Recoup WWHRS: Products overview: New-build and retrofit optionsRecoup WWHRS
Recoup produce a range of SAP-listed, highly efficient Waste Water Heat Recovery systems for Showers (WWHRS) which extract waste heat energy from used shower water in order to pre-heat the incoming cold feed. This simple solution offers one of the best ‘pound for points’ ratios of any SAP measure and is a true ‘fit and forget’ product, and ultimately can save up to 67% of the energy cost each time a shower is used (regardless of heat source).
For new-build residential, WWHRS can simply be used with a 'Fabric-first' approach, often in place of other more expensive SAP measures such as Solar thermal, ASHP, PV or triple glazing, but for a fraction of the cost. It is an ideal option for residential modular build designs as well as student accommodation builds; hotels or leisure facilities.
Furthermore, it requires no complex installation or commissioning; no ongoing or planned maintenance; no end-user interaction; and has no moving or mechanical parts - Just on-demand, passive energy savings with every shower.
The document discusses the techno-economic analysis of wind power investments, including calculation of key economic indicators such as net present value (NPV), internal rate of return (IRR), payback period, levelized cost of electricity (LCOE), and profitability index (PI). It provides definitions and formulas for each indicator, and highlights their advantages and weaknesses. The document also presents a numerical case study analyzing the economic feasibility of a 20MW wind farm project in Greece based on these indicators.

In the 20th century, we have spent a lot of money and resources to build cultural wastelands that adversely affects our quality-of-life. With the demise of redevelopment in California, in conjunction with the demonization of Smart Growth, the future relevancy of these places rests upon our ability repurpose these miles and miles of regrettable and devalued strip centers, office parks, and housing tracks. Unfortunately, most citizens oppose any new development due to its potential conflict with their existing community character. Applying an urban design technique that purposely codes for a specific community character, this presentation will outline 21st century urban design tools to build towards walkable, mixed-use neighborhood centers.

Kaid will discuss the opportunities and advantages of creating a sustainable energy future.We once thought of cities as the antithesis of sustainability - but we now know that cities can be the solution to, not the cause of, our environmental threats. To take advantage of the opportunities before us in an increasingly urban society, we must be thoughtful, shaping our metropolitan regions to reduce our environmental footprint while creating beautiful, green, inclusive neighborhoods within them. As people concerned about the health and future of the planet, we must approach this task with energy and humility, paying every bit as much attention to nurturing great people habit as we do to conserving the habitats of other species.
This document summarizes the San Joaquin Valley Air Pollution Control District's (SJVAPCD) Drive Clean! Rebate Program. The program provides rebates of $1,000-$3,000 for purchasing or leasing new low-emission vehicles to encourage reducing emissions. It was created by revising an earlier incentive program to streamline the application process based on collaboration with state agencies. The goals are to increase the use of electric vehicles and funding for associated charging infrastructure valleywide.
This document discusses electric vehicles from the perspective of a utility and some of the impacts and opportunities that electric vehicles present. It notes that widespread electric vehicle adoption could nearly double the electrical demand of the average home. However, utilities can mitigate increased loads through infrastructure upgrades and smart grid technologies that allow for optimized and flexible charging. The utility discussed has received a smart grid grant and deployed smart meters, and is considering time-of-use rates and smart charging integration to help manage electric vehicle loads.
The document announces a workshop on electric vehicles (EVs) to take place on July 21 in Modesto. The workshop will include presentations on the basics of EVs, local and state incentives for purchasing EVs, how EVs impact the electric grid and utility bills, and a panel of local EV drivers sharing their experiences. Speakers will come from the California Center for Sustainable Energy, the Mayor of Ceres, the San Joaquin Valley Air Pollution Control District, and Modesto Irrigation District. The goal is to educate attendees on the benefits and opportunities of electric vehicles.
Michelle Kaufmann will talk about a quest for simplicity as a core component to a mission of making thoughtful, sustainable design accessible.
She will talk about her work in prefabrication, design-build, green homes and sustainable communities. Rethinking not only what we make and how we make it, but also redesigning the design process itself is key to the future of architecture and sustainability. Innovations in this category are abundant and exciting, and with strategic focus can help us all to have more quality, less clutter and simpler lives.
The upcoming 2013 Title-24 Building Efficiency Standards were approved by the California Energy Commission on May 9, 2012. The new Title-24 energy code incorporates significant changes that will affect architects, builders, contractors, energy consultants, and solar PV installers. This class will review the upcoming changes to the energy code and the impact on building design along with compliance strategies that will allow you to comply with the new, stricter energy code cost effectively.
Mark Madison is a Certified Energy Plans Examiner, Certified Energy Analyst, HERS rater, and serves on the board of directors of the California Association of Building Energy Analysts (CABEC).
The document discusses methods for harvesting rainwater and reusing greywater for landscape irrigation in order to conserve potable water supplies. It describes the components of a basic rainwater harvesting system and their benefits. It also outlines the process for estimating water supply and demand from rainfall. The document provides examples of different rainwater storage tank designs both above and below ground. It further discusses systems for recycling greywater from clothes washers and entire homes through subsurface drip irrigation and constructed wetlands.
Many building owners have the desire to upgrade their commercial
properties, but in the current state of the economy they are at a loss as to how to financial such upgrades. The presentation will also review current trends in rebates, public sector financing and private sector financing that make such upgrades possible.
Target Audience:
I think the target audience for this presentation will be building industry
professionals, developers, building owners, property managers and
commercial real estate brokers, as well as educators from real estate
development programs such as San Diego State’s.
How the people of a small town on the cross road to the silk road in Persia used micro-climate and their local materials to create energy-efficient buildings.
- Assess how they have used sun, wind and water
- Passive solar design
- Landscape and thermal mass to transform a harsh natural environment into comfortable spaces
- Evaluate innovative uses of local material in their buildings
- Santa Fe architecture and similarities to Persian architecture
- Observe the use of these techniques in modern architecture
Storm windows, insulating shades, sash replacements, awnings - The good news is that we have so many ways to improve the performance of our windows. The bad news is...there are so many ways to improve the performance of our windows! How in the world can we objectively compare them on price, thermal performance, ease of installation, ease of use, solar control, privacy, and durability?
Lawrence Berkeley National Laboratories and BuildingGreen are working on simple and easy-to-use resources for selecting window retrofit options. With input on climate, existing window attributes, and performance priorities, anyone can cut through the difficulties of deciding how to improve the overall performance of existing windows.
Using resources from www.windowattachments.org, webinar participants will work through window attachment selection scenarios with the instructor and learn how to use these resources with their clients and on their own projects.
The new 2008 Title-24 Building Efficiency Standards became effective January 1, 2010. One of the most sweeping changes involve residential indoor and outdoor lighting requirements, particularly kitchen lighting and the new adoption of ASHRAE 62.2 indoor air quality code.
Kitchen Lighting, Title-24
New restrictions, control requirements, high efficacy fixture requirements and incandescent allowances, and interior lighting worksheets will add an additional layer of complexity to residential lighting design. This class will bring you up to speed on the new changes and address the underlying principles, calculation methods, strategies to assist you in complying with the new code changes and take you step by step thru the new CF-6R-LTG-1 lighting certificate of installation which must be filled out before the final certificate of occupancy will be issued.
Kitchen Lighting, Title-24
You will also understand which fixtures will comply as high efficacy (not all LED fixtures are certified as high efficacy), the lighting control requirements for each room type and the new fixture and control requirements for residential outdoor lighting.
Title-24, Title-24
California has now adopted the requirements of ASHRAE 62.2-2007 which means that starting January 1, 2010, all low-rise residential buildings are required to install whole house mechanical ventilation and satisfy other requirements to achieve acceptable indoor air quality. Openable windows will no longer be an acceptable method for satisfying outdoor air requirements. This will involve calculations for determining the minimum ventilation cfm and designing a system to provide the necessary airflow with proper controls. You will learn the proper method for determining ventilation airflow, strategies for designing a cost effective ventilation system, and how to fill out the new ventilation Certificate of Installation.
Kitchen Lighting, Title-24
Learn from one of the leading experts in California’s Title-24 Building Efficiency Standards (Title-24), Mark Madison, a state certified Energy Plans Examiner and Certified Energy Analyst, HERS rater, Greenpoint rater with over 25 years experience with building energy code compliance analysis, enforcement and training.

30
31. Metering Requirements
Purposes of Metering
1) Customer Performance Metering (CPM)
• Provides performance data to system owner
• Required for systems larger than 30kWth
2) True-up Payment (70/30)
• Required for systems>250kWth
• Requires CPM
*Metering is encouraged for all projects regardless of requirements
31
32. Commercial/Multi-family: 30kWth - 250kWth
• Customer Performance Metering (CPM) is Required
• One-time/lump sum incentive payment
• Incentive based on estimated therm or kWh
savings provided by the OG-100 Calculator
• Paid after project is completed, approved, and
inspected (if applicable)
32
33. Commercial/Multi-family > 250kWth
70/30 True-Up Payment
• Customer Performance Metering (CPM) is required
• Payment made in two parts:
1) OG-100 calculator estimates therm or kWh savings. PA
pays 70 percent of that incentive after Incentive Claim and
Inspection (if applicable) are approved
2) System is then metered/monitored for 12 consecutive
months. PA pays the true-up incentive amount by
subtracting the initial 70 percent incentive payment from
the final metered incentive amount.
*Program will pay no more than 110% of estimated incentive
33
34. 70/30 True-up Example
Actual energy savings less than expected
1. OG-100 Calculator Estimation: 12,000 therms displaced annually
(12,000 therms x $12.82/therm) = $153,840 incentive
2. 70% Payment: Once the project is completed, approved, and inspected
(if applicable), PA pays 70 percent of estimated incentive
($153,840 x .70) = $107,688
3. Meter for 12 months: ex: based on 12 months of performance metering
actual savings equals 10,500 therms saved (not 12,000 estimated)
4. Calculate Maximum Incentive (based on metered data): 10,500 therms
(10,500 therms x $12.82/therm) = $134,610 incentive
5. Calculate Final 30% Payment: Maximum Incentive minus 70% payment:
$134,610- $107,688 = $26,922
34
35. Metering Communication Requirements
70/30 True-up Metering requires a Program
Performance Data (PPD) provider
• PPD provider is a service provider that monitors and
reports energy delivery data from SWH systems to PA
• PPD provider must be approved by PAs
• Application found in Handbook and
www.GoSolarCalifornia.com website
• PPD provider must monitor, trend, archive and report
fields as required in Handbook Table 10
• See CSI Thermal Handbook Section for more
information

42
43. Single Family Residential Incentives
• Incentive is based on the following factors:
1. Estimated energy savings
(Based on SRCC OG-300 rating in CEC climate
zones)
2. Incentive Level
3. Shade Factor
4. Surface Orientation Factor (SOF)
*The calculator on www.csithermal.com will automatically
calculate your incentive.
43
45. Incentive Calculation Factors:
1. Climate Zones
• Different climate
zones will have
different sun exposure
• Check the CEC’s
website for climate
zones by zip code:
http://www.energy.ca.gov/maps/renewable/building_climate_zones.html

46. SRCC System Schematic
Conversion Factor To Convert:
1 therm = 29.3 kWh 2241kWh = .03413 therms x 2241
1 kWh = 0.03413 therms = 76.48 therms
46
47. Incentive Calculation Factors:
2. Incentive Level
• Based on the current step level of either
electric/propane or natural gas
47
48. Incentive Calculation Factors:
3. Shade Factor
• For each percentage of average annual availability below 100% on
the collector(s) between 10am and 3pm, there will be an equal
percentage reduction in the system incentive payment down to
85%.
• Example: 95% solar availability between 10am and 3pm =
5% incentive reduction
48
51. Calculate Shade Factor
• Add total hours of shading between 10am and
3pm, based on shade analysis results
• Divide by total hours in the year between 10am
and 3pm (5 hrs. x 365 days = 1825 hours of shading/ yr.)
• Example: 135 hours of shading/1825 hours= 7%
• Shade Factor = 93%
51
52. Incentive Calculation Factors:
4. Surface Orientation Factor (SOF)
SOF value is determined by Tilt and Azimuth
• The ideal SOF = 1.0; Minimum SOF required = .75
• SOF less than 1.0 receives a lesser incentive
• SOF less than .75 is not eligible for an incentive
52
53. Collector Tilt
• Tilt - Angle at which the collectors are
mounted relative to 0º (flat horizontal surface)
Ex. 30º tilt angleº
53
54. Azimuth
Magnetic North is measured using a compass, which does not represent
the true north point because of the Earth’s magnetic fields
True Azimuth is the angle between Magnetic North Point and the
direction the direction panels are facing
