Manufacturers have to adapt their product portfolio and lighting designers and installers have to figure out how the new light source will behave. A lot of research, studies and tests are being done to gain more knowledge when it comes to dealing with semiconductor light. By the end of this decade there will be significant improvements that are concentrated on the parameters and implementation of the LED. This development is very important but the really big challenge, when looking at lighting installations in general, is ELECTRONICS. The reason for this is that the weakest element in a system limits its overall performance. The life-time of electronic drivers is mainly determined by the use of electrolytic capacitors. The temperature degradation of these components will often reduce life-time under real conditions below the 50,000 hours that are expected of LEDs. In addition, the failure rates of the electronic modules, consisting of 50 to 100 single components, are not equal to the failure rates of single LEDs or LED strings. Electronics are even being challenged on a system level. The number of electronic ballasts for fluorescent lamps that can be connected to a circuit breaker is well defined. The problem is that the inrush or start-up currents are much higher now and those limits don’t correspond properly with the electronic LED drivers.

    The High Performance Home Manual

    THE HIGH PERFORMANCE HOME MANUAL THE HIGH PERFORMANCE HOME MANUAL This document, along with the detailed drawings, is presented to offer our clients a roadmap in developing an "High Performance" home. This is not necessarily a "Green" home and does not take into consideration air-quality. It focuses on resource efficiency, energy efficiency, water conservation, and "providing for the future"; all of which are a part of a “green” home design, but not exhaustive. In some instances, we have provided “preferred” options as well as less costly means of attaining a near "High Performance" home. IMPORTANT: It is important to note that this information (these parameters) and the related detailed drawings are specifically for homes that are to be built in Southwest Texas (primarily the "hill country" type climate). The Climate Zone is three (3). Site Design Features: • Heat Mitigation: a. Shade hardscape (drives, walks, etc.) with shade trees or such. b. Utilize turf pavers for drive and/or walks, patios, etc. Resource Efficiency: • Drip edge (eaves and gables): a. Minimizes wicking and water distribution off roof material, decking, and fascia. • Roof Water Discharge: a. Provide gutters and downspout system with splash blocks (or such) to carry water a minimum of five feet from foundation (or utilize water harvesting system – see below). • Finish Grade: a. Provide a minimum fall of six inches for each ten feet from edge of building. • Flashing (galvanized metal): a. Flash roof valleys. b. Flash deck/balcony to building intersections. c. Flash at roof-to-wall intersections and roof-to-chimney intersections. d. Provide a drip cap above windows and doors that are not flashed or protected by coverings like pent roofs or are recessed in the exterior wall at least 24 inches.
