The Maple West project was funded in part for the incremental costs of building and monitoring an affordable multi-unit residential building (MURB) at NZE/NZEr level with solar power renewable energy. The goal was twofold; first to demonstrate and test an affordable and replicable solution for MURBs to achieve the NZE/NZEr performance level and secondly to develop a generic simulation tool to predict and analyze the aggregate energy profile of highly energy-efficient MURBs with a distributed solar PV system connected together on a community level.

Landmark Homes is already a recognized leader in energy efficient homes having built 28 NetZero Energy (NZE) homes, over 50 NetZero Energy Ready (NZEr) homes and 250 highly energy efficient solar homes across Alberta, touting on average a minimum 15% better than the building code requirements.

“The project will demonstrate a viable NZEr MURB solution for Alberta housing industry and provide a ready-to-use tool to assess the impact of NZE and NZEr buildings to community micro-grid.”

Project Innovation

MURB NZE/NZEr with Community Level Solar Power Generation

The project will be utilizing high-performance envelopes as well as optimized electrical mechanical systems to create energy efficiency in the units. Included in this is the use of a dual-fuel combined space and hot water heating systems, air source heat pumps, tankless water heaters, indoor air handlers, and high velocity small duct distribution system. Watch the shared learning webinar to learn more.

Power Use Prediction Tool

The power use prediction tool will use actual energy profile data from the project and develop a neural network model to identify the key variables impacting the building loads in relation to the electrical grid. A forecast model will be developed to predict the aggregative energy profile at a MURB level. This model will be validated through overlaying the energy consumption and solar generation profiles developed using the historical data from other MURB projects and solar PV systems.
