Q: What is Home Energy Score?
A: The Home Energy Score is similar to a vehicle's miles-per-gallon rating. It helps homeowners and homebuyers understand how much energy a home is expected to use and provides suggestions for improving its energy efficiency. It also allows homeowners to compare the energy performance of their homes to other homes nationwide. The Home Energy Score includes: 1) the Score itself, 2) facts about the home including data collected and energy use breakdown, and 3) recommendations to improve the Score and the energy efficiency of the home. A score of 10 indicates that the home has excellent energy performance. A score of 1 indicates the home needs extensive energy improvements.

Q: What is ENERGY STAR®?
A: ENERGY STAR® is a joint program of the Environmental Protection Agency (EPA) and the Department of Energy (DOE). Its goal is to help consumers, businesses, and industry save money and protect the environment through the adoption of energy efficient products and practices. The ENERGY STAR label identifies top performing, cost-effective products, homes, and buildings. Since inception, ENERGY STAR has shown impressive results: in 2010 Americans saved enough energy to avoid greenhouse gas emissions equivalent to those from 33 million cars, while saving nearly $18 billion on utility bills.

A: Energy efficiency is a low cost way to save money and reduce pollution. Our homes, offices, schools, hospitals, restaurants, and stores consume a lot of energy and money. We spend millions of dollars each year to power our homes and commercial buildings; and much of this energy and money is wasted.

Q: What is a carbon inventory?
A: The prime objective of a carbon inventory is to provide an overall picture of an activity using a physical indicator – greenhouse gas emissions – instead of an economic indicator. In practice, a carbon inventory is a broad survey of the greenhouse gas emissions linked to a given activity, commercial or otherwise. This inventory encompasses all the processes that are necessary for the functioning of the activity, whether they take place within the company or outside of the legally defined corporate entity.

Q: What are the goals of a carbon inventory?
A: A carbon inventory is a decision-making tool, designed to: -establish priority measures to reduce your GHG emissions. -identify levers that will lower costs. -spur thinking about new growth drivers and innovation. -limit the vulnerability of your activity to fluctuations in fossil energy prices. -enrich your extra-financial reporting, and give you a new performance indicator.

Q: What about your dependence in terms of water supply?
A: When tackling climate issues the question of water resources inevitably arises. -Climate change modifies and will continue to modify the water cycle. -Water and energy are closely interrelated: electricity is needed to produce and distribute drinking water, and water is need to generate electricity. -The “water” question, like the “carbon” question, has an upstream dimension – resource availability – and a downstream dimension – pollution.
