New Construction Impact Evaluation
 Ft. Collins Residential Energy Code
Evaluation
The Heschong
Mahone Group, along with RLW Analytics, is
conducting market research and energy analysis to evaluate the effectiveness of the
residential energy code that was implemented in Fort Collins in 1996 and characterize
residential air conditioning in Fort Collins.
The market research task addresses the perceptions and experiences of the builders
related to the energy code change and the homeowner’s perceptions and reality related
to home comfort, energy costs, value and quality.
The energy analysis task addresses the effect the energy code change and related
support efforts have on energy usage and provides a comparison of the energy projections
based on detailed models, and actual metered energy.
Impact Evaluation of
SMUD’s Residential New Construction Program
For the Sacramento Municipal Utility District (SMUD), subcontractor to
HBRS, Inc. We
developed the on-site survey and simulation strategy to evaluate their residential new
construction program. Our innovative approach recognized that builders construct multiple
versions of a given plan. Detailed on-site surveys were conducted for one model per plan,
followed by simple sidewalk surveys for other examples of the plan. A DOE-2 simulation
model was then customized to the orientation, shading conditions and other parameters of
each house. With this approach, a detailed engineering estimate of savings was generated
for many more houses within the given budget.
Impact Evaluation of SMUD’s
Commercial New Construction Program
For the Sacramento Municipal Utility District (SMUD), subcontractor to ADM Associates.
We conducted telephone surveys of decision makers (building owners, managers, architects
and engineers) responsible for energy efficiency decisions in participant buildings. We
achieved a near 100% response rate. Also we conducted engineering reviews of all sampled
projects to determine energy baselines and measure efficiencies for all parameters used in
the DOE-2 simulations. These reviews provide the key assumptions that determine the
effectiveness of program measures in the impact evaluation.
Impact Evaluation of PGE's Commercial New
Construction Programs
For Portland General Electric, conducted three impact evaluations: 1995-96 Commercial
New Construction (CNC), the 1992-94 Commercial Industrial Energy Efficiency (CIEE) and the
1990-92 Energy Smart Design (ESD) new construction programs. The projects evaluated
several measures including energy efficient lighting, high efficiency HVAC equipment, high
efficiency motors, envelope measures and adjustable speed drives (ASD’s) on HVAC and
process equipment. For each evaluation, we calculated net and gross energy savings. Each
evaluation used a slightly different approach, improving on the previous evaluation
methodology. The projects involved telephone surveys of decision makers, on-site surveys
to verify installation of measures, end-use metering, and DOE-2 analysis to validate
programs’ energy savings estimates. We were responsible for overall project
coordination, including analysis of results for estimating savings, and preparation of the
final report
