Building enveloped that perform poorly reduce energy efficiency, increase ROI times, and increase carbon footprints and utility bills for building owners. A blower door test can help to establish the airtightness of small to medium buildings, measure the flow of air between different areas in a building and test the airtightness of ductwork.
Radiant barriers are utilized to reduce summer heat gain in attics and help to improve the efficiency of green building envelopes. A radiant barrier can lower heat transfer from attics to the building below, keep the attic space cooler and lower cooling costs by up to 17% in warmer climates. We take a look at how radiant barriers work, the different types of radiant barriers and some of the misconceptions surrounding them.
Knowing your climate zone and building accordingly is one of the basic tenants of building science. Moisture, extreme temperatures and inclement weather require completely different building techniques to ensure longevity and efficiency. When you know your building climate zone you can select techniques and materials that are safe, cost effective, and efficient to install and provide an energy efficient building envelope.
One way to work smarter is to build using raised-heel trusses. From the APA: “Also known as energy-heel trusses, raised-heel trusses deliver cost-effective energy performance especially when combined with continuous plywood or OSB sheathing.”
If you have been administering your blower door test at the end of your build, then you may be missing out on an essential opportunity to make your building envelope even tighter. Doing two blower-door tests; one mid-way through your build and one at the end, will give you a unique opportunity to fix cracks and holes before they get covered over by insulation and sheetrock.
Condensation is moisture that can lead to a myriad of problems from water damage to mold. With the tighter building envelopes of modern structures, this condensation problem is exacerbated as reduced air flow can prevent moist areas from drying out. Luckily there are ways in which you can mitigate the conditions that lead to condensation and keep moisture out of your home.
The dreaded call-back from an unhappy customer often takes up time and money that eats into your profit margins. However, successfully dealing with these issues can boost your customer service and improve word-of-mouth business. Turn your clients into raving fans with these call-back fixes.
A common summer problem is condensation on walls around AC air vents. Moisture is insidious and, once allowed to enter wall structures, can result in damage, mold and mildew. While quick-fix solutions may provide cosmetic relief, it is best to spend the time and money to ensure that moisture is not seeping into your wall structures.
As construction costs increase and building codes demand more effective building envelopes, construction professionals are looking to taller wall panels to fill in the gaps. OSB wall panels already make for a sustainable and cost-effective option but with longer length OSB wall panels, the efficacy of the building envelope is increased by creating fewer seams while costs, waste and installation time are reduced.
