Multifamily

Active Design is an evidence-based approach to the development of buildings and communities that uses architecture and urban planning to make physical activity and healthy foods more accessible. Affordable housing represents an ideal target for incorporating these strategies, since lower-income communities are disproportionately affected by obesity and chronic disease, and often have less access to health-supporting resources. This multi-disciplinary panel will share how Active Design supports healthier housing for people of all incomes and abilities.

Fairfax Gardens was a 150 unit dilapidated public housing development in Taunton, MA. The THA selected Trinity Financial to be the developer, owner and operator of a 160 unit replacement program on two sites. The Hope VI Program requires a very competitive funding application that includes strong sustainability incentives measured using Leed and/or Enterprise Green community checklist criteria. The Fairfax Gardens funding application was successful in part because it committed to very aggressive energy conservation measures.

In 2011, Somerville launched a city-wide residential energy efficiency program aimed at a difficult-to reach demographic: middle income rental properties. Efforts to reduce residential energy consumption with its dense population required numerous alliances: utility leaders, a banking institution, and consultants worked closely together. Over 60% of Somerville households are occupied by tenants; renter/owner roadblocks were addressed. This presentation will examine municipality, utility and resident collaborations necessary to make such a program succeed.

The use of utility bills to benchmark building performance is a critical first step in any approach to energy conservation. However, utility bills can only tell you so much about how to improve building performance. Five multifamily buildings received circuit level electricity, temperature, and CO2 monitoring equipment. The data identified inefficient mechanical designs, incorrect installations, poor maintenance and individual apartments with high energy use. We will review what we measured and what we learned, including energy savings as a result of this monitoring strategy.

This session will look at the basic shapes of aluminum and fiberglass products used for frames, and identify the basic principles to be used to develop functional details for both new and retrofit construction. We will isolate the heat, air, and water control layers in windows and connect those in precast, solid masonry, and framed walls. Issues of structural support, construction sequencing, building movement, and high humidity interiors will be addressed. Numerous examples and case studies rich with photographs and drawings will be used.

Central ventilation systems in multifamily buildings are a vital building system that often compromises overall building performance (ie they don’t perform to code almost 100% of the time). Correcting ventilation problems can produce significant energy savings in multifamily buildings while also improving occupant comfort and health. Central ventilation system restoration is an emerging energy retrofit that has had its bumps along the way.

Do you understand moisture dynamics? Do you have a comprehensive plan to control moisture in your buildings? If you answered no to either question, then you run the risks of occupant discomfort, mold growth, excessive maintenance and/or premature building failure. This session will help you avoid these risks. A veteran building scientist and co-author of the EPA Moisture Control Guide will share key measures—from design through operations—for controlling water and moisture in buildings.

The role of a building's structure, and of the structural engineer, in achieving sustainability goals is frequently marginalized. Yet it represents a majority of a new building project's material mass and embodied energy, and is responsible for a large portion of its CO2e emissions. It can also play a role in the annual energy usage of a building, both in good ways (i.e. thermal mass) and bad (i.e. thermal bridging).

 Why do we need to pay attention to behavior in buildings? You can design a building to the highest energy efficiency codes and specifications, but once it’s occupied, what happens to affect the baseline? People who have done deep retrofits and ZNEB projects can find these efforts undermined if occupant behavior is not addressed. Occupant engagement should ideally address several stakeholder groups, including landlords, facilities management, lessors, and tenant employees. Each of these falls under the label of “engagement” but requires a different approach.

Never get the R-15 wool insulation pulled over your eyes again! Separating green from greenwash is getting harder as standards proliferate. Tristan and Paula from BuildingGreen bring you the latest in clever greenwash with this lively and interactive chat on what makes a label truly green. Even if you come knowing nothing about green building labels, you'll leave with new knowledge--as well as new wisdom. We'll show you how to ask the right questions and make your own judgment next time a company tries to convince you that its pet metric or label is the greenest of them all.

Advances in building envelopes and HVAC equipment enable widespread use of air source heat pumps by many in the "Net Zero Energy" and "Passive House" movements. Steve Bluestone will report on two related items: a three year performance study of an air source heat pump system using hourly measurements (done with Henry Gifford and built above his garage) and the design and construction of his new 101 unit high performance rental building in NYC utilizing the same technology.

With the drop in envelope loads and the rise in efficient heat pumps (even in cold climates), quite a few homes are moving away from fossil fuels towards electric HVAC. One recurring question is: what to do about water heating? This session covers various options - simple electric tanks, tankless electric heaters, solar thermal, heat pump water heaters, etc. - and presents real cost and energy data from several research & evaluation projects.

A number of multifamily affordable housing developments in the New York City area were hard-hit by Superstorm Sandy in 2012. Affordable housing organizations have learned from that experience and are working to improve the resilience--and sustainability--of their facilities, in ways both large and small. Alex Wilson and Jim Newman have been facilitating some of this work. This session reports on these efforts and presents practical strategies for making multifamily affordable housing--and all multifamily buildings--more resilient.

For many teams, it is an almost impossible challenge to simultaneously deliver high performance and cost efficient buildings while maintaining high customer satisfaction and profitability. Integrated design/build delivery providing single responsibility, from schematic design to construction through commissioning and monitoring has proved to be a viable model for successful delivery of cost efficient high performance buildings. This session will examine aspects of planning, marketing, estimating, system development, project management, human resources, accounting, and legal concerns.
