Seminar Series - 2021

Seminar Series 2021 - DECARBONIZING HOMES

As part of our climate goals it will be essential to decarbonize homes. This seminar series examines some of the challenges, barriers and solutions. The focus is on hands-on experiences from homeowners, architects and contractors that are working on home electrification and decarbonization. We will begin with a summary of recent Lawrence Berkeley National Laboratory work for DOE on pathways to large-scale home decarbonization, including cost analyses from over 1,700 projects as well as surveys of industry professionals. We will hear from our Lawrence Berkeley National Laboratory colleagues who have decarbonized their homes, or are in the process of doing so. Finally, local contractors, architects and consultants will share some of their hands-on knowledge and ideas.

See the links below for information about the Seminar Series hosted by Berkeley Lab between Nov. 17th 2021 to January 5th 2022. All the slides and videos are available at the links below.

The series was hosted by Iain Walker, leader of the Residential Building System Group.

Can you DIY Home Electrification? (December 1st 2021)

Can you DIY Home Electrification?

December 1st, 2021 (12-1pm ET)

ABSTRACT

DIY approaches to home decarbonization are a great opportunity to engage with homeowners and to save a lot of the costs of upgrading a home.  In today's seminar,  we will hear from people who are trying out different DIY methods. They will share their successes and the various barriers they have faced. This will give us some insight on what parts of the home decarbonization process are the most challenging and will require extra efforts from a technical R&D perspective, as well as for the development of home decarbonization programs and strategies for getting to scale. It might even inspire attendees to try out a little DIY themselves.

Jonathan Woolley, PhD is president of Emanant Systems – a research consultancy focused on design and control of energy-efficient grid-interactive mechanical systems for comfortable and healthy indoor environments. Since 2004, Jonathan has been involved in a wide variety of research and design addressing energy efficiency in buildings. He has unique expertise with climate-appropriate hybrid cooling systems – with which he has experience in modeling, design, commissioning, and measured performance evaluation through both laboratory and field experimentation. As a PhD student with Center for the Built Environment at UC Berkeley, Jonathan utilized LBNL FLEXLAB to conduct a series of experiments with radiant cooling to assess fundamental limitations with industry standard cooling load calculations. Jonathan also has design and research experience with passive solar, natural ventilation, radiant cooling and heating, indirect evaporative cooling, advanced heat pump systems, heat recovery, occupancy sensing learning thermostat controls, and zero-net energy buildings.

How to Electrify your Homes Without Panel Upgrades (December 8th 2021)

How to Electrify your Homes Without Panel Upgrades

December 8th, 2021 (12-1pm ET)

ABSTRACT

Installing a home solar array, electric vehicle charger or an auxiliary dwelling unit (ADU) can often come with a hidden cost--$2k - $4k for a new 200 Amp overhead service wire, and $16k for a 200 Amp underground service wire.
 
Come learn how to decarbonize a home and personal vehicles while staying on a 100 Amp service. We'll review power-efficient appliances and cold climate heat pumps; load balancing 240V "plug strips," EV chargers, subpanels and main panels; and PV inverters that can "clip" extra PV.

He co-authored five practical guides to building electrification, provided legal and technical support to dozens of gas bans nation-wide, helped develop the 2016/2019/2022 and 2025 Title 24 California Energy Codes, and has received sustainable design awards from the United Nations, the U.S. Department of Energy and the SoCal Building Industry Association.

Planning, Designing and Installing Home Electrification (December 15th 2021)

Planning, Designing and Installing Home Electrification

December 15th, 2021 (12-1pm ET)

ABSTRACT

Consulting on home electrification projects is a highly variable exercise, ranging from a few phone calls or emails to a months-long engagement with homeowners and their design and construction teams. While different owner goals, budgets, and existing conditions make every project unique, this seminar will review the types of challenges typically encountered and some common steps to arriving at solutions, along with specific examples. The seminar will conclude with thoughts about how changes in the building industry might reduce friction in the electrification process.

Rapid Electrification of Existing Buildings: Problems and Opportunities (December 22nd 2021)

Rapid Electrification of Existing Buildings: Problems and Opportunities

December 22nd, 2021 (12-1pm ET)

ABSTRACT

Getting to scale with home decarbonization requires making it easy to do in ways that are fast, affordable and practical. A key barrier to home decarbonization is the time delay and cost associated with upgrading home electric services.  This seminar will discuss approaches that address these topics and provide solutions that are being implemented by industry leaders. This will include methods for planning home decarbonization, identifying key barriers for getting to scale and the "Watt Diet" concept for limiting the need for electric service upgrades.
