Building Energy Performance Standards are being introduced throughout the Northeast, including Boston’s BERDO 2.0. Commercial Property Assessed Clean Energy (C-PACE), already adopted by several states, can act as a ‘carrot’ for property owners to make the necessary capital improvements to meet these requirements. With C-PACE, property owners can access low-cost, long-term, fixed-rate financing for measures that impact the energy and water performance of their commercial or multi-family properties.

While more residential customers have turned to heat pumps as an efficient alternative to electric resistance heating, to shift away from delivered fuels, or to add cooling to their home, the modest gains in heat pump penetration have largely been limited to single family homes. This session presents the findings of a barrier study for heat pump adoption in multifamily properties, which have not experienced similar growth in heat pump adoption.

Windows and glazing play a disproportionate role in a building's performance compared to other parts of the assembly.  As we strive to meet our 2030 and 2050 climate goals the design strategies for both our new and existing buildings must be closely evaluated.

We will present the IAQ monitoring program at the Finch Cambridge passive house development, first year results, and lessons learned at Finch and in attempting an IAQ monitoring program at another site.  IAQ monitoring in all common spaces and some apartments includes CO2 and radon, and in all apartments and common spaces total VOCs, temperature and humidity.  We will share the first 18 months of IAQ data for Finch and findings relative to temperature, CO2, humidity, and total VOCs.

While Massachusetts  and many communities have made commitments to achieve carbon neutrality by 2050, Boston and Cambridge specifically are on the leading edge of implementing requirements around existing building emission reductions. Emissions tracking has started to move building owners toward benchmarking their carbon impact and developing long-term plans for compliance, with an eye toward minimizing costs.

A large number of effective multifamily energy programs have supported retrofits at thousands of properties in the last decade. The next generation of multifamily programs, however, must catalyze the decarbonization of almost all existing buildings over the next 2-3 decades. With the increasing urgency of the climate crisis, and new Building Performance Standard policies creating strong local imperatives, how will energy programs go both deeper and broader than those of the past?

Sustainability in lighting is usually linked to energy use only, but it is time to face the real challenges of quantifying the impact of design decisions made throughout the product life cycle. While we may not have complete information on life cycle impacts, we cannot afford to wait until comprehensive information is available to inform our specification decisions. This presentation will provide a framework for weighing operational energy use, embodied carbon, and material impacts.

While project teams typically establish quantifiable performance targets for their projects, there is no magic bullet for defining the right energy consumption goal for each project. This panel of high-performance experts and architects will discuss strategies for quantitative goal setting: when, who, and how aggressive.

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.

To achieve our 2050 climate goals we must go all-electric. But how do we get there? For new construction, all-electric solutions are increasingly viable. However, all-electric solutions for existing buildings are considerably more challenging. The upfront cost to upgrade old buildings to a level that ensures efficient (and economical) performance can be prohibitive.
