Small and medium commercial buildings account for nearly half of the energy consumed by in United States. While retrofits can significantly reduce building consumption, buildings’ owners often lack capital experience to perform detailed audits retrofit assessments. The purpose this paper is introduce a low-investment, bottom-up simplified methodology identifying opportunities that benefit small sized office In particular, addresses on university campus as proof-of-concept other owner-operators have facilities their portfolio. consists an eight-step framework using publicly-available tools. opportunity assessments are not new, low-cost analyze consumption identify represents contribution knowledge. A Arizona served case study validate methodology. showed maximum potential reduction estimated 50%, but figure varies based types (deep versus light), conservation measures selected implemented, invested resources, interactive effects between measures. This extensible utility data would like themselves.

A comprehensive investigation regarding the hygrothermal behavior of a constructive solution containing phase change materials (PCMs) was performed on full-scale test cell, divided into two similar compartments. This involved monitoring (indoor air temperature) compartments, in which one had PCM incorporated floor mortar. The main goal this research to investigate potential kind for overheating mitigation. numerical study conducted using EnergyPlus® software (version 9.0), exploring different natural ventilation flow rates gauge novel solution’s reduce rates. results from studies revealed prolonged periods thermal discomfort both cells, particularly overheating. However, it proven that application cells led reduction almost 10 °C maximum peak temperature. In simulation analysis, increase rate linear decrease hours up renovation per hour, and then reductions were attenuated.

Nowadays, with the rapid growth of internet things (IoT), massive amounts time series data are being generated. Time play an important role in scientific and technological research for conducting experiments studies to obtain solid convincing results. However, due privacy restrictions, limited access is always obstacle. Moreover, available open source often not suitable because a small quantity insufficient dimensionality complexity. Therefore, generation has become imperative promising solution. In this paper, we provide overview classical state-of-the-art methods IoT. We classify into four major categories: rule-based methods, simulation-model-based traditional machine-learning-based deep-learning-based methods. For each category, first illustrate its characteristics then describe principles mechanisms Finally, summarize challenges future directions The systematic classification evaluation will be valuable reference researchers field.

Sensing and cognition by homeowners technicians for home maintenance are prime examples of human–building interaction. Damage, decay, pest infestation present signals that humans interpret then act upon to remedy mitigate. The process has direct effects on sustainability economic vitality, as well the health well-being building occupants. While practices date back antiquity, they readily submit augmentation improvement with modern technologies. This paper describes use networked smart technologies embedded machine learning (ML) presented in electronic formats better inform occupants about safety issues, recommend courses remedial action. demonstrated include robotic sensing confined areas, LiDAR scans structural shape deformation, moisture gas sensing, water leak detection, network ML, augmented reality interfaces multi-user teaming capabilities. sensor information passes through a private local dynamic processors neural pattern recognition capabilities abstract information, which feeds conventional device interfaces. system serves testbed demonstrator technologies, what can be termed Home Maintenance 4.0.

Temperature is the main driver of bridge response. It continuously applied and may have complex distributions across bridge. Daily temperature loads force bridges to undergo deformations that are larger than or equal peak-to-peak traffic loads. Bridge thermal response must therefore be accounted for when performing load rating condition assessment. This study assesses importance characterizing separating it from traffic-induced Numerical replicas (i.e., fine element models) a steel girder generated validate proposed methodology. Firstly, variety distribution scenarios, such as those resulting extreme weather conditions due climate change, modelled. Then, nominal scenarios simulated, characterized. Finally, damage modelled reduction in material stiffness corrosion. different before after introduction damage; however, can only correctly quantified accurately for.

Oil is one of the main resources used by all countries in world. The ever-growing demand for oil and products forces companies to increase production refining. In order net profit, producing are constantly upgrading equipment, improving technologies, preparing further processing. When considering elements primary refining difficult conditions, such as hard-to-reach or remote locations, developers face strict limitations energy dimensions. Therefore, use traditional systems causes a number difficulties, significantly reducing efficiency. this study, authors solve problem characteristics separation process. their work, analyzed columns distillation, identified shortcomings technological process, searched solutions.

Windows in new buildings Korea are equipped with double or triple glazing, a low-E coating, and gas injection between the panes of glass, accordance regulations for reinforced insulation windows. However, these windows have certain issues, such as thermal transmittance variations injected leakage. In this study, we investigated current status double-glazed filled argon analyzed actual deterioration degree terms performance via field experiments simulations. Accordingly, manufactured 26-millimeter window test specimen conducted tests KS F 2278 standard. The results indicated that decreased by 10.9% when filling rate was reduced from 95% to 0%. simulation showed were insulated using only glazing 22.6% decrease rate; also 13.6%. A comprehensive analysis surveys simulations predicted 92% probability would be below 65% two years after completion, addition ~4.3% performance.
