·The Future·

Carbon Neutral Living

Onsite Renewable Energy Generation
Upgraded Building Systems
Decarbonized Properties

RENU is leading the transition to a carbon neutral built environment.

Carbon neutral real estate

We deliver decarbonized energy retrofits to existing real estate assets.

Climate action starts with improving energy performance within the built environment.

Buildings consume

40% of energy produced

70% of electricity produced in the U.S.

They account for nearly

40% of annual global greenhouse gas (GHG) emissions

12% of direct GHG emissions in the U.S.


Operational Value

State and local governments are committing to meeting greenhouse gas reduction targets, while property owners confront additional legislative and financial burdens associated with greater environmental responsibility. The requirements are still evolving, and RENU allows owners and operators to stay ahead of the environmental regulations.

RENU’s comprehensive approach provides a carbon neutral transition for the built environment.

How It Works

We decarbonize the built environment by lowering energy demand through comprehensive retrofits, infrastructure upgrades, electrification, and on-site/off-site renewable power generation.

Property Assessment & Energy Analysis

We perform comprehensive analyses on existing properties to determine the best combination of energy performance technologies. We can then provide a customized roadmap to achieving specified carbon reduction and financial goals.

Design Study & Implementation

Our team designs onsite energy systems best suited for carbon neutrality. We consider the application of battery storage capacity, solar, and our proprietary geothermal model (GeoGrid™). If necessary, additional energy needs can be generated with local, off-site renewables. We create the optimal financial structure and cooperative relationships between the property owner, the utility, and state and local governments.

Energy Management & Maintenance

Once the new equipment and energy infrastructure is fully installed, our Energy Management system provides continuous monitoring on a per household/ business basis. Real-time data yields energy insights and underscores new opportunities for ongoing optimization.

RENU In Action

Over the next 30 years, the current RENU portfolio is projected to save

of CO2 from our atmosphere

Our projects will save the energy equivalent of:

Carbon sequestered by 270,000 acres of forest

Greenhouse gas emissions from 554,000,000 passenger vehicles’ miles

CO2 emissions from 243,000,000 pounds of coal

South Winds

South Winds

South Winds Apartment Community provides an ideal foundation for RENU’s Carbon Neutral Energy Efficiency retrofit program.

3,441,000 kWh

permanently saved through energy efficiency

1,427,000 kWh

produced through on-site renewable energy

3,803 tons

of CO2 avoided per year
South Winds is a 27 building, 404-unit garden-style multi-family complex in Fall River, MA. The complex features a mix of 1, 2, and 3-bedroom units arranged in 3 story buildings across a 27-acre property. Originally completed in 1972, the all-electric property features many of the original building systems.

Through the RENU process, South Winds is expected to avoid 3,803 tons of CO2 each year. To date, RENU improvements to the property’s building envelope include upgraded doors, windows, LED lighting, insulation and weatherization. Going forward, plans call for a full retrofit of existing HVAC with advanced cold-climate air source heat pumps to dramatically reduce energy demand and improve energy resiliency.

In order to meet the remaining energy consumption of South Winds using a renewable source, RENU is in the process of installing roughly 1.37 MW (DC) of rooftop solar PV.

Following the construction of the property’s new energy infrastructure, RENU will manage, maintain and monitor these systems to maximize energy efficiency and environmental health through our integrated energy management and monitoring system.

300 Baker

300 Baker

RENU’s flagship project in the commercial office market.

1,604,000 kWh

permanently saved through energy efficiency

1,318,000 kWh

produced through on-site renewable energy

2,283 tons

of CO2 avoided per year

300 Baker is a 3 story, 417,000 sq. ft. Class-A commercial office building constructed in 1952 and located in Concord, MA. The building has over a dozen tenants with a range of business types and layouts. This property has undergone multiple additions over the decades, and while there have been some major systems upgrades, many of the systems are over 40 years old. 

Through the RENU process, 300 Baker is expected to avoid 2,283 tons of COeach year. RENU improvements to the property’s building envelope include window upgrades, envelope weatherization/sealing, and LED lighting upgrades. The RENU scope also includes full retrofit of the HVAC system, thus incorporating RENU’s GeoGrid, a Geothermal HVAC system. Along with the GeoGrid, other HVAC upgrades include a perimeter heating system, heat recovery system, dedicated outdoor air system, and air handler/cooling system. 

With the aim of maximizing COsavings at 300 Baker, RENU installed 900 kW (DC) of rooftop and canopy solar PV. This will help to convert the property into a sustainable real estate asset with low energy demand and high energy resiliency. 

Following the construction of the property’s new energy infrastructure, RENU will manage, maintain, and monitor these systems to maximize energy efficiency and environmental health through our integrated energy management and monitoring system.
