Energy Modeling & Building Performance Analysis
The cheapest energy is the load you design out early. Powerkh runs whole-building energy models, daylighting, and thermal simulations from your BIM to guide design decisions and support LEED and ASHRAE 90.1 compliance, all off-site from the model you already have.

Building Energy Modeling & Simulation Services
Building energy modeling is the simulation of how a building uses energy, using a virtual model of its geometry, envelope, systems, and climate to predict heating, cooling, lighting, and total consumption. It guides early design choices, sizes HVAC loads, and supports LEED and ASHRAE 90.1 compliance documentation.
Energy modeling replaces guesswork with numbers. By simulating a building against real climate data, an analytical model shows how orientation, glazing, insulation, shading, and system choices change heating and cooling demand, daylight availability, and annual energy use. Run early, it lets a design team compare options while changes are still cheap, and run late, it produces the documentation that green rating and code compliance require. Either way it turns performance from an afterthought into a design input.
Powerkh has delivered 400+ BIM and VDC projects for US, UK, and EU clients since 2018, and we apply that rigor to performance analysis. We take your Revit or gbXML model, build an analytical energy model, and run whole-building simulation, daylighting, and thermal and HVAC load studies to your ASHRAE 90.1, LEED, or local code targets. This is desktop simulation work run entirely off-site from your model, not an on-site energy audit or field measurement. We price by the hour with a free quote, deliver reports you can act on, and sign an NDA on request.
Why Choose Powerkh for Energy Analysis
Straight from your BIM
We derive the analytical model from your Revit or gbXML geometry, so simulations reflect the real design and update as it evolves.
Early-design optimization
We compare envelope, glazing, and orientation options while changes are inexpensive, so performance shapes the design rather than reacting to it.
Compliance support
We structure models and reports to support LEED energy credits and ASHRAE 90.1 baseline comparisons for your submissions.
Free quote, pay after delivery
You get an hourly estimate before we start and pay only once the analysis is delivered, with an NDA available on request.
Our Energy Modeling Services
Whole-building energy modeling
Annual energy simulation of the full building to predict consumption, costs, and carbon against your targets and baselines.
Daylighting analysis
Daylight factor, illuminance, and glare studies to optimize glazing and shading and support daylight-related credits.
Thermal and HVAC load analysis
Heating and cooling load calculations from the model to inform system selection and equipment sizing.
LEED and green rating support
Energy models and comparison reports structured to support LEED energy credits and similar green certification pathways.
ASHRAE 90.1 compliance modeling
Proposed-versus-baseline energy models and documentation to support code and standard compliance submissions.
Early-design optimization studies
Comparative simulations of orientation, envelope, and glazing options to guide decisions in concept and schematic design.

FAQ
What do you need to start an energy model?
Your building geometry as a Revit model or gbXML export, the location or climate data, and your target standard such as ASHRAE 90.1 or a LEED pathway. Details on constructions, systems, and occupancy help; where they are unknown we apply standard assumptions and note them clearly.
Is this an on-site energy audit?
No. This is simulation work run entirely off-site from your digital model. We do not perform field measurements, blower-door tests, or on-site audits. We analyze the design or a modeled existing building using energy simulation software and deliver the results as reports.
Can you support LEED and ASHRAE 90.1 submissions?
Yes. We build proposed and baseline models and produce the comparison results and documentation used to support LEED energy credits and ASHRAE 90.1 compliance. Your accredited professional or reviewer submits and certifies, and we provide the modeling and reporting behind it.
When in the project should we run energy modeling?
Both early and late add value. In concept and schematic design, comparative studies steer envelope, glazing, and orientation while changes are cheap. Later, a detailed model produces compliance and certification documentation. We can support one phase or model iteratively across several.
How much does energy modeling cost?
Powerkh uses hourly pricing. After reviewing your model, target standards, and the analyses required, we provide a free quote with accurate hour estimates, and you pay only after we deliver the results. We sign an NDA on request.
