What Greenmetrix OÜ does

Greenmetrix OÜ is a Tallinn-based sustainability consulting firm established in 2024 that advises property owners, developers, and investors across the Baltic states (Estonia, Latvia, Lithuania) on green building certification and environmental compliance. Its core services include LEED and BREEAM certification consulting, EU Taxonomy alignment advisory, 3D energy modeling and simulation, energy efficiency assessments, and Building Life Cycle Assessment (LCA) under the EU Level(s) framework and Estonian national methodology. The firm combines architectural, climate, HVAC, and occupancy data into models that identify cost-neutral material substitution opportunities — for example, replacing structural steel with 99% recycled hollow section steel on the Koplipere tee 5 project, which cut the building's carbon footprint from 415 to 320 kg CO₂/m² without raising construction cost.

The company operates as a project-based professional services firm, generating revenue through bespoke consulting engagements priced by scope, certification level, and building complexity. Customer acquisition is consultative and relationship-driven: prospective clients engage via the website inquiry form, referrals, or direct outreach, and Greenmetrix acts as a strategic partner from early design through GBCI/USGBC submission. Primary client segments are real estate developers and property owners/investors, with secondary demand from financial institutions needing green-loan technical assessments and ESG reporters requiring CSRD/GRESB-aligned building-level data.

Greenmetrix is majority-owned (80%) by real estate investor Marko Kull of Millerhawk, with founder Kairi Nõulik serving as CEO and retaining the remaining stake. The five-person team includes LEED BD+C AP-accredited specialists, and the firm has built its brand around landmark Baltic firsts — Estonia's only LEED O+M Platinum shopping center (Viru Keskus), the country's first residential LEED Gold building (VEKTOR), and the first LEED-certified commercial building in Saue city (Saue Smart). Marketing is content- and credibility-led, relying on thought-leadership publishing, industry media appearances, and reference projects rather than paid acquisition.

Products and services

• LEED Certificate Consulting LEED (Leadership in Energy and Environmental Design) certification consulting services that guide property owners and developers through the full green building certification process — assessing energy efficiency, water usage, indoor air quality, and material selection, from initial strategy through documentation preparation and final GBCI/USGBC submission. Targeted at real estate developers and property owners in the Baltic region seeking LEED Certified, Silver, Gold, or Platinum certification.
• Consultation (BREEAM and Sustainability Advisory) Initial sustainability consultation services for property owners and developers who need guidance on creating action plans aligned with their goals to improve energy efficiency, reduce environmental impact, or improve user satisfaction. Covers BREEAM-aligned advisory and serves as the entry point for clients beginning their sustainability journey.
• EU Taxonomy Advisory Consultation services on EU Taxonomy requirements for new building developments, assessing compliance with climate change mitigation criteria, including primary energy requirements and greenhouse gas emission calculations. Helps property developers make assets future-proof and qualify for better green financing terms.
• 3D Energy Modeling & Simulation Detailed 3D energy modeling and simulation services that assess building energy efficiency, identify savings opportunities, and test different energy efficiency measures and technological solutions. Models incorporate architectural features, climate conditions, material properties, window/door specifications, and HVAC systems to simulate energy efficiency and model various occupancy scenarios.
• Energy Efficiency Assessment Building energy consumption analysis and assessment services that include data analysis, technical system reviews, maintenance inspections, indoor climate measurements, and energy label calculations. Helps owners and developers make informed decisions about energy efficiency improvements to achieve energy savings, cost reduction, and reduced environmental impact.
• Building Life Cycle Assessment (LCA) Life cycle assessment services based on the EU Level(s) framework or Estonian national methodology to calculate building carbon footprint across material production through end-of-life waste processing. Identifies environmental impact reduction opportunities and enables data-driven material substitution (e.g., recycled steel replacing structural steel) to reduce building carbon footprint without additional construction cost.

Quantifiable outcome

• Carbon footprint reduced by one-third (from 415 kg CO₂/m² to 320 kg CO₂/m²) for Koplipere tee 5 residential building — equivalent to an improvement from environmental class D to C under Nordic methodology — achieved through material substitution with no additional construction cost
