners : CSS 3 addresses this problem by introducing the border-radius property, which gives you the same rounded-corner effect and you don't have to write all the code. Here are examples for displaying rounded corners in different places of a website.
Text/Box Shadow : The new text-shadow property allows you to add drop shadows to the text on a webpage. Prior to CSS 3, this would be done by either using an image or duplicating a text element and then positioning it. A similar property called box-shadow is also available in CSS 3. A box shadow allows you to create a drop shadow for an element. Usually this effect is achieved using a repeated image around the element. However, with the property box-shadow this can be achieved by writing a single line of CSS code.
