The following are examples of program development opportunities completed by L&S Energy Services.
Development of the CHP Component of the Existing Facilities Program
Dr. Landsberg and Mr. Slosberg supported the development of the CHP component of the Existing Facilities Program and the recent update and re-issue of that program. This included:
In February 2013, L&S was one of three consulting firms requested by NYSERDA to participate in a comprehensive review and assessment of the new Combined Heat and Power program and the updated CHP Systems Manual. This work required developing comments to clarify the solicitation. L&S also developed recommendations for the program offer and suggested CHP Systems Manual. During several collaborative roundtable meetings with NYSERDA, L&S (and the other consultants) provided input into proposed program changes.
Review of Technical Feasibility Studies
L&S Energy reviews technical feasibility studies performed by other contractors as an outside reviewer. This includes review of the work scope, discussions with the technical assistance provider to refine the work scope and then review of the report. Projects include:
In the past three years this has included 219 studies reviewed or in progress.
Participation in the Development of the Green Jobs Green New York Program
L&S Energy has been part of the task force developing the Green Jobs Green New York Program. This has included:
Participation in the NYSERDA IT Efficiency M&V Working Group
The purpose of the IT Efficiency M&V Working Group is to develop a Measurement & Verification (M&V) protocol that will be used to define energy efficiency of IT equipment and data optimization strategies on a “per unit of useful data processed” basis. This protocol will be applied to projects as part of NYSERDA’s Data Center focus within the Industrial and Process Efficiency program.
Tasks for this effort included:
The metrics and M&V protocol developed in tasks 2 and 4 took into consideration present day technologies and be realistic to those limitations.
2008 Energy Code Cost Effective Study for Priorities
L&S Energy provided cost effective analysis on changes to the energy conservation code. These included:
Each study consisted of the following tasks:
Each code change was modeled in several building types under different operating schedules and utility rates. The purpose was to evaluate effectiveness of the code change.
Energy Efficiency Guides for Existing Buildings
L&S Energy Services was contracted by ASHRAE to produce the Energy Efficiency Guide for Existing Buildings. This is the first in a series of ASHRAE guides targeted at existing buildings. The purpose of the first volume is to make the business case for building owners and managers. The second volume is targeted at building managers and engineers.
The sections include:
Inspections of Energy Star Buildings and CHPs Schools
L&S Energy Services performs reviews for facilities seeking Energy Star recognition. Facility energy usage and equipment is documented and scored by another entity in a Statement of Energy Performance (SEP). L&S verifies the SEP and inspects the facility to ensure that occupant comfort has not been compromised to achieve energy savings. Unlike most building inspections, this one focuses on occupied space more than mechanical systems. Inspections include items such as:
If the SEP and occupant comfort levels are confirmed and acceptable, a professional engineer from L&S stamps the SEP and approves the facility for Energy Star recognition.
Energy Star inspections have been performed on NYSERDA headquarters in Albany and 37 school buildings to date.
L&S was one of the outside reviewers on the development of New York CHPs. NY CHPs is targeted to school buildings and is more focused on the needs of NYS schools than LEED. L&S participated with other members of the review committee to review draft sections of NY CHPs. We participated in review meetings with NYSERDA and the New York Education Department.
L&S has also performed CHPs reviews for two school districts.
Evaluation of Solid State Lighting (LEDs)
Solid State Lighting utilize light emitting diodes (LEDs) to the light source within the lamp. Benefits of LED lighting include long-life and reduced energy use. However, market barriers include high initial cost and lack of product diversity (fewer lamp options). Currently, NYSERDA provides incentives through EFP and IPE for lamps that are found on the Energy Star or Design Lights Consortium listings. At present there are few, if any, linear or tubular LED lamps on either of these two product lists. Several manufacturers have begun to make and market LED lamps that are ‘pin-compatible’ with standard T-8 lamps.
L&S has completed evaluations of linear LEDs at eight customer sites. Barriers to implementation were high initial cost, unfamiliarity with technology, uncertainty of replacement availability, lack of firm and verifiable data on energy savings and lamp life.
The consulting services provided by L&S included
Evaluation of Liquid Refrigerant Pumping
From 2011 to 2013, L&S evaluated several Liquid Refrigerant Pumping applications. The objectives of our work were to concisely evaluate the energy savings and economics of this under-utilized technology.
For many commercial and industrial refrigeration systems, supplying excess refrigerant to the evaporators will result in an increase in heat removal capacity. Pumping refrigerant from the condenser to the evaporator coils allows a significant reduction in system head pressure. Lowering head pressure results in a reduction in compressor loading (bhp). This approach is commonly referred to as liquid refrigerant pumping.
L&S evaluated the application of Liquid Refrigerant Pumping at 3 facilities:
Liquid refrigerant pump for 125-ton chiller, payback 3.4 years
4 liquid refrigerant pumps, 35 hp total, payback 2.1 years
4 refrigerant pumps, liquid refrigerant pump payback 2.8 years
M&V Data for Compressor kW over 2 weeks
L&S completed comparative measurement and verification of the liquid refrigerant pumps. Our engineers install real-time recording meters to track electric usage every five minutes. Ambient (outdoor) temperatures were also recorded at the same intervals. By completing a thorough before vs after comparison of the electric use (in total and also in pattern), L&S develop various regression equations that characterized performance. Total electric savings, extrapolated to an entire year, were then calculated.
Anaerobic Digester Gas-to Electricity Program (ADG Program)
ADG systems are an under-utilized technology. There were 610 Waste Water Treatment Facilities in New York State registered with DEC, as of 2004. According to the Cornell Cooperative Extension there are 5,400 dairy farms in New York State. At over 6,000 potential facilities, ADG is a technology well worth considering for accelerated commercialization.
The NY State Service Commission authorized funding for an ADG to Electricity Program. The funding and program are administered by NYSERDA. Waste water treatment plants and dairy farms produce sludge and manure. These byproducts can be cycled through an anaerobic digester to produce methane gas. The gas is conditioned and burned as fuel in an engine-generator. The electricity from the engine-generator is used to power the facility, and feed back to the grid. Exhaust heat from the engine-generator is used to heat the digester and other areas.
L&S Energy Services provides technical consulting services to NYSERDA for the ADG program. L&S assists in application review, writing and reviewing measurement and verification (M&V) plans, review of requests for incentive payments, site inspections and general technical support.
L&S is currently assisting several sites in New York State including:
