Green Building Principles
The City of Newton has written a bold Climate Action Plan to address the urgent need to mitigate climate change. If the City is going to meet its climate change goals, it must have a strong green building policy to match.
Indeed, buildings account for 39% of worldwide CO2 emissions: 28% for building operations and 11% for buildings’ embodied energy. Hence, we must decarbonize our buildings to avoid climate catastrophe.
With recognition of the climate crisis, and the progress made in green building practices and policy, Green Newton calls for the City of Newton, and all governments, to use the following principles to evaluate and guide building projects.
The Passive House Building Standard for Boston should be the standard for all building types. Passive House qualified buildings have very low energy use intensity (EUI).
Embodied carbon is the carbon dioxide produced by the manufacture and transportation of building materials. In other words, it’s “the carbon dioxide released when we construct our buildings in the first place.”
Given that the carbon footprint of construction can far outweigh the carbon footprint of operations over the first few decades of a building’s lifecycle, it’s critical that we pay attention to embodied carbon when designing and planning new buildings and renovations.
Thoughtful design and materials selection minimizes embodied carbon. For example, buildings that use less concrete and steel and more engineered lumber reduce their carbon footprints. Such buildings should be favored by City building officials.
It can be cumbersome to estimate the embodied carbon of a new building, but it’s getting easier. Good tools include Revit plug-ins, Environmental Product Declarations (EPDs) and on-line calculators.
Here is a helpful resource.
New construction should be fossil fuel free.
Most new buildings can achieve zero fossil energy use when they are built. Excellent electric equipment is now available to provide heat, domestic hot water and cooking. Heat pump technologies and food preparation technologies like induction cooktops are used worldwide today and have favorable lifetime costs.
New buildings that unavoidably include fossil fuel consumption need a feasible plan to transition to achieve zero carbon by 2040. The zero-carbon plan should identify fossil fuel equipment and include a narrative describing the equipment that will replace them. The plan should describe how the building design accommodates the space, access, and electrical requirements of the anticipated equipment.
All-electric buildings can be fully carbon neutral when owners or occupants purchase 100% renewable electricity.
The carbon footprint for transportation used by building occupants and customers is also significant. Building owners must facilitate low-carbon modes of transport, such as bicycles, electric vehicles, walking, and public transportation.
The City can help by reducing or eliminating parking minimums, and instead specify parking maximums.
