Energy Efficiency

A Denver initiative on the November ballot seeks to sprout more trees, shrubs and even vegetable gardens atop larger buildings across the city, a move that would accelerate a trend that has been embraced by some developers.

Oregon’s goal, as laid out in the executive order signed last week, is to achieve net-zero energy-ready buildings as standard practice across the state.

Built Green is excited to share its recent study, the largest of its kind. The study compared actual electricity use in homes certified by Built Green and non-certified homes. The results revealed that in some cases, Built Green homes were twice as efficient as predicted!

Developers of single- and multifamily homes these days strive to make them as high performing as possible.

Doing so comes with considerable benefits for both builders and buyers:

  • Lower energy expenses
  • Healthier indoor conditions
  • Less maintenance
  • Higher resale values

Windows and doors play key roles in a structure’s performance as the largest openings in thermal envelope and are responsible for the bulk of conditioned air loss in a home.

Today, during the Communities and Affordable Housing Unit at the annual Greenbuild Conference and Expo, GBCI announced its adoption of the RELi standard.

Starting in 2020, with the next cycle of energy codes enacted by the California Energy Commission, the bar will be moved up to the highest it's ever been for newly built homes.

KB Home, the first RESNET Energy Smart Builder, is joining RESNET to mark important milestones for the energy-efficient homebuilding. KB Home recently delivered its 25,000th home in Denver and RESNET reached more than two million HERS Index-rated homes nationwide.

A new rigid foam insulation considered a fit for any vertical construction application where a high-performance building envelop is desired has been unveiled.

Despite  being the perfect application of cladding, weather-resistant barrier (WRB), foam sheathing, air barriers, studs and so forth, the perfect wall is not necessarily the most practical or preferred solution for every building project.

A report by Transparency Market Research (TMR) forecasts the global rigid polyurethane foam market to clock a CAGR of 6.0% between 2017 and 2025. Progressing at this rate, the market’s valuation of US$15.2 bn in 2016 will become US$25.5 bn by the end of 2025.
