Your degree day website is an extremely valuable resource for the energy industry. I have been looking for this type of data for a very long time. I congratulate you for organizing a huge amount of information into a user-friendly interface that nearly everyone should be able to maneuver.

I will introduce your website to my students when we are studying the correlation between heating degree days and space heating consumption, comparing an efficient envelope with an inefficient envelope, and comparing HDD at different temperature bases.

Please keep up the good work - it's very valuable!

I find the BizEE Degree Day web site very useful for our property management activities.

We prefer to obtain HDD/CDD data that coincides with our utility billing periods. The BizEE site has enough flexibility that I can obtain the data needed by pulling one or two reports at most to cover the dates needed.

I'm a green energy consultant, and Degree Days.net helped me understand how to predict my future energy consumption.

I live in Catania (Italy) and it's surprising to see how easily I can manage my energy bills using my local weather station data.

I recommend this tool, it worked to lower my air conditioning energy consumption needs.

Thank you for a very useful site. I live well outside of Boston and our heating seasons are 20-25% colder. Until I found your site, I did not have a reliable source of degree data for my area. I can now better understand the effects of energy efficiency improvements I might make by taking the variability of the winters out of the equations.

Bob Marchetti

I am in the HVAC & energy management business. We track utility usage (gas & electric) against HDD & CDD.

The NOAA site is cumbersome in that we cannot sort by just our zip and get the data... It takes some time to filter thru the data (and a lot of wasted printing). It is nice that your results go right into a spreadsheet.

Your explanation of HDD and CDD is great. Your explanation of its usefulness is VERY informative.

Thanks and keep up the good work!!

I love it. I'm in the process of developing training for building operators for buildings that are on Toronto's Deep Lake Water Cooling (DLWC) central cooling system, and am introducing them to monitoring & targeting. Having this source of CDD data is really helpful, in part to show the impact of base temperature. I'll certainly reference your site in the training as well as with colleagues who are in the same line of work.

Doug Tripp

I like that you can search a local weather station and download the data in excel so that it's easy to manipulate. Last year when I tried to analyze my heating bill it was a big hassle. I could only find generalized numbers for the major wx stations. Thanks.

Roger LeCompte
Old Saybrook, Connecticut

The information that I downloaded was very helpful in estimating some natural gas billing that the utility has not issued for the past few months for one of our clients. I appreciated the easy maneuverability of your website and quick download.

I am in the market for a new HVAC system and have used degreedays.net extensively to help me understand the "tipping point" of hybrid systems (I am considering both geothermal and air-source heat pumps).

I have also shared the site with others who were trying to determine their savings from installing geothermal. Degreedays.net really helps to ensure a fair comparison across different years.

I use the BizEE degree days info monthly. I am responsible for operations and reporting of HVAC and fuel for a 400,000 sq. ft. facility here in east Tennessee with an annual budget of around $3,000,000.

This makes comparing energy usage between months and years much easier. Thanks for your information and availability.

Dave Samsel

I love your HDD website. I work at the Erie Housing Authority. The federal government, through HUD, funds our Public Housing program. Utility costs are something that we are required to track very closely. Your web site makes this a lot easier for me.

We are in the process of replacing 1,300 furnaces with new high-efficiency models. I am sure that in the next few years I will get many questions on our natural gas consumption. Your web site will definitely help.

Thanks for all of your work making this as quick and easy as possible.

I'm doing an MSc in Building Design at De Montfort University in the UK. Our assignment is on degree days and I've found your website a super resource and have told everyone on the course to check it out.

My analysis shows that you've done a very thorough job of calculating the degree days. Your results are excellent and your website is very informative and useful for real design work. Your explanations of degree days and their pitfalls and advantages are spot on.

Thanks heaps.

The Degree Days.net web site is extremely helpful... I use it to educate others, taking say 75 degrees for cooling, then using 76 degrees to see how it affects the cost. I've put together a spreadsheet where the Facility Managers can add up all their equipment load. Using the different temperature settings and average KWh cost it calculates the difference in operating costs.

I feel that this type of information is going to become more and more valuable as our nation continues to press forward with conservation and efficiency. In the utility industry we have seen a big push for cleaner and cheaper power but, without the data that you provide, it makes it difficult to judge the factors of weather and how they affect the overall demand for power.

Matthew Jones

We'd like to add our thanks too...

Our heartfelt thanks goes out to Weather Underground for making this site possible by giving us permission to use their huge database of temperature data to calculate our degree days from. Much obliged Weather Underground!

OK... But where can I get the degree day data?

If you've stumbled across this page by accident, we appreciate that you're probably less interested in reading a selection of quotes than you are in downloading some degree day data. No problem at all:
