Lifetime Cost Case Analysis: Energy-Efficient, LED-based Commercial Signage

Lightmark_led_1 If you haven’t noticed, commercial enterprises use lots of neon in their signage.  I drove around the neighborhood and found a few gas stations and a Sonic Drive-in with neons wrapped around the structure.  You can tell because the neon lighting breaks at the nodes.  Well, LEDs, while still a nascent lighting technology, have the potential to become the future signage lighting behemoth, if building owners can catch on to their benefits.  To get to that point, however, the stars will need to align so that the key decision maker does a costing analysis incorporating the operational benefits, in addition to the sticker price (initial costs). 

LED Technology Benefits:
LEDs have energy savings of up to 80% over neon lighting.  In addition to the energy savings, LEDs differ in size and electronic control.  Point blank, with LEDs, there’s reduced maintenance, reduced energy consumption, better light quality output, safer + lower voltage requirements, and low temperature performance.  They last longer, too.  There’s no gap in the illumination like there is with the neon.  And with a technology like LightMark, the units are variable so you use just the right amount for the project.

Costing + Payback:
LEDs pay for themselves in about 2-3 years.  When a decision maker is comparing neons (or some other light source) and LEDs, it’s important to make sure that the comparison is apples-to-apples.  Use a "lifetime cost of ownership" analysis:  (1) initial purchase price + (2) initial installation costs + (3) lifetime energy usage + (4) lifetime maintenance charges.  I’d suggest two more external considerations, which aren’t factored into the lifetime cost of ownership.  First, consider the extent of liability (i.e., if neons tend to flame up at gas stations more than LEDs, there’s a tangible savings benefit [note - this may or may not be true]).  Second, consider the tax implications (i.e., state, local, or federal government offers tax credits/deductions for LED use, etc.). 

A few companies that have been incorporating this new technology include Arco, A&W, BP, McDonald’s, KalTire (Canada), Tsutaya (Japan), and Petro-Canada.  What it takes, however, is a paradigm shift from initial cost, or sticker price, to lifetime cost, and if owners aren’t making the change, the contractor should speak up and create value for the customer.

Jennifer Siegal, Office of Mobile Design, the Modern + Green Take Home

Take_homeQuoting Jennifer Siegal, founder of Venica, California-based Office of Mobile Design (OMD):  "I’m interested in how technology is influencing the way we form communities…because our lifestyles are demanding more lightness, our buildings shouldn’t be sitting so heavy."  Siegal was featured in the October 2006 issue of Fast Company magazine, and praised as a "fresh face from the front lines of design."  In a world where renderings are common and completed projects are not, aka, the prefab world, Siegal is really staking a claim in this ultra-stylish, sustainable chase for comfortable, affordable living.

Siegal’s work includes the Mobile Eco Lab (1998), Portable House (2001), Seatrain House (2003), and the Swellhouse.  Her most recent work is a modern, modular home product line called Take Home.  Go to the website and take a gander at her captivating architecture.  You’ll find also that her work goes beyond the realm of aesthetics and mid-century modern vernacular and into sustainability.  That’s going to be where architects will make a huge difference, I believe.  In addition to that, I think OMD is taking pro-active steps to clarify the pricing of their prefabs and make modern + sustainable living more affordable.

Sustainability:
Sustainability is a key issue in the design process at OMD.  Prefab presents the natural green benefit of avoiding all the construction waste that plagues stick-built construction.  With the Take Home, OMD also offers precision steel construction, high-end amenities (Italian Boffi kitchens + Duravit bathrooms), fully landscaped courtyards with pools, passive cooling systems, and AVAILABLE 100% solar power and water heating.  Also available is bamboo and radiant heated flooring.  Homes range in size from 800-5,000 square feet and cost $210-270 per square foot.  Not bad at all!

Skyscraper Sunday: LEED Platinum Genzyme Center

Anton_grassl_genzyme_rendering This building is a little old hat for many of the readers here (it was an AIA/COTE Top Ten Green Project in 2004), but I think there are some important aspects of the projects that can be remembered and applied to new green projects.  This building is in the highest eschelon of LEED ratings, the platinum standard (LEED-NC, v2), and if you follow the links below, they’ve been generous enough to explain how they received all the points towards Platinum certification.  You can even take a virtual tour of the building if you’re interested. 

The building is the corporate headquarters for a biotechnology firm and houses 900 employees in 12 floors.  Here are some of the many green features:  high performance curtainwall glazing system with operable windows on all 12 floors; steam from local plant is used for heating + cooling; about 1/3 of the building uses ventilated double-facade that blocks summer solar and captures winter solar gains; the central atrium acts as a huge return air duct and light shaft; air moves up the atrium and out exhaust fans near the skylight; natural light is brought in from solar-tracking mirrors above the skylight and reflected deep throughout the building; the building saves water use comparably by 32% by using waterless urinals, dual flush toilets, automatic faucets, and low-flush fixtures; storm water supplements the cooling towers and irrigates the landscaped roof; partial electricity generation is provided by the building integrated photovoltaics (PV); nearly 90% of the wood is FSC-certified; and the building materials were chosen based on low emissions, recycled content, and/or local manufacturing.  Not a bad list!

Really, I think this enormous achievement required the collective efforts of many different players with a similar vision.  Architect and lead designer was Behnisch, Behnisch & Partner, executive architect – base building was House & Robertson Architects, tenant improvements architect was Next Phase Studios, landscape architect was Michael Van Valkenburgh Architects, and Turner Construction Company was the contractor.

Current Energy: The World's First Home Efficiency Store

Current_energy_map This is not an advertisement or a commercial.  I was going to the iPod store on Knox (in Uptown, Dallas) and noticed this new store right next door called "Current Energy."  Tag line:  "We’ll plug you in."  I liked the design of the store and decided to go in and check the place out.  First impression, these people are very friendly and eager to help.  Second impression, what are they selling?  That’s below.  The store was pretty cool, and the website‘s not too shabby either. 

Here’s what they are selling/explaining/consulting, etc.:  Rinnai tankless water heater, Rainbird irrigation control, Toto dual flush toilet, Honeywell digital thermostats + air treatment systems, Lutron + Crestron whole house controls, Mitsubishi Mr. Slim ductless air conditioner, Neptune cfl + lighting science group LED lights, Trane xl19i Seer air conditioner, Radiant Barrier products, Vista window tinting and solar screens, Owens corning insulation products, etc.  They have a consultation room, kids learning center (using state-of-the-art macs and computer games), and home energy resource library. 

They give you information on switching your electric provider (explaining both the low-cost options (Gexa) and green options (Green Mountain)).  They can talk you through the benefits of Energy Star and you can ask them all sorts of questions.  They provide energy audit services, etc.  I did stump them a couple times with my questions, but they were willing to get the answers.  If you’re thinking about renovating, buying, building new, or whatever, you should educate yourself and go talk to these people.  They’ll open your eyes to new ideas, that’s for sure.

Green Valley Lofts Raise the Bar for Innovative Mixed Use, Sustainable Development

Building_rendering_1 There really, actually, truly, factually, legitimately is a growing interest in living in more environmentally sensitive buildings.  Even still, whether you’re looking for a single family home, urban townhome, downtown loft, or warehouse loft, the players in the green development field are few and far between (but increasing).  I noticed an interesting developer that is building the "first ‘zero energy’ sustainable mixed-use building in Las Vegas."  This green development, called the Green Valley Lofts, is minutes from the Vegas strip and neighbors all the urban amenities one could ask for (gym, restaurants, banks, dry cleaner, car wash, etc.).  It’s lined to be LEED Certified, too. 

Green Features:
The building will have a stainless steel substructure with floor to ceiling Heat-Mirror insulated glass (benefits include improved interior comfortability, reduced fabric fading, and maximum noise control), aka the EAG Facade.  Also there’s a rooftop solar-photovoltaic system, energy-efficient (non-ozone depleting) closet-type water source HVAC system, low wattage lighting, Energy Star appliances, tankless water heaters, eco-space elevator, whole house central water filtration system, programmable thermostats, zero- to low-VOC non-toxic paints, and bamboo flooring.  The company has a nice description of the benefits of these green features online. 

The interior will include all the amenities that a modernist would desire:  imported Italian kitchens, recycled glass countertops, bamboo flooring, remote controlled window shades, and the whole house lighting system.  Note, some of these features are greener than others.  There’s a glass enclosed roof-top spa as well.

As far as pricing is concerned, these lofts aren’t cheap, but that’s understandable because they aren’t built to be cheap.  Phase 1 prices seem to range from the low $400s to $1.1 million.  And some of the financial incentives that they offer include the popular energy efficient mortgage, the Nevada Power Solar Rebate Program, the usual Federal + State renewable energy tax incentives, and any other energy tax incentives.  What’s better, there will be an raffle and one lucky owner will receive the New 2007 Toyota Camry Hybrid.  Nice business model guys, really.

Texas-OU Weekend: Cup City Installation by Austin Green Art

Cup_city_birds_eye Being Texas-OU weekend, I thought I would bring it back to Austin for a little environmental action.  Back in late September, an environmental organization called Austin Green Art created "Cup City" for the Austin City Limits Music Festival.  The enormous temporary art installation was sponsored by Starbucks.  Cup City should be noticed not for what it is, but what it illustrates. 

The project was designed by architect Legge Lewis Legge and incorporated 41 fence panels (6 x 15 foot), zip ties, and approximately 25,000 pieces of recyclable garbage.  Rent-a-fence provided the fencing.  And from what I understand, the project included solar powered lighting to illuminate the temporary behemoth at night. 

Cup_city_actual Cup_city_profile

The project became a temporary, shaded lounge area where people gathered and interacted during the festival.  But even more importantly, the project illustrates how people need to change the way they consume.  Where talking about massive amounts of water bottles, plastic, paper, coffee cups, etc., that just gets thrown away everyday.  In recycled form, this stuff can be put to use.  Oh, and as a side note, Starbucks donated $1 for every beverage sold at the festival to Austin Green Art, so it’s certain that more of these types of projects are in store for the future.
