Xcel Energy has clarified the program requirements for the ENERGY STAR for New Homes program.  Currently, the eligibility requirements for this rebate program are as follows:

• Residential unit (home) must be actively serviced by Xcel Energy natural gas in the State of Colorado
• At least one individual residential gas meter per unit/home must be installed and metered directly by Xcel Energy
• Structure must receive a qualified HERS rating, by an approved rater (Populus Sustainable Design Consulting is an approved rater in the program) and be submitted/approved by a RESNET HERS Provider in good standing (Populus handles this part for our clients)
• Homes that are connected to, and/or adjoin “conditioned common space” are not allowed (example: apartment buildings with interior hallways, foyers, and/or elevator shafts are not eligible)

In addition, Residential Science Resources, the company that administers the rebate program on behalf of Xcel Energy, has announced some upcoming changes to the Xcel ENERGY STAR for New Homes program, which are coming in 2010 (a specific date has not been announced):

• All participating homebuilders will be required to become an active ENERGY STAR partner (this is free of charge) as well as complete an online survey and release of data form.  The purpose of these requirements are to help Xcel Energy increase the marketing of ENERGY STAR homes throughout the state.
• Providing all homes participating in the program with no cost ENERGY STAR yard signs throughout the home’s construction.  Xcel Energy will provide signs at no cost to participating homebuilders adn arrange for installation and removal for each sign based on the construction dates provided by the HERS Raters (please provide Populus with construction dates to take advantage of this part of the program).
• $1,000 rebate per home that has a Whole House Evaporative Cooler installed as part of the ENERGY STAR New Homes Program.

A recent American Institute of Architects (“AIA”) study highlights the national trend toward green building programs since 2007.  According to an AIA survery, more than one in five U.S. cities (with populations of more than 50,000) report having programs in place that promote green building.  This number represents a 50% increase in municipal green building programs over the last two years.  The Western and Mountain regions lead the nation in the number of green building programs per state.  Given the size of the cities with green building programs, the impact of these sustainability programs reach about 53 million people.

To find out more about these sustainability and green building initiatives throughout the nation, see the AIA’s new report, Green Building Policy in a Changing Economic Environment, which also contains policies and recommendations to assist policymakers in advancing sustainability and green building.  You’ll also find case studies that highlight the green building programs in several cities, including Boston, Philadelphia, LA and Grand Rapids.

In light of the economic downturn during the last two years, AIA Executive Vice President / CEO, Christine McEntee, finds the results of the AIA’s survey encouraging and a sign “that cities are recognizing the economic benefits of energy-efficient buildings.”  The AIA is a prominent adopter of the 2030 Challenge and has committed to a goal of carbon neutral (zero energy) buildings by 2030, in addition to its goal that “all design projects will be sustainable as a matter of course.”

What impact does window selection have on energy efficiency and sustainability?  What factors influence the energy performance of windows?  Populus Sustainable Design Consulting and SolarGlass Window & Door presented on these issues at last year’s USGBC Colorado Sustainability Conference.  Here is a description of that presentation:

The session will explain the implication of the DOE’s pending 2009 Energy Star changes for high altitude markets and review the product design responses planned by leading manufacturers.  Additionally, the session will discuss the interplay of the following factors on building envelop efficiency, sustainability, and occupant comfort: glazing to floor area ratios, dispersion of windows by elevation, glazing alternatives, frame materials, the often overlooked importance of quality installation

Attendees will come away with an understanding of what design elements should be given priority when developing a window solution for a given project, as well as the trade-offs associated with aesthetic, performance, and price considerations.

Included in the presentation will be an overview of the growing importance of performance-based measurements of building envelop efficiency (e.g.; Resnet’s Home Energy Rater modeling software) and how windows impact the HERS score.

USGBC Colorado has recently posted Populus & SolarGlass’s “Sustainable Window Selection” presentation on its website.  Of particular interest, on page 11 of the presentation, you will find a graph which demonstrates the specific concerns and trade-offs related to window selection for various ranges of desired HERS Index Scores.  Pages 13-18 contain a case study which analyzes the interaction of window selection and mechanical systems as it relates to home energy performance.
