The first thing you have to do is figure out what the actual lighting is used to judge.

From the question you asked, you already know to measure in terms of square meters. However, it is wrong to use "how many watts per square meter", it should be "how many lumens per square meter", that is, "illuminance". You think, the light efficiency of different lamps is different, ordinary fluorescent lamps are more than 50 lumens per watt, T8 tri-color fluorescent lamps are more than 70 lumens per watt, and T5 tri-color fluorescent lamps are more than 80 lumens per watt.

If the same 40 watts, the ordinary one is more than 2,000 lumens, and the T5 trichromatic one is more than 3,200 lumens.

Lumens is brightness, and the brightness of the illuminated environment can be expressed by "how many lumens per square meter" of illumination.

Calculating illuminance is not a simple matter, in addition to looking at the area of the room, but also to see how high the lamp hangs (the height should be reasonable), but also to see the degree of reflection of the wall, etc.

Generally speaking, supermarkets use 6500k, illumination 250 to 300 lumens square meters. If the lifting height is 3 meters, the amount of lumens required can be calculated according to 500 to 600 lumens square meters; The number of lamps should also consider the uniformity of light.

To add, the so-called "hanging height of 3 meters" refers to the distance from the lamp to the object to be illuminated. I designed for the factory, and the distance from the lamp to the workbench was the lifting distance. Supermarkets are different, today I specially inspected the size of the supermarket, the objects are stacked high, the size of the supermarket stack height is different, the shelf interval is not the same.

According to the estimation of the lamp height 1 meter from the highest shelf, with T5 and T8 energy-saving lamps, 3-4 watts per square meter; With general energy-saving lamps, 5-6 watts per square meter. It's just an estimate, but it's pretty much the same.

There are generally two ways to deal with underground parking spaces, one is that the developer sells the parking space, and the other is to rent the parking space. The exact method used depends on the developer's ownership of the underground parking space.

In the first case, the developer alone takes ownership of the underground parking space. In this case, the floor area of the underground garage is not apportioned at the time of sale, and the developer can sell the car into the Mori Oak Sale. The developer transfers the ownership of the parking space to the owner, and the owner has the right to occupy, use, earn, and dispose of the parking space after obtaining the ownership of the parking space.

If the developer only sells the underground parking space, if the owner does not purchase the underground parking space, he cannot park the car in the underground garage.

In the second case, when the house is not fully sold, the developer and the owner of the community jointly have the ownership of the underground parking space. In this case, the developer apportioned the construction area of the underground garage at the time of sale, and the developer is also one of the owners, and the ownership of the underground parking space is shared by all the owners, and the developer and the owners of the community should jointly decide the possession, use, income, and disposal of the underground parking space.

In the third case, after the house is fully sold, the developer does not have ownership of the underground parking space. At this time, the developer is not the owner, and the ownership of the underground parking space is shared by all the owners. The developer does not have the right to decide how the underground parking spaces will be used.

If the owner's car is stolen or damaged in the parking lot of the community, will the property management company be liable?

The property management company has the obligation to manage the safety of the community. The obligation of this safety management includes the management obligation of fire prevention and disaster prevention, entry and exit personnel, and public order in the community, which also includes the management obligation of the parked vehicles in the community.

To put it simply, LED lights should be bright and save electricity, fluorescent lamps are ordinary tube electricity is not lit, 18 watt LED lamps are equivalent to 40 watt fluorescent lamps.

Yixing LED fluorescent lamp 18W is equivalent to ordinary fluorescent lamp 40W

Yes, how many floors are built? Functional requirements for each floor: How many bedrooms, living room, dining room, kitchen and bathroom do you want on each floor?

The calculation formula is: power (w) * time (h) 1000

A 1000W fluorescent lamp consumes 1 degree of power after 1 hour of use.

A 36-watt fluorescent lamp uses electricity for an hour, 36*1 1000 = degrees.

Fluorescent lamps are fluorescent lamps, and traditional fluorescent lamps are low-pressure mercury lamps, which use low-pressure mercury vapor to release ultraviolet rays after being energized, so that phosphors emit visible light, so it belongs to low-pressure arc discharge light sources. 8 watts, 20 watts, 30 watts, 40 watts, etc., can be calculated according to kilowatt-hours of electricity. For example, a 20-watt fluorescent lamp consumes one degree of electricity for nearly 50 hours on average, and a 40-watt fluorescent lamp consumes one degree of electricity for nearly 25 hours.

The area of each parking space in the underground garage is calculated as 35 square meters, 10,000 35=, that is, 285 parking spaces can be set up in the 10,000 square meter garage.

Each parking space in the outdoor open-air parking lot is calculated according to 25 square meters, 10,000 25 = 400, that is, 400 parking spaces can be set up in the 10,000 square meter parking lot on the ground.

Non-motorized vehicles are generally calculated according to bicycles, when parked in the form of arrangement, the area is not the same, in most cases according to the double row on both sides, that is, each vehicle parking area square meter calculation, can also be estimated by square meters.

The channel area is included. For example, 10,000 square meters, 10,000 non-motorized parking spaces can be set up.

The length and width of each vehicle can be calculated on a per-basis basis.
