Overall Strategy for Andover:

The Andover Energy Team’s prior grant project included retro-commissioning, which identified energy projects, and taught us how to evaluate our system efficiency. The lessons learned from this exercise empowered us to become more proactive with our approach. With eyes open the volume of work that could be done was overwhelming, so we strategized about how to move forward, improving efficiencies, dig deeper into what is possible, while not leaving pieces of our portfolio behind.

Our plan focuses on three major strategies:

1. Identify Andover High School, our largest building energy user, as our Flagship for energy efficiency projects. At this school we are digging deeper. We are working with an AHS student energy group, the Nega Watt Spotters(NeWaS) to analyze building energy usage, map zones, and our citizen Energy Team member is leading a class once a week to do this work. This grant will fund ghost plug load controls that the students will study and implement. It will also fund air sealing to improve the building envelope. Further embracing LED lighting and controls, we have included a hallway retrofit for lighting with occupancy dimming controls.

2. Build efficiencies into or Water system, our largest overall departmental energy user. We are currently funding VFD’s at our Fishbrook Pump Station and rebuilding the West Service pumps. Included in this grant application is the last of the three major pumping locations in Andover, the Bancroft pumps and motors.

3. Set standards town-wide for Andover energy. In addition to the Green Community standards we work to adhere to, we are creating a White Paper for Andover building operations to specify minimum standard on construction, purchases, operation and retrofits. For example, we implemented an Energy Star policy whereby all office refrigerators purchased must be Energy Star certified. We are retrofitting all shops and bays with LED overheads, linked heating systems to bay door position and added these to our standards. In keeping with this strategy, we have submitted interior hallway lighting upgrades identical to the AHS project at two additional schools: West Middle and West Elementary. Identical to the hallway lighting proposed at Andover High School, these lights have occupancy and dimming capability as will be the new hallway standard throughout the Town.

On the following pages the individual narratives for each of these projects will be described in more detail and according to the grant instructions.

Andover High School Energy Consumption (MMBTU): Building Electricity Natural Gas Total Andover High School 7,194 11,339 18,533

Purpose: This project was crafted by the Energy Team to dig deeper into the energy challenges of this site, to engage the building occupants, promote energy education and identify AHS as our Flagship location by digging deeper into energy use, including identifying “ghost loads” and air leaks, to locate where energy is being wasted. Through the retro-commissioning process we discovered a significant use of electricity overnight. Improved control on hallway and exterior lighting and control of plug loads were chosen as targets to reduce overnight usage. A building envelope audit pointed to air seal cracks between the outside walls and ceiling of the building, and the need for additional weather stripping to reduce heat loss/air infiltration. Students and our citizen volunteer are working through a science club to map zones, identify pneumatic controls, leaks, ghost loads, and are analyzing data from the energy management system. We will include signage to highlight recent energy improvements and the work of the students at the end of the school year, with media coverage and a poster presentation by the NeWaS Club.

Project components include:  Air Sealing and Weather Stripping  Plug Load Energy Management  Interior Hallway LED Retrofit with Controls  Exterior LED Retrofit  Signage and Outreach

Benefits: These projects will result in electricity and natural gas savings, smarter lighting, and possibly the extended life of equipment powered off. In addition, it will provide hands on educational opportunity for Andover High School students, connection between Andover residents and staff, and a greater sense of ownership of the facility by its residents. We also will use this opportunity and AHS as a Flagship to promote new technologies and controls. We are planning a signage campaign and poster presentation to showcase the energy improvements at AHS and educate officials and the community.

Timeline: Work will begin as soon as we are granted a notice to proceed. Based on an expected notice date of September 1, project component timelines are as follows:

Project components timeline:  Air Sealing and Weather Stripping October 2015  Plug Load Energy Management September 2015 – May 2016  Interior Hallway LED Retrofit with Controls January 2016  Exterior LED Retrofit November 2015  Signage and Outreach May-June 2016

Support of Andover’s five year Energy Reduction Plan: Andover Energy Team’s plan is to set a standard – Raising the Bar – for energy related purchase, retrofits, and construction. Retro-commissioning is an excellent tool, but is often not fluid. In order to maintain the level of control needed we need to investigate proven technology, implement, and evaluate, and move toward making successful technologies system-wide. For example, we have plans

Andover Energy Team 5 Year Goals: 1. Establish Andover High School as our Flagship, engaging students and teachers, and digging deeper to identify savings. 2. Improve efficiency in our Water/Sewer System. 3. Set standards for Andover energy and craft system improvements across the board. 4. Educate stakeholders and advertise our success. 5. Improve ongoing performance by tracking energy use, sub- metering, building automation and analytics to identify future energy projects and quantify the effects of those completed.

Grant Funding Request Justification: Funding in a constrained budget in what is largely a bedroom community can be difficult. Rising utility costs can ironically hurt energy project funding, even while these rising costs point to more need. Funding through this grant program will allow us to keep moving forward as we refocus on the next five years.

Permits Required and Status: No building permit is required for air sealing, weather stripping or plug load management. Electrical permit are required for the lighting retrofits. No permits have been submitted.

Other Approvals Required: Signage will only require the permission of the School Committee and/or superintendent who support this project.

Education and Outreach Opportunities and Plan to Accomplish Them: We are planning a signage campaign and poster presentation to showcase the energy improvements at AHS and educate officials and the community. The student science club is already established and is working on evaluating energy, with a sponsor teacher and citizen volunteer and staff member from the Andover Energy Team. Student poster presentations are customary at Andover High School, and the Andover Energy Team took part last year through the Environmental Sustainability class intern program, which we plan to participate in each year. Since poster presentations are a useful college skill, Andover High School supports these efforts. Staff and elected officials regularly attend poster presentations by AHS students.

Total Project Budget: 160,347.00

Other Sources of Funding: Other sources of funding include $23,592 Andover town funding through energy conservation budget, and $46,250 in utility incentives from National Grid and Columbia Gas.

Administrative Costs Required: None.

Summary of Measures Proposed in this Project: Air Sealing and Weather Stripping: As part of a building envelope air sealing project, two measures were identified, sealing the wall to roof area around the perimeter of the building, and weather stripping other building openings. As part of this project we included both in our project description, even thought the Town of Andover will fully fund the weather stripping portion. Only the air sealing qualified for gas incentive, so we put forward that portion to be funded through the grant. Building envelope is often disregarded because it may not qualify for utility incentives, however, the Andover Energy Team feels strongly that these projects need to move forward. Plug Load Energy Management: 120 plug load controllers with software will be purchased and over 500 locations in Andover High School will be studied for the best location of these units. Students will learn about energy use and energy management scheduling. Interior Hallway LED Retrofit with Controls: 205 T8 fixtures will be replaced with smart LED lighting in the Hallways at Andover High School. Exterior LED Retrofit: 27 metal halide wallpacks and floods around the exterior of Andover High School will be replaced with LEDs. Signage and Outreach: Andover Energy will fund this measure. It is included here in the project to show our excitement and commitment to our Flagship program, and to ensure that the outreach and signage are measurable goals included in this program. At the end of large projects we have completed before, we did not spend enough time advertising our achievements and engaging the community. With this plan and future projects we hope to do better.
