Installing outdoor night-time lights can really make a difference. I live on a large estate and there are no street lights, so we have to use extra night-time lights dotted along the paths that lead up to our front door. Our front door has also got a big tree planted in the centre of it, so we have trees lined up on all sides of the house blocking the view of each other. Without these night-time lights, it would be impossible for any of us to see the tree or our guests walking towards us. Having these lights in the correct position has also meant that we don’t get lost in the night – we know exactly where we’re at all times. This makes our house look less like a home and more like a holiday home. Visit BetterLumen for more information.
Night lights come in many shapes and sizes. They can be made from a wide variety of materials, including wires, plastic, fibre, plastic, clear plastic, fibre optic cable and even glass. Each one has its advantages and disadvantages. However, there is one thing which is very common across all kinds of these lights: they all utilise statistical analysis to achieve their illuminate output.
A statistical analysis is an economic model that uses data to simulate how various economic variables will change if a variable is changed. It uses the Google Surveys API (which is essentially Google’s questionnaire tool) to collect respondents’ answers to questions about energy consumption, night-time lighting and general lighting conditions in their property. Once the model is complete, it then produces a number of output variables that each respondent can choose to represent them, depending upon how closely they match the real outcomes from the survey. This process is quite natural for many different types of economic models: it’s called a Monte Carlo simulation. If you want to understand exactly how the output variables are estimated, all you need to do is ask Google scholar what it’s called.
The Google Surveys’ website explains it quite clearly, and it explains why this kind of research is important: “It lets us know what kinds of products and activities people are willing to pay for, as well as what kinds of things are more likely to improve their well-being. This information allows us to take action in areas where we might not have otherwise had a clue,” says Zivkovic. The beauty of this research is that it’s all done on data that’s been collected in prior studies. The questions don’t change much, for example the quantity of energy used by a household, or the average number of hours per year for a family spends in front of a TV. All the factors that make up these questions are based on prior studies. These prior studies were then studied to check the robustness of the model.
This kind of research is done before consumers actually buy any products, so that researchers can study the correlations between attributes that influence human behaviour and the quality of LED bulbs and other lighting technologies used in a certain area. They can see which areas of a neighborhood are more well lit, and which are unlit. They can see the correlation between pollutants outside a home, and the quality of air inside the house. In other words, they can study real-world attributes that affect prices and utility bills, and study how people respond to them in the real world.
The Google team has also worked on a number of other projects related to energy consumption, and the relationship between neighborhood demographics and energy consumption. For instance, they studied the correlations between geographic features and nighttime energy consumption, such as co2 ratios and distance to light. By taking into consideration the effects of these relationships on nighttime brightness, they were able to better determine how to filter street lights with low intensity gDP lasers, and improve energy efficiency at the same time. By combining these different geographic-based measurements with co2 measurements from individuals, the Google team was able to map the house interior lighting environment, and create maps that inform users of the correlation between characteristics and prices. The mapping helps people make informed decisions about how to optimize their energy use.
