Instant Hot Water vs. Recirculating System
Many folks confuse the very popular, on-demand water heater with what a recirculating system can only provide. An instant hot water system does what it says - heating water right when there is a request for hot water ie. when the hot water is turned on at a plumbing fixture. In other words, the water is not heated and stored, but instead heated as needed. However, if the sink or shower at which you want hot water is some distance from the instant hot water heater, then the hot water line still has to be drained of the remaining temperate water that has been sitting in the line cooling after it left the hot water heater. With an on-demand recirculating system that temperate water is recirculated back to the hot water heater instead of being pour down the drain. Then once the temperature of the water in the supply line reaches the desired pre-set temperature, it allows that faucet to open up and supply the hot water to the end user. Imagine the water savings when you no longer have to let all that cold water pass down the drain while you’re waiting for the hot water!!!
Elements of Green Building
Green Building is essentially about recognizing and better understanding the relationship building design has with the environment, and building occupants; and then ensuring that design maximizes human and environmental health. Though the green building knowledge base is vast, knowing a little about the following five topics will give you a decent understanding of green building.
Site Selection - a building's orientation to the sun, wind, and weather can significantly alter building energy use. Treating building sites with care can help improve or restore stressed eco-systems, improve drainage and quality of life for building occupants.
Energy Efficiency - The construction and operation of buildings accounts for 37% of all energy use and 68% of all electricity demand in the United States. By properly insulating and sealing homes, installing energy efficient heating, cooling, hot water systems, and appliances, and taking advantage of renewable energy sources like solar, wind, and geothermal we can dramatically reduce the buildings' impact on the environment including reducing buildings' contribution to global warming.
Water Conservation - Over 12% of our fresh water supply is consumed in buildings. By installing water saving faucets, toilets, and showerheads and by capturing and using rainwater and "grey" water from our roofs and tubs, we can significantly reduce our demand for fresh water.
Materials and Resources - Construction, both new and renovation, consumes large quantities of materials. Green building carefully considers the environmental impact of building materials. What is the product made of? Does it contain harmful or toxic chemicals? Does the product contain recycled content or can it be easily recycled? Can the product be harvested at a sustainable rate? These are some of the critical questions green builders must ask before choosing building materials.
Indoor Environmental Quality (IEQ) - Students perform better, workers are more productive, and occupants are generally happier and healthier in buildings with superior indoor environmental quality (IEQ). IEQ primarily considers daylight, air quality, and views (to the outside).
