District Energy in Chile

District Energy in Chile

United Nations Environment Program. In 2017 Stephen completed a “Rapid Assessment” to find ways to reduce air pollution and reduce greenhouse gas emissions caused by burning firewood to heat buildings in Chile. The assessments included the City of Temuco and the Santiago suburb of Renca. The work was part of United Nations Environment’s District Energy in Cities Initiative, and was completed under contract to the Sustainability Solutions Group. In the community of Temuco, the challenge is that 93% of the air pollution comes from burning firewood for heat in single homes. Current heating practices cause significant health issues, as well as other forms of suffering such as energy poverty. These homes are distributed over a wide area of the city, and the assessment...

The Time Value of Carbon

The Time Value of Carbon

The Time Value of Carbon. Stephen was the lead author of the report The Time Value of Carbon: Smart Strategies to Accelerate Emission Reductions, which was published by the Chartered Professional Accountants of Canada in 2017. The report describes the strong effects on climate change of Near-term Climate Forcers such as methane and HFCs, and explains how current greenhouse gas accounting and reporting methods underestimate these effects. For example, the current greenhouse gas reporting practice is to account for the effects on climate of all greenhouse gasses over a 100-year time horizon. The choice of 100 years is arbitrary, however, and masks the very strong near-term effects on climate of gases with much shorter lifespans. Over a 20-year time-frame, methane...

Integrated Resource Recovery Analysis

Integrated Resource Recovery Analysis. In 2016, Stephen completed an Integrated Resource Recovery Analysis under contract to the Sustainability Solutions Group, to find opportunities to recover resources from waste in the Region of Waterloo. The Analysis compared options for the 100,000 tonnes per year of organic waste available in the region, and uncovered the following hybrid resource recovery concept: Organic waste could be diverted to a “Regional Bioenergy Centre”, where it would be processed in an anaerobic digester to produce biomethane and fertilizer which would be sold to generate revenues. If the Regional Bioenergy Centre is located near an existing industrial organization, it could be possible to use waste industrial energy to heat the digester as a...

Resources from Waste

Province of British Columbia, 2014. Resources from Waste Policy Analysis. In collaboration with the Sustainability Solutions Group, Stephen completed an analysis of options for recovering energy and other resources from solid waste. The clients for the study were the Ministry of Environment, Ministry of Energy and Mines, and the Ministry of Community, Sport, and Cultural Development, and the analysis was completed in three parts. The first part of the analysis addressed the question: How can we compare the environmental, economic, and social aspects of different solid waste management options? The analysis compared five solid waste management “archetypes” on the basis of environmental aspects (greenhouse gas emissions, criteria air contaminants), social aspects...

Project – Plan4DE

Project – Plan4DE

District energy is thousands of years old, and common in Europe. Given its many benefits, including greenhouse gas reductions, how can we foster its use elsewhere? Between 2014 and 2016 Farallon was part of a team that developed the Plan4DE, a modelling tool to accelerate district energy. Plan4DE is an interactive model, a kind of flight simulator for district energy planning. The model keeps the technical analysis in the background, and shows planners, modelers and decision-makers how they can optimize the design of a community for district energy. Users can see the effects of changing building density, building diversity (e.g. mixing commercial and residential in a community), energy efficiency, and multiple other factors on the viability of district energy....

City of Courtenay District Energy Study

City of Courtenay District Energy Study

In 2012 Farallon was engaged by the City of Courtenay to study the feasibility of a district energy system which could replace fossil fuels in the North Island College campus, the Comox Valley Recreation Centre, and the planned Comox Valley Hospital in Courtenay. Farallon hired FVB Energy Inc. for this study, which concluded that a district energy system would be viable if its development is coordinated with the design of the planned Comox Valley Hospital.
