Technical Services

From design to construction, our technical services ensure projects meet specifications and that onsite adjustments do not compromise high quality standards.

Energy Models

Energy models analyze a building design to estimate energy use. They are often used to inform decisions on efficiency features, prioritizing those that are most cost effective. They can also provide:

• Energy Costs

• GHG Emissions Reductions 

• Access to Financial Incentives

• Code Compliance Reports (RESCheck, COMCheck)

• Energy Rating Index (ERI)

• Home Energy Rating System (HERS) Score

HVAC Manual J Calculations

HVAC systems are commonly oversized. This causes humidity and comfort problems and can reduce the life of the system.. Manual J Calculations are essential to correctly-size your HVAC system. This important step is required by building code in many places, but not enforced. The result? Oversized systems that do not meet building code.  

We understand the details required for accurate calculations and common pitfalls for systems in humid climates. Let us help you manage HVAC system costs and improve comfort with a Manual J Load Calculation.

Full HVAC Design with Ventilation

We partner with the best in the business to provide full HVAC Design services including ventilation and make-up air. This includes Manual J, S, D, and T calculations to ensure peak performance of your HVAC system. 

Performance Testing

Blower Door and Duct Testing

Blower door and duct leakage tests measure air leakage of the building envelope and ductwork. These tests are required in new construction to meet building codes, and to earn Energy Star and National Green Building Standard certifications.

In existing buildings, these tests are used to establish a pre-retrofit baseline and to find big leaks that are causing comfort problems, moisture issues, and high energy bills.

Ventilation and Filtration Assessment

Ventilation and filtration are key considerations for indoor air quality management. A ventilation and filtration assessment is included for all projects pursuing Energy Star and Indoor Air Plus certifications. It’s also a standalone service for clients who suspect a problem with their current set-up, or just want to improve indoor air quality.
