Explain how second generation buildings are becoming net-zero energy or carbon neutral. How are they different from first generation LEED buildings?
In my opinion, second generation green buildings address what really matters…climate change. Net-Zero Energy or Carbon Neutral buildings are buildings that have zero or very minimal greenhouse gas emissions in the long term operation of the building. This means that other sustainable features within the LEED grading system are already incorporated, such as thermal comfort, indoor air quality, views/daylighting, recyclable content, etc. Design professionals and developers should already have a handle on dealing with these requirements, but the focus should now be on carbon emissions.
What are some of the biggest challenges when trying to build net-zero energy or carbon neutral buildings?
The largest challenge is always going to be economics. Finding ways to design and build Net-Zero or Carbon Neutral buildings that meet the client’s budget is difficult. Long term benefits though are very attractive for clients and they are often willing to invest in the capital cost of the building.
What are trends should the construction industry be looking at in 2016 in regards to second generation LEED buildings?
There will be more and more Net-Zero or Carbon Neutral buildings. Design teams along with developers will continue to work together to find financial/economic solutions.
