Improving the efficiency of existing buildings and eliminating fossil fuel usage are vital steps to meeting states' goals to reduce greenhouse gas emissions throughout New England. Focusing on finding scalable and replicable models for building typologies, such as triple deckers, will help reduce greenhouse gas emissions, as well as increase tenant comfort and reduce energy bills. This session focuses on the best ideas and lessons learned from MassCEC’s Triple Decker Design Challenge.

The virtual power plant - aggregated, behind-the-meter solar, energy storage, and building loads dispatched in concert to meet grid needs - is a new model that has been pioneered in New England and is now being adopted by forward-looking utilities and policymakers across the country. This session will explain why the virtual power plant is the future of energy storage, how states can create virtual power plants using existing programs and budgets, and why this is an important new paradigm that will benefit customers and communities.

Beach Green Dunes I and Beach Green Dunes II are two of the largest multifamily Passive Houses in the country. They are adjacent to each other in the Rockaways in NY (in the flood zone) and were completed two years apart. Although they look almost identical, they are very different under the hood. Each has a different structure, envelope (ICF vs Block), ventilation strategy (Unitized vs Centralized), and heating and cooling system (VRF vs. ground source heat pumps) along with several other differences due to changes in city regulations and varying site conditions.
