Green Buildings:The Future of Sustainable Living

The objective of this research project was fulfilled through creation of a contemporary home,that of which undeniably projects modernization due to key LEED(leadership in energy and environmental design)features.Design of this project was carefully supervised by the civil engineering department at California State University,Northridge.The design incorporates a 3-story single-family home with a steel infrastructure.These design properties had a positive impact in LEED specific adjustments which assisted with the overall increase in sustainability.The six civil engineering senior students were able to successfully create a cost analysis and compare the benefits of a LEED incorporated design as opposed to a standard residential home.The difference between the two is evident as the highly sustainable building resulted in a 7.6%increase in overall cost.However,as the savings in energy progress over a 9-year period,the home will inevitably reduce the overall cost to the owner.This research project aided in allowing this diverse team of students to be exposed to real life scenarios,with incorporation of their knowledge acquired from the past 4 years.The diversity and teamwork of this group allowed for equal opportunities of innovation and leadership.Skills such as proper communication and critical thinking will significantly impact them as they progress in their careers as civil engineers.

Smart Building Design to Improve the Energy Consumption at an Office Room

Buildings are becoming smarter as a result of a variety of advanced technologies that enable energy management, optimal space utilization, and smart surveillance for safety, among other things. Energy-efficient smart building ideas and execution are of great interest and top priority due to the building’s occupants’ misused and high-power consumption. This paper addresses the design and execution of an energy management system that includes a solar power system for generating power for the building’s needs and a PIR-based automation system for efficient power use. This project was carried out at the Military Technological College (MTC) in Muscat, in the system engineering department’s offices. This project seeks to generate power for the building’s energy needs using solar photovoltaic panels and reduce energy consumption within the office using a PIR-based automation system. The results demonstrate that after the breakeven point (the time it takes to recoup the initial investment), it can provide power to the building for another 17 years. The calculations and practical results presented in this study approve that the system is extremely helpful.

Global technological advancement and challenges of glazed window,facade system and vertical greenery-based energy savings in buildings:A comprehensive review

There are many factors that have a major influence on reducing the energy expenditure in building sector.This research aims at qualitative and quantitative assessment of those factors such as double glazed windows,ver-tical greenery systems(VGS),integrating of semi-transparent photovoltaic device with architectural design of buildings,energy saving by using heat reflecting coating,passive climate control methods,energy saving by shading,building energy performance enhancement by using optimisation technique,double skin green facade,etc.through a holistic and thematic approach.Amongst the aforesaid techniques,VGS is found the most reliable,efficient and sustainable solution.Attractive VGS can improve the urban environment,increase biodiversity,mit-igate pollution also results economic benefit of the buildings as like as energy savings and decreasing surface temperature.Four fundamental energy saving methods are used in VGS which are considered as passive energy saving mechanism.Firstly,interception of solar radiation due to the shadow risen by the vegetation;secondly,vegetation also provides thermal insulation;thirdly,plants evapotranspiration helps for evaporative cooling of building;finally,building blockage makes a variation of wind effect on building.The peak cooling load of ivy coated green building wall has been reduced by 28%.If a VGS is installed without windows and building fac-ing on west,east,south and north correspondingly,the reduction in the cooling load capacity of the building is observed to be up to 20,18,8 and 5%,respectively.Very high thermally resistive glazed areas on building envelope can be secured via thin film PV glazing and vacuum glazing products with an average U-value of 1.1 and 0.4 W/m 2 K,respectively.Energy use policies are also helpful to improve energy consumption scenario of buildings.For developing more energy-efficient,sustainable and eco-friendly buildings,these techniques might be helpful for the building designers and architects.

Electrochromism-induced adaptive fresh air pre-handling system for building energy saving

Building fresh air supply needs to meet certain regulations and fit people’s ever-growing indoor air quality de-mand.However,fresh air handling requires huge energy consumption that goes against the goal of net-zero energy buildings.Thus,in this work,an adaptive fresh air pre-handling system is designed to reduce the cool-ing and heating loads of HVAC system.The sky-facing surface of the system uses electrochromic mechanism to manipulate the optical properties and thus make full use of solar energy(solar heating)and deep space cold source(radiative cooling)by switching between heating and cooling modes.In the cooling mode,the sky-facing surface shows a transmittance of down to zero,while the reflectance is high at 0.89 on average.In the heating mode,the electrochromic glass is highly transparent,allowing the sunlight to reach the solar heat absorber.To obtain the energy-saving potential under different climates,six cities were selected from various climate regions in China.Results show that the adaptive fresh air pre-handling system can be effective in up to 55.4%time of a year.The maximum energy-saving ratios for medium office,warehouse,and single-family house can reach up to 11.52%,26.62%,and 18.29%,respectively.In addition,the system shows multi-climate adaptability and broad application scenarios,making it a potential solution to building energy saving.
