applications cite{Garg12,Tiwari02}. Solar air heater (SAH) is one of the promising solar thermal technologies. Other added benefits of SAH are simpler in design, easy to install and cheaper to operate cite{Tiwari02, MNRE,Duffie13}. Unlike solar photovoltaics, the SAHs produce heated air directly from solar radiation with no complex energy…

6.3.2 Energy Payback Time (EPBT) It is the required time to payback the embodied energy of the product. It is evaluated as [142]: (6.1) 6.3.3 CO2 Emission Watt et al., have reported that, the emission of average CO2 is approximately equivalent of 0.98 kg of CO2/kWh in the electricity generated by coal [143]. The CO2 emission per year can be calculated as [144] (6.2) 6.3.4 Carbon Mitigation and Earned Carbon Credit The mitigation of carbon dioxide (CO2) is used to measure the climate change…

Electrochromism is the reversible change in optical properties when a material is electrochemically oxidized or reduced[6] and can be simply represented by Equation (1), where M+ can be H+, Li+, Na+ or K+ , 0 < x < 1, and e- are denoting electrons.[2] (transparent) WO3 + xM+ + xe- ↔ 2 MxWO3 (deep blue) ------------- Equation (1) An electrochromic system consists of an ion-containing material (electrolyte) that is of close proximity to the electrochromic layer and the transparent layers…

Costco Wholesale Corporation began in 1983 in Seattle, Washington. It is the second largest retailer store in the nation and serves too many communities. Employing over 135,000 full and part time employees in the United States alone, and around 200,000 employees worldwide. A corporation that is efficient in operations, has unmatched savings and is accessible through membership has a vision to give the customer a low efficient discount price and still continue to financially make a profit. The…

Hyatt Joins Forces with Bloom Energy, Emphasizing Strong Commitment to Sustainability and Innovation • Hyatt Hotels Corporation announced its new relationship with Bloom Energy • Hyatt Regency Greenwich will receive company’s first 500 kW fuel cell • Fuel cell will provide up to 75 percent of hotel’s energy load, generating significant cost savings • Hotel will reduce its carbon emissions by 40 percent by generating its own electricity on-site • Hyatt’s investment in fuel cell technology…

I am writing this letter to indicate my interest in the open Dean position at University of Maryland College of Architecture, Planning and Preservation. The role is closely aligned to the work I have been engaged in through several years of university administration and participating in national leadership positions; and I believe I am a strong fit for the institution. I am excited to have an opportunity to enter into the conversation. Academic / Practice Preparation One of the reasons I…

environment. Competition is multi-faceted. The existence and potential growth of competitors are economic factors which are of primary importance in developing a firm’s strategy. The amount of competition versus cooperation between firms in the same field is partially a socio-cultural factor, while the government’s attitudes toward monopoly or oligopolistic agreement is a political factor. Top management must be lightly sensitive to each of these , particularly to the latter.…

mechanical stability on impact, light weight and significantly effective in the cost of manufacturing. Due to these alluring properties, organic polymers are becoming extremely important in applications such as transparent/flexible optoelectronics, photovoltaics, field-effect transistors, sensors, lasers and visible LEDs. In majority of these applications, potential use of organic polymers is in the form of anti-reflective coatings, optical adhesives, substrates, and micro lenses. The critical…

if not one of the best source of renewable energy. Solar energy is always reliable as the sun is always out and has the capability to produce enough energy to be stored even as it’s during night time or a cloudy day. Solar energy is from solar photovoltaic cells that have a negative and positive charge on the silicon beneath the slice of glass and as the photons of sunlight are collected by these cells, the electrons are separated which they are attracted to one side of the silicon, creating an…

Elizabeth Diller, the designer of the Roy and Diana Valegos Education Center, wanted to design a building that was not only a structurally powerful building, but an innovative, sustainable building that worked toward the goal of minimizing CUMC’s carbon footprint while reducing greenhouse gas emissions by 30% by 2025. The project was designed by Diller Scofidio + Renfio, an interdisciplinary design studio that mixes the knowledge from different areas of expertise like architecture, visual, and…
