OVERVIEW

The building enclosure manages everything that might get into and out of a building: water, wind, light, sound, air, pests, and people. Assemblies are the foundations, above-grade walls, and roofs that make up the enclosure, and how they’re put together makes all the difference to how well the building performs—and for how long.

Here you’ll learn the importance of continuity at assembly transitions, and how to help ensure that the whole team—from architect to structural and mechanical engineers to construction managers and subcontractors—is educated about moisture risks and is accountable for quality work.

  • Choosing Between an ERV and an HRV

    Primer

    Don't get fooled into buying a more expensive and complex system if what you really need is a dehumidifier.

  • Introduction to High-Performance Building Assemblies

    Webcast

    In a one-hour on-demand webcast, acclaimed teacher and consultant Peter Yost will give you the building science knowledge and practical guidance to start getting higher performance from your building assemblies.

  • How Active Dehumidification Works

    Primer

    Whether you choose a refrigerant-based or a desiccant-based system, dehumidifiers use energy and produce waste heat.

  • How "Smart" Vapor Retarders Work

    Primer

    Vapor retarders are supposed to keep our buildings dry, but they sometimes keep them wet instead. Enter the "smart" vapor retarder.

  • Basics of the Psychrometric Chart

    Primer

    In high-performance buildings, we have to manage energy and moisture with equal intensity. The psychrometric chart shows us how.

  • Dry-Bulb? Wet-Bulb? What's the Difference?

    Primer

    Dry-bulb and wet-bulb thermometers measure two different types of heat. Understanding them is crucial to understanding building science.

  • What Is Building Science, Anyway?

    Primer

    Building science is an integrated discipline that stands many conventional design and construction ideas on their heads.

  • How Rainscreens Work

    Primer

    Rainscreens don't just keep the rain out: they also encourage drying in case water does manage to get in.

  • How Water Moves Through Buildings

    Primer

    Whenever we improve energy efficiency, we have to deal with water in new ways to prevent damage and mold.

  • Using Fly Ash in Concrete

    Primer

    Fly ash lowers the environmental footprint of concrete and improves durability. Pouring and curing concrete with high levels of fly ash requires special treatment.
