Energy Management

T.M. Bier and Associates offers a full range of energy management services including, energy auditing, retro-commissioning, Local Law 87 (LL87) compliance, and Real Time Energy Management (RTEM) using Building Analytics.  Our team of Licensed Professional Engineers, Certified Energy Managers, Certified Building Commissioning Professionals and Controls System Engineers are experts in energy cost reduction.

Many building owners and operators want to improve the efficiency of their facility to reduce costs, attract higher level tenants, and meet rising standards of green building operation. Your building’s overall energy efficiency is affected by many things: air distribution, heating, cooling, lighting and controls. Making all of these systems work efficiently together within your facility is a challenge to say the least.

TMBA is a leader in assisting companies to “Go Green” and conserve energy. Today, it is more important than ever to conserve energy, not only to protect our environment, but to minimize cost.

Find out today how TMBA can be your one stop shop for all your energy efficiency requirements, whether you operate a commercial office building, hospital, or residential building.




Retro Commissioning is the process of identifying what is not right with a system in today’s environment and making the necessary changes. Retro-Commissioning gets your building working the way it needs to NOW versus the way it worked in the past under different circumstances. TMBA quickly analyzes the environment and provides up to date recommendations and implementation.

Energy Analysis & Engineering

One of the major energy costs in operating a building is the HVAC system, usually comprising 40% or more of all electrical consumption. TMBA Engineers have a depth of knowledge and experience that is not customary in most HVAC companies. The first thing to be done to analyze the energy efficiency of a building is to complete an Energy Star Benchmarking.


We offer the following energy-saving devices:

Variable frequency drives Process field instrumentation such as temperature and pressure transmitters, flow meters, and indoor air quality monitoring

Control valves and actuators

Condition-monitoring equipment and systems

Pumps and motors

Local Law 87

TMBA provides complete compliance solutions for the audit, retro commissioning, and reporting portions of Local Law 87 of the Greener, Greater Buildings Plan legislation. The audit provides building owners and managers complete information and analysis to make sound financial decisions regarding energy saving opportunities. Our ASHRAE Level II energy audit will help you comply with the law and identify energy projects that will meet your financial criteria. The required retro commissioning generally provides a 1-2 year payback.

TMBA not only advises you on compliance but provides a concise presentation of your energy improvement options with a solid business case. Each potential measure is defined in terms built around sound financial metrics and the asset valuation impact.

Local Law 87 Requirements

  • Must perform an ASHRAE Level II Energy Audit of base building systems:
    • HVAC
    • Conveying
    • Domestic hot water
    • Electrical and lighting
    • Building Envelope
  • Must perform retro-commissioning of base building systems to correct deficiencies.
  • Must file an Energy Efficiency Report (EER) by compliance date, which outlines audit findings and corrective action taken. EERs are due every 10 years. The energy audit and retro-commissioning must be performed during the 4 years prior to submitting the EER.
