Building energy design is currently going through a period of major changes. One key factor of this is the adoption of net-zero energy as a long term goal for new buildings in most developed countries. To achieve this goal a lot of research is needed to accumulate knowledge and to utilize it in practical applications. In this book, accomplished international experts present advanced modeling techniques as well as in-depth case studies in order to aid designers in optimally using simulation tools for net-zero energy building design. The strategies and technologies discussed in this book are, however, also applicable for the design of energy-plus buildings. This book was facilitated by International Energy Agency’s Solar Heating and Cooling (SHC) Programs and the Energy in Buildings and Communities (EBC) Programs through the joint SHC Task 40/EBC Annex 52: Towards Net Zero Energy Solar Buildings R&D collaboration.After presenting the fundamental concepts, design strategies, and technologies required to achieve net-zero energy in buildings, the book discusses different design processes and tools to support the design of net-zero energy buildings (NZEBs). A substantial chapter reports on four diverse NZEBs that have been operating for at least two years. These case studies are extremely high quality because they all have high resolution measured data and the authors were intimately involved in all of them from conception to operating. By comparing the projections made using the respective design tools with the actual performance data, successful (and unsuccessful) design techniques and processes, design and simulation tools, and technologies are identified.
- One of these days, mankind will no longer rely on fossil fuels for energy. If you are interested in saving the environment and want to save on your energy bills, you should consider investing in a solar energy system. This piece will give you helpful advice.Solar energy through the use of solar panels can last up to 30 years. It is a long-lived use of energy and requires very little maintenance on your part. Since there are no movable parts, solar-energy panels don’t break or need repair. This can provide years of electricity bill savings.There are two types of solar panel. Mono-crystalline panels are pricier than poly-crystalline panels, but they’re more efficient. You should purchase the best possible product your budget can allow when it comes to solar power systems.If your roof cannot to support the weight of photo-voltaic solar panels, you can save a lot of money by investing in thin film solar panels. These panels are very light and flexible, which makes the installation much easier and affordable. Their higher price is also justified by their efficiency.Keep the trees around your solar energy panels trimmed. Shade from trees can limit the sun’s rays that are hitting your panels, thereby causing your panels to work less effectively. In order to avoid this problem, make sure to trim back leaves and branches regularly. This is easy to do, and it is cost effective too.Your home or business should receive at least five hours of direct sunlight per day to get the most from solar energy. Obviously more sun is better when it comes to solar panels, however if you get less than this solar energy can still be a viable option. If you are in an area where energy bills are sky high, solar might still save you money even if you don’t have the optimal sun exposure.For the best results, place your solar panels in a location that gets plenty of sunlight. Avoid placing solar panels near trees or tall buildings because they can create shadows on the solar panels which can result in poor energy consumption. Additionally, placing your solar panels in a Southwest location will result in greater energy absorption.In future years, energy production ought to be cheaper and less damaging to the Earth. Are you waiting for solar become standardized? Why not explore the options now? You will be amazed by the amount of money and energy you will save.
- People need to start relying on oil and other fossil fuels for energy. Solar power is a major component in the green revolution, and you can become a part of it. The piece that follows offers lots of useful tips and ideas.When it comes to solar energy, the sky is truly the limit, so learn about your options before you buy. How much space are you allowed, by local law, to fill with solar equipment? Can you sell excess energy back to the grid? What sort of regulations are in place?If you own a pool, consider using a solar water heating system to keep it warm in the cooler months. Solar heating is much less expensive than electric or even gas heating, and it is relatively easy to install. In the first year alone, you can save about thirty percent over the cost of heating your swimming pool with electricity.Get quotes from several contractors before signing any solar energy installation company. Just as with any other construction product, it pays to shop around before you commit to a particular company. Check out their reviews online and their standing with the Better Business Bureau. A little research ahead of time can save you a big headache later.Although the initial cost of solar panels can be quite expensive, you need to think in terms of future savings. Once your initial investment is paid off, you will never have to be dependent on another energy company again. This is because you will get all the energy you need from the sun.Take the time to compare different types of solar panels before you invest in a green energy system. There are different technologies and brands to compare and it is true that the most expensive panels are often the most efficient ones. Talk with vendors and professionals to learn more about solar panels.Solar panels are not very easy to install, so you should hire a professional to get the job done. While you will save a bit of money by trying to do it in your own, you do not want things to be less than perfect. Also, you will most likely end up paying someone to come out and fix the mess you made.Improvement is coming when it comes to environmentally-sound energy sources. There’s no reason to wait until everyone else has solar energy. Research the options now to see how much you could save and how you can reduce your own carbon footprint.
