“…Retrofit of office buildings in Italy was found to reduce the primary energy by at least 40% [24]. Retrofit energy saving in four existing class A commercial office building downtown Toronto in Canada reached 0.9% to 18% energy saving with LEED and BOMA certification [25]. Energy retrofit measures allowed 29-31% electricity saving and 19-32% natural gas saving in low-rise office building in Edmonton, Ottawa and Vancouver [12].…”

This case study evaluates the best energy efficiency measures of an existing two-story office building from the late 1960s located in Vancouver. Natural gas was used for heating and electricity was used for lighting, cooling and other needs. The building was simulated to match both metered data and bills. The energy model allowed identifying the parameters to reduce the energy consumption and mitigate the impact on CO2-eq emissions. On-site renewable energy supply was simulated. The return on investment (ROI) of the retrofit strategies (building envelope and renewable energy) was calculated to determine the profitability. From the parametric study, the insulation of the wall and roof, the airtightness and window replacement have the most impact on energy saving and allowed reducing 45% of the total annual energy consumed. These improvements can save more than 70 tons of CO2-eq per year from reducing the natural gas consumption. The return on investment of upgrading the building envelope was 7.7 years in Vancouver. Net zero energy building performance was possible with the addition of photovoltaic solar panel and solar heating to supply the total energy needs of the building, with an ROI of 11.6 years. If we changed the building location to Montreal, the same optimized building envelope reduces the energy consumption by 39%, and the energy saving increases to 56% when using the electric heating system usually already in place. Overall, building envelope upgrades are solutions to consider to improve energy saving in northern climate.

“…That has become possible owing to the numerous federal and regional programmes providing grants, credits, and financing to stimulate the implementation of energy-saving technologies. However, currently, the priority of Canadian government is shifting from direct financing and crediting to the programmes stimulating dissemination of information concerning the data, tools for their analysis, and demand control programmes being financed by power corporations and supported by regional bodies of state authority (Carlson & Pressnail, 2018;Maiorano, 2018;Maiorano, 2019).…”

Purpose is the analysis of world practice of applying the best available techniques to increase energy saving and energy efficiency of mining enterprises being the important factor of the economic development. Methods. The research methodology is based on the scientific approaches: historical-evolutionary, interdisciplinary, integration, process, and situational. Methods of retrospective, categorical, and system analysis as well as modeling have been applied. The analysis was performed on the basis of both initial information sources (original texts of legislative documents, strategies) and material of the international analytical organizations (International Energy Agency, World Bank) as well as the data of official statistical records. Findings. For the first time, different variants of the best available techniques in Japan, the USA, and the EU have been analyzed as well as the role of a state in applying institutional measures of energy efficiency support, including mining complex, and prospects of its use in the Russian Federation. It has been determined that energy efficiency is the effective and economically feasible tool in reaching sustainable development of the national economy. It has been demonstrated that energy saving and increased energy efficiency may reduce the needs in investment, raise industrial competitiveness and consumer welfare as well as improve environmental protection owing to the reduced greenhouse gas emissions and decreased air pollution. Energy efficiency growth has direct effect upon the industrial competitiveness; it can be achieved by means of innovations. Originality. Emphasis has been put on the key scientific and technical aspects and approaches stimulating increased energy efficiency in the developed countries under the effect of strong, coordinated, and consistent national policy in different sectors of economy. Practical implications. The carried-out analysis is useful in terms of the innovative and technological development of different industries of the Russian Federation in the context of its complicated cooperation with European countries and the USA, dependence on foreign technologies, and limited access to them.

“…Some argue that the potential to address climate change by green technology is underestimated. Action is needed both in new construction and deep energy retrofits in existing buildings [2][3][4][5]. It is especially important in Canada where the building sector accounts for 12 percent of overall greenhouse gas (GHG) emissions [6].…”

Decisions by Key Office Building Stakeholders to Build or Retrofit Green in Toronto’s Urban Core

The environmental impact of greenhouse gas emissions from buildings—especially in global cities such as Toronto—is well documented. Green mitigation of new and existing buildings has also been researched. Few studies, however, have focused on the decision to build or retrofit green. Are key stakeholders in Toronto’s office building sector aligning their decisions to achieve sustainable environmental goals? Do they support LEED certification regardless of the impact on market valuation? Are tenants willing to pay higher rents in LEED office buildings? The study first obtained data on 16 LEED and 52 conventional buildings to determine if LEED certification has a significant impact on net asking rent. Pearson correlation and linear regression analysis did not find LEED certification to be statistically significant in explaining the variance in net asking rent (market value). The second stage included interviews with senior executives engaged in Toronto’s office building sector. The expert informtabants were asked to assess if financial drivers are the deciding factor in decisions to pursue LEED certification. They concurred that LEED certification is not the primary driver. It is a combination of numerous factors that overall have an impact on a firm’s financial bottom line.
