The City of Nashua measures the energy used to heat and power our schools and municipal buildings. We do this to learn where we’ve been successful at lowering our energy consumption and where we should focus our efforts in the future. Energy-efficient buildings is a high impact strategy to reduce the City's total greenhouse gas emissions. The government’s effort to reduce energy sets an example for the community.

Municipal Energy Use

Our City Buildings

Municipal building energy consumption measures all of the energy used to heat, cool, and light the buildings owned and operated by the City government.

Energy from different sources is measured in different ways – electricity is measured in kWh, natural gas in therms, oil in gallons. We can convert these different measures into a common measure- million British Thermal Units (MMBTU) -to better understand and compare total energy use.

What are Lighting Our Streets?

Nashua completed an LED (light emitting diode) streetlight conversion. LED lights use up to 85% less than their traditional streetlight counterparts. This is one example of an City initiative to reduce energy use.

How do they work?

School Energy Use

Powering Education

This bar chart shows the total energy (MMBTU) our school buildings used by fuel type (natural gas for heating and electricity). In 2016 we used 9% less natural gas and 7% less electricity than we did in 2010. Five of our schools had interior and exterior lighting upgrades as well as other efficiency upgrades which helped made these reductions possible. We are looking to put upgrades in other schools soon.

Green Buildings

What are Green Buildings?

Buildings built to green standards use less energy for heating, cooling, and lighting and improve indoor air quality and comfort for the people in the building. A Livable Nashua will encourage new developments as well as major upgrade projects to follow green building standards.

There are different standards and levels for “green” buildings. This metric looks at the total for all types of green buildings including EnergyStar and the US Green Building Council’s Leadership in Energy and Environmental Design (LEED).

Certified Green Buildings

The total number of green buildings from both the LEED and Energy Star programs has increased over the years.
