The homeowners wish to incorporate green design. Discuss five techniques that the homeowners could adopt to make their home green.


Restatement: Five techniques that the homeowners could adopt to make their home a green building. 

Definition: A green building focuses on a whole system perspective, including energy conservation, resource-efficient building techniques and materi¬als, indoor air quality, water conservation, and designs that minimize waste while utilizing recycled materials. Green buildings are a product of a good design that minimizes a building's energy needs while reducing construction and maintenance costs over the life cycle of a building. 

Techniques 
•Solar collectors for space heating. 

•Solar collectors for water heating. 

•Photovoltaics to supply electrical energy. 

•Hybrid systems that incorporate more than one power source such as wind or microhydro. 

•Energy-efficient appliances (energy star: http://www.energystar.gov). 

•Products made from environmentally attractive materials, including products that reduce materials use. For example, drywall clips that eliminate the need for corner studs, salvaged materials, recycled materials (sprayed cellulose, a recycled material, used for insulation), products made from agricultural waste, and certi¬fied wood products that carry an FSC stamp, indicating they meet the high standards set by the Forestry Stewardship Council. 

•Products that do not contain toxins. For example, products that substitute for polyvinyl chloride (PVC), ozone-depleting chemicals, and conventional pres¬sure-treated lumber. 

•Products that reduce the environmental impacts of construction, renovation, and demolition. For example, erosion control products and exterior stains with low emissions of volatile organic compounds (VOCs). 

•Products that reduce the environmental impacts of building operation, includ¬ing products that reduce energy and water use, reduce the need for pesticide treatments (for example, physical termite barriers), or have unusual durability or require little maintenance. 

•Products that contribute to a safe, healthy indoor environment, including prod¬ucts that do not release significant pollutants (for example, low-VOC paints, caulks, and adhesives), products that remove indoor pollutants (for example, certain ventilation products), and products that warn inhabitants of health haz¬ards (for example, carbon monoxide detectors and lead-paint testing kits). 

•Superinsulated houses are constructed to be airtight, have a higher level of insu¬lation compared with conventional houses, and have a ventilation system to control air quality. 

•Green landscaping - landscaping that provides shade during summer and allows sunlight to warm the house during winter (deciduous trees). Large deciduous trees planted at least 15 to 25 feet away from a house on the south and west sides provide afternoon summer shade while still allowing cooling winds to pass through the tree canopy. Yet they also permit sun to pass through bare branches for solar gain in winter. In addition, they can reduce cooling costs by shading air¬conditioning units. Finally, plants that do not require a lot of water can be used.

Discuss the seven characteristics of useful information.

Discuss the seven characteristics of useful information. Answer: The seven characteristics of useful information are: relevant, reliable, complete, timely, understandable, verifiable and accessible. These characteristics are qualities that information should possess to be useful in a business environment. Briefly stated, in order for information to be useful it must be: 1) relevant, meaning that it reduces uncertainty and adds to the decision-making process; 2) reliable information is information that is free from error, and is accurate in its nature; 3) complete information is information that does not omit any important data, facts, or aspects about events or activities; 4) information is timely when it is fully available to enable the decision-making process to proceed; 5) understandable information must be both in an intelligible and useful format; 6) information is considered verifiable if two people, acting independently of each other, produce the same inform

Why have accounting software packages been designed with separate transaction modules?

Why have accounting software packages been designed with separate transaction modules? Answer: : Since every organization does not necessarily use all of the transaction cycles in its operations, it is to the advantage of the organization to be able to "pick and choose" from among various software modules that track and record different transaction cycles. For example, a law firm would have no need to implement a production cycle module. Also, the nature of a transaction cycle varies across the broad spectrum of business organizations. Again, a law firm would have a revenue cycle, but it would not involve the purchase, receipt, and payment for products or merchandise; likewise a retail store chain may not sell any consulting services to its customers.

A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D.

A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D. Design an experiment, based on the principles of diffusion and osmosis, that the assistant could use to determine which of the flasks contains each of the four unknown solutions. Include in your answer (a) a description of how you would set up and perform the experiment: (b) the results you would expect from your experiments: and (c) an explanation of those results based on the principles involved. (Be sure to clearly state the principles addressed in your discussion.)
