Kieran Timberlake and PE International have developed Tally, a new analysis tool to help BIM users keep better score of their projects’ complete environmental footprints. When used alongside other critical studies like daylighting simulation and energy modeling, BIM tools like Tally can help construction professionals move towards data-driven analysis for whole building life cycle assessment, writes TriplePundit.com.
Kieran Timberlake explains Tally:
Quantifying environmental impact typically involves performing a Life Cycle Assessment, which is a relatively new and confounding practice for most architects. Currently, no efficient means exists to evaluate environmental impact of materials during the design and planning process, when it can have the most influence on design decisions and building performance. An architect needs this impact data at the time of material specification, but the laborious process required for calculating embodied environmental impact across a broad range of design decisions prevents this from happening at crucial moments in the design process.
In principle, Building Information Modeling (BIM) ought to enable architects to acquire this information, but in practice, projects are not modeled to a sufficient level of detail to account for all of the materials in a building at their actual volume. In order to address these challenges, we invented Tally™, a Revit app that allows users to imbue each assembly with information about the architectural products it contains. Tally™ quantifies embodied energy along with other environmental impacts and emissions to land, air, and water. It can be used for whole-building analysis or for comparative analyses of various design options, and it can account for the diverse range of material classes defined in a BIM model, as well as materials that are not modeled explicitly.

How Building Teams Choose Roofing Systems
A roofing survey emailed to a representative sample of BD+C’s subscriber list revealed such key findings as: Respondents named metal (56%) and EPDM (50%) as the roofing systems they (or their firms) employed most in projects. Also, new construction and retrofits were fairly evenly split among respondents’ roofing-related projects over the last couple of years.

Mixed-Use on Steroids
Mixed-use development has been one of the few bright spots in real estate in the last few years. Successful mixed-use projects are almost always located in dense urban or suburban areas, usually close to public transportation. It’s a sign of the times that the residential component tends to be rental rather than for-sale.

Product of the Week: Zinc cladding helps border crossing blend in with surroundings
Zinc panels provide natural-looking, durable cladding for an administrative building and toll canopies at the newly expanded Queenstown Plaza U.S.-Canada border crossing at the Niagara Gorge. Toronto’s Moriyama & Teshima Architects chose the zinc alloy panels for their ability to blend with the structures’ scenic surroundings, as well as for their low maintenance and sustainable qualities. The structures incorporate 14,000 sf of Rheinzink’s branded Angled Standing Seam and Reveal Panels in graphite gray.

LEED standards under fire in NYC
This year, for the first time, owners of 25,000 commercial properties in New York must report their buildings’ energy use to the city. However, LEED doesn’t measure energy use and costs, something a growing number of engineers, architects, and landlords insist must be done. Their concerns and a general blossoming of environmental awareness have spawned a host of rating systems that could test LEED’s dominance.

California buildings: now even more efficient
New buildings in California must now be more sustainable under the state’s Green Building Standards Code, which took effect with the new year. CALGreen, the first statewide green building code in the country, requires new buildings to be more energy efficient, use less water, and emit fewer pollutants, among many other requirements. And they have the potential to affect LEED ratings.
