In buildings, you really can’t manage heat without also managing moisture. For example, if you increase how much insulation is in a wall, you may also be increasing the risk of moisture and mold problems.</p> <p>There are four ways that buildings can get wet:</p> <ul> <li>bulk water leaks (rain dripping through a hole in your roof)</li> <li>wicking (groundwater being pulled up through a concrete foundation)</li> <li>air leaks (condensation inside a wall assembly)</li> <li>vapor diffusion (high interior relative humidity in the winter; high exterior relative humidity in the summer)</li> </ul> <p>&nbsp;And there are just three ways they can dry when they get wet:</p> <ul> <li>drainage (intentional spaces between building components)</li> <li>air flow (convective drying, like your hair dryer)</li> <li>evaporation (low relative humidity and adding the sun for drying)</li> </ul> <p>Frankly, four against three can add up to less than the greatest odds for drying.</p> <p><a href="http://www2.buildinggreen.com/blogs/what-hygrothermal-building-assessment" target="_blank">read more</a></p> BuildingGreen's Top Stories http://www2.buildinggreen.com/blogs/what-hygrothermal-building-assessment#comments Wed, 29 Apr 2015 15:06:01 +0000 Paula Melton 21926 at http://www2.buildinggreen.com Leaders in Sustainable Design Speaking at AIA Convention 2015 http://www2.buildinggreen.com/blogs/leaders-sustainable-design-speaking-aia-convention-2015 <div class="field field-type-text field-field-bg-blog-author-name"> <div class="field-label">Author name:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> Alana Fichman </div> </div> </div> <div class="field field-type-text field-field-bg-blog-category"> <div class="field-label">Blog Category:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> BuildingGreen's Top Stories </div> <div class="field-item even"> AIA Convention </div> </div> </div> <h3 dir="ltr">Looking for the greenest updates at Convention this year?

But if you are looking for the greenest talks of them all, look no further! Many of today’s greatest minds in sustainable design will be sharing their stuff—with everything from specifying healthier building materials to the latest on resilient design leadership to geeking out on energy modeling.</p> <p dir="ltr">Don’t see your sustainability-related session here?

At that time, BuildingGreen partnered with BAC to help design the curriculum, find the best instructors available, and promote the courses being offered.</p> <p>Early on, when we had just a handful of courses, I taught <em>Sustainable Design as a Way of Thinking</em>, a course now being ably taught by my friend David Foley. Today, the online offerings totaling almost 20 courses are housed in BAC’s Sustainable Design Institute.</p> <p><a href="http://www2.buildinggreen.com/blogs/learn-sustainable-design-without-having-brave-cold-and-snow" target="_blank">read more</a></p> BuildingGreen's Top Stories Energy Solutions http://www2.buildinggreen.com/blogs/learn-sustainable-design-without-having-brave-cold-and-snow#comments Mon, 02 Mar 2015 20:33:57 +0000 Paula Melton 21312 at http://www2.buildinggreen.com Have You Been Conflating Water with Energy?

Yet the time and attention that we devote to water remains a fraction of that we allot to energy.</p> <p>I think that the problem is that we tend to talk about water conservation and efficiency as if water is just a clone of energy. Water and energy are similar in many ways, but there are key differences; until we appreciate these differences and embrace water on its own terms, we’ll continue to dis it.</p> <p>Here are the five key differences that are confusing our approach:</p> <p><a href="http://www2.buildinggreen.com/blogs/have-you-been-conflating-water-energy-here-are-5-reasons-stop" target="_blank">read more</a></p> BuildingGreen's Top Stories http://www2.buildinggreen.com/blogs/have-you-been-conflating-water-energy-here-are-5-reasons-stop#comments Mon, 02 Mar 2015 15:02:46 +0000 Paula Melton 21311 at http://www2.buildinggreen.com
