Alabama HVAC/Refrigeration License and Exam

The IRC contains many important changes such as:

• An updated seismic map reflects the most conservative Seismic Design Category (SDC) based on any soil type and a new map reflects less conservative SDCs when Site Class A, B or D is applicable.
• The townhouse separation provisions now include options for using two separate fire-resistant-rated walls or a common wall.
• An emergency escape and rescue opening is no longer required in basement sleeping rooms where the dwelling has an automatic fire sprinkler system and the basement has a second means of egress or an emergency escape opening.
• The exemption for interconnection of smoke alarms in existing areas has been deleted.
• New girder/header tables have been revised to incorporate the use of #2 Southern Pine in lieu of #1 Southern Pine.
• New tables address alternative wood stud heights and the required number of full height studs in high wind areas.

Manual D includes a number of informative appendices related to air distribution systems (e.g., equipment and air-side components, controlling excess air when VAV dampers close, duct loads, duct leakage and duct system efficiency, air quality issues, noise control, minimum air velocity for ducts; codes, standards and best practice issues; and commissioning issues). The Manual D has been significantly revised to include:

• Updated and expanded VAV guidance, with detailed examples
• Impacts of excess length, sag and compression in flexible ducts
• New equivalent length values for flex duct junction boxes

Manual D provides:

• A single set of ANSI-recognized duct sizing principles and calculations that apply to all duct materials
• System operating point (supply Cfm and external static pressure), and airway sizing for single-speed and multi-speed (ECM) blowers
• A method for determining the impact of duct friction and fitting pressure drop on blower performance and air delivery
• The most comprehensive equivalent length data ever published

You can apply the Manual D procedure to constant volume systems and zoned variable air volume systems, over a full range of duct construction materials. Manual D includes a number of informative appendices related to air distribution systems (e.g., equipment and air-side components, controlling excess air when VAV dampers close, duct loads, duct leakage and duct system efficiency, air quality issues, noise control, minimum air velocity for ducts; codes, standards and best practice issues; and commissioning issues).

MJ8AE, an abridged version of the Eighth Edition of Manual J, provides complete instructions for estimating heat loss and heat gain for residential structures. MJ8AE is sufficient for learning the Manual J procedures and for undertaking hand calculations on a varied number of home applications.

The NASCLA Contractors Guide to Business, Law and Project Management is organized into three sections.

Part 1 focuses on planning and starting your business. This section will help you formulate a business plan, choose a business structure, understand licensing and insurance requirements and gain basic management and marketing skills.

Part 2 covers fundamentals you will need to know in order to operate a successful construction business. This section covers estimating, contract management, scheduling, project management, safety and environmental responsibilities, and building good relationships with employees, subcontractors, and customers.

Part 3 provides valuable information to assist you in running the administrative functions of your business. Financial management, tax basics, and lien laws are covered. Effective management of these areas of business is vital and can cause you serious problems if you do not give them proper attention.
