PropTech OS: Next-Generation Building Energy Telemetry.

Developing an automated IoT & cloud platform for heat substation monitoring, predictive maintenance, and energy efficiency.

Currently in R&D and Pre-Seed stage — seeking grant funding, innovation support, and strategic pilot partners across Vilnius.

About the Project

AVAKONA is a Vilnius-based PropTech and engineering company dedicated to digitizing heat substation management, telemetry, and automated utility administration across Lithuania and Central Eastern Europe.

Traditional building management often relies on fragmented manual inspections, reactive emergency repairs, and complex utility accounting. AVAKONA was founded to change that.

Combining deep expertise in heating system hydraulics, substation maintenance, and modern cloud software engineering, we built PropTech OS—a unified platform designed to make building infrastructure transparent, energy-efficient, and fully automated.

Market Potential & ROI

  • Addressable Market: Over 30,000 district heat substations in Lithuania and 1.5M+ across CEE requiring mandatory digital energy monitoring under EU EPBD directives.
  • Proven Financial ROI: Cuts operational and maintenance overhead by up to 25% for DNSB housing cooperatives through automated telemetry and early fault detection.
  • Environmental Impact: Reduces thermal energy losses by 15–20%, directly lowering heating expenses and operational carbon footprints.

Core Pillars of Expertise

Practical Heating Infrastructure Expertise

We understand physical heat substations, circulating pumps, and control valves from the inside out, allowing us to build software that truly solves daily field challenges.

Proprietary Telemetry & Cloud Architecture

PropTech OS collects 24/7 data from heat nodes, running predictive diagnostics to catch equipment anomalies before failures occur.

Lithuanian Regulatory & Billing Engine

Built-in accounting models calculate heating and service fees proportionally based on area and municipal regulations, automating mass invoicing and client communications.

EU Decarbonization & Efficiency Alignment

Our data-driven algorithms support EU Green Deal directives by optimizing thermal energy consumption and reducing operational carbon footprints.

Validation & Pilot Status

  • Active Pilot Deployment: Undergoing real-world testing across residential & commercial properties in Vilnius.
  • Protocol Compatibility: Seamless integration with standard heat substation hardware via M-Bus and Modbus protocols.
  • Proven Efficiency: Real-time telemetry monitoring actively reducing thermal losses and downtime.

Whether serving housing management companies (DNSB), commercial facility operators, or municipal heating networks, AVAKONA provides a scalable, hardware-agnostic solution that reduces operational costs and guarantees full compliance with energy regulations.

IoT & Smart Telemetry

Real-time monitoring of heat substations, temperature sensors, and equipment parameters.

Automated Maintenance

Streamlined work orders, technician scheduling, and regulatory compliance reporting.

Energy & Cost Optimization

Data-driven analytics reducing heating losses, downtime, and operational overhead.

Automated Accounting & Billing

Proportional fee calculations, automated invoicing, and full compliance with Lithuanian reporting standards for housing management companies.

Empowering Property Managers with Smart Automation

PropTech OS bridges the gap between legacy heat substations and modern cloud technology. Our platform enables housing management companies and technicians to monitor heat nodes in real time, predict equipment failures, and optimize energy consumption across entire building portfolios. By turning manual maintenance into data-driven workflows, we help operators cut energy losses and reduce operational costs.

Market Problem & Urgency

The District Heating Challenge in CEE

  • Aging Infrastructure: Over 70% of heat substations rely on manual control systems, leading to unmonitored energy losses and emergency failures.
  • Technician Shortage: Housing management companies face rising operational costs due to a shortage of qualified field technicians.
  • EU Energy Mandates: The EU Energy Performance of Buildings Directive (EPBD) obliges building operators to digitize energy monitoring and reduce emissions.

Sustainability & ESG

Driving Sustainability & EU Green Deal Alignment

  • 15–20% Heating Energy Saved: Smart algorithms optimize supply temperature schedules based on real-time weather, eliminating overheating.
  • Reduced CO₂ Footprint: Direct energy savings cut fossil fuel consumption across district heating networks.
  • Extended Hardware Lifecycle: Predictive maintenance prevents major pipe bursts and extends equipment life by up to 30%.

Lithuanian Compliance & Billing Engine

Full Administrative & Billing Automation for Property Managers

  • Proportional Fee Calculations: Automated allocation of heating and maintenance costs strictly based on building floor areas and municipal formulas.
  • Mass Digital Invoicing: Instant invoice generation and email distribution to apartment owners and commercial tenants.
  • Regulatory Compliance: Reporting templates fully aligned with Lithuanian state energy inspectorates, municipal requirements, and local heat network standards.

Business Model & Expansion

Scalable B2B SaaS Platform

  • Recurring Revenue: Scalable B2B SaaS subscription model for housing management companies combined with IoT telemetry integration.
  • Rapid Integration: Designed for quick deployment across housing cooperatives (DNSB), commercial real estate, and municipal facilities.
  • Baltic & EU Expansion: Pilot deployment in Vilnius with engineered scaling across the Baltic States and Central Eastern Europe.
  • Product Roadmap & Milestones
  • Q3 2026: IoT Telemetry Integration & Pilot Testing across Vilnius Properties
  • Q4 2026: Rollout of Automated Billing & Lithuanian Regulatory Compliance Engine
  • Q2 2027: Commercial SaaS Expansion to Baltic Housing Cooperatives (DNSB) & Facility Operators
  • Q4 2027: Scaled Rollout across Central Eastern Europe (CEE) Region

Built for Housing Management Companies & Facility Operators

PropTech OS solves the critical operational challenges faced by property management companies, heating service providers, and facility operators across Lithuania and the EU. By integrating real-time telemetry from heat substations into automated field workflows, our platform helps operators reduce emergency downtime, meet strict EU energy efficiency mandates, and streamline communication with property owners.
