New Electrical Code Effective June 6, 2009 Electrical projects related to a Seattle building permit will be regulated by the electrical code that was in effect on the date the building permit application was submitted. Every three years the National Electrical Code is updated. Seattle then reviews and adopts the NEC with state and local amendments. The Seattle Electrical Code Supplement and National Electrical Code will be available the week of May 26 at DPD’s Public Resource Center on the 20th floor of the Seattle Municipal Tower. For information regarding the availability of publications at DPD, please call (206) 684-8467. The code will also be available online on the DPD codes web page. DPD staff suggests that if users of the electrical code have not attended a 2008 National Electrical Code Update class, they should do so at their earliest convenience. |
The new electrical code takes effect on June 6, 2009. |

New Green Building Publication on Natural Ventilation What is Natural Ventilation? Natural ventilation is the use of a building’s form, organization, and openings in conjunction with naturally occurring phenomenon, such as the wind or warm air buoyancy, to supply air to its occupants and to remove heat from both the occupants and the building. Forms of natural ventilation activated by the forces of gravity are called stack ventilation. Wind-driven systems are referred to as cross ventilation. Natural ventilation is used for:
Why Should Buildings be Naturally Ventilated?
Types of Natural Ventilation Systems that primarily rely on gravity are called stack ventilation. Stack ventilation through a space is a function of the vertical distance between inlets and outlets, their size, and the temperature difference between the outside air and the average temperature in the stack. Wind-driven systems are referred to as cross ventilation. Cross ventilation airflow through a space is dependent on opening size, wind speed and direction, building shape, and opening location. Cross and stack ventilation can work together. If the inlets for stack ventilation correspond to the high-pressure zones and the outlets to the low-pressure zones, then wind will assist the stack ventilation.

| Green CAMs Have a New Number That’s right Seattle, green isn’t separate; it’s how we do things today. Green CAMs will now appear within the CAM series categories. The CAMs will still be green and you can find them where you normally look for information on building practices. |
![]() Green CAMs have been integrated with the rest of the DPD CAM series. |

Submit Your Question to a Land Use Planner Online For specific land use questions on sites proposed for development or for complex questions, we recommend that applicants visit the ASC and speak with a land use planner in person. The more you know about your specific property and situation before you arrive, the quicker your visit will likely be. Wait times to speak with a land use planner in the ASC can be an hour or more during peak hours (10 a.m. to 5 p.m.). DPD provides free wireless Internet access and self-serve computers to make your wait more productive. |
