Championing the
Changemakers

The deadline for submitting presentations is coming up. This year ASHRAE is hosting a joint conference with Simbuild. We are just about to send out an extension announcement (It is now Feb 9th) , so there is still time to get an abstract for a presentation. 

Possible ideas for topics: 

Daylight - new metrics and... Read more

I'm hoping for some help answering the question of whether buildings/communities should pursue net-zero energy on site versus investing in new renewable energy (i.e. through the electric utility) that can be built at a more efficient scale elsewhere in the state. Our utility is asking us this question as we are working through how to get the... Read more

Welcome to the quiz portion of Toxic Chemicals in Buildings: How to Find and Avoid the Worst Offenders (recorded webcast).

Learning Objectives
Upon completing this course, participants will be able to:


1. Explain how key health hazards and opportunities for healthier choices vary by product category.
2. List... Read more

The BuildingGreen Guide to Thermal Insulation provides detailed guidance on insulation products and practices, including recommendations on what insulation to use and what to avoid. It's a treasure trove of information for architects and designers, builders, and anyone who is actively considering the impact of insulation on the quality of your... Read more

If you haven't seen it yet, today's U.N. report "Making Peace With Nature" tackles climate change, biodiversity loss, and pollution jointly within the framework of the Sustainable Development Goals. 

The analysis is anchored in current economic, social and ecological reality and framed by economics and the 2030 Agenda for Sustainable... Read more

Question for you all: there is this wonderful graph showing how we can shift mechanical and electrical dollars into envelope investments to make deep energy savings cost-neutral. Have you experienced this on a project?

1-minute or less survey! (two questions, more detail if you want)

Hi all - has anyone worked on a project with thermal energy storage tank design in the scope?  I'm wondering if anyone has recommendations for specialists or engineers who have experience.  Thanks!

I was sitting in on the USGBC's monthly Advocacy call this afternoon and heard about a state-local policy proposal to use property tax incentive for GHG reductions.  Through a state-local partnership, owners of existing residential and commercial buildings who invest in qualifying outcome-based improvements would receive a property tax...

Hello Gurus,

I am working with an owner who is making zero-carbon commitments and wants to explore setting carbon budgets in their capital plan (and subsequently their individual projects). We will be starting exploratory discussions next week and I was hoping some of you might have been working with other owners who have already... Read more

I am looking for case studies/trying to identify buildings using concrete mixes with upwards of 30% replacement of cement by SCMs.  I've been in conversations with some structural engineers who are interested in lowering embodied carbon in upcoming projects, but would like to see examples of where this level of replacement has been successfully...

Does adding solar panels reduce a building's EUI?

Existing operational use of a building is 80 kBtu/sf/year. When we add solar, it will change the source of energy but does not change the usage.

My understanding is that the EUI does not change, but it would be good to hear from others.

It's energy consumption at the point... Read more

I'm looking to compare using an electric tower crane vs a diesel generated tower crane.  I've got the average gallons/hour for the size of crane I'm looking at, but when I reached out to the crane manufacturers, they can only tell me what size electric supply I need to provide, not the kWh usage for the cranes.  I know that it varies depending...

Does anyone have experience pursing SITES certification on an essentially a zero-lot line project?

We are required to achieve silver certification, but the project scope/phasing recently changed and the entire site/parking area was eliminated and we no longer have a green roof. It still appears we can meet silver certification as so few... Read more

Board insulation has good thermal performance ranging from about R-4 to R-8 and is used as an integral part of a building envelope’s continuous insulation system.

Because board insulation is used on the building exterior, it is not always subject to the same material health and emissions requirements as batt insulation used inside the... Read more

The Center for the Built Environment (CBE) at the University of California, Berkeley is conducting a survey to understand current practices and outlooks among design practitioners: architects, engineers, energy modelers, and related professionals. Our goal with this work is to improve climate change adaptation guidelines that support building... Read more
