Skyscraper Sunday: 1800 Larimer LEED Silver Office Tower (Denver)

1800_larimer 1800_larimer_night

Apparently, the mid-1980s was the last time a new high rise office building was built in Denver, Colorado.  We know what happened then and why skyscraper construction halted (hint: construction loans/S+L Crisis); knock on wood…S+L 2.0??  Recently, Westfield Development announced plans to build the most energy efficient high rise in downtown Denver, 1800 Larimer–actually, it’s a $150 million, 22 story, 500,000 square foot, energy-efficient, proposed LEED Silver tower.  Westfield Development President Rich McClintock said, "if it is not a sustainable building, it is outdated."  I couldn’t agree more. 

This LoDo area building was designed by Denver-based RNL Design.  Some of the features include the following:  subfloor air distribution system; 9-foot, 6-inch floor-to-ceiling windows; state-of-the-art health club for tenants; a half-acre terrace parklike environment 20 feet off the ground; tenant controlled temperature system; blue + gray glass facade; trees in the lobby; and a 30-foot high "wall of water" inside the lobby.  I’m excited that new construction is going green, but I will say that Denver is working hard to make the right choices.  This green building is, after all, only a small kog in the greater machine initiated by Denver’s Mayor Hickenlooper called Greenprint Denver

I keep saying this, but the smartest cities are also the greenest:  San Francisco, Portland, Denver, Austin, Chicago, and a trailing Salt Lake City.  The human capital + brain power of these cities is really mind-boggling, so where are you going to live?  Via RMN

UPDATE:  According to the global votes of over 100,000 people, Mayor Hickenlooper was ranked #9 in a survey of best mayors in the world that have made long-lasting contributions to their cities.  Only one other US mayor made the list.

GreenCity Lofts: A Modern Step in the Green Direction

Front

First off, GreenCity Lofts LLC shows us how important it is to have a sleek, professional, informative website for your properties.  In the early stages of construction, word-of-mouth increases and people start to notice what’s going on.  Slap a huge sign up (with a rendering of course) and direct people to the web for more information while the building is still being finished.  A good website that’s search engine optimized (SEO) will go a long way to promoting a new building’s features and benefits.  I’ve gleaned my information from GreenCity’s website and an article in the December/January 2007 edition of Dwell Magazine.  Designed by Architect Robert Swatt, this eco-conscious complex has 62 units in 5 buildings, with units ranging in size from 500-2100 square feet, and prices from $495,000-$1,050,000 (800 – 2100 square feet). 

Green Features:
The building exceeds California Title 24 energy requirements by 15% and is Energy Star qualified; 95% of the demolition waste from construction was recycled; the steel superstructure + interior framing contain from 25-90% post-consumer recycled content creating a durable earthquake, fire, rot, mold, pest-resistant building; cement pours contain a minimum of 25% fly ash; the roof was painted gray to absorb less heat than the darker colored varieties; water efficient technologies collect rain water runoff for landscape irrigation; hydronic radiant floor heating with a gas-fired broiler saves 20-40% of the cost of conventional systems (and you have no noise or draft as in the forced-air systems); formaldehyde-free products were used where possible; zero + low-VOC paints, stains, and varnishes were used; units contain bamboo floors with other FSC-certified wood products; and lofts contain 2-3 walls with windows for abundant natural lighting. 

These places look really good, too.  One thing to consider, is the trade off when you create places with large, open, interior spaces.  It takes more energy to heat and cool larger spaces, but this may be mitigated some by using the hydronic radiant floor heating.  At least you don’t have to walk on the cold bathroom tiles when you wake up in the morning!  Oh yeah, also, GreenCity Lofts is about a 13-minute walk from BART, on the border of Emeryville and Oakland at 1007 41st Street, at the corner of 41st Street and Adeline.  Watch the GreenCity Lofts’ video

Madison Wisconsin's Capitol West Development Goes Modern + Reuses/Deconstructs +94%

309_west_washington Main_street_townhomes

It seems like cities all over the United States are jumping into the green building fray–it’s an exciting time to witness the radical transformation of the construction industry.  In Madison, Wisconsin, there’s a neighborhood development called Capitol West.  The project is a $110 million, mixed-use development in the center of Madison, occupying an entire city block bounded by West Washington Avenue, South Henry, West Main + South Broom Street.  The development will include a diversity of housing types, shopping spaces, + urban parks–all clean, contemporary + modern. 

Boom_street_lofts This urban redevelopment will include about 375-400 townhomes, condominiums, and lofts + penthouses.  The first phase (173 condos + 10,000 sf of retail) of condominium homes will range in size from 650-3,000 square feet, with prices ranging from $170,000-$900,000.  I was really surprised by the diversity of architecture and offerings for this neighborhood:  Capitol Court Townhomes, Washington Rowhouses, 309 West Washington (10 floors), Main Street Townhomes, + Broom Street Lofts.  This looks really exciting. 

What’s really impressive is the steps the developer, The Alexander Company, took to make sure this development didn’t place undue burden on the city’s resources.  It retained Madison Environmental Group to head up their reuse/deconstruction phase.  The reuse phase diverted 66 tons of material from the landfill via donations, walk-throughs, and public sale events.  The deconstruction phase yielded 94.86% of recycled material, totaling 24,500 tons!  Granted deconstruction can take more time, but it’s a lot better on the community, environment, and neighborhood.  In total, 59,536 cubic yards of material was diverted from the landfill via reuse and deconstruction efforts–that’s 19,772 Ford F-150s full of waste lined up back-to-back stretching 65 miles.  Nice job Capitol West.

No word yet as to whether any of the individual projects will go after LEED, but the architects are designing with the environment in mind.  Lots of natural light, air + ventilation design with incredible views, green spaces, and roof gardens.  Thanks for the tip Stephen Schenkenberg
