What you need to know
Why Hire a Building Envelope Consultant
Here are 3 key situations when you should hire a building enclosure design and consulting services firm:
During the Design Phase of a New Building
If you’re designing a new building, a consultant can help ensure the building envelope is energy-efficient, weather-resistant, and meets local codes.
For Energy Efficiency Upgrades or Sustainability Projects
If you want to reduce energy consumption, a consultant can help you design a building envelope that minimizes heat loss or gain.
When Renovating or Retrofitting an Existing Building
Older buildings often have outdated or inefficient building envelopes that need upgrades for better energy efficiency and comfort.
The building envelope industry is filled with countless products and often influenced by ill-informed or biased sources. In today’s design landscape, having a knowledgeable and detail-oriented professional is essential to help clients make technically sound and cost-effective decisions
HCG provides a comprehensive range of building enclosure design and consulting services, supporting clients from initial investigations to final construction and beyond.
