What It Will Take To Transform Buildings in Large Cities

— January 22, 2015

From New York to Los Angeles, a growing number of the largest U.S. cities are recognizing that tackling building efficiency translates into progress toward climate resilience.  The underlying assumption is that better information leads to action.  As these cities compile baselines on commercial building energy use and educate the public on the cost-effective opportunities for energy reductions, the next question that arises is whether building owners will take action.

New York State of Mind

New York City was the first to launch a comprehensive strategy to tackle energy waste in commercial buildings through four local laws under the Greener, Greater Buildings Plan.  The complementary laws not only mandate energy benchmarking but require performance upgrades to meet local energy codes for citywide renovations, major retrofits in buildings over 50,000 SF to meet lighting efficiency standards, and the installation of submeters by 2025.  Mayor Bill de Blasio has continued the commitment to improving the city’s climate readiness and, in September, announced a new goal for a citywide 80% reduction in greenhouse gas emissions by 2050.   According to a recent article in The New York Times, the mayor’s office estimates that the energy efficiency advances in buildings deliver tremendous economic benefits.  According to the director of the Mayor’s Office of Recovery and Resiliency, the city spends $800 million a year to run its facilities, and energy efficiency retrofits could generate $180 million in annual savings by 2025.

Best Practices

The City Energy Project (CEP), a national initiative directed by the Institute for Market Transformation (IMT) and the Natural Resources Defense Council (NRDC), aims to help 10 cities design energy efficiency plans and share best practices for promoting change in their largest commercial buildings.   Atlanta, Boston, Chicago, Denver, Houston, Kansas City (Missouri), Los Angeles, Orlando, Philadelphia, and Salt Lake City have each joined the project, according to the CEP fact sheet. As outlined on the CEP website, in 3 to 5 years, the initiative will create transparency on building energy use and create financial vehicles for investment in energy efficiency.

New financing channels are a critical element in the mission to tackle commercial building energy efficiency.  While many of the most attainable energy efficiency improvements can be low-cost or no-cost improvements through scheduling and procedures, transformational changes require capital investment.  The challenge is how to engage building owners with financing mechanisms that enable those investments.

Opening the Purse

At the 2014 World Energy Engineering Conference, held in October in Washington, D.C., several sessions honed in on the challenge of financing energy efficiency.  The market recognizes the opportunity and benefits associated with energy efficiency, but the reality is that capital budgets are tight.  Former President Bill Clinton, the keynote speaker, declared, “Financing is holding back the energy revolution.”

In Navigant Research’s view, the challenge is two-fold.  On one hand, there is the opportunity to adjust perspectives on energy efficiency investment.  Advocacy efforts, such as the CEP, could help building owners broaden their views from a focus on payback to a longer-term view of how energy efficiency and intelligent building investments enhance the value of their facilities.  On the other hand, our research suggests that a change is underway in the performance contracting and shared savings models that have helped fuel investment in energy efficiency historically.   Watch for a new report on energy service companies and the transformation of intelligent buildings financing in 2015 as a part of our Building Innovations Service.

 

Explosive Growth Drives India’s Smart Cities Movement

— January 19, 2015

In June, Prime Minister of India Narendra Modi announced the country’s goal for the development of 100 smart cities.  Fundamental to this vision is the development of smart buildings.  According to a recent article by Surabhi Arora, director of research services for Colliers International, “The advantage of following smart building concept is that they can be considered as future-proofed assets. … The shift to smart buildings has only just begun, and will now accelerate very quickly with proactive government support.  It is the time for forward-thinking developers and landlords to prepare themselves to lead, rather than follow, the change.”

My colleagues James McCray and Lauren Callaway recently commented on the drive to create a more resilient and smarter grid in India.  As with that effort, India will face some inevitable challenges on the path toward developing smart buildings.  According to the United Nations, Indian cities will see populations burst with an additional 404 million people by 2050.  This rate of urbanization will put unprecedented pressure on city infrastructure and resources.  Smart city and smart building goals speak to the priorities for sustainability, climate change readiness, and human welfare, but economic commitments will be critical to see these objectives come to fruition.

Outside Forces

The international community has recognized the opportunities in India, and Japan, the United States, and Singapore are major government allies for the Indian smart cities agenda.   According to an article in Forbes, the Delhi Mumbai Industrial Corridor (DMIC), a 1,000 kilometer stretch between Delhi and Mumbai, will be a major focus of the smart cities development plan.  It’s projected that the new manufacturing and commercial centers within the smart cities will require upwards of $90 billion from international investors.  The smart city development in this corridor is integral to the nation’s vision of becoming the “Global Manufacturing and Trading Hub,” according to the DMIC Development Corporation, the government partnership between India and Japan.  The international interest for participation in the development of these smart cities also stems from major technology companies such as Microsoft and IBM.

A Chicago a Year

The Indian government is pushing the smart city agenda forward through an important round of stakeholder planning meetings that began at the end of December.  The government recognizes that accomplishing its vision will be no small feat; as one government official explained, “a new Chicago needs to be built every year.”  The political commitment, international interest, and growth demands in India represent a major opportunity for smart building technology companies.  India’s smart cities movement could demonstrate how smart buildings deliver significant cost savings through energy efficiency and strategic facilities management, and could become a hub for the spokes of the smart city infrastructure.

 

Back to the Land, in the City

— December 23, 2014

Urban farming may sound like an oxymoron, but more and more cities are looking at the role of urban food production to reduce the embedded carbon cost of transporting food long distances (food-miles), to improve food education, and to regenerate run-down city areas.

In many cities, of course, there has never been a clear line between the city and country.  A new study, for example, indicates the degree to which urban farming has a significant role in city economies.  According to the report from the International Water Management Institute (IWWI), around 69 million hectares (around 6% of the world’s cropland) are being cultivated within cities.  Furthermore, 456 million hectares (1.1 billion acres), an area roughly the size of the European Union, is under cultivation in close proximity to urban environments.

Urban farming is widely practiced across the world: 87% of cities greater than 50,000 have some irrigated farming and 98% having some rain-fed cropland.  The report suggests that there is significant potential for the local sourcing of food for the growing cities of the developing world, but it also highlights the issues this presents in terms of water and wastewater management.  In particular, a lack of water treatment facilities means that there are significant dangers to human health from cultivation that uses unclean water.

Scaling Up

In Accra, for example, 10% of the city’s wastewater may be used for urban farms without adequate treatment.  Another study has estimated that 85% of cities discharge their wastewater without appropriate treatment.  Strategies to support and expand local food provision for growing cities must, therefore, be closely aligned with improvements to water distribution and water treatment systems. Developing cities need to find ways to integrate existing urban farming sites with their water management and land use policies if they are to retain the benefits of local production.

In the developed cities of North America and other parts of the world, urban farming has been recognized since the 1970s as an important tool to help community regeneration programs in areas like the Bronx in New York.  Now cities are looking to technology to make local production viable at a commercial scale.

To Feed the Center

For example, Lufa Farms is running two rooftop gardens in Montreal using hydroponic technology, which provides nutrients to plants through an integrated water system rather than soil.  They have also been reassessing the sales and distribution issues that are equally important to make urban farming commercially successful.  Other technologies to enable large-scale urban food production include aquaponics, which integrates fish and plant farming, as practiced by Urban Organics in St. Paul, Minnesota. Urban Organics is located in a former brewery and is part of a broader, city-supported urban regeneration program.  In Europe, LokDepot in Basel, Switzerland is the first commercial aquaponics farm.

Any true measure of a city’s total energy consumption, its environmental footprint, or its economic resilience needs to consider the relationship between the urban center and the resources on which it relies.  Food production is one of the most important of those resources.   In different ways the community gardens and high-tech vertical farms of North American and European cities and the farming enclaves of Accra and other cities in Africa and Asia all show how cities need to think more locally about food production.  As droughts and expanding urban populations put pressure on water supplies and food costs, an intelligent approach to food production will become a critical issue for many communities.

 

Street Lights Add EV Charging

— December 11, 2014

Sometimes a solution forms at the intersection of two challenges that may not seem, at first glance, to have anything in common.  For example, cities are perpetually seeking ways to increase revenue, and many owners of electric vehicles (EVs) want access to ubiquitous charging infrastructure.

Enter the new concept of retrofitting street lights with money-saving LEDs and EV charging ports.  City managers are moving toward central control of street lights by adding a control node, which enables them to reduce cost and integrate the lights with other systems, as my colleague Jesse Foote recently wrote.  With smart street lighting technology (as covered in Navigant Research’s report, Smart Street Lighting) in place, EV charging capabilities can also be added to street lights, creating a new revenue stream for municipalities.

A Light and a Charge

Among the first pilots of this combination are occurring in the cities of Munich in Germany, Aix-en-Provence in France, and Brasov in Romania.  BMW has two such lights at its headquarters in Munich and will add a series of enhanced lights in the city next year.  A consortium called Telewatt, led by lighting manufacturer Citelum, is similarly installing LED street lights with EV charging in Aix-en-Provence.  In Romania, local company Flashnet has integrated its inteliLIGHT management platform with an EV charger.

Motorists can pay for the EV charging using a mobile phone app.  Cities that have regulations allowing them to provide EV charging services can gain revenue to help balance the books.  They can also balance the additional power demand of EVs within their overall power management system.  Placing a Level 1 or Level 2 charging outlet on a light pole reduces the installation cost of bringing power to the curb, which otherwise can be several times greater than the cost of the equipment.  Cities that install these systems will help drive demand for EVs, which has the added benefit of increasing urban air quality.

This is another example of the integration of seemingly disparate city services into a smart city.  As detailed by Navigant Research’s Smart Cities Research Service, the move toward integrating power, water, transportation, waste, and building management will yield considerable savings while improving the quality of urban life for city dwellers.
