Type of Building Code

Type of Building Code

• Cooling Based
• Prescriptive Codes
• Trade Off

  Total building envelope UA (U-factor multiplied by area). This is the path predominantly used by the REScheckTM software. Based on the prescriptive U-factor table, it allows trade-offs whereby some energy-efficiency measures can fall below code requirements if balanced by other measures that exceed code requirements.

• Performance Codes for New Builds
• Energy Declaration
• Model / reference Building

  Compliance based on simulated energy performance requires that a proposed residential residence (proposed design) be shown to have an annual energy cost that is less than or equal to the annual energy cost of the standard reference design. Such analysis shall include heating, cooling, and service water heating energy only. Commercial - using total building performance.

  Residential - All circulating service hot water piping shall be insulated to at least R-2. Circulating hot water systems shall include an automatic or readily accessible manual switch that can turn off the hot water circulating pump when the system is not in use. Minimum pipe insulation requirements. Commercial - Water heating equipment and hot water storage tanks shall meet the requirements of Table 504.2. The efficiency shall be verified through data furnished by the manufacturer or through certificatio

• Technical installations

  Residential - In all buildings having individual dwelling units, provisions shall be made to determine the electrical energy consumed by each unit by separately metering or monitoring individual dwelling units.

• Lighting

  Residential - A minimum of 50 percent of the lamps in permanently installed lighting fixtures shall be high-efficacy lamps. Commercial - requirements for lighting system controls, the connection of ballasts, the maximum lighting power for interior applications, and minimum acceptable lighting equipment for exterior applications. In General, Lighting designs must meet a stringent watts per square foot thresholds.

• Appliances
• Design, position & orientation of building
• Heat recovery

  Commercial - Energy recovery ventilation systems. Individual fan systems that have both a design supply air capacity of 2.36 m3/s or greater and a minimum outside air supply of 70 percent or greater of the design supply air quantity shall have an energy recovery system that provides a change in the enthalpy of the outdoor air supply of 50 percent or more of the difference between the outdoor air and return air at design conditions. Condenser heat recovery shall be installed for heating or reheating of ser

• Passive solar

  It is not actively encouraged.

• Passive cooling

  It is not actively encouraged.

• Natural ventilation

  It is not actively encouraged.

• Solar protection

  It is not actively encouraged.

• Daylighting requirements

  Daylight zones, shall be provided with individual controls that control the lights independent of general area lighting. Contiguous daylight zones adjacent to vertical fenestration are allowed to be controlled by a single controlling device provided that they do not include zones facing more than two adjacent cardinal orientations

• Renewable Energy (solar, PV, others)

  Partially, to the fullest extent feasible, use of modern technical methods, devices and improvements which tend to minimize consumption of energy and utilize to the greatest extent practical solar and other renewable sources of energy without affecting reasonable requirements for the health, safety and security of the occupants or users of buildings shall be permitted.

• Local renewable sources
• Energy Offsets/Green Certificates

Enforcement

Type of Enforcement

• Local enforcement
  The code enforcement official shall examine or cause to be examined the accompanying construction documents and shall ascertain by such examinations whether the construction indicated and described is in accordance with the requirements of this code and other pertinent laws or ordinances. The building shall have a final inspection and not be occupied until approved.
• Third party inspection
  Approved inspection agencies. The code enforcement official is authorized to accept reports of approved inspection agencies, provided such agencies satisfy the requirements as to qualifications and reliability. The third party inspection must be performed by a New York State licensed and registered architect or professional engineer.
• Central enforcement
• Accreditation of applicants
  A registered design professional shall provide to the code enforcement official a written certification that the required HVAC tests, system balancing, etc., have been performed and that, in the professional opinion of the registered design professional, the system is operating as designed. The registered design professional shall retain copies of the test reports to be provided to the code enforcement official, if requested.
• Post Occupancy control

On-site Inspections Occur

• On-site inspections
• During construction
• Post completion
  The building shall have a final inspection and not be occupied until approved.
• Post occupancy

Certification to Support Enforcement of Code

• Energy Performance Certificate support BC
  Partially, permanent certificate shall be posted and should list the predominant R-values of insulation installed in or on ceiling/roof, walls, foundation (slab, basement wall, crawl space wall and/or floor) and ducts outside conditioned spaces; U-factors for fenestration. Where there is more than one value for each component, the certificate shall list the value covering the largest area. The certificate shall list the types and efficiencies of heating, cooling and service water heating equipment.
• Positive labeling for building beyond the minimum BC level
• Existence of EPC register database at national level
• Inspection of boilers
  Boiler system completion inspection.
• Inspection of HVAC systems
  HVAC system completion inspection. Prior to the issuance of a certificate of occupancy, the design professional shall provide evidence of system completion, duct leakage testing.

Penalties for Non-compliance

• None
• Fine
• Imprisonment
• Refusal of permission to occupy
• Refusal of permission to construct
  Energy code compliance must be demonstrated in the application for a permit. If the applicant cannot demonstrate compliance, then the applicant cannot obtain a building permit. Some permits are issued based on self certification by the professional. Those jobs are randomly selected for audit. If the job fails the audit, then the permit receives a stop work order.
• Demolition

Measures Supporting Enforcement

• Commissioning requirements
  Buildings that are 50,000 sq ft or larger must perform an Energy Audit and retro-commissioning every 10 years. For more information, please see: http://www.nyc.gov/html/gbee/html/plan/ll87.shtml"
• Airtightness testing required prior to compliance
  Resdential - Mandatory building envelope air tightness and insulation installation shall be demonstrated to comply with one of the following options, Building envelope tightness and insulation installation shall be considered acceptable when tested air leakage is less than seven air changes per hour (ACH) when tested with a blower door at a pressure 50 Pa or Building envelope tightness and insulation installation shall be considered acceptable when field verified by an approved party.
• Mandatory Computer Modeling
• Training of Inspectors
  Dept of Buildings inspectors are trained internally. NYSERDA offers courses for free. There is currently no requirement for specialty training for third party inspectors.
