One of the first such missions has now begun, led by Andre Filiatrault, PhD, University of Buffalo professor of civil, structural and environmental engineering and director of the Multidisciplinary Center for Earthquake Engineering Research (MCEER), headquartered at UB. Filiatrault is working in partnership with Appropriate Infrastructure Development Group (AIDG), a national organization that helps provide developing countries with affordable renewable energy, sanitation and clean water. Filiatrault together with a team of 10 architects and engineers from U.S. educational institutions and private engineering firms will embark on a mission to determine which of Haiti's most critical structures - particularly its hospitals and ports - are safe to enter, and which pose a danger.

It mandates the inspection of energy systems by local officials to ensure that heaters, air conditioners and other mechanical equipment in nonresidential buildings are working efficiently. And it will allow local jurisdictions, such as San Francisco, to retain their stricter existing green building standards, or adopt more stringent versions of the state code if they choose. "This is (something) no other state in the country has done - integrating green construction practices into the very fabric of the construction code," said Tom Sheehy, acting secretary of the state Consumer Services Agency and chair of the California Building Standards Commission, which approved the standards. "These are simple, cost-effective green practices. ... California should be proud."

You were a pleasure to work with and thank you for letting me participate in the design process. You were so kind and patient when I suggested bad designs and then skillfully lead me to a new vision of what could be. Your design will save me a lot of money and a lot of my time building this structure. Phil Barry, I am very happy with my new building plans.

In this webcast, Dru Crawley, leader of the Department of Commercial Building Initiative of the U.S. Department of Energy, will discuss how his organization is leveraging modern technology to improve building performance. In addition, Noah Eckhouse of Bentley Systems will explore how industry-leading energy design, simulation, and analysis software applications are providing today's professionals with the necessary tools to effectively optimize the balance of function, comfort, and energy and carbon impact and help building teams sustain our environment. Both presenters will share a number of real-world design scenarios explored and validated, and discuss the realized benefits. Summary:

I'm so pleased to have my impression of you confirmed by people that have already worked with you. Talk to you tomorrow after we see the what's going on under the house. I'm looking forward to working with you. Sunni Hi Barry,

Just want to let you know I spoke to Paul Wang tonight…..he raved about you, how creative you are and nice to work with as did Gary.

I’m so pleased to have my impression of you confirmed by people that have already worked with you.

Talk to you tomorrow after we see the what’s going on under the house.

I’m looking forward to working with you.

Are you a Code Official? What you are seeing are 3" PVC pipes going through 2x10 sawn lumber joists of the second floor. (30lb live load) How did you determine that the design was for 30#psf.? The joist spans are 13' 6" and the bores occur in the exact middle of the joists (top to botttom) and in the end 3rd of the joist spans nearest the exterior bearing wall. 2"x10" joist is good to span 19'1". Assumming your 30# load and a 10# dead load that you did not mention. The bored hole sizes were 4 1/2" in diameter. The outside diameter of 3" PVC pipe is ~3 1/8". Is there anything wrong with this construction? Any Code Violations? Your question would be answered as yes, and no. Per R502.8 the maximum hole size could not have been any greater than 3 & 11/64"s, so yes it is in violation. Since it has been reinforced as shown, the IRC does not reflect that and in my opinion, based on the capacity of these floor joist, I would not be worried. This is only my opinion.
