Our new methodologies, tools and guidance will build on the previously developed SDA methodology for buildings to develop 1.5°C-aligned resources. In particular, the Buildings project aims to achieve three objectives:

Most existing residential and commercial buildings located in cold climates are not constructed to resist the corrosion and excessive moisture accumulation that can result from long-term, whole-building humidification. If additional winter humidification is used to maintain comfort and prevent excessive dryness of nasal and ocular membranes, first analyze the building enclosure to verify that condensation and moisture accumulation will not become a problem. ASHRAE Standard 160 (Criteria for Moisture-Control Design Analysis in Buildings) provides guidance for hygrothermal analysis of building enclosures. For commercial buildings that are properly constructed to allow for long-term humidification, and which have humidification capabilities already installed, there is no reason not to humidify the air to comfortable levels during the winter months.

The Department of Buildings enforces the Chicago Building Code to protect the health, safety and welfare of Chicago's residents and visitors. The Department issues all construction and demolition permits in the City of Chicago. The Department also cites potentially hazardous buildings, encourages repair through enforcement action, and coordinates demolition when necessary. The Department of Buildings is also responsible for examining and licensing select building trades.

The life span of a building can be 50-100 years, meaning our existing buildings will be around for decades to come. To meaningfully reduce building emissions, we need stronger energy use standards. The 2019 Clean Buildings Act created energy performance standards for commercial buildings larger than 50,000 square feet. Mandatory compliance begins in 2026.

Commerce conducted 15 workshops and comment periods from 2019 through 2020 to establish the new standard and set state-specific targets that are 15% less than 2009-2018 averages. The targets are based on data showing the average energy use for commercial buildings larger than 50,000 square feet as well as the downward trend in energy use resulting from new technology and maintenance or operation practices. Examples include the replacement cycle of lighting to LEDs and trends in building tune-ups and operations.

On March 25, 2022, Governor Inslee signed the Clean Buildings expansion bill into law. The expansion applies to buildings 20,000 square feet or larger, adding a new second tier that includes multifamily buildings.

The first phase of this law is not a performance standard. It will require reporting on benchmarking, energy management plans and operations and maintenance programs for Tier 2 buildings. Compliance and reporting for this new tier is expected July 1, 2027.

Concern about indoor exposure to mold has been increasing as the public becomes aware that exposure to mold can cause a variety of health effects and symptoms, including allergic reactions. This document presents guidelines for the remediation/cleanup of mold and moisture problems in schools and commercial buildings; these guidelines include measures designed to protect the health of building occupants and remediators. It has been designed primarily for:

It should serve as a reference for potential mold and moisture remediators. Using this document, individuals with little or no experience with mold remediation should be able to make a reasonable judgment as to whether the situation can be handled in-house. It will help those in charge of maintenance to evaluate an in-house remediation plan or a remediation plan submitted by an outside contractor1. Contractors and other professionals who respond to mold and moisture situations in commercial buildings and schools may also want to refer to these guidelines.

Molds can be found almost anywhere; they can grow on virtually any organic substance, as long as moisture and oxygen are present. There are molds that can grow on wood, paper, carpet, foods, and insulation. When excessive moisture accumulates in buildings or on building materials, mold growth will often occur, particularly if the moisture problem remains undiscovered or unaddressed. It is impossible to eliminate all mold and mold spores in the indoor environment. However, mold growth can be controlled indoors by controlling moisture indoors.

Since mold requires water to grow, it is important to prevent moisture problems in buildings. Moisture problems can have many causes, including uncontrolled humidity. Some moisture problems in buildings have been linked to changes in building construction practices during the 1970s, 80s and 90s. Some of these changes have resulted in buildings that are tightly sealed, but may lack adequate ventilation, potentially leading to moisture buildup. Building materials, such as drywall, may not allow moisture to escape easily. Moisture problems may include:

When mold growth occurs in buildings, adverse health problems may be reported by some building occupants, particularly those with allergies or respiratory problems. Remediators should avoid exposing themselves and others to mold-laden dusts as they conduct their cleanup activities. Caution should be used to prevent mold and mold spores from being dispersed throughout the air where they can be inhaled by building occupants.

The Clean Buildings Performance Standard is mandatory for Tier 1 buildings located in the state of Washington. A Tier 1 building (formerly known as covered commercial building) is a building where the sum of nonresidential, hotel, motel and dormitory floor areas exceeds 50,000 sq. ft, excluding the parking garage area.

Data Verification is the process we use to correct information about misidentified buildings. Data verification can be done through the Clean Buildings Portal below. If you own multiple buildings and only some of those buildings need to comply, submit your application through the Portal.

Misidentified buildings include:Structures that are not actual buildings (e.g. docks and piers); buildings that are less than 50,000 sq. ft; or if you are not the owner of the building.

ABB proudly contributed to the development of two carbon-neutral apartment buildings in Maennedorf, Switzerland. With home and building automation solutions renewable electricity is produced by the buildings through photovoltaic.

Buildings and facilities must be accessible to people with disabilities under the Americans with Disabilities Act (ADA) and the Architectural Barriers Act. Accessibility standards issued under these laws govern the design, construction, and alteration of many types of buildings and sites in the private and public sectors.

The ABA Accessibility Standards apply to facilities that are funded by the federal government. This includes federal buildings, such as post offices, social security offices, federal courthouses and prisons, and national parks, as well as other facilities that receive federal grants or loans, such as public housing units and mass transit systems. The Access Board provides technical guidance and training on the ABA Standards. It also enforces compliance with ABA Standards through the investigation of complaints.

COP27 is a critical moment for the buildings and construction sector to showcase solutions for climate action and all stakeholders along the built environment value chain to unite as one voice towards building decarbonization and resilience.

The Buildings Pavilion is a space for businesses and policymakers to interact, a meeting place for buildings and construction community, and a space to showcase solutions through events, exhibitions, awards, etc. From 8 to 17 November, the Buildings Pavilion will be hosting over 50 events in line with the daily themes interconnected with the COP27 Presidency and Marrakech Partnership for Global Climate Action (MPGCA) agendas.

Elevated objects such as roof outlines in aerial imagery may appear displaced with respect to the base of the structure. In order to minimize or eliminate the effects of such displacement (often referred to as "building lean"), MassGIS undertook several automated processing steps to shift roofprint polygons as delivered by Rolta. Building lean effect may cause some buildings to cross over into adjacent parcels or overlap other features such as streets and water bodies. The shifting process was performed only in areas where MassGIS' LiDAR Terrain Data were available (Eastern Mass. inside of I-495; for details see the section "Adjustment Method" below). As a result, many of the shifted polygons better approximate building footprints.

The red line in the above image is the "seam" between two different photos. The buildings on either side of this line are from different photos, so the buildings seem to lean away from their respective principal points.

I also cowrote Healthy Buildings: How Indoor Spaces Drive Performance and Productivity (Harvard University Press; 2020, re-released in 2022 with a new chapter on pandemic resilience) with John Macomber. Building on the mission of the Healthy Buildings Program, we combined our expertise in the fields of public health, urban resilience, commercial real estate, and building science to show the impact buildings have on our health and performance, and how every indoor environment can be made healthier for the people inside. 2b1af7f3a8
