Andelman and Lelek Engineering

What Andelman and Lelek Engineering does

Andelman and Lelek Engineering (ALE) is a privately held engineering consulting firm founded in 1998 by Magda Lelek and Michael Andelman, headquartered in Norwood, Massachusetts. The firm specializes in building energy modeling, energy efficiency consulting, commissioning and retro-commissioning of building mechanical systems, and sustainable building development support. Its core technical competency is computational building energy modeling — used to influence new building design optimization, demonstrate cost-effectiveness of retrofits for existing facilities, support utility incentive program qualification, and enable certification under LEED, CHPS, Energy Star, and Green Communities frameworks. The firm has expanded its service line to include embodied carbon analysis, daylighting modeling, combined heat and power assessment, energy modeling training, and measurement and verification of building energy performance.

ALE serves institutional and commercial clients on a project-based consulting basis, with primary customer segments in K-12 schools, higher education institutions, state and municipal agencies, healthcare facilities, and commercial real estate and hospitality. The firm works both directly with building owners and as a sub-consultant to architectural and engineering firms. Its geographic focus is New England — principally Massachusetts and Rhode Island — with Woman-owned Business Enterprise certification in Massachusetts and New York providing preferential access to public-sector procurement. Named projects include Boston University (Center for Computing and Data Sciences, Agganis Arena), Brown University (Brook Street Residences), Northeastern University (ISEC), Boston College (Cadigan Hall), Museum of Fine Arts Boston, Encore Boston Harbor, and Winthrop Center, alongside numerous K-12 schools and municipal buildings.

The firm is a Massachusetts corporation with no external private equity or venture capital backing, controlled by its two co-founders who together hold 60 years of combined experience in building energy modeling. Revenue is generated through professional services engagements billed on a project basis. ALE is a Corporate Member of the US Green Building Council and leverages its credentials (four professional engineers, two Certified Energy Managers, three LEED APs, one ASHRAE BEMP) and project portfolio as primary competitive differentiation. The firm markets primarily through its website portfolio, industry relationships, and word-of-mouth within the regional AEC community.

Broad incumbents

• PAE Consulting Engineers: Full-service MEP engineering consultant with strong sustainability, energy modeling, and commissioning practices serving higher-education, civic, and commercial clients. Comparable to ALE on energy modeling and commissioning, but broader in mechanical/electrical engineering scale.
• ME Engineers: Global MEP and sustainable building engineering firm with energy modeling and commissioning services for institutional and high-performance buildings. Comparable to ALE on energy modeling and commissioning, but at meaningfully larger scale and broader geographic reach.
• BuroHappold Engineering: International engineering consultancy with sustainability, energy modeling, and commissioning practices serving cultural, higher-education, and large commercial projects. Comparable to ALE on energy modeling and institutional clients, but operating at far larger scale and global footprint.
• Karpinski Engineering: Cleveland-based MEP engineering firm with deep higher-education and healthcare building portfolios, including energy modeling and commissioning. Comparable to ALE on higher-ed and institutional client focus, but broader mechanical/electrical/sustainable design scope.

Direct peers

• Elementa Consulting: Mechanical engineering and sustainable building consulting firm specializing in energy modeling, commissioning, and decarbonization retrofits for higher-education and institutional clients in the Northeast. Closely comparable to ALE on service mix and customer type.
• Atelier Ten: Specialist sustainability and high-performance building design firm delivering energy modeling, daylighting, and MEP consultancy for institutional and commercial clients. Directly comparable to ALE in focus on computational building performance and LEED-aligned work for higher-education and cultural clients.
• Integrated Design Group (IDG) / Integral Group: High-performance building engineering consultancy offering energy modeling, commissioning, and zero-net-energy design. Comparable to ALE in its depth of energy modeling expertise and its higher-education and mission-driven client base.
• 7group: Sustainability and building performance consulting firm that co-authored the 2030 Palette and supports LEED, zero-net-energy, and green building certification work. Comparable to ALE on green building consulting and energy modeling for institutional clients.

Others

• New Buildings Institute (NBI): Nonprofit working on zero-net-energy and high-performance building codes, policy, and technical resources. Adjacent to ALE because both push forward the practice and regulatory environment for building energy modeling, but NBI is a thought-leadership/policy organization rather than a competing consultant.

Emerging players

• RJC Engineers (R.J. Burnside) / Sustainable Buildings Group: Engineering and building science practices offering energy modeling and sustainable building consulting for institutional and commercial clients. Comparable to ALE on energy modeling and LEED consulting, though with a different geographic footprint (Canada-focused).
