Building owners can save money by investing in energy efficiency improvements. But if they can’t afford the upfront costs of the upgrades, they continue to pay higher energy bills and are even less able to pay for energy efficiency improvements down the road.
On-bill financing (OBF) is one tool to help owners break out of this cycle. It provides an opportunity to invest in energy…Continue
Energy efficiency is a term given to the process of using energy that maximizes power saving without reducing service or utility. In a developing country like India, energy is the capital on which industries thrive. To fulfill industrial needs, a lot of energy is produced within the country as well as purchased from foreign lands. The result is a lot of expenditure and pollution. To make things worse, there is a lot of mismanagement of the grids that leads to considerable loss of…Continue

The major chunk of the electricity bills are covered by the primary long term appliances in the house including refrigerators, dishwashers and washing machine etc. These are those appliances that consume most of the energy and are used on a frequent basis. Refrigerators in particular are operated constantly apart from the time when the entire house goes for a vacation. In some cases the refrigerator still operates in absence in order to prevent the food from rotting. In the case of those…Continue

A new study from the National Institute of Standards and Technology (NIST) revealed that poor installation of air conditioning and heat pump units often leads to unsatisfactory energy performance. This research took three years to compile, with the help of surveys, field evidence, and various measurements for modeling. The most common installation errors included leaky ducts, improper refrigerant charge, oversizing of systems, and restricted…Continue
Sandeep and Carolyn Sood own several apartment buildings in Chicago, but the 55-unit building at 6731 S. Jeffery Boulevard is special. The building is one of the first in the country to receive the new ENERGY STAR® certification for multifamily buildings.
“For us, it’s an important designation. It shows people that want to live here that we care.…Continue
One of the most expensive aspects of being a homeowner, other than a mortgage, is money spent toward heating and cooling your home. It becomes a balancing act of sorts, trying to find that perfect comfort level in your home. As many homeowners know, finding that comfort level proves even more difficult with the more people living in your home.
As homeowners we look for every advantage to achieve this comfort level while at the same time trying to save money on our energy cost. This…Continue

It seems that our public schools are constantly in panic mode, looking for ways to save money and allocate limited resources. So it’s particularly exciting to tell you about a project where aerosealing just a single elementary school building is saving one school district about $45,000 a year. That’s a lot of…Continue

In July 2013, the State Board of Building Regulations and Standards (BBRS) voted to adopt the 2012 International Energy Conservation Code (2012 IECC) and ASHRAE 90.1-2010 with MA amendments as the new baseline energy code. The BBRS allowed for the new regulations to run concurrently with the current energy regulations until July 1, 2014. During that time, either set of energy regulations could be used when applying for…Continue

In case you haven't heard, last year RESNET created a task force to look at ways to improve the consistency of results among certified home energy raters (aka HERS raters). In mid-August, executive director Steve Baden sent an email about the latest developments in the process. He also attached a document titled…Continue

Mini-Split Heat Pumps are Quirky and Still Effective
The name "mini-splits" generally refers to heat pump systems with one outdoor unit and one or several smaller capacity air handlers. The efficiency of their operation comes via the inverter compressor and variable refrigerant…Continue
Liz Vogel replaced the windows and updated the heating system in her small multifamily building in the Logan Square neighborhood of Chicago. But she still noticed that parts of her home were not staying warm in winter. So she set out to solve the mystery of the missing heat. She saw icicles hanging from her roof, and that was a clue that pointed to where heat was escaping. The presence of these “ice dams” meant that Liz was paying to heat her roof and melt the snow instead of heating her…Continue

It is all ways great advice for small businesses to diversify, I know it pulled our company through a recession and is solely responsible for us coming up on our 20th year in business.

The Residential Energy Services Network (RESNET) announced its collaboration with the International Code Council last week in an effort to help home builders transition to the new 2015 International Energy Conservation Code (IECC). In the upcoming version of the residential building code, RESNET's HERS Index will be an optional compliance path — some people are saying that this compliance path represents the most significant change coming to 2015 IECC.
What is the…Continue
