Off-Grid Community Buildings: Energy, Water, and Material Strategies

Urban nature centers bring environmental education into dense cities, and their buildings teach as much as their exhibits do. A center that treats its own wastewater, generates its own electricity, and runs on a fraction of the water a conventional facility uses makes the case for sustainable design in measurable numbers. The first building in […]

How LEED Evaluates Wood and Biobased Building Materials

Wood occupies a particular position in green building. It is renewable, stores carbon, and comes from a biological process that most rating systems want to reward, yet certification rules have never fully agreed on how to verify that the wood in a building actually came from a well-managed forest. That disagreement has shaped wood construction

How to Choose Sustainable Building Materials for a Healthier Home

Choosing what to build with used to be a simple exercise in price and availability. Contractors picked from a short list of familiar products, and owners rarely asked where the materials came from or what was inside them. That has changed. The design and construction community has been demanding more information transparency on products, and

Green Building Research Tools: Archives, Product Data, and Energy Strategies

Green building knowledge compounds. Firms that deliver efficient, healthy, low-carbon projects keep a running library of what works: product data, energy strategies, code changes, and lessons from completed jobs. Building that library takes time, and the payoff shows up in every estimate and specification. It also depends on the people doing the work, since a

Make It Easy for Homeowners to Be Green: A Green Building Priority

Green building is usually measured in certifications, insulation values, and airtightness numbers, but the people who live in the house decide whether any of it works. A high-performance home that is difficult to operate will perform worse than a modest home that is easy to run. That is why the number ten priority in the

Blower Door Testing for Commercial Buildings: How Airtightness Testing Works

A nearly complete grocery store building in Vermont was pressure-tested in the final weeks of construction, and the results told the design team exactly how well the envelope had been built. The practice is routine in a few corners of the industry and almost unheard of elsewhere. Most commercial buildings and houses are handed over

Renovate or Tear Down: How Builders Decide What Happens to an Older House

Across the country, older houses are being demolished and replaced with dramatically larger structures that crowd the lot line. The pattern shows up in nearly every metro area with a hot housing market: a sound house comes down, a bigger one goes up, and the block changes character overnight. Trees disappear, backyards shrink, and neighbors

Sustainable Sealants: The Challenges of Predicting Service Life

Caulk joint sealants are a small line item in a construction budget, yet they decide how long a building envelope stays watertight. When a bead fails, water finds the air barrier, insulation loses its rated performance, and occupants deal with drafts, dampness, and degraded indoor air. No one can say with certainty when a given

How Design Leaders Get the Most From Greenbuild

Greenbuild, the world’s largest conference and expo built around sustainable design, overwhelms first-time attendees with scale. Exhibitors crowd the expo floor, education sessions run in parallel all day, and the schedule fills from breakfast to late evening. Design leaders who return year after year manage the event differently: they lean on peer networks, use short-format
