Designing With Feng Shui in Mind

Designing With Feng Shui in Mind Feng shui (pronounced fung shway) is a learned and intuitive art of understanding the energy of elements. The goal of this Chinese philosophy is harmony and balance, which some people have compared with the Western Classical ideals of symmetry and proportion. Feng is wind and shui is water. Danish architect Jà ¸rn Utzon combined these two forces of wind (feng) and water (shui) in his Australian masterpiece, the Sydney Opera House. Seen from this angle,  says Feng Shui Master Lam Kam Chuen, the whole structure has the quality of a craft with full sails: when the energy of the Wind and Water move together in certain directions, this ingenious structure draws that power to itself and to the city that surrounds it. Designers and decorators claim that they can feel the surrounding, universal energy called chi. But architects who incorporate the Eastern philosophy are not guided by intuition alone. The ancient art prescribes lengthy and complex rules that may strike modern homeowners as quirky. For example, your home should not be built at the end of a dead-end road. Round pillars are better than square. Ceilings should be high and well-lit. To further confuse the uninitiated, there are several different ways to practice feng shui: Use a compass or Lo-Pan to establish the most beneficial placement of roomsDraw on information from the Chinese horoscopeExamine the surrounding land forms, streets, streams and buildingsUse high-tech equipment to examine environmental health hazards, such as electromagnetic radiation and toxic materialsUse feng shui principles to help sell your houseUse some variation of a tool called the Ba-Gua an octagonal chart outlining the most favorable placement for roomsManipulate surrounding chi with appropriate colors or objects like a spherical sculpture Yet even the most baffling practices have a basis in common sense. For example, feng shui principles warn that a kitchen door should not face the stove. The reason? A person working at the stove may instinctively want to glance back at the door. This creates a feeling of unease, which can lead to accidents. Feng Shui and Architecture: Feng Shui teaches us how to create healthy harmonious environments, says Stanley Bartlett, who has used the centuries-old art to design homes and businesses. The ideas date back at least 3,000 years, yet a growing number of architects and decorators are integrating feng shui ideas with contemporary building design. For new construction, feng shui can be integrated into the design, but what about remodeling? The solution is the creative placement of objects, colors, and reflective materials. When the Trump International Hotel in New York City was remodeled in 1997, feng shui masters Pun-Yin and her father Tin-Sun installed a giant globe sculpture to divert the roundabout traffic energy from Columbus Circle away from the building. In fact, many architects and developers have enlisted the expertise of feng shui masters to add value to their properties. Everything in nature expresses its own energetic force, says Master Lam Kam Chuen. Recognizing this is essential to creating a living environment in which Yin and Yang are balanced. Despite the numerous complicated rules, feng shui adapts to many architectural styles. Indeed, the clean, uncluttered appearance may be your only clue that a home or office building was designed according to feng shui principles. Think of the shape of your house. If its square, a feng shui master may call it Earth, child of Fire and controller of Water. The shape itself expresses the supportive, secure, and stable quality of Earth, says Lam Kam Chuen. Warm tones of yellow and brown are ideal. Fire Shapes Master Lam Kam Chuen describes the famous triangular design of the Sydney Opera House in Australia as a Fire Shape. The irregular triangles of the Sydney Opera House lick the sky like flames, observes Maser Lam. Master Lam also calls St. Basils Cathedral in Moscow a Fire building, filled with an energy that could be as protective as your mother or as fierce as a mighty enemy. Another Fire structure is The Louvre Pyramid designed by Chinese-born architect I.M. Pei. It is a superb Fire structure, writes Master Lam, drawing down intense energy from the heavens- and making this site a prodigious attraction for visitors. It is perfectly balanced with the Water structure of the Louvre. Fire buildings are generally triangular in shape, like flames, while Water buildings are horizontal, like flowing water. Metal and Wood Shapes The architect shapes space with materials. Feng shui integrates and balances both shapes and materials. Round structures, like geodesic domes, have the energetic quality of Metal moving consistently and safely inward- the ideal design for shelters, according to Feng Shui Master Lam Kam Chuen. Rectangular buildings, like most skyscrapers, express growth, expansiveness, and power typical of Wood. Wood energy expands in all directions. In the vocabulary of feng shui, the word wood refers to the shape of the structure, not the building material. The tall, linear  Washington Monument may be described as a wood structure, with energy moving every which way.   Master Lam offers this assessment of the monument: Its spear-like power emanates in all direction, affecting the Capitol building of the Congress, the Supreme Court, and the White house. Like a mighty sword raised in the air, it is a constant, silent presence: those who live and work within its reach will often find themselves subject to internal disturbance and their ability to make decisions blocked. Earth Shapes and the Smudgers The American Southwest is an exciting juxtaposition of historic pueblo architecture and what many people consider tree-hugging modern ideas about ecology. A vibrant, local community of ecothinkers- people whose environmental thoughts direct their behaviors- have been associated with the area for decades. Frank Lloyd Wrights Experiment in Desert Living is perhaps the most famous example. It seems that this region has an unusual number of architects, builders, and designers committed to ecoversity- energy-efficient, earth-friendly, organic, sustainable design. What we call Southwest Desert Design today is known to combine futuristic thinking with a profound respect for ancient Native American concepts- not only building materials, like adobe, but also feng shui-like Native American activities such as smudging being incorporated into everyday life. Bottom Line on Feng Shui: So, if you are stuck in your career or have trouble in your love life, the root of your problems may be in the design of your home and the misguided energy that surrounds you. Professional feng shui design suggestions can only help, say practitioners of this ancient Chinese philosophy. One way to get your life in balance is to get your architecture in balance.

How Homogeneous Charge Compression Ignition Works

How Homogeneous Charge Compression Ignition Works In the quest for ever-improving fuel efficiency and emissions reduction, an old and very promising idea has found new life. HCCI (Homogeneous Charge Compression Ignition) technology has been around for a long time but has recently received renewed attention and enthusiasm. While the early years saw many insurmountable (at the time) obstacles whose answers would only come as sophisticated computer controlled electronics were developed and matured into reliable technologies, progress stalled. Time has, as it always does, worked its magic and nearly every problem has been solved. HCCI is an idea whose time has come with nearly all of the parts and pieces of technology and know-how in place to make a real go of it. What is HCCI? An HCCI engine is a mix of both conventional spark-ignition and diesel compression ignition technology. The blending of these two designs offers diesel-like high efficiency without the difficult- and expensive- to deal with NOx and particulate matter emissions. In its most basic form, it simply means that fuel (gasoline or E85) is homogeneously (thoroughly and completely) mixed with air in the combustion chamber (very similar to a regular spark-ignited gasoline engine), but with a very high proportion of air to fuel (lean mixture). As the engines piston reaches its highest point (top dead center) on the compression stroke, the air/fuel mixture auto-ignites (spontaneously and completely combusts with no spark plug assist) from compression heat, much like a diesel engine. The result is the best of both worlds: low fuel usage and low emissions. How Does HCCI Work? In an HCCI engine (which is based on the four-stroke Otto cycle), fuel delivery control is of paramount importance in controlling the combustion process. On the intake stroke, fuel is injected into each cylinders combustion chamber via fuel injectors mounted directly in the cylinder head. This is achieved independently from air induction which takes place through the intake plenum. By the end of the intake stroke, fuel and air have been fully introduced and mixed in the cylinders combustion chamber. As the piston begins to move back up during the compression stroke, heat begins to build in the combustion chamber. When the piston reaches the end of this stroke, sufficient heat has accumulated to cause the fuel/air mixture to spontaneously combust (no spark is necessary) and force the piston down for the power stroke. Unlike conventional spark engines (and even diesels), the combustion process is a lean, low temperature and flameless release of energy across the entire combustion chamber. The entire fuel mixture is burned simultaneously producing equivalent power, but using much less fuel and releasing far fewer emissions in the process. At the end of the power stroke, the piston reverses direction again and initiates the exhaust stroke, but before all of the exhaust gases can be evacuated, the exhaust valves close early, trapping some of the latent combustion heat. This heat is preserved, and a small quantity of fuel is injected into the combustion chamber for a pre-charge (to help control combustion temperatures and emissions) before the next intake stroke begins. Challenges for HCCI An ongoing developmental problem with HCCI engines is controlling the combustion process. In traditional spark engines, combustion timing is easily adjusted by the engine management control module changing the spark event and perhaps fuel delivery. Its not nearly so easy with HCCIs flameless combustion. Combustion chamber temperature and mixture composition must be tightly controlled within quickly changing and very narrow thresholds that include parameters such as cylinder pressure, engine load and RPMs and throttle position, ambient air temperature extremes and atmospheric pressure changes. Most of these conditions are compensated for with sensors and automatic adjustments to otherwise normally fixed actions. Included are individual cylinder pressure sensors, variable hydraulic valve lift and electromechanical phasers for camshaft timing. The trick isnt so much as getting these systems to work as it is getting them to work together, very quickly, and over many thousands of miles an d years of wear and tear. Perhaps just as challenging though will be the problem of keeping these advanced control systems affordable. Advantages of HCCI Lean combustion returns 15 percent increase in fuel efficiency over a conventional spark ignition engine.Cleaner combustion and lower emissions (especially NOx) than a conventional spark ignition engine.Compatible with gasoline as well as E85 (ethanol) fuel.Fuel is burned quicker and at lower temperatures, reducing heat energy loss compared to a conventional spark engine.Throttleless induction system eliminates frictional pumping losses incurred in traditional (throttle body) spark engines. Disadvantages of HCCI High cylinder pressures require stronger (and more expensive) engine construction.More limited power range than a conventional spark engine.The many phases of combustion characteristics are difficult (and more expensive) to control. It is clear that HCCI technology offers superior fuel efficiency and emissions control compared to the conventional tried-and-true spark ignition gasoline engine. Whats not-so-certain yet is the ability of these engines to deliver these characteristics inexpensively, and, probably more importantly, reliably over the life of the vehicle. Continued advancements in electronic controls have brought HCCI to the precipice of workable reality, and further refinements will be necessary to push it over the edge into everyday production vehicles.
