Energy News & Tech Tips. Project of the Quarter
Tech Tip: Modeling Mixed-Use Buildings Multi-family buildings are often designed as mixed-use and include such space-types as residential, retail, community room, office, and lobby. Because the lighting and mechanical system requirements for the Title 24 Building Energy Efficiency Standards (Title 24) differ for residential and nonresidential occupancies, the energy modeling of these buildings is more complicated.

Events & Trainings The CMFNH team would like to invite you to our Multi-Family Residential New Construction Training series. For descriptions and registration information, please visit our training page or contact Ashley Heath at 866-352-7457 or heath@h-m-g.com.
Under Title 24, the occupancy that comprises less than 20% of the total conditioned floor area can be modeled similarly to the major occupancy (envelope, HVAC, and water heating only). For example, if a residential multi-family building has 5,000 square feet of total conditioned floor area and a small recreation room of 950 square feet, the recreation room can be included in the simulation model because it is 19% of the total conditioned floor area of the building for Title 24 purposes. Because CMFNH provides incentives for residential dwelling units only, though, we typically require a project to remove the nonresidential portion(s) from the Title 24 model. This eliminates any influence (positive or negative) that the nonresidential spaces may have on the overall performance of the residential portion of the building and corresponding incentive amount. Every building is different and mixed-use buildings especially can pose some modeling challenges. Thus, we recommend that you contact us for assistance on mixed-use building types. We will work with you to ensure your project is modeled accurately and eligible for program benefits. For more information, contact Keith Sage at 916962-7001 or sage@h-m-g.com.

A Message from our Partner:
Congratulations to the following developers that recently completed construction and participation in CMFNH! Developer Name - Percent Above 2005 Title 24 Bridge Housing – 27.0% Regis Homes of Northern CA– 21.50% Summer Hill Homes, LLC – 24.80% San Mateo County Community College District – 21.30% Mandarich Developments – 18.80% AMCAL Housing – 16.84% Mid-Peninsula Housing Coalition– 23.10% USA Properties Fund Inc.- 18.20%
CMFNH Updates Program Participation Timing: CMFNH staff often receives questions from multi-family developers USA Properties Fund Inc. regarding the best time to enroll in an incentive program. We recommend initiating discussions as early as possible in the design process in order to minimize costs and maximize efficiency potential. The sooner a project defines its energy efficiency goals, the more cost-effective it is to integrate energy efficiency measures. Incorporating energy efficiency early in the design process fosters an integrative design process and enables passive design strategies and greater energy efficiency options. For more information about the program process and requirements, visit our website: http://multifamily.h-m-g.com/ Design Charrettes: CMFNH offers free services to facilitate energy efficiency design charrettes. The purpose of this charrettes is to gather the entire design team to collaboratively define the project’s energy goals and to establish a plan to meet those goals. Charrettes are key to an integrated design process and critical to ensuring a project’s costeffectiveness. To learn more or to schedule your CMFNH-facilitated design charrette, contact Ashley Heath at 866-3527457 or heath@h-m-g.com
GreenPoint Rated Multifamily New Home The GreenPoint Rated (GPR) program, provided by Build it Green (BIG), serves the single- and multi-family building sector. GPR was recently updated to align with the minimum mandatory requirements of the new California Green Building Code, which will become law in January 2011. Changes affecting the energy efficiency of multi-family projects include: HVAC system design and testing (PJ2) Radiant floor heating (H1) Advanced mechanical ventilation (H4) Solar photovoltaic (I2) Building envelope diagnostics (J2) Net zero energy design (J3) Utility program participation (J5) ENERGY STAR® High-Rise Pilot (PJ3) High-efficacy lighting (M5) Demand response & time-of-use (N6) Design considerations, including acoustics (C1) Commissioning (C3) There are five categories of GPR: Community, Energy, IAQ, Resources, and Water. The Energy category has the highest minimum point requirement (30) and possible points (over 88). For more information about GPR, contact a Build it Green representative. For information on related grants for affordable projects, see Green Building in Alameda County.
