Robert Derector Energy and Sustainability (RDE)

RDE provides independent analysis to help end-users, building owners and data center operators understand how they use energy and what they can do to use less.

Our services include:

  • Energy Modeling for Commercial Tenants
  • LEED v4 Energy Modeling
  • Building Energy Audits and Retro-Commissioning (Including for NYC Local Law 87)
  • Energy Modeling for NYC Energy Conservation Code (NYCECC) Compliance
  • Renewable and Alternative Technology Feasibility Analysis
  • Corporate Energy Strategy Consulting

Our Approach

Throughout our work we strive to distill clear pragmatic advice from technical detail. We have found this to be highly effective in helping decision makers to quickly see both the strength of a business case, and whether a specific energy saving measure makes sense for their current situation.

NYSERDA Incentive for Tenant Fit-outs

Tenants in New York can get 50% off our energy modeling service under the NYSERDA Commercial Tenant Program. This is a great way to deliver high performance (low running cost) tenant space; allowing ideas to be tested out virtually before committing to them in practice.

RDE is an expert on energy modeling of tenant space, and was modeler for three of five pilot projects NYSERDA ran while developing this program:

  • White & Case LLP: a 440,000 square foot high performance tenant fit-out at 1221 Avenue of the Americas.   Open PDF
  • Paul Hastings LLP: a 190,000 square foot high performance tenant fit-out at 200 Park Avenue.   Open PDF
  • Gensler NYC: a 125,000 square foot high performance tenant fit-out at 1700 Broadway.   Open PDF

LEED v4 Energy Modeling

Energy modeling can be used to achieve up tp 28 points for Commercial Interior projects in LEED v4.

NYSERDA FlexTech Incentive

Our clients in New York can get up to 50% off on our fees for energy analysis. FlexTech pays up to 50% of the fee for qualifying studies, with no obligation to implement any of the measures analyzed.

Certified Energy Auditors (CEA)

We have Certified Energy Auditors on staff. Between RDE and our international partner hurleypalmerflatt, we have helped drive down energy costs at over 700 buildings worldwide since 2005.

In New York City, buildings covered by Local Law 87 are now required to have energy audits undertaken by a qualified professional (such as a CEA).
