Design and Construction Process

The Massachusetts Maritime Academy consists of 16 buildings comprising approximately 600,000 sf, with heating for the buildings is provided by gas fired hot water boilers in each. They have undertaken a planning effort and initial design for a distributed campus-wide ground source heat pump system, combined with extensive energy retrofits. The plan consists of a neutral temperature Energy Transfer Loop that will tie various geo-exchange systems together to feed heat pump plants in each building.

Have you heard about the building standard that's not a standard? Learn how to create energy efficient, healthy, sustainable homes with an emphasis on making the concepts and technical details accessible to builders and designers of all levels of development. Two of the four co-authors of the Pretty Good House Book will go through the essential elements of what makes a Pretty Good House and share how it can help make low-carbon energy efficiency more accessible to contractors, designers, and clients.

Electrification of HVAC systems and the elimination of fossil fuel heating in high rise building space conditioning systems poses unique design and system selection challenges.  Presenters will share two case studies for the design of VRF HVAC, one using air-to-air systems and one using air-to-water systems. They will discuss challenges including maximum piping lengths, acoustical restrictions, and airflow problems, and solutions including closely spaced condensers using CFD analysis and the design of access to piping and wiring in large condenser farms.

While the 2021 International Energy Conservation Code (IECC) is already being used by some states, wider adoption is anticipated with the initiation of DOE’s Resilient and Efficient Codes Implementation (RECI) program. This session highlights key changes in the IECC and identifies 2024 proposals that will have the biggest impact on reaching emission goals. The presenters will explore the relationship between required codes and voluntary standards, as well as the adoption status of Model Code and Stretch Code in Massachusetts, New York State and New York City.

Electrifying the manufacturing process of building materials is a critical step towards decarbonizing the built environment. Going where no companies have gone before, two leading edge companies share their journey to reduce the carbon impact of their product. Each will tell their story on their path to decarbonizing their manufacturing process. This is the prologue, and the episode continues as they stretch their goals.

We will present tales from the trenches for ventilation approaches within the context of the Passive House building certification standard. This standard has set a high benchmark for low-energy buildings and is widely known as the most rigorous energy efficiency standard currently available. Attendees will learn how balanced ventilation is best applied in a cold climate at a large scale and how commissioning plays a key role in this process.

Bruce Becker is the architect, developer, owner, and operator of Hotel Marcel. He will discuss the conversion of the formerly vacant Pirelli Building in New Haven into Hotel Marcel, a 165-room LEED Platinum all-electric boutique hotel and conference center which is the first Passive House certified hotel in the United States. The discussion will include electrification (no fossil fuels including 100% of HVAC, hot water, kitchen, and laundry), power over Ethernet (POE) for all Lighting and Shades, and micro-grid creation for resilience with 1 megawatt-hour of battery storage.

Concrete accounts for approximately 11% of annual global carbon emissions. It is a material too important to ignore. Learn how BU’s Center for Computing and Data Sciences applied low-carbon concrete goals and selected structural elements to reach the highest Portland replacement concrete in Boston to date. See how opportunities in design, construction and supply chain were used to substantially decrease the climate impact of concrete used. Then discover national and local low-carbon material initiatives that are underway and growing.

VEIC’s work on Zero Energy Modular (ZEM) homes has helped hundreds of low and moderate income families achieve dignified, resilient, low-carbon housing. Over the past decade, we’ve partnered with five factories and countless funding partners and lending institutions to make this happen. The need is growing, not fading—for workforce housing, farmworker housing, Accessory Dwelling Units, mobile home replacement, affordable housing communities (single- and multifamily), and more. The problem? The ZEM model does not scale well within the current paradigm.

Public school projects are a highly visible commitment from a community towards future generations, serve a wide range of students from diverse backgrounds, and are a valuable resource to the surrounding community. This case study will show three projects that aimed to fit within the goals and budget of a public institution while focusing equally on energy, carbon, water, and waste. Linking the strategies for each goal to impacts on the health and well-being of students provides a new framework for evaluating the impacts of design.

Operational carbon is challenging but attacking embodied carbon is a complete nightmare! How can firms streamline the deadly research drain and get compliance across all teams for low carbon, healthy material choices? Owners, how can you set and ensure compliance with your standards when onboarding design teams? Builders, how can you leverage your buying power to accelerate market transformation through aggregation without having to change any behavior?
