What is Energy Use Intensity?*

…And how “green” are the proposed Lincoln School project concepts?

Find out at the School Building Committee (SBC) Meeting on Wednesday, March 7th @ 7:00pm in the Hartwell Multipurpose Room

Bill Maclay, Founder of Maclay Architects, and Martine Dion, Prinicipal Architect and Director of Sustainable Design, SMMA, will be on hand to present the results of Maclay Architects’ energy performance analysis of each of the 5 project concepts presented at the January 23rd Community Workshops:

  1. Repair-Only
  2. Renovation of Current Building
  3. Renovation + Some Additions (concept A1.1)
  4. Comprehensive Renovation, Current Footprint (concept A3.4)
  5. Mostly New, Compact Footprint (concept B6)

The analysis includes:

  • options for differing levels of building envelope energy performance
  • mechanical systems optimization
  • construction cost estimates
  • energy modeling for both annual consumption and building enclosure related energy usage
  • 20-year capital and operating costs and cash flow estimates
  • definitions of energy conservation levels and associated Energy Use Intensity (a.k.a. Energy Utilization Index)

*Energy Use Intensity = The amount of energy (kBtu) consumed per square foot of a building.  It is calculated by dividing the total amount of energy consumed in 1 year by the number of square feet in the building.


Martine Dion, AIA, LEED AP BD+C, is a Principal and Director of Sustainable Design at SMMA with 25 years of experience. She provides sustainable design and LEED-consulting services to the full spectrum of SMMA’s clients. Martine has been in charge of the implementation and coordination of sustainable design practices for the firm for the past 18 years, and has largely contributed to its consolidation across the firm’s A&E disciplines. Regarded as an expert in her field, she is a founding director of the U.S. Green Building Council’s Massachusetts Chapter, and has contributed to the AIA’s National Committee on the Environment, to Massachusetts’
Roundtable Action Plan for Green Buildings and Former Massachusetts Governor Deval Patrick’s Zero Net Energy Task Force, the U.S. Department of Energy’s Zero Net Energy Task Force. Martine sits on the recent DOER ZNE Advisory Council and is a Board Director of the NESEA Board of Directors.
As Director of Sustainable Design, Mrs. Dion identifies opportunities in each of SMMA’s projects to advance clients’ goals for energy efficiency and conservation of resources. Initiatives to be explored include siting of the building, solar orientation and shading, design of operating systems and enclosure systems, materials selections, and construction methods. She leads the Energy Efficiency Group at the firm, managing consulting contracts with National Grid and Northeast Utilities, as well as Post-Occupancy evaluation initiatives. Mrs. Dion is trained under the Living Building Challenge certifications program.
