Energy and resource efficiency are promoted as the main drivers to create an environmentally less harmful economy [13].Besides, the EU proposals for reducing CO 2 emissions in the use phase, the automotive industry, for example, is aiming at ECO-innovations of engine, powertrain and part related technologies. Companies become more and more aware …

An empirical Bayesian (EB) approach, incorporated a probability-based mixed-effects energy model and Monte Carlo Markov chain simulation, was developed to predict and benchmark building energy use intensity (EUI) for space heating, using the metering data of 2020 stochastically sampled district heating substations from a municipal utility database.

ITP relies on analytical studies to identify large energy reduction opportunities in energy-intensive industries and uses these results to guide its R&D portfolio. One facet of energy analysis includes energy bandwidth studies which focus on a particular industry and analyze the energy-saving …

A survey of the comminution energy requirements of gold and copper producing mines has been conducted to provide reliable benchmarking data which can be used to …

The benchmarking was done using a special technique based on the Lorenz curve, which was compared with two competing methods. The Lorenz curve method was proved to be the most adequate one among the three. It can extract the energy benchmarks based on the distribution rules of heating energy use intensity in relation to the cumulative building ...

Through energy benchmarking, building auditing can then be pursued more effectively when determining which buildings are inefficiently using energy. Harvard is currently developing energy benchmarks for each of our major building types (e.g. "office", "classroom", etc.). More information on this process will be available in the coming months.

"benchmarking" refers to developing and using metrics to compare the energy or emissions intensity of industrial facilities. Benchmarks are primarily used to compare facilities within the same sector, but can also be used to identify best practices across sectors where common process units, such as boilers, are used.

The research utilises industrial data from a 2850 tonne per day capacity dry process cement plant. Key energy and emissions parameters, including thermal and electrical energy intensity, recovered energy and CO 2 intensity, are computed per tonne of cement produced along with capacity utilisation across major process stages including raw ...

Currently, most data-driven building energy benchmarking studies conduct open-source datasets released by multiple institutes and utilize primary building types or urban-specific climate regions for classification and energy use prediction [9, 10].However, the current data-driven approach has three major challenges: lack of monthly energy data, trade-offs between …

Because of their energy intensity, mining operations tend to emit high levels of greenhouse gases, ... even from reliable sources such as Natural Resource Canada and U.S. benchmarking studies ...

As illustrated in Fig. 1, energy benchmarking is expected to play a more critical role in increasing energy awareness by supporting the above approaches [17]. Conceptually, energy benchmarking defines a process of measuring an entity's energy consumption against a yardstick that represents the standard or optimal consumption of that entity [18].

Retail stores are amongst the building typologies with the highest carbon and energy intensity, placing this segment in the top 10 most carbon-intensive business sectors [1].In addition, retail stores are responsible for 9% of the European building stock [2] with a standard energy intensity (EI) that ranges from 500 to 1000 kWh/m 2 /y, corresponding to three times …

Efficiencies of the energy intensity of each process block across the set of plants are varied in case 1 and case 3, and are kept at for case 2. An efficiency of is comparable to the energy intensity of each process block presented in Table 3. For case 2, the amount of outside whey is varied while keeping the efficiency of each ...

Specific energy consumption (SEC) is a common KPI used to benchmark and measure energy efficiency in industrial processes (Estrada et al., 2018; Sathitbun-anan et al., 2014; Smyth & Nesbitt, 2014; Tantisattayakul et al., 2016).

In this study, we (i) provide the first bottom-up assessment of the mining industry's final energy consumption globally (1971–2015), (ii) use 1.5°C consistent socio-economic …

Other than the country or regional level, energy benchmarking programs also apply at the urban scale: in New York City (NYC), the energy disclosure program, which mandates energy audits, reduced energy use by 2.5 % for residential buildings and 4.9 % for office buildings (Kontokosta et al., 2020).According to Palmer and Walls (2015), the building energy …

Based on an analysis of China's energy situation and energy efficiency benchmarking, this paper uses product-based benchmarking and process-based benchmarking to create a benchmarking methodology which has the following properties: a unified energy efficiency benchmarking indicator system developed in accordance with related standards.

The resulting energy benchmarking can be called process or process-step energy benchmarking [7], [16], depending on the definition of the process or process-steps. In this paper, we use process blocks to describe relatively aggregate sub-processes, and process-steps for disaggregated sub-processes within a process block.

The correlation found between EI and CI indicates that low energy consumption leads to low greenhouse gas (GHG) emissions. CI variability resulted mostly of energy-efficiency strategies, of the energy production process and of GHG emissions from refrigeration systems. EI variability resulted mostly from store typology, volume and usage.
