Ground Source

Given the growing interest in ground source heat pump and distributed heating installations in general for the reduction of greenhouse gas emissions, technology implementation planning can benefit from the simultaneous consideration of building renovations. Here, a method for identifying and evaluating scenarios based on cost and greenhouse gas emissions is presented. The method is demonstrated for a case study in Vaasa Finland. The case study considers the insulation of the walls, roof, and base floor and the replacement of windows based on 2003 and 2010 Finnish building codes simultaneously with the possible replacement of existing heat sources with ground source heat pumps. Estimates of changes in heat demand for consecutive renovations are combined with data on renovation, installation, heating costs, and life cycle greenhouse gas emissions data for the current and proposed heat sources. Preferred scenarios are identified and evaluated by building type, construction decade, and current heating source. The results are then placed within the contexts of the Vaasa building stock and policy theory.

The Impact

In Sweden, 90% of multifamily buildings utilize district heat and a large portion is in need of renovation. The aim is to analyze the impact of renovating a multifamily building stock in a district heating and cooling system, in terms of primary energy savings, peak power demands, electricity demand and production, and greenhouse gas emissions on local and global levels. The study analyzes scenarios regarding measures on the building envelope, ventilation, and substitution from district heat to ground source heat pump. The results indicate improved energy performance for all scenarios, ranging from 11% to 56%. Moreover, the scenarios present a reduction of fossil fuel use and reduced peak power demand in the district heating and cooling system ranging from 1 MW to 13 MW, corresponding to 4–48 W/m2 heated building area. However, the study concludes that scenarios including a ground source heat pump generate significantly higher global greenhouse gas emissions relative to scenarios including district heating. Furthermore, in a future fossil-free district heating and cooling system, a reduction in primary energy use will lead to a local reduction of emissions along with a positive effect on global greenhouse gas emissions, outperforming measures with a ground source heat pump.

Institute Of Technology

The British Columbia Institute of Technology (BCIT) is Canada's premier polytechnic. In 2008, BCIT partnered with its local electricity utility to hire a full-time energy manager. The following year, BCIT's School of Construction and the Environment initiated a campus-as-living-lab of sustainability project called Factor Four in the seven buildings it occupies on BCIT's main campus in Burnaby. The purpose was to explore whether a four-fold (75%) reduction in materials and energy use could be achieved without compromising service levels. By 2016, the project achieved a 50% reduction in energy use and associated greenhouse gas emissions. Factor Four attracted over four million dollars in funding, engaged over 250 students from 12 educational programs, and produced over $200,000 savings annually. In 2017, BCIT set an ambitious target to reduce its annual greenhouse gas emissions 33% below 2007 levels by 2023, and 80% by 2050, across all five of its campuses. BCIT’s ultimate goal is to become both greenhouse gas neutral and a net energy producer. By setting ambitious targets and systematically implementing energy efficiency improvements, utilizing waste-heat exchange, fuel switching, and developing on-site renewable energy, BCIT is on track to achieving its energy management and climate change goals.

Class Theory

<p>The Earth’s population of seven billion consume varying amounts of planetary resources with varying impacts on the environment.  We combine the analytical tools offered by the socio-ecological metabolism and class theory and propose a novel social stratification theory to identify the differences and hot spots in individual resource and energy use. The theory is applied to German society and we use per capita greenhouse gas emissions as a proxy for resource and energy use. We use socio-metabolic profiles of individuals from an economic, social and cultural perspective to investigate resource intensive lifestyles. The results show large disparities and inequalities in emission patterns in German society. For example, the greenhouse gas emissions in the lowest and highest emission classes can differ by a magnitude of ten. Income, education, age, gender and regional differences (FRG vs. GDR) result in distinct emission profiles. Class differentiation is also noted as economic, cultural and social factors influence individual carbon footprints. We also analyze the role of digital technologies, regarding resource and energy consumption, as a proxy for cultural capital. Highlighting inequalities within societies is a step towards downscaling carbon emission reduction targets that are key to avoid transgressing climate change planetary boundary. We discuss the results in the context of climate policy implications as well as behavioral changes that are needed to meet climate policy objectives.</p>
