 ===== Special Loads =====
 ===== Space Function & System =====
+**System-Summary**
+"In the space function and system section, you will have an opportunity to clearly and accurately described the different areas in your facility.  Let's take a small industrial building as an example.  This particular building has a front door where customers enter into a reception area followed by a conference room, individual offices, and open cubicle area, a kitchen, two bathrooms, and a warehouse.  In this example, seven different spaces should be described.  While most areas are singular, the individual offices in the two bathrooms have multiples of the same design.  While listing every single office and at individual bathrooms will give you the best results, it is typically not necessary for purposes of ASHRAE level 1 report.  You can therefore create a space name of ""private offices"" and another one called ""restrooms"".  If you're building has multiple floors you may want to repeat this process for each floor unless these floors are virtually identical to each other.
+Let's look at that as another example.  A 10 story building has multiple tenants, but one tenant has four floors that were designed exactly the same.  You could then create a space name like "7th-10th floor office suite".
+This is typically acceptable for ASHRAE level 1 standards. If also typically acceptable is listing all your restaurants together as they are frequently designed the same.
+For each space that you create, there are four types of data that are requested.  The first tab is the function of the area.  The functions are listed utilizing the ASHRAE defined types of functions.
+The second tab is lighting.  This is where you will describe the type of lighting, controls, and the intensity of the light and also you can record how bright the lights are (foot candles) among other data. You can also upload a photo of the lights or perhaps of the ceiling in general. Although photos are not required for this section, it does add value to your report.
+The third tab is HVAC.  This is where you can describe the type of air conditioning that services the space and input details like temperature setpoint, type of system, capacity, problems, etc..  You can also upload a photo of the air-conditioning or perhaps of the thermostat.
+The last tab is for an image of the space.  Frequently it is of great value to include a photo of the space you're describing in order to make it easily recognizable to someone who is reading the report."
+**Space-Name**
+Create a space name for your spaces like, "Suite 100" or "Restrooms".  If you're building has multiple floors you may want to repeat this process for each floor like "5th Floor Restrooms" unless all of these rooms on all floors are virtually identical to each other.
+Let's look at that as another example.  A 10 story building has multiple tenants, but one tenant has four floors that were designed exactly the same.  You could then create a space name like "7th-10th floor office suite".
+**Location**
+Adequately describe the location of this space like, "3rd floor North Side.
+==== Functions ====
+**Function-Type**
+Click in the box to pop up a menu of the ASHRAE defined function types and select the type most suitable for your space.
+**Conditioned-Area**
+Please input the amount of square footage associated with the space.
+**Space-Usage**
+Please input how many hours this space is utilized.  Format your input similar to this; "68 hours/week", or "80 hours/monthly", or "160 hours January and February only".
+==== Lighting ====
+**Lighting-Type**
+Please select the most predominant type of lighting technology used.
+**Typical-W-ft2**
+The ASHRAE level 1 recommendation is to list the lighting power intensity.  This is referenced as watts per square foot.  A simple way to do this is to count the number of light fixtures in a certain size area and then calculate the resulting watts per square foot.  For instance in a 40' x 50' room you have 2000 ft.² if you have 36 fixtures that each have two 32 W bulbs installed with a balance that consumes 6 W, then your lighting system as a power of 2520 W. when you divide this wattage by the 2000 ft.² in the room, you get a lighting power density of 1.26 W per square foot.  This would be your answer.
+**Design-of-Controls**
+Most common types of lighting controls are switches, occupancy sensors/motion sensors, timers, and photocells.  Although you may have more than one type of lighting control in the space, please select the one that operates the majority of the lighting.
+**Foot-candles**
+"Light level meters can be purchased for low cost, so it makes sense to get one for performing energy audits. It is best to take readings at night to prevent infiltration of sunlight from making it appear that a facility may have too much lighting. Readings should be taken at the working surface. The Illuminating Engineering Society publishes illuminance recommendations in table form. These tables cover both generic tasks (reading, writing etc), and 100's of very specific tasks and activities (such as drafting, parking, milking cows, blowing glass and baking bread).
+All tasks fall into 1 of 9 illuminance categories, covering from 20 to 20,000 lux, (2 to 2000 foot-candles). The categories are known as A - I, and each provide a range of 3 illuminance values (low, mid and high). See Table 1. Although only a lighting designer can make recommendations, we want to give you the following as possible examples; Category A might be a sidewalk leading to a building or parking lot, B might be a corridor, C might be restrooms, D might be desks where computers are used, E might be drafting or drawing desks, F and G might be manufacturing or assembly, H and I might be fine assembly or surgery.
+A-C for illuminances over a large area (i.e. lobby space)
+D-F for localized tasks
+G-I for extremely difficult visual tasks

+==== HVAC ====
 ===== Unoccupied Setback =====
+Unoccupied setback describes the function of changing temperature and humidity setpoints as well as pumping pressure and circulation setpoints to a more energy-efficient level when the building is unoccupied.  You can add as many types of systems as you need to and then use the drop-down menu to select the type of setback control.
