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.

By law, the NHPUC is required to develop a program using a portion of the Renewable Energy Fund (REF) to directly benefit LMI residential customers. The Low-Income Community Solar Act of 2019 provides an additional 2.5 cents per kwh for the development of LMI community solar projects. To date, a handful of these projects have been built in NH, including Mascoma Meadows Cooperative in Lebanon and Keene Housing Authority in Keene. The Organization for Refugee and Immigrant Success is currently under development.

Residential Energy Efficiency programs are poised to see a shift in scope from weatherization to decarbonization that will include deeper retrofits and strategies to eliminate fossil fuels in and outside the home.  This panel will discuss the skills and expertise needed in the workforce to decarbonize our residential building stock and contemplate how we will train and fill for these positions, looking at diversity, barriers, and feeder programs.

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.

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.

With many states incentivizing housing built to the Passive standard, everyone wants to know: are Passive-certified multifamily buildings really achieving better energy performance? The answer is yes. With many built multi-family passive projects throughout the Northeast, there are now multiple occupied projects where we can look at actual energy performance data, sometimes over multiple years. Using Passive project data from built projects in MA and PA, we will compare post-occupancy performance and cost to similar above-code and code built projects.
