Managing the Biggest Building Challenge – Moisture

We have reached the dessert portion of The Art of Building Science webinar series and it is definitely apple pie a la mode because it is jammed packed with information. A large portion of this session is focused on Moisture Management because that is the number one cause of premature service life in our built environment today. It is the one thing that we never, ever find a way to live with.

Moisture management is critical to everywhere we build because we build with water and water surrounds us. I have taken part in mold remediation projects in East Los Angeles so even in drought-ridden California you can experience excessive moisture at times. The only place on the planet that does not have moisture issues ever (at least for a very long time now) is the Atacama Desert in Chile.

Even if you haven’t been able to participate in the earlier sessions, join us Tuesday, May 6 at 5:30 pm EST. Of all the topics we cover in building science, moisture management seems to generate the most questions and the most confusion so it’s always a good time to refresh our memory and augment our knowledge. You can register right here for The Art of Building Science Part III – Moisture Flow. This course is AIA approved for 2 CEUs.

As we continue to see devastating weather systems throughout the US, designing and building to manage moisture is becoming increasingly important. Don’t miss this opportunity to learn more about controlling moisture in the built environment.

Don’t Risk Missing Points in LEED V4

LEEDv4If I put on my promotion hat on for a minute, I urge anyone using LEED to be aware of the transparency reporting changes between LEED 2009 and LEED V4. Both reward transparency points but in LEED 2009 they are found under the pilot libraries but in LEED V4 they are migrated down to materials and resources credits.

Since both programs will be in play until mid- 2015, it is important to know where to properly apply these transparency points from manufacturers that provide transparency documentation.

You can be awarded up to six points for transparency so, believe me, this is not something that you want to walk past these because it can cost you a fortune to make up six points somewhere else.

If you need to know the differences between LEED 2009 and LEED V4, I am running a webinar entitled Understanding LEED 2009 v. LEED Version 4on Tuesday, May 6 at 2:00 pm EST. My webinars are free of charge and qualify for AIA and GBCI credits.

In the spirit of transparency, I will cover the following objectives:

  • Identify key improvements in LEED version 4 compared to LEED 2009. Describe new credits applicable to building products and their requirements
  • Understand the new importance of products with Environmental Product Declarations (EPDs), Health Product Declarations (HPDs), and Extended Producer Responsibility (EPR) programs
  •  Identify products that improve energy performance, acoustics, daylight, waste management, and thermal comfort
  • Explain the importance of selecting low emitting products and materials to meet updated credit requirements

If you build for LEED, you won’t want to miss this session.

Tips for Checking for Mold Following a Wet Winter

Mold-in-basement2

Following this incredibly wet winter, it is a good idea to check to make sure that mold growth is not beginning inside or on your home. You may have noticed that the media has been talking about this on news programs of late.

Mold needs four things to thrive and liquid water is perhaps the most critical as it is the only one we have a chance of controlling. Having liquid water coupled with available oxygen, food and the temperature sweet spot, 41° to 104° F, is the perfect storm for mold growth. Here is what you should do:

  • Inspect your basement for damp walls or cracks where moisture can come in and seal them.
  • Fix plumbing leaks and other water problems as soon as possible. Dry all items completely. 
  • Scrub mold off hard non-porous surfaces with detergent and water, and dry completely.
  • On porous surfaces, in addition to surface cleaning you need to completely dry the material in order to prevent its reappearance. If that can’t be done, you may need to remove the material.
  • Inspect the exterior of your home at ground level. If water is collecting there, divert it away from the foundation.
  • If you find mold, make sure to cover your face and hands to minimize exposure when cleaning the area. It is also important to put a fan in a window and blow air from the room out of the house when you are working around the mold or you may disturb it. If it is a significant area affected or if you begin to feel “allergy type” symptoms when working around mold, call an expert to clean it out.

What humans typically react to are the mold spores which become airborne when it is in its “happy place” with food, water, and a cozy temp or when the mold is physically disturbed.  

We’ve made a lot of changes to how we build in recent years in order to conserve energy and live more sustainably. Many of the things we’ve done to improve our habitat have unfortunately created an ideal environment for mold to thrive. The only chance we have to keep mold from becoming a full-time member of our households is to eliminate the presence of liquid water in or on the materials we use to construct the dwellings.

 

Spray Polyurethane Foam for Building Insulation Webinar

I was just reviewing plans for a YouthBuild USA project that together we will be renovating in Worchester, MA this year and I was struck by the reality that even in a rehab like this, we don’t use the same methods or systems for insulating that we traditionally have used.

Spray foam insulationWhen we insulate new or existing structures today there is no ‘one size fits all’. There is no one material that can be used in all places in a cost conscious manner. To be efficient and effective, we need to combine materials. One product that we reach for to control air leakiness in colder climates is spray foam insulation.

It’s important to understand the properties of spray foam if you are going to use them as part of a combined system to achieve the required performance. Before you choose a spray foam, get familiar with the material and how to combine it with other insulation products so that you can control heat flow without causing other problems.

If you are interested in learning more about spray foam insulations, I am conducting a webinar on this subject on Wednesday, April 23 from 3:00 – 4:00 PM EST. You can register right here. And this course qualifies for CEUs!

You will leave this webinar with the knowledge to:

  • Understand Polyurethanes Background – The History of Spray Foam Insulation -Insulation Applications
  • Compare the Differences of Spray Polyurethane Foam Insulation -Market Trends / Energy Efficiency Demands -SPF Overview -Open Cell / Closed Cell –Properties
  • Review Building Envelope Considerations
  • Distinguish the Differences Between Residential and Commercial Building Applications

Bring your questions – I will be ready!

 

The Art of Building Science Part II Webinar

Building Science fans, it’s time for Part II of the three part series on The Art of Building Science.  I hope that if you participated in the discussion last month on Heat Flow that you will join me for the next part of the series which will concentrate on Air Flow. If were not able to attend the first session that is not a problem.  These topics work collectively and individually.

The webinar will take place on Tuesday, April 8 from 5:30 – 7:00 pm EST to accommodate attendees who cannot participate during regular business hours.

I like to think of this as the second course of a three course meal. The webinar will run for 90 minutes so that we can consume the entrée part of this three course meal which is packed with valuable information and insight. We can’t eat the dessert until we finish the entrée.

Part II features a more in depth discussion on Air Flow and will provide you a deeper understanding of building science.  This session is approved for 1.5 AIA CEUs.

Register now, right here for The Art of Building Science Part II – Air Flow.

I look forward to continuing the dialogue on The Art of Building Science.

Understanding and Improving Indoor Air Quality Webinar

We, as a society, spend 90 percent of our time indoors. It is extremely important that the air inside our buildings, both residential and commercial, is providing the healthiest environment possible.

I will be hosting a webinar on Tuesday, April 8 from 3:00 – 4:00 pm EST on the topic of Understanding and Improving Air Quality.

This is a newly accredited program for us taking a deeper dive into the topic which is touched upon in other webinars that we have offer.  It is a more focused discussion on how to improve indoor air quality. 

We have talked about this topic and provided education on what indoor air quality is but this program will identify actual steps that can be taken to improve the quality of indoor air.

Let’s get together – inside – and explore the ways to improve our indoor air.  You can sign up right here for the webinar Understanding and Improving Indoor Air Quality (IAQ) – (GBCI Approved).

Come with questions and try to stump the presenter!

Tips for Inspecting Low or Steep Slope Roofing Systems

Two of the things you should do every spring and fall are clean your gutters and inspect your roof.  Whether it is a steep slope or low slope roof you need to get up close and inspect for any defects or damage to the roof system.  If you have the safety equipment and training then get up there  and do it but if you don’t, call your roofer and schedule a time for them to take a closer look for you.

This has been a rough winter – record snow and record cold in most parts of the country.  From the additional deflections that have occurred under that snow load to the extreme expansion and contractions that have taken place due to the wild temperature swings, our roofing systems have undergone more wear and tear than usual. 

So, before those legendary April showers begin, make sure your roof drainage is open and not blocked.  While you have someone up there, look for problems, look for failures, and look at where things meet and in the corners. A little bit of maintenance NOW can prevent a lot of tear-off later.

I will be presenting a webinar on Wednesday, March 26, at 2:00 pm EST on the topic of Self Adhering Membrane Roof Systems.  There are many types of systems with new techniques and products to make maintenance and replacement much easier and cost effective.

If you are in need of updated techniques and tips for your roofing systems, please join me for the webinar.

The Sound Around You

HIPHN_El Paso Corp_Cafe_1_2000Improving acoustical performance in interior spaces is part of our everyday discussion, and raising awareness of the impact of noise on people has become a leading passion of mine. In the architectural and building industries, research provides clear evidence that exposure to noise impacts healing and productivity. This research influences how we design buildings for the people who spend the majority of their time in these places — the students in a classroom, patients in a hospital, or employees in an office. However at a personal, individual level, there is great value in better understanding acoustics in our daily lives.

Most interior environments should be safeguarded against decibel levels that would harm your ability to hear, however, how does excessive noise affect your ability to concentrate and overall stress level?

Measuring the decibel level of activities throughout the day is quite easy to do by simply installing a mobile app on your smartphone, such as Decibel 10th. I encourage you to use one of these tools to monitor fluctuations in the noise around you throughout the day and take note of how you respond. Do your muscles tense while struggling to have a conversation in a loud restaurant (or does your dinner-mate wonder why you are screaming at them over a simple decision as to what wine to select)? Are you more focused at work wearing sound-canceling headphones or “squatting” in an unoccupied conference room?

As you experience different noise levels, take note of how the sounds around you measure up to these average decibel levels:

Decibel Level (dB) Activity
0 Threshold of what a healthy ear can hear
10 Soft wind
20 A peaceful apartment in the city
25-35 Leaves rustling in the wind
40 Typing on a keyboard
50 Talking in a low voice
60 Conversation
65 Sitting in a small car with motor idling; normal office noise
75-90 Traffic noise

Taking an inventory of excessive noise in our daily lives is the first step toward a more productive and healthy society. For example, a study by the Danish Cancer Society that monitored the effect of traffic noise reports that for every 10-decibel increase, the risk of heart attack went up 12 percent with increases in risk starting at only 40dB. This is one statistic of many that are shedding light on the impact of noise in our lives. How does excessive noise or poor acoustics impact your daily life?

The Art of Building Science – Soup to Nuts Webinar Series

We are trying something new that we hope is helpful for those of you who would like to take a deeper dive into Building Science but can’t take time out of a nutty work day to do so.

Because I live Building Science every day, I occasionally lose sight of the fact that not everyone sees how all of this information works and fits together.  Sadly we live in a bullet point world so let’s give the big picture the opportunity to talk. Let’s give the silent masses the opportunity to ask questions and engage with folks who work with this knowledge on a daily basis in real world scenarios.

The early evening timeframe for this series may have particular value for younger architects and building professionals who do not get to take time out of billable hours but could jump online at the end of the day.

We are offering the opportunity to see the Big Picture of Building Science through a series of three webinars starting at 5:30 pm EST over the next three months that will take you through topics such as Heat Flow, Moisture Flow, Air Flow, Indoor Air Quality, Evaluating HVAC or Mechanical Systems in the Building Envelop and Sound Control Problems.

Be forewarned, each webinar is a half hour longer than the last.  It is like a three course meal that will leave you both full and wanting more.

The first session will be held on Wednesday, March 12 from 5:30 – 6:30 pm EST.  If you are looking to expand your knowledge of Building Science, this accredited course is for you!

The Transparency Movement Sets a New Standard

Think about it, metrics for sustainability provide fact based defenses for faith based decisions. A Life Cycle Assessment (LCA) on an individual product is an example of a fact based defense for choosing a specific material.

For example, say that you set a criterion of global warming potential as your decision making criteri0n. How could you compare vastly different types of material to learn which has a greater impact? Now you can because the LCA provides that level of information. 

Now, if you look at sustainable buildings as opposed to sustainable materials the LCA is the natural way of taking the information and expanding it to the building level. Setting the correct discrete limits up front creates a potential for the limitless. We can take this same measurable – global warming potential – and expand it across the whole building assembly.  Can we say that this building is more sustainable than another?  Absolutely we can – the metrics are in place. Simply pick what is important to you.  After all, sustainability means different things to different people.

There are a whole range of important metrics that people can use in their consideration process. All the information is available and there are systems in place to be able to expand across the building such as the LCA.

So it is now possible to defend your faith in sustainability with facts; as long as you understand the systems like LCA and the information that is available.  Maybe faith is making a comeback.
