Mandatory Energy Benchmarking.. Coming to a City Near You?

Measurement enables Management; Transparency enables Accountability… The quintessential concepts driving adaptation of mandatory energy benchmarking legislation.

Commercial_Benchmarking_Policy_Matrix (cities) - 8.1.14 (2)

Mandatory energy benchmarking represents a pivotal step towards reforming energy usage in American cities, as it galvanizes populations through collective reduction. Like any immature “innovation”, the practice faces barriers and static hindering widespread adaptation and dissemination into the mainstream.

What factors influence proliferation?

Unique building stock and varied regulatory needs necessitate city-specific reporting plans. Until there is a scaleable model of best-practices, development will continue to be resource and time intensive for administration.

Complexity in execution threatens data integrity and program usefulness. Unintentional errors, difficulty in obtaining information, and unfamiliarity with ENERGY STAR’s Portfolio Manager all weaken database strength. The remedy lies in educating elected reporters. Program handlers must be well versed with the operations and techniques necessary to perform their role effectively.

Stakeholder push-back during implementation deters participation and damages program reputation. Greater visibility of post-retrofit results will dispel doubts of program usefulness, while increased availability of financial incentives will quiet claims of marginalization [under-performers stigmatized as poor living options] and unfair penalization [fining of historic buildings or financially underserved properties].

Notes from Abroad: A SWArrior in Sweden

In October, NESEA awarded SWA’s Heather Nolen with a travel scholarship through the Kate Goldstein Fund for Emerging Professionals (you can read the announcement here). Heather joined four other scholarship recipients for a two week  journey to Denmark and Sweden to explore  innovative sustainability methods being used in their buildings. The following is blog entry written by Heather, describing her experience at a location outside of Stockholm. (This entry was reblogged from NESEA’s blog; you can find the original post here.)

We met with Björn Cederquist who was kind enough to tell us about Hammarby Sjöstad, a new sustainable district, which he is quite proud of.

Stockholm is a growing city, with a population of 1.5 million and a serious lack of housing. The city central is quite developed, outside the city there are the typical suburbs, it is the area between the city proper and the suburbs that Stockholm is looking to develop in a planned, sustainable manner. To meet the city’s housing needs Stockholm plans to construct 8,000 units per year, mind you they have only been building at 5,000 units/year of maximum. This is a large undertaking for the city which is being planned in a thoughtful way.

Despite the need for more units of housing there is a strong tradition in Stockholm of midrise buildings which accounts for the reluctance to build higher. Hammarby Sjöstad is mostly mid-rise with one exception, a single 12 story building.

Located in this prime area between the city and suburbs, Hammarby Sjöstad is located at an old harbor and landfill turned Brownfield site. To convert this piece of land into a residential community public transportation had to be extended, both the subway and train lines. The presence of transit shows a commitment to the area, a feeling of permanence which is required to build the community. 80% of residents commute by public transit.

To meet sustainability goals in a comprehensive way the district aimed to be a healthy place for people to live that stimulates the body and soul with opportunities for exercise, sports and culture. Design began in 1990 to construct an “Environmental and Ecological City District,” which includes 11,000 units housing over 25,000 people; an additional 10,000 are projected to work within this area. In addition to the housing and transit systems, power plants were constructed to provide district heating and cooling, waste removal including organic waste, public water supply and wastewater treatment.

Renewable energy sources, harvesting of energy from the areas wastewater system, burning of waste combustibles along with harvesting energy from the sewage system allow Hammarby Sjöstad to operate their CHP plant free of fossil fuels. Central heat pumps at the district plant operate year round to extract energy which allows for district cooling, planned for 10 years the plant is the largest in the world. The wastewater treatment plant harvests both bio-gas and bio-solids. Bio-gas is used to power buses, taxis and some individual stoves. Bio-solids are used as fertilizer in forest, filling mines and soon to be used for agriculture purposed. Combined with advanced waste collection and energy efficient construction Hammarby Sjöstad is a unique community which is a product of long-term planning and collaboration. Sites underdevelopment are learning from Ham Hammarby Sjöstad to further advance eco-districts for long-term success.
