This app is meant to provide homeowners with a ball park estimate of the upfront cost of a pv system. It will also
provide them with costs based off of what percentage they want to offset their electic usage, and taking into account federal tax incentives and current utility rates
Problem
There is a lot of information that goes into estimating the total cost of a pv system. It can be overwhelming for a homeowner to calculate this cost and for a solar installer to make that estimate will cost them money if in the end the homeowner decided that the economics is not worth it. A simple and easy to use calculator could better inform a homeowner if solar is right for them.
these are functions that stands for Create, Read, Update, Delete
There are seven verb + path combinations that are necessary in a basic Sinatra app in order to provide full CRUD functionality. List each of the seven combinations, and explain what each is for.
get '/resources' - this retrieves the resources
get '/resource/:id'- this retrieves the one resource
get '/resources/new - this retrieves a form or some format for add resource
post '/resources' - this creates the new resource
get '/resources/:id/update - this retrieves a form that allows a specific resource to be modified or edited

My topic is on the sciences of buildings, in particularly the envelop of the building and the physical forces acting on the air boundary of the house. The physical forces that I will talk about are `convective heat transfer` and `air pressure`. Both play a part in how air movement happens in a building and the associated energy losses.
Houses have to breath, meaning the moist, stale air inside the house needs to be exchanged with fresh outside air. The national standard for the natural air change rate per hour (NACH) is about 3. This roughly means that a house with a NACH of 3 exchanges 30 percent of the air volume of the house every hour (occupancy level will change this number). More than this is considered a waste or what is commonly called a “leaky” house. This is were we as energy auditors focus most of our attention when doing an audit on a home. The reason is because the air infiltration of a “leaky” house can lead to 30 percent of your energy bill. The other reason is because air sealing is the quic
