Your home's windows, walls, and floors can be designed to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design or climatic design because, unlike active solar heating systems, it doesn't involve the use of mechanical and electrical devices, such as pumps, fans or electrical controls to move the solar heat.
When it comes to lighting, the biggest challenge is to balance your practical needs with the vast array of choices for lighting your home and exterior spaces. Advances in lighting design, techniques and products have made it possible to create any effect imaginable with the proper type of light, placement, and fixtures. These three areas form the heart of lighting design and give homeowners the keys to designing welcoming, functional spaces that reflect their taste and individuality.
Looking at Lighting Needs
Deciding what to light depends on what you use light for: performing household tasks, accenting art or architecture, creating a certain mood or ambiance. Analyze the spaces in your home, because how you use them will drive your decisions about how to light given areas and what to light them with. Keep in mind that there are three basic techniques for lighting that are used by all the pros. Ambient lighting provides general, overall illumination, promotes safe, easy movement, defines the space, and makes a visual statement about the comfort of the environment. It can be soft or bright, warm or cool. Accent lighting directs additional light and draws attention to selected objects and surfaces. Task lighting illuminates work areas for focused activities such as reading, paper work, food preparation, laundry, games/hobbies, and home office work. At this stage of the planning process, you also want to assign the proper amount of light to an area and decide where to place it in order to avoid glare and unwanted reflections.
Fixtures and Controls
When it comes to selecting fixtures, there is more to it than appearance and style. Before you invest any money in fixtures, consider the output you are looking for and how you will control it. Light distribution, light source, energy efficiency, color appearance and color rendering are all factors that impact fixture selection. A floodlight, a recessed can light, and a shaded incandescent table lamp throw totally different light, so take the time to look at color, output, and distribution. You may also want to weigh the maintenance and up-front installation costs of the fixtures you select. Non standard lamps, the design professionals term for bulbs, can be costly, as can installation and operating costs. Individual and automatic controls are available and can extend the lamp life of your fixtures. Controls are also used to highlight tasks, create a different mood, and give versatility to the overall lighting scheme.
