Green Buildings - benchmarking, energy efficiency, green building, real estate resources, water efficiency - California Sustainability Alliance

The California Sustainability Alliance is proud to announce an industry report which summarizes the outcome of the Existing Buildings Think Tank Roundtable held in partnership with the USGBC-LA Existing Buildings Committee. Over 70 participants representing building owners and managers, engineers, utilities, government, trade associations, and other industry professionals were in attendance to discuss ideas and emerging trends related to the operation and performance of existing buildings. The Alliance is managed by Navigant Energy Services and funded by Southern California Gas.

The Think Tank Roundtable is an annual, half-day event hosted by the USGBC-LA Existing Buildings Committee and chapter strategic partners typically focusing on Class A buildings. This year, the Alliance sponsored an expanded scope of the meeting to include an afternoon session for Class B and C building owners. The purpose of the Think Tank Roundtable is to share best practices, lessons learned, resources, challenges, and opportunities around topics relevant to owners and managers of Class A, B & C buildings as well as tenants, brokers, government, and building professionals from all sectors. Two industry reports (one for Class A owners and one for Class B and C owners) were produced as a result of the Think Tank event and follow-up interviews with key stakeholders.

Green and energy-efficient buildings demand higher rent, increase tenant productivity, reduce operating costs, and have higher occupancy rates. The upfront cost of green building improvements is a deterrent commonly cited by building owners. However, data show that green retrofits and increased energy and water efficiency increase property values and many upgrades can deliver attractive, short-term returns. During the meeting, industry leaders from the Greater Los Angeles area identified best practices, new opportunities, and existing resources in multiple topic areas to help Class B and C building owners and managers take charge of their building performance. The report summarizes industry leaders’ discussion of these topics:

  • Building Codes and Standards
  • Energy Efficiency and Energy Management Plans
  • Water Efficiency Opportunities
  • Financing Green Retrofits
  • New Building Technologies
  • Building Sustainability Trends
  • Climate Change
  • Other Industry Updates

The recently released reports highlight key outcomes of the roundtable discussions and integrate feedback from additional stakeholders during the months following the event. The findings and objectives of the reports are to:

  • Help utilities understand how to improve their regulatory and incentive programs by providing feedback about how they can best serve these critical yet often under-represented customers.
  • Encourage owners and managers of Class A, B and C properties to improve portfolio-wide energy and water efficiency and implement green building practices.
  • Inspire action to deepen environmental goals in the existing building sector by defining critical challenges and potential solutions, and by inviting key stakeholders to engage in the discussion.
  • Provide resources and education to service providers that are in a position to help building owners design and implement energy and water conservation strategies.

Utilities - energy efficiency, GHG emissions, green local government, municipal facilities, water efficiency, water energy - California Sustainability Alliance

The path to sustainability is difficult. Collaboration and joint efforts can help ease our journey. To this end, leaders from water and energy utilities as well as representatives from local governments of Southern California recently participated in a roundtable to discuss the opportunities to support each other in their efforts to promote energy and water efficiency. The 2013 Utility Sustainability Roundtable, the fourth such event, addressed three main topics: The Water-Energy Nexus, Aligning City Planning and Utility Incentive Cycles, and Cap-and-Trade.

Starting with the Water-Energy Nexus, attendees identified finding ways to present both water and energy efficiency opportunities to customers simultaneously as key to increasing participation in these programs. Such joint marketing must be specific to the customer and therefore requires water and energy suppliers to work together to raise awareness about savings opportunities and available incentives in their overlapping service territories. Joint water-energy audits have also proven to be a successful way to coordinate for increased customer participation.

The discussion then moved to Aligning City Planning and Utility Incentive Cycles. Coordinated communications between utilities and local governments may allow more trust to build and incentive funding to better enable scheduled system renovations in municipal buildings.

The last discussion topic related to an emerging topic: Cap-and-Trade. A forward-looking concept was presented that provides a framework by which utilities might be able to put additional funds toward the energy efficiency projects of local governments in return for the resulting emissions reductions.

The study also highlights a couple initiatives that would help move the ideas discussed forward. Download  the full report for more details.

Water Energy - on-site water recycling, recycled water, wastewater treatment, water distribution, water efficiency, water energy - California Sustainability Alliance
On-site water recycling holds potential water savings for commercial and municipal buildings.

California faces growing water scarcity concerns. Droughts pose continuous uncertainties to the water supply, but on-site water recycling could help alleviate the pressures of these uncertainties. On-site water recycling could contribute to increased water supply reliability as well as other environmental goals, such as reduced greenhouse gas emissions.

On-site water recycling systems are primarily one of two technology types - constructed wetlands or membrane bioreactors (MBR). For more information on these technologies, please refer to the Alliance’s report, “On-Site Water Generation: An Analysis of Options and Case Study” published December 2012.

The 2012 Alliance study found that on-site recycled water systems can supply water at lower energy intensity than imported water and desalination in Southern California. Nevertheless, most of the existing applications of recycled water are municipal-level wastewater treatment plants. On-site water recycling systems draw wastewater directly from a building’s toilets, showers, and laundry, treat it on-site, and reuse it to meet on-site non-potable needs, such as toilet flushing and irrigation. Installing these systems requires developers to not only manage the initial capital cost, but to confront a challenging regulatory environment. On-site water recycling is a relatively new concept and doesn’t fit neatly into existing regulatory frameworks focused on water-recycling and water- and waste-water treatment. Figuring out how to apply existing regulations – and understanding if the existing frameworks even apply – can be challenging for project developers as well as for those charged with preserving public health and safety. New regulatory frameworks must be developed to enable the installation of these systems.

As a follow-up to the 2012 Alliance Huntington Beach Study, the Alliance investigated further to verify the list of key regulatory hurdles for on-site water recycling and to identify potential solutions. A game-changer like revising the regulatory framework may take considerable time and resources, but the Alliance aims to also present good first steps. These are meant to be easier to implement in the short-term to generate momentum for those goals that are harder to achieve.

To first create awareness regarding the regulatory hurdles facing on-site water recycling system installations, the Alliance has released a new study entitled California On-Site Water Recycling: Policy Brief. This study documents the barriers to on-site water recycling systems and also and presents potential solutions. The policy brief focuses on the following barriers:

  • Lack of clear information about how to apply for permits;
  • Expensive daily coliform laboratory sampling and analysis
  • Stringent certification requirements for system operators

 

Key study conclusions include:

·      On-site recycled water systems are an emerging technology with the potential to play a role in helping manage California’s increasing water scarcity. 

·      Immediate actions should be taken to perform additional work on understanding potential regulatory models, estimating benefits, and initiating pilot activity.

·      An information portal should be designed so that potential developers of on-site water recycling systems and staff at key agencies have access to detailed information. 

·      One stretch goal to work towards is an exception to the Title 22 requirement for daily coliform sampling for on-site water recycling systems with a track-record of high water quality.

The study also highlights a number of case studies as examples of on-site water recycling. Download  the full report for more details.

Alliance News - economy, environmental affairs, environmental justice, green business, sustainable landscaping, water conservation, water efficiency, water energy - California Sustainability Alliance

On July 18, the water and environmental industries lost one of its leaders. The California Sustainability Alliance (Alliance) joins the many others mourning the loss of Lillian Kawasaki, who passed away on that day.

Ms. Kawasaki was a founding member of the Alliance’s Advisory Committee and offered invaluable advice on the organization’s start and early development. We will miss her wisdom and support, and will strive to keep her commitment to the environment and sustainability alive in the Alliance’s work.

Craig McDonald, Managing Director for Navigant Consulting and Project Director of the Alliance summed up Ms. Kawasaki’s influence: “Lillian’s insight, leadership, and vast knowledge of the water energy landscape was essential in shaping the Alliance’s great work in these fields.”

Highlights of Ms. Kawasaki career include launching the City of Los Angeles’ Environmental Affairs Department, heading the city Community Development Department and serving as assistant general manager of environmental affairs and economic development for the Los Angeles Department of Water and Power. Additionally, she was a member of numerous state and federal water policy committees during the course of her career, serving on the board of the Water Replenishment District (WRD) of Southern California and such professional organizations as the Association of Women in Water, Energy and Environment.

For more on Ms. Kawasaki’s remarkable life and commitment to public service and the environment, see her obituary in the Los Angeles Times.

Water Energy - on-site water generation, recycled water, wastewater treatment, water distribution, water efficiency, water energy, water loss control - California Sustainability Alliance

 

California water supplies are stressed as a result of decreasing supply and increasing demand.  While conservation and efficiency are the most cost-effective solutions, they may not completely solve the problem. Consequently, California water planners are considering multiple alternate water supply options including:

  • Desalination
  • Brackish water treatment
  • Rainwater harvesting (storm water capture)
  • Recycled water

Of these, water recycling is the only option that is applicable across the entire state and which can produce a relatively consistent resource regardless of the season or weather.  Wherever there is a wastewater treatment plant there is an opportunity to generate a local supply of recycled water.

Indeed, generating recycled water is not a challenge, distributing it is.  A major barrier to implementing a successful regional recycled water system is the cost of distribution pipelines. Typically a network of distribution pipelines and pump stations is needed to connect existing municipal water reclamation plants to potential recycled water customers.  Constructing these distribution systems can be expensive ($2-4 million per mile), especially in heavily developed areas such as Southern California. As a result, excess recycled water supply generated by large centralized plants cannot always be used cost-effectively. The Alliance’s 2008 report on recycled water shows that enough existing recycled water supply to meet all of Southern California’s projected increase in water use through 2030 is currently being released to streams and the ocean without benefit.

Recycled water can be implemented on a smaller scale; generating water in the same location as its demand eliminates the need for expensive distribution systems. Additionally, water supply and conveyance accounts for the majority of energy use by the state’s water infrastructure - imported water is among the most energy intensive (especially in Southern California).  On-site water generation has the potential to not only conserve water also save embedded energy in water.

To better understand the opportunity for on-site water generation, the Alliance has released a new study entitled On-Site Water Generation: An Analysis of Options and Case Study The study documents the characteristics of on-site water generation systems and also conducts a detailed cost benefit analysis for a representative case study on the City of Huntington Beach, California.Specifically the studyexplores:

  • Types of technologies available to provide on-site water generation
  • Costs and benefit analysis of the on-site water generation options
  • Primary market barriers to technology adoption.

Key study conclusions include:

  • On-site recycled water systems can supply water at lower energy intensity than imported water and desalination in Southern California. 
  • On-site Recycled water systems are most cost-effective in larger capacities. 
  • On-site water recycling relies on a consistent supply of wastewater and thus can provide more water than rainwater harvesting in Southern California

The study also discusses a number of recommendations for California policy-makers to stimulate the production and use of on-site water generation. Download  the full report for more details.
