EXPERTISES
Evaluation of Existing Systems
Evaluating existing building HVAC systems involves assessing their performance, efficiency, and functionality to identify inefficiencies and opportunities for improvement. The process helps optimize energy use, comfort, and cost savings while meeting sustainability goals.
Equipment Schedule
An equipment schedule outlines the specifications, locations, and quantities of all equipment within a building or project. It ensures proper planning, coordination, and tracking of equipment for efficient installation and operation.
Utility Analysis
The Utility Analysis will be developed based on existing energy bills to understand as-built performance of the building and calibrate the thermal building simulation results.
ECM Evaluation and Simulation
Only “Energy Efficiency First” makes renewable supply feasible by reducing the overall energy loads, downsizing equipment and reducing investment and operation cost.
3D-Modeling
The 3D-Model will be built based on architectural design (incl. wall structure, u-values etc.) together with the surrounding high rises as precondition for a thermal simulation under realistic conditions.
On-Site Measurements
On-site measurements involve collecting data on U-values of windows, façades, roofs, and interiors, as well as performing ultra-sonic flow measurements. These measurements help assess energy efficiency and system performance for accurate building analysis and optimization.
Thermal Building Simulation
Thermal building simulation involves creating a digital model to analyze a building’s thermal performance, including heat flow, insulation, and energy use. It helps optimize energy efficiency, comfort, and sustainability by predicting how the building will respond to different environmental conditions.
Pipe Flow Simulations
The design work will be based on thermal building simulation, energy modeling and Pipe Flow Simulation.
Energy Modeling
The Energy Modeling is to optimize the dimensioning of the equipment for heat/cooling generation, storage and supply.
Energy Savings and CO2-Emissions
Evaluation of Energy Savings play a vital role in the development of Decarb Projects and Economic Feasibility. Local and federal regulations, ESG strategies and other relevant drivers are focusing on carbon emissions reduction.
Roadmap to Net-Zero
Every conception must pass an Economical Assessment by proving to be the most efficient approach in terms of capital expenditure and operational expenses.
