The most obvious benefit of the Passive House standard is a dramatic reduction in energy costs. Using the Passive House design methodology and energy-modeling software, architects can save building owners up to 90% on heating costs compared to a typical existing building. In addition buildings built to this standard have superior thermal comfort—warm in winter and cool in summer with no drafts. A side benefit of using high-performance windows and air sealing is reduced noise from the street and from neighboring apartments. The proper architectural details can provide for acoustic insulation and energy efficiency.
Due to the expense of submetering and market expectations, owners of multifamily rental buildings in New York usually pay for heating their tenant’s apartments in addition to the common areas. By law landlords are required to provide heat between October 1 and May 31. This can be a significant expense, so developers often ask their architects to design energy-efficient buildings.
Tenants in condominium buildings often have their own heating equipment in the unit and are responsible for their own heating bills. One of the reasons condo buyers are attracted to green buildings is that they can save a lot of money on their utility bills. If the energy savings are significant, as with a certified Passive House building, the developer’s initial investment will pay off with a higher sales price.
As an architect who has worked on townhouses in Brooklyn and Queens, as well as larger apartment buildings in Manhattan, Gregory Duncan understands the potential this type of building has for huge increases in comfort and energy savings. See our article on Passive House in New York City which explains how this green building standard is in many ways easier to achieve in New York than many other places.
Of course, the Passive House energy-efficiency standard applies to commercial and single-family houses as well. So, no matter what building type you are planning, a Certified Passive House Designer can help you make it better.
