HPC Responds to the Direct Testimony of Randall Short - West Virginia Public Service Commission

The Home Performance Coalition (HPC) recently wrote Hon. Michael A. Albert, Chairman of the West Virginia Public Service Commission in response to the September 15, 2017 Direct Testimony of Randall Short in Case No. 17-0401-E-P, which reaches the extraordinary and unsupported conclusion that with the proposed EE/DR programs “from an economic perspective, customers are better off if the proposed programs are denied.” (Short Testimony, Page 7).

HPC believes that the economic conclusions…

New Home Builders Tackle Zero-Energy Home Building in Connecticut

Connecticut’s 2016 Zero Energy Challenge reinforces the growing interest in the zero-energy home building movement. In addition to increased participation among experienced homebuilders, the 2016 challenge had an influx of inexperienced zero-energy home builders trying their hand at zero-energy homebuilding for the first time, with two winning.

How did they do it?

3 Issues HVAC contractors Should Know About Impacting Customer Comfort and Health

There is an epidemic of people suffering in many of the 100 million homes across the U.S.  Many of your customers are living in uncomfortable and unhealthy homes, and are wasting money trying to heat and cool their homes.

Even after HVAC contractors have installed higher efficiency, properly sized equipment in their homes, many are still getting call backs from customers because they have rooms and entire homes that remain too hot in the summer and too cold in the winter.  The HVAC…

Envisioning A Sustainable Green Market And Economy

Amazing Energy-Generating Buildings for the 2017 Astana World Expo (?)

  As interesting as the above vision is, we have to ask our selves if the cost of construction to realize the artistic vision of this building, will in any wise be recovered by its projected energy generation capabilities?  For the most part I can see a need for lots of interior cooling and have to ask where the source or power for this is coming from? …

MPG for Homes - The Quest for the Best

An mpg-like rating for homes is here. For the first time in history, people can find out the expected energy use of any home in the U.S. This single piece of information conveys helpful insights including the expected cost of maintaining a home, the environmental impact of the home, and a proxy for how comfortable the home is likely to be. This information will become more widely available from more sources as…

Core Heat And Other Concepts

  In some places the use of solar heated liquids from hot water solar panels are used to provide heating for floors which are fitted with tubing in the floor to move the heated liquid through.  Heated liquid from hot water solar panels can also be sent to registers or radiators in remote places in a home such as its core.

  Another innovative way that heated liquids can be used is to move the liquid into a…

Applications Now Being Accepted for BPI's Jon Siemen Memorial Scholarship

The Jon Siemen Memorial Scholarship has been developed to honor the life, memory, and work of Jon Siemen, who passed away in March 2015. Jon started his career in weatherization in the late 1970s, when he began working at Community Action in Southwestern Vermont (BROC). Around 1993/1994, Jon and his brother started an air sealing service that they ran for a few years. In 1996, Jon joined the Champlain Valley…

The Btu And Geo Thermal Energy

  This is a novel exercise in innovative thinking, which might not seem practical in everyday use, but can have its application sometime, somewhere in the world.  What I want to do here is to look at another source of free renewable energy of the geo thermal kind, and get people to think of ways in which they can use this energy to reduce energy consumption…

How To Approach A Home Energy Design Scenario

  When you look at the way air conditioners work in terms of their efficiency, which is to say in terms of the amount of electrical power that is expend to remove a certain quantity of thermal energy in Btu terms, you realize that the air conditioner is much more energy efficient than a furnace.  And hence the concept of the heat pump as a heating system was born from the air conditioner concept because of the efficiency.  What…

How Much Attic Insulation Do I Need? If I want to build a passive solar heated home?

  I ask this question purely from the stand point of a green built home design where one is thinking of using passive and active solar heating.  This is for a new design and not for retrofitting into current designs.  Furthermore the kind of design I am thinking of utilizes a heat recovery ventilator, and since we can have thermal up drafts that lead air up wards to ventilate out of any crack in the ceiling, we might want to…

Affordable Energy Efficient Design With Initial Renewables

  A so called sustainable design is not sustainable cost wise on the market if its consumer cost falls into the hard to afford range of investments.  What I want to discuss here might seem opposite in some ways to the things we have been taught with regards to building for sustainability.  Many green building visions fall within the unsustainable cost column, where they have to be subsidized to recover their cost hence we can…
