EXAMPLE PROJECT

Spectral’s smart building platform empowers our clients to perform detailed analysis of their electricity, gas and heat consumption and intelligently steer their building management system based on AI-driven forecasting. Spectral typically works in partnership with the client’s metering company in order to gather comprehensive real-time data and install sub-metering within the building(s).

The smart building platform is mainly developed in Python using various frameworks including Tornado, Flask, and gRPC. Data is drawn from multiple sources including the metering company’s API, from the on-site sub-meters (using industry-standard protocols) and from external APIs (e.g. for weather data). Much of this data is stored in a TimescaleDB time-series database. Data visualisations and other UI elements are implemented in JavaScript-based libraries to deliver secure, permission-based content for different user roles (e.g. board member, property manager, tenant) including a tailored dashboard for each user type.

Sophisticated algorithms extract business intelligence and recommendations for energy savings, peak shaving, etc. Our solution provides sophisticated building portfolio analysis, including the ability to apply advanced data filtering and display or compare (aggregated) data for multiple locations. The reporting module gives full flexibility with regards to the selected data and templating. The smart building platform enables automatic control of the building management system (using communications protocols such as BACnet) to optimise energy efficiency whilst providing a comfortable climate for the building tenants.

Example developer tasks related to the platform might be to devise and implement a new alert to detect sub-optimal processes running within the building, to develop a new library to interact with an external API or to optimise system performance via analysis and enhancement of the database and ORM layers.
