Green hollow structure. Fractal generated by Myriam B. Mahiques
We´ve been applying the Green Code this year, and clients are not happy, it makes the construction more expensive but, at least the benefit will be seen in the future. Of course, it´s difficult to explain a benefit that seems to be abstract today.
From builderonline.com these are the green megatrends for this year: (By Claire Easley)
1. Green Building Growth to Rebound
LEED project growth was slow in 2011, only gaining 3% for the year. But while LEED certification on new projects may take longer to gain much steam, the program’s retrofitting arm, LEED for Existing Buildings: Operations & Maintenance (LEED-EBOM), is quickly gaining traction. EBOM project registrations were up 18% last year, and the EBOM project area exceeded the cumulative LEED-NC (New Construction) area for the first time, with 675 million square feet of EBOM versus 649 million square feet of NC. "That trend will continue this year," Yudelson says, as more property owners realize that retrofitting to LEED standards is fairly painless when starting with a building that is already Energy Star–rated.
2. Federal Momentum Has Slowed
The Department of Defense recently stipulated that projects can’t spend any extra money on energy program certification, and while "that’s not necessarily a killer," Yudelson says, "it is an indication that there is some backlash for spending extra money on anything." Getting federal funding for green projects will be harder going forward, he says, especially given the recent Solandra scandal and the federal budget crunch. But while state and local governments aren’t faring much better, that’s where the action will be, he says, as existing buildings will need to be upgraded, projects in the pipeline will move forward, and schools—which are funded by bonds—will need to be built.
3. LEED-EBOM Will Gain Momentum
"We’re going to see this move to other sectors," he says, particularly among hotels with strong convention and meeting businesses who want to be able to market their eco-friendliness. Grocery stores, hospitals, and retail centers are moving in the same direction, with features such as solar panels on top of Walmarts or department stores. "Last month, President Obama and former President Clinton announced the Better Buildings Initiative. It’s only $4 billion, so it’s not huge. But still, this is stuff that moves markets. When you have two presidents pushing something, it does get people’s attention. More and more building owners are realizing that they don’t want to be late to the party."
4. Water Issues Grow in Importance
"Even the water-wet areas have water problems brought on by infrastructure problems and population growth," Yudelson says. "Florida doesn’t have a place for a reservoir in the entire state, so even if you have a slight drought, you have big problems." He predicts rainwater capture systems as well as graywater and blackwater on-site treatment capabilities will become more pervasive. "Instead of toilet to tap, we’re going toilet to toilet."
5. Zero-Net-Energy to Gain Traction
"Zero-net-energy needs to be in your future," Yudelson says, adding that it works best on two- to four-story buildings that only use between 30 and 35 kBTU per square foot per year. "If you do a good job with integrated design, you can reach that [30 to 35 kBTU] goal," he says, adding that getting to net-zero should only add between 3% and 5% to building costs.
6. Green Building Movement Will Continue to Grow
There are currently more than 90 national Green Building Councils throughout the world, and LEED projects have been registered in 161 countries, Yudelson says. Last year, 44% of total LEED registrations were outside the U.S. "This is a movement that you have to pay attention to," he says, adding that the "Big Three" energy rating systems—LEED, BREEAM, and Green Star—are already converging toward common carbon metrics and common rating concerns.
7. Performance Disclosure
Already popular in the European Union and Australia, requirements for buildings to disclose their energy use are gaining traction in the U.S. Beginning April 1 of this year, Seattle will require buildings of more than 10,000 square feet to disclose energy usage, and California will begin requiring disclosures starting next year, which Yudelson says will have a market impact, since prospective tenants will be able to compare what their energy costs will be between buildings. "This is going to happen everywhere, particularly in big cities, because it’s the easiest move to take politically. It doesn’t say you have to retrofit the building. It just says you have to disclose."
8. Global Carbon Ratings
Carbon ratings that remain standard across countries are of particular interest to global property management companies. "If your company is committed to sustainability, you’re going to have to report this," he says. It’s also an issue for property investments tied to pension funds. "Anyone that has sustainable interests and wants access to capital will have to deal with this," he says.
9. Solar Power Stalls
"Solar power is kind of slowing down," mostly due to the costs involved, Yudelson says, adding that focus is shifting instead to energy efficiency. "Solar is still happening. Lots of people like solar … because it’s visible and people want to see something for their money." However, for those building new construction today, he suggests that the most responsible move would be to make it "PV ready," so that as solar becomes more cost effective, it will be cheap and easy to install.
10. Building Management Goes Into the Cloud
As buildings get more complex, Yudelson says, "we’re seeing the need for software that allows us to manage buildings out of the cloud." Thanks to wireless sensors and controls, it’s getting increasingly easier to better direct building managers and maintenance people to locate and fix problems, and to do so remotely.
